[PATCH AUTOSEL 6.1 02/38] ASoC: SOF: sof-audio: start with the right widget type

[Sasha Levin]

From: Bard Liao <yung-chuan.liao@linux.intel.com>

[ Upstream commit fcc4348adafe53928fda46d104c1798e5a4de4ff ]

If there is a connection between a playback stream and a capture stream,
all widgets that are connected to the playback stream and the capture
stream will be in the list.
So, we have to start with the exactly right widget type.
snd_soc_dapm_aif_out is for capture stream and a playback stream should
start with a snd_soc_dapm_aif_in widget.
Contrarily, snd_soc_dapm_dai_in is for playback stream, and a capture
stream should start with a snd_soc_dapm_dai_out widget.

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

[ Upstream commit 324f065cdbaba1b879a63bf07e61ca156b789537 ]

The amplifier may provide hardware support for I/V feedback, or
alternatively the firmware may generate an echo reference attached to
the SSP and dailink used for the amplifier.

To avoid any issues with invalid/NULL substreams in the latter case,
always unconditionally set dpcm_capture.

[PATCH AUTOSEL 6.1 09/38] ALSA: hda: Do not unset preset when cleaning up codec

[Sasha Levin]

From: Cezary Rojewski <cezary.rojewski@intel.com>

[ Upstream commit 87978e6ad45a16835cc58234451111091be3c59a ]

Several functions that take part in codec's initialization and removal
are re-used by ASoC codec drivers implementations. Drivers mimic the
behavior of hda_codec_driver_probe/remove() found in
sound/pci/hda/hda_bind.c with their component->probe/remove() instead.

One of the reasons for that is the expectation of
snd_hda_codec_device_new() to receive a valid pointer to an instance of
struct snd_card. This expectation can be met only once sound card
components probing commences.

As ASoC sound card may be unbound without codec device being actually
removed from the system, unsetting ->preset in
snd_hda_codec_cleanup_for_unbind() interferes with module unload -> load
scenario causing null-ptr-deref. Preset is assigned only once, during
device/driver matching whereas ASoC codec driver's module reloading may
occur several times throughout the lifetime of an audio stack.

[PATCH AUTOSEL 6.1 11/38] bpf, sockmap: Don't let sock_map_{close,destroy,unhash} call itself

[Sasha Levin]

From: Jakub Sitnicki <jakub@cloudflare.com>

[ Upstream commit 5b4a79ba65a1ab479903fff2e604865d229b70a9 ]

sock_map proto callbacks should never call themselves by design. Protect
against bugs like [1] and break out of the recursive loop to avoid a stack
overflow in favor of a resource leak.

[PATCH AUTOSEL 6.1 12/38] ASoC: cs42l56: fix DT probe

[Sasha Levin]

From: Arnd Bergmann <arnd@arndb.de>

[ Upstream commit e18c6da62edc780e4f4f3c9ce07bdacd69505182 ]

While looking through legacy platform data users, I noticed that
the DT probing never uses data from the DT properties, as the
platform_data structure gets overwritten directly after it
is initialized.

There have never been any boards defining the platform_data in
the mainline kernel either, so this driver so far only worked
with patched kernels or with the default values.

For the benefit of possible downstream users, fix the DT probe
by no longer overwriting the data.

[PATCH AUTOSEL 6.1 15/38] net/rose: Fix to not accept on connected socket

[Sasha Levin]

From: Hyunwoo Kim <v4bel@theori.io>

[ Upstream commit 14caefcf9837a2be765a566005ad82cd0d2a429f ]

If you call listen() and accept() on an already connect()ed
rose socket, accept() can successfully connect.
This is because when the peer socket sends data to sendmsg,
the skb with its own sk stored in the connected socket's
sk->sk_receive_queue is connected, and rose_accept() dequeues
the skb waiting in the sk->sk_receive_queue.

This creates a child socket with the sk of the parent
rose socket, which can cause confusion.

Fix rose_listen() to return -EINVAL if the socket has
already been successfully connected, and add lock_sock
to prevent this issue.

[PATCH AUTOSEL 6.1 16/38] selftest: net: Improve IPV6_TCLASS/IPV6_HOPLIMIT tests apparmor compatibility

[Sasha Levin]

From: Andrei Gherzan <andrei.gherzan@canonical.com>

[ Upstream commit a6efc42a86c0c87cfe2f1c3d1f09a4c9b13ba890 ]

"tcpdump" is used to capture traffic in these tests while using a random,
temporary and not suffixed file for it. This can interfere with apparmor
configuration where the tool is only allowed to read from files with
'known' extensions.

The MINE type application/vnd.tcpdump.pcap was registered with IANA for
pcap files and .pcap is the extension that is both most common but also
aligned with standard apparmor configurations. See TCPDUMP(8) for more
details.

This improves compatibility with standard apparmor configurations by
using ".pcap" as the file extension for the tests' temporary files.

[PATCH AUTOSEL 6.1 18/38] powerpc/kvm: Fix unannotated intra-function call warning

[Sasha Levin]

From: Sathvika Vasireddy <sv@linux.ibm.com>

[ Upstream commit fe6de81b610e5d0b9d2231acff2de74a35482e7d ]

objtool throws the following warning:
  arch/powerpc/kvm/booke.o: warning: objtool: kvmppc_fill_pt_regs+0x30:
  unannotated intra-function call

Fix the warning by setting the value of 'nip' using the _THIS_IP_ macro,
without using an assembly bl/mflr sequence to save the instruction
pointer.

[PATCH AUTOSEL 6.1 19/38] net: stmmac: do not stop RX_CLK in Rx LPI state for qcs404 SoC

[Sasha Levin]

From: Andrey Konovalov <andrey.konovalov@linaro.org>

[ Upstream commit 54aa39a513dbf2164ca462a19f04519b2407a224 ]

Currently in phy_init_eee() the driver unconditionally configures the PHY
to stop RX_CLK after entering Rx LPI state. This causes an LPI interrupt
storm on my qcs404-base board.

Change the PHY initialization so that for "qcom,qcs404-ethqos" compatible
device RX_CLK continues to run even in Rx LPI state.

[PATCH AUTOSEL 6.1 20/38] powerpc/64: Fix perf profiling asynchronous interrupt handlers

[Sasha Levin]

From: Nicholas Piggin <npiggin@gmail.com>

[ Upstream commit c28548012ee2bac55772ef7685138bd1124b80c3 ]

Interrupt entry sets the soft mask to IRQS_ALL_DISABLED to match the
hard irq disabled state. So when should_hard_irq_enable() returns true
because we want PMI interrupts in irq handlers, MSR[EE] is enabled but
PMIs just get soft-masked. Fix this by clearing IRQS_PMI_DISABLED before
enabling MSR[EE].

This also tidies some of the warnings, no need to duplicate them in
both should_hard_irq_enable() and do_hard_irq_enable().

[PATCH AUTOSEL 6.1 21/38] fscache: Use clear_and_wake_up_bit() in fscache_create_volume_work()

[Sasha Levin]

From: Hou Tao <houtao1@huawei.com>

[ Upstream commit 3288666c72568fe1cc7f5c5ae33dfd3ab18004c8 ]

fscache_create_volume_work() uses wake_up_bit() to wake up the processes
which are waiting for the completion of volume creation. According to
comments in wake_up_bit() and waitqueue_active(), an extra smp_mb() is
needed to guarantee the memory order between FSCACHE_VOLUME_CREATING
flag and waitqueue_active() before invoking wake_up_bit().

Fixing it by using clear_and_wake_up_bit() to add the missing memory
barrier.

[PATCH AUTOSEL 6.1 22/38] drm/nouveau/devinit/tu102-: wait for GFW_BOOT_PROGRESS == COMPLETED

[Sasha Levin]

From: Ben Skeggs <bskeggs@redhat.com>

[ Upstream commit d22915d22ded21fd5b24b60d174775789f173997 ]

Starting from Turing, the driver is no longer responsible for initiating
DEVINIT when required as the GPU started loading a FW image from ROM and
executing DEVINIT itself after power-on.

However - we apparently still need to wait for it to complete.

This should correct some issues with runpm on some systems, where we get
control of the HW before it's been fully reinitialised after resume from
suspend.

[PATCH AUTOSEL 6.1 23/38] net: ethernet: mtk_eth_soc: Avoid truncating allocation

[Sasha Levin]

From: Kees Cook <keescook@chromium.org>

[ Upstream commit f3eceaed9edd7c0e0d9fb057613131f92973626f ]

There doesn't appear to be a reason to truncate the allocation used for
flow_info, so do a full allocation and remove the unused empty struct.
GCC does not like having a reference to an object that has been
partially allocated, as bounds checking may become impossible when
such an object is passed to other code. Seen with GCC 13:

../drivers/net/ethernet/mediatek/mtk_ppe.c: In function 'mtk_foe_entry_commit_subflow':
../drivers/net/ethernet/mediatek/mtk_ppe.c:623:18: warning: array subscript 'struct mtk_flow_entry[0]' is partly outside array bounds of 'unsigned char[48]' [-Warray-bounds=]

[PATCH AUTOSEL 6.1 25/38] s390/decompressor: specify __decompress() buf len to avoid overflow

[Sasha Levin]

From: Vasily Gorbik <gor@linux.ibm.com>

[ Upstream commit 7ab41c2c08a32132ba8c14624910e2fe8ce4ba4b ]

Historically calls to __decompress() didn't specify "out_len" parameter
on many architectures including s390, expecting that no writes beyond
uncompressed kernel image are performed. This has changed since commit
2aa14b1ab2c4 ("zstd: import usptream v1.5.2") which includes zstd library
commit 6a7ede3dfccb ("Reduce size of dctx by reutilizing dst buffer
(#2751)"). Now zstd decompression code might store literal buffer in
the unwritten portion of the destination buffer. Since "out_len" is
not set, it is considered to be unlimited and hence free to use for
optimization needs. On s390 this might corrupt initrd or ipl report
which are often placed right after the decompressor buffer. Luckily the
size of uncompressed kernel image is already known to the decompressor,
so to avoid the problem simply specify it in the "out_len" parameter.

[PATCH AUTOSEL 6.1 26/38] nvme-fc: fix a missing queue put in nvmet_fc_ls_create_association

[Sasha Levin]

From: Amit Engel <Amit.Engel@dell.com>

[ Upstream commit 0cab4404874f2de52617de8400c844891c6ea1ce ]

As part of nvmet_fc_ls_create_association there is a case where
nvmet_fc_alloc_target_queue fails right after a new association with an
admin queue is created. In this case, no one releases the get taken in
nvmet_fc_alloc_target_assoc.  This fix is adding the missing put.

[PATCH AUTOSEL 6.1 27/38] nvme: clear the request_queue pointers on failure in nvme_alloc_admin_tag_set

[Sasha Levin]

From: Maurizio Lombardi <mlombard@redhat.com>

[ Upstream commit fd62678ab55cb01e11a404d302cdade222bf4022 ]

If nvme_alloc_admin_tag_set() fails, the admin_q and fabrics_q pointers
are left with an invalid, non-NULL value. Other functions may then check
the pointers and dereference them, e.g. in

  nvme_probe() -> out_disable: -> nvme_dev_remove_admin().

Fix the bug by setting admin_q and fabrics_q to NULL in case of error.

Also use the set variable to free the tag_set as ctrl->admin_tagset isn't
initialized yet.

to us rerunning every command that's presently in the ringbuffer.

[How]
Reset software state for the mailboxes in hw_reset callback.
This is already done as part of the mailbox init in hw_init, but we
do need to remember to reset the last cached wptr value as well here.

[PATCH AUTOSEL 6.1 35/38] drm/amd/display: Properly handle additional cases where DCN is not supported

[Sasha Levin]

From: Alex Deucher <alexander.deucher@amd.com>

[ Upstream commit 6fc547a5a2ef5ce05b16924106663ab92f8f87a7 ]

There could be boards with DCN listed in IP discovery, but no
display hardware actually wired up.  In this case the vbios
display table will not be populated.  Detect this case and
skip loading DM when we detect it.

v2: Mark DCN as harvested as well so other display checks
elsewhere in the driver are handled properly.

[PATCH AUTOSEL 6.1 38/38] ceph: blocklist the kclient when receiving corrupted snap trace

[Sasha Levin]

From: Xiubo Li <xiubli@redhat.com>

[ Upstream commit a68e564adcaa69b0930809fb64d9d5f7d9c32ba9 ]

When received corrupted snap trace we don't know what exactly has
happened in MDS side. And we shouldn't continue IOs and metadatas
access to MDS, which may corrupt or get incorrect contents.

This patch will just block all the further IO/MDS requests
immediately and then evict the kclient itself.

The reason why we still need to evict the kclient just after
blocking all the further IOs is that the MDS could revoke the caps
faster.
