[PATCH AUTOSEL 6.1 01/48] drm/vc4: hdmi: Avoid log spam for audio start failure

[PATCH AUTOSEL 6.1 01/48] drm/vc4: hdmi: Avoid log spam for audio start failure

[Sasha Levin]

From: Dom Cobley <popcornmix@gmail.com>

[ Upstream commit b4e5646178e86665f5caef2894578600f597098a ]

We regularly get dmesg error reports of:
[   18.184066] hdmi-audio-codec hdmi-audio-codec.3.auto: ASoC: error at snd_soc_dai_startup on i2s-hifi: -19
[   18.184098]  MAI: soc_pcm_open() failed (-19)

These are generated for any disconnected hdmi interface when pulseaudio
attempts to open the associated ALSA device (numerous times). Each open
generates a kernel error message, generating general log spam.

The error messages all come from _soc_pcm_ret in sound/soc/soc-pcm.c#L39
which suggests returning ENOTSUPP, rather that ENODEV will be quiet.
And indeed it is.

[PATCH AUTOSEL 6.1 02/48] drm/vc4: hvs: Set AXI panic modes for the HVS

[Sasha Levin]

From: Dave Stevenson <dave.stevenson@raspberrypi.com>

[ Upstream commit 014eccc9da7bfc76a3107fceea37dd60f1d63630 ]

The HVS can change AXI request mode based on how full the COB
FIFOs are.
Until now the vc4 driver has been relying on the firmware to
have set these to sensible values.

With HVS channel 2 now being used for live video, change the
panic mode for all channels to be explicitly set by the driver,
and the same for all channels.

[PATCH AUTOSEL 6.1 03/48] drm: panel-orientation-quirks: Add quirk for AYA NEO 2 model

From: Joaquín Ignacio Aramendía <samsagax@gmail.com>

[ Upstream commit 361ebf5ef843b0aa1704c72eb26b91cf76c3c5b7 ]

Add quirk orientation for AYA NEO 2. The name appears without spaces in
DMI strings. That made it difficult to reuse the 2021 match. Also the
display is larger in resolution.

Tested by the JELOS team that has been patching their own kernel for a
while now and confirmed by users in the AYA NEO and ChimeraOS discord
servers.

From: Joaquín Ignacio Aramendía <samsagax@gmail.com>

[ Upstream commit d7972d735ca80a40a571bf753c138263981a5698 ]

Add quirk orientation for AYA NEO Founder. The name appears with spaces in

[ Upstream commit a1e2da6a5072f8abe5b0feaa91a5bcd9dc544a04 ]

It is possible, although unlikely, that an integer overflow will occur
when the result of radeon_get_ib_value() is shifted to the left.

Avoid it by casting one of the operands to larger data type (u64).

[PATCH AUTOSEL 6.1 09/48] drm/display: Fix building with GCC 15

[Sasha Levin]

From: Brahmajit Das <brahmajit.xyz@gmail.com>

[ Upstream commit a500f3751d3c861be7e4463c933cf467240cca5d ]

GCC 15 enables -Werror=unterminated-string-initialization by default.
This results in the following build error

drivers/gpu/drm/display/drm_dp_dual_mode_helper.c: In function ‘is_hdmi_adaptor’:
drivers/gpu/drm/display/drm_dp_dual_mode_helper.c:164:17: error: initializer-string for array of
 ‘char’ is too long [-Werror=unterminated-string-initialization]
  164 |                 "DP-HDMI ADAPTOR\x04";
      |                 ^~~~~~~~~~~~~~~~~~~~~

After discussion with Ville, the fix was to increase the size of
dp_dual_mode_hdmi_id array by one, so that it can accommodate the NULL
line character. This should let us build the kernel with GCC 15.

[PATCH AUTOSEL 6.1 14/48] net/sched: cbs: Fix integer overflow in cbs_set_port_rate()

[Sasha Levin]

From: Elena Salomatkina <esalomatkina@ispras.ru>

[ Upstream commit 397006ba5d918f9b74e734867e8fddbc36dc2282 ]

The subsequent calculation of port_rate = speed * 1000 * BYTES_PER_KBIT,
where the BYTES_PER_KBIT is of type LL, may cause an overflow.
At least when speed = SPEED_20000, the expression to the left of port_rate
will be greater than INT_MAX.

[PATCH AUTOSEL 6.1 15/48] af_packet: avoid erroring out after sock_init_data() in packet_create()

From: Ignat Korchagin <ignat@cloudflare.com>

[ Upstream commit 46f2a11cb82b657fd15bab1c47821b635e03838b ]

After sock_init_data() the allocated sk object is attached to the provided
sock object. On error, packet_create() frees the sk object leaving the
dangling pointer in the sock object on return. Some other code may try
to use this pointer and cause use-after-free.

[PATCH AUTOSEL 6.1 26/48] drm/sched: memset() 'job' in drm_sched_job_init()

[Sasha Levin]

From: Philipp Stanner <pstanner@redhat.com>

[ Upstream commit 2320c9e6a768d135c7b0039995182bb1a4e4fd22 ]

drm_sched_job_init() has no control over how users allocate struct
drm_sched_job. Unfortunately, the function can also not set some struct
members such as job->sched.

This could theoretically lead to UB by users dereferencing the struct's
pointer members too early.

It is easier to debug such issues if these pointers are initialized to
NULL, so dereferencing them causes a NULL pointer exception.
Accordingly, drm_sched_entity_init() does precisely that and initializes
its struct with memset().

Initialize parameter "job" to 0 in drm_sched_job_init().

[PATCH AUTOSEL 6.1 27/48] drm/amdgpu: clear RB_OVERFLOW bit when enabling interrupts for vega20_ih

[Sasha Levin]

From: Victor Lu <victorchengchi.lu@amd.com>

[ Upstream commit 8b22f048331dfd45fdfbf0efdfb1d43deff7518d ]

Port this change to vega20_ih.c:
commit afbf7955ff01 ("drm/amdgpu: clear RB_OVERFLOW bit when enabling interrupts")

Original commit message:
"Why:
Setting IH_RB_WPTR register to 0 will not clear the RB_OVERFLOW bit
if RB_ENABLE is not set.

How to fix:
Set WPTR_OVERFLOW_CLEAR bit after RB_ENABLE bit is set.
The RB_ENABLE bit is required to be set, together with
WPTR_OVERFLOW_ENABLE bit so that setting WPTR_OVERFLOW_CLEAR bit
would clear the RB_OVERFLOW."

[PATCH AUTOSEL 6.1 30/48] dma-debug: fix a possible deadlock on radix_lock

[Sasha Levin]

From: Levi Yun <yeoreum.yun@arm.com>

[ Upstream commit 7543c3e3b9b88212fcd0aaf5cab5588797bdc7de ]

radix_lock() shouldn't be held while holding dma_hash_entry[idx].lock
otherwise, there's a possible deadlock scenario when
dma debug API is called holding rq_lock():

CPU0                   CPU1                       CPU2
dma_free_attrs()
check_unmap()          add_dma_entry()            __schedule() //out
                                                  (A) rq_lock()
get_hash_bucket()
(A) dma_entry_hash
                                                  check_sync()
                       (A) radix_lock()           (W) dma_entry_hash
dma_entry_free()
(W) radix_lock()
                       // CPU2's one
                       (W) rq_lock()

CPU1 situation can happen when it extending radix tree and
it tries to wake up kswapd via wake_all_kswapd().

CPU2 situation can happen while perf_event_task_sched_out()
(i.e. dma sync operation is called while deleting perf_event using
 etm and etr tmc which are Arm Coresight hwtracing driver backends).

To remove this possible situation, call dma_entry_free() after
put_hash_bucket() in check_unmap().

[PATCH AUTOSEL 6.1 33/48] jfs: fix array-index-out-of-bounds in jfs_readdir

[Sasha Levin]

From: Ghanshyam Agrawal <ghanshyam1898@gmail.com>

[ Upstream commit 839f102efb168f02dfdd46717b7c6dddb26b015e ]

The stbl might contain some invalid values. Added a check to
return error code in that case.

[PATCH AUTOSEL 6.1 34/48] jfs: add a check to prevent array-index-out-of-bounds in dbAdjTree

[Sasha Levin]

From: Nihar Chaithanya <niharchaithanya@gmail.com>

[ Upstream commit a174706ba4dad895c40b1d2277bade16dfacdcd9 ]

When the value of lp is 0 at the beginning of the for loop, it will
become negative in the next assignment and we should bail out.

[PATCH AUTOSEL 6.1 35/48] net: enetc: remove ERR050089 workaround for i.MX95

[Sasha Levin]

From: Vladimir Oltean <vladimir.oltean@nxp.com>

[ Upstream commit 86831a3f4cd4c924dd78cf0d6e4d73acacfe1b11 ]

The ERR050089 workaround causes performance degradation and potential
functional issues (e.g., RCU stalls) under certain workloads. Since
new SoCs like i.MX95 do not require this workaround, use a static key
to compile out enetc_lock_mdio() and enetc_unlock_mdio() at runtime,
improving performance and avoiding unnecessary logic.

[PATCH AUTOSEL 6.1 36/48] net: enetc: add i.MX95 EMDIO support

[Sasha Levin]

From: Wei Fang <wei.fang@nxp.com>

[ Upstream commit a52201fb9caa9b33b4d881725d1ec733438b07f2 ]

The verdor ID and device ID of i.MX95 EMDIO are different from LS1028A
EMDIO, so add new vendor ID and device ID to pci_device_id table to
support i.MX95 EMDIO.

[PATCH AUTOSEL 6.1 37/48] drm/amdgpu: skip amdgpu_device_cache_pci_state under sriov

[Sasha Levin]

From: Victor Zhao <Victor.Zhao@amd.com>

[ Upstream commit afe260df55ac280cd56306248cb6d8a6b0db095c ]

Under sriov, host driver will save and restore vf pci cfg space during
reset. And during device init, under sriov, pci_restore_state happens after
fullaccess released, and it can have race condition with mmio protection
enable from host side leading to missing interrupts.

So skip amdgpu_device_cache_pci_state for sriov.

[PATCH AUTOSEL 6.1 38/48] ALSA: usb-audio: Make mic volume workarounds globally applicable

[Sasha Levin]

From: Takashi Iwai <tiwai@suse.de>

[ Upstream commit d6e6b9218ced5249b9136833ef5ec3f554ec7fde ]

It seems that many webcams have buggy firmware and don't expose the
mic capture volume with the proper resolution.  We have workarounds in
mixer.c, but judging from the numbers, those can be better managed as
global quirk flags.

[PATCH AUTOSEL 6.1 39/48] drm/amdgpu: set the right AMDGPU sg segment limitation

[Sasha Levin]

From: Prike Liang <Prike.Liang@amd.com>

[ Upstream commit e2e97435783979124ba92d6870415c57ecfef6a5 ]

The driver needs to set the correct max_segment_size;
otherwise debug_dma_map_sg() will complain about the
over-mapping of the AMDGPU sg length as following:

[PATCH AUTOSEL 6.1 41/48] wifi: brcmfmac: Fix oops due to NULL pointer dereference in brcmf_sdiod_sglist_rw()

[Sasha Levin]

From: Norbert van Bolhuis <nvbolhuis@gmail.com>

[ Upstream commit 857282b819cbaa0675aaab1e7542e2c0579f52d7 ]

This patch fixes a NULL pointer dereference bug in brcmfmac that occurs
when a high 'sd_sgentry_align' value applies (e.g. 512) and a lot of queued SKBs
are sent from the pkt queue.

The problem is the number of entries in the pre-allocated sgtable, it is
nents = max(rxglom_size, txglom_size) + max(rxglom_size, txglom_size) >> 4 + 1.
Given the default [rt]xglom_size=32 it's actually 35 which is too small.
Worst case, the pkt queue can end up with 64 SKBs. This occurs when a new SKB
is added for each original SKB if tailroom isn't enough to hold tail_pad.
At least one sg entry is needed for each SKB. So, eventually the "skb_queue_walk loop"
in brcmf_sdiod_sglist_rw may run out of sg entries. This makes sg_next return
NULL and this causes the oops.

The patch sets nents to max(rxglom_size, txglom_size) * 2 to be able handle
the worst-case.
Btw. this requires only 64-35=29 * 16 (or 20 if CONFIG_NEED_SG_DMA_LENGTH) = 464
additional bytes of memory.

[PATCH AUTOSEL 6.1 42/48] dsa: qca8k: Use nested lock to avoid splat

[Sasha Levin]

From: Andrew Lunn <andrew@lunn.ch>

[ Upstream commit 078e0d596f7b5952dad8662ace8f20ed2165e2ce ]

qca8k_phy_eth_command() is used to probe the child MDIO bus while the
parent MDIO is locked. This causes lockdep splat, reporting a possible
deadlock. It is not an actually deadlock, because different locks are
used. By making use of mutex_lock_nested() we can avoid this false
positive.

[PATCH AUTOSEL 6.1 44/48] Bluetooth: hci_core: Fix not checking skb length on hci_acldata_packet

[Sasha Levin]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

[ Upstream commit 3fe288a8214e7dd784d1f9b7c9e448244d316b47 ]

This fixes not checking if skb really contains an ACL header otherwise
the code may attempt to access some uninitilized/invalid memory past the
valid skb->data.

[PATCH AUTOSEL 6.1 45/48] ASoC: hdmi-codec: reorder channel allocation list

[Sasha Levin]

From: Jonas Karlman <jonas@kwiboo.se>

[ Upstream commit 82ff5abc2edcfba0c0f1a1be807795e2876f46e9 ]

The ordering in hdmi_codec_get_ch_alloc_table_idx() results in
wrong channel allocation for a number of cases, e.g. when ELD
reports FL|FR|LFE|FC|RL|RR or FL|FR|LFE|FC|RL|RR|RC|RLC|RRC:

ca_id 0x01 with speaker mask FL|FR|LFE is selected instead of
ca_id 0x03 with speaker mask FL|FR|LFE|FC for 4 channels

and

ca_id 0x04 with speaker mask FL|FR|RC gets selected instead of
ca_id 0x0b with speaker mask FL|FR|LFE|FC|RL|RR for 6 channels

Fix this by reordering the channel allocation list with most
specific speaker masks at the top.

[PATCH AUTOSEL 6.1 46/48] rocker: fix link status detection in rocker_carrier_init()

[Sasha Levin]

From: Dmitry Antipov <dmantipov@yandex.ru>

[ Upstream commit e64285ff41bb7a934bd815bd38f31119be62ac37 ]

Since '1 << rocker_port->pport' may be undefined for port >= 32,
cast the left operand to 'unsigned long long' like it's done in
'rocker_port_set_enable()' above. Compile tested only.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

[PATCH AUTOSEL 6.1 47/48] net/neighbor: clear error in case strict check is not set

[Sasha Levin]

From: Jakub Kicinski <kuba@kernel.org>

[ Upstream commit 0de6a472c3b38432b2f184bd64eb70d9ea36d107 ]

Commit 51183d233b5a ("net/neighbor: Update neigh_dump_info for strict
data checking") added strict checking. The err variable is not cleared,
so if we find no table to dump we will return the validation error even
if user did not want strict checking.

I think the only way to hit this is to send an buggy request, and ask
for a table which doesn't exist, so there's no point treating this
as a real fix. I only noticed it because a syzbot repro depended on it
to trigger another bug.

[PATCH AUTOSEL 6.1 48/48] netpoll: Use rcu_access_pointer() in __netpoll_setup

[Sasha Levin]

From: Breno Leitao <leitao@debian.org>

[ Upstream commit c69c5e10adb903ae2438d4f9c16eccf43d1fcbc1 ]

The ndev->npinfo pointer in __netpoll_setup() is RCU-protected but is being
accessed directly for a NULL check. While no RCU read lock is held in this
context, we should still use proper RCU primitives for consistency and
correctness.

Replace the direct NULL check with rcu_access_pointer(), which is the
appropriate primitive when only checking for NULL without dereferencing
the pointer. This function provides the necessary ordering guarantees
without requiring RCU read-side protection.

Hi Sasha,

This patch does not need to be backported, because i.MX95 NETC is only
supported in the latest kernel (should be 6.13, Linus tree). For the old
kernel, only LS1028A NETC is supported, so this problem does not exist.
