blk-cgroup: Flush stats before releasing blkcg_gq

2023-06-21T14:02:19+00:00

commit 20cb1c2fb7568a6054c55defe044311397e01ddb upstream.

As noted by Michal, the blkg_iostat_set's in the lockless list hold
reference to blkg's to protect against their removal. Those blkg's
hold reference to blkcg. When a cgroup is being destroyed,
cgroup_rstat_flush() is only called at css_release_work_fn() which
is called when the blkcg reference count reaches 0. This circular
dependency will prevent blkcg and some blkgs from being freed after
they are made offline.

It is less a problem if the cgroup to be destroyed also has other
controllers like memory that will call cgroup_rstat_flush() which will
clean up the reference count. If block is the only controller that uses
rstat, these offline blkcg and blkgs may never be freed leaking more
and more memory over time.

To prevent this potential memory leak:

- flush blkcg per-cpu stats list in __blkg_release(), when no new stat
can be added

- add global blkg_stat_lock for covering concurrent parent blkg stat
update

- don't grab bio->bi_blkg reference when adding the stats into blkcg's
per-cpu stat list since all stats are guaranteed to be consumed before
releasing blkg instance, and grabbing blkg reference for stats was the
most fragile part of original patch

Based on Waiman's patch:

scsi: target: core: Fix error path in target_setup_session()

2023-06-21T14:02:18+00:00

commit 91271699228bfc66f1bc8abc0327169dc156d854 upstream.

In the error exits in target_setup_session(), if a branch is taken to
free_sess: transport_free_session() may call to target_free_cmd_counter()
and then fall through to call target_free_cmd_counter() a second time.
This can, and does, sometimes cause seg faults since the data field in
cmd_cnt->refcnt has been freed in the first call.

Fix this problem by simply returning after the call to
transport_free_session(). The second call is redundant for those cases.

arm64: dts: qcom: sm8550: Use the correct LLCC register scheme

2023-06-21T14:02:18+00:00

commit 661a4f089317c877aecd598fb70cd46510cc8d29 upstream.

During the ABI-breaking (for good reasons) conversion of the LLCC
register description, SM8550 was not taken into account, resulting
in LLCC being broken on any kernel containing the patch referenced
in the fixes tag.

Fix it by describing the regions properly.

current binutils (snapshot 2.40.50.20230611) the definitions in
 using "=" conflict with those:

Also delete the definition of gp, which isn't used anywhere.

afs: Fix vlserver probe RTT handling

2023-06-21T14:02:18+00:00

[ Upstream commit ba00b190670809c1a89326d80de96d714f6004f2 ]

In the same spirit as commit ca57f02295f1 ("afs: Fix fileserver probe
RTT handling"), don't rule out using a vlserver just because there
haven't been enough packets yet to calculate a real rtt.  Always set the
server's probe rtt from the estimate provided by rxrpc_kernel_get_srtt,
which is capped at 1 second.

This could lead to EDESTADDRREQ errors when accessing a cell for the
first time, even though the vl servers are known and have responded to a
probe.

selftests/ptp: Fix timestamp printf format for PTP_SYS_OFFSET

2023-06-21T14:02:18+00:00

[ Upstream commit 76a4c8b82938bc5020b67663db41f451684bf327 ]

Previously, timestamps were printed using "%lld.%u" which is incorrect
for nanosecond values lower than 100,000,000 as they're fractional
digits, therefore leading zeros are meaningful.

This patch changes the format strings to "%lld.%09u" in order to add
leading zeros to the nanosecond value.
