5b984e538b ALSA: firewire-tascam: Fix integer overflow in midi_port_work()
commit 9f65df9c58 upstream.

As snd_fw_async_midi_port.consume_bytes is unsigned int, and
NSEC_PER_SEC is 1000000000L, the second multiplication in

    port->consume_bytes * 8 * NSEC_PER_SEC / 31250

always overflows on 32-bit platforms, truncating the result.  Fix this
by precalculating "NSEC_PER_SEC / 31250", which is an integer constant.

Note that this assumes port->consume_bytes <= 16777.

0eb56457d2 dm: eliminate potential source of excessive kernel log noise
commit 0378c625af upstream.

There wasn't ever a real need to log an error in the kernel log for
ioctls issued with insufficient permissions. Simply return an error
and if an admin/user is sufficiently motivated they can enable DM's
dynamic debugging to see an explanation for why the ioctls were
disallowed.

f0cd3fba4e net: sunrpc: interpret the return value of kstrtou32 correctly
commit 86b53fbf08 upstream.

A return value of 0 means success. This is documented in lib/kstrtox.c.

This was found by trying to mount an NFS share from a link-local IPv6
address with the interface specified by its index:

  mount("[fe80::1%1]:/srv/nfs", "/mnt", "nfs", 0, "nolock,addr=fe80::1%1")

Before this commit this failed with EINVAL and also caused the following
message in dmesg:

  [...] NFS: bad IP address specified: addr=fe80::1%1

The syscall using the same address based on the interface name instead
of its index succeeds.

Credits for this patch go to my colleague Christian Speich, who traced
the origin of this bug to this line of code.

a9bc9c9320 iommu/vt-d: Fix unaligned addresses for intel_flush_svm_range_dev()
commit 2d6ffc63f1 upstream.

The VT-d hardware will ignore those Addr bits which have been masked by
the AM field in the PASID-based-IOTLB invalidation descriptor. As the
result, if the starting address in the descriptor is not aligned with
the address mask, some IOTLB caches might not invalidate. Hence people
will see below errors.

c8c01da728 mm, slub: consider rest of partial list if acquire_slab() fails
commit 8ff60eb052 upstream.

acquire_slab() fails if there is contention on the freelist of the page
(probably because some other CPU is concurrently freeing an object from
the page).  In that case, it might make sense to look for a different page
(since there might be more remote frees to the page from other CPUs, and
we don't want contention on struct page).

However, the current code accidentally stops looking at the partial list
completely in that case.  Especially on kernels without CONFIG_NUMA set,
this means that get_partial() fails and new_slab_objects() falls back to
new_slab(), allocating new pages.  This could lead to an unnecessary
increase in memory fragmentation.

54c9246a47 drm/i915/dsi: Use unconditional msleep for the panel_on_delay when there is no reset-deassert MIPI-sequence
commit 00cb645fd7 upstream.

Commit 25b4620ee8 ("drm/i915/dsi: Skip delays for v3 VBTs in vid-mode")
added an intel_dsi_msleep() helper which skips sleeping if the
MIPI-sequences have a version of 3 or newer and the panel is in vid-mode;
and it moved a bunch of msleep-s over to this new helper.

This was based on my reading of the big comment around line 730 which
starts with "Panel enable/disable sequences from the VBT spec.",
where the "v3 video mode seq" column does not have any wait t# entries.

Given that this code has been used on a lot of different devices without
issues until now, it seems that my interpretation of the spec here is
mostly correct.

But now I have encountered one device, an Acer Aspire Switch 10 E
SW3-016, where the panel will not light up unless we do actually honor the
panel_on_delay after exexuting the MIPI_SEQ_PANEL_ON sequence.

What seems to set this model apart is that it is lacking a
MIPI_SEQ_DEASSERT_RESET sequence, which is where the power-on
delay usually happens.

Fix the panel not lighting up on this model by using an unconditional
msleep(panel_on_delay) instead of intel_dsi_msleep() when there is
no MIPI_SEQ_DEASSERT_RESET sequence.

44693384c3 bnxt_en: Improve stats context resource accounting with RDMA driver loaded.
commit 869c4d5eb1 upstream.

The function bnxt_get_ulp_stat_ctxs() does not count the stats contexts
used by the RDMA driver correctly when the RDMA driver is freeing the
MSIX vectors.  It assumes that if the RDMA driver is registered, the
additional stats contexts will be needed.  This is not true when the
RDMA driver is about to unregister and frees the MSIX vectors.

This slight error leads to over accouting of the stats contexts needed
after the RDMA driver has unloaded.  This will cause some firmware
warning and error messages in dmesg during subsequent config. changes
or ifdown/ifup.

Fix it by properly accouting for extra stats contexts only if the
RDMA driver is registered and MSIX vectors have been successfully
requested.

4351cf25cb scsi: ufs: Fix possible power drain during system suspend
commit 1d53864c36 upstream.

Currently if device needs to do flush or BKOP operations, the device VCC
power is kept during runtime-suspend period.

However, if system suspend is happening while device is runtime-suspended,
such power may not be disabled successfully.

The reasons may be,

1. If current PM level is the same as SPM level, device will keep
   runtime-suspended by ufshcd_system_suspend().

2. Flush recheck work may not be scheduled successfully during system
   suspend period. If it can wake up the system, this is also not the
   intention of the recheck work.

To fix this issue, simply runtime-resume the device if the flush is allowed
during runtime suspend period. Flush capability will be disabled while
leaving runtime suspend, and also not be allowed in system suspend period.

We must ensure that we pass a layout segment to nfs_retry_commit() when

requests that should be committed to the DS will get committed to the
MDS.

e6ae16467a NFS: Adjust fs_context error logging
commit c98e9daa59 upstream.

Several existing dprink()/dfprintk() calls were converted to use the new
mount API logging macros by commit ce8866f091 ("NFS: Attach
supplementary error information to fs_context").  If the fs_context was
not created using fsopen() then it will not have had a log buffer
allocated for it, and the new mount API logging macros will wind up
calling printk().

This can result in syslog messages being logged where previously there
were none... most notably "NFS4: Couldn't follow remote path", which can
happen if the client is auto-negotiating a protocol version with an NFS
server that doesn't support the higher v4.x versions.

Convert the nfs_errorf(), nfs_invalf(), and nfs_warnf() macros to check
for the existence of the fs_context's log buffer and call dprintk() if
it doesn't exist.  Add nfs_ferrorf(), nfs_finvalf(), and nfs_warnf(),
which do the same thing but take an NFS debug flag as an argument and
call dfprintk().  Finally, modify the "NFS4: Couldn't follow remote
path" message to use nfs_ferrorf().

When a bio merges, we can get a request that spans multiple
bios, and the overall request payload size is the sum of
all bios. When we calculate how much we need to send
from the existing bio (and bvec), we did not take into
account the iov_iter byte count cap.

Since multipage bvecs support, bvecs can split in the middle
which means that when we account for the last bvec send we
should also take the iov_iter byte count cap as it might be
lower than the last bvec size.

commit 671ee4db95 upstream.

When the axg-tdm-interface was introduced, the backend DAI was marked as an
endpoint when DPCM was walking the DAPM graph to find a its BE.

It is no longer the case since this
commit 8dd26dff00 ("ASoC: dapm: Fix handling of custom_stop_condition on DAPM graph walks")
Because of this, when DPCM finds a BE it does everything it needs on the
DAIs but it won't power up the widgets between the FE and the BE if there
is no actual endpoint after the BE.

On meson-axg HWs, the loopback is a special DAI of the tdm-interface BE.
It is only linked to the dummy codec since there no actual HW after it.
>From the DAPM perspective, the DAI has no endpoint. Because of this, the TDM
decoder, which is a widget between the FE and BE is not powered up.

>From the user perspective, everything seems fine but no data is produced.

Connecting the Loopback DAI to a dummy DAPM endpoint solves the problem.

72c5ce8942 mm: don't put pinned pages into the swap cache
[ Upstream commit feb889fb40 ]

So technically there is nothing wrong with adding a pinned page to the
swap cache, but the pinning obviously means that the page can't actually
be free'd right now anyway, so it's a bit pointless.

However, the real problem is not with it being a bit pointless: the real
issue is that after we've added it to the swap cache, we'll try to unmap
the page.  That will succeed, because the code in mm/rmap.c doesn't know
or care about pinned pages.

Even the unmapping isn't fatal per se, since the page will stay around
in memory due to the pinning, and we do hold the connection to it using
the swap cache.  But when we then touch it next and take a page fault,
the logic in do_swap_page() will map it back into the process as a
possibly read-only page, and we'll then break the page association on
the next COW fault.

Honestly, this issue could have been fixed in any of those other places:
(a) we could refuse to unmap a pinned page (which makes conceptual
sense), or (b) we could make sure to re-map a pinned page writably in
do_swap_page(), or (c) we could just make do_wp_page() not COW the
pinned page (which was what we historically did before that "mm:
do_wp_page() simplification" commit).

But while all of them are equally valid models for breaking this chain,
not putting pinned pages into the swap cache in the first place is the
simplest one by far.

It's also the safest one: the reason why do_wp_page() was changed in the
first place was that getting the "can I re-use this page" wrong is so
fraught with errors.  If you do it wrong, you end up with an incorrectly
shared page.

As a result, using "page_maybe_dma_pinned()" in either do_wp_page() or
do_swap_page() would be a serious bug since it is only a (very good)
heuristic.  Re-using the page requires a hard black-and-white rule with
no room for ambiguity.

In contrast, saying "this page is very likely dma pinned, so let's not
add it to the swap cache and try to unmap it" is an obviously safe thing
to do, and if the heuristic might very rarely be a false positive, no
harm is done.

e558b38b5e x86/sev-es: Fix SEV-ES OUT/IN immediate opcode vc handling
[ Upstream commit a8f7e08a81 ]

The IN and OUT instructions with port address as an immediate operand
only use an 8-bit immediate (imm8). The current VC handler uses the
entire 32-bit immediate value but these instructions only set the first
bytes.

Cast the operand to an u8 for that.
