------------------
From: Ben Hutchings <benh@debian.org>
Commit 5afd032961e8 "perf cs-etm: Don't flush when packet_queue fills
up" uses i as a loop counter in cs_etm__process_queues(). It was
backported to the 5.4 and 5.10 stable branches, but the i variable
doesn't exist there as it was only added in 5.15.
Declare i with the expected type.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ben Hutchings <benh@debian.org>
Commit ebbe26fd54a9 "udf: Avoid excessive partition lengths"
introduced a use of check_add_overflow() with argument types u32,
size_t, and u32 *.
This was backported to the 5.x stable branches, where in 64-bit
configurations it results in a build error (with older compilers) or a
warning. Before commit d219d2a9a92e "overflow: Allow mixed type
arguments", which went into Linux 6.1, mixed type arguments are not
supported. That cannot be backported to 5.4 or 5.10 as it would raise
the minimum compiler version for these kernel versions.
Add a cast to make the argument types compatible.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kees Cook <keescook@chromium.org>
commit 9b80e4c4ddaca3501177ed41e49d0928ba2122a8 upstream.
Since the destination variable of the check_*_overflow() helpers will
contain a wrapped value on failure, it would be best to make sure callers
really did check the return result of the helper. Adjust the macros to use
a bool-wrapping static inline that is marked with __must_check. This means
the macros can continue to have their type-agnostic behavior while gaining
the function attribute (that cannot be applied directly to macros).

------------------
From: Kees Cook <keescook@chromium.org>
commit d219d2a9a92e39aa92799efe8f2aa21259b6dd82 upstream.
When the check_[op]_overflow() helpers were introduced, all arguments
were required to be the same type to make the fallback macros simpler.
However, now that the fallback macros have been removed[1], it is fine
to allow mixed types, which makes using the helpers much more useful,
as they can be used to test for type-based overflows (e.g. adding two
large ints but storing into a u8), as would be handy in the drm core[2].
Remove the restriction, and add additional self-tests that exercise
some of the mixed-type overflow cases, and double-check for accidental
macro side-effects.

[ Upstream commit 07a10767853adcbdbf436dc91393b729b52c4e81 ]
The AFS directory format structure, union afs_xdr_dir_block::meta, has too
many alloc counter slots declared and so pushes the hash table along and
over the data. This doesn't cause a problem at the moment because I'm
currently ignoring the hash table and only using the correct number of
alloc_ctrs in the code anyway. In future, however, I should start using
the hash table to try and speed up afs_lookup().
Fix this by using the correct constant to declare the counter array.

[ Upstream commit 844b8cdc681612ff24df62cdefddeab5772fadf1 ]
Following process can cause nbd_config UAF:
1) grab nbd_config temporarily;
2) nbd_genl_disconnect() flush all recv_work() and release the
initial reference:
nbd_genl_disconnect
nbd_disconnect_and_put
nbd_disconnect
flush_workqueue(nbd->recv_workq)
if (test_and_clear_bit(NBD_RT_HAS_CONFIG_REF, ...))
nbd_config_put
-> due to step 1), reference is still not zero
3) nbd_genl_reconfigure() queue recv_work() again;
nbd_genl_reconfigure
config = nbd_get_config_unlocked(nbd)
if (!config)
-> succeed
if (!test_bit(NBD_RT_BOUND, ...))
-> succeed
nbd_reconnect_socket
queue_work(nbd->recv_workq, &args->work)
4) step 1) release the reference;
5) Finially, recv_work() will trigger UAF:
recv_work
nbd_config_put(nbd)
-> nbd_config is freed
atomic_dec(&config->recv_threads)
-> UAF
Fix the problem by clearing NBD_RT_BOUND in nbd_genl_disconnect(), so

------------------
From: Ivan Stepchenko <sid@itb.spb.ru>
[ Upstream commit 357445e28ff004d7f10967aa93ddb4bffa5c3688 ]
The function atomctrl_get_smc_sclk_range_table() does not check the return
value of smu_atom_get_data_table(). If smu_atom_get_data_table() fails to
retrieve SMU_Info table, it returns NULL which is later dereferenced.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
In practice this should never happen as this code only gets called
on polaris chips and the vbios data table will always be present on
those chips.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thadeu Lima de Souza Cascardo <cascardo@igalia.com>
[ Upstream commit 8559a9e0c457729fe3edb3176bbf7c7874f482b0 ]
Just like in commit 4dfde294b979 ("rtlwifi: rise completion at the last
step of firmware callback"), only signal completion once the function is
finished. Otherwise, the module removal waiting for the completion could
free the memory that the callback will still use before returning.

rtl_init_core creates a workqueue that is then assigned to rtl_wq.
rtl_deinit_core does not destroy it. It is left to rtl_usb_deinit, which
must be called in the probe error path.

------------------
From: Jakob Koschel <jakobkoschel@gmail.com>
[ Upstream commit a0ff2a87194a968b9547fd4d824a09092171d1ea ]
To move the list iterator variable into the list_for_each_entry_*()
macro in the future it should be avoided to use the list iterator
variable after the loop body.
To *never* use the list iterator variable after the loop it was
concluded to use a separate iterator variable instead of a
found boolean [1].
This removes the need to use a found variable and simply checking if
the variable was set, can determine if the break/goto was hit.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thadeu Lima de Souza Cascardo <cascardo@igalia.com>
[ Upstream commit 2fdac64c3c35858aa8ac5caa70b232e03456e120 ]
Commit 2461c7d60f9f ("rtlwifi: Update header file") introduced a global
list of private data structures.
Later on, commit 26634c4b1868 ("rtlwifi Modify existing bits to match
vendor version 2013.02.07") started adding the private data to that list at
probe time and added a hook, check_buddy_priv to find the private data from
a similar device.
However, that function was never used.
Besides, though there is a lock for that list, it is never used. And when
the probe fails, the private data is never removed from the list. This
would cause a second probe to access freed memory.
Remove the unused hook, structures and members, which will prevent the
potential race condition on the list and its corruption during a second
probe when probe fails.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thadeu Lima de Souza Cascardo <cascardo@igalia.com>
[ Upstream commit e7ceefbfd8d447abc8aca8ab993a942803522c06 ]
Deinitialize at reverse order when probe fails.
When init_sw_vars fails, rtl_deinit_core should not be called, specially
now that it destroys the rtl_wq workqueue.
And call rtl_pci_deinit and deinit_sw_vars, otherwise, memory will be
leaked.
Remove pci_set_drvdata call as it will already be cleaned up by the core
driver code and could lead to memory leaks too. cf. commit 8d450935ae7f
("wireless: rtlwifi: remove unnecessary pci_set_drvdata()") and
commit 3d86b93064c7 ("rtlwifi: Fix PCI probe error path orphaned memory").

------------------
From: Thadeu Lima de Souza Cascardo <cascardo@igalia.com>
[ Upstream commit b59b86c5d08be7d761c04affcbcec8184738c200 ]
At probe error path, the firmware loading work may have already been
queued. In such a case, it will try to access memory allocated by the probe
function, which is about to be released. In such paths, wait for the
firmware worker to finish before releasing memory.

Commit 'cpupower: Make TSC read per CPU for Mperf monitor' (c2adb1877b7)
changes TSC counter reads per cpu, but left time diff global (from start
of all cpus to end of all cpus), thus diff(time) is too large for a
cpu's tsc counting, resulting in far less than acutal TSC_Mhz and thus
`cpupower monitor` showing far less than actual cpu realtime frequency.
/proc/cpuinfo shows frequency:
cat /proc/cpuinfo | egrep -e 'processor' -e 'MHz'
...
processor : 171
cpu MHz : 4108.498

------------------
From: Octavian Purdila <tavip@google.com>
[ Upstream commit 3fff5da4ca2164bb4d0f1e6cd33f6eb8a0e73e50 ]
Prevent adding a device which is already a team device lower,
e.g. adding veth0 if vlan1 was already added and veth0 is a lower of
vlan1.
This is not useful in practice and can lead to recursive locking:
$ ip link add veth0 type veth peer name veth1
$ ip link set veth0 up
$ ip link set veth1 up
$ ip link add link veth0 name veth0.1 type vlan protocol 802.1Q id 1
$ ip link add team0 type team
$ ip link set veth0.1 down
$ ip link set veth0.1 master team0
team0: Port device veth0.1 added
$ ip link set veth0 down
$ ip link set veth0 master team0

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Joe Hattori <joe@pf.is.s.u-tokyo.ac.jp>
[ Upstream commit dddca3b2fc676113c58b04aaefe84bfb958ac83e ]
of_regulator_match() does not release the OF node reference in the error
path, resulting in an OF node leak. Therefore, call of_node_put() on the
obtained nodes before returning the EINVAL error.
Since it is possible that some drivers call this function and do not
exit on failure, such as s2mps11_pmic_driver, clear the init_data and
of_node in the error path.
This was reported by an experimental verification tool that I am
developing. As I do not have access to actual devices nor the QEMU board
configuration to test drivers that call this function, no runtime test
was able to be performed.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kees Cook <keescook@chromium.org>
[ Upstream commit d088c92802549fc1cf77a12a4e3986160d63662a ]
Since forever the harness output for signed value tests have reported
unsigned values to avoid casting. Instead, actually test the variable
types and perform the correct casts and choose the correct format
specifiers.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dmitry V. Levin <ldv@strace.io>
[ Upstream commit 02bc220dc6dc7c56edc4859bc5dd2c08b95d5fb5 ]
intptr_t and uintptr_t are not big enough types on 32-bit architectures
when printing 64-bit values, resulting to the following incorrect
diagnostic output:
# get_syscall_info.c:209:get_syscall_info:Expected exp_args[2] (3134324433) == info.entry.args[1] (3134324433)
Replace intptr_t and uintptr_t with intmax_t and uintmax_t, respectively.
With this fix, the same test produces more usable diagnostic output:
# get_syscall_info.c:209:get_syscall_info:Expected exp_args[2] (3134324433) == info.entry.args[1] (18446744072548908753)

From: Bo Gan <ganboing@gmail.com>
[ Upstream commit d7f12857f095ef38523399d47e68787b357232f6 ]
In wrpll_configure_for_rate() we try to determine the best PLL
configuration for a target rate. However, in the loop where we try
values of R, we should compare the derived `vco` with `target_vco_rate`.
However, we were in fact comparing it with `target_rate`, which is
actually after Q shift. This is incorrect, and sometimes can result in
suboptimal clock rates. Fix it.

The reproduction command is as follows:
sysctl -w net.core.dev_weight=0
ping 127.0.0.1
This is because when the napi's weight is set to 0, process_backlog() may
return 0 and clear the NAPI_STATE_SCHED bit of napi->state, causing this
napi to be re-polled in net_rx_action() until __do_softirq() times out.
Since the NAPI_STATE_SCHED bit has been cleared, napi_schedule_rps() can
be retriggered in enqueue_to_backlog(), causing this issue.
Making the napi's weight always non-zero solves this problem.
Triggering this issue requires system-wide admin (setting is
not namespaced).

From: Maher Sanalla <msanalla@nvidia.com>
[ Upstream commit 70d81f25cc92cc4e914516c9935ae752f27d78ad ]
Currently, mlxfw kernel module limits FW flash image size to be
10MB at most, preventing the ability to burn recent BlueField-3
FW that exceeds the said size limit.
Thus, drop the hard coded limit. Instead, rely on FW's
max_component_size threshold that is reported in MCQI register
as the size limit for FW image.

qdisc plug 2: dev lo parent 1:1
qdisc pfifo 4: dev lo parent 3:1 limit 1000p
qdisc drr 3: dev lo parent 1:2
step10. trigger the bug <=== prevented by this patch
tc qdisc replace dev lo parent 1:3 handle 4:0
step 11. Redisplay again the qdiscs/classes
tc class ls dev lo
class drr 1:1 root leaf 2: quantum 64Kb
class drr 1:2 root leaf 3: quantum 64Kb
class drr 1:3 root leaf 4: quantum 64Kb
class drr 3:1 root leaf 4: quantum 64Kb
tc qdisc ls
qdisc drr 1: dev lo root refcnt 2
qdisc plug 2: dev lo parent 1:1
qdisc pfifo 4: dev lo parent 3:1 refcnt 2 limit 1000p
qdisc drr 3: dev lo parent 1:2
Observe that a) parent for 4:0 does not change despite the replace request.
There can only be one parent. b) refcount has gone up by two for 4:0 and
c) both class 1:3 and 3:1 are pointing to it.
Step 12. send one packet to plug
echo "" | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888,priority=$((0x10001))
step13. send one packet to the grafted fifo
echo "" | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888,priority=$((0x10003))
step14. lets trigger the uaf
tc class delete dev lo classid 1:3
tc class delete dev lo classid 1:1
The semantics of "replace" is for a del/add _on the same node_ and not
a delete from one node(3:1) and add to another node (1:3) as in step10.
While we could "fix" with a more complex approach there could be
consequences to expectations so the patch takes the preventive approach of
"disallow such config".

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marco Leogrande <leogrande@google.com>
[ Upstream commit e2f0791124a1b6ca8d570110cbd487969d9d41ef ]
Commit f803bcf9208a ("selftests/bpf: Prevent client connect before
server bind in test_tc_tunnel.sh") added code that waits for the
netcat server to start before the netcat client attempts to connect to
it. However, not all calls to 'server_listen' were guarded.
This patch adds the existing 'wait_for_port' guard after the remaining
call to 'server_listen'.

------------------
From: George Lander <lander@jagmn.com>
[ Upstream commit 0a2319308de88b9e819c0b43d0fccd857123eb31 ]
There have been intermittent issues with the SPDIF output on H3
and H2+ devices which has been fixed by setting the s_clk to 4
times the audio pll.
Add a quirk for the clock multiplier as not every supported SoC
requires it. Without the multiplier, the audio at normal sampling
rates was distorted and did not play at higher sampling rates.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnaldo Carvalho de Melo <acme@redhat.com>
[ Upstream commit 058b38ccd2af9e5c95590b018e8425fa148d7aca ]
Recently we got a case where a kernel sample wasn't being resolved due
to a bug that was not setting the end address on kernel functions
implemented in assembly (see Link: tag), and then those were not being
found by machine__resolve() -> map__find_symbol().
So we ended up with:
# perf top --stdio
PerfTop: 0 irqs/s kernel: 0% exact: 0% lost: 0/0 drop: 0/0 [cycles/P]
-----------------------------------------------------------------------
Warning:
A vmlinux file was not found.
Kernel samples will not be resolved.
^Z
[1]+ Stopped perf top --stdio
#
But then resolving all other kernel symbols.
So just fixup the logic to only print that warning when there are no
symbols in the kernel map.

From: Puranjay Mohan <puranjay@kernel.org>
[ Upstream commit 87c544108b612512b254c8f79aa5c0a8546e2cc4 ]
BPF programs can execute in all kinds of contexts and when a program
running in a non-preemptible context uses the bpf_send_signal() kfunc,
it will cause issues because this kfunc can sleep.
Change `irqs_disabled()` to `!preemptible()`.

Smatch generates the following false error report:

Traditionally, we are not changing kernel code and asking people to fix
the tools. However in this case, the fix can be done by simply rearranging
the code to be more clear.

From: Chen-Yu Tsai <wenst@chromium.org>
[ Upstream commit a6d5983e40f5d5b219337569cdd269727f5a3e2e ]
The "regulator-compatible" property has been deprecated since 2012 in
commit 13511def87b9 ("regulator: deprecate regulator-compatible DT
property"), which is so old it's not even mentioned in the converted
regulator bindings YAML file. It is also not listed in the MT6397
regulator bindings. Having them present produces a whole bunch of
validation errors:
Unevaluated properties are not allowed ('regulator-compatible' was unexpected)
Drop the "regulator-compatible" property from the board dts. The
property values are the same as the node name, so everything should
continue to work.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chen-Yu Tsai <wenst@chromium.org>
[ Upstream commit 9545ba142865b9099d43c972b9ebcf463606499a ]
The MT6397 PMIC bindings specify exact names for its sub-nodes. The
names used in the current dts don't match, causing a validation error.
Fix up the names. Also drop the label for the regulators node, since
any reference should be against the individual regulator sub-nodes.

[ Upstream commit de124b61e179e690277116e6be512e4f422b5dd8 ]
dss_of_port_get_parent_device() leaks an OF node reference when i >= 2
and struct device_node *np is present. Since of_get_next_parent()
obtains a reference of the returned OF node, call of_node_put() before
returning NULL.
This was found by an experimental verifier that I am developing, and no
runtime test was able to be performed due to that lack of actual
devices.

From: Zijun Hu <quic_zijuhu@quicinc.com>
[ Upstream commit d4929755e4d02bd3de3ae5569dab69cb9502c54f ]
The devm_pci_epc_destroy() comment says destroys the EPC device, but it
does not actually do that since devres_destroy() does not call
devm_pci_epc_release(), and it also can not fully undo what the API
devm_pci_epc_create() does, so it is faulty.
Fortunately, the faulty API has not been used by current kernel tree. Use
devres_release() instead of devres_destroy() so the EPC device will be
released.

------------------
From: Joe Hattori <joe@pf.is.s.u-tokyo.ac.jp>
[ Upstream commit 094f5c315f756b19198e6c401aa821ac0e868750 ]
imx_media_add_of_subdevs() calls of_parse_phandle() and passes the
obtained node to imx_media_of_add_csi(). The passed node is used in
v4l2_async_nf_add_fwnode(), which increments the refcount of the node.
Therefore, while the current implementation only releases the node when
imx_media_of_add_csi() fails, but should always release it. Call
of_node_put() right after imx_media_of_add_csi().

Currently, the code does:
if (x == 0) {
x &= ~0x3;
x |= 0x1;
}
Zeroing bits 0 and 1 of a variable that is 0 is not necessary. So directly
set the variable to 1.

ocfs2_release_dquot() is much like dquot_release(), which is called by
ext4 to handle similar situation. So here fix it by marking the dquot as
inactive like what dquot_release() does.

[ Upstream commit a145c848d69f9c6f32008d8319edaa133360dd74 ]
dereference_symbol_descriptor() needs to obtain the module pointer
belonging to pointer in order to resolve that pointer.
The returned mod pointer is obtained under RCU-sched/ preempt_disable()
guarantees and needs to be used within this section to ensure that the
module is not removed in the meantime.
Extend the preempt_disable() section to also cover
dereference_module_function_descriptor().

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Joe Hattori <joe@pf.is.s.u-tokyo.ac.jp>
[ Upstream commit e883c64778e5a9905fce955681f8ee38c7197e0f ]
The .probe() of edma_driver calls of_parse_phandle_with_fixed_args() but
does not release the obtained OF nodes. Thus add a of_node_put() call.
This bug was found by an experimental verification tool that I am
developing.

From: Oleksij Rempel <o.rempel@pengutronix.de>
[ Upstream commit 3ab8c5ed4f84fa20cd16794fe8dc31f633fbc70c ]
The nvmem interface supports variable buffer sizes, while the regmap
interface operates with fixed-size storage. If an nvmem client uses a
buffer size less than 4 bytes, regmap_read will write out of bounds
as it expects the buffer to point at an unsigned int.
Fix this by using an intermediary unsigned int to hold the value.

alias to "struct sk_buff_head unresolved", which contain two pointers.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wentao Liang <vulab@iscas.ac.cn>
[ Upstream commit e20a70c572539a486dbd91b225fa6a194a5e2122 ]
In hibernation_platform_enter(), the code did not check the
return value of syscore_suspend(), potentially leading to a
situation where syscore_resume() would be called even if
syscore_suspend() failed. This could cause unpredictable
behavior or system instability.
Modify the code sequence in question to properly handle errors returned
by syscore_suspend(). If an error occurs in the suspend path, the code
now jumps to label 'Enable_irqs' skipping the syscore_resume() call and
only enabling interrupts after setting the system state to SYSTEM_RUNNING.

From: Eric Dumazet <edumazet@google.com>
[ Upstream commit 5de7665e0a0746b5ad7943554b34db8f8614a196 ]
Rose timers only acquire the socket spinlock, without
checking if the socket is owned by one user thread.
Add a check and rearm the timers if needed.

From: Chenyuan Yang <chenyuan0y@gmail.com>
[ Upstream commit 19e65c45a1507a1a2926649d2db3583ed9d55fd9 ]
dm is netdev private data and it cannot be
used after free_netdev() call. Using dm after free_netdev()
can cause UAF bug. Fix it by moving free_netdev() at the end of the
function.
This is similar to the issue fixed in commit
ad297cd2db89 ("net: qcom/emac: fix UAF in emac_remove").
This bug is detected by our static analysis tool.

[ Upstream commit c7b87ce0dd10b64b68a0b22cb83bbd556e28fe81 ]
libtraceevent parses and returns an array of argument fields, sometimes
larger than RAW_SYSCALL_ARGS_NUM (6) because it includes "__syscall_nr",
idx will traverse to index 6 (7th element) whereas sc->fmt->arg holds 6
elements max, creating an out-of-bounds access. This runtime error is
found by UBsan. The error message:

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Masahiro Yamada <masahiroy@kernel.org>
[ Upstream commit 45c9c4101d3d2fdfa00852274bbebba65fcc3cf2 ]
When a symbol that is already registered is added again, __add_symbol()
returns without freeing the symbol definition, making it unreachable.
The following test cases demonstrate different memory leak points.
[Test Case 1]
Forward declaration with exactly the same definition
$ cat foo.c
#include <linux/export.h>
void foo(void);
void foo(void) {}
EXPORT_SYMBOL(foo);
[Test Case 2]
Forward declaration with a different definition (e.g. attribute)
$ cat foo.c
#include <linux/export.h>
void foo(void);
__attribute__((__section__(".ref.text"))) void foo(void) {}
EXPORT_SYMBOL(foo);
[Test Case 3]
Preserving an overridden symbol (compile with KBUILD_PRESERVE=1)
$ cat foo.c
#include <linux/export.h>
void foo(void);
void foo(void) { }
EXPORT_SYMBOL(foo);
$ cat foo.symref
override foo void foo ( int )
The memory leaks in Test Case 1 and 2 have existed since the introduction
of genksyms into the kernel tree. [1]
The memory leak in Test Case 3 was introduced by commit 5dae9a550a74
("genksyms: allow to ignore symbol checksum changes").
When multiple init_declarators are reduced to an init_declarator_list,
the decl_spec must be duplicated. Otherwise, the following Test Case 4
would result in a double-free bug.
[Test Case 4]
$ cat foo.c
#include <linux/export.h>
extern int foo, bar;
int foo, bar;
EXPORT_SYMBOL(foo);
In this case, 'foo' and 'bar' share the same decl_spec, 'int'. It must
be unshared before being passed to add_symbol().

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Masahiro Yamada <masahiroy@kernel.org>
[ Upstream commit be2fa44b5180a1f021efb40c55fdf63c249c3209 ]
When a symbol that is already registered is read again from *.symref
file, __add_symbol() removes the previous one from the hash table without
freeing it.
[Test Case]
$ cat foo.c
#include <linux/export.h>
void foo(void);
void foo(void) {}
EXPORT_SYMBOL(foo);
$ cat foo.symref
foo void foo ( void )
foo void foo ( void )
When a symbol is removed from the hash table, it must be freed along
with its ->name and ->defn members. However, sym->name cannot be freed
because it is sometimes shared with node->string, but not always. If
sym->name and node->string share the same memory, free(sym->name) could
lead to a double-free bug.
To resolve this issue, always assign a strdup'ed string to sym->name.
Fixes: 64e6c1e12372 ("genksyms: track symbol checksum changes")

[ Upstream commit 8a20030038742b9915c6d811a4e6c14b126cafb4 ]
Sparse reports
net/ipv4/inet_diag.c:1511:17: sparse: sparse: Using plain integer as NULL pointer
Due to this code calling cmpxchg on a non-integer type
struct inet_diag_handler *
return !cmpxchg((const struct inet_diag_handler**)&inet_diag_table[type],

While hexagon's cmpxchg assigns an integer value to a variable of this
type.

Update this assignment to cast 0 to the correct type.
The original issue is easily reproduced at head with the below block,

die executes holding the spinlock of &die.lock and unlock

However in the code if the notify_die() returns NOTIFY_STOP
, die() exit with returning 1 but never unlocked the spinlock.
Fix this by adding spin_unlock_irq(&die.lock) before returning.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chuck Lever <chuck.lever@oracle.com>
commit 961b4b5e86bf56a2e4b567f81682defa5cba957e upstream.
I noticed that once an NFSv4.1 callback operation gets a
NFS4ERR_DELAY status on CB_SEQUENCE and then the connection is lost,
the callback client loops, resending it indefinitely.
The switch arm in nfsd4_cb_sequence_done() that handles
NFS4ERR_DELAY uses rpc_restart_call() to rearm the RPC state machine
for the retransmit, but that path does not call the rpc_prepare_call
callback again. Thus cb_seq_status is set to -10008 by the first
NFS4ERR_DELAY result, but is never set back to 1 for the retransmits.
nfsd4_cb_sequence_done() thinks it's getting nothing but a
long series of CB_SEQUENCE NFS4ERR_DELAY replies.

commit a4e17a8f239a545c463f8ec27db4ed6e74b31841 upstream.
In the case of a test that uses the special option ${KERNEL_VERSION} in one
of its settings but has no configuration available in ${OUTPUT_DIR}, for
example if it's a new empty directory, then the `make kernelrelease` call
will fail and the subroutine will chomp an empty string, silently. Fix that
by adding an empty configuration and retrying.

This commit reintroduces interrupt-based card detection previously
used in the rts5139 driver. This functionality was removed in commit
00d8521dcd23 ("staging: remove rts5139 driver code").
Reintroducing this mechanism fixes presence detection for certain card
readers, which with the current driver, will taken approximately 20
seconds to enter S3 as `mmc_rescan` has to be frozen.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alan Stern <stern@rowland.harvard.edu>
commit 64f2657b579343cf923aa933f08074e6258eb07b upstream.
A report in 2019 by the syzbot fuzzer was found to be connected to two
errors in the HID core associated with Resolution Multipliers. One of
the errors was fixed by commit ea427a222d8b ("HID: core: Fix deadloop
in hid_apply_multiplier."), but the other has not been fixed.
This error arises because hid_apply_multipler() assumes that every
Resolution Multiplier control is contained in a Logical Collection,
i.e., there's no way the routine can ever set multiplier_collection to
NULL. This is in spite of the fact that the function starts with a
big comment saying:
* "The Resolution Multiplier control must be contained in the same
* Logical Collection as the control(s) to which it is to be applied.
...
* If no Logical Collection is
* defined, the Resolution Multiplier is associated with all
* controls in the report."
* HID Usage Table, v1.12, Section 4.3.1, p30
*
* Thus, search from the current collection upwards until we find a
* logical collection...
The comment and the code overlook the possibility that none of the
collections found may be a Logical Collection.
The fix is to set the multiplier_collection pointer to NULL if the
collection found isn't a Logical Collection.

------------------
From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
commit c6ef3a7fa97ec823a1e1af9085cf13db9f7b3bac upstream.
If the uvc_status_init() function fails to allocate the int_urb, it will
free the dev->status pointer but doesn't reset the pointer to NULL. This
results in the kfree() call in uvc_status_cleanup() trying to
double-free the memory. Fix it by resetting the dev->status pointer to
NULL after freeing it.

From: Qu Wenruo <wqu@suse.com>
commit d0f038104fa37380e2a725e669508e43d0c503e9 upstream.
There is a recent ML report that mounting a large fs backed by hardware
RAID56 controller (with one device missing) took too much time, and
systemd seems to kill the mount attempt.
In that case, the only error message is:
BTRFS error (device sdj): open_ctree failed
There is no reason on why the failure happened, making it very hard to
understand the reason.
At least output the error number (in the particular case it should be
-EINTR) to provide some clue.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Filipe Manana <fdmanana@suse.com>
[ Upstream commit e2f0943cf37305dbdeaf9846e3c941451bcdef63 ]
When we are trying to join the current transaction and if it's aborted,
we read its 'aborted' field after unlocking fs_info->trans_lock and
without holding any extra reference count on it. This means that a
concurrent task that is aborting the transaction may free the transaction
before we read its 'aborted' field, leading to a use-after-free.
Fix this by reading the 'aborted' field while holding fs_info->trans_lock
since any freeing task must first acquire that lock and set
fs_info->running_transaction to NULL before freeing the transaction.
This was reported by syzbot and Dmitry with the following stack traces
from KASAN:

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Suleiman Souhlal <suleiman@google.com>
[ Upstream commit 108ad0999085df2366dd9ef437573955cb3f5586 ]
When steal time exceeds the measured delta when updating clock_task, we
currently try to catch up the excess in future updates.
However, this results in inaccurate run times for the future things using
clock_task, in some situations, as they end up getting additional steal
time that did not actually happen.
This is because there is a window between reading the elapsed time in
update_rq_clock() and sampling the steal time in update_rq_clock_task().
If the VCPU gets preempted between those two points, any additional
steal time is accounted to the outgoing task even though the calculated
delta did not actually contain any of that "stolen" time.
When this race happens, we can end up with steal time that exceeds the
calculated delta, and the previous code would try to catch up that excess
steal time in future clock updates, which is given to the next,
incoming task, even though it did not actually have any time stolen.
This behavior is particularly bad when steal time can be very long,
which we've seen when trying to extend steal time to contain the duration
that the host was suspended [0]. When this happens, clock_task stays
frozen, during which the running task stays running for the whole
duration, since its run time doesn't increase.
However the race can happen even under normal operation.
Ideally we would read the elapsed cpu time and the steal time atomically,
to prevent this race from happening in the first place, but doing so
is non-trivial.
Since the time between those two points isn't otherwise accounted anywhere,
neither to the outgoing task nor the incoming task (because the "end of
outgoing task" and "start of incoming task" timestamps are the same),
I would argue that the right thing to do is to simply drop any excess steal
time, in order to prevent these issues.

Shifting 1 << 31 on a 32-bit int causes signed integer overflow, which
leads to undefined behavior. To prevent this, cast 1 to u32 before
performing the shift, ensuring well-defined behavior.
This change explicitly avoids any potential overflow by ensuring that
the shift occurs on an unsigned 32-bit integer.

------------------
From: Stas Sergeev <stsp2@yandex.ru>
[ Upstream commit 3ca459eaba1bf96a8c7878de84fa8872259a01e3 ]
Currently tun checks the group permission even if the user have matched.
Besides going against the usual permission semantic, this has a
very interesting implication: if the tun group is not among the
supplementary groups of the tun user, then effectively no one can
access the tun device. CAP_SYS_ADMIN still can, but its the same as
not setting the tun ownership.
This patch relaxes the group checking so that either the user match
or the group match is enough. This avoids the situation when no one
can access the device even though the ownership is properly set.
Also I simplified the logic by removing the redundant inversions:
tun_not_capable() --> !tun_capable()

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp>
[ Upstream commit 3df7546fc03b8f004eee0b9e3256369f7d096685 ]
syzbot is reporting too large allocation warning at tomoyo_write_control(),
for one can write a very very long line without new line character. To fix
this warning, I use __GFP_NOWARN rather than checking for KMALLOC_MAX_SIZE,
for practically a valid line should be always shorter than 32KB where the
"too small to fail" memory-allocation rule applies.
One might try to write a valid line that is longer than 32KB, but such
request will likely fail with -ENOMEM. Therefore, I feel that separately
returning -EINVAL when a line is longer than KMALLOC_MAX_SIZE is redundant.
There is no need to distinguish over-32KB and over-KMALLOC_MAX_SIZE.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Borislav Petkov <bp@alien8.de>
[ Upstream commit 5c0e00a391dd0099fe95991bb2f962848d851916 ]
The GHES driver overrides the panic= setting by force-rebooting the
system after a fatal hw error has been reported. The intent being that
such an error would be reported earlier.
However, this is not optimal when a hard-to-debug issue requires long
time to reproduce and when that happens, the box will get rebooted after
30 seconds and thus destroy the whole hw context of when the error
happened.
So rip out the default GHES panic timeout and honor the global one.
In the panic disabled (panic=0) case, the error will still be logged to
dmesg for later inspection and if panic after a hw error is really
required, then that can be controlled the usual way - use panic= on the
cmdline or set it in the kernel .config's CONFIG_PANIC_TIMEOUT.

commit 269e31aecdd0b70f53a05def79480f15cbcc0fd6 upstream.
There was a change in the mxs-dma engine that uses a new custom flag.
The change was not applied to the mxs spi driver.
This results in chipselect being deasserted too early.
This fixes the chipselect problem by using the new flag in the mxs-spi
driver.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ryusuke Konishi <konishi.ryusuke@gmail.com>
commit 584db20c181f5e28c0386d7987406ace7fbd3e49 upstream.
Patch series "nilfs2: Folio conversions for directory paths".
This series applies page->folio conversions to nilfs2 directory
operations. This reduces hidden compound_head() calls and also converts
deprecated kmap calls to kmap_local in the directory code.
Although nilfs2 does not yet support large folios, Matthew has done his
best here to include support for large folios, which will be needed for
devices with large block sizes.
This series corresponds to the second half of the original post [1], but
with two complementary patches inserted at the beginning and some
adjustments, to prevent a kmap_local constraint violation found during
testing with highmem mapping.
[1] https://lkml.kernel.org/r/20231106173903.1734114-1-willy@infradead.org
I have reviewed all changes and tested this for regular and small block
sizes, both on machines with and without highmem mapping. No issues

This patch (of 17):
In a few directory operations, the call to nilfs_put_page() for a page
obtained using nilfs_find_entry() or nilfs_dotdot() is hidden in
nilfs_set_link() and nilfs_delete_entry(), making it difficult to track
page release and preventing change of its call position.
By moving nilfs_put_page() out of these functions, this makes the page
get/put correspondence clearer and makes it easier to swap
nilfs_put_page() calls (and kunmap calls within them) when modifying
multiple directory entries simultaneously in nilfs_rename().
Also, update comments for nilfs_set_link() and nilfs_delete_entry() to
reflect changes in their behavior.
To make nilfs_put_page() visible from namei.c, this moves its definition
to nilfs.h and replaces existing equivalents to use it, but the exposure
of that definition is temporary and will be removed on a later kmap ->
kmap_local conversion.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ryusuke Konishi <konishi.ryusuke@gmail.com>
commit 8cf57c6df818f58fdad16a909506be213623a88e upstream.
In nilfs_rename(), calls to nilfs_put_page() to release pages obtained
with nilfs_find_entry() or nilfs_dotdot() are alternated in the normal
path.
When replacing the kernel memory mapping method from kmap to
kmap_local_{page,folio}, this violates the constraint on the calling order
of kunmap_local().
Swap the order of nilfs_put_page calls where the kmap sections of multiple
pages overlap so that they are nested, allowing direct replacement of
nilfs_put_page() -> unmap_and_put_page().
Without this reordering, that replacement will cause a kernel WARNING in
kunmap_local_indexed() on architectures with high memory mapping.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ryusuke Konishi <konishi.ryusuke@gmail.com>
commit ee70999a988b8abc3490609142f50ebaa8344432 upstream.
Patch series "nilfs2: fix issues with rename operations".
This series fixes BUG_ON check failures reported by syzbot around rename
operations, and a minor behavioral issue where the mtime of a child
directory changes when it is renamed instead of moved.
This patch (of 2):
The directory manipulation routines nilfs_set_link() and
nilfs_delete_entry() rewrite the directory entry in the folio/page
previously read by nilfs_find_entry(), so error handling is omitted on the
assumption that nilfs_prepare_chunk(), which prepares the buffer for
rewriting, will always succeed for these. And if an error is returned, it
triggers the legacy BUG_ON() checks in each routine.
This assumption is wrong, as proven by syzbot: the buffer layer called by
nilfs_prepare_chunk() may call nilfs_get_block() if necessary, which may
fail due to metadata corruption or other reasons. This has been there all
along, but improved sanity checks and error handling may have made it more
reproducible in fuzzing tests.
Fix this issue by adding missing error paths in nilfs_set_link(),
nilfs_delete_entry(), and their caller nilfs_rename().

From: Ricardo Ribalda <ribalda@chromium.org>
commit d9fecd096f67a4469536e040a8a10bbfb665918b upstream.
Now we keep a reference to the active fh for any call to uvc_ctrl_set,
regardless if it is an actual set or if it is a just a try or if the
device refused the operation.
We should only keep the file handle if the device actually accepted
applying the operation.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ricardo Ribalda <ribalda@chromium.org>
commit 221cd51efe4565501a3dbf04cc011b537dcce7fb upstream.
When an async control is written, we copy a pointer to the file handle
that started the operation. That pointer will be used when the device is
done. Which could be anytime in the future.
If the user closes that file descriptor, its structure will be freed,
and there will be one dangling pointer per pending async control, that
the driver will try to use.
Clean all the dangling pointers during release().
To avoid adding a performance penalty in the most common case (no async
operation), a counter has been introduced with some logic to make sure
that it is properly handled.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Toke Høiland-Jørgensen <toke@redhat.com>
commit 737d4d91d35b5f7fa5bb442651472277318b0bfd upstream.
Even though we fixed a logic error in the commit cited below, syzbot
still managed to trigger an underflow of the per-host bulk flow
counters, leading to an out of bounds memory access.
To avoid any such logic errors causing out of bounds memory accesses,
this commit factors out all accesses to the per-host bulk flow counters
to a series of helpers that perform bounds-checking before any
increments and decrements. This also has the benefit of improving
readability by moving the conditional checks for the flow mode into
these helpers, instead of having them spread out throughout the
code (which was the cause of the original logic error).
As part of this change, the flow quantum calculation is consolidated
into a helper function, which means that the dithering applied to the
ost load scaling is now applied both in the DRR rotation and when a
sparse flow's quantum is first initiated. The only user-visible effect
of this is that the maximum packet size that can be sent while a flow
stays sparse will now vary with +/- one byte in some cases. This should
not make a noticeable difference in practice, and thus it's not worth
complicating the code to preserve the old behaviour.
Fixes: 546ea84d07e3 ("sched: sch_cake: fix bulk flow accounting logic for host fairness")

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: "Thomas Weißschuh" <thomas.weissschuh@linutronix.de>
commit dfc1b168a8c4b376fa222b27b97c2c4ad4b786e1 upstream.
The userprog infrastructure links objects files through $(CC).
Either explicitly by manually calling $(CC) on multiple object files or
implicitly by directly compiling a source file to an executable.
The documentation at Documentation/kbuild/llvm.rst indicates that ld.lld
would be used for linking if LLVM=1 is specified.
However clang instead will use either a globally installed cross linker
from $PATH called ${target}-ld or fall back to the system linker, which
probably does not support crosslinking.
For the normal kernel build this is not an issue because the linker is
always executed directly, without the compiler being involved.
Explicitly pass --ld-path to clang so $(LD) is respected.
As clang 13.0.1 is required to build the kernel, this option is available.
Fixes: 7f3a59db274c ("kbuild: add infrastructure to build userspace programs")

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Romain Perier <romain.perier@gmail.com>
[ Upstream commit 12cc923f1ccc1df467e046b02a72c2b3b321b6a2 ]
Nowadays, modern kernel subsystems that use callbacks pass the data
structure associated with a given callback as argument to the callback.
The tasklet subsystem remains one which passes an arbitrary unsigned
long to the callback function. This has several problems:
- This keeps an extra field for storing the argument in each tasklet
data structure, it bloats the tasklet_struct structure with a redundant
.data field
- No type checking can be performed on this argument. Instead of
using container_of() like other callback subsystems, it forces callbacks
to do explicit type cast of the unsigned long argument into the required
object type.
- Buffer overflows can overwrite the .func and the .data field, so
an attacker can easily overwrite the function and its first argument
to whatever it wants.
Add a new tasklet initialization API, via DECLARE_TASKLET() and
tasklet_setup(), which will replace the existing ones.
This work is greatly inspired by the timer_struct conversion series,
see commit e99e88a9d2b0 ("treewide: setup_timer() -> timer_setup()")
To avoid problems with both -Wcast-function-type (which is enabled in
the kernel via -Wextra is several subsystems), and with mismatched
function prototypes when build with Control Flow Integrity enabled,
this adds the "use_callback" member to let the tasklet caller choose
which union member to call through. Once all old API uses are removed,
this and the .data member will be removed as well. (On 64-bit this does
not grow the struct size as the new member fills the hole after atomic_t,
which is also "int" sized.)

[ Upstream commit 90b7f2961798793275b4844348619b622f983907 ]
Syzkaller reports [1] encountering a common issue of utilizing a wrong
usb endpoint type during URB submitting stage. This, in turn, triggers
a warning shown below.
For now, enable simple endpoint checking (specifically, bulk and
interrupt eps, testing control one is not essential) to mitigate
the issue with a view to do other related cosmetic changes later,
if they are necessary.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hardik Gajjar <hgajjar@de.adit-jv.com>
[ Upstream commit a769154c7cac037914ba375ae88aae55b2c853e0 ]
- The HCD address_device callback now accepts a user-defined timeout value
in milliseconds, providing better control over command execution times.
- The default timeout value for the address_device command has been set
to 5000 ms, aligning with the USB 3.2 specification. However, this
timeout can be adjusted as needed.
- The xhci_setup_device function has been updated to accept the timeout
value, allowing it to specify the maximum wait time for the command
operation to complete.
- The hub driver has also been updated to accommodate the newly added
timeout parameter during the SET_ADDRESS request.

------------------
From: Michal Pecio <michal.pecio@gmail.com>
[ Upstream commit 1e0a19912adb68a4b2b74fd77001c96cd83eb073 ]
If a command is queued to the final usable TRB of a ring segment, the
enqueue pointer is advanced to the subsequent link TRB and no further.
If the command is later aborted, when the abort completion is handled
the dequeue pointer is advanced to the first TRB of the next segment.
If no further commands are queued, xhci_handle_stopped_cmd_ring() sees
the ring pointers unequal and assumes that there is a pending command,
so it calls xhci_mod_cmd_timer() which crashes if cur_cmd was NULL.
Don't attempt timer setup if cur_cmd is NULL. The subsequent doorbell
ring likely is unnecessary too, but it's harmless. Leave it alone.
This is probably Bug 219532, but no confirmation has been received.
The issue has been independently reproduced and confirmed fixed using
a USB MCU programmed to NAK the Status stage of SET_ADDRESS forever.
Everything continued working normally after several prevented crashes.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Daniel Wagner <wagi@kernel.org>
[ Upstream commit 294b2b7516fd06a8dd82e4a6118f318ec521e706 ]
When the set feature attempts fails with any NVME status code set in
nvme_set_queue_count, the function still report success. Though the
numbers of queues set to 0. This is done to support controllers in
degraded state (the admin queue is still up and running but no IO
queues).
Though there is an exception. When nvme_set_features reports an host
path error, nvme_set_queue_count should propagate this error as the
connectivity is lost, which means also the admin queue is not working
anymore.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hans Verkuil <hverkuil@xs4all.nl>
[ Upstream commit 6daaae5ff7f3b23a2dacc9c387ff3d4f95b67cad ]
If the hotplug detect of a display is low for longer than one second
(configurable through drm_dp_cec_unregister_delay), then the CEC adapter
is unregistered since we assume the display was disconnected. If the
HPD went low for less than one second, then we check if the properties
of the CEC adapter have changed, since that indicates that we actually
switch to new hardware and we have to unregister the old CEC device and
register a new one.
Unfortunately, the test for changed properties was written poorly, and
after a new CEC capability was added to the CEC core code the test always
returned true (i.e. the properties had changed).
As a result the CEC device was unregistered and re-registered for every
HPD toggle. If the CEC remote controller integration was also enabled
(CONFIG_MEDIA_CEC_RC was set), then the corresponding input device was
also unregistered and re-registered. As a result the input device in
/sys would keep incrementing its number, e.g.:
/sys/devices/pci0000:00/0000:00:08.1/0000:e7:00.0/rc/rc0/input20
Since short HPD toggles are common, the number could over time get into
the thousands.
While not a serious issue (i.e. nothing crashes), it is not intended
to work that way.
This patch changes the test so that it only checks for the single CEC
capability that can actually change, and it ignores any other
capabilities, so this is now safe as well if new caps are added in
the future.
With the changed test the bit under #ifndef CONFIG_MEDIA_CEC_RC can be
dropped as well, so that's a nice cleanup.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lenny Szubowicz <lszubowi@redhat.com>
[ Upstream commit e0efe83ed325277bb70f9435d4d9fc70bebdcca8 ]
Disable PCIe AER on the tg3 device on system reboot on a limited
list of Dell PowerEdge systems. This prevents a fatal PCIe AER event
on the tg3 device during the ACPI _PTS (prepare to sleep) method for
S5 on those systems. The _PTS is invoked by acpi_enter_sleep_state_prep()
as part of the kernel's reboot sequence as a result of commit
38f34dba806a ("PM: ACPI: reboot: Reinstate S5 for reboot").
There was an earlier fix for this problem by commit 2ca1c94ce0b6
("tg3: Disable tg3 device on system reboot to avoid triggering AER").
But it was discovered that this earlier fix caused a reboot hang
when some Dell PowerEdge servers were booted via ipxe. To address
this reboot hang, the earlier fix was essentially reverted by commit
9fc3bc764334 ("tg3: power down device only on SYSTEM_POWER_OFF").
This re-exposed the tg3 PCIe AER on reboot problem.
This fix is not an ideal solution because the root cause of the AER
is in system firmware. Instead, it's a targeted work-around in the
tg3 driver.
Note also that the PCIe AER must be disabled on the tg3 device even
if the system is configured to use "firmware first" error handling.
V3:
- Fix sparse warning on improper comparison of pdev->current_state
- Adhere to netdev comment style

[ Upstream commit 235174b2bed88501fda689c113c55737f99332d8 ]
Commit 4094871db1d6 ("udp: only do GSO if # of segs > 1") avoided GSO
for small packets. But the kernel currently dismisses GSO requests only
after checking MTU/PMTU on gso_size. This means any packets, regardless
of their payload sizes, could be dropped when PMTU becomes smaller than
requested gso_size. We encountered this issue in production and it
caused a reliability problem that new QUIC connection cannot be
established before PMTU cache expired, while non GSO sockets still
worked fine at the same time.
Ideally, do not check any GSO related constraints when payload size is
smaller than requested gso_size, and return EMSGSIZE instead of EINVAL
on MTU/PMTU check failure to be more specific on the error cause.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Dumazet <edumazet@google.com>
[ Upstream commit a1300691aed9ee852b0a9192e29e2bdc2411a7e6 ]
syzbot reported a soft lockup in rose_loopback_timer(),
with a repro calling bind() from multiple threads.
rose_bind() must lock the socket to avoid this issue.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")

------------------
From: Cong Wang <cong.wang@bytedance.com>
[ Upstream commit 638ba5089324796c2ee49af10427459c2de35f71 ]
qdisc_tree_reduce_backlog() notifies parent qdisc only if child
qdisc becomes empty, therefore we need to reduce the backlog of the
child qdisc before calling it. Otherwise it would miss the opportunity
to call cops->qlen_notify(), in the case of DRR, it resulted in UAF
since DRR uses ->qlen_notify() to maintain its active list.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Willem de Bruijn <willemb@google.com>
[ Upstream commit a70c7b3cbc0688016810bb2e0b9b8a0d6a530045 ]
This reverts commit 3ca459eaba1bf96a8c7878de84fa8872259a01e3.
The blamed commit caused a regression when neither tun->owner nor
tun->group is set. This is intended to be allowed, but now requires
CAP_NET_ADMIN.
Discussion in the referenced thread pointed out that the original
issue that prompted this patch can be resolved in userspace.
The relaxed access control may also make a device accessible when it
previously wasn't, while existing users may depend on it to not be.
This is a clean pure git revert, except for fixing the indentation on
the gid_valid line that checkpatch correctly flagged.

written. Drop the unexplainable division and write full ARRAY_SIZE().

From: Heiko Carstens <hca@linux.ibm.com>
commit 26701574cee6777f867f89b4a5c667817e1ee0dd upstream.
The futex operation FUTEX_OP_ANDN is supposed to implement
*(int *)UADDR2 &= ~OPARG;
The s390 implementation just implements an AND instead of ANDN.
Add the missing bitwise not operation to oparg to fix this.
This is broken since nearly 19 years, so it looks like user space is
not making use of this operation.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@linaro.org>
commit 55cf2f4b945f6a6416cc2524ba740b83cc9af25a upstream.
Most of these sizes and counts are capped at 256MB so the math doesn't
result in an integer overflow. The "relocs" count needs to be checked
as well. Otherwise on 32bit systems the calculation of "full_data"
could be wrong.
full_data = data_len + relocs * sizeof(unsigned long);

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jakob Unterwurzacher <jakobunt@gmail.com>
commit 9d241b06802c6c2176ae7aa4f9f17f8a577ed337 upstream.
During mass manufacturing, we noticed the mmc_rx_crc_error counter,
as reported by "ethtool -S eth0 | grep mmc_rx_crc_error", to increase
above zero during nuttcp speedtests. Most of the time, this did not
affect the achieved speed, but it prompted this investigation.
Cycling through the rx_delay range on six boards (see table below) of
various ages shows that there is a large good region from 0x12 to 0x35
where we see zero crc errors on all tested boards.
The old rx_delay value (0x10) seems to have always been on the edge for
the KSZ9031RNX that is usually placed on Puma.
Choose "rx_delay = 0x23" to put us smack in the middle of the good
region. This works fine as well with the KSZ9131RNX PHY that was used
for a small number of boards during the COVID chip shortages.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sean Christopherson <seanjc@google.com>
commit 1e7381f3617d14b3c11da80ff5f8a93ab14cfc46 upstream.
Explicitly verify the target vCPU is fully online _prior_ to clamping the
index in kvm_get_vcpu(). If the index is "bad", the nospec clamping will
generate '0', i.e. KVM will return vCPU0 instead of NULL.
In practice, the bug is unlikely to cause problems, as it will only come
into play if userspace or the guest is buggy or misbehaving, e.g. KVM may
send interrupts to vCPU0 instead of dropping them on the floor.
However, returning vCPU0 when it shouldn't exist per online_vcpus is
problematic now that KVM uses an xarray for the vCPUs array, as KVM needs
to insert into the xarray before publishing the vCPU to userspace (see
commit c5b077549136 ("KVM: Convert the kvm->vcpus array to a xarray")),
i.e. before vCPU creation is guaranteed to succeed.
As a result, incorrectly providing access to vCPU0 will trigger a
use-after-free if vCPU0 is dereferenced and kvm_vm_ioctl_create_vcpu()
bails out of vCPU creation due to an error and frees vCPU0. Commit
afb2acb2e3a3 ("KVM: Fix vcpu_array[0] races") papered over that issue, but
in doing so introduced an unsolvable teardown conundrum. Preventing
accesses to vCPU0 before it's fully online will allow reverting commit
afb2acb2e3a3, without re-introducing the vcpu_array[0] UAF race.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Hildenbrand <david@redhat.com>
commit 5f230f41fdd9e799f43a699348dc572bca7159aa upstream.
We try to reuse the same vsie page when re-executing the vsie with a
given SCB address. The result is that we use the same shadow SCB --
residing in the vsie page -- and can avoid flushing the TLB when
re-running the vsie on a CPU.
So, when we allocate a fresh vsie page, or when we reuse a vsie page for
a different SCB address -- reusing the shadow SCB in different context --
we set ihcpu=0xffff to trigger the flush.
However, after we looked up the SCB address in the radix tree, but before
we grabbed the vsie page by raising the refcount to 2, someone could reuse
the vsie page for a different SCB address, adjusting page->index and the
radix tree. In that case, we would be reusing the vsie page with a
wrong page->index.
Another corner case is that we might set the SCB address for a vsie
page, but fail the insertion into the radix tree. Whoever would reuse
that page would remove the corresponding radix tree entry -- which might
now be a valid entry pointing at another page, resulting in the wrong
vsie page getting removed from the radix tree.
Let's handle such races better, by validating that the SCB address of a
vsie page didn't change after we grabbed it (not reuse for a different
SCB; the alternative would be performing another tree lookup), and by
setting the SCB address to invalid until the insertion in the tree
succeeded (SCB addresses are aligned to 512, so ULONG_MAX is invalid).
These scenarios are rare, the effects a bit unclear, and these issues were
only found by code inspection. Let's CC stable to be safe.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Fedor Pchelkin <pchelkin@ispras.ru>
commit 5f397409f8ee5bc82901eeaf799e1cbc4f8edcf1 upstream.
A NULL sock pointer is passed into l2cap_sock_alloc() when it is called
from l2cap_sock_new_connection_cb() and the error handling paths should
also be aware of it.
Seemingly a more elegant solution would be to swap bt_sock_alloc() and
l2cap_chan_create() calls since they are not interdependent to that moment
but then l2cap_chan_create() adds the soon to be deallocated and still
dummy-initialized channel to the global list accessible by many L2CAP
paths. The channel would be removed from the list in short period of time
but be a bit more straight-forward here and just check for NULL instead of
changing the order of function calls.
Found by Linux Verification Center (linuxtesting.org) with SVACE static
analysis tool.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gabor Juhos <j4g8y7@gmail.com>
commit 33f1722eb86e45320a3dd7b3d42f6593a1d595c2 upstream.
Commit c45ae598fc16 ("clk: qcom: support for alpha mode configuration")
added support for configuring alpha mode, but it seems that the feature
was never working in practice.
The value of the alpha_{en,mode}_mask members of the configuration gets
added to the value parameter passed to the regmap_update_bits() function,
however the same values are not getting applied to the bitmask. As the
result, the respective bits in the USER_CTL register are never modifed
which leads to improper configuration of several PLLs.
The following table shows the PLL configurations where the 'alpha_en_mask'
member is set and which are passed as a parameter for the
clk_alpha_pll_configure() function. In the table the 'expected rate' column
shows the rate the PLL should run at with the given configuration, and
the 'real rate' column shows the rate the PLL runs at actually. The real
rates has been verified on hardwareOn IPQ* platforms, on other platforms,
those are computed values only.

gpucc-sm6125.c gpu_pll1 930.0 MHz != 921.6 MHz
mmcc-sdm660.c mmpll8 930.0 MHz != 921.6 MHz
mmcc-sdm660.c mmpll5 825.0 MHz != 806.4 MHz
As it can be seen from the above, there are several PLLs which are
configured incorrectly.
Change the code to apply both 'alpha_en_mask' and 'alpha_mode_mask'
values to the bitmask in order to configure the alpha mode correctly.
Applying the 'alpha_en_mask' fixes the initial rate of the PLLs showed
in the table above. Since the 'alpha_mode_mask' is not used by any driver
currently, that part of the change causes no functional changes.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kuan-Wei Chiu <visitorckw@gmail.com>
commit 62892e77b8a64b9dc0e1da75980aa145347b6820 upstream.
The comparison function cmpworker() violates the C standard's
requirements for qsort() comparison functions, which mandate symmetry
and transitivity:
Symmetry: If x < y, then y > x.
Transitivity: If x < y and y < z, then x < z.
In its current implementation, cmpworker() incorrectly returns 0 when
w1->tid < w2->tid, which breaks both symmetry and transitivity. This
violation causes undefined behavior, potentially leading to issues such
as memory corruption in glibc [1].
Fix the issue by returning -1 when w1->tid < w2->tid, ensuring
compliance with the C standard and preventing undefined behavior.

commit e4c00c9b1f70cd11792ff5b825899a6ee0234a62 upstream.
API of_parse_phandle_with_args_map() will use wrong input for nexus node
Nexus_2 as shown below:
Node_1 Nexus_1 Nexus_2
&Nexus_1,arg_1 -> arg_1,&Nexus_2,arg_2' -> &Nexus_2,arg_2 -> arg_2,...
map-pass-thru=<...>
Nexus_1's output arg_2 should be used as input of Nexus_2, but the API
wrongly uses arg_2' instead which != arg_2 due to Nexus_1's map-pass-thru.
Fix by always making @match_array point to @initial_match_array into
which to store nexus output.

of_find_node_opts_by_path() fails to find OF device node when its
@path parameter have pattern below:
"alias-name/node-name-1/.../node-name-N:options".
The reason is that alias name length calculated by the API is wrong, as
explained by example below:
"testcase-alias/phandle-tests/consumer-a:testaliasoption".
^ ^ ^
0 14 39
The right length of alias 'testcase-alias' is 14, but the result worked
out by the API is 39 which is obvious wrong.
Fix by using index of either '/' or ':' as the length who comes earlier.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Heiko Stuebner <heiko@sntech.de>
commit 8a5b38c3fd709e8acd2bfdedf66c25e6af759576 upstream.
The hid-sensor-hub creates the individual device structs and transfers them
to the created mfd platform-devices via the platform_data in the mfd_cell.
Before e651a1da442a ("HID: hid-sensor-hub: Allow parallel synchronous reads")
the sensor-hub was managing access centrally, with one "completion" in the
hub's data structure, which needed to be finished on removal at the latest.
The mentioned commit then moved this central management to each hid sensor
device, resulting on a completion in each struct hid_sensor_hub_device.
The remove procedure was adapted to go through all sensor devices and
finish any pending "completion".
What this didn't take into account was, platform_device_add_data() that is
used by mfd_add{_hotplug}_devices() does a kmemdup on the submitted
platform-data. So the data the platform-device gets is a copy of the
original data, meaning that the device worked on a different completion
than what sensor_hub_remove() currently wants to access.
To fix that, use device_for_each_child() to go through each child-device
similar to how mfd_remove_devices() unregisters the devices later and
with that get the live platform_data to finalize the correct completion.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marcel Hamer <marcel.hamer@windriver.com>
commit 68abd0c4ebf24cd499841a488b97a6873d5efabb upstream.
On removal of the device or unloading of the kernel module a potential NULL
pointer dereference occurs.
The following sequence deletes the interface:
brcmf_detach()
brcmf_remove_interface()
brcmf_del_if()
Inside the brcmf_del_if() function the drvr->if2bss[ifidx] is updated to
BRCMF_BSSIDX_INVALID (-1) if the bsscfgidx matches.
After brcmf_remove_interface() call the brcmf_proto_detach() function is
called providing the following sequence:
brcmf_detach()
brcmf_proto_detach()
brcmf_proto_msgbuf_detach()
brcmf_flowring_detach()
brcmf_msgbuf_delete_flowring()
brcmf_msgbuf_remove_flowring()
brcmf_flowring_delete()
brcmf_get_ifp()
brcmf_txfinalize()
Since brcmf_get_ip() can and actually will return NULL in this case the
call to brcmf_txfinalize() will result in a NULL pointer dereference inside
brcmf_txfinalize() when trying to update ifp->ndev->stats.tx_errors.
This will only happen if a flowring still has an skb.
Although the NULL pointer dereference has only been seen when trying to
update the tx statistic, all other uses of the ifp pointer have been
guarded as well with an early return if ifp is NULL.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Stephan Gerhold <stephan.gerhold@linaro.org>
commit 22cf4fae6660b6e1a583a41cbf84e3046ca9ccd0 upstream.
On MSM8916 devices, the serial number exposed in sysfs is constant and does
not change across individual devices. It's always:
db410c:/sys/devices/soc0$ cat serial_number
2644893864
The firmware used on MSM8916 exposes SOCINFO_VERSION(0, 8), which does not
have support for the serial_num field in the socinfo struct. There is an
existing check to avoid exposing the serial number in that case, but it's
not correct: When checking the item_size returned by SMEM, we need to make
sure the *end* of the serial_num is within bounds, instead of comparing
with the *start* offset. The serial_number currently exposed on MSM8916
devices is just an out of bounds read of whatever comes after the socinfo
struct in SMEM.
Fix this by changing offsetof() to offsetofend(), so that the size of the
field is also taken into account.

commit eaeee4225dba30bef4d424bdf134a07b7f423e8b upstream.
The port_cfg object is used by serial_console_write(), which serves as
the write function for the earlycon device. Marking port_cfg as __initdata
causes it to be freed after kernel initialization, resulting in earlycon
becoming unavailable thereafter. Remove the __initdata macro from port_cfg
to resolve this issue.

In the sh-sci driver, sci_ports[0] is used by earlycon. If the earlycon is
still active when sci_probe() is called and the new serial port is supposed
to map to sci_ports[0], return -EBUSY to prevent breaking the earlycon.
This situation should occurs in debug scenarios, and users should be

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Narayana Murty N <nnmlinux@linux.ibm.com>
commit 11b93559000c686ad7e5ab0547e76f21cc143844 upstream.
The PE Reset State "0" returned by RTAS calls
"ibm_read_slot_reset_[state|state2]" indicates that the reset is
deactivated and the PE is in a state where MMIO and DMA are allowed.
However, the current implementation of "pseries_eeh_get_state()" does
not reflect this, causing drivers to incorrectly assume that MMIO and
DMA operations cannot be resumed.
The userspace drivers as a part of EEH recovery using VFIO ioctls fail
to detect when the recovery process is complete. The VFIO_EEH_PE_GET_STATE
ioctl does not report the expected EEH_PE_STATE_NORMAL state, preventing
userspace drivers from functioning properly on pseries systems.
The patch addresses this issue by updating 'pseries_eeh_get_state()'
to include "EEH_STATE_MMIO_ENABLED" and "EEH_STATE_DMA_ENABLED" in
the result mask for PE Reset State "0". This ensures correct state
reporting to the callers, aligning the behavior with the PAPR specification
and fixing the bug in EEH recovery for VFIO user workflows.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nathan Chancellor <nathan@kernel.org>
commit 8f6629c004b193d23612641c3607e785819e97ab upstream.
-Wenum-enum-conversion was strengthened in clang-19 to warn for C, which
caused the kernel to move it to W=1 in commit 75b5ab134bb5 ("kbuild:
Move -Wenum-{compare-conditional,enum-conversion} into W=1") because
there were numerous instances that would break builds with -Werror.
Unfortunately, this is not a full solution, as more and more developers,
subsystems, and distributors are building with W=1 as well, so they
continue to see the numerous instances of this warning.
Since the move to W=1, there have not been many new instances that have
appeared through various build reports and the ones that have appeared
seem to be following similar existing patterns, suggesting that most
instances of this warning will not be real issues. The only alternatives
for silencing this warning are adding casts (which is generally seen as
an ugly practice) or refactoring the enums to macro defines or a unified
enum (which may be undesirable because of type safety in other parts of
the code).
Move the warning to W=2, where warnings that occur frequently but may be
relevant should reside.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jennifer Berringer <jberring@redhat.com>
commit 31507fc2ad36e0071751a710449db19c85d82a7f upstream.
When __nvmem_cell_entry_write() is called for an nvmem cell that does
not need bit shifting, it requires that the len parameter exactly
matches the nvmem cell size. However, when the nvmem cell has a nonzero
bit_offset, it was skipping this check.
Accepting values of len larger than the cell size results in
nvmem_cell_prepare_write_buffer() trying to write past the end of a heap
buffer that it allocates. Add a check to avoid that problem and instead
return -EINVAL when len doesn't match the number of bits expected by the
nvmem cell when bit_offset is nonzero.
This check uses cell->nbits in order to allow providing the smaller size
to cells that are shifted into another byte by bit_offset. For example,
a cell with nbits=8 and nonzero bit_offset would have bytes=2 but should
accept a 1-byte write here, although no current callers depend on this.

commit 2b4c2094da6d84e69b843dd3317902e977bf64bd upstream.
Patch series "Convert ocfs2 to use folios".
Mark did a conversion of ocfs2 to use folios and sent it to me as a
giant patch for review ;-)
So I've redone it as individual patches, and credited Mark for the patches
where his code is substantially the same. It's not a bad way to do it;
his patch had some bugs and my patches had some bugs. Hopefully all our
bugs were different from each other. And hopefully Mark likes all the
changes I made to his code!

From: Nikita Zhandarovich <n.zhandarovich@fintech.ru>
commit 6438ef381c183444f7f9d1de18f22661cba1e946 upstream.
Since nilfs_bmap_lookup_contig() in nilfs_fiemap() calculates its result
by being prepared to go through potentially maxblocks == INT_MAX blocks,
the value in n may experience an overflow caused by left shift of blkbits.
While it is extremely unlikely to occur, play it safe and cast right hand
expression to wider type to mitigate the issue.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ekansh Gupta <quic_ekangupt@quicinc.com>
commit 6ca4ea1f88a06a04ed7b2c9c6bf9f00833b68214 upstream.
For registered buffers, fastrpc driver sends the buffer information
to remote subsystem. There is a problem with current implementation
where the page address is being sent with an offset leading to
improper buffer address on DSP. This is leads to functional failures
as DSP expects base address in page information and extracts offset
information from remote arguments. Mask the offset and pass the base
page address to DSP.
This issue is observed is a corner case when some buffer which is registered
with fastrpc framework is passed with some offset by user and then the DSP
implementation tried to read the data. As DSP expects base address and takes
care of offsetting with remote arguments, passing an offsetted address will
result in some unexpected data read in DSP.
All generic usecases usually pass the buffer as it is hence is problem is
not usually observed. If someone tries to pass offsetted buffer and then
tries to compare data at HLOS and DSP end, then the ambiguity will be observed.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Paul Fertser <fercerpav@gmail.com>
commit 6bb194d036c6e1b329dcdff459338cdd9a54802a upstream.
The NCSI state machine as it's currently implemented assumes that
transition to the next logical state is performed either explicitly by
calling `schedule_work(&ndp->work)` to re-queue itself or implicitly
after processing the predefined (ndp->pending_req_num) number of
replies. Thus to avoid the configuration FSM from advancing prematurely
and getting out of sync with the process it's essential to not skip
waiting for a reply.
This patch makes the code wait for reception of the Deselect Package
response for the last package probed before proceeding to channel
configuration.
Thanks go to Potin Lai and Cosmo Chou for the initial investigation and
testing.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Weißschuh <linux@weissschuh.net>
commit fd53aa40e65f518453115b6f56183b0c201db26b upstream.
The ioctl and sysfs handlers unconditionally call the ->enable callback.
Not all drivers implement that callback, leading to NULL dereferences.
Example of affected drivers: ptp_s390.c, ptp_vclock.c and ptp_mock.c.
Instead use a dummy callback if no better was specified by the driver.
Fixes: d94ba80ebbea ("ptp: Added a brand new class driver for ptp clocks.")

The two reports are all caused invalid negative i_size of dir inode. For
ocfs2, dir_inode can't be negative or zero.
Here add a check in which is called by ocfs2_check_dir_for_entry(). It
fixes the second report as ocfs2_check_dir_for_entry() must be called
before ocfs2_prepare_dir_for_insert(). Also set a up limit for dir with
OCFS2_INLINE_DATA_FL. The i_size can't be great than blocksize.

5.4-stable review patch. If anyone has any objections, please let me know.

From: Charles Han <hanchunchao@inspur.com>
[ Upstream commit 9b8e2220d3a052a690b1d1b23019673e612494c5 ]
devm_kasprintf() can return a NULL pointer on failure,but this
returned value in mt_input_configured() is not checked.
Add NULL check in mt_input_configured(), to handle kernel NULL
pointer dereference error.

check on the array size but does not account for cache levels with

------------------
From: Artur Weber <aweber.kernel@gmail.com>
[ Upstream commit de1d0d160f64ee76df1d364d521b2faf465a091c ]
The GPIO lock/unlock functions clear/write a bit to the relevant
register for each bank. However, due to an oversight the bit that
was being written was based on the total GPIO number, not the index
of the GPIO within the relevant bank, causing it to fail for any
GPIO above 32 (thus any GPIO for banks above bank 0).
Fix lock/unlock for these banks by using the correct bit.

From: Artur Weber <aweber.kernel@gmail.com>
[ Upstream commit 57f5db77a915cc29461a679a6bcae7097967be1a ]
The settings for all GPIOs are locked by default in bcm_kona_gpio_reset.
The settings for a GPIO are unlocked when requesting it as a GPIO, but
not when requesting it as an interrupt, causing the IRQ settings to not
get applied.
Fix this by making sure to unlock the right bits when an IRQ is requested.
To avoid a situation where an IRQ being released causes a lock despite
the same GPIO being used by a GPIO request or vice versa, add an unlock
counter and only lock if it reaches 0.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Juergen Gross <jgross@suse.com>
[ Upstream commit e93ec87286bd1fd30b7389e7a387cfb259f297e3 ]
Today a PV guest (including dom0) can create 2MB contiguous memory
regions for DMA buffers at max. This has led to problems at least
with the megaraid_sas driver, which wants to allocate a 2.3MB DMA
buffer.
The limiting factor is the frame array used to do the hypercall for
making the memory contiguous, which has 512 entries and is just a
static array in mmu_pv.c.
In order to not waste memory for non-PV guests, put the initial
frame array into .init.data section and dynamically allocate an array
from the .init_after_bootmem hook of PV guests.
In case a contiguous memory area larger than the initially supported
2MB is requested, allocate a larger buffer for the frame list. Note
that such an allocation is tried only after memory management has been
initialized properly, which is tested via a flag being set in the
.init_after_bootmem hook.

From: Arnd Bergmann <arnd@arndb.de>
[ Upstream commit 8d46603eeeb4c6abff1d2e49f2a6ae289dac765e ]
It appears that do_div() once more gets confused by a complex
expression that ends up not quite being constant despite
__builtin_constant_p() thinking it is:
ERROR: modpost: "__aeabi_uldivmod" [drivers/media/dvb-frontends/cxd2841er.ko] undefined!
Use div_u64() instead, forcing the expression to be evaluated
first, and making it a bit more readable.

[ Upstream commit 2b938e3db335e3670475e31a722c2bee34748c5a ]
Definitions of ioread64 and iowrite64 macros in asm/io.h called by vfio
pci implementations are enclosed inside check for CONFIG_GENERIC_IOMAP.
They don't get defined if CONFIG_GENERIC_IOMAP is defined. Include
linux/io-64-nonatomic-lo-hi.h to define iowrite64 and ioread64 macros
when they are not defined. io-64-nonatomic-lo-hi.h maps the macros to
generic implementation in lib/iomap.c. The generic implementation does
64 bit rw if readq/writeq is defined for the architecture, otherwise it
would do 32 bit back to back rw.
Note that there are two versions of the generic implementation that
differs in the order the 32 bit words are written if 64 bit support is
not present. This is not the little/big endian ordering, which is
handled separately. This patch uses the lo followed by hi word ordering
which is consistent with current back to back implementation in the
vfio/pci code.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Maksym Planeta <maksym@exostellar.io>
[ Upstream commit 6d002348789bc16e9203e9818b7a3688787e3b29 ]
Function xen_pin_page calls xen_pte_lock, which in turn grab page
table lock (ptlock). When locking, xen_pte_lock expect mm->page_table_lock
to be held before grabbing ptlock, but this does not happen when pinning
is caused by xen_mm_pin_all.
This commit addresses lockdep warning below, which shows up when
suspending a Xen VM.

From: Hans de Goede <hdegoede@redhat.com>
[ Upstream commit 6917192378c1ce17ba31df51c4e0d8b1c97a453b ]
The Vexia EDU ATLA 10 tablet comes in 2 different versions with
significantly different mainboards. The only outward difference is that
the charging barrel on one is marked 5V and the other is marked 9V.
The 5V version mostly works with the BYTCR defaults, except that it is
missing a CHAN package in its ACPI tables and the default of using
SSP0-AIF2 is wrong, instead SSP0-AIF1 must be used. That and its jack
detect signal is not inverted as it usually is.
Add a DMI quirk for the 5V version to fix sound not working.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andy Strohman <andrew@andrewstrohman.com>
commit ccb7276a6d26d6f8416e315b43b45e15ee7f29e2 upstream.
Reference counting is used to ensure that
batadv_hardif_neigh_node and batadv_hard_iface
are not freed before/during
batadv_v_elp_throughput_metric_update work is
finished.
But there isn't a guarantee that the hard if will
remain associated with a soft interface up until
the work is finished.
This fixes a crash triggered by reboot that looks
like this:
Call trace:
batadv_v_mesh_free+0xd0/0x4dc [batman_adv]
batadv_v_elp_throughput_metric_update+0x1c/0xa4
process_one_work+0x178/0x398
worker_thread+0x2e8/0x4d0
kthread+0xd8/0xdc
ret_from_fork+0x10/0x20
(the batadv_v_mesh_free call is misleading,
and does not actually happen)
I was able to make the issue happen more reliably
by changing hardif_neigh->bat_v.metric_work work
to be delayed work. This allowed me to track down
and confirm the fix.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Elson Roy Serrao <quic_eserrao@quicinc.com>
commit 634775a752a86784511018a108f3b530cc3399a7 upstream.
The role switch registration and set_role() can happen in parallel as they
are invoked independent of each other. There is a possibility that a driver
might spend significant amount of time in usb_role_switch_register() API
due to the presence of time intensive operations like component_add()
which operate under common mutex. This leads to a time window after
allocating the switch and before setting the registered flag where the set
role notifications are dropped. Below timeline summarizes this behavior
Thread1 | Thread2
usb_role_switch_register() |
| |
---> allocate switch |
| |
---> component_add() | usb_role_switch_set_role()
| | |
| | --> Drop role notifications
| | since sw->registered
| | flag is not set.
| |
--->Set registered flag.|
To avoid this, set the registered flag early on in the switch register
API.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Fabrice Gasnier <fabrice.gasnier@foss.st.com>
commit 58cd423820d5b5610977e55e4acdd06628829ede upstream.
In dwc2_hsotg_udc_start(), e.g. when binding composite driver, "of_node"
is set to hsotg->dev->of_node.
It causes errors when binding the gadget driver several times, on
stm32mp157c-ev1 board. Below error is seen:
"pin PA10 already requested by 49000000.usb-otg; cannot claim for gadget.0"
The first time, no issue is seen as when registering the driver, of_node
isn't NULL:
-> gadget_dev_desc_UDC_store
-> usb_gadget_register_driver_owner
-> driver_register
...
-> really_probe -> pinctrl_bind_pins (no effect)
Then dwc2_hsotg_udc_start() sets of_node.
The second time (stop the gadget, reconfigure it, then start it again),
of_node has been set, so the probing code tries to acquire pins for the
gadget. These pins are hold by the controller, hence the error.
So clear gadget.dev.of_node in udc_stop() routine to avoid the issue.

LS7A EHCI controller doesn't have extended capabilities, so the EECP

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mathias Nyman <mathias.nyman@linux.intel.com>
commit 159daf1258227f44b26b5d38f4aa8f37b8cca663 upstream.
The fastboot tool for communicating with Android bootloaders does not
work reliably with this device if USB 2 Link Power Management (LPM)
is enabled.
Various fastboot commands are affected, including the
following, which usually reproduces the problem within two tries:
fastboot getvar kernel
getvar:kernel FAILED (remote: 'GetVar Variable Not found')
This issue was hidden on many systems up until commit 63a1f8454962
("xhci: stored cached port capability values in one place") as the xhci
driver failed to detect USB 2 LPM support if USB 3 ports were listed
before USB 2 ports in the "supported protocol capabilities".
Adding the quirk resolves the issue. No drawbacks are expected since
the device uses different USB product IDs outside of fastboot mode, and
since fastboot commands worked before, until LPM was enabled on the
tested system by the aforementioned commit.
Based on a patch from Forest <forestix@nom.one> from which most of the
code and commit message is taken.

From: John Keeping <jkeeping@inmusicbrands.com>
commit da1668997052ed1cb00322e1f3b63702615c9429 upstream.
While the MIDI jacks are configured correctly, and the MIDIStreaming
endpoint descriptors are filled with the correct information,
bNumEmbMIDIJack and bLength are set incorrectly in these descriptors.
This does not matter when the numbers of in and out ports are equal, but
when they differ the host will receive broken descriptors with
uninitialized stack memory leaking into the descriptor for whichever
value is smaller.
The precise meaning of "in" and "out" in the port counts is not clearly
defined and can be confusing. But elsewhere the driver consistently
uses this to match the USB meaning of IN and OUT viewed from the host,
so that "in" ports send data to the host and "out" ports receive data
from it.

The cause of this error is that the device has two interfaces, and the
hub driver binds to interface 1 instead of interface 0, which is where
usb_hub_to_struct_hub() looks.
We can prevent the problem from occurring by refusing to accept hub
devices that violate the USB spec by having more than one
configuration or interface.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jann Horn <jannh@google.com>
commit e563b01208f4d1f609bcab13333b6c0e24ce6a01 upstream.
If the first fragment is shorter than struct usb_cdc_notification, we can't
calculate an expected_size. Log an error and discard the notification
instead of reading lengths from memory outside the received data, which can
lead to memory corruption when the expected_size decreases between
fragments, causing `expected_size - acm->nb_index` to wrap.
This issue has been present since the beginning of git history; however,
it only leads to memory corruption since commit ea2583529cd1
("cdc-acm: reassemble fragmented notifications").
A mitigating factor is that acm_ctrl_irq() can only execute after userspace
has opened /dev/ttyACM*; but if ModemManager is running, ModemManager will
do that automatically depending on the USB device's vendor/product IDs and
its other interfaces.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jann Horn <jannh@google.com>
commit 12e712964f41d05ae034989892de445781c46730 upstream.
If we receive an initial fragment of size 8 bytes which specifies a wLength
of 1 byte (so the reassembled message is supposed to be 9 bytes long), and
we then receive a second fragment of size 9 bytes (which is not supposed to
happen), we currently wrongly bypass the fragment reassembly code but still
pass the pointer to the acm->notification_buffer to
acm_process_notification().
Make this less wrong by always going through fragment reassembly when we
expect more fragments.
Before this patch, receiving an overlong fragment could lead to `newctrl`
in acm_process_notification() being uninitialized data (instead of data
coming from the device).

commit db79e75460fc59b19f9c89d4b068e61cee59f37d upstream.
MeiG Smart SLM828 is an LTE-A CAT6 modem with the mPCIe form factor. The
"Cls=ff(vend.) Sub=10 Prot=02" and "Cls=ff(vend.) Sub=10 Prot=03"
interfaces respond to AT commands. Add these interfaces.
The product ID the modem uses is shared across multiple modems. Therefore,
add comments to describe which interface is used for which modem.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Fabio Porcedda <fabio.porcedda@gmail.com>
commit 12606fe73f33647c5e79bf666833bf0b225e649d upstream.
The correct name for FN990 is FN990A so use it in order to avoid
confusion with FN990B.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold <johan@kernel.org>
commit 6aa8a63c471eb6756aabd03f880feffe6a7af6c9 upstream.
Several MeiG Smart modems apparently use the same product id, making the
defines even less useful.
Drop them in favour of using comments consistently to make the id table
slightly less unwieldy.

From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
commit 257a2cd3eb578ee63d6bf90475dc4f4b16984139 upstream.
Runtime PM is enabled as one of the last steps of probe(), so all
earlier gotos to "exit_free_device" label were not correct and were
leading to unbalanced runtime PM disable depth.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alexander Hölzl <alexander.hoelzl@gmx.net>
commit 44de577e61ed239db09f0da9d436866bef9b77dd upstream.
The J1939 standard requires the transmission of messages of length 0.
For example proprietary messages are specified with a data length of 0
to 1785. The transmission of such messages is not possible. Sending
results in no error being returned but no corresponding can frame
being generated.
Enable the transmission of zero length J1939 messages. In order to
facilitate this two changes are necessary:
1) If the transmission of a new message is requested from user space
the message is segmented in j1939_sk_send_loop(). Let the segmentation
take into account zero length messages, do not terminate immediately,
queue the corresponding skb.
2) j1939_session_skb_get_by_offset() selects the next skb to transmit
for a session. Take into account that there might be zero length skbs
in the queue.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ivan Kokshaysky <ink@unseen.parts>
commit 0a0f7362b0367634a2d5cb7c96226afc116f19c9 upstream.
The problem is that GCC expects 16-byte alignment of the incoming stack
since early 2004, as Maciej found out [1]:
Having actually dug speculatively I can see that the psABI was changed in
GCC 3.5 with commit e5e10fb4a350 ("re PR target/14539 (128-bit long double
improperly aligned)") back in Mar 2004, when the stack pointer alignment
was increased from 8 bytes to 16 bytes, and arch/alpha/kernel/entry.S has
various suspicious stack pointer adjustments, starting with SP_OFF which
is not a whole multiple of 16.
Also, as Magnus noted, "ALPHA Calling Standard" [2] required the same:
D.3.1 Stack Alignment
This standard requires that stacks be octaword aligned at the time a
new procedure is invoked.
However:
- the "normal" kernel stack is always misaligned by 8 bytes, thanks to
the odd number of 64-bit words in 'struct pt_regs', which is the very
first thing pushed onto the kernel thread stack;
- syscall, fault, interrupt etc. handlers may, or may not, receive aligned
stack depending on numerous factors.
Somehow we got away with it until recently, when we ended up with
a stack corruption in kernel/smp.c:smp_call_function_single() due to
its use of 32-byte aligned local data and the compiler doing clever
things allocating it on the stack.
This adds padding between the PAL-saved and kernel-saved registers
so that 'struct pt_regs' have an even number of 64-bit words.
This makes the stack properly aligned for most of the kernel
code, except two handlers which need special threatment.
Note: struct pt_regs doesn't belong in uapi/asm; this should be fixed,
but let's put this off until later.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: John Keeping <jkeeping@inmusicbrands.com>
commit 9e512eaaf8f4008c44ede3dfc0fbc9d9c5118583 upstream.
When flushing the serial port's buffer, uart_flush_buffer() calls
kfifo_reset() but if there is an outstanding DMA transfer then the
completion function will consume data from the kfifo via
uart_xmit_advance(), underflowing and leading to ongoing DMA as the
driver tries to transmit another 2^32 bytes.
This is readily reproduced with serial-generic and amidi sending even
short messages as closing the device on exit will wait for the fifo to
drain and in the underflow case amidi hangs for 30 seconds on exit in
tty_wait_until_sent(). A trace of that gives:
kworker/1:1-84 [001] 51.769423: bprint: serial8250_tx_dma: tx_size=3 fifo_len=3
amidi-763 [001] 51.769460: bprint: uart_flush_buffer: resetting fifo
irq/21-fe530000-76 [000] 51.769474: bprint: __dma_tx_complete: tx_size=3
irq/21-fe530000-76 [000] 51.769479: bprint: serial8250_tx_dma: tx_size=4096 fifo_len=4294967293
irq/21-fe530000-76 [000] 51.781295: bprint: __dma_tx_complete: tx_size=4096
irq/21-fe530000-76 [000] 51.781301: bprint: serial8250_tx_dma: tx_size=4096 fifo_len=4294963197
irq/21-fe530000-76 [000] 51.793131: bprint: __dma_tx_complete: tx_size=4096
irq/21-fe530000-76 [000] 51.793135: bprint: serial8250_tx_dma: tx_size=4096 fifo_len=4294959101
irq/21-fe530000-76 [000] 51.804949: bprint: __dma_tx_complete: tx_size=4096
Since the port lock is held in when the kfifo is reset in
uart_flush_buffer() and in __dma_tx_complete(), adding a flush_buffer
hook to adjust the outstanding DMA byte count is sufficient to avoid the
kfifo underflow.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wentao Liang <vulab@iscas.ac.cn>
commit b9644fbfbcab13da7f8b37bef7c51e5b8407d031 upstream.
The stmpe_reg_read function can fail, but its return value is not checked
in stmpe_gpio_irq_sync_unlock. This can lead to silent failures and
incorrect behavior if the hardware access fails.
This patch adds checks for the return value of stmpe_reg_read. If the
function fails, an error message is logged and the function returns
early to avoid further issues.
Fixes: b888fb6f2a27 ("gpio: stmpe: i2c transfer are forbiden in atomic context")

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jann Horn <jannh@google.com>
commit 80e648042e512d5a767da251d44132553fe04ae0 upstream.
Fix several issues in partition probing:
- The bailout for a bad partoffset must use put_dev_sector(), since the
preceding read_part_sector() succeeded.
- If the partition table claims a silly sector size like 0xfff bytes
(which results in partition table entries straddling sector boundaries),
bail out instead of accessing out-of-bounds memory.
- We must not assume that the partition table contains proper NUL
termination - use strnlen() and strncmp() instead of strlen() and
strcmp().

use rcu_read_lock() or RTNL.
We currently use a generic helper, dev_net() with

From: Li Zetao <lizetao1@huawei.com>
[ Upstream commit c25bdd2ac8cf7da70a226f1a66cdce7af15ff86f ]
The initial value of err is -ENOBUFS, and err is guaranteed to be
less than 0 before all goto errout. Therefore, on the error path
of errout, there is no need to repeatedly judge that err is less than 0,
and delete redundant judgments to make the code more concise.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ryusuke Konishi <konishi.ryusuke@gmail.com>
commit 299910dcb4525ac0274f3efa9527876315ba4f67 upstream.
After detecting file system corruption and degrading to a read-only mount,
dirty folios and buffers in the page cache are cleared, and a large number
of warnings are output at that time, often filling up the kernel log.
In this case, since the degrading to a read-only mount is output to the
kernel log, these warnings are not very meaningful, and are rather a
nuisance in system management and debugging.
The related nilfs2-specific page/folio routines have a silent argument
that suppresses the warning output, but since it is not currently used
meaningfully, remove both the silent argument and the warning output.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ryusuke Konishi <konishi.ryusuke@gmail.com>
commit ca76bb226bf47ff04c782cacbd299f12ddee1ec1 upstream.
Patch series "nilfs2: protect busy buffer heads from being force-cleared".
This series fixes the buffer head state inconsistency issues reported by
syzbot that occurs when the filesystem is corrupted and falls back to
read-only, and the associated buffer head use-after-free issue.
This patch (of 2):
Syzbot has reported that after nilfs2 detects filesystem corruption and
falls back to read-only, inconsistencies in the buffer state may occur.
One of the inconsistencies is that when nilfs2 calls mark_buffer_dirty()
to set a data or metadata buffer as dirty, but it detects that the buffer
is not in the uptodate state:
WARNING: CPU: 0 PID: 6049 at fs/buffer.c:1177 mark_buffer_dirty+0x2e5/0x520

The other is when nilfs_btree_propagate(), which propagates the dirty

</TASK>
Both of these issues are caused by the callbacks that handle the
page/folio write requests, forcibly clear various states, including the
working state of the buffers they hold, at unexpected times when they
detect read-only fallback.
Fix these issues by checking if the buffer is referenced before clearing
the page/folio state, and skipping the clear if it is.

------------------
From: Ryusuke Konishi <konishi.ryusuke@gmail.com>
commit 367a9bffabe08c04f6d725032cce3d891b2b9e1a upstream.
nilfs_lookup_dirty_data_buffers(), which iterates through the buffers
attached to dirty data folios/pages, accesses the attached buffers without
locking the folios/pages.
For data cache, nilfs_clear_folio_dirty() may be called asynchronously
when the file system degenerates to read only, so
nilfs_lookup_dirty_data_buffers() still has the potential to cause use
after free issues when buffers lose the protection of their dirty state
midway due to this asynchronous clearing and are unintentionally freed by
try_to_free_buffers().
Eliminate this race issue by adjusting the lock section in this function.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jiaqing Zhao <jiaqing.zhao@linux.intel.com>
commit 16aae4c64600a6319a6f10dbff833fa198bf9599 upstream.
The PCI function 2 on ASIX AX99100 PCIe to Multi I/O Controller can be
configured as a single-port parallel port controller. The subvendor id
is 0x2000 when configured as parallel port. It supports IEEE-1284 EPP /
ECP with its ECR on BAR1.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Woodhouse <dwmw@amazon.co.uk>
commit 70e6b7d9ae3c63df90a7bba7700e8d5c300c3c60 upstream.
Leaving the PIT interrupt running can cause noticeable steal time for
virtual guests. The VMM generally has a timer which toggles the IRQ input
to the PIC and I/O APIC, which takes CPU time away from the guest. Even
on real hardware, running the counter may use power needlessly (albeit
not much).
Make sure it's turned off if it isn't going to be used.

This reverts commit 3d770d44dd5c6316913b003790998404636ec2a8.
The backport for linux-5.4.y, commit 3d770d44dd5c ("btrfs: avoid
monopolizing a core when activating a swap file"), inserted
cond_resched() in the wrong location.
Revert it now; a subsequent commit will re-backport the original patch.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Filipe Manana <fdmanana@suse.com>
commit 2c8507c63f5498d4ee4af404a8e44ceae4345056 upstream.
This commit re-attempts the backport of the change to the linux-5.4.y
branch. Commit 3d770d44dd5c ("btrfs: avoid monopolizing a core when
activating a swap file") on this branch was reverted.
During swap activation we iterate over the extents of a file and we can
have many thousands of them, so we can end up in a busy loop monopolizing
a core. Avoid this by doing a voluntary reschedule after processing each
extent.

...followed by more symptoms of corruption, with similar stacks:
refcount_t: underflow; use-after-free.
kernel BUG at lib/list_debug.c:62!
Kernel panic - not syncing: Oops - BUG: Fatal exception
This happens because pps_device_destruct() frees the pps_device with the
embedded cdev immediately after calling cdev_del(), but, as the comment
above cdev_del() notes, fops for previously opened cdevs are still
callable even after cdev_del() returns. I think this bug has always
been there: I can't explain why it suddenly started happening every time
I reboot this particular board.
In commit d953e0e837e6 ("pps: Fix a use-after free bug when
unregistering a source."), George Spelvin suggested removing the
embedded cdev. That seems like the simplest way to fix this, so I've
implemented his suggestion, using __register_chrdev() with pps_idr
becoming the source of truth for which minor corresponds to which
device.
But now that pps_idr defines userspace visibility instead of cdev_add(),
we need to be sure the pps->dev refcount can't reach zero while
userspace can still find it again. So, the idr_remove() call moves to
pps_unregister_cdev(), and pps_idr now holds a reference to pps->dev.
pps_core: source serial1 got cdev (251:1)
<...>
pps pps1: removed
pps_core: unregistering pps1
pps_core: deallocating pps1

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Stefan Berger <stefanb@linux.ibm.com>
commit be84f32bb2c981ca670922e047cdde1488b233de upstream.
->d_name.name can change on rename and the earlier value can be freed;
there are conditions sufficient to stabilize it (->d_lock on dentry,
->d_lock on its parent, ->i_rwsem exclusive on the parent's inode,
rename_lock), but none of those are met at any of the sites. Take a stable
snapshot of the name instead.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Xin Long <lucien.xin@gmail.com>
commit 37aa50c539bcbcc01767e515bd170787fcfc0f33 upstream.
This patch is to introduce vlan_dev_free_egress_priority() to
free egress priority for vlan dev, and keep vlan_dev_uninit()
static as .ndo_uninit. It makes the code more clear and safer
when adding new code in vlan_dev_uninit() in the future.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Xin Long <lucien.xin@gmail.com>
commit d6ff94afd90b0ce8d1715f8ef77d4347d7a7f2c0 upstream.
Shuang Li reported an QinQ issue by simply doing:
# ip link add dummy0 type dummy
# ip link add link dummy0 name dummy0.1 type vlan id 1
# ip link add link dummy0.1 name dummy0.1.2 type vlan id 2
# rmmod 8021q
unregister_netdevice: waiting for dummy0.1 to become free. Usage count = 1
When rmmods 8021q, all vlan devs are deleted from their real_dev's vlan grp
and added into list_kill by unregister_vlan_dev(). dummy0.1 is unregistered
before dummy0.1.2, as it's using for_each_netdev() in __rtnl_kill_links().
When unregisters dummy0.1, dummy0.1.2 is not unregistered in the event of
NETDEV_UNREGISTER, as it's been deleted from dummy0.1's vlan grp. However,
due to dummy0.1.2 still holding dummy0.1, dummy0.1 will keep waiting in
netdev_wait_allrefs(), while dummy0.1.2 will never get unregistered and
release dummy0.1, as it delays dev_put until calling dev->priv_destructor,
vlan_dev_free().
This issue was introduced by Commit 563bcbae3ba2 ("net: vlan: fix a UAF in
vlan_dev_real_dev()"), and this patch is to fix it by moving dev_put() into
vlan_dev_uninit(), which is called after NETDEV_UNREGISTER event but before
netdev_wait_allrefs().
Fixes: 563bcbae3ba2 ("net: vlan: fix a UAF in vlan_dev_real_dev()")

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Long Li <longli@microsoft.com>
commit 87c4b5e8a6b65189abd9ea5010ab308941f964a4 upstream.
In StorVSC, payload->range.len is used to indicate if this SCSI command
carries payload. This data is allocated as part of the private driver data
by the upper layer and may get passed to lower driver uninitialized.
For example, the SCSI error handling mid layer may send TEST_UNIT_READY or
REQUEST_SENSE while reusing the buffer from a failed command. The private
data section may have stale data from the previous command.
If the SCSI command doesn't carry payload, the driver may use this value as
is for communicating with host, resulting in possible corruption.
Fix this by always initializing this value.
Fixes: be0cf6ca301c ("scsi: storvsc: Set the tablesize based on the information given by the host")

[ Upstream commit a9887010ed2da3fddaff83ceec80e2b71be8a966 ]
According to the BER encoding rules, integer value should be encoded
as two's complement, and if the highest bit of a positive integer
is 1, should add a leading zero-octet.
The kernel's built-in RSA algorithm cannot recognize negative numbers
when parsing keys, so it can pass this test case.
Export the key to file and run the following command to verify the
fix result:

[ Upstream commit 79e6e2f3f3ff345947075341781e900e4f70db81 ]
Changes from v1:
* replace some accidental spaces with tabs
In commit f145d411a67e ("crypto: rsa - implement Chinese Remainder Theorem
for faster private key operations") we have started to use the additional
primes and coefficients for RSA private key operations. However, these
additional parameters are not present (defined as 0 integers) in the RSA
test vectors.
Some parameters were borrowed from OpenSSL, so I was able to find the
source. I could not find the public source for 1 vector though, so had to
recover the parameters by implementing Appendix C from [1].

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ignat Korchagin <ignat@cloudflare.com>
[ Upstream commit 9d2bb9a74b2877f100637d6ab5685bcd33c69d44 ]
Two more fixes:
* some test vectors in commit 79e6e2f3f3ff ("crypto: testmgr - populate
RSA CRT parameters in RSA test vectors") had misplaced commas, which
break the test and trigger KASAN warnings at least on x86-64
* pkcs1pad test vector did not have its CRT parameters
Fixes: 79e6e2f3f3ff ("crypto: testmgr - populate RSA CRT parameters in RSA test vectors")

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Carlos Galo <carlosgalo@google.com>
[ Upstream commit 72ba14deb40a9e9668ec5e66a341ed657e5215c2 ]
The current implementation of the mark_victim tracepoint provides only the
process ID (pid) of the victim process. This limitation poses challenges
for userspace tools requiring real-time OOM analysis and intervention.
Although this information is available from the kernel logs, it’s not
the appropriate format to provide OOM notifications. In Android, BPF
programs are used with the mark_victim trace events to notify userspace of
an OOM kill. For consistency, update the trace event to include the same
information about the OOMed victim as the kernel logs.
- UID
In Android each installed application has a unique UID. Including
the `uid` assists in correlating OOM events with specific apps.
- Process Name (comm)
Enables identification of the affected process.
- OOM Score
Will allow userspace to get additional insight of the relative kill
priority of the OOM victim. In Android, the oom_score_adj is used to
categorize app state (foreground, background, etc.), which aids in
analyzing user-perceptible impacts of OOM events [1].
- Total VM, RSS Stats, and pgtables
Amount of memory used by the victim that will, potentially, be freed up
by killing it.

This is because thousands of processes are in the OOM cgroup, it takes a
long time to traverse all of them. As a result, this lead to soft lockup
in the OOM process.
To fix this issue, call 'cond_resched' in the 'mem_cgroup_scan_tasks'
function per 1000 iterations. For global OOM, call
'touch_softlockup_watchdog' per 1000 iterations to avoid this issue.

From: Wesley Cheng <quic_wcheng@quicinc.com>
[ Upstream commit 461ee467507cb98a348fa91ff8460908bb0ea423 ]
Since EP0 transactions need to be completed before the controller halt
sequence is finished, this may take some time depending on the host and the
enabled functions. Increase the controller halt timeout, so that we give
the controller sufficient time to handle EP0 transfers.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Selvarasu Ganesan <selvarasu.g@samsung.com>
[ Upstream commit d3a8c28426fc1fb3252753a9f1db0d691ffc21b0 ]
There is a frequent timeout during controller enter/exit from halt state
after toggling the run_stop bit by SW. This timeout occurs when
performing frequent role switches between host and device, causing
device enumeration issues due to the timeout. This issue was not present
when USB2 suspend PHY was disabled by passing the SNPS quirks
(snps,dis_u2_susphy_quirk and snps,dis_enblslpm_quirk) from the DTS.
However, there is a requirement to enable USB2 suspend PHY by setting of
GUSB2PHYCFG.ENBLSLPM and GUSB2PHYCFG.SUSPHY bits when controller starts
in gadget or host mode results in the timeout issue.
This commit addresses this timeout issue by ensuring that the bits
GUSB2PHYCFG.ENBLSLPM and GUSB2PHYCFG.SUSPHY are cleared before starting
the dwc3_gadget_run_stop sequence and restoring them after the
dwc3_gadget_run_stop sequence is completed.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Davidlohr Bueso <dave@stgolabs.net>
[ Upstream commit 8653d71ce3763aedcf3d2331f59beda3fecd79e4 ]
Currently a tasklet is used to transmit input substream buffer
data. However, tasklets have long been deprecated as being too
heavy on the system by running in irq context - and this is not
a performance critical path. If a higher priority process wants
to run, it must wait for the tasklet to finish before doing so.
Deferring work to a workqueue and executing in process context
should be fine considering the callback already does
f_midi_do_transmit() under the transmit_lock and thus changes in
semantics are ok regarding concurrency - tasklets being serialized
against itself.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jill Donahue <jilliandonahue58@gmail.com>
[ Upstream commit 4ab37fcb42832cdd3e9d5e50653285ca84d6686f ]
When using USB MIDI, a lock is attempted to be acquired twice through a
re-entrant call to f_midi_transmit, causing a deadlock.
Fix it by using queue_work() to schedule the inner f_midi_transmit() via
a high priority work queue from the completion handler.

==================================================================
f8 corresponds to KASAN_VMALLOC_INVALID which means the area is not
initialised hence not supposed to be used yet.
Powerpc text patching infrastructure allocates a virtual memory area
using get_vm_area() and flags it as VM_ALLOC. But that flag is meant
to be used for vmalloc() and vmalloc() allocated memory is not
supposed to be used before a call to __vmalloc_node_range() which is
never called for that area.
That went undetected until commit e4137f08816b ("mm, kasan, kmsan:
instrument copy_from/to_kernel_nofault")
The area allocated by text_area_cpu_up() is not vmalloc memory, it is
mapped directly on demand when needed by map_kernel_page(). There is
no VM flag corresponding to such usage, so just pass no flag. That way
the area will be unpoisonned and usable immediately.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kuniyuki Iwashima <kuniyu@amazon.com>
[ Upstream commit 9593172d93b9f91c362baec4643003dc29802929 ]
syzkaller reported a use-after-free in geneve_find_dev() [0]
without repro.
geneve_configure() links struct geneve_dev.next to
net_generic(net, geneve_net_id)->geneve_list.
The net here could differ from dev_net(dev) if IFLA_NET_NS_PID,
IFLA_NET_NS_FD, or IFLA_TARGET_NETNSID is set.
When dev_net(dev) is dismantled, geneve_exit_batch_rtnl() finally
calls unregister_netdevice_queue() for each dev in the netns,
and later the dev is freed.
However, its geneve_dev.next is still linked to the backend UDP
socket netns.
Then, use-after-free will occur when another geneve dev is created
in the netns.
Let's call geneve_dellink() instead in geneve_destroy_tunnels().

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kuniyuki Iwashima <kuniyu@amazon.com>
[ Upstream commit 4ccacf86491d33d2486b62d4d44864d7101b299d ]
Brad Spengler reported the list_del() corruption splat in
gtp_net_exit_batch_rtnl(). [0]
Commit eb28fd76c0a0 ("gtp: Destroy device along with udp socket's netns
dismantle.") added the for_each_netdev() loop in gtp_net_exit_batch_rtnl()
to destroy devices in each netns as done in geneve and ip tunnels.
However, this could trigger ->dellink() twice for the same device during
->exit_batch_rtnl().
Say we have two netns A & B and gtp device B that resides in netns B but
whose UDP socket is in netns A.
1. cleanup_net() processes netns A and then B.
2. gtp_net_exit_batch_rtnl() finds the device B while iterating
netns A's gn->gtp_dev_list and calls ->dellink().
[ device B is not yet unlinked from netns B
as unregister_netdevice_many() has not been called. ]
3. gtp_net_exit_batch_rtnl() finds the device B while iterating
netns B's for_each_netdev() and calls ->dellink().
gtp_dellink() cleans up the device's hash table, unlinks the dev from
gn->gtp_dev_list, and calls unregister_netdevice_queue().
Basically, calling gtp_dellink() multiple times is fine unless
CONFIG_DEBUG_LIST is enabled.
Let's remove for_each_netdev() in gtp_net_exit_batch_rtnl() and
delegate the destruction to default_device_exit_batch() as done
in bareudp.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kuniyuki Iwashima <kuniyu@amazon.com>
[ Upstream commit 62fab6eef61f245dc8797e3a6a5b890ef40e8628 ]
As explained in the previous patch, iterating for_each_netdev() and
gn->geneve_list during ->exit_batch_rtnl() could trigger ->dellink()
twice for the same device.
If CONFIG_DEBUG_LIST is enabled, we will see a list_del() corruption
splat in the 2nd call of geneve_dellink().
Let's remove for_each_netdev() in geneve_destroy_tunnels() and delegate
that part to default_device_exit_batch().

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Cong Wang <xiyou.wangcong@gmail.com>
[ Upstream commit 3e5796862c692ea608d96f0a1437f9290f44953a ]
This patch fixes a bug in TC flower filter where rules combining a
specific destination port with a source port range weren't working
correctly.
The specific case was when users tried to configure rules like:
tc filter add dev ens38 ingress protocol ip flower ip_proto udp \
dst_port 5000 src_port 2000-3000 action drop
The root cause was in the flow dissector code. While both
FLOW_DISSECTOR_KEY_PORTS and FLOW_DISSECTOR_KEY_PORTS_RANGE flags
were being set correctly in the classifier, the __skb_flow_dissect_ports()
function was only populating one of them: whichever came first in
the enum check. This meant that when the code needed both a specific
port and a port range, one of them would be left as 0, causing the
filter to not match packets as expected.
Fix it by removing the either/or logic and instead checking and
populating both key types independently when they're in use.

------------------
From: Cong Wang <xiyou.wangcong@gmail.com>
[ Upstream commit 69ab34f705fbfabcace64b5d53bb7a4450fac875 ]
Fix how port range keys are handled in __skb_flow_bpf_to_target() by:
- Separating PORTS and PORTS_RANGE key handling
- Using correct key_ports_range structure for range keys
- Properly initializing both key types independently
This ensures port range information is correctly stored in its dedicated
structure rather than incorrectly using the regular ports key structure.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andrey Vatoropin <a.vatoropin@crpt.ru>
[ Upstream commit 3fb3cb4350befc4f901c54e0cb4a2a47b1302e08 ]
Size of variable sd_gain equals four bytes - DA9150_QIF_SD_GAIN_SIZE.
Size of variable shunt_val equals two bytes - DA9150_QIF_SHUNT_VAL_SIZE.
The expression sd_gain * shunt_val is currently being evaluated using
32-bit arithmetic. So during the multiplication an overflow may occur.
As the value of type 'u64' is used as storage for the eventual result, put
ULL variable at the first position of each expression in order to give the
compiler complete information about the proper arithmetic to use. According
to C99 the guaranteed width for a variable of type 'unsigned long long' >=
64 bits.
Remove the explicit cast to u64 as it is meaningless.
Just for the sake of consistency, perform the similar trick with another
expression concerning 'iavg'.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sumit Garg <sumit.garg@linaro.org>
commit 70b0d6b0a199c5a3ee6c72f5e61681ed6f759612 upstream.
OP-TEE supplicant is a user-space daemon and it's possible for it
be hung or crashed or killed in the middle of processing an OP-TEE
RPC call. It becomes more complicated when there is incorrect shutdown
ordering of the supplicant process vs the OP-TEE client application which
can eventually lead to system hang-up waiting for the closure of the
client application.
Allow the client process waiting in kernel for supplicant response to
be killed rather than indefinitely waiting in an unkillable state. Also,
a normal uninterruptible wait should not have resulted in the hung-task
watchdog getting triggered, but the endless loop would.
This fixes issues observed during system reboot/shutdown when supplicant
got hung for some reason or gets crashed/killed which lead to client
getting hung in an unkillable state. It in turn lead to system being in
hung up state requiring hard power off/on to recover.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sven Eckelmann <sven@narfation.org>
commit 8c8ecc98f5c65947b0070a24bac11e12e47cc65d upstream.
The ELP worker needs to calculate new metric values for all neighbors
"reachable" over an interface. Some of the used metric sources require
locks which might need to sleep. This sleep is incompatible with the RCU
list iterator used for the recorded neighbors. The initial approach to work
around of this problem was to queue another work item per neighbor and then
run this in a new context.
Even when this solved the RCU vs might_sleep() conflict, it has a major
problems: Nothing was stopping the work item in case it is not needed
anymore - for example because one of the related interfaces was removed or
the batman-adv module was unloaded - resulting in potential invalid memory
accesses.
Directly canceling the metric worker also has various problems:
* cancel_work_sync for a to-be-deactivated interface is called with
rtnl_lock held. But the code in the ELP metric worker also tries to use
rtnl_lock() - which will never return in this case. This also means that
cancel_work_sync would never return because it is waiting for the worker
to finish.
* iterating over the neighbor list for the to-be-deactivated interface is
currently done using the RCU specific methods. Which means that it is
possible to miss items when iterating over it without the associated
spinlock - a behaviour which is acceptable for a periodic metric check
but not for a cleanup routine (which must "stop" all still running
workers)
The better approch is to get rid of the per interface neighbor metric
worker and handle everything in the interface worker. The original problems
are solved by:
* creating a list of neighbors which require new metric information inside
the RCU protected context, gathering the metric according to the new list
outside the RCU protected context
* only use rcu_trylock inside metric gathering code to avoid a deadlock
when the cancel_delayed_work_sync is called in the interface removal code
(which is called with the rtnl_lock held)

------------------
From: Arnd Bergmann <arnd@arndb.de>
[ Upstream commit 1f7a4f98c11fbeb18ed21f3b3a497e90a50ad2e0 ]
There is a warning about unused variables when building with W=1 and no procfs:
net/sunrpc/cache.c:1660:30: error: 'cache_flush_proc_ops' defined but not used [-Werror=unused-const-variable=]
1660 | static const struct proc_ops cache_flush_proc_ops = {

1598 | static const struct proc_ops cache_channel_proc_ops = {
| ^~~~~~~~~~~~~~~~~~~~~~
These are used inside of an #ifdef, so replacing that with an
IS_ENABLED() check lets the compiler see how they are used while
still dropping them during dead code elimination.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ido Schimmel <idosch@nvidia.com>
[ Upstream commit 0e4427f8f587c4b603475468bb3aee9418574893 ]
After commit 22600596b675 ("ipv4: give an IPv4 dev to blackhole_netdev")
IPv4 neighbors can be constructed on the blackhole net device, but they
are constructed with an output function (neigh_direct_output()) that
simply calls dev_queue_xmit(). The latter will transmit packets via
'skb->dev' which might not be the blackhole net device if dst_dev_put()
switched 'dst->dev' to the blackhole net device while another CPU was
using the dst entry in ip_output(), but after it already initialized
'skb->dev' from 'dst->dev'.
Specifically, the following can happen:
CPU1 CPU2
udp_sendmsg(sk1) udp_sendmsg(sk2)
udp_send_skb() [...]
ip_output()
skb->dev = skb_dst(skb)->dev
dst_dev_put()
dst->dev = blackhole_netdev
ip_finish_output2()
resolves neigh on dst->dev
neigh_output()
neigh_direct_output()
dev_queue_xmit()
This will result in IPv4 packets being sent without an Ethernet header
via a valid net device:
tcpdump: verbose output suppressed, use -v[v]... for full protocol decode
listening on enp9s0, link-type EN10MB (Ethernet), snapshot length 262144 bytes
22:07:02.329668 20:00:40:11:18:fb > 45:00:00:44:f4:94, ethertype Unknown
(0x58c6), length 68:
0x0000: 8dda 74ca f1ae ca6c ca6c 0098 969c 0400 ..t....l.l......
0x0010: 0000 4730 3f18 6800 0000 0000 0000 9971 ..G0?.h........q

0x0030: 8add ab96 e052 .....R
Fix by making sure that neighbors are constructed on top of the
blackhole net device with an output function that simply consumes the
packets, in a similar fashion to dst_discard_out() and
blackhole_netdev_xmit().

From: Sean Anderson <sean.anderson@linux.dev>
[ Upstream commit fa52f15c745ce55261b92873676f64f7348cfe82 ]
Stats calculations involve a RMW to add the stat update to the existing
value. This is currently not protected by any synchronization mechanism,
so data races are possible. Add a spinlock to protect the update. The
reader side could be protected using u64_stats, but we would still need
a spinlock for the update side anyway. And we always do an update
immediately before reading the stats anyway.

directly. To the best of what I could find, this is not true, and
creates problems.
Without DACCONTROL17 bit index 7 set for the left channel, as well as
DACCONTROL20 bit index 7 set for the right channel, I cannot get any
analog audio out on Left Out 2 and Right Out 2 respectively, despite the
DAPM routes claiming that this should be possible. Furthermore, the same
is the case for Left Out 1 and Right Out 1, showing that those two don't
have a direct route from DAC to output bypassing the mixer either.
Those control bits toggle whether the DACs are fed (stale bread?) into
their respective mixers. If one "unmutes" the mixer controls in
alsamixer, then sure, the audio output works, but if it doesn't work
without the mixer being fed the DAC input then evidently it's not a
direct output from the DAC.
ES8328/ES8388 are seemingly not alone in this. ES8323, which uses a
separate driver for what appears to be a very similar register map,
simply flips those two bits on in its probe function, and then pretends
there is no power management whatsoever for the individual controls.
Fair enough.
My theory as to why nobody has noticed this up to this point is that
everyone just assumes it's their fault when they had to unmute an
additional control in ALSA.
Fix this in the es8328 driver by removing the erroneous direct route,
then get rid of the playback switch controls and have those bits tied to
the mixer's widget instead, which until now had no register to play
with.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Philo Lu <lulie@linux.alibaba.com>
[ Upstream commit de2c211868b9424f9aa9b3432c4430825bafb41b ]
We found an issue when using bpf_redirect with ipvs NAT mode after
commit ff70202b2d1a ("dev_forward_skb: do not scrub skb mark within
the same name space"). Particularly, we use bpf_redirect to return
the skb directly back to the netif it comes from, i.e., xnet is
false in skb_scrub_packet(), and then ipvs_property is preserved
and SNAT is skipped in the rx path.
ipvs_property has been already cleared when netns is changed in
commit 2b5ec1a5f973 ("netfilter/ipvs: clear ipvs_property flag when
SKB net namespace changed"). This patch just clears it in spite of
netns.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Russell Senior <russell@personaltelco.net>
[ Upstream commit bebe35bb738b573c32a5033499cd59f20293f2a3 ]
I still have some Soekris net4826 in a Community Wireless Network I
volunteer with. These devices use an AMD SC1100 SoC. I am running
OpenWrt on them, which uses a patched kernel, that naturally has
evolved over time. I haven't updated the ones in the field in a
number of years (circa 2017), but have one in a test bed, where I have
intermittently tried out test builds.
A few years ago, I noticed some trouble, particularly when "warm
booting", that is, doing a reboot without removing power, and noticed
the device was hanging after the kernel message:
[ 0.081615] Working around Cyrix MediaGX virtual DMA bugs.
If I removed power and then restarted, it would boot fine, continuing
through the message above, thusly:
[ 0.081615] Working around Cyrix MediaGX virtual DMA bugs.
[ 0.090076] Enable Memory-Write-back mode on Cyrix/NSC processor.
[ 0.100000] Enable Memory access reorder on Cyrix/NSC processor.
[ 0.100070] Last level iTLB entries: 4KB 0, 2MB 0, 4MB 0
[ 0.110058] Last level dTLB entries: 4KB 0, 2MB 0, 4MB 0, 1GB 0
[ 0.120037] CPU: NSC Geode(TM) Integrated Processor by National Semi (family: 0x5, model: 0x9, stepping: 0x1)
[...]
In order to continue using modern tools, like ssh, to interact with
the software on these old devices, I need modern builds of the OpenWrt
firmware on the devices. I confirmed that the warm boot hang was still
an issue in modern OpenWrt builds (currently using a patched linux
v6.6.65).
Last night, I decided it was time to get to the bottom of the warm
boot hang, and began bisecting. From preserved builds, I narrowed down
the bisection window from late February to late May 2019. During this
period, the OpenWrt builds were using 4.14.x. I was able to build
using period-correct Ubuntu 18.04.6. After a number of bisection
iterations, I identified a kernel bump from 4.14.112 to 4.14.113 as
the commit that introduced the warm boot hang.
https://github.com/openwrt/openwrt/commit/07aaa7e3d62ad32767d7067107db64b6ade81537
Looking at the upstream changes in the stable kernel between 4.14.112
and 4.14.113 (tig v4.14.112..v4.14.113), I spotted a likely suspect:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=20afb90f730982882e65b01fb8bdfe83914339c5
So, I tried reverting just that kernel change on top of the breaking
OpenWrt commit, and my warm boot hang went away.
Presumably, the warm boot hang is due to some register not getting
cleared in the same way that a loss of power does. That is
approximately as much as I understand about the problem.
More poking/prodding and coaching from Jonas Gorski, it looks
like this test patch fixes the problem on my board: Tested against
v6.6.67 and v4.14.113.

commit 0d39844150546fa1415127c5fbae26db64070dd3 upstream.
A low attr::freq value cannot be set via IOC_PERIOD on some platforms.
The perf_event_check_period() introduced in:
81ec3f3c4c4d ("perf/x86: Add check_period PMU callback")
was intended to check the period, rather than the frequency.
A low frequency may be mistakenly rejected by limit_period().
Fix it.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nikita Zhandarovich <n.zhandarovich@fintech.ru>
commit 1cf9631d836b289bd5490776551961c883ae8a4f upstream.
Syzbot reports [1] a warning in usb_submit_urb() triggered by
inconsistencies between expected and actually present endpoints
in gl620a driver. Since genelink_bind() does not properly
verify whether specified eps are in fact provided by the device,
in this case, an artificially manufactured one, one may get a
mismatch.
Fix the issue by resorting to a usbnet utility function
usbnet_get_endpoints(), usually reserved for this very problem.
Check for endpoints and return early before proceeding further if
any are missing.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: BH Hsieh <bhsieh@nvidia.com>
commit 55f1a5f7c97c3c92ba469e16991a09274410ceb7 upstream.
Observed VBUS_OVERRIDE & ID_OVERRIDE might be programmed
with unexpected value prior to XUSB PADCTL driver, this
could also occur in virtualization scenario.
For example, UEFI firmware programs ID_OVERRIDE=GROUNDED to set
a type-c port to host mode and keeps the value to kernel.
If the type-c port is connected a usb host, below errors can be
observed right after usb host mode driver gets probed. The errors
would keep until usb role class driver detects the type-c port
as device mode and notifies usb device mode driver to set both
ID_OVERRIDE and VBUS_OVERRIDE to correct value by XUSB PADCTL
driver.
[ 173.765814] usb usb3-port2: Cannot enable. Maybe the USB cable is bad?
[ 173.765837] usb usb3-port2: config error
Taking virtualization into account, asserting XUSB PADCTL
reset would break XUSB functions used by other guest OS,
hence only reset VBUS & ID OVERRIDE of the port in
utmi_phy_init.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Gleixner <tglx@linutronix.de>
commit 82c387ef7568c0d96a918a5a78d9cad6256cfa15 upstream.
David reported a warning observed while loop testing kexec jump:
Interrupts enabled after irqrouter_resume+0x0/0x50
WARNING: CPU: 0 PID: 560 at drivers/base/syscore.c:103 syscore_resume+0x18a/0x220
kernel_kexec+0xf6/0x180
__do_sys_reboot+0x206/0x250
do_syscall_64+0x95/0x180
The corresponding interrupt flag trace:
hardirqs last enabled at (15573): [<ffffffffa8281b8e>] __up_console_sem+0x7e/0x90
hardirqs last disabled at (15580): [<ffffffffa8281b73>] __up_console_sem+0x63/0x90
That means __up_console_sem() was invoked with interrupts enabled. Further
instrumentation revealed that in the interrupt disabled section of kexec
jump one of the syscore_suspend() callbacks woke up a task, which set the
NEED_RESCHED flag. A later callback in the resume path invoked
cond_resched() which in turn led to the invocation of the scheduler:
__cond_resched+0x21/0x60
down_timeout+0x18/0x60
acpi_os_wait_semaphore+0x4c/0x80
acpi_ut_acquire_mutex+0x3d/0x100

kernel_kexec+0x145/0x1c0
__do_sys_reboot+0xeb/0x240
do_syscall_64+0x95/0x180
This is a long standing problem, which probably got more visible with
the recent printk changes. Something does a task wakeup and the
scheduler sets the NEED_RESCHED flag. cond_resched() sees it set and
invokes schedule() from a completely bogus context. The scheduler
enables interrupts after context switching, which causes the above
warning at the end.
Quite some of the code paths in syscore_suspend()/resume() can result in
triggering a wakeup with the exactly same consequences. They might not
have done so yet, but as they share a lot of code with normal operations
it's just a question of time.
The problem only affects the PREEMPT_NONE and PREEMPT_VOLUNTARY scheduling
models. Full preemption is not affected as cond_resched() is disabled and
the preemption check preemptible() takes the interrupt disabled flag into
account.
Cure the problem by adding a corresponding check into cond_resched().

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Quang Le <quanglex97@gmail.com>
commit 647cef20e649c576dff271e018d5d15d998b629d upstream.
Expected behaviour:
In case we reach scheduler's limit, pfifo_tail_enqueue() will drop a
packet in scheduler's queue and decrease scheduler's qlen by one.
Then, pfifo_tail_enqueue() enqueue new packet and increase
scheduler's qlen by one. Finally, pfifo_tail_enqueue() return
`NET_XMIT_CN` status code.
Weird behaviour:
In case we set `sch->limit == 0` and trigger pfifo_tail_enqueue() on a
scheduler that has no packet, the 'drop a packet' step will do nothing.
This means the scheduler's qlen still has value equal 0.
Then, we continue to enqueue new packet and increase scheduler's qlen by
one. In summary, we can leverage pfifo_tail_enqueue() to increase qlen by
one and return `NET_XMIT_CN` status code.
The problem is:
Let's say we have two qdiscs: Qdisc_A and Qdisc_B.
- Qdisc_A's type must have '->graft()' function to create parent/child relationship.
Let's say Qdisc_A's type is `hfsc`. Enqueue packet to this qdisc will trigger `hfsc_enqueue`.
- Qdisc_B's type is pfifo_head_drop. Enqueue packet to this qdisc will trigger `pfifo_tail_enqueue`.
- Qdisc_B is configured to have `sch->limit == 0`.
- Qdisc_A is configured to route the enqueued's packet to Qdisc_B.
Enqueue packet through Qdisc_A will lead to:
- hfsc_enqueue(Qdisc_A) -> pfifo_tail_enqueue(Qdisc_B)
- Qdisc_B->q.qlen += 1
- pfifo_tail_enqueue() return `NET_XMIT_CN`
- hfsc_enqueue() check for `NET_XMIT_SUCCESS` and see `NET_XMIT_CN` => hfsc_enqueue() don't increase qlen of Qdisc_A.
The whole process lead to a situation where Qdisc_A->q.qlen == 0 and Qdisc_B->q.qlen == 1.
Replace 'hfsc' with other type (for example: 'drr') still lead to the same problem.
This violate the design where parent's qlen should equal to the sum of its childrens'qlen.
Bug impact: This issue can be used for user->kernel privilege escalation when it is reachable.

If drop_monitor is built as a kernel module, syzkaller may have time
to send a netlink NET_DM_CMD_START message during the module loading.
This will call the net_dm_monitor_start() function that uses
a spinlock that has not yet been initialized.
To fix this, let's place resource initialization above the registration
of a generic netlink family.
Found by InfoTeCS on behalf of Linux Verification Center
(linuxtesting.org) with Syzkaller.
Fixes: 9a8afc8d3962 ("Network Drop Monitor: Adding drop monitor implementation & Netlink protocol")

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christian Brauner <brauner@kernel.org>
[ Upstream commit 56d5f3eba3f5de0efdd556de4ef381e109b973a9 ]
In [1] it was reported that the acct(2) system call can be used to
trigger NULL deref in cases where it is set to write to a file that
triggers an internal lookup. This can e.g., happen when pointing acc(2)
to /sys/power/resume. At the point the where the write to this file
happens the calling task has already exited and called exit_fs(). A
lookup will thus trigger a NULL-deref when accessing current->fs.
Reorganize the code so that the the final write happens from the
workqueue but with the caller's credentials. This preserves the
(strange) permission model and has almost no regression risk.
This api should stop to exist though.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ma Jun <Jun.Ma2@amd.com>
[ Upstream commit e372baeb3d336b20fd9463784c577fd8824497cd ]
Some customer platforms do not enable mmconfig for various reasons,
such as bios bug, and therefore cannot access the GPU extend configuration
space through mmio.
When the system enters the d3cold state and resumes, the amdgpu driver
fails to resume because the extend configuration space registers of
GPU can't be restored. At this point, Usually we only see some failure
dmesg log printed by amdgpu driver, it is difficult to find the root
cause.
Therefor print a warnning message if the system can't access the
extended configuration space register when using large bar.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Deucher <alexander.deucher@amd.com>
[ Upstream commit 099bffc7cadff40bfab1517c3461c53a7a38a0d7 ]
There was a quirk added to add a workaround for a Sapphire
RX 5600 XT Pulse that didn't allow BAR resizing. However,
the quirk caused a regression with runtime pm on Dell laptops
using those chips, rather than narrowing the scope of the
resizing quirk, add a quirk to prevent amdgpu from resizing
the BAR on those Dell platforms unless runtime pm is disabled.
v2: update commit message, add runpm check
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/1707

From: Rob Herring (Arm) <robh@kernel.org>
commit 75f1f311d883dfaffb98be3c1da208d6ed5d4df9 upstream.
This reverts commit 267b21d0bef8e67dbe6c591c9991444e58237ec9.
Turns out some DTs do depend on this behavior. Specifically, a
downstream Pixel 6 DT. Revert the change at least until we can decide if
the DT spec can be changed instead.

This happens due to the malformed report items sent by the emulated device
which results in a report, that has no fields, being added to the report list.
Due to this appleir_input_configured() is never called, hidinput_connect()
fails which results in the HID_CLAIMED_INPUT flag is not being set. However,
it does not make appleir_probe() fail and lets the event callback to be
called without the associated input device.
Thus, add a check for the HID_CLAIMED_INPUT flag and leave the event hook
early if the driver didn't claim any input_dev for some reason. Moreover,
some other hid drivers accessing input_dev in their event callbacks do have
similar checks, too.
Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hoku Ishibe <me@hokuishi.be>
commit 1ee5aa765c22a0577ec552d460bf2035300b4b51 upstream.
Dell XPS 13 7390 with the Realtek ALC3271 codec experiences
persistent humming noise when the power_save mode is enabled.
This issue occurs when the codec enters power saving mode,
leading to unwanted noise from the speakers.
This patch adds the affected model (PCI ID 0x1028:0x0962) to the
power_save denylist to ensure power_save is disabled by default,
preventing power-off related noise issues.
Steps to Reproduce
1. Boot the system with `snd_hda_intel` loaded.
2. Verify that `power_save` mode is enabled:
```sh
cat /sys/module/snd_hda_intel/parameters/power_save
````
output: 10 (default power save timeout)
3. Wait for the power save timeout
4. Observe a persistent humming noise from the speakers
5. Disable `power_save` manually:
```sh
echo 0 | sudo tee /sys/module/snd_hda_intel/parameters/power_save
````
6. Confirm that the noise disappears immediately.
This issue has been observed on my system, and this patch
successfully eliminates the unwanted noise. If other users
experience similar issues, additional reports would be helpful.

From: Ahmed S. Darwish <darwi@linutronix.de>
commit 8177c6bedb7013cf736137da586cf783922309dd upstream.
CPUID leaf 0x2 emits one-byte descriptors in its four output registers
EAX, EBX, ECX, and EDX. For these descriptors to be valid, the most
significant bit (MSB) of each register must be clear.
The historical Git commit:
019361a20f016 ("- pre6: Intel: start to add Pentium IV specific stuff (128-byte cacheline etc)...")
introduced leaf 0x2 output parsing. It only validated the MSBs of EAX,
EBX, and ECX, but left EDX unchecked.
Validate EDX's most-significant bit.

------------------
From: Ahmed S. Darwish <darwi@linutronix.de>
commit f6bdaab79ee4228a143ee1b4cb80416d6ffc0c63 upstream.
CPUID leaf 0x2's one-byte TLB descriptors report the number of entries
for specific TLB types, among other properties.
Typically, each emitted descriptor implies the same number of entries
for its respective TLB type(s). An emitted 0x63 descriptor is an
exception: it implies 4 data TLB entries for 1GB pages and 32 data TLB
entries for 2MB or 4MB pages.
For the TLB descriptors parsing code, the entry count for 1GB pages is
encoded at the intel_tlb_table[] mapping, but the 2MB/4MB entry count is
totally ignored.
Update leaf 0x2's parsing logic 0x2 to account for 32 data TLB entries
for 2MB/4MB pages implied by the 0x63 descriptor.

From: Nikita Zhandarovich <n.zhandarovich@fintech.ru>
commit 59b348be7597c4a9903cb003c69e37df20c04a30 upstream.
Syzbot keeps reporting an issue [1] that occurs when erroneous symbols
sent from userspace get through into user_alpha2[] via
regulatory_hint_user() call. Such invalid regulatory hints should be
rejected.
While a sanity check from commit 47caf685a685 ("cfg80211: regulatory:
reject invalid hints") looks to be enough to deter these very cases,
there is a way to get around it due to 2 reasons.
1) The way isalpha() works, symbols other than latin lower and
upper letters may be used to determine a country/domain.
For instance, greek letters will also be considered upper/lower
letters and for such characters isalpha() will return true as well.
However, ISO-3166-1 alpha2 codes should only hold latin
characters.
2) While processing a user regulatory request, between
reg_process_hint_user() and regulatory_hint_user() there happens to
be a call to queue_regulatory_request() which modifies letters in
request->alpha2[] with toupper(). This works fine for latin symbols,
less so for weird letter characters from the second part of _ctype[].
Syzbot triggers a warning in is_user_regdom_saved() by first sending
over an unexpected non-latin letter that gets malformed by toupper()
into a character that ends up failing isalpha() check.
Prevent this by enhancing is_an_alpha2() to ensure that incoming
symbols are latin letters and nothing else.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vitaliy Shevtsov <v.shevtsov@mt-integration.ru>
commit 49f27f29446a5bfe633dd2cc0cfebd48a1a5e77f upstream.
It is possible to set both MONITOR_FLAG_COOK_FRAMES and MONITOR_FLAG_ACTIVE
flags simultaneously on the same monitor interface from the userspace. This
causes a sub-interface to be created with no IEEE80211_SDATA_IN_DRIVER bit
set because the monitor interface is in the cooked state and it takes
precedence over all other states. When the interface is then being deleted
the kernel calls WARN_ONCE() from check_sdata_in_driver() because of missing
that bit.
Fix this by rejecting MONITOR_FLAG_COOK_FRAMES if it is set along with
other flags.
Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

commit b2ef51c74b0171fde7eb69b6152d3d2f743ef269 upstream.
rio_add_net() calls device_register() and fails when device_register()
fails. Thus, put_device() should be used rather than kfree(). Add
"mport->net = NULL;" to avoid a use after free issue.

[ Upstream commit e0dc2c1bef722cbf16ae557690861e5f91208129 ]
There's no guarantee here that the file is always with a
NUL-termination, so reading the string may read beyond the
end of the TLV. If that's the last TLV in the file, it can
perhaps even read beyond the end of the file buffer.
Fix that by limiting the print format to the size of the
buffer we have.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Zhang Lixu <lixu.zhang@intel.com>
[ Upstream commit 07583a0010696a17fb0942e0b499a62785c5fc9f ]
The system can experience a random crash a few minutes after the driver is
removed. This issue occurs due to improper handling of memory freeing in
the ishtp_hid_remove() function.
The function currently frees the `driver_data` directly within the loop
that destroys the HID devices, which can lead to accessing freed memory.
Specifically, `hid_destroy_device()` uses `driver_data` when it calls
`hid_ishtp_set_feature()` to power off the sensor, so freeing
`driver_data` beforehand can result in accessing invalid memory.
This patch resolves the issue by storing the `driver_data` in a temporary
variable before calling `hid_destroy_device()`, and then freeing the
`driver_data` after the device is destroyed.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Antoine Tenart <atenart@kernel.org>
[ Upstream commit ee01b2f2d7d0010787c2343463965bbc283a497f ]
In __udp_gso_segment the skb destructor is removed before segmenting the
skb but the socket reference is kept as-is. This is an issue if the
original skb is later orphaned as we can hit the following bug:
kernel BUG at ./include/linux/skbuff.h:3312! (skb_orphan)
RIP: 0010:ip_rcv_core+0x8b2/0xca0
Call Trace:
ip_rcv+0xab/0x6e0
__netif_receive_skb_one_core+0x168/0x1b0
process_backlog+0x384/0x1100
__napi_poll.constprop.0+0xa1/0x370
net_rx_action+0x925/0xe50
The above can happen following a sequence of events when using
OpenVSwitch, when an OVS_ACTION_ATTR_USERSPACE action precedes an
OVS_ACTION_ATTR_OUTPUT action:
1. OVS_ACTION_ATTR_USERSPACE is handled (in do_execute_actions): the skb
goes through queue_gso_packets and then __udp_gso_segment, where its
destructor is removed.
2. The segments' data are copied and sent to userspace.
3. OVS_ACTION_ATTR_OUTPUT is handled (in do_execute_actions) and the
same original skb is sent to its path.
4. If it later hits skb_orphan, we hit the bug.
Fix this by also removing the reference to the socket in
__udp_gso_segment.

[ Upstream commit a466fd7e9fafd975949e5945e2f70c33a94b1a70 ]
del_vqs() frees virtqueues, therefore cfv->vq_tx pointer should be checked
for NULL before calling it, not cfv->vdev. Also the current implementation
is redundant because the pointer cfv->vdev is dereferenced before it is
checked for NULL.
Fix this by checking cfv->vq_tx for NULL instead of cfv->vdev before
calling del_vqs().

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Titus Rwantare <titusr@google.com>
[ Upstream commit 6b6e2e8fd0de3fa7c6f4f8fe6841b01770b2e7bc ]
The `pmbus_identify()` function fails to correctly determine the number
of supported pages on PMBus devices. This occurs because `info->pages`
is implicitly zero-initialised, and `pmbus_set_page()` does not perform
writes to the page register if `info->pages` is not yet initialised.
Without this patch, `info->pages` is always set to the maximum after
scanning.
This patch initialises `info->pages` to `PMBUS_PAGES` before the probing
loop, enabling `pmbus_set_page()` writes to make it out onto the bus
correctly identifying the number of pages. `PMBUS_PAGES` seemed like a
reasonable non-zero number because that's the current result of the
identification process.
Testing was done with a PMBus device in QEMU.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Dumazet <edumazet@google.com>
[ Upstream commit 64e6a754d33d31aa844b3ee66fb93ac84ca1565e ]
syzbot is able to crash hosts [1], using llc and devices
not supporting IFF_TX_SKB_SHARING.
In this case, e1000 driver calls eth_skb_pad(), while
the skb is shared.
Simply replace skb_get() by skb_clone() in net/llc/llc_s_ac.c
Note that e1000 driver might have an issue with pktgen,
because it does not clear IFF_TX_SKB_SHARING, this is an
orthogonal change.
We need to audit other skb_get() uses in net/llc.

From: Nikolay Aleksandrov <razor@blackwall.org>
[ Upstream commit 1a82d19ca2d6835904ee71e2d40fd331098f94a0 ]
Partially revert commit b71724147e73 ("be2net: replace polling with
sleeping in the FW completion path") w.r.t mcc mutex it introduces and the
use of usleep_range. The be2net be_ndo_bridge_getlink() callback is
called with rcu_read_lock, so this code has been broken for a long time.
Both the mutex_lock and the usleep_range can cause the issue Ian Kumlien
reported[1]. The call path is:
be_ndo_bridge_getlink -> be_cmd_get_hsw_config -> be_mcc_notify_wait ->
be_mcc_wait_compl -> usleep_range()

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jiayuan Chen <jiayuan.chen@linux.dev>
[ Upstream commit 4c2d14c40a68678d885eab4008a0129646805bae ]
Syzbot caught an "KMSAN: uninit-value" warning [1], which is caused by the
ppp driver not initializing a 2-byte header when using socket filter.
The following code can generate a PPP filter BPF program:
'''
struct bpf_program fp;
pcap_t *handle;
handle = pcap_open_dead(DLT_PPP_PPPD, 65535);
pcap_compile(handle, &fp, "ip and outbound", 0, 0);
bpf_dump(&fp, 1);
'''
Its output is:
'''
(000) ldh [2]
(001) jeq #0x21 jt 2 jf 5
(002) ldb [0]
(003) jeq #0x1 jt 4 jf 5
(004) ret #65535
(005) ret #0
'''
Wen can find similar code at the following link:
https://github.com/ppp-project/ppp/blob/master/pppd/options.c#L1680
The maintainer of this code repository is also the original maintainer
of the ppp driver.
As you can see the BPF program skips 2 bytes of data and then reads the
'Protocol' field to determine if it's an IP packet. Then it read the first
byte of the first 2 bytes to determine the direction.
The issue is that only the first byte indicating direction is initialized
in current ppp driver code while the second byte is not initialized.
For normal BPF programs generated by libpcap, uninitialized data won't be
used, so it's not a problem. However, for carefully crafted BPF programs,
such as those generated by syzkaller [2], which start reading from offset
0, the uninitialized data will be used and caught by KMSAN.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Oscar Maes <oscmaes92@gmail.com>
[ Upstream commit b33a534610067ade2bdaf2052900aaad99701353 ]
Currently, VLAN devices can be created on top of non-ethernet devices.
Besides the fact that it doesn't make much sense, this also causes a
bug which leaks the address of a kernel function to usermode.
When creating a VLAN device, we initialize GARP (garp_init_applicant)
and MRP (mrp_init_applicant) for the underlying device.
As part of the initialization process, we add the multicast address of
each applicant to the underlying device, by calling dev_mc_add.
__dev_mc_add uses dev->addr_len to determine the length of the new
multicast address.
This causes an out-of-bounds read if dev->addr_len is greater than 6,
since the multicast addresses provided by GARP and MRP are only 6
bytes long.
This behaviour can be reproduced using the following commands:
ip tunnel add gretest mode ip6gre local ::1 remote ::2 dev lo
ip l set up dev gretest
ip link add link gretest name vlantest type vlan id 100
Then, the following command will display the address of garp_pdu_rcv:
ip maddr show | grep 01:80:c2:00:00:21
Fix the bug by enforcing the type of the underlying device during VLAN
device initialization.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jason Xing <kerneljasonxing@gmail.com>
[ Upstream commit 3c9231ea6497dfc50ac0ef69fff484da27d0df66 ]
When I read through the TSO codes, I found out that we probably
miss initializing the tx_flags of last seg when TSO is turned
off, which means at the following points no more timestamp
(for this last one) will be generated. There are three flags
to be handled in this patch:
1. SKBTX_HW_TSTAMP
2. SKBTX_BPF
3. SKBTX_SCHED_TSTAMP
Note that SKBTX_BPF[1] was added in 6.14.0-rc2 by commit
6b98ec7e882af ("bpf: Add BPF_SOCK_OPS_TSTAMP_SCHED_CB callback")
and only belongs to net-next branch material for now. The common
issue of the above three flags can be fixed by this single patch.
This patch initializes the tx_flags to SKBTX_ANY_TSTAMP like what
the UDP GSO does to make the newly segmented last skb inherit the
tx_flags so that requested timestamp will be generated in each
certain layer, or else that last one has zero value of tx_flags
which leads to no timestamp at all.

------------------
From: Christian Heusel <christian@heusel.eu>
commit 2397d61ee45cddb8f3bd3a3a9840ef0f0b5aa843 upstream.
This reverts commit 235b630eda072d7e7b102ab346d6b8a2c028a772.
This commit was found responsible for issues with SD card recognition,
as users had to re-insert their cards in the readers and wait for a
while. As for some people the SD card was involved in the boot process
it also caused boot failures.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nikita Zhandarovich <n.zhandarovich@fintech.ru>
commit c90aad369899a607cfbc002bebeafd51e31900cd upstream.
Syzbot once again identified a flaw in usb endpoint checking, see [1].
This time the issue stems from a commit authored by me (2eabb655a968
("usb: atm: cxacru: fix endpoint checking in cxacru_bind()")).
While using usb_find_common_endpoints() may usually be enough to
discard devices with wrong endpoints, in this case one needs more
than just finding and identifying the sufficient number of endpoints
of correct types - one needs to check the endpoint's address as well.
Since cxacru_bind() fills URBs with CXACRU_EP_CMD address in mind,
switch the endpoint verification approach to usb_check_XXX_endpoints()
instead to fix incomplete ep testing.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Fedor Pchelkin <boddah8794@gmail.com>
commit bf4f9ae1cb08ccaafbe6874be6c46f59b83ae778 upstream.
It is observed that on some systems an initial PPM reset during the boot
phase can trigger a timeout:
[ 6.482546] ucsi_acpi USBC000:00: failed to reset PPM!
[ 6.482551] ucsi_acpi USBC000:00: error -ETIMEDOUT: PPM init failed
Still, increasing the timeout value, albeit being the most straightforward
solution, eliminates the problem: the initial PPM reset may take up to
~8000-10000ms on some Lenovo laptops. When it is reset after the above
period of time (or even if ucsi_reset_ppm() is not called overall), UCSI
works as expected.
Moreover, if the ucsi_acpi module is loaded/unloaded manually after the
system has booted, reading the CCI values and resetting the PPM works
perfectly, without any timeout. Thus it's only a boot-time issue.
The reason for this behavior is not clear but it may be the consequence
of some tricks that the firmware performs or be an actual firmware bug.
As a workaround, increase the timeout to avoid failing the UCSI
initialization prematurely.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>
commit d6b82dafd17db0658f089b9cdec573982ca82bc5 upstream.
During probe, the TCPC alert interrupts are getting masked to
avoid unwanted interrupts during chip setup: this is ok to do
but there is no unmasking happening at any later time, which
means that the chip will not raise any interrupt, essentially
making it not functional as, while internally it does perform
all of the intended functions, it won't signal anything to the
outside.
Unmask the alert interrupts to fix functionality.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Prashanth K <prashanth.k@oss.qualcomm.com>
commit 40e89ff5750fca2c1d6da93f98a2038716bba86c upstream.
Currently the USB gadget will be set as bus-powered based solely
on whether its bMaxPower is greater than 100mA, but this may miss
devices that may legitimately draw less than 100mA but still want
to report as bus-powered. Similarly during suspend & resume, USB
gadget is incorrectly marked as bus/self powered without checking
the bmAttributes field. Fix these by configuring the USB gadget
as self or bus powered based on bmAttributes, and explicitly set
it as bus-powered if it draws more than 100mA.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Phillip Lougher <phillip@squashfs.org.uk>
commit 9253c54e01b6505d348afbc02abaa4d9f8a01395 upstream.
Syskiller has produced an out of bounds access in fill_meta_index().
That out of bounds access is ultimately caused because the inode
has an inode number with the invalid value of zero, which was not checked.
The reason this causes the out of bounds access is due to following
sequence of events:
1. Fill_meta_index() is called to allocate (via empty_meta_index())
and fill a metadata index. It however suffers a data read error
and aborts, invalidating the newly returned empty metadata index.
It does this by setting the inode number of the index to zero,
which means unused (zero is not a valid inode number).
2. When fill_meta_index() is subsequently called again on another
read operation, locate_meta_index() returns the previous index
because it matches the inode number of 0. Because this index
has been returned it is expected to have been filled, and because
it hasn't been, an out of bounds access is performed.
This patch adds a sanity check which checks that the inode number
is not zero when the inode is created and returns -EINVAL if it is.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Visweswara Tanuku <quic_vtanuku@quicinc.com>
commit dcb0d43ba8eb9517e70b1a0e4b0ae0ab657a0e5a upstream.
In case of interrupt delay for any reason, slim_do_transfer()
returns timeout error but the transaction ID (TID) is not freed.
This results into invalid memory access inside
qcom_slim_ngd_rx_msgq_cb() due to invalid TID.
Fix the issue by freeing the TID in slim_do_transfer() before
returning timeout error to avoid invalid memory access.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
commit 038ef0754aae76f79b147b8867f9250e6a976872 upstream.
The dev_id value in the GPIO lookup table must match to
the device instance name, which in this case is combined
of name and platform device ID, i.e. "spi_gpio.1". But
the table assumed that there was no platform device ID
defined, which is wrong. Fix the dev_id value accordingly.
