[PATCH AUTOSEL 6.12 02/29] wifi: mac80211: fix mbss changed flags corruption on 32 bit systems

[Sasha Levin]

From: Issam Hamdi <ih@simonwunderlich.de>

[ Upstream commit 49dba1ded8dd5a6a12748631403240b2ab245c34 ]

On 32-bit systems, the size of an unsigned long is 4 bytes,
while a u64 is 8 bytes. Therefore, when using
or_each_set_bit(bit, &bits, sizeof(changed) * BITS_PER_BYTE),
the code is incorrectly searching for a bit in a 32-bit
variable that is expected to be 64 bits in size,
leading to incorrect bit finding.

Solution: Ensure that the size of the bits variable is correctly
adjusted for each architecture.

[PATCH AUTOSEL 6.12 03/29] wifi: cfg80211: clear link ID from bitmap during link delete after clean up

[Sasha Levin]

From: Aditya Kumar Singh <quic_adisi@quicinc.com>

[ Upstream commit b5c32ff6a3a38c74facdd1fe34c0d709a55527fd ]

Currently, during link deletion, the link ID is first removed from the
valid_links bitmap before performing any clean-up operations. However, some
functions require the link ID to remain in the valid_links bitmap. One
such example is cfg80211_cac_event(). The flow is -

nl80211_remove_link()
    cfg80211_remove_link()
        ieee80211_del_intf_link()
            ieee80211_vif_set_links()
                ieee80211_vif_update_links()
                    ieee80211_link_stop()
                        cfg80211_cac_event()

cfg80211_cac_event() requires link ID to be present but it is cleared
already in cfg80211_remove_link(). Ultimately, WARN_ON() is hit.

Therefore, clear the link ID from the bitmap only after completing the link
clean-up.

[PATCH AUTOSEL 6.12 04/29] wifi: mac80211: wake the queues in case of failure in resume

[Sasha Levin]

From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

[ Upstream commit 220bf000530f9b1114fa2a1022a871c7ce8a0b38 ]

In case we fail to resume, we'll WARN with
"Hardware became unavailable during restart." and we'll wait until user
space does something. It'll typically bring the interface down and up to
recover. This won't work though because the queues are still stopped on
IEEE80211_QUEUE_STOP_REASON_SUSPEND reason.
Make sure we clear that reason so that we give a chance to the recovery
to succeed.

[PATCH AUTOSEL 6.12 06/29] drm/amdkfd: Correct the migration DMA map direction

[Sasha Levin]

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

[ Upstream commit 5c3de6b02d38eb9386edf50490e050bb44398e40 ]

The SVM DMA device map direction should be set the same as
the DMA unmap setting, otherwise the DMA core will report
the following warning.

Before finialize this solution, there're some discussion on
the DMA mapping type(stream-based or coherent) in this KFD
migration case, followed by https://lore.kernel.org/all/04d4ab32
-45a1-4b88-86ee-fb0f35a0ca40@amd.com/T/.

As there's no dma_sync_single_for_*() in the DMA buffer accessed
that because this migration operation should be sync properly and
automatically. Give that there's might not be a performance problem
in various cache sync policy of DMA sync. Therefore, in order to
simplify the DMA direction setting alignment, let's set the DMA map
direction as BIDIRECTIONAL.

[PATCH AUTOSEL 6.12 07/29] ALSA: hda: cs35l56: Remove calls to cs35l56_force_sync_asp1_registers_from_cache()

[Sasha Levin]

From: Simon Trimmer <simont@opensource.cirrus.com>

[ Upstream commit 47b17ba05a463b22fa79f132e6f6899d53538802 ]

Commit 5d7e328e20b3 ("ASoC: cs35l56: Revert support for dual-ownership
of ASP registers")
replaced cs35l56_force_sync_asp1_registers_from_cache() with a dummy
implementation so that the HDA driver would continue to build.

Remove the calls from HDA and remove the stub function.

[PATCH AUTOSEL 6.12 08/29] ALSA: hda/realtek - Add support for ASUS Zen AIO 27 Z272SD_A272SD audio

[Sasha Levin]

From: Vasiliy Kovalev <kovalev@altlinux.org>

[ Upstream commit 1b452c2de5555d832cd51c46824272a44ad7acac ]

Introduces necessary quirks to enable audio functionality on the
ASUS Zen AIO 27 Z272SD_A272SD:
- configures verbs to activate internal speakers and headphone jack.
- implements adjustments for headset microphone functionality.

The speaker and jack configurations were derived from a dump of
the working Windows driver, while the headset microphone
functionality was fine-tuned through experimental testing.

[PATCH AUTOSEL 6.12 09/29] btrfs: handle bio_split() errors

[Sasha Levin]

From: Johannes Thumshirn <johannes.thumshirn@wdc.com>

[ Upstream commit c7c97ceff98cc459bf5e358e5cbd06fcb651d501 ]

Commit e546fe1da9bd ("block: Rework bio_split() return value") changed
bio_split() so that it can return errors.

Add error handling for it in btrfs_split_bio() and ultimately
btrfs_submit_chunk(). As the bio is not submitted, the bio counter must
be decremented to pair btrfs_bio_counter_inc_blocked().

[PATCH AUTOSEL 6.12 10/29] btrfs: flush delalloc workers queue before stopping cleaner kthread during unmount

[Sasha Levin]

From: Filipe Manana <fdmanana@suse.com>

[ Upstream commit f10bef73fb355e3fc85e63a50386798be68ff486 ]

During the unmount path, at close_ctree(), we first stop the cleaner
kthread, using kthread_stop() which frees the associated task_struct, and
then stop and destroy all the work queues. However after we stopped the
cleaner we may still have a worker from the delalloc_workers queue running
inode.c:submit_compressed_extents(), which calls btrfs_add_delayed_iput(),
which in turn tries to wake up the cleaner kthread - which was already
destroyed before, resulting in a use-after-free on the task_struct.

Syzbot reported this with the following stack traces:

[PATCH AUTOSEL 6.12 11/29] ALSA: hda/ca0132: Use standard HD-audio quirk matching helpers

[Sasha Levin]

From: Takashi Iwai <tiwai@suse.de>

[ Upstream commit 7c005292e20ac53dfa601bf2a7375fd4815511ad ]

CA0132 used the PCI SSID lookup helper that doesn't support the model
string matching or quirk aliasing.

Replace it with the standard HD-audio quirk helpers for supporting
those, and add the definition of the model strings for supported
quirks, too.  There should be no visible change to the outside for the
working system, but the driver will parse the model option and apply
the quirk based on it from now on.

[PATCH AUTOSEL 6.12 12/29] ALSA: hda/realtek: Add new alc2xx-fixup-headset-mic model

[Sasha Levin]

From: Vasiliy Kovalev <kovalev@altlinux.org>

[ Upstream commit 50db91fccea0da5c669bc68e2429e8de303758d3 ]

Introduces the alc2xx-fixup-headset-mic model to simplify enabling
headset microphones on ALC2XX codecs.

Many recent configurations, as well as older systems that lacked this
fix for a long time, leave headset microphones inactive by default.
This addition provides a flexible workaround using the existing
ALC2XX_FIXUP_HEADSET_MIC quirk.

[PATCH AUTOSEL 6.12 14/29] sound: usb: format: don't warn that raw DSD is unsupported

[Sasha Levin]

From: Adrian Ratiu <adrian.ratiu@collabora.com>

[ Upstream commit b50a3e98442b8d72f061617c7f7a71f7dba19484 ]

UAC 2 & 3 DAC's set bit 31 of the format to signal support for a
RAW_DATA type, typically used for DSD playback.

This is correctly tested by (format & UAC*_FORMAT_TYPE_I_RAW_DATA),
fp->dsd_raw = true; and call snd_usb_interface_dsd_format_quirks(),
however a confusing and unnecessary message gets printed because
the bit is not properly tested in the last "unsupported" if test:
if (format & ~0x3F) { ... }

For example the output:

usb 7-1: new high-speed USB device number 5 using xhci_hcd
usb 7-1: New USB device found, idVendor=262a, idProduct=9302, bcdDevice=0.01
usb 7-1: New USB device strings: Mfr=1, Product=2, SerialNumber=6
usb 7-1: Product: TC44C
usb 7-1: Manufacturer: TC44C
usb 7-1: SerialNumber: 5000000001
hid-generic 0003:262A:9302.001E: No inputs registered, leaving
hid-generic 0003:262A:9302.001E: hidraw6: USB HID v1.00 Device [DDHIFI TC44C] on usb-0000:08:00.3-1/input0
usb 7-1: 2:4 : unsupported format bits 0x100000000

This last "unsupported format" is actually wrong: we know the
format is a RAW_DATA which we assume is DSD, so there is no need
to print the confusing message.

This we unset bit 31 of the format after recognizing it, to avoid
the message.

[PATCH AUTOSEL 6.12 17/29] ARC: build: disallow invalid PAE40 + 4K page config

[Sasha Levin]

From: Vineet Gupta <vgupta@kernel.org>

[ Upstream commit 8871331b1769978ecece205a430338a2581e5050 ]

The config option being built was
| CONFIG_ARC_MMU_V4=y
| CONFIG_ARC_PAGE_SIZE_4K=y
| CONFIG_HIGHMEM=y
| CONFIG_ARC_HAS_PAE40=y

This was hitting a BUILD_BUG_ON() since a 4K page can't hoist 1k, 8-byte
PTE entries (8 byte due to PAE40). BUILD_BUG_ON() is a good last ditch
resort, but such a config needs to be disallowed explicitly in Kconfig.

Side-note: the actual fix is single liner dependency, but while at it
cleaned out a few things:
 - 4K dependency on MMU v3 or v4 is always true, since 288ff7de62af09
   ("ARC: retire MMUv1 and MMUv2 support")
 - PAE40 dependency in on MMU ver not really ISA, although that follows
   eventually.

[PATCH AUTOSEL 6.12 18/29] ARC: build: Use __force to suppress per-CPU cmpxchg warnings

[Sasha Levin]

From: "Paul E. McKenney" <paulmck@kernel.org>

[ Upstream commit 1e8af9f04346ecc0bccf0c53b728fc8eb3490a28 ]

Currently, the cast of the first argument to cmpxchg_emu_u8() drops the
__percpu address-space designator, which results in sparse complaints
when applying cmpxchg() to per-CPU variables in ARC.  Therefore, use
__force to suppress these complaints, given that this does not pertain
to cmpxchg() semantics, which are plently well-defined on variables in
general, whether per-CPU or otherwise.

[PATCH AUTOSEL 6.12 19/29] ARC: bpf: Correct conditional check in 'check_jmp_32'

[Sasha Levin]

From: Hardevsinh Palaniya <hardevsinh.palaniya@siliconsignals.io>

[ Upstream commit 7dd9eb6ba88964b091b89855ce7d2a12405013af ]

The original code checks 'if (ARC_CC_AL)', which is always true since
ARC_CC_AL is a constant. This makes the check redundant and likely
obscures the intention of verifying whether the jump is conditional.

Updates the code to check cond == ARC_CC_AL instead, reflecting the intent
to differentiate conditional from unconditional jumps.

[PATCH AUTOSEL 6.12 20/29] bpf: fix potential error return

[Sasha Levin]

From: Anton Protopopov <aspsk@isovalent.com>

[ Upstream commit c4441ca86afe4814039ee1b32c39d833c1a16bbc ]

The bpf_remove_insns() function returns WARN_ON_ONCE(error), where
error is a result of bpf_adj_branches(), and thus should be always 0
However, if for any reason it is not 0, then it will be converted to
boolean by WARN_ON_ONCE and returned to user space as 1, not an actual
error value. Fix this by returning the original err after the WARN check.

[PATCH AUTOSEL 6.12 21/29] ksmbd: retry iterate_dir in smb2_query_dir

[Sasha Levin]

From: Hobin Woo <hobin.woo@samsung.com>

[ Upstream commit 2b904d61a97e8ba79e3bc216ba290fd7e1d85028 ]

Some file systems do not ensure that the single call of iterate_dir
reaches the end of the directory. For example, FUSE fetches entries from
a daemon using 4KB buffer and stops fetching if entries exceed the
buffer. And then an actor of caller, KSMBD, is used to fill the entries
from the buffer.
Thus, pattern searching on FUSE, files located after the 4KB could not
be found and STATUS_NO_SUCH_FILE was returned.

[PATCH AUTOSEL 6.12 26/29] irqchip/gic: Correct declaration of *percpu_base pointer in union gic_base

[Sasha Levin]

From: Uros Bizjak <ubizjak@gmail.com>

[ Upstream commit a1855f1b7c33642c9f7a01991fb763342a312e9b ]

percpu_base is used in various percpu functions that expect variable in
__percpu address space. Correct the declaration of percpu_base to

void __iomem * __percpu *percpu_base;

to declare the variable as __percpu pointer.

The patch fixes several sparse warnings:

irq-gic.c:1172:44: warning: incorrect type in assignment (different address spaces)
irq-gic.c:1172:44:    expected void [noderef] __percpu *[noderef] __iomem *percpu_base
irq-gic.c:1172:44:    got void [noderef] __iomem *[noderef] __percpu *
...
irq-gic.c:1231:43: warning: incorrect type in argument 1 (different address spaces)
irq-gic.c:1231:43:    expected void [noderef] __percpu *__pdata
irq-gic.c:1231:43:    got void [noderef] __percpu *[noderef] __iomem *percpu_base

There were no changes in the resulting object files.

[PATCH AUTOSEL 6.12 27/29] ARC: build: Try to guess GCC variant of cross compiler

[Sasha Levin]

From: Leon Romanovsky <leonro@nvidia.com>

[ Upstream commit 824927e88456331c7a999fdf5d9d27923b619590 ]

ARC GCC compiler is packaged starting from Fedora 39i and the GCC
variant of cross compile tools has arc-linux-gnu- prefix and not
arc-linux-. This is causing that CROSS_COMPILE variable is left unset.

This change allows builds without need to supply CROSS_COMPILE argument
if distro package is used.

Before this change:
$ make -j 128 ARCH=arc W=1 drivers/infiniband/hw/mlx4/
  gcc: warning: ‘-mcpu=’ is deprecated; use ‘-mtune=’ or ‘-march=’ instead
  gcc: error: unrecognized command-line option ‘-mmedium-calls’
  gcc: error: unrecognized command-line option ‘-mlock’

[PATCH AUTOSEL 6.12 28/29] bpf: refactor bpf_helper_changes_pkt_data to use helper number

[Sasha Levin]

From: Eduard Zingerman <eddyz87@gmail.com>

[ Upstream commit b238e187b4a2d3b54d80aec05a9cab6466b79dde ]

Use BPF helper number instead of function pointer in
bpf_helper_changes_pkt_data(). This would simplify usage of this
function in verifier.c:check_cfg() (in a follow-up patch),
where only helper number is easily available and there is no real need
to lookup helper proto.

[PATCH AUTOSEL 6.12 29/29] bpf: consider that tail calls invalidate packet pointers

[Sasha Levin]

From: Eduard Zingerman <eddyz87@gmail.com>

[ Upstream commit 1a4607ffba35bf2a630aab299e34dd3f6e658d70 ]

Tail-called programs could execute any of the helpers that invalidate
packet pointers. Hence, conservatively assume that each tail call
invalidates packet pointers.

Making the change in bpf_helper_changes_pkt_data() automatically makes
use of check_cfg() logic that computes 'changes_pkt_data' effect for
global sub-programs, such that the following program could be
rejected:

    int tail_call(struct __sk_buff *sk)
    {
    	bpf_tail_call_static(sk, &jmp_table, 0);
    	return 0;
    }

    SEC("tc")
    int not_safe(struct __sk_buff *sk)
    {
    	int *p = (void *)(long)sk->data;
    	... make p valid ...
    	tail_call(sk);
    	*p = 42; /* this is unsafe */
    	...
    }

The tc_bpf2bpf.c:subprog_tc() needs change: mark it as a function that
can invalidate packet pointers. Otherwise, it can't be freplaced with
tailcall_freplace.c:entry_freplace() that does a tail call.
