6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jann Horn <jannh@google.com>
commit 3cad1bc010416c6dd780643476bc59ed742436b9 upstream.
When fcntl_setlk() races with close(), it removes the created lock with
do_lock_file_wait().
However, LSMs can allow the first do_lock_file_wait() that created the lock
while denying the second do_lock_file_wait() that tries to remove the lock.
In theory (but AFAIK not in practice), posix_lock_file() could also fail to
remove a lock due to GFP_KERNEL allocation failure (when splitting a range
in the middle).
After the bug has been triggered, use-after-free reads will occur in
lock_get_status() when userspace reads /proc/locks. This can likely be used
to read arbitrary kernel memory, but can't corrupt kernel memory.
This only affects systems with SELinux / Smack / AppArmor / BPF-LSM in
enforcing mode and only works from some security contexts.
Fix it by calling locks_remove_posix() instead, which is designed to
reliably get rid of POSIX locks associated with the given file and
files_struct and is also used by filp_flush().
Fixes: c293621bbf67 ("[PATCH] stale POSIX lock handling")

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Martin Wilck <martin.wilck@suse.com>
[ Upstream commit 10157b1fc1a762293381e9145041253420dfc6ad ]
When a host is configured with a few LUNs and I/O is running, injecting FC
faults repeatedly leads to path recovery problems. The LUNs have 4 paths
each and 3 of them come back active after say an FC fault which makes 2 of
the paths go down, instead of all 4. This happens after several iterations
of continuous FC faults.
Reason here is that we're returning an I/O error whenever we're
encountering sense code 06/04/0a (LOGICAL UNIT NOT ACCESSIBLE, ASYMMETRIC
ACCESS STATE TRANSITION) instead of retrying.
[mwilck: The original patch was developed by Rajashekhar M A and Hannes
Reinecke. I moved the code to alua_check_sense() as suggested by Mike
Christie [1]. Evan Milne had raised the question whether pg->state should
be set to transitioning in the UA case [2]. I believe that doing this is
correct. SCSI_ACCESS_STATE_TRANSITIONING by itself doesn't cause I/O
errors. Our handler schedules an RTPG, which will only result in an I/O
error condition if the transitioning timeout expires.]

Running syzkaller with the newly reintroduced signed integer overflow
sanitizer produces this report:

Historically, the signed integer overflow sanitizer did not work in the
kernel due to its interaction with `-fwrapv` but this has since been
changed [1] in the newest version of Clang. It was re-enabled in the kernel
with Commit 557f8c582a9b ("ubsan: Reintroduce signed overflow sanitizer").
Firstly, let's change the type of "speed" to unsigned long as
sr_select_speed()'s only caller passes in an unsigned long anyways.
$ git grep '\.select_speed'
| drivers/scsi/sr.c: .select_speed = sr_select_speed,
...
| static int cdrom_ioctl_select_speed(struct cdrom_device_info *cdi,
| unsigned long arg)
| {
| ...
| return cdi->ops->select_speed(cdi, arg);
| }
Next, let's add an extra check to make sure we don't exceed 0xffff/177
(350) since 0xffff is the max speed. This has two benefits: 1) we deal
with integer overflow before it happens and 2) we properly respect the
max speed of 0xffff. There are some "magic" numbers here but I did not
want to change more than what was necessary.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nathan Chancellor <nathan@kernel.org>
[ Upstream commit 5134acb15d9ef27aa2b90aad46d4e89fcef79fdc ]
When building ARCH=loongarch defconfig + CONFIG_UNWINDER_ORC=y using
LLVM, there is a warning from ld.lld when linking the EFI zboot image
due to the use of unreachable() in number() in vsprintf.c:
ld.lld: warning: drivers/firmware/efi/libstub/lib.a(vsprintf.stub.o):(.discard.unreachable+0x0): has non-ABS relocation R_LARCH_32_PCREL against symbol ''
If the compiler cannot eliminate the default case for any reason, the
.discard.unreachable section will remain in the final binary but the
entire point of any section prefixed with .discard is that it is only
used at compile time, so it can be discarded via /DISCARD/ in a linker
script. The asm-generic vmlinux.lds.h includes .discard and .discard.*
in the COMMON_DISCARDS macro but that is not used for zboot.lds, as it
is not a kernel image linker script.
Add .discard and .discard.* to /DISCARD/ in zboot.lds, so that any
sections meant to be discarded at link time are not included in the
final zboot image. This issue is not specific to LoongArch, it is just
the first architecture to select CONFIG_OBJTOOL, which defines
annotate_unreachable() as an asm statement to add the
.discard.unreachable section, and use the EFI stub.

Abort such operations if a single call to acpi_ec_read() /

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nicolas Escande <nico.escande@gmail.com>
[ Upstream commit 6f6291f09a322c1c1578badac8072d049363f4e6 ]
With a ath9k device I can see that:
iw phy phy0 interface add mesh0 type mp
ip link set mesh0 up
iw dev mesh0 scan
Will start a scan with the Power Management bit set in the Frame Control Field.
This is because we set this bit depending on the nonpeer_pm variable of the mesh
iface sdata and when there are no active links on the interface it remains to
NL80211_MESH_POWER_UNKNOWN.
As soon as links starts to be established, it wil switch to
NL80211_MESH_POWER_ACTIVE as it is the value set by befault on the per sta
nonpeer_pm field.
As we want no power save by default, (as expressed with the per sta ini values),
lets init it to the expected default value of NL80211_MESH_POWER_ACTIVE.
Also please note that we cannot change the default value from userspace prior to
establishing a link as using NL80211_CMD_SET_MESH_CONFIG will not work before
NL80211_CMD_JOIN_MESH has been issued. So too late for our initial scan.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johannes Berg <johannes.berg@intel.com>
[ Upstream commit 177c6ae9725d783f9e96f02593ce8fb2639be22f ]
The code itself doesn't want to handle frames from the driver
if it's already stopped, but if the tasklet was queued before
and runs after the stop, then all bets are off. Flush queues
before actually stopping, RX should be off at this point since
all the interfaces are removed already, etc.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johannes Berg <johannes.berg@intel.com>
[ Upstream commit f7a8b10bfd614d7a9a16fbe80d28ead4f063cb00 ]
The 6 GHz scan request struct allocated by cfg80211_scan_6ghz() is
meant to be formed this way:
[base struct][channels][ssids][6ghz_params]
It is allocated with [channels] as the maximum number of channels
supported by the driver in the 6 GHz band, since allocation is
before knowing how many there will be.
However, the inner pointers are set incorrectly: initially, the
6 GHz scan parameters pointer is set:
[base struct][channels]
^ scan_6ghz_params
and later the SSID pointer is set to the end of the actually
_used_ channels.
[base struct][channels]
^ ssids
If many APs were to be discovered, and many channels used, and
there were many SSIDs, then the SSIDs could overlap the 6 GHz
parameters.
Additionally, the request->ssids for most of the function points
to the original request still (given the struct copy) but is used
normally, which is confusing.
Clear this up, by actually using the allocated space for 6 GHz
parameters _after_ the SSIDs, and set up the SSIDs initially so
they are used more clearly. Just like in nl80211.c, set them
only if there actually are SSIDs though.
Finally, also copy the elements (ie/ie_len) so they're part of
the same request, not pointing to the old request.

[ Upstream commit b7ffca99313d856f7d1cc89038d9061b128e8e97 ]
After moving from commands to notificaitons in the d3 resume flow,
removing the WOWLAN_GET_STATUSES and REPLY_OFFLOADS_QUERY_CMD causes
the return of the default value when looking up their version.
Returning zero here results in the driver sending the not supported
NON_QOS_TX_COUNTER_CMD.

------------------
From: Benjamin Berg <benjamin.berg@intel.com>
[ Upstream commit cc3ba78f202de9752aceb16342ab62bdfbffac7e ]
If pre-recovery mac80211 tried to disable a link but this disablement
failed, then there might be a mismatch between mac80211 assuming the
link has been disabled and the driver still having the data around.
During recover itself, that is not a problem, but should the link be
activated again at a later point, iwlwifi will refuse the activation as
it detects the inconsistent state.
Solve this corner-case by iterating the station in the restart cleanup
handler.

[ Upstream commit 08b16d1b5997dc378533318e2a9cd73c7a898284 ]
The BIGTK cipher field was added to the kek_kck_material_cmd
but wasn't assigned. Fix that by differentiating between the
IGTK/BIGTK keys and assign the ciphers fields accordingly.

From: Johannes Berg <johannes.berg@intel.com>
[ Upstream commit 4d08c0b3357cba0aeffaf3abc62cae0c154f2816 ]
When entering RF-kill, mac80211 tears down BA sessions, but
due to RF-kill the commands aren't sent to the device. As a
result, there can be frames pending on the reorder buffer or
perhaps even received while doing so, leading to warnings.
Avoid the warnings by doing the BA session teardown normally
even in RF-kill, which also requires queue sync.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ilan Peer <ilan.peer@intel.com>
[ Upstream commit e6dd2936ce7ce94a1915b799f8af8193ec628e87 ]
When HW rfkill is toggled to disable the RF, the flow to stop scan is
called. When trying to send the command to abort the scan, since
HW rfkill is toggled, the command is not sent due to rfkill being
asserted, and -ERFKILL is returned from iwl_trans_send_cmd(), but this
is silently ignored in iwl_mvm_send_cmd() and thus the scan abort flow
continues to wait for scan complete notification and fails. Since it
fails, the UID to type mapping is not cleared, and thus a warning is
later fired when trying to stop the interface.
To fix this, modify the UMAC scan abort flow to force sending the
scan abort command even when in rfkill, so stop the FW from accessing
the radio etc.

From: Dmitry Antipov <dmantipov@yandex.ru>
[ Upstream commit 92ecbb3ac6f3fe8ae9edf3226c76aa17b6800699 ]
When testing the previous patch with CONFIG_UBSAN_BOUNDS, I've
noticed the following:
UBSAN: array-index-out-of-bounds in net/mac80211/scan.c:372:4
index 0 is out of range for type 'struct ieee80211_channel *[]'
CPU: 0 PID: 1435 Comm: wpa_supplicant Not tainted 6.9.0+ #1

...<the rest is not too useful...>
Since '__ieee80211_start_scan()' leaves 'hw_scan_req->req.n_channels'
uninitialized, actual boundaries of 'hw_scan_req->req.channels' can't
be checked in 'ieee80211_prep_hw_scan()'. Although an initialization
of 'hw_scan_req->req.n_channels' introduces some confusion around
allocated vs. used VLA members, this shouldn't be a problem since
everything is correctly adjusted soon in 'ieee80211_prep_hw_scan()'.
Cleanup 'kmalloc()' math in '__ieee80211_start_scan()' by using the
convenient 'struct_size()' as well.

------------------
From: John Hubbard <jhubbard@nvidia.com>
[ Upstream commit cb708ab9f584f159798b60853edcf0c8b67ce295 ]
It's slightly better to set _GNU_SOURCE in the source code, but if one
must do it via the compiler invocation, then the best way to do so is
this:
$(CC) -D_GNU_SOURCE=
...because otherwise, if this form is used:
$(CC) -D_GNU_SOURCE
...then that leads the compiler to set a value, as if you had passed in:
$(CC) -D_GNU_SOURCE=1
That, in turn, leads to warnings under both gcc and clang, like this:
futex_requeue_pi.c:20: warning: "_GNU_SOURCE" redefined
Fix this by using the "-D_GNU_SOURCE=" form.

------------------
From: Rob Herring (Arm) <robh@kernel.org>
[ Upstream commit 935df1bd40d43c4ee91838c42a20e9af751885cc ]
Factor out the parsing of interrupt-map interrupt parent phandle and its
arg cells to a separate function, of_irq_parse_imap_parent(), so that it
can be used in other parsing scenarios (e.g. fw_devlink).
There was a refcount leak on non-matching entries when iterating thru
"interrupt-map" which is fixed.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hans de Goede <hdegoede@redhat.com>
[ Upstream commit 38a38f5a36da9820680d413972cb733349400532 ]
When support for Silead touchscreens was orginal added some touchscreens
with older firmware versions only supported 5 fingers and this was made
the default requiring the setting of a "silead,max-fingers=10" uint32
device-property for all touchscreen models which do support 10 fingers.
There are very few models with the old 5 finger fw, so in practice the
setting of the "silead,max-fingers=10" is boilerplate which needs to
be copy and pasted to every touchscreen config.
Reporting that 10 fingers are supported on devices which only support
5 fingers doesn't cause any problems for userspace in practice, since
at max 4 finger gestures are supported anyways. Drop the max_fingers
configuration and simply always assume 10 fingers.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Dumazet <edumazet@google.com>
[ Upstream commit db0090c6eb12c31246438b7fe2a8f1b833e7a653 ]
As explained in commit 1378817486d6 ("tipc: block BH
before using dst_cache"), net/core/dst_cache.c
helpers need to be called with BH disabled.
Disabling preemption in rpl_output() is not good enough,
because rpl_output() is called from process context,
lwtunnel_output() only uses rcu_read_lock().
We might be interrupted by a softirq, re-enter rpl_output()
and corrupt dst_cache data structures.
Fix the race by using local_bh_disable() instead of
preempt_disable().
Apply a similar change in rpl_input().

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Dumazet <edumazet@google.com>
[ Upstream commit cf28ff8e4c02e1ffa850755288ac954b6ff0db8c ]
As explained in commit 1378817486d6 ("tipc: block BH
before using dst_cache"), net/core/dst_cache.c
helpers need to be called with BH disabled.
ila_output() is called from lwtunnel_output()
possibly from process context, and under rcu_read_lock().
We might be interrupted by a softirq, re-enter ila_output()
and corrupt dst_cache data structures.
Fix the race by using local_bh_disable().

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wei Li <liwei391@huawei.com>
[ Upstream commit 14951beaec93696b092a906baa0f29322cf34004 ]
The function run_all_insn_set_hw_mode() is registered as startup callback
of 'CPUHP_AP_ARM64_ISNDEP_STARTING', it invokes set_hw_mode() methods of
all emulated instructions.
As the STARTING callbacks are not expected to fail, if one of the
set_hw_mode() fails, e.g. due to el0 mixed-endian is not supported for
'setend', it will report a warning:
```
CPU[2] cannot support the emulation of setend
CPU 2 UP state arm64/isndep:starting (136) failed (-22)
CPU2: Booted secondary processor 0x0000000002 [0x414fd0c1]
```
To fix it, add a check for INSN_UNAVAILABLE status and skip the process.

Currently, the initial state of the "Save" button is always active.
If none of the CONFIG options are changed while loading the .config
file, the "Save" button should be greyed out.
This can be fixed by calling conf_read() after widget initialization.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Masahiro Yamada <masahiroy@kernel.org>
[ Upstream commit 77a92660d8fe8d29503fae768d9f5eb529c88b36 ]
expr_trans_bool() performs an incorrect transformation.
[Test Code]
config MODULES
def_bool y
modules
config A
def_bool y
select C if B != n
config B
def_tristate m
config C
tristate
[Result]
CONFIG_MODULES=y
CONFIG_A=y
CONFIG_B=m
CONFIG_C=m
This output is incorrect because CONFIG_C=y is expected.
Documentation/kbuild/kconfig-language.rst clearly explains the function
of the '!=' operator:
If the values of both symbols are equal, it returns 'n',
otherwise 'y'.
Therefore, the statement:
select C if B != n
should be equivalent to:
select C if y
Or, more simply:
select C
Hence, the symbol C should be selected by the value of A, which is 'y'.
However, expr_trans_bool() wrongly transforms it to:
select C if B
Therefore, the symbol C is selected by (A && B), which is 'm'.
The comment block of expr_trans_bool() correctly explains its intention:
* bool FOO!=n => FOO
^^^^
If FOO is bool, FOO!=n can be simplified into FOO. This is correct.
However, the actual code performs this transformation when FOO is
tristate:
if (e->left.sym->type == S_TRISTATE) {
^^^^^^^^^^
While it can be fixed to S_BOOLEAN, there is no point in doing so
because expr_tranform() already transforms FOO!=n to FOO when FOO is
bool. (see the "case E_UNEQUAL" part)
expr_trans_bool() is wrong and unnecessary.

From: Louis Dalibard <ontake@ontake.dev>
[ Upstream commit a3a5a37efba11b7cf1a86abe7bccfbcdb521764e ]
At least ASUS Zenbook 14 (2023) and ASUS Zenbook 14 Pro (2023) are affected.
The touchscreen reports a battery status of 0% and jumps to 1% when a
stylus is used.
The device ID was added and the battery ignore quirk was enabled for it.

There is an inherent race where a symlink file may have been overriden
(by a different client) between lookup and readlink, resulting in a
spurious EIO error returned to userspace. Fix this by propagating back
ESTALE errors such that the vfs will retry the lookup/get_link (similar
to nfs4_file_open) at least once.

------------------
From: Jan Kara <jack@suse.cz>
[ Upstream commit a527c3ba41c4c61e2069bfce4091e5515f06a8dd ]
When we are doing WB_SYNC_ALL writeback, nfs submits write requests with
NFS_FILE_SYNC flag to the server (which then generally treats it as an
O_SYNC write). This helps to reduce latency for single requests but when
submitting more requests, additional fsyncs on the server side hurt
latency. NFS generally avoids this additional overhead by not setting
NFS_FILE_SYNC if desc->pg_moreio is set.
However this logic doesn't always work. When we do random 4k writes to a huge
file and then call fsync(2), each page writeback is going to be sent with
NFS_FILE_SYNC because after preparing one page for writeback, we start writing
back next, nfs_do_writepage() will call nfs_pageio_cond_complete() which finds
the page is not contiguous with previously prepared IO and submits is *without*
setting desc->pg_moreio. Hence NFS_FILE_SYNC is used resulting in poor
performance.
Fix the problem by setting desc->pg_moreio in nfs_pageio_cond_complete() before
submitting outstanding IO. This improves throughput of
fsync-after-random-writes on my test SSD from ~70MB/s to ~250MB/s.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Scott Mayhew <smayhew@redhat.com>
[ Upstream commit 0c8c7c559740d2d8b66048162af6c4dba8f0c88c ]
This is a slight variation on a patch previously proposed by Neil Brown
that never got merged.
Prior to commit 5ceb9d7fdaaf ("NFS: Refactor nfs_lookup_revalidate()"),
any error from nfs_lookup_verify_inode() other than -ESTALE would result
in nfs_lookup_revalidate() returning that error (-ESTALE is mapped to
zero).
Since that commit, all errors result in nfs_lookup_revalidate()
returning zero, resulting in dentries being invalidated where they
previously were not (particularly in the case of -ERESTARTSYS).
Fix it by passing the actual error code to nfs_lookup_revalidate_done(),
and leaving the decision on whether to map the error code to zero or
one to nfs_lookup_revalidate_done().
A simple reproducer is to run the following python code in a
subdirectory of an NFS mount (not in the root of the NFS mount):
---8<---
import os
import multiprocessing
import time
if __name__=="__main__":
multiprocessing.set_start_method("spawn")
count = 0
while True:
try:
os.getcwd()
pool = multiprocessing.Pool(10)
pool.close()
pool.terminate()
count += 1
except Exception as e:
print(f"Failed after {count} iterations")
print(e)
break
---8<---
Prior to commit 5ceb9d7fdaaf, the above code would run indefinitely.
After commit 5ceb9d7fdaaf, it fails almost immediately with -ENOENT.

[ Upstream commit a26dc49df37e996876f50a0210039b2d211fdd6f ]
This prevents malicious processes from completing random copen/cread
requests and crashing the system. Added checks are listed below:
* Generic, copen can only complete open requests, and cread can only
complete read requests.
* For copen, ondemand_id must not be 0, because this indicates that the
request has not been read by the daemon.
* For cread, the object corresponding to fd and req should be the same.

[ Upstream commit 4f8703fb3482f92edcfd31661857b16fec89c2c0 ]
If copen is maliciously called in the user mode, it may delete the request
corresponding to the random id. And the request may have not been read yet.
Note that when the object is set to reopen, the open request will be done
with the still reopen state in above case. As a result, the request
corresponding to this object is always skipped in select_req function, so
the read request is never completed and blocks other process.
Fix this issue by simply set object to close if its id < 0 in copen.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Baokun Li <libaokun1@huawei.com>
[ Upstream commit bc9dde6155464e906e630a0a5c17a4cab241ffbb ]
Replacing wait_for_completion() with wait_for_completion_killable() in
cachefiles_ondemand_send_req() allows us to kill processes that might
trigger a hunk_task if the daemon is abnormal.
But now only CACHEFILES_OP_READ is killable, because OP_CLOSE and OP_OPEN
is initiated from kworker context and the signal is prohibited in these
kworker.
Note that when the req in xas changes, i.e. xas_load(&xas) != req, it
means that a process will complete the current request soon, so wait
again for the request to be completed.
In addition, add the cachefiles_ondemand_finish_req() helper function to
simplify the code.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yuntao Wang <yuntao.wang@linux.dev>
[ Upstream commit ed8c7fbdfe117abbef81f65428ba263118ef298a ]
The maximum possible return value of find_next_zero_bit(fdt->full_fds_bits,
maxbit, bitbit) is maxbit. This return value, multiplied by BITS_PER_LONG,
gives the value of bitbit, which can never be greater than maxfd, it can
only be equal to maxfd at most, so the following check 'if (bitbit > maxfd)'
will never be true.
Moreover, when bitbit equals maxfd, it indicates that there are no unused
fds, and the function can directly return.
Fix this check.

From: Alexander Usyskin <alexander.usyskin@intel.com>
[ Upstream commit 1db5322b7e6b58e1b304ce69a50e9dca798ca95b ]
Change level for the "not connected" client message in the write
callback from error to debug.
The MEI driver currently disconnects all clients upon system suspend.
This behavior is by design and user-space applications with
open connections before the suspend are expected to handle errors upon
resume, by reopening their handles, reconnecting,
and retrying their operations.
However, the current driver implementation logs an error message every
time a write operation is attempted on a disconnected client.
Since this is a normal and expected flow after system resume
logging this as an error can be misleading.

From: Ritesh Harjani (IBM) <ritesh.list@gmail.com>
[ Upstream commit f5ceb1bbc98c69536d4673a97315e8427e67de1b ]
If the extent spans the block that contains i_size, we need to handle
both halves separately so that we properly zero data in the page cache
for blocks that are entirely outside of i_size. But this is needed only
when i_size is within the current folio under processing.
"orig_pos + length > isize" can be true for all folios if the mapped
extent length is greater than the folio size. That is making plen to
break for every folio instead of only the last folio.
So use orig_plen for checking if "orig_pos + orig_plen > isize".

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Douglas Anderson <dianders@chromium.org>
[ Upstream commit c38896ca6318c2df20bbe6c8e3f633e071fda910 ]
Based on grepping through the source code this driver appears to be
missing a call to drm_atomic_helper_shutdown() at system shutdown
time. Among other things, this means that if a panel is in use that it
won't be cleanly powered off at system shutdown time.
The fact that we should call drm_atomic_helper_shutdown() in the case
of OS shutdown/restart comes straight out of the kernel doc "driver
instance overview" in drm_drv.c.
This driver users the component model and shutdown happens in the base
driver. The "drvdata" for this driver will always be valid if
shutdown() is called and as of commit 2a073968289d
("drm/atomic-helper: drm_atomic_helper_shutdown(NULL) should be a
noop") we don't need to confirm that "drm" is non-NULL.

From: Chunguang Xu <chunguang.xu@shopee.com>
[ Upstream commit e5d574ab37f5f2e7937405613d9b1a724811e5ad ]
If a discard request needs to be retried, and that retry may fail before
a new special payload is added, a double free will result. Clear the
RQF_SPECIAL_LOAD when the request is cleaned.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Daniel Wagner <dwagner@suse.de>
[ Upstream commit cd0c1b8e045a8d2785342b385cb2684d9b48e426 ]
The spec doesn't mandate that the first two double words (aka results)
for the command queue entry need to be set to 0 when they are not
used (not specified). Though, the target implemention returns 0 for TCP
and FC but not for RDMA.
Let's make RDMA behave the same and thus explicitly initializing the
result field. This prevents leaking any data from the stack.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michael Ellerman <mpe@ellerman.id.au>
[ Upstream commit a986fa57fd81a1430e00b3c6cf8a325d6f894a63 ]
Al reported a possible use-after-free (UAF) in kvm_spapr_tce_attach_iommu_group().
It looks up `stt` from tablefd, but then continues to use it after doing
fdput() on the returned fd. After the fdput() the tablefd is free to be
closed by another thread. The close calls kvm_spapr_tce_release() and
then release_spapr_tce_table() (via call_rcu()) which frees `stt`.
Although there are calls to rcu_read_lock() in
kvm_spapr_tce_attach_iommu_group() they are not sufficient to prevent
the UAF, because `stt` is used outside the locked regions.
With an artifcial delay after the fdput() and a userspace program which
triggers the race, KASAN detects the UAF:

Fix it by delaying the fdput() until `stt` is no longer in use, which
is effectively the entire function. To keep the patch minimal add a call
to fdput() at each of the existing return paths. Future work can convert
the function to goto or __cleanup style cleanup.
With the fix in place the test case no longer triggers the UAF.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Linus Torvalds <torvalds@linux-foundation.org>
[ Upstream commit 5d272dd1b3430bb31fa30042490fa081512424e4 ]
Hardcoding the number of CPUs at compile time does improve code
generation, but if you get it wrong the result will be confusion.
We already limited this earlier to only "experts" (see commit
fe5759d5bfda "cpumask: limit visibility of FORCE_NR_CPUS"), but with
distro kernel configs often having EXPERT enabled, that turns out to not
be much of a limit.
To quote the philosophers at Disney: "Everyone can be an expert. And
when everyone's an expert, no one will be".
There's a runtime warning if you then set nr_cpus to anything but the
forced number, but apparently that can be ignored too [1] and by then
it's pretty much too late anyway.
If we had some real way to limit this to "embedded only", maybe it would
be worth it, but let's see if anybody even notices that the option is
gone. We need to simplify kernel configuration anyway.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Simon Trimmer <simont@opensource.cirrus.com>
[ Upstream commit 9b1effff19cdf2230d3ecb07ff4038a0da32e9cc ]
The ACPI IDs used in the CS35L56 HDA drivers are all handled by the
serial multi-instantiate driver which starts multiple Linux device
instances from a single ACPI Device() node.
As serial multi-instantiate is not an optional part of the system add it
as a dependency in Kconfig so that it is not overlooked.

Hi Greg,
(As remarked on 6.9-stable) Takashi made a corrective patch to this one as
there were some build problems -

From: Arnd Bergmann <arnd@arndb.de>
[ Upstream commit 0d5679a0aae2d8cda72169452c32e5cb88a7ab33 ]
This is almost compatible, but passing a negative offset should result
in a EINVAL error, but on mips o32 compat mode would seek to a large
32-bit byte offset.
Use compat_sys_lseek() to correctly sign-extend the argument.

------------------
From: Jonathan Denose <jdenose@google.com>
[ Upstream commit a69ce592cbe0417664bc5a075205aa75c2ec1273 ]
The Lenovo N24 on resume becomes stuck in a state where it
sends incorrect packets, causing elantech_packet_check_v4 to fail.
The only way for the device to resume sending the correct packets is for
it to be disabled and then re-enabled.
This change adds a dmi check to trigger this behavior on resume.

[ Upstream commit 97ab304ecd95c0b1703ff8c8c3956dc6e2afe8e1 ]
Most users after parsing a topology file, release memory used by it, so
having pointer references directly into topology file contents is wrong.
Use devm_kmemdup(), to allocate memory as needed.

------------------
From: Jai Luthra <j-luthra@ti.com>
[ Upstream commit e8343410ddf08fc36a9b9cc7c51a4e53a262d4c6 ]
Sometimes the stream may be stopped due to XRUN events, in which case
the userspace can call snd_pcm_drop() and snd_pcm_prepare() to stop and
start the stream again.
In these cases, we must wait for the DMA channel to synchronize before
marking the stream as prepared for playback, as the DMA channel gets
stopped by drop() without any synchronization. Make sure the ALSA core
synchronizes the DMA channel by adding a sync_stop() hook.

From: Jai Luthra <j-luthra@ti.com>
[ Upstream commit c5dcf8ab10606e76c1d8a0ec77f27d84a392e874 ]
The minimum period size was enforced to 64 as older devices integrating
McASP with EDMA used an internal FIFO of 64 samples.
With UDMA based platforms this internal McASP FIFO is optional, as the
DMA engine internally does some buffering which is already accounted for
when registering the platform. So we should read the actual FIFO
configuration (txnumevt/rxnumevt) instead of hardcoding frames.min to
64.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Peter Ujfalusi <peter.ujfalusi@linux.intel.com>
[ Upstream commit 6f2a43e3d14f6e31a3b041a1043195d02c54d615 ]
If the ipc_prepare() callback fails for a module instance, on error rewind
we must skip the ipc_unprepare() call for ones that has positive use count.
The positive use count means that the module instance is in active use, it
cannot be unprepared.
The issue affects capture direction paths with branches (single dai with
multiple PCMs), the affected widgets are in the shared part of the paths.

As the driver supports more devices over time the single MODULE_ALIAS
is complete and raises several warnings:
SPI driver ads7846 has no spi_device_id for ti,tsc2046
SPI driver ads7846 has no spi_device_id for ti,ads7843
SPI driver ads7846 has no spi_device_id for ti,ads7845
SPI driver ads7846 has no spi_device_id for ti,ads7873
Fix this by adding a spi_device_id table and removing the manual
MODULE_ALIAS.

From: Ian Ray <ian.ray@gehealthcare.com>
[ Upstream commit bfc6444b57dc7186b6acc964705d7516cbaf3904 ]
Ensure that `i2c_lock' is held when setting interrupt latch and mask in
pca953x_irq_bus_sync_unlock() in order to avoid races.
The other (non-probe) call site pca953x_gpio_set_multiple() ensures the
lock is held before calling pca953x_write_regs().
The problem occurred when a request raced against irq_bus_sync_unlock()
approximately once per thousand reboots on an i.MX8MP based system.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Heiko Carstens <hca@linux.ibm.com>
[ Upstream commit 6434b33faaa063df500af355ee6c3942e0f8d982 ]
If sclp_init() fails it only partially cleans up: if there are multiple
failing calls to sclp_init() sclp_state_change_event will be added several
times to sclp_reg_list, which results in the following warning:
------------[ cut here ]------------

Fix this by removing sclp_state_change_event from sclp_reg_list when
sclp_init() fails.

From: Armin Wolf <W_Armin@gmx.de>
[ Upstream commit 151e78a0b89ee6dec93382dbdf5b1ef83f9c4716 ]
The LGEX0815 ACPI device is used by the "LG Airplane Mode Button"
Windows driver for handling rfkill requests. When the ACPI device
receives an 0x80 ACPI notification, an rfkill event is to be
send to userspace.
Add support for the LGEX0815 ACPI device to the driver.

From: Armin Wolf <W_Armin@gmx.de>
[ Upstream commit 413c204595ca98a4f33414a948c18d7314087342 ]
The rfkill hotkey handling is already provided by the wireless-hotkey
driver. Remove the now unnecessary rfkill hotkey handling to avoid
duplicating functionality.
The ACPI notify handler still prints debugging information when
receiving ACPI notifications to aid in reverse-engineering.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Armin Wolf <W_Armin@gmx.de>
[ Upstream commit 58a54f27a0dac81f7fd3514be01012635219a53c ]
The LGEX0815 ACPI device id is used for handling hotkey events, but
this functionality is already handled by the wireless-hotkey driver.
The LGEX0820 ACPI device id however is used to manage various
platform features using the WMAB/WMBB ACPI methods. Use this ACPI
device id to avoid blocking the wireless-hotkey driver from probing.

------------------
From: Armin Wolf <W_Armin@gmx.de>
[ Upstream commit b27ea279556121b54d3f45d0529706cf100cdb3a ]
On the LG Gram 16Z90S, the WMAB and WMBB ACPI methods are not mapped
under \XINI, but instead are mapped under \_SB.XINI.
The reason for this is that the LGEX0820 ACPI device used by this
driver is mapped at \_SB.XINI, so the ACPI methods where moved as well
to appear below the LGEX0820 ACPI device.
Fix this by using the ACPI handle from the ACPI device when evaluating
both methods.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Filipe Manana <fdmanana@suse.com>
[ Upstream commit a7e4c6a3031c74078dba7fa36239d0f4fe476c53 ]
If during the quota disable we fail when cleaning the quota tree or when
deleting the root from the root tree, we jump to the 'out' label without
ever dropping the reference on the quota root, resulting in a leak of the
root since fs_info->quota_root is no longer pointing to the root (we have
set it to NULL just before those steps).
Fix this by always doing a btrfs_put_root() call under the 'out' label.
This is a problem that exists since qgroups were first added in 2012 by
commit bed92eae26cc ("Btrfs: qgroup implementation and prototypes"), but
back then we missed a kfree on the quota root and free_extent_buffer()
calls on its root and commit root nodes, since back then roots were not
yet reference counted.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nick Child <nnac123@linux.ibm.com>
[ Upstream commit 0983d288caf984de0202c66641577b739caad561 ]
Below is a summary of how the driver stores a reference to an skb during
transmit:
tx_buff[free_map[consumer_index]]->skb = new_skb;
free_map[consumer_index] = IBMVNIC_INVALID_MAP;
consumer_index ++;
Where variable data looks like this:
free_map == [4, IBMVNIC_INVALID_MAP, IBMVNIC_INVALID_MAP, 0, 3]
consumer_index^
tx_buff == [skb=null, skb=<ptr>, skb=<ptr>, skb=null, skb=null]
The driver has checks to ensure that free_map[consumer_index] pointed to
a valid index but there was no check to ensure that this index pointed
to an unused/null skb address. So, if, by some chance, our free_map and
tx_buff lists become out of sync then we were previously risking an
skb memory leak. This could then cause tcp congestion control to stop
sending packets, eventually leading to ETIMEDOUT.
Therefore, add a conditional to ensure that the skb address is null. If
not then warn the user (because this is still a bug that should be
patched) and free the old pointer to prevent memleak/tcp problems.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Shengjiu Wang <shengjiu.wang@nxp.com>
[ Upstream commit 6a7db25aad8ce6512b366d2ce1d0e60bac00a09d ]
When dmaengine supports pause function, in suspend state,
dmaengine_pause() is called instead of dmaengine_terminate_async(),
In end of playback stream, the runtime->state will go to
SNDRV_PCM_STATE_DRAINING, if system suspend & resume happen
at this time, application will not resume playback stream, the
stream will be closed directly, the dmaengine_terminate_async()
will not be called before the dmaengine_synchronize(), which
violates the call sequence for dmaengine_synchronize().
This behavior also happens for capture streams, but there is no
SNDRV_PCM_STATE_DRAINING state for capture. So use
dmaengine_tx_status() to check the DMA status if the status is
DMA_PAUSED, then call dmaengine_terminate_async() to terminate
dmaengine before dmaengine_synchronize().

Commit 6d07d1cd300f ("usercopy: Restrict non-usercopy caches to size 0")
requires that only whitelisted areas in slab/slub objects can be copied to
userspace when usercopy hardening is enabled using CONFIG_HARDENED_USERCOPY.
Dtl contains hypervisor dispatch events which are expected to be read by
privileged users. Hence mark this safe for user access.
Specify useroffset=0 and usersize=DISPATCH_LOG_BYTES to whitelist the
entire object.

This patch use designated initializers for
'struct ffa_send_direct_data' to suppress the warning
and clarify the initialization intent.

From: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp>
[ Upstream commit 0d151a103775dd9645c78c97f77d6e2a5298d913 ]
syzbot is reporting that calling hci_release_dev() from hci_error_reset()
due to hci_dev_put() from hci_error_reset() can cause deadlock at
destroy_workqueue(), for hci_error_reset() is called from
hdev->req_workqueue which destroy_workqueue() needs to flush.
We need to make sure that hdev->{rx_work,cmd_work,tx_work} which are
queued into hdev->workqueue and hdev->{power_on,error_reset} which are
queued into hdev->req_workqueue are no longer running by the moment
destroy_workqueue(hdev->workqueue);
destroy_workqueue(hdev->req_workqueue);
are called from hci_release_dev().
Call cancel_work_sync() on these work items from hci_unregister_dev()
as soon as hdev->list is removed from hci_dev_list.

This sets the default power save mode setting to enabled.
The power save feature is now stable and stress test issues, such as the
TX timeout error, have been resolved.
commit c7ee0bc8db32 ("Bluetooth: btnxpuart: Resolve TX timeout error in

With this setting, the driver will send the vendor command to FW at

------------------
From: Edward Adam Davis <eadavis@qq.com>
[ Upstream commit 89e856e124f9ae548572c56b1b70c2255705f8fe ]
The problem occurs between the system call to close the sock and hci_rx_work,
where the former releases the sock and the latter accesses it without lock protection.
CPU0 CPU1
---- ----
sock_close hci_rx_work
l2cap_sock_release hci_acldata_packet
l2cap_sock_kill l2cap_recv_frame
sk_free l2cap_conless_channel
l2cap_sock_recv_cb
If hci_rx_work processes the data that needs to be received before the sock is
closed, then everything is normal; Otherwise, the work thread may access the
released sock when receiving data.
Add a chan mutex in the rx callback of the sock to achieve synchronization between
the sock release and recv cb.
Sock is dead, so set chan data to NULL, avoid others use invalid sock pointer.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gao Xiang <hsiangkao@linux.alibaba.com>
[ Upstream commit 9b32b063be1001e322c5f6e01f2a649636947851 ]
Sometimes, the on-disk metadata might be invalid due to user
interrupts, storage failures, or other unknown causes.
In that case, z_erofs_map_blocks_iter() may still return a valid
m_llen while other fields remain invalid (e.g., m_plen can be 0).
Due to the return value of z_erofs_scan_folio() in some path will
be ignored on purpose, the following z_erofs_scan_folio() could
then use the invalid value by accident.
Let's reset m_llen to 0 to prevent this.

[ Upstream commit 74ad26b36d303ac233eccadc5c3a8d7ee4709f31 ]
[Why]
We only enable the VRR while monitor usable refresh rate range
is greater than 10 Hz.
But we did not check the range in DRM_EDID_FEATURE_CONTINUOUS_FREQ
case.
[How]
Add a refresh rate range check before set the freesync_capable flag
in DRM_EDID_FEATURE_CONTINUOUS_FREQ case.

From: Alvin Lee <alvin.lee2@amd.com>
[ Upstream commit 074b3a886713f69d98d30bb348b1e4cb3ce52b22 ]
[Description]
We need to ensure to take into account cursor prefetch BW in
mode support or we may pass ModeQuery but fail an actual flip
which will cause a hang. Flip may fail because the cursor_pre_bw
is populated during mode programming (and mode programming is
never called prior to ModeQuery).

From: Tom Chung <chiahsuan.chung@amd.com>
[ Upstream commit 9ef1548aeaa8858e7aee2152bf95cc71cdcd6dff ]
[Why]
Some of the panels does not have the refresh rate range info
in base EDID and only have the refresh rate range info in
DisplayID block.
It will cause the max/min freesync refresh rate set to 0.
[How]
Try to parse the refresh rate range info from DisplayID if the
max/min refresh rate is 0.

------------------
From: Christian Brauner <brauner@kernel.org>
[ Upstream commit 391b59b045004d5b985d033263ccba3e941a7740 ]
Jan reported that 'cd ..' may take a long time in deep directory
hierarchies under a bind-mount. If concurrent renames happen it is
possible to livelock in is_subdir() because it will keep retrying.
Change is_subdir() from simply retrying over and over to retry once and
then acquire the rename lock to handle deep ancestor chains better. The
list of alternatives to this approach were less then pleasant. Change
the scope of rcu lock to cover the whole walk while at it.
A big thanks to Jan and Linus. Both Jan and Linus had proposed
effectively the same thing just that one version ended up being slightly
more elegant.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Samuel Holland <samuel.holland@sifive.com>
[ Upstream commit 7dd646cf745c34d31e7ed2a52265e9ca8308f58f ]
Currently, we stop all the counters while a new cpu is brought online.
However, the hpmevent to counter mappings are not reset. The firmware may
have some stale encoding in their mapping structure which may lead to
undesirable results. We have not encountered such scenario though.

------------------
From: Puranjay Mohan <puranjay@kernel.org>
[ Upstream commit 393da6cbb2ff89aadc47683a85269f913aa1c139 ]
ftrace_graph_ret_addr() takes an `idx` integer pointer that is used to
optimize the stack unwinding. Pass it a valid pointer to utilize the
optimizations that might be available in the future.
The commit is making riscv's usage of ftrace_graph_ret_addr() match
x86_64.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
[ Upstream commit ce1dac560a74220f2e53845ec0723b562288aed4 ]
While in commit 2dd33f9cec90 ("spi: imx: support DMA for imx35") it was
claimed that DMA works on i.MX25, i.MX31 and i.MX35 the respective
device trees don't add DMA channels. The Reference manuals of i.MX31 and
i.MX25 also don't mention the CSPI core being DMA capable. (I didn't
check the others.)
Since commit e267a5b3ec59 ("spi: spi-imx: Use dev_err_probe for failed
DMA channel requests") this results in an error message
spi_imx 43fa4000.spi: error -ENODEV: can't get the TX DMA channel!
during boot. However that isn't fatal and the driver gets loaded just
fine, just without using DMA.

When building with clang, via:
make LLVM=1 -C tools/testing/selftests
...clang warns about mismatches between the expected and required
integer length being supplied to abs(3).
Fix this by using the correct variant of abs(3): labs(3) or llabs(3), in
these cases.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: John Hubbard <jhubbard@nvidia.com>
[ Upstream commit 73810cd45b99c6c418e1c6a487b52c1e74edb20d ]
When building with clang, via:
make LLVM=1 -C tools/testing/selftests
...there are several warnings, and an error. This fixes all of those and
allows these tests to run and pass.
1. Fix linker error (undefined reference to memcpy) by providing a local
version of memcpy.
2. clang complains about using this form:
if (g = h & 0xf0000000)
...so factor out the assignment into a separate step.
3. The code is passing a signed const char* to elf_hash(), which expects
a const unsigned char *. There are several callers, so fix this at
the source by allowing the function to accept a signed argument, and
then converting to unsigned operations, once inside the function.
4. clang doesn't have __attribute__((externally_visible)) and generates
a warning to that effect. Fortunately, gcc 12 and gcc 13 do not seem
to require that attribute in order to build, run and pass tests here,
so remove it.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@suse.de>
[ Upstream commit 17563b4a19d1844bdbccc7a82d2f31c28ca9cfae ]
The recent fix introduced a reverse selection of
CONFIG_SERIAL_MULTI_INSTANTIATE, but its condition isn't always met.
Use a weak reverse selection to suggest the config for avoiding such
inconsistencies, instead.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Steve French <stfrench@microsoft.com>
commit ae4ccca47195332c69176b8615c5ee17efd30c46 upstream.
There are common cases where copy_file_range can noisily
log "source and target of copy not on same server"
e.g. the mv command across mounts to two different server's shares.
Change this to informational rather than logging as an error.
A followon patch will add dynamic trace points e.g. for
cifs_file_copychunk_range

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Masahiro Yamada <masahiroy@kernel.org>
commit 24d3ba0a7b44c1617c27f5045eecc4f34752ab03 upstream.
The 32-bit ARM kernel stops working if the kernel grows to the point
where veneers for __get_user_* are created.
AAPCS32 [1] states, "Register r12 (IP) may be used by a linker as a
scratch register between a routine and any subroutine it calls. It
can also be used within a routine to hold intermediate values between
subroutine calls."
However, bl instructions buried within the inline asm are unpredictable
for compilers; hence, "ip" must be added to the clobber list.
This becomes critical when veneers for __get_user_* are created because
veneers use the ip register since commit 02e541db0540 ("ARM: 8323/1:
force linker to use PIC veneers").

This BUG is the VM_BUG_ON(!in_atomic() && !irqs_disabled()) assertion in
folio_ref_try_add_rcu() for non-SMP kernel.
The process_vm_readv() calls GUP to pin the THP. An optimization for
pinning THP instroduced by commit 57edfcfd3419 ("mm/gup: accelerate thp
gup even for "pages != NULL"") calls try_grab_folio() to pin the THP,
but try_grab_folio() is supposed to be called in atomic context for
non-SMP kernel, for example, irq disabled or preemption disabled, due to
the optimization introduced by commit e286781d5f2e ("mm: speculative
page references").
The commit efa7df3e3bb5 ("mm: align larger anonymous mappings on THP
boundaries") is not actually the root cause although it was bisected to.
It just makes the problem exposed more likely.
The follow up discussion suggested the optimization for non-SMP kernel
may be out-dated and not worth it anymore [1]. So removing the
optimization to silence the BUG.
However calling try_grab_folio() in GUP slow path actually is
unnecessary, so the following patch will clean this up.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
commit f1a8f402f13f94263cf349216c257b2985100927 upstream.
This fixes the following deadlock introduced by 39a92a55be13
("bluetooth/l2cap: sync sock recv cb and release")
============================================
WARNING: possible recursive locking detected
6.10.0-rc3-g4029dba6b6f1 #6823 Not tainted
--------------------------------------------
kworker/u5:0/35 is trying to acquire lock:
ffff888002ec2510 (&chan->lock#2/1){+.+.}-{3:3}, at:
l2cap_sock_recv_cb+0x44/0x1e0
but task is already holding lock:
ffff888002ec2510 (&chan->lock#2/1){+.+.}-{3:3}, at:
l2cap_get_chan_by_scid+0xaf/0xd0
other info that might help us debug this:
Possible unsafe locking scenario:
CPU0
----
lock(&chan->lock#2/1);
lock(&chan->lock#2/1);
*** DEADLOCK ***
May be due to missing lock nesting notation
3 locks held by kworker/u5:0/35:
#0: ffff888002b8a940 ((wq_completion)hci0#2){+.+.}-{0:0}, at:
process_one_work+0x750/0x930
#1: ffff888002c67dd0 ((work_completion)(&hdev->rx_work)){+.+.}-{0:0},
at: process_one_work+0x44e/0x930
#2: ffff888002ec2510 (&chan->lock#2/1){+.+.}-{3:3}, at:
l2cap_get_chan_by_scid+0xaf/0xd0
To fix the original problem this introduces l2cap_chan_lock at
l2cap_conless_channel to ensure that l2cap_sock_recv_cb is called with
chan->lock held.

6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marc Zyngier <maz@kernel.org>
commit 2cf6b7d15a28640117bf9f75dc050892cf78a6e8 upstream.
Once again, we've broken PASEMI Nemo boards with its incomplete
"interrupt-map" translations. Commit 935df1bd40d4 ("of/irq: Factor out
parsing of interrupt-map parent phandle+args from of_irq_parse_raw()")
changed the behavior resulting in the existing work-around not taking
effect. Rework the work-around to just skip parsing "interrupt-map" up
front by using the of_irq_imap_abusers list.
Fixes: 935df1bd40d4 ("of/irq: Factor out parsing of interrupt-map parent phandle+args from of_irq_parse_raw()")

------------------
From: Johannes Berg <johannes.berg@intel.com>
commit 0941772342d59e48733131ac3a202fa1a4d832e9 upstream.
In nl80211, we always set the ssids of a scan request to
NULL when n_ssids==0 (passive scan). Drivers have relied
on this behaviour in the past, so we fixed it in 6 GHz
scan requests as well, and added a warning so we'd have
assurance the API would always be called that way.
syzbot found that wext doesn't ensure that, so we reach
the check and trigger the warning. Fix the wext code to
set the ssids pointer to NULL when there are none.

------------------
From: Johannes Berg <johannes.berg@intel.com>
commit 321028bc45f01edb9e57b0ae5c11c5c3600d00ca upstream.
As noticed by syzbot, calling ieee80211_handle_queued_frames()
(and actually handling frames there) requires softirqs to be
disabled, since we call into the RX code. Fix that in the case
of cleaning up frames left over during shutdown.

The fscache_volume in cache->volumes must not have been freed yet, but its
reference count may be 0. So use the new fscache_try_get_volume() helper
function try to get its reference count.
If the reference count of fscache_volume is 0, fscache_put_volume() is
freeing it, so wait for it to be removed from cache->volumes.
If its reference count is not 0, call cachefiles_withdraw_volume() with
reference count protection to avoid the above issue.

cachefiles_daemon_release

// cachefiles_volume UAF !!!
After setting FSCACHE_CACHE_IS_WITHDRAWN, wait for all the cookie lookups
to complete first, and then wait for fscache_cache->object_count == 0 to
avoid the cookie exiting after the volume has been freed and triggering
the above issue. Therefore call fscache_withdraw_volume() before calling
cachefiles_withdraw_objects().
This way, after setting FSCACHE_CACHE_IS_WITHDRAWN, only the following two
cases will occur:
1) fscache_begin_lookup fails in fscache_begin_volume_access().
2) fscache_withdraw_volume() will ensure that fscache_count_object() has
been executed before calling fscache_wait_for_objects().
