Using RTEXT_FILTER_SKIP_STATS is incorrectly skipping non-stats IPv6
netlink attributes on link dump. This causes issues on userspace tools,
e.g iproute2 is not rendering address generation mode as it should due
to missing netlink attribute.
Move the filling of IFLA_INET6_STATS and IFLA_INET6_ICMP6STATS to a
helper function guarded by a flag check to avoid hitting the same
situation in the future.

When queue is being reset, callbacks of mgmt_ops are called by
netdev_nl_bind_rx_doit().
The netdev_nl_bind_rx_doit() first acquires netdev_lock() and then calls
callbacks.
So, mgmt_ops callbacks should not acquire netdev_lock() internaly.
The bnxt_queue_{start | stop}() calls napi_{enable | disable}() but they
internally acquire netdev_lock().
So, deadlock occurs.
To avoid deadlock, napi_{enable | disable}_locked() should be used
instead.

I can not reproduce it on my machines, but judging by "Ip6OutNoRoutes"
there is no route to the local_addr (::1).
Looking at the kernel code, I see that kernel does add link-local
address automatically in init_loopback(), but that is called from
ipv6 notifier block. So, in turn the userspace that brought up
the loopback interface may see rtnetlink ACK earlier than
addrconf_notify() does it's job (at least, on a slow VM such as netdev).
Probably, for ipv4 it's the same, judging by inetdev_event().
The fix is quite simple: set the link-local route straight after
bringing the loopback interface. That will make it synchronous.

Pull tracing fixes from Steven Rostedt:
- Fix build error when CONFIG_PROBE_EVENTS_BTF_ARGS is not enabled
The tracing of arguments in the function tracer depends on some
functions that are only defined when PROBE_EVENTS_BTF_ARGS is

configs as the function argument tracing requires. Just have the
function argument tracing depend on PROBE_EVENTS_BTF_ARGS.
- Free module_delta for persistent ring buffer instance
When an instance holds the persistent ring buffer, it allocates a
helper array to hold the deltas between where modules are loaded on
the last boot and the current boot. This array needs to be freed when
the instance is freed.
- Add cond_resched() to loop in ftrace_graph_set_hash()
The hash functions in ftrace loop over every function that can be
enabled by ftrace. This can be 50,000 functions or more. This loop is
known to trigger soft lockup warnings and requires a cond_resched().
The loop in ftrace_graph_set_hash() was missing it.
- Fix the event format verifier to include "%*p.." arguments
To prevent events from dereferencing stale pointers that can happen
if a trace event uses a dereferece pointer to something that was not
copied into the ring buffer and can be freed by the time the trace is
read, a verifier is called. At boot or module load, the verifier
scans the print format string for pointers that can be dereferenced
and it checks the arguments to make sure they do not contain
something that can be freed. The "%*p" was not handled, which would
add another argument and cause the verifier to not only not verify
this pointer, but it will look at the wrong argument for every
pointer after that.
- Fix mcount sorttable building for different endian type target
When modifying the ELF file to sort the mcount_loc table in the
sorttable.c code, the endianess of the file and the host is used to
determine if the bytes need to be swapped when calculations are done.
A change was made to the sorting of the mcount_loc that read the
values from the ELF file into an array and the swap happened on the
filling of the array. But one of the calculations of the array still
did the swap when it did not need to. This caused building on a
little endian machine for a big endian target to not find the mcount
function in the 'nm' table and it zeroed it out, causing there to be
no functions available to trace.
- Add goto out_unlock jump to rv_register_monitor() on error path
One of the error paths in rv_register_monitor() just returned the
error when it should have jumped to the out_unlock label to release
the mutex.

If we crash when the journal pin fifo is completely full - i.e. we're
at the maximum number of dirty journal entries - that may put us in a
sticky situation in recovery, as journal replay will need to be able to
open new journal entries in order to get going.
bch2_fs_journal_start() already had provisions for resizing the journal
pin fifo if needed, but it needs a fudge factor to ensure there's room
for journal replay.

Codepaths that create entries in the snapshots btree currently call
bch2_mark_snapshot(), which updates the in-memory snapshot table, before
transaction commit.
This is because bch2_mark_snapshot() is an atomic trigger, run with
btree write locks held, and isn't allowed to fail - but it might need to
reallocate the table, hence we call it early when we're still allowed to
fail.
This is generally harmless - if we fail, we'll have left an entry in the
snapshots table around, but nothing will reference it and it'll get
overwritten if reused by another transaction.
But check_snapshot_exists(), which reconstructs snapshots when the
snapshots btree has been corrupted or lost, was erronously rechecking if
the snapshot exists inside the transaction commit loop - so on
transaction restart (in this case mem_realloced), the second iteration
would return without repairing.
This code needs some cleanup: splitting out a "maybe realloc snapshots
table" helper would have avoided this, that will be in the next patch.

The ufs device JEDEC specification version 4.1 adds support for the
device level exception events. To support this new device level
exception feature, expose two new sysfs nodes below to provide the user
space access to the device level exception information.
/sys/bus/platform/drivers/ufshcd/*/device_lvl_exception_count
/sys/bus/platform/drivers/ufshcd/*/device_lvl_exception_id
The device_lvl_exception_count sysfs node reports the number of device
level exceptions that have occurred since the last time this variable is
reset. Writing a value of 0 will reset it. The device_lvl_exception_id
reports the exception ID which is the qDeviceLevelExceptionID attribute
of the device JEDEC specifications version 4.1 and later. The user space
application can query these sysfs nodes to get more information about
the device level exception.

The smartpqi driver checks the reset_devices variable to determine
whether special adjustments need to be made for kdump. This has the
effect that after a regular kexec reboot, some driver parameters such as
max_transfer_size are much lower than usual. More importantly, kexec
reboot tests have revealed memory corruption caused by the driver log
being written to system memory after a kexec.
Fix this by testing is_kdump_kernel() rather than reset_devices where
appropriate.

Hi folks,
This series fixes several stability issues with the upstream ufs-exynos
driver, specifically for the gs101 SoC found in Pixel 6.
The main fix is regarding the IO cache coherency setting and ensuring
that it is correctly applied depending on if the dma-coherent property
is specified in device tree. This fixes the UFS stability issues on gs101
and I would imagine will also fix issues on exynosauto platform that
seems to have similar iocc shareability bits.
Additionally the phy reference counting is fixed which allows module
load/unload to work reliably and keeps the phy state machine in sync
with the controller glue driver.

Peter

Eliminate a useless task_work on execve by moving the call to
rseq_set_notify_resume() from sched_mm_cid_after_execve() to the error
path of bprm_execve().
The call to rseq_set_notify_resume() from sched_mm_cid_after_execve() is
pointless in the success case, because rseq_execve() will clear the rseq
pointer before returning to userspace.
sched_mm_cid_after_execve() is called from both the success and error
paths of bprm_execve(). The call to rseq_set_notify_resume() is needed
on error because the mm_cid may have changed.
Also move the rseq_execve() to right after sched_mm_cid_after_execve()
in bprm_execve().

counters, in dst_release too.

In the EIP93 HASH functions, the eip93_put_descriptor is called without
acquiring lock. This is problematic when multiple thread execute hash
operations.
Correctly acquire ring write lock on calling eip93_put_descriptor to
prevent concurrent access and mess with the ring pointers.
