339fee69a1 ext4: fix rbtree traversal bug in ext4_mb_use_preallocated
[ Upstream commit 9d3de7ee19 ]

During allocations, while looking for preallocations(PA) in the per
inode rbtree, we can't do a direct traversal of the tree because
ext4_mb_discard_group_preallocation() can paralelly mark the pa deleted
and that can cause direct traversal to skip some entries. This was
leading to a BUG_ON() being hit [1] when we missed a PA that could satisfy
our request and ultimately tried to create a new PA that would overlap
with the missed one.

To makes sure we handle that case while still keeping the performance of
the rbtree, we make use of the fact that the only pa that could possibly
overlap the original goal start is the one that satisfies the below
conditions:

  1. It must have it's logical start immediately to the left of
  (ie less than) original logical start.

  2. It must not be deleted

To find this pa we use the following traversal method:

1. Descend into the rbtree normally to find the immediate neighboring
PA. Here we keep descending irrespective of if the PA is deleted or if
it overlaps with our request etc. The goal is to find an immediately
adjacent PA.

2. If the found PA is on right of original goal, use rb_prev() to find
the left adjacent PA.

3. Check if this PA is deleted and keep moving left with rb_prev() until
a non deleted PA is found.

4. This is the PA we are looking for. Now we can check if it can satisfy
the original request and proceed accordingly.

This approach also takes care of having deleted PAs in the tree.

(While we are at it, also fix a possible overflow bug in calculating the
end of a PA)

a0f2ba1866 ext4: mballoc: Remove useless setting of ac_criteria
[ Upstream commit 569f196f1e ]

There will be changes coming in future patches which will introduce a new
criteria for block allocation. This removes the useless setting of ac_criteria.
AFAIU, this might be only used to differentiate between whether a preallocated
blocks was allocated or was regular allocator called for allocating blocks.
Hence this also adds the debug prints to identify what type of block allocation
was done in ext4_mb_show_ac().

d254d88140 ext4: add EXT4_MB_HINT_GOAL_ONLY test in ext4_mb_use_preallocated
[ Upstream commit 1eff590489 ]

ext4_mb_use_preallocated will ignore the demand to alloc goal blocks,
although the EXT4_MB_HINT_GOAL_ONLY is requested.
For group pa, ext4_mb_group_or_file will not set EXT4_MB_HINT_GROUP_ALLOC
if EXT4_MB_HINT_GOAL_ONLY is set. So we will not alloc goal blocks from
group pa if EXT4_MB_HINT_GOAL_ONLY is set.
For inode pa, ext4_mb_pa_goal_check is added to check if free extent in
found inode pa meets goal blocks when EXT4_MB_HINT_GOAL_ONLY is set.

8e2fd3a158 drm/amd/display: update extended blank for dcn314 onwards
[ Upstream commit 469a62938a ]

[Why]
Flickering and underflow was observed when testing extended
blank on dcn314.

[What]
Vstartup is contrainted by vblank_nom, so adjusting it to include
non-adjusted vtotal in its calculation during freesync video
means that Vstartup is not changed when vtotal changes.
This fixed the flickering + underflow.

dc_extended_blank_supported function was removed
because extended blank is only relevant to when
zstate is supported. The increased vtotal during
freesync can be passed to dml regardless of whether
extended blank is supported or not, so this function is
not needed.

Updates were made recently in dml to the calculation of
min_dst_y_next_start. Dml input for dcn314 will now
always use the newer calculation for min_dst_y_next_start.
Dml input for older dcn versions remains untouched.

The variable optimized_min_dst_y_next_start
is replaced everywhere with min_dst_y_next_start,
and the updated dml allows min_dst_y_next_start to
increase to an optimized value during freesync video,
then return to default when freesync is disengaged.

Also removed registry key for controlling
extended blank feature.

544c121cae PCI: rockchip: Fix window mapping and address translation for endpoint
[ Upstream commit dc73ed0f1b ]

The RK3399 PCI endpoint core has 33 windows for PCIe space, now in the
driver up to 32 fixed size (1M) windows are used and pages are allocated
and mapped accordingly. The driver first used a single window and allocated
space inside which caused translation issues (between CPU space and PCI
space) because a window can only have a single translation at a given
time, which if multiple pages are allocated inside will cause conflicts.
Now each window is a single region of 1M which will always guarantee that
the translation is not in conflict.

Set the translation register addresses for physical function. As documented
in the technical reference manual (TRM) section 17.5.5 "PCIe Address
Translation" and section 17.6.8 "Address Translation Registers Description"

50cafe0581 btrfs: fix race between quota disable and relocation
[ Upstream commit 8a4a0b2a3e ]

If we disable quotas while we have a relocation of a metadata block group
that has extents belonging to the quota root, we can cause the relocation
to fail with -ENOENT. This is because relocation builds backref nodes for
extents of the quota root and later needs to walk the backrefs and access
the quota root - however if in between a task disables quotas, it results
in deleting the quota root from the root tree (with btrfs_del_root(),
called from btrfs_quota_disable().

This can be sporadically triggered by test case btrfs/255 from fstests:

  $ ./check btrfs/255

To fix this make the quota disable operation take the cleaner mutex, as
relocation of a block group also takes this mutex. This is also what we
do when deleting a subvolume/snapshot, we take the cleaner mutex in the
cleaner kthread (at cleaner_kthread()) and then we call btrfs_del_root()
at btrfs_drop_snapshot() while under the protection of the cleaner mutex.

384d3da611 io_uring: don't audit the capability check in io_uring_create()
[ Upstream commit 6adc2272aa ]

The check being unconditional may lead to unwanted denials reported by
LSMs when a process has the capability granted by DAC, but denied by an
LSM. In the case of SELinux such denials are a problem, since they can't
be effectively filtered out via the policy and when not silenced, they
produce noise that may hide a true problem or an attack.

Since not having the capability merely means that the created io_uring
context will be accounted against the current user's RLIMIT_MEMLOCK
limit, we can disable auditing of denials for this check by using
ns_capable_noaudit() instead of capable().

Commit 8ef7b9e176 ("powerpc/pseries/vas: Close windows with DLPAR

close window in the hypervisor for migration or DLPAR core removal
events. So holds mmap_mutex and then mmap lock before unmap the
paste address. But if the user space issue mmap paste address at
the same time with the migration event, coproc_mmap() is called
after holding the mmap lock which can trigger deadlock when trying
to acquire mmap_mutex in coproc_mmap().

7bbda96776 blk-mq: Fix stall due to recursive flush plug
[ Upstream commit 7090426351 ]

We have seen rare IO stalls as follows:

* blk_mq_plug_issue_direct() is entered with an mq_list containing two
requests.
* For the first request, it sets last == false and enters the driver's
queue_rq callback.
* The driver queue_rq callback indirectly calls schedule() which calls
blk_flush_plug(). This may happen if the driver has the
BLK_MQ_F_BLOCKING flag set and is allowed to sleep in ->queue_rq.
* blk_flush_plug() handles the remaining request in the mq_list. mq_list
is now empty.
* The original call to queue_rq resumes (with last == false).
* The loop in blk_mq_plug_issue_direct() terminates because there are no
remaining requests in mq_list.

The IO is now stalled because the last request submitted to the driver
had last == false and there was no subsequent call to commit_rqs().

Fix this by returning early in blk_mq_flush_plug_list() if rq_count is 0
which it will be in the recursive case, rather than checking if the
mq_list is empty. At the same time, adjust one of the callers to skip
the mq_list empty check as it is not necessary.

Fix it by checking for the successfull initialisation of kvm_arm_init()
in finalize_pkvm() before proceeding any futher.

3e5ea6b6a5 jbd2: Fix wrongly judgement for buffer head removing while doing checkpoint
[ Upstream commit e34c8dd238 ]

Following process,

jbd2_journal_commit_transaction
// there are several dirty buffer heads in transaction->t_checkpoint_list
          P1                   wb_workfn
jbd2_log_do_checkpoint
 if (buffer_locked(bh)) // false
                            __block_write_full_page
                             trylock_buffer(bh)
                             test_clear_buffer_dirty(bh)
 if (!buffer_dirty(bh))
  __jbd2_journal_remove_checkpoint(jh)
   if (buffer_write_io_error(bh)) // false
                             >> bh IO error occurs <<
 jbd2_cleanup_journal_tail
  __jbd2_update_log_tail
   jbd2_write_superblock
   // The bh won't be replayed in next mount.
, which could corrupt the ext4 image, fetch a reproducer in [Link].

Since writeback process clears buffer dirty after locking buffer head,
we can fix it by try locking buffer and check dirtiness while buffer is
locked, the buffer head can be removed if it is neither dirty nor locked.

2ecab4882c r8169: revert 2ab19de62d ("r8169: remove ASPM restrictions now that ASPM is disabled during NAPI poll")
commit cf2ffdea08 upstream.

There have been reports that on a number of systems this change breaks
network connectivity. Therefore effectively revert it. Mainly affected
seem to be systems where BIOS denies ASPM access to OS.
Due to later changes we can't do a direct revert.

979f8de763 drm/amd: Align SMU11 SMU_MSG_OverridePcieParameters implementation with SMU13
commit e701156ccc upstream.

SMU13 overrides dynamic PCIe lane width and dynamic speed by when on
certain hosts. commit 38e4ced804 ("drm/amd/pm: conditionally disable
pcie lane switching for some sienna_cichlid SKUs") worked around this
issue by setting up certain SKUs to set up certain limits, but the same
fundamental problem with those hosts affects all SMU11 implmentations
as well, so align the SMU11 and SMU13 driver handling.

This helper is used for checking if the connected host supports
the feature, it can be moved into generic code to be used by other
smu implementations as well.
