Cezary Rojewski 7b67eb0f70 ASoC: Intel: avs: Power and clock gating policy overriding
commit 2a87f17775 upstream.

Provide pgctl/cgctl_mask module parameters for overriding power and
clock gating policies respectively. These help deal with rare firmware
loading failures on some configurations. There're no golden masks that
cover all known problems so leave the defaults as is.

While at it, update avs_hda_l1sen_enable()'s definition so it aligns
with its power/clock friends.

Piotr Maziarz bffa954953 ASoC: Intel: avs: Standby power-state support
commit d56829e9c1 upstream.

Introduce avs_suspend_standby() and avs_resume_standby() to support S0IX
streaming. The AudioDSP is not shutdown during such scenario and the PCI
device is armed for possible wake operation through an audio event.

As capability for a stream to be active during low power S0 is based off
of ->ignore_suspend, adjust the field's value according to platform
capabilities if needed.

Cezary Rojewski 4863dded80 ASoC: Intel: avs: Introduce PCM power management routines
commit 2b9a50ea84 upstream.

Implement suspend/resume() operations for component drivers. For most
scenarios, the PM flow is similar to standard streaming one, except for
the part where the position register are being saved and the lack of PCM
pages freeing. To reduce code duplication, all avs_dai_suspend_XXX() and
avs_dai_resume_XXX() functions reuse their non-PM equivalents.

Given that path binding/unbinding happens only in FE part of the stream,
the order of suspend() goes:

1. hw_free() all FE DAIs, paths are unbound here
2. hw_free() all BE DAIs

Consequently, for resume() its:

1. hw_params() all BE DAIs
2. hw_params() all FE DAIs, paths are bound here
3. prepare() all BE DAIs
4. prepare() all FE DAIs

As component->suspend/resume() do not provide substream pointer, store
it ourselves so that the PM flow has all the necessary information to
proceed.

snd_pcm_lib_free_pages() from existing avs_dai_fe_hw_free() so that

Pierre-Louis Bossart 4d3a643ea0 ALSA/ASoC: hda: move SPIB/DRMS functionality from ext layer
commit 6258234129 upstream.

The SPIB and DRMS capabilities are orthogonal to the DSP enablement
and can be used whether the stream is coupled or not.

The existing code partitioning makes limited sense, the capabilities
are parsed at the sound/hda level but helpers are located in
sound/hda/ext.

This patch moves all the SPIB/DRMS functionality to the sound/hda
layer. This reduces the complexity of the sound/hda/ext layer which is
now limited to handling the multi-link extensions and stream
coupling/decoupling helpers.

Note that this is an iso-functionality code move and rename, the
HDaudio legacy driver would need additional changes to make use of
these capabilities.

commit f90025100f upstream.

commit 0b00a5615d ("ALSA: hdac_ext: add hdac extended controller")
introduced a for() loop on the number of HDaudio codecs that seems
completely useless.

a) the body of the loop does not make use of the loop index, and
b) the LSDIID register is related to the SDI line, so there can only
be one codec per multi-link descriptor.

Pierre-Louis Bossart c393b33a18 ALSA: hda: ext: reduce ambiguity between 'multi-link' and 'link' DMA
commit 26646c199b upstream.

My esteemed colleagues keep using the same words for different things.

The multi-link structure needs to be handled whether the DSP is
enabled or not.

The host and link DMAs are only relevant when the DSP is enabled.

Things get convoluted when there's an ambiguity between the LOSIDV
settings in the multi-link register space and the selection of the
stream_tag for the link DMA.

Clarify with a rename that the static functions used are related to
the host and link DMAs only.

No functionality change, pure rename.

Pierre-Louis Bossart 7bb1cefdf0 ALSA/ASoC: hda: ext: add 'bus' prefix for multi-link stream setting
commit 7fa403f2a0 upstream.

All the helpers dealing with multi-link configurations are located in
the hdac_ext_controller.c, except the two set/clear routines that
modify the LOSIDV registers.

For consistency, move the two helpers and add the 'bus' prefix. One
could argue that the 'ml' prefix might be more relevant but that would
be a larger code change.

No functionality change, just move and rename.

Bhanuprakash Modem 3dc5463d08 drm/i915/display/debugfs: New entry "DRRS capable" to i915_drrs_status
If the connected panel supports both DRRS & PSR, driver gives preference
to PSR ("DRRS enabled: no"). Even though the hardware supports DRRS,
IGT treats ("DRRS enabled: yes") as not capable.

Introduce a new entry "DRRS capable" to debugfs i915_drrs_status, so
that IGT will read the DRRS capability as "DRRS capable: yes".

Vinicius Costa Gomes 97999c2d49 igb: Fix missing time sync events
Fix "double" clearing of interrupts, which can cause external events
or timestamps to be missed.

The E1000_TSIRC Time Sync Interrupt Cause register can be cleared in two
ways, by either reading it or by writing '1' into the specific cause
bit. This is documented in section 8.16.1.

The following flow was used:
    1. read E1000_TSIRC into 'tsicr';
    2. handle the interrupts present into 'tsirc' and mark them in 'ack';
    3. write 'ack' into E1000_TSICR;

As both (1) and (3) will clear the interrupt cause, if the same
interrupt happens again between (1) and (3) it will be ignored,
causing events to be missed.

Remove the extra clear in (3).

Kuniyuki Iwashima f119f2325b arp: Prevent overflow in arp_req_get().
commit a7d6027790acea24446ddd6632d394096c0f4667 upstream.

syzkaller reported an overflown write in arp_req_get(). [0]

When ioctl(SIOCGARP) is issued, arp_req_get() looks up an neighbour
entry and copies neigh->ha to struct arpreq.arp_ha.sa_data.

The arp_ha here is struct sockaddr, not struct sockaddr_storage, so
the sa_data buffer is just 14 bytes.

In the splat below, 2 bytes are overflown to the next int field,
arp_flags.  We initialise the field just after the memcpy(), so it's
not a problem.

However, when dev->addr_len is greater than 22 (e.g. MAX_ADDR_LEN),
arp_netmask is overwritten, which could be set as htonl(0xFFFFFFFFUL)
in arp_ioctl() before calling arp_req_get().

To avoid the overflow, let's limit the max length of memcpy().

Note that commit b5f0de6df6 ("net: dev: Convert sa_data to flexible
array in struct sockaddr") just silenced syzkaller.

[0]:
memcpy: detected field-spanning write (size 16) of single field "r->arp_ha.sa_data" at net/ipv4/arp.c:1128 (size 14)

ASMedia have confirmed that all ASM106x parts currently listed in
ahci_pci_tbl[] suffer from the 43-bit DMA address limitation that we ran
into on the ASM1061, and therefore, we need to apply the quirk added by
commit 20730e9b2778 ("ahci: add 43-bit DMA address quirk for ASMedia
ASM1061 controllers") to the other supported ASM106x parts as well.

commit 584f3894262634596532cf43a5e782e34a0ce374 upstream.

Just the same as userspace PM, a new parameter needs_id is added for
in-kernel PM mptcp_pm_nl_append_new_local_addr() too.

Add a new helper mptcp_pm_has_addr_attr_id() to check whether an address
ID is set from PM or not.

In mptcp_pm_nl_get_local_id(), needs_id is always true, but in
mptcp_pm_nl_add_addr_doit(), pass mptcp_pm_has_addr_attr_id() to
needs_it.

commit 84c531f54ad9a124a924c9505d74e33d16965146 upstream.

This patch adds the ability to send RM_ADDR for local ID 0. Check
whether id 0 address is removed, if not, put id 0 into a removing
list, pass it to mptcp_pm_remove_addr() to remove id 0 address.

There is no reason not to allow the userspace to remove the initial
address (ID 0). This special case was not taken into account not
letting the userspace to delete all addresses as announced.

Yosry Ahmed 14f1992430 mm: zswap: fix missing folio cleanup in writeback race path
commit e3b63e966cac0bf78aaa1efede1827a252815a1d upstream.

In zswap_writeback_entry(), after we get a folio from
__read_swap_cache_async(), we grab the tree lock again to check that the
swap entry was not invalidated and recycled.  If it was, we delete the
folio we just added to the swap cache and exit.

However, __read_swap_cache_async() returns the folio locked when it is
newly allocated, which is always true for this path, and the folio is
ref'd.  Make sure to unlock and put the folio before returning.

This was discovered by code inspection, probably because this path handles
a race condition that should not happen often, and the bug would not crash
the system, it will only strand the folio indefinitely.

SeongJae Park 7ebeee513f mm/damon/reclaim: fix quota stauts loss due to online tunings
commit 1b0ca4e4ff10a2c8402e2cf70132c683e1c772e4 upstream.

Patch series "mm/damon: fix quota status loss due to online tunings".

DAMON_RECLAIM and DAMON_LRU_SORT is not preserving internal quota status
when applying new user parameters, and hence could cause temporal quota
accuracy degradation.  Fix it by preserving the status.


This patch (of 2):

For online parameters change, DAMON_RECLAIM creates new scheme based on
latest values of the parameters and replaces the old scheme with the new
one.  When creating it, the internal status of the quota of the old
scheme is not preserved.  As a result, charging of the quota starts from
zero after the online tuning.  The data that collected to estimate the
throughput of the scheme's action is also reset, and therefore the
estimation should start from the scratch again.  Because the throughput
estimation is being used to convert the time quota to the effective size
quota, this could result in temporal time quota inaccuracy.  It would be
recovered over time, though.  In short, the quota accuracy could be
temporarily degraded after online parameters update.

Fix the problem by checking the case and copying the internal fields for
the status.

Gao Xiang 47467e0481 erofs: fix inconsistent per-file compression format
commit 118a8cf504d7dfa519562d000f423ee3ca75d2c4 upstream.

EROFS can select compression algorithms on a per-file basis, and each
per-file compression algorithm needs to be marked in the on-disk
superblock for initialization.

However, syzkaller can generate inconsistent crafted images that use
an unsupported algorithmtype for specific inodes, e.g. use MicroLZMA
algorithmtype even it's not set in `sbi->available_compr_algs`.  This
can lead to an unexpected "BUG: kernel NULL pointer dereference" if
the corresponding decompressor isn't built-in.

Fix this by checking against `sbi->available_compr_algs` for each
m_algorithmformat request.  Incorrect !erofs_sb_has_compr_cfgs preset
bitmap is now fixed together since it was harmless previously.

Erik Kurzinger fd7b4f4fdc drm/syncobj: call drm_syncobj_fence_add_wait when WAIT_AVAILABLE flag is set
[ Upstream commit 3c43177ffb54ea5be97505eb8e2690e99ac96bc9 ]

When waiting for a syncobj timeline point whose fence has not yet been
submitted with the WAIT_FOR_SUBMIT flag, a callback is registered using
drm_syncobj_fence_add_wait and the thread is put to sleep until the
timeout expires. If the fence is submitted before then,
drm_syncobj_add_point will wake up the sleeping thread immediately which
will proceed to wait for the fence to be signaled.

However, if the WAIT_AVAILABLE flag is used instead,
drm_syncobj_fence_add_wait won't get called, meaning the waiting thread
will always sleep for the full timeout duration, even if the fence gets
submitted earlier. If it turns out that the fence *has* been submitted
by the time it eventually wakes up, it will still indicate to userspace
that the wait completed successfully (it won't return -ETIME), but it
will have taken much longer than it should have.

To fix this, we must call drm_syncobj_fence_add_wait if *either* the
WAIT_FOR_SUBMIT flag or the WAIT_AVAILABLE flag is set. The only
difference being that with WAIT_FOR_SUBMIT we will also wait for the
fence to be signaled after it has been submitted while with
WAIT_AVAILABLE we will return immediately.
