[ Upstream commit 7c339fb4d8577792378136c15fde773cfb863cb8 ]
In ring_buffer_reset_online_cpus, the buffer_size_kb write operation
may permanently fail if the cpu_online_mask changes between two
for_each_online_buffer_cpu loops. The number of increases and decreases
on both cpu_buffer->resize_disabled and cpu_buffer->record_disabled may be
inconsistent, causing some CPUs to have non-zero values for these atomic
variables after the function returns.
This issue can be reproduced by "echo 0 > trace" while hotplugging cpu.
After reproducing success, we can find out buffer_size_kb will not be
functional anymore.
To prevent leaving 'resize_disabled' and 'record_disabled' non-zero after
ring_buffer_reset_online_cpus returns, we ensure that each atomic variable
has been set up before atomic_sub() to it.

[ Upstream commit 45121ad4a1750ca47ce3f32bd434bdb0cdbf0043 ]
The PSP IRQ is edge-triggered (MSI or MSI-X) in all cases supported by
the psp module so clear the interrupt status register early in the
handler to prevent missed interrupts. sev_irq_handler() calls wake_up()
on a wait queue, which can result in a new command being submitted from
a different CPU. This then races with the clearing of isr and can result
in missed interrupts. A missed interrupt results in a command waiting
until it times out, which results in the psp being declared dead.
This is unlikely on bare metal, but has been observed when running
virtualized. In the cases where this is observed, sev->cmdresp_reg has
PSP_CMDRESP_RESP set which indicates that the command was processed
correctly but no interrupt was asserted.
The full sequence of events looks like this:
CPU 1: submits SEV cmd #1
CPU 1: calls wait_event_timeout()
CPU 0: enters psp_irq_handler()
CPU 0: calls sev_handler()->wake_up()
CPU 1: wakes up; finishes processing cmd #1
CPU 1: submits SEV cmd #2
CPU 1: calls wait_event_timeout()
PSP: finishes processing cmd #2; interrupt status is still set; no interrupt
CPU 0: clears intsts
CPU 0: exits psp_irq_handler()
CPU 1: wait_event_timeout() times out; psp_dead=true

[ Upstream commit 3a36d20e012903f45714df2731261fdefac900cb ]
If renaming a file in an encrypted directory, function
fscrypt_setup_filename allocates memory for a file name. This name is
never used, and before returning to the caller the memory for it is not
freed.
When running kmemleak on it we see that it is registered as a leak. The
report below is triggered by a simple program 'rename' that renames a
file in an encrypted directory:
unreferenced object 0xffff888101502840 (size 32):
comm "rename", pid 9404, jiffies 4302582475 (age 435.735s)
backtrace:
__kmem_cache_alloc_node
__kmalloc
fscrypt_setup_filename
do_rename
ubifs_rename
vfs_rename
do_renameat2
To fix this we can remove the call to fscrypt_setup_filename as it's not
needed.

[ Upstream commit d469d9448a0f1a33c175d3280b1542fa0158ad7a ]
If we detect a system error via intvec, we only process the syserr if the
current ee is different than the last observed ee. The reason for this
check is to prevent bhie from running multiple times, but with the single
queue handling syserr, that is not possible.
The check can cause an issue with device recovery. If PBL loads a bad SBL
via BHI, but that SBL hangs before notifying the host of an ee change,
then issuing soc_reset to crash the device and retry (after supplying a
fixed SBL) will not recover the device as the host will observe a PBL->PBL
transition and not process the syserr. The device will be stuck until
either the driver is reloaded, or the host is rebooted. Instead, remove
the check so that we can attempt to recover the device.

[ Upstream commit 1d1493bdc25f498468a606a4ece947d155cfa3a9 ]
If firmware loading fails, the controller's pm_state is updated to
MHI_PM_FW_DL_ERR unconditionally. This can corrupt the pm_state as the
update is not done under the proper lock, and also does not validate
the state transition. The firmware loading can fail due to a detected
syserr, but if MHI_PM_FW_DL_ERR is unconditionally set as the pm_state,
the handling of the syserr can break when it attempts to transition from
syserr detect, to syserr process.
By grabbing the lock, we ensure we don't race with some other pm_state
update. By using mhi_try_set_pm_state(), we check that the transition
to MHI_PM_FW_DL_ERR is valid via the state machine logic. If it is not
valid, then some other transition is occurring like syserr processing, and
we assume that will resolve the firmware loading error.

[ Upstream commit d8a9c6e1f6766a16cf02b4e99a629f3c5512c183 ]
We allocate a structure in dpcm_be_connect(), which may be called in
atomic context. Using GFP_KERNEL is not quite right, we have to use
GFP_ATOMIC to prevent the allocator from sleeping.

[ Upstream commit bbf7d3b1c4f40eb02dd1dffb500ba00b0bff0303 ]
Since the flow for DPCM is based on taking a lock for the FE first, we
need to make sure during the connection between a BE and an FE that
they both use the same 'atomicity', otherwise we may sleep in atomic
context.
If the FE is nonatomic, this patch forces the BE to be nonatomic as
well. That should have no negative impact since the BE 'inherits' the
FE properties.
However, if the FE is atomic and the BE is not, then the configuration
is flagged as invalid.

From: Takashi Iwai <tiwai@suse.de>
[ Upstream commit b7898396f4bbe160f546d0c5e9fa17cca9a7d153 ]
The existing locking for DPCM has several issues
a) a confusing mix of card->mutex and card->pcm_mutex.
b) a dpcm_lock spinlock added inconsistently and on paths that could
be recursively taken. The use of irqsave/irqrestore was also overkill.
The suggested model is:
1) The pcm_mutex is the top-most protection of BE links in the FE. The
pcm_mutex is applied always on either the top PCM callbacks or the
external call from DAPM, not taken in the internal functions.
2) the FE stream lock is taken in higher levels before invoking
dpcm_be_dai_trigger()
3) when adding and deleting a BE, both the pcm_mutex and FE stream
lock are taken.

From: Takashi Iwai <tiwai@suse.de>
[ Upstream commit b2ae80663008a7662febe7d13f14ea1b2eb0cd51 ]
When more than one FE is connected to a BE, e.g. in a mixing use case,
the BE can be triggered multiple times when the FE are opened/started
concurrently. This race condition is problematic in the case of
SoundWire BE dailinks, and this is not desirable in a general
case.
This patch relies on the existing BE PCM lock, which takes atomicity into
account. The locking model assumes that all interactions start with
the FE, so that there is no deadlock between FE and BE locks.

On start/pause_release/resume, when more than one FE is connected to
the same BE, it's possible that the trigger is sent more than
once. This is not desirable, we only want to trigger a BE once, which
is straightforward to implement with a refcount.
For stop/pause/suspend, the problem is more complicated: the check
implemented in snd_soc_dpcm_can_be_free_stop() may fail due to a
conceptual deadlock when we trigger the BE before the FE. In this
case, the FE states have not yet changed, so there are corner cases
where the TRIGGER_STOP is never sent - the dual case of start where
multiple triggers might be sent.
This patch suggests an unconditional trigger in all cases, without
checking the FE states, using a refcount protected by the BE PCM
stream lock.

[ Upstream commit 3aa1e96a2b95e2ece198f8dd01e96818971b84df ]
A BE connected to more than one FE, e.g. in a mixer case, can go
through the following transitions.
play FE1 -> BE state is START
pause FE1 -> BE state is PAUSED
play FE2 -> BE state is START
stop FE2 -> BE state is STOP (see note [1] below)
release FE1 -> BE state is START
stop FE1 -> BE state is STOP
play FE1 -> BE state is START
pause FE1 -> BE state is PAUSED
play FE2 -> BE state is START
release FE1 -> BE state is START
stop FE2 -> BE state is START
stop FE1 -> BE state is STOP
play FE1 -> BE state is START
play FE2 -> BE state is START (no change)
pause FE1 -> BE state is START (no change)
pause FE2 -> BE state is PAUSED
release FE1 -> BE state is START
release FE2 -> BE state is START (no change)
stop FE1 -> BE state is START (no change)
stop FE2 -> BE state is STOP
The existing code for PAUSE_RELEASE only allows for the case where the
BE is paused, which clearly would not work in the sequences above.
Extend the allowed states to restart the BE when PAUSE_RELEASE is
received, and increase the refcount if the BE is already in START.
[1] the existing logic does not move the BE state back to PAUSED when
the FE2 is stopped. This patch does not change the logic; it would be
painful to keep a history of changes on the FE side, the state machine
is already rather complicated with transitions based on the last BE
state and the trigger type.

dir_search_u() # inode->i_op is set to NULL
d_splice_alias()

Existing code is causing a race condition where dirt_needed value is
already set by the host and gets overwritten with default value. Remove
this default setting of dirt_needed, to avoid overwriting the value
received in the channel callback set by vmbus_open. Removing this
setting also means the default value for dirt_needed is changed to false
as it's allocated by kzalloc which is similar to legacy hyperv_fb driver.

ncsi_channel_is_tx() determines whether a given channel should be

Clear the channel Tx enable flag before reconfiguring the channel to

[ Upstream commit da94a7781fc3c92e7df7832bc2746f4d39bc624e ]
Error handler of tcf_block_bind() frees the whole bo->cb_list on error.
However, by that time the flow_block_cb instances are already in the driver
list because driver ndo_setup_tc() callback is called before that up the
call chain in tcf_block_offload_cmd(). This leaves dangling pointers to
freed objects in the list and causes use-after-free[0]. Fix it by also
removing flow_block_cb instances from driver_list before deallocating them.

[ Upstream commit c88f8d5cd95fd039cff95d682b8e71100c001df0 ]
When a tunnel device is bound with the underlying device, its
dev->needed_headroom needs to be updated properly. IPv4 tunnels
already do the same in ip_tunnel_bind_dev(). Otherwise we may
not have enough header room for skb, especially after commit
b17f709a2401 ("gue: TX support for using remote checksum offload option").

default on a netdev basis (also on VRFs).
In an SRv6 End.DT46 behavior, decapsulated IPv4 packets are routed using
the table associated with the VRF bound to that tunnel. During lookup
operations, the rp_filter can lead to packet loss when activated on the
VRF.
Therefore, we chose to make this selftest more robust by explicitly
disabling the rp_filter during tests (as it is automatically set by some
Linux distributions).

[ Upstream commit 526f28bd0fbdc699cda31426928802650c1528e5 ]
There are cases where the device is adminstratively UP, but operationally
down. For example, we have a physical device (Nvidia ConnectX-6 Dx, 25Gbps)
who's cable was pulled out, here is its ip link output:
5: ens2f1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
link/ether b8:ce:f6:4b:68:35 brd ff:ff:ff:ff:ff:ff
altname enp179s0f1np1
As you can see, it's administratively UP but operationally down.
In this case, sending a packet to this port caused a nasty kernel hang (so
nasty that we were unable to capture it). Aborting a transmit based on
operational status (in addition to administrative status) fixes the issue.

[ Upstream commit 8ceda6d5a1e5402fd852e6cc59a286ce3dc545ee ]
The feature of flow control becomes abnormal, if the device sends a
pause frame and the tx/rx is disabled before sending a release frame. It
causes the lost of packets.
Set PLA_RX_FIFO_FULL and PLA_RX_FIFO_EMPTY to zeros before disabling the
tx/rx. And, toggle FC_PATCH_TASK before enabling tx/rx to reset the flow
control patch and timer. Then, the hardware could clear the state and
the flow control becomes normal after enabling tx/rx.
Besides, remove inline for fc_pause_on_auto() and fc_pause_off_auto().

[ Upstream commit 048486f81d01db4d100af021ee2ea211d19732a0 ]
APR table contains the lmtst base address of PF/VFs. These entries
are updated by the PF/VF during the device probe. The lmtst address
is fetched from HW using "TXN_REQ" and "ADDR_RSP_STS" registers.
The lock tries to protect these registers from getting overwritten
when multiple PFs invokes rvu_get_lmtaddr() simultaneously.
For example, if PF1 submit the request and got permitted before it
reads the response and PF2 got scheduled submit the request then the
response of PF1 is overwritten by the PF2 response.

Firmware enables PFs and allocate mbox resources for each of the PFs.
Currently PF driver configures mbox resources without checking whether
PF is enabled or not. This results in crash. This patch fixes this issue
by skipping disabled PF's mbox initialization.

hardware packet I/O is enabled. Hence disable packet I/O also
before bailing out.

From: Ido Schimmel <idosch@nvidia.com>
[ Upstream commit 9ad685dbfe7e856bbf17a7177b64676d324d6ed7 ]
It is not possible to set the number of lanes when setting link modes
using the legacy IOCTL ethtool interface. Since 'struct
ethtool_link_ksettings' is not initialized in this path, drivers receive
an uninitialized number of lanes in 'struct
ethtool_link_ksettings::lanes'.
When this information is later queried from drivers, it results in the
ethtool code making decisions based on uninitialized memory, leading to
the following KMSAN splat [1]. In practice, this most likely only
happens with the tun driver that simply returns whatever it got in the
set operation.
As far as I can tell, this uninitialized memory is not leaked to user
space thanks to the 'ethtool_ops->cap_link_lanes_supported' check in
linkmodes_prepare_data().
Fix by initializing the structure in the IOCTL path. Did not find any
more call sites that pass an uninitialized structure when calling
'ethtool_ops::set_link_ksettings()'.

we try to use devlink_priv() on the NULL return, the kernel gets very
unhappy and panics. With this fix, the driver load will still fail,
but at least it won't panic the kernel.

[ Upstream commit 6a341729fb31b4c5df9f74f24b4b1c98410c9b87 ]
syzkaller reported a warning below [0].
We can reproduce it by sending 0-byte data from the (AF_PACKET,
SOCK_PACKET) socket via some devices whose dev->hard_header_len
is 0.
struct sockaddr_pkt addr = {
.spkt_family = AF_PACKET,
.spkt_device = "tun0",
};
int fd;
fd = socket(AF_PACKET, SOCK_PACKET, 0);
sendto(fd, NULL, 0, 0, (struct sockaddr *)&addr, sizeof(addr));
We have a similar fix for the (AF_PACKET, SOCK_RAW) socket as
commit dc633700f00f ("net/af_packet: check len when min_header_len
equals to 0").
Let's add the same test for the SOCK_PACKET socket.

This patch adds a new case to handle the situation where the

[ Upstream commit 37c218d8021e36e226add4bab93d071d30fe0704 ]
The multi-chip module MT7530 switch with a 40 MHz oscillator on the
MT7621AT, MT7621DAT, and MT7621ST SoCs forwards corrupt frames using
trgmii.
This is caused by the assumption that MT7621 SoCs have got 150 MHz PLL,
hence using the ncpo1 value, 0x0780.
My testing shows this value works on Unielec U7621-06, Bartel's testing
shows it won't work on Hi-Link HLK-MT7621A and Netgear WAC104. All devices
tested have got 40 MHz oscillators.
Using the value for 125 MHz PLL, 0x0640, works on all boards at hand. The
definitions for 125 MHz PLL exist on the Banana Pi BPI-R2 BSP source code
whilst 150 MHz PLL don't.
Forwarding frames using trgmii on the MCM MT7530 switch with a 25 MHz
oscillator on the said MT7621 SoCs works fine because the ncpo1 value
defined for it is for 125 MHz PLL.
Change the 150 MHz PLL comment to 125 MHz PLL, and use the 125 MHz PLL
ncpo1 values for both oscillator frequencies.

checks the handle by mistake and might lead to unpredictable behavior.

Commit 3c22ba5243040c13 ("perf vendor events powerpc: Update POWER9
events") added and updated power9 PMU JSON events. However some of the
JSON events which are part of other.json and pipeline.json files,
contains UTF-8 characters in their brief description. Having UTF-8
character could breaks the perf build on some distros.
Fix this issue by removing the UTF-8 characters from other.json and
pipeline.json files.

From: Markus Elfring <Markus.Elfring@web.de>
[ Upstream commit c160118a90d4acf335993d8d59b02ae2147a524e ]
Addresses of two data structure members were determined before
corresponding null pointer checks in the implementation of the function
“sort__sym_from_cmp”.
Thus avoid the risk for undefined behaviour by removing extra
initialisations for the local variables “from_l” and “from_r” (also
because they were already reassigned with the same value behind this
pointer check).
This issue was detected by using the Coccinelle software.

SS_ENCRYPTION is (0 << 7 = 0), so the test can never be true.
Use a direct comparison to SS_ENCRYPTION instead.
The same king of test is already done the same way in sun8i_ss_run_task().

From: Herbert Xu <herbert@gondor.apana.org.au>
[ Upstream commit c35e03eaece71101ff6cbf776b86403860ac8cc3 ]
The crypto completion function currently takes a pointer to a
struct crypto_async_request object. However, in reality the API
does not allow the use of any part of the object apart from the
data field. For example, ahash/shash will create a fake object
on the stack to pass along a different data field.
This leads to potential bugs where the user may try to dereference
or otherwise use the crypto_async_request object.
This patch adds some temporary scaffolding so that the completion
function can take a void * instead. Once affected users have been
converted this can be removed.
The helper crypto_request_complete will remain even after the
conversion is complete. It should be used instead of calling
the completion function directly.

[ Upstream commit 4140aafcff167b5b9e8dae6a1709a6de7cac6f74 ]
CRYPTO_TFM_REQ_MAY_BACKLOG tells the crypto driver that it should
internally backlog requests until the crypto hw's queue becomes
full. At that point, crypto_engine backlogs the request and returns
-EBUSY. Calling driver such as dm-crypt then waits until the
complete() function is called with a status of -EINPROGRESS before
sending a new request.
The problem lies in the call to complete() with a value of -EINPROGRESS
that is made when a backlog item is present on the queue. The call is
done before the successful execution of the crypto request. In the case
that do_one_request() returns < 0 and the retry support is available,
the request is put back in the queue. This leads upper drivers to send
a new request even if the queue is still full.
The problem can be reproduced by doing a large dd into a crypto
dm-crypt device. This is pretty easy to see when using
Freescale CAAM crypto driver and SWIOTLB dma. Since the actual amount
of requests that can be hold in the queue is unlimited we get IOs error
and dma allocation.
The fix is to call complete with a value of -EINPROGRESS only if
the request is not enqueued back in crypto_queue. This is done
by calling complete() later in the code. In order to delay the decision,
crypto_queue is modified to correctly set the backlog pointer
when a request is enqueued back.

Previously evlist__for_each_cpu() needed to iterate over the evlist in
an inner loop and call "skip" routines. Refactor this so that the
iteratr is smarter and the next function can update both the current CPU

From: Dmitrii Dolgov <9erthalion6@gmail.com>
[ Upstream commit ecc68ee216c6c5b2f84915e1441adf436f1b019b ]
It seems that perf stat -b <prog id> doesn't produce any results:
$ perf stat -e cycles -b 4 -I 10000 -vvv
Control descriptor is not initialized
cycles: 0 0 0
time counts unit events
10.007641640 <not supported> cycles
Looks like this happens because fentry/fexit progs are getting loaded, but the
corresponding perf event is not enabled and not added into the events bpf map.
I think there is some mixing up between two type of bpf support, one for bperf
and one for bpf_profiler. Both are identified via evsel__is_bpf, based on which
perf events are enabled, but for the latter (bpf_profiler) a perf event is
required. Using evsel__is_bperf to check only bperf produces expected results:
$ perf stat -e cycles -b 4 -I 10000 -vvv
Control descriptor is not initialized
------------------------------------------------------------
perf_event_attr:
size 136
sample_type IDENTIFIER
read_format TOTAL_TIME_ENABLED|TOTAL_TIME_RUNNING
disabled 1
exclude_guest 1
------------------------------------------------------------
sys_perf_event_open: pid -1 cpu 0 group_fd -1 flags 0x8 = 3
------------------------------------------------------------
[...perf_event_attr for other CPUs...]
------------------------------------------------------------
cycles: 309426 169009 169009
time counts unit events
10.010091271 309426 cycles
The final numbers correspond (at least in the level of magnitude) to the
same metric obtained via bpftool.
Fixes: 112cb56164bc2108 ("perf stat: Introduce config stat.bpf-counter-events")

commit 6f932d4ef007d6a4ae03badcb749fbb8f49196f6 upstream.
A call to btrfs_prev_leaf() may end up returning a path that points to the
same item (key) again. This happens if while btrfs_prev_leaf(), after we
release the path, a concurrent insertion happens, which moves items off
from a sibling into the front of the previous leaf, and an item with the
computed previous key does not exists.
For example, suppose we have the two following leaves:
Leaf A
-------------------------------------------------------------
| ... key (300 96 10) key (300 96 15) key (300 96 16) |
-------------------------------------------------------------
slot 20 slot 21 slot 22
Leaf B
-------------------------------------------------------------
| key (300 96 20) key (300 96 21) key (300 96 22) ... |
-------------------------------------------------------------
slot 0 slot 1 slot 2
If we call btrfs_prev_leaf(), from btrfs_previous_item() for example, with
a path pointing to leaf B and slot 0 and the following happens:
1) At btrfs_prev_leaf() we compute the previous key to search as:
(300 96 19), which is a key that does not exists in the tree;
2) Then we call btrfs_release_path() at btrfs_prev_leaf();
3) Some other task inserts a key at leaf A, that sorts before the key at
slot 20, for example it has an objectid of 299. In order to make room
for the new key, the key at slot 22 is moved to the front of leaf B.
This happens at push_leaf_right(), called from split_leaf().
After this leaf B now looks like:
--------------------------------------------------------------------------------
| key (300 96 16) key (300 96 20) key (300 96 21) key (300 96 22) ... |
--------------------------------------------------------------------------------
slot 0 slot 1 slot 2 slot 3
4) At btrfs_prev_leaf() we call btrfs_search_slot() for the computed
previous key: (300 96 19). Since the key does not exists,
btrfs_search_slot() returns 1 and with a path pointing to leaf B
and slot 1, the item with key (300 96 20);
5) This makes btrfs_prev_leaf() return a path that points to slot 1 of
leaf B, the same key as before it was called, since the key at slot 0
of leaf B (300 96 16) is less than the computed previous key, which is
(300 96 19);
6) As a consequence btrfs_previous_item() returns a path that points again
to the item with key (300 96 20).
For some users of btrfs_prev_leaf() or btrfs_previous_item() this may not
be functional a problem, despite not making sense to return a new path
pointing again to the same item/key. However for a caller such as
tree-log.c:log_dir_items(), this has a bad consequence, as it can result
in not logging some dir index deletions in case the directory is being
logged without holding the inode's VFS lock (logging triggered while
logging a child inode for example) - for the example scenario above, in
case the dir index keys 17, 18 and 19 were deleted in the current
transaction.

find_next_bit and find_next_zero_bit take @size as the second parameter and
@offset as the third parameter. They are specified opposite in
btrfs_ensure_empty_zones(). Thanks to the later loop, it never failed to
detect the empty zones. Fix them and (maybe) return the result a bit
faster.
Note: the naming is a bit confusing, size has two meanings here, bitmap
and our range size.

commit e7db9e5c6b9615b287d01f0231904fbc1fbde9c5 upstream.
We have observed a btrfs filesystem corruption on workloads using
no-holes and encoded writes via send stream v2. The symptom is that a
file appears to be truncated to the end of its last aligned extent, even
though the final unaligned extent and even the file extent and otherwise
correctly updated inode item have been written.
So if we were writing out a 1MiB+X file via 8 128K extents and one
extent of length X, i_size would be set to 1MiB, but the ninth extent,
nbyte, etc. would all appear correct otherwise.
The source of the race is a narrow (one line of code) window in which a
no-holes fs has read in an updated i_size, but has not yet set a shared
disk_i_size variable to write. Therefore, if two ordered extents run in
parallel (par for the course for receive workloads), the following
sequence can play out: (following "threads" a bit loosely, since there
are callbacks involved for endio but extra threads aren't needed to
cause the issue)
ENC-WR1 (second to last) ENC-WR2 (last)
------- -------
btrfs_do_encoded_write
set i_size = 1M
submit bio B1 ending at 1M
endio B1
btrfs_inode_safe_disk_i_size_write
local i_size = 1M
falls off a cliff for some reason
btrfs_do_encoded_write
set i_size = 1M+X
submit bio B2 ending at 1M+X
endio B2
btrfs_inode_safe_disk_i_size_write
local i_size = 1M+X
disk_i_size = 1M+X
disk_i_size = 1M
btrfs_delayed_update_inode
btrfs_delayed_update_inode
And the delayed inode ends up filled with nbytes=1M+X and isize=1M, and
writes respect i_size and present a corrupted file missing its last
extents.
Fix this by holding the inode lock in the no-holes case so that a thread
can't sneak in a write to disk_i_size that gets overwritten with an out
of date i_size.

commit d246331b78cbef86237f9c22389205bc9b4e1cc1 upstream.
Boris noticed in his simple quotas testing that he was getting a leak
with Sweet Tea's change to subvol create that stopped doing a
transaction commit. This was just a side effect of that change.
In the delayed inode code we have an optimization that will free extra
reservations if we think we can pack a dir item into an already modified
leaf. Previously this wouldn't be triggered in the subvolume create
case because we'd commit the transaction, it was still possible but
much harder to trigger. It could actually be triggered if we did a
mkdir && subvol create with qgroups enabled.
This occurs because in btrfs_insert_delayed_dir_index(), which gets
called when we're adding the dir item, we do the following:
btrfs_block_rsv_release(fs_info, trans->block_rsv, bytes, NULL);
if we're able to skip reserving space.
The problem here is that trans->block_rsv points at the temporary block
rsv for the subvolume create, which has qgroup reservations in the block
rsv.
This is a problem because btrfs_block_rsv_release() will do the
following:
if (block_rsv->qgroup_rsv_reserved >= block_rsv->qgroup_rsv_size) {
qgroup_to_release = block_rsv->qgroup_rsv_reserved -
block_rsv->qgroup_rsv_size;
block_rsv->qgroup_rsv_reserved = block_rsv->qgroup_rsv_size;
}
The temporary block rsv just has ->qgroup_rsv_reserved set,
->qgroup_rsv_size == 0. The optimization in
btrfs_insert_delayed_dir_index() sets ->qgroup_rsv_reserved = 0. Then
later on when we call btrfs_subvolume_release_metadata() which has
btrfs_block_rsv_release(fs_info, rsv, (u64)-1, &qgroup_to_release);
btrfs_qgroup_convert_reserved_meta(root, qgroup_to_release);
qgroup_to_release is set to 0, and we do not convert the reserved
metadata space.
The problem here is that the block rsv code has been unconditionally
messing with ->qgroup_rsv_reserved, because the main place this is used
is delalloc, and any time we call btrfs_block_rsv_release() we do it
with qgroup_to_release set, and thus do the proper accounting.
The subvolume code is the only other code that uses the qgroup
reservation stuff, but it's intermingled with the above optimization,
and thus was getting its reservation freed out from underneath it and
thus leaking the reserved space.
The solution is to simply not mess with the qgroup reservations if we
don't have qgroup_to_release set. This works with the existing code as
anything that messes with the delalloc reservations always have
qgroup_to_release set. This fixes the leak that Boris was observing.

btrfs_redirty_list_add zeroes the buffer data and sets the
EXTENT_BUFFER_NO_CHECK to make sure writeback is fine with a bogus
header. But it does that after already marking the buffer dirty, which
means that writeback could already be looking at the buffer.
Switch the order of operations around so that the buffer is only marked
dirty when we're ready to write it.

commit 0004ff15ea26015a0a3a6182dca3b9d1df32e2b7 upstream.
When loading a free space cache from disk, at __load_free_space_cache(),
if we fail to insert a bitmap entry, we still increment the number of
total bitmaps in the btrfs_free_space_ctl structure, which is incorrect
since we failed to add the bitmap entry. On error we then empty the
cache by calling __btrfs_remove_free_space_cache(), which will result
in getting the total bitmaps counter set to 1.
A failure to load a free space cache is not critical, so if a failure
happens we just rebuild the cache by scanning the extent tree, which
happens at block-group.c:caching_thread(). Yet the failure will result
in having the total bitmaps of the btrfs_free_space_ctl always bigger
by 1 then the number of bitmap entries we have. So fix this by having
the total bitmaps counter be incremented only if we successfully added
the bitmap entry.
Fixes: a67509c30079 ("Btrfs: add a io_ctl struct and helpers for dealing with the space cache")

commit c915d8f5918bea7c3962b09b8884ca128bfd9b0c upstream.
When inotify_freeing_mark() races with inotify_handle_inode_event() it
can happen that inotify_handle_inode_event() sees that i_mark->wd got
already reset to -1 and reports this value to userspace which can
confuse the inotify listener. Avoid the problem by validating that wd is
sensible (and pretend the mark got removed before the event got
generated otherwise).

From: Steve French <stfrench@microsoft.com>
commit 2cb6f968775a9fd60c90a6042b9550bcec3ea087 upstream.
In investigating a failure with xfstest generic/392 it
was noticed that mounts were reusing a superblock that should
already have been freed. This turned out to be related to
deferred close files keeping a reference count until the
closetimeo expired.
Currently the only way an fs knows that mount is beginning is
when force unmount is called, but when this, ie umount_begin(),
is called all deferred close files on the share (tree
connection) should be closed immediately (unless shared by
another mount) to avoid using excess resources on the server
and to avoid reusing a superblock which should already be freed.
In umount_begin, close all deferred close handles for that
share if this is the last mount using that share on this
client (ie send the SMB3 close request over the wire for those
that have been already closed by the app but that we have
kept a handle lease open for and have not sent closes to the
server for yet).

commit 6cba655543c7959f8a6d2979b9d40a6a66b7ed4f upstream.
When CONFIG_OF_EARLY_FLATTREE and CONFIG_SH_DEVICE_TREE are not set,
SH3 build fails with a call to early_init_dt_scan(), so in
arch/sh/kernel/setup.c and arch/sh/kernel/head_32.S, use
CONFIG_OF_EARLY_FLATTREE instead of CONFIG_OF_FLATTREE.
Fixes this build error:
../arch/sh/kernel/setup.c: In function 'sh_fdt_init':
../arch/sh/kernel/setup.c:262:26: error: implicit declaration of function 'early_init_dt_scan' [-Werror=implicit-function-declaration]

commit d1155e4132de712a9d3066e2667ceaad39a539c5 upstream.
__setup() handlers should return 1 to obsolete_checksetup() in
init/main.c to indicate that the boot option has been handled.
A return of 0 causes the boot option/value to be listed as an Unknown
kernel parameter and added to init's (limited) argument or environment
strings. Also, error return codes don't mean anything to
obsolete_checksetup() -- only non-zero (usually 1) or zero.
So return 1 from nmi_debug_setup().

commit 665b9459bb53b8f19bd1541567e1fe9782c83c4b upstream.
The Samsung S5P/Exynos MIPI CSIS bindings and Linux driver expect first
clock name to be "csis". Otherwise the driver fails to probe.

This is the logical place to put the backlight device, and it also
fixes a kernel crash if the MIPI host is removed. Previously the
backlight device would be unregistered twice when this happened - once
as a child of the MIPI host through `mipi_dsi_host_unregister`, and
once when the panel device is destroyed.

commit 08da182175db4c7f80850354849d95f2670e8cd9 upstream.
Currently, on a handful of ASICs. We allow the framebuffer for a given
plane to exist in either VRAM or GTT. However, if the plane's new
framebuffer is in a different memory domain than it's previous
framebuffer, flipping between them can cause the screen to flicker. So,
to fix this, don't perform an immediate flip in the aforementioned case.

v1: Vmbo->shadow is used to back vram bo up when vram lost. So that we
should set shadow as vmbo->shadow to recover vmbo->bo
v2: Modify if(vmbo->shadow) shadow = vmbo->shadow as if(!vmbo->shadow)

commit 8b229ada2669b74fdae06c83fbfda5a5a99fc253 upstream.
sdma_v4_0_ip is shared on a few asics, but in sdma_v4_0_hw_fini,
driver unconditionally disables ecc_irq which is only enabled on
those asics enabling sdma ecc. This will introduce a warning in
suspend cycle on those chips with sdma ip v4.0, while without
sdma ecc. So this patch correct this.

From: Ping Cheng <pinglinux@gmail.com>
commit 17d793f3ed53080dab6bbeabfc82de890c901001 upstream.
To fully utilize the BT polling/refresh rate, a few input events
are sent together to reduce event delay. This causes issue to the
timestamp generated by input_sync since all the events in the same
packet would pretty much have the same timestamp. This patch inserts
time interval to the events by averaging the total time used for
sending the packet.
This decision was mainly based on observing the actual time interval
between each BT polling. The interval doesn't seem to be constant,
due to the network and system environment. So, using solutions other
than averaging doesn't end up with valid timestamps.

commit 3c75c0ea5da749bd1efebd1387f2e5011b8c7d78 upstream.
The recent change for DPCM locking caused spurious lockdep warnings.
Actually the warnings are false-positive, as those are triggered due
to the nested stream locks for FE and BE. Since both locks belong to
the same lock class, lockdep sees it as if a deadlock.
For fixing this, we need to take PCM stream locks for BE with the
nested lock primitives. Since currently snd_pcm_stream_lock*() helper
assumes only the top-level single locking, a new helper function
snd_pcm_stream_lock_irqsave_nested() is defined for a single-depth
nested lock, which is now used in the BE DAI trigger that is always
performed inside a FE stream lock.
Fixes: b2ae80663008 ("ASoC: soc-pcm: serialize BE triggers")

commit 37b58becc1cee4d591024f2056d7ffa99c6089e0 upstream.
After commit bbf7d3b1c4f40 ("ASoC: soc-pcm: align BE 'atomicity' with
that of the FE") BE and FE atomicity must match.
In the case of Compress PCM there is a mismatch in atomicity between FE
and BE and we get errors like this:
[ 36.434566] sai1-wm8960-hifi: dpcm_be_connect: FE is atomic but BE
is nonatomic, invalid configuration
[ 36.444278] PCM Deep Buffer: ASoC: can't connect SAI1.OUT
In order to fix this we must inherit the atomicity from DAI link
associated with current PCM Compress FE.

commit 9f620684c1ef5a002b6622ecc7b5818e81252f48 upstream.
The recent fix for DPCM locking also covered the loop in
dpcm_be_disconnect() with the FE stream lock. This caused an
unexpected side effect, thought: calling debugfs_remove_recursive() in
the spinlock may lead to lockdep splats as the code there assumes the
SOFTIRQ-safe context.
For avoiding the problem, this patch changes the disconnection
procedure to two phases: at first, the matching entries are removed
from the linked list, then the resources are freed outside the lock.

From: Takashi Iwai <tiwai@suse.de>
commit 754590651ccbbcc74a7c20907be4bb15d642bde3 upstream.
When DPCM tries to add valid BE connections at dpcm_add_paths(), it
doesn't check whether the picked BE actually supports for the given
stream direction. Due to that, when an asymmetric BE stream is
present, it picks up wrongly and this may result in a NULL dereference
at a later point where the code assumes the existence of a
corresponding BE substream.
This patch adds the check for the presence of the substream for the
target BE for avoiding the problem above.
Note that we have already some fix for non-existing BE substream at
commit 6246f283d5e0 ("ASoC: dpcm: skip missing substream while
applying symmetry"). But the code path we've hit recently is rather
happening before the previous fix. So this patch tries to fix at
picking up a BE instead of parsing BE lists.

[ Upstream commit c28e2f2b417ed747bfbc5f900c87f3ec9cc6b25e ]
The remaining struct_mutex usage is just to serialize various gpu
related things (submit/retire/recover/fault/etc), so replace
struct_mutex with gpu->lock.

[ Upstream commit 0d997f95b70f98987ae031a89677c13e0e223670 ]
A recent commit moved enabling of runtime PM to GPU load time (first
open()) but failed to update the error paths so that runtime PM is
disabled if initialisation of the GPU fails. This would trigger a
warning about the unbalanced disable count on the next open() attempt.
Note that pm_runtime_put_noidle() is sufficient to balance the usage
count when pm_runtime_put_sync() fails (and is chosen over
pm_runtime_resume_and_get() for consistency reasons).

[ Upstream commit 63f8bee439c0e3f94cff90d0f9c7b719be693265 ]
[Why]
In some scenarios like fullscreen game, major plane is scaled. Then
if a upper layer owns the cursor, cursor is invisiable in the
majority of the screen.
[How]
Instead assuming upper plane handles cursor, summing up upper
split planes on the same layer. If whole upper plane covers current
half/whole pipe plane, disable cursor.

[ Upstream commit d29fb7baab09b6a1dc484c9c67933253883e770a ]
[Why]
While scanning the top_pipe connections we can run into a case where
the bottom pipe is still connected to a top_pipe but with a NULL
plane_state.
[How]
Treat a NULL plane_state the same as the plane being invisible for
pipe cursor disable logic.

[ Upstream commit 14705f969d98187a1cc2682e0c9bd2e230b8098f ]
On my RTW8821CU chipset rfe_option reads as 0x22. Looking at the
vendor driver suggests that the field width of rfe_option is 5 bit,
so rfe_option should be masked with 0x1f.
Without this the rfe_option comparisons with 2 further down the
driver evaluate as false when they should really evaluate as true.
The effect is that 2G channels do not work.
rfe_option is also used as an array index into rtw8821c_rfe_defs[].
rtw8821c_rfe_defs[34] (0x22) was added as part of adding USB support,
likely because rfe_option reads as 0x22. As this now becomes 0x2,
rtw8821c_rfe_defs[34] is no longer used and can be removed.
Note that this might not be the whole truth. In the vendor driver
there are indeed places where the unmasked rfe_option value is used.
However, the driver has several places where rfe_option is tested
with the pattern if (rfe_option == 2 || rfe_option == 0x22) or
if (rfe_option == 4 || rfe_option == 0x24), so that rfe_option BIT(5)
has no influence on the code path taken. We therefore mask BIT(5)
out from rfe_option entirely until this assumption is proved wrong
by some chip variant we do not know yet.

[ Upstream commit ce53d365378cde71bb6596d79c257e600d951d29 ]
When RSS mode is enable, windows client do simultaneously send several
session requests to server. There is racy issue using
sess->ntlmssp.cryptkey on N connection : 1 session. So authetication
failed using wrong cryptkey on some session. This patch move cryptkey
to ksmbd_conn structure to use each cryptkey on connection.

[ Upstream commit 17ea92a9f6d0b9a97aaec5ab748e4591d70a562c ]
There is a report that kernel oops happen from idr_remove().

kernel: kthread+0xee/0x120
kthread_complete_and_exit+0x20/0x20
kernel: ret_from_fork+0x22/0x30
While accessing files, If connection is disconnected, windows send
session setup request included previous session destroy. But while still
processing requests on previous session, this request destroy file
table, which mean file table idr will be freed and set to NULL.
So kernel oops happen from ft->idr in __ksmbd_close_fd().
This patch don't directly destroy session in destroy_previous_session().
It just set to KSMBD_SESS_EXITING so that connection will be
terminated after finishing the rest of requests.

[ Upstream commit af7c39d971e43cd0af488729bca362427ad99488 ]
After multi-channel connection with windows, Several channels of
session are connected. Among them, if there is a problem in one channel,
Windows connects again after disconnecting the channel. In this process,
the session is released and a kernel oop can occurs while processing
requests to other channels. When the channel is disconnected, if other
channels still exist in the session after deleting the channel from
the channel list in the session, the session should not be released.
Finally, the session will be released after all channels are disconnected.

[ Upstream commit 7b4323373d844954bb76e0e9f39c4e5fc785fa7b ]
Deadlock is triggered by sending multiple concurrent session setup
requests. It should be reused after releasing when getting ctx for crypto.
Multiple consecutive ctx uses cause deadlock while waiting for releasing
due to the limited number of ctx.

From: John Stultz <jstultz@google.com>
commit 92cc5d00a431e96e5a49c0b97e5ad4fa7536bd4b upstream.
Apparently despite it being marked inline, the compiler
may not inline __down_read_common() which makes it difficult
to identify the cause of lock contention, as the blocked
function in traceevents will always be listed as
__down_read_common().
So this patch adds __always_inline annotation to the common
function (as well as the inlined helper callers) to force it to
be inlined so the blocking function will be listed (via Wchan)
in traceevents.
Fixes: c995e638ccbb ("locking/rwsem: Fold __down_{read,write}*()")

Acctually, blocks per group is 64, but block bitmap indicate at least has
128 blocks. Now, ext4_validate_block_bitmap() didn't check invalid block's
bitmap if set.
To resolve above issue, add check like fsck "Padding at end of block bitmap is
not set".

Replace
le16_to_cpu(sbi->s_es->s_desc_size)
with
sbi->s_desc_size
It reduces ext4's compiled text size, and makes the code more efficient
(we remove an extra indirect reference and a potential byte
swap on big endian systems), and there is no downside. It also avoids the
potential KASAN / syzkaller failure, as a bonus.

commit 492888df0c7b42fc0843631168b0021bc4caee84 upstream.
When using cached extent stored in extent status tree in tree->cache_es
another process holding ei->i_es_lock for reading can be racing with us
setting new value of tree->cache_es. If the compiler would decide to
refetch tree->cache_es at an unfortunate moment, it could result in a
bogus in_range() check. Fix the possible race by using READ_ONCE() when
using tree->cache_es only under ei->i_es_lock for reading.

From: Baokun Li <libaokun1@huawei.com>
commit fa83c34e3e56b3c672af38059e066242655271b1 upstream.
When ext4_iomap_overwrite_begin() calls ext4_iomap_begin() map blocks may
fail for some reason (e.g. memory allocation failure, bare disk write), and
later because "iomap->type ! = IOMAP_MAPPED" triggers WARN_ON(). When ext4
iomap_begin() returns an error, it is normal that the type of iomap->type
may not match the expectation. Therefore, we only determine if iomap->type
is as expected when ext4_iomap_begin() is executed successfully.

commit 4c0b4818b1f636bc96359f7817a2d8bab6370162 upstream.
If there are failures while changing the mount options in
__ext4_remount(), we need to restore the old mount options.
This commit fixes two problem. The first is there is a chance that we
will free the old quota file names before a potential failure leading
to a use-after-free. The second problem addressed in this commit is
if there is a failed read/write to read-only transition, if the quota
has already been suspended, we need to renable quota handling.

commit 4b3cb1d108bfc2aebb0d7c8a52261a53cf7f5786 upstream.
The ext4_dirhash() will *almost* never fail, especially when the hash
tree feature was first introduced. However, with the addition of
support of encrypted, casefolded file names, that function can most
certainly fail today.
So make sure the callers of ext4_dirhash() properly check for
failures, and reflect the errors back up to their callers.

From: Theodore Ts'o <tytso@mit.edu>
commit f4ce24f54d9cca4f09a395f3eecce20d6bec4663 upstream.
In no journal mode, ext4_finish_convert_inline_dir() can self-deadlock
by calling ext4_handle_dirty_dirblock() when it already has taken the
directory lock. There is a similar self-deadlock in
ext4_incvert_inline_data_nolock() for data files which we'll fix at
the same time.
A simple reproducer demonstrating the problem:
mke2fs -Fq -t ext2 -O inline_data -b 4k /dev/vdc 64
mount -t ext4 -o dirsync /dev/vdc /vdc
cd /vdc
mkdir file0
cd file0
touch file0
touch file1
attr -s BurnSpaceInEA -V abcde .
touch supercalifragilisticexpialidocious

commit 2220eaf90992c11d888fe771055d4de330385f01 upstream.
Normally the extended attributes in the inode body would have been
checked when the inode is first opened, but if someone is writing to
the block device while the file system is mounted, it's possible for
the inode table to get corrupted. Add bounds checking to avoid
reading beyond the end of allocated memory if this happens.

If a malicious fuzzer overwrites the ext4 superblock while it is
mounted such that the s_first_data_block is set to a very large
number, the calculation of the block group can underflow, and trigger
a BUG_ON check. Change this to be an ext4_warning so that we don't
crash the kernel.

From: Theodore Ts'o <tytso@mit.edu>
commit b87c7cdf2bed4928b899e1ce91ef0d147017ba45 upstream.
In ext4_xattr_move_to_block(), the value of the extended attribute
which we need to move to an external block may be allocated by
kvmalloc() if the value is stored in an external inode. So at the end
of the function the code tried to check if this was the case by
testing entry->e_value_inum.
However, at this point, the pointer to the xattr entry is no longer
valid, because it was removed from the original location where it had
been stored. So we could end up calling kvfree() on a pointer which
was not allocated by kvmalloc(); or we could also potentially leak
memory by not freeing the buffer when it should be freed. Fix this by
storing whether it should be freed in a separate variable.

commit 3eeca5e5f3100435b06a5b5d86daa3d135a8a4bd upstream.
The adreno_load_gpu() path is guarded by an error check on
adreno_load_fw(). This function is responsible for loading
Qualcomm-only-signed binaries (e.g. SQE and GMU FW for A6XX), but it
does not take the vendor-signed ZAP blob into account.
By embedding the SQE (and GMU, if necessary) firmware into the
initrd/kernel, we can trigger and unfortunate path that would not bail
out early and proceed with gpu->hw_init(). That will fail, as the ZAP
loader path will not find the firmware and return back to
adreno_load_gpu().
This error path involves pm_runtime_put_sync() which then calls idle()
instead of suspend(). This is suboptimal, as it means that we're not
going through the clean shutdown sequence. With at least A619_holi, this
makes the GPU not wake up until it goes through at least one more
start-fail-stop cycle. The pm_runtime_put_sync that appears in the error
path actually does not guarantee that because of the earlier enabling of
runtime autosuspend.
Fix that by using pm_runtime_put_sync_suspend to force a clean shutdown.
Test cases:
1. All firmware baked into kernel
2. error loading ZAP fw in initrd -> load from rootfs at DE start
Both succeed on A619_holi (SM6375) and A630 (SDM845).

From: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com>
commit 146a37e05d620cef4ad430e5d1c9c077fe6fa76f upstream.
There's a potential race before THRE/TEMT deasserts when DMA Tx is
starting up (or the next batch of continuous Tx is being submitted).
This can lead to misdetecting Tx empty condition.
It is entirely normal for THRE/TEMT to be set for some time after the
DMA Tx had been setup in serial8250_tx_dma(). As Tx side is definitely
not empty at that point, it seems incorrect for serial8250_tx_empty()
claim Tx is empty.
Fix the race by also checking in serial8250_tx_empty() whether there's
DMA Tx active.
Note: This fix only addresses in-kernel race mainly to make using
TCSADRAIN/FLUSH robust. Userspace can still cause other races but they
seem userspace concurrency control problems.

commit 3899d94e3831ee07ea6821c032dc297aec80586a upstream.
When we receive a flush command (or "barrier" in DRBD), we currently use
a REQ_OP_FLUSH with the REQ_PREFLUSH flag set.
The correct way to submit a flush bio is by using a REQ_OP_WRITE without
any data, and set the REQ_PREFLUSH flag.
Since commit b4a6bb3a67aa ("block: add a sanity check for non-write
flush/fua bios"), this triggers a warning in the block layer, but this
has been broken for quite some time before that.
So use the correct set of flags to actually make the flush happen.
