[ Upstream commit 30bcf4e824 ]
[BUG]
Since the introduction of btrfs bs < ps support, v1 cache was never on
the plan due to its hard coded PAGE_SIZE usage, and the future plan to
properly deprecate it.
However for bs < ps cases, even if 'nospace_cache,clear_cache' mount
option is specified, it's never respected and free space tree is always
enabled:
mkfs.btrfs -f -O ^bgt,fst $dev
mount $dev $mnt -o clear_cache,nospace_cache
umount $mnt
btrfs ins dump-super $dev
...
compat_ro_flags 0x3
( FREE_SPACE_TREE |
FREE_SPACE_TREE_VALID )
...
This means a different behavior compared to bs >= ps cases.
[CAUSE]
The forcing usage of v2 space cache is done inside
btrfs_set_free_space_cache_settings(), however it never checks if we're
even using space cache but always enabling v2 cache.
[FIX]
Instead unconditionally enable v2 cache, only forcing v2 cache if the
old v1 cache is required.
Now v2 space cache can be properly disabled on bs < ps cases:
mkfs.btrfs -f -O ^bgt,fst $dev
mount $dev $mnt -o clear_cache,nospace_cache
umount $mnt
btrfs ins dump-super $dev
...
compat_ro_flags 0x0
...

This issue specifically affects the ocelot_vsc7514.c frontend, which leaves

it uses the DSA framework which registers all ports.

[ Upstream commit 3128df6be1 ]
When using an 802.1ad bridge with vlan_tunnel, the C-VLAN tag is
incorrectly stripped from frames during egress processing.
br_handle_egress_vlan_tunnel() uses skb_vlan_pop() to remove the S-VLAN
from hwaccel before VXLAN encapsulation. However, skb_vlan_pop() also
moves any "next" VLAN from the payload into hwaccel:
/* move next vlan tag to hw accel tag */
__skb_vlan_pop(skb, &vlan_tci);
__vlan_hwaccel_put_tag(skb, vlan_proto, vlan_tci);
For QinQ frames where the C-VLAN sits in the payload, this moves it to
hwaccel where it gets lost during VXLAN encapsulation.
Fix by calling __vlan_hwaccel_clear_tag() directly, which clears only
the hwaccel S-VLAN and leaves the payload untouched.
This path is only taken when vlan_tunnel is enabled and tunnel_info
is configured, so 802.1Q bridges are unaffected.
Tested with 802.1ad bridge + VXLAN vlan_tunnel, verified C-VLAN
preserved in VXLAN payload via tcpdump.

[ Upstream commit 014a17deb4 ]
GPIO drivers with latch input support may miss short pulses on input
pins even when input latching is enabled. The generic interrupt logic in
the pca953x driver reports interrupts by comparing the current input
value against the previously sampled one and only signals an event when
a level change is observed between two reads.
For short pulses, the first edge is captured when the input register is
read, but if the signal returns to its previous level before the read,
the second edge is not observed. As a result, successive pulses can
produce identical input values at read time and no level change is
detected, causing interrupts to be missed. Below timing diagram shows
this situation where the top signal is the input pin level and the
bottom signal indicates the latched value.

PCAL variants provide an interrupt status register that records which
pins triggered an interrupt, but the status and input registers cannot
be read atomically. The interrupt status is only cleared when the input
port is read, and the input value must also be read to determine the
triggering edge. If another interrupt occurs on a different line after
the status register has been read but before the input register is
sampled, that event will not be reflected in the earlier status
snapshot, so relying solely on the interrupt status register is also
insufficient.
Support for input latching and interrupt status handling was previously
added by [1], but the interrupt status-based logic was reverted by [2]
due to these issues. This patch addresses the original problem by
combining both sources of information. Events indicated by the interrupt
status register are merged with events detected through the existing
level-change logic. As a result:
* short pulses, whose second edges are invisible, are detected via the
interrupt status register, and
* interrupts that occur between the status and input reads are still
caught by the generic level-change logic.
This significantly improves robustness on devices that signal interrupts
as short pulses, while avoiding the issues that led to the earlier
reversion. In practice, even if only the first edge of a pulse is
observable, the interrupt is reliably detected.
This fixes missed interrupts from an Ilitek touch controller with its
interrupt line connected to a PCAL6416A, where active-low pulses are
approximately 200 us long.

When evicting an inode the first thing we do is to setup tracing for it,
which implies fetching the root's id. But in btrfs_evict_inode() the
root might be NULL, as implied in the next check that we do in
btrfs_evict_inode().
Hence, we either should set the ->root_objectid to 0 in case the root is
NULL, or we move tracing setup after checking that the root is not
NULL. Setting the rootid to 0 at least gives us the possibility to trace
this call even in the case when the root is NULL, so that's the solution
taken here.

[BUG]
There is a bug that if a subvolume has multi-level parent qgroups, and
is able to do a quick inherit, only the direct parent qgroup got
updated:
mkfs.btrfs -f -O quota $dev
mount $dev $mnt
btrfs subv create $mnt/subv1
btrfs qgroup create 1/100 $mnt
btrfs qgroup create 2/100 $mnt
btrfs qgroup assign 1/100 2/100 $mnt
btrfs qgroup assign 0/256 1/100 $mnt
btrfs qgroup show -p --sync $mnt

2/100 16.00KiB 16.00KiB - <0 member qgroups>
# Note that 2/100 is not updated, and qgroup numbers are inconsistent
umount $mnt
[CAUSE]
If the snapshot source subvolume belongs to a parent qgroup, and the new
snapshot target is also added to the new same parent qgroup, we allow a
quick update without marking qgroup inconsistent.
But that quick update only update the parent qgroup, without checking if
there is any more parent qgroups.
[FIX]
Iterate through all parent qgroups during the quick inherit.

[ Upstream commit 7ee19a59a7 ]
qgroup_snapshot_quick_inherit() detects conditions where the snapshot
destination would land in the same parent qgroup as the snapshot source
subvolume. In this case we can avoid costly qgroup calculations and just
add the nodesize of the new snapshot to the parent.
However, in the case of squotas this is actually a double count, and
also an undercount for deeper qgroup nestings.
The following annotated script shows the issue:
btrfs quota enable --simple "$mnt"
# Create 2-level qgroup hierarchy
btrfs qgroup create 2/100 "$mnt" # Q2 (level 2)
btrfs qgroup create 1/100 "$mnt" # Q1 (level 1)
btrfs qgroup assign 1/100 2/100 "$mnt"
# Create base subvolume
btrfs subvolume create "$mnt/base" >/dev/null
base_id=$(btrfs subvolume show "$mnt/base" | grep 'Subvolume ID:' | awk '{print $3}')
# Create intermediate snapshot and add to Q1
btrfs subvolume snapshot "$mnt/base" "$mnt/intermediate" >/dev/null
inter_id=$(btrfs subvolume show "$mnt/intermediate" | grep 'Subvolume ID:' | awk '{print $3}')
btrfs qgroup assign "0/$inter_id" 1/100 "$mnt"
# Create working snapshot with --inherit (auto-adds to Q1)
# src=intermediate (in only Q1)
# dst=snap (inheriting only into Q1)
# This double counts the 16k nodesize of the snapshot in Q1, and
# undercounts it in Q2.
btrfs subvolume snapshot -i 1/100 "$mnt/intermediate" "$mnt/snap" >/dev/null
snap_id=$(btrfs subvolume show "$mnt/snap" | grep 'Subvolume ID:' | awk '{print $3}')
# Fully complete snapshot creation
sync
# Delete working snapshot
# Q1 and Q2 will lose the full snap usage
btrfs subvolume delete "$mnt/snap" >/dev/null
# Delete intermediate and remove from Q1
# Q1 and Q2 will lose the full intermediate usage
btrfs qgroup remove "0/$inter_id" 1/100 "$mnt"
btrfs subvolume delete "$mnt/intermediate" >/dev/null
# Q1 should be at 0, but still has 16k. Q2 is "correct" at 0 (for now...)
# Trigger cleaner, wait for deletions
mount -o remount,sync=1 "$mnt"
btrfs subvolume sync "$mnt" "$snap_id"
btrfs subvolume sync "$mnt" "$inter_id"
# Remove Q1 from Q2
# Frees 16k more from Q2, underflowing it to 16EiB
btrfs qgroup remove 1/100 2/100 "$mnt"
# And show the bad state:
btrfs qgroup show -pc "$mnt"

Fix this by simply not doing this quick inheritance with squotas.
I suspect that it is also wrong in normal qgroups to not recurse up the
qgroup tree in the quick inherit case, though other consistency checks
will likely fix it anyway.

[ Upstream commit b4bb6daf4a ]
When a W-LUN resume fails, its parent devices in the SCSI hierarchy,
including the scsi_target, may be runtime suspended. Subsequently, the
error handler in ufshcd_recover_pm_error() fails to set the W-LUN device
back to active because the parent target is not active. This results in
the following errors:
google-ufshcd 3c2d0000.ufs: ufshcd_err_handler started; HBA state eh_fatal; ...
ufs_device_wlun 0:0:0:49488: START_STOP failed for power mode: 1, result 40000
ufs_device_wlun 0:0:0:49488: ufshcd_wl_runtime_resume failed: -5
...
ufs_device_wlun 0:0:0:49488: runtime PM trying to activate child device 0:0:0:49488 but parent (target0:0:0) is not active
Address this by:
1. Ensuring the W-LUN's parent scsi_target is runtime resumed before
attempting to set the W-LUN to active within
ufshcd_recover_pm_error().
2. Explicitly checking for power.runtime_error on the HBA and W-LUN
devices before calling pm_runtime_set_active() to clear the error
state.
3. Adding pm_runtime_get_sync(hba->dev) in
ufshcd_err_handling_prepare() to ensure the HBA itself is active
during error recovery, even if a child device resume failed.
These changes ensure the device power states are managed correctly
during error recovery.

[ Upstream commit 2e47c3cc64 ]
We have observed an NFSv4 client receiving a LOCK reply with a status of
NFS4ERR_OLD_STATEID and subsequently retrying the LOCK request with an
earlier seqid value in the stateid. As this was for a new lockowner,
that would imply that nfs_set_open_stateid_locked() had updated the open
stateid seqid with an earlier value.
Looking at nfs_set_open_stateid_locked(), if the incoming seqid is out
of sequence, the task will sleep on the state->waitq for up to 5
seconds. If the task waits for the full 5 seconds, then after finishing
the wait it'll update the open stateid seqid with whatever value the
incoming seqid has. If there are multiple waiters in this scenario,
then the last one to perform said update may not be the one with the
highest seqid.
Add a check to ensure that the seqid can only be incremented, and add a
tracepoint to indicate when old seqids are skipped.

gup_pgd_range() is invoked with disabled interrupts and invokes
__kmap_local_page_prot() via pte_offset_map(), gup_p4d_range().
With HIGHPTE enabled, __kmap_local_page_prot() invokes kmap_high_get()
which uses a spinlock_t via lock_kmap_any(). This leads to an
sleeping-while-atomic error on PREEMPT_RT because spinlock_t becomes a
sleeping lock and must not be acquired in atomic context.
The loop in map_new_virtual() uses wait_queue_head_t for wake up which
also is using a spinlock_t.
Since HIGHPTE is rarely needed at all, turn it off for PREEMPT_RT
to allow the use of get_user_pages_fast().

commit c0fe2994f9 upstream.
Currently calc_target() clears t->paused if the request shouldn't be
paused anymore, but doesn't ever set t->paused even though it's able to
determine when the request should be paused. Setting t->paused is left
to __submit_request() which is fine for regular requests but doesn't
work for linger requests -- since __submit_request() doesn't operate
on linger requests, there is nowhere for lreq->t.paused to be set.
One consequence of this is that watches don't get reestablished on
paused -> unpaused transitions in cases where requests have been paused
long enough for the (paused) unwatch request to time out and for the
subsequent (re)watch request to enter the paused state. On top of the
watch not getting reestablished, rbd_reregister_watch() gets stuck with
rbd_dev->watch_mutex held:
rbd_register_watch
__rbd_register_watch
ceph_osdc_watch
linger_reg_commit_wait
It's waiting for lreq->reg_commit_wait to be completed, but for that to
happen the respective request needs to end up on need_resend_linger list
and be kicked when requests are unpaused. There is no chance for that
if the request in question is never marked paused in the first place.
The fact that rbd_dev->watch_mutex remains taken out forever then
prevents the image from getting unmapped -- "rbd unmap" would inevitably
hang in D state on an attempt to grab the mutex.

commit 11194b416e upstream.
When a fault occurs, the connection is abandoned, reestablished, and any
pending operations are retried. The OSD client tracks the progress of a
sparse-read reply using a separate state machine, largely independent of
the messenger's state.
If a connection is lost mid-payload or the sparse-read state machine
returns an error, the sparse-read state is not reset. The OSD client
will then interpret the beginning of a new reply as the continuation of
the old one. If this makes the sparse-read machinery enter a failure
state, it may never recover, producing loops like:
libceph: [0] got 0 extents
libceph: data len 142248331 != extent len 0
libceph: osd0 (1)...:6801 socket error on read
libceph: data len 142248331 != extent len 0
libceph: osd0 (1)...:6801 socket error on read
Therefore, reset the sparse-read state in osd_fault(), ensuring retries
start from a clean state.
