[ Upstream commit 9928f0a9e7c0cee3360ca1442b4001d34ad67556 ]
Drop "interrupt-names" property, since it is broken. The drivers/dma/mxs-dma.c
in Linux kernel does not use it, the property contains duplicate array entries
in existing DTs, and even malformed entries (gmpi, should have been gpmi). Get
rid of that optional property altogether.

[ Upstream commit 321da3dc1f3c92a12e3c5da934090d2992a8814c ]
It has been observed that some USB/UAS devices return generic properties
hardcoded in firmware for mode pages for a period of time after a device
has been discovered. The reported properties are either garbage or they do
not accurately reflect the characteristics of the physical storage device
attached in the case of a bridge.
Prior to commit 1e029397d12f ("scsi: sd: Reorganize DIF/DIX code to
avoid calling revalidate twice") we would call revalidate several
times during device discovery. As a result, incorrect values would
eventually get replaced with ones accurately describing the attached
storage. When we did away with the redundant revalidate pass, several
cases were reported where devices reported nonsensical values or would
end up in write-protected state.
An initial attempt at addressing this issue involved introducing a
delayed second revalidate invocation. However, this approach still
left some devices reporting incorrect characteristics.
Tasos Sahanidis debugged the problem further and identified that
introducing a READ operation prior to MODE SENSE fixed the problem and that
it wasn't a timing issue. Issuing a READ appears to cause the devices to
update their state to reflect the actual properties of the storage
media. Device properties like vendor, model, and storage capacity appear to
be correctly reported from the get-go. It is unclear why these devices
defer populating the remaining characteristics.
Match the behavior of a well known commercial operating system and
trigger a READ operation prior to querying device characteristics to
force the device to populate the mode pages.
The additional READ is triggered by a flag set in the USB storage and
UAS drivers. We avoid issuing the READ for other transport classes
since some storage devices identify Linux through our particular
discovery command sequence.

Move the SCSI execution functions to use a struct for passing in optional
args. This commit adds the new struct, temporarily converts scsi_execute()
and scsi_execute_req() ands a new helper, scsi_execute_cmd(), which takes
the scsi_exec_args struct.
There should be no change in behavior. We no longer allow users to pass in
any request->rq_flags value, but they were only passing in RQF_PM which we
do support by allowing users to pass in the BLK_MQ_REQ flags used by
blk_mq_alloc_request().
Subsequent commits will convert scsi_execute() and scsi_execute_req() users
to the new helpers then remove scsi_execute() and scsi_execute_req().

Stop calling drm_bridge_remove() for bridges allocated/managed by other
drivers in the remove paths of meson_encoder_{cvbs,dsi,hdmi}.
drm_bridge_remove() unregisters the bridge so it cannot be used
anymore. Doing so for bridges we don't own can lead to the video
pipeline not being able to come up after -EPROBE_DEFER of the VPU
because we're unregistering a bridge that's managed by another driver.
The other driver doesn't know that we have unregistered it's bridge
and on subsequent .probe() we're not able to find those bridges anymore
(since nobody re-creates them).
This fixes probe errors on Meson8b boards with the CVBS outputs enabled.

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.

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.

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.

[ 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.

[ Upstream commit 3489182b11d35f1944c1245fc9c4867cf622c50f ]
Commit bb726b753f75 ("net: phy: realtek: add support for
RTL8211F(D)(I)-VD-CG") extended support of the driver from the existing
support for RTL8211F(D)(I)-CG PHY to the newer RTL8211F(D)(I)-VD-CG PHY.
While that commit indicated that the RTL8211F_PHYCR2 register is not
supported by the "VD-CG" PHY model and therefore updated the corresponding
section in rtl8211f_config_init() to be invoked conditionally, the call to
"genphy_soft_reset()" was left as-is, when it should have also been invoked
conditionally. This is because the call to "genphy_soft_reset()" was first
introduced by the commit 0a4355c2b7f8 ("net: phy: realtek: add dt property
to disable CLKOUT clock") since the RTL8211F guide indicates that a PHY
reset should be issued after setting bits in the PHYCR2 register.
As the PHYCR2 register is not applicable to the "VD-CG" PHY model, fix the
rtl8211f_config_init() function by invoking "genphy_soft_reset()"
conditionally based on the presence of the "PHYCR2" register.

ioam6_fill_trace_data() writes inside the skb payload without ensuring
it's writeable (e.g., not cloned). This function is called both from the
input and output path. The output path (ioam6_iptunnel) already does the
check. This commit provides a fix for the input path, inside
ipv6_hop_ioam(). It also updates ip6_parse_tlv() to refresh the network
header pointer ("nh") when returning from ipv6_hop_ioam().

[ Upstream commit 603ead96582d85903baec2d55f021b8dac5c25d2 ]
Both registers used when doing manual injection or fdma injection are
shared between all the net devices of the switch. It was noticed that
when having two process which each of them trying to inject frames on
different ethernet ports, that the HW started to behave strange, by
sending out more frames then expected. When doing fdma injection it is
required to set the frame in the DCB and then make sure that the next
pointer of the last DCB is invalid. But because there is no locks for
this, then easily this pointer between the DCB can be broken and then it
would create a loop of DCBs. And that means that the HW will
continuously transmit these frames in a loop. Until the SW will break
this loop.
Therefore to fix this issue, add a spin lock for when accessing the
registers for manual or fdma injection.

If we queue 3 records:
- record 1, type DATA
- record 2, some other type
- record 3, type DATA
and do a recv(PEEK), the rx_list will contain the first two records.
The next large recv will walk through the rx_list and copy data from
record 1, then stop because record 2 is a different type. Since we
haven't filled up our buffer, we will process the next available
record. It's also DATA, so we can merge it with the current read.
We shouldn't do that, since there was a record in between that we
ignored.
Add a flag to let process_rx_list inform tls_sw_recvmsg that it had
more data available.

- process_rx_list copies the non-DATA record

[ Upstream commit 10f41d0710fc81b7af93fa6106678d57b1ff24a7 ]
PEEK needs to leave decrypted records on the rx_list so that we can
receive them later on, so it jumps back into the async code that
queues the skb. Unfortunately that makes us skip the
TLS_RECORD_TYPE_DATA check at the bottom of the main loop, so if two
records of the same (non-DATA) type are queued, we end up merging
them.
Add the same record type check, and make it unlikely to not penalize
the async fastpath. Async decrypt only applies to data record, so this
check is only needed for PEEK.
process_rx_list also has similar issues.

the actions of the rules installed by PF/VF with corresponding

PF/VF for features like RX VLAN offload and DMAC filters but
rules involving action like drop/forward to queue are also
getting modified by AF. Hence fix it by setting the default

This happens because thinkpad-acpi always assumes that
convert_dytc_to_profile() successfully updated the profile. On the
contrary a condition can occur that when dytc_profile_refresh() is called
the profile doesn't get updated as there is a -EOPNOTSUPP branch.
