take some time to fill up the rest of the words in the MU, a timeout of
100us is arbritrary and too short. While waiting for Linux to consume the

This is a workaround for allowing dm-crypt crypto operations to be

LF-3093-1 crypto: caam/jr - fix caam-keygen exit / clean-up
Introduction
===
Currently we are facing some limitations in the caam/jr module lifecycle.
There are some discussion in upstream:
Link: https://lore.kernel.org/linux-crypto/20190904023515.7107-13-andrew.smirnov@gmail.com
Link: https://lore.kernel.org/linux-crypto/20191105151353.6522-1-andrew.smirnov@gmail.com
but in the end it all seems to get down to implementations not being able
to gracefully unregister crypto algorithms from crypto API while there are
users / allocated tfms (cra_refcnt > 1).
[*] OTOH functionalities in caam/jr that don't interact with crypto API
(like Secure Memory or black keys / blobs generation) don't face this
limitation.
Issue at hand
===
When unloading the caam_jr module, the .remove callback for the last JR
device exits with -EBUSY (see "Introduction" above) and doesn't perform
the clean-up (crypto algorithms unregistering etc.).
One side effect of this is leeding to an oops, which occurs due to a
corruption in the linked list of "misc devices"
(drivers/char/misc.c - misc_list):
1. caam_jr module is unloaded without calling unregister_algs()->
caam_keygen_exit()->misc_deregister() for the last job ring device;
this leaves a dangling entry in the misc_list double-linked list
2. rng_core module is unloaded and calls misc_deregister(); this implies
removing the corresponding entry in the misc_list; while doing this the
dangling entry is accessed - which leads to an oops since the address is
no longer valid (address points to the caam_jr module address space,
but caam_jr has been previously unloaded).
Fix this by moving the clean-up of non-crypto related functionalities [*]
before crypto related ones.

commit
f6351c3f1c27c80535d76cac2299aec44c36291e upstream.
The old way of changing the conntrack hashsize runtime was through changing
the module param via file /sys/module/nf_conntrack/parameters/hashsize. This
was extended to sysctl change in commit
3183ab8997a4 ("netfilter: conntrack:
allow increasing bucket size via sysctl too").
The commit introduced second "user" variable nf_conntrack_htable_size_user
which shadow actual variable nf_conntrack_htable_size. When hashsize is
changed via module param this "user" variable isn't updated. This results in
sysctl net/netfilter/nf_conntrack_buckets shows the wrong value when users
update via the old way.
This patch fix the issue by always updating "user" variable when reading the
proc file. This will take care of changes to the actual variable without
sysctl need to be aware.

riscv: Trace irq on only interrupt is enabled
commit
7cd1af107a92eb63b93a96dc07406dcbc5269436 upstream.
We should call irq trace only if interrupt is going to be enabled during
excecption handling. Otherwise, it results in following warning during
boot with lock debugging enabled.

mm, slub: consider rest of partial list if acquire_slab() fails
commit
8ff60eb052eeba95cfb3efe16b08c9199f8121cf 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.

drm/i915/dsi: Use unconditional msleep for the panel_on_delay when there is no reset-deassert MIPI-sequence
commit
00cb645fd7e29bdd20967cd20fa8f77bcdf422f9 upstream.
Commit
25b4620ee822 ("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.

bnxt_en: Improve stats context resource accounting with RDMA driver loaded.
commit
869c4d5eb1e6fbda66aa790c48bdb946d71494a0 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.

scsi: ufs: Fix possible power drain during system suspend
commit
1d53864c3617f5235f891ca0fbe9347c4cd35d46 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.

NFS: Adjust fs_context error logging
commit
c98e9daa59a611ff4e163689815f40380c912415 upstream.
Several existing dprink()/dfprintk() calls were converted to use the new
mount API logging macros by commit
ce8866f0913f ("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().

pNFS: Mark layout for return if return-on-close was not sent
commit
67bbceedc9bb8ad48993a8bd6486054756d711f4 upstream.
If the layout return-on-close failed because the layoutreturn was never
sent, then we should mark the layout for return again.

pNFS: We want return-on-close to complete when evicting the inode
commit

If the inode is being evicted, it should be safe to run return-on-close,
so we should do it to ensure we don't inadvertently leak layout segments.

nvme-tcp: fix possible data corruption with bio merges
commit
ca1ff67d0fb14f39cf0cc5102b1fbcc3b14f6fb9 upstream.
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.

nvme: don't intialize hwmon for discovery controllers
commit
5ab25a32cd90ce561ac28b9302766e565d61304c upstream.
Discovery controllers usually don't support smart log page command.
So when we connect to the discovery controller we see this warning:
nvme nvme0: Failed to read smart log (error 24577)
nvme nvme0: new ctrl: NQN "nqn.2014-08.org.nvmexpress.discovery", addr 192.168.123.1:8009
nvme nvme0: Removing ctrl: NQN "nqn.2014-08.org.nvmexpress.discovery"
Introduce a new helper to understand if the controller is a discovery
controller and use this helper to skip nvme_init_hwmon (also use it in
other places that we check if the controller is a discovery controller).

nvmet-rdma: Fix NULL deref when setting pi_enable and traddr INADDR_ANY
commit
7a84665619bb5da8c8b6517157875a1fd7632014 upstream.
When setting port traddr to INADDR_ANY, the listening cm_id->device
is NULL. The associate IB device is known only when a connect request
event arrives, so checking T10-PI device capability should be done
at this stage.
