Some sky2 chips fire IRQ after S3, before the driver is fully resumed:

This is likely a platform bug that device isn't fully quiesced during
S3. Use MSI-X, maskable MSI or INTx can prevent this issue from
happening.
Since MSI-X and maskable MSI are not supported by this device, fallback
to use INTx on affected platforms.

This patchset includes a fix [patch 01] to the devlink health state update, in

Once channels were successfully opened, update tx reporter health state to
healthy. This is needed for the following scenario:
- SQ has an un-recovered error reported to the devlink health, resulting tx
reporter state to be error.
- Current channels (including this SQ) are closed
- New channels are opened
After that flow, the original error was "solved", and tx reporter state
should be healthy. However, as it was resolved as a side effect, and not
via tx reporter recover method, driver needs to inform devlink health
about it.

Similar to commit 44f49dd8b5 ("ipmr: fix possible race resulting from
improper usage of IP_INC_STATS_BH() in preemptible context."), we cannot
assume preemption is disabled when incrementing the counter and
accessing a per-CPU variable.
Preemption can be enabled when we add a route in process context that
corresponds to packets stored in the unresolved queue, which are then
forwarded using this route [1].
Fix this by using IP6_INC_STATS() which takes care of disabling
preemption on architectures where it is needed.

Every in-kernel use of this function defined it to KERNEL_DS (either as
an actual define, or as an inline function). It's an entirely
historical artifact, and long long long ago used to actually read the
segment selector valueof '%ds' on x86.
Which in the kernel is always KERNEL_DS.
Inspired by a patch from Jann Horn that just did this for a very small
subset of users (the ones in fs/), along with Al who suggested a script.
I then just took it to the logical extreme and removed all the remaining
gunk.
Roughly scripted with
git grep -l '(get_ds())' -- :^tools/ | xargs sed -i 's/(get_ds())/(KERNEL_DS)/'
git grep -lw 'get_ds' -- :^tools/ | xargs sed -i '/^#define get_ds()/d'
plus manual fixups to remove a few unusual usage patterns, the couple of
inline function cases and to fix up a comment that had become stale.
The 'get_ds()' function remains in an x86 kvm selftest, since in user
space it actually does something relevant.

Al Viro root-caused a race where the IOCB_CMD_POLL handling of
fget/fput() could cause us to access the file pointer after it had
already been freed:
"In more details - normally IOCB_CMD_POLL handling looks so:
1) io_submit(2) allocates aio_kiocb instance and passes it to
aio_poll()
2) aio_poll() resolves the descriptor to struct file by req->file =
fget(iocb->aio_fildes)
3) aio_poll() sets ->woken to false and raises ->ki_refcnt of that
aio_kiocb to 2 (bumps by 1, that is).
4) aio_poll() calls vfs_poll(). After sanity checks (basically,
"poll_wait() had been called and only once") it locks the queue.
That's what the extra reference to iocb had been for - we know we
can safely access it.
5) With queue locked, we check if ->woken has already been set to
true (by aio_poll_wake()) and, if it had been, we unlock the
queue, drop a reference to aio_kiocb and bugger off - at that
point it's a responsibility to aio_poll_wake() and the stuff
called/scheduled by it. That code will drop the reference to file
in req->file, along with the other reference to our aio_kiocb.
6) otherwise, we see whether we need to wait. If we do, we unlock the
queue, drop one reference to aio_kiocb and go away - eventual
wakeup (or cancel) will deal with the reference to file and with
the other reference to aio_kiocb
7) otherwise we remove ourselves from waitqueue (still under the
queue lock), so that wakeup won't get us. No async activity will
be happening, so we can safely drop req->file and iocb ourselves.
If wakeup happens while we are in vfs_poll(), we are fine - aio_kiocb
won't get freed under us, so we can do all the checks and locking
safely. And we don't touch ->file if we detect that case.
However, vfs_poll() most certainly *does* touch the file it had been
given. So wakeup coming while we are still in ->poll() might end up
doing fput() on that file. That case is not too rare, and usually we
are saved by the still present reference from descriptor table - that
fput() is not the final one.
But if another thread closes that descriptor right after our fget()
and wakeup does happen before ->poll() returns, we are in trouble -
final fput() done while we are in the middle of a method:
Al also wrote a patch to take an extra reference to the file descriptor
to fix this, but I instead suggested we just streamline the whole file
pointer handling by submit_io() so that the generic aio submission code
simply keeps the file pointer around until the aio has completed.

knob where monitoring tools can make use of this to efficiently
determine the average cost of programs, from Alexei.
4) Split up BPF selftest's test_progs similarly as we already

improvements, from Andrii.
6) Various BPF sample cleanups and migration to libbpf in order
to further isolate the old sample loader code (so we can get

This adds a warning (once) for any kernel dereference that has a user
exception handler, but accesses a non-canonical address. It basically
is a simpler - and more limited - version of commit 9da3f2b740
("x86/fault: BUG() when uaccess helpers fault on kernel addresses") that
got reverted.
Note that unlike that original commit, this only causes a warning,
because there are real situations where we currently can do this
(notably speculative argument fetching for uprobes etc). Also, unlike
that original commit, this _only_ triggers for #GP accesses, so the
cases of valid kernel pointers that cross into a non-mapped page aren't
affected.
The intent of this is two-fold:
- the uprobe/tracing accesses really do need to be more careful. In
particular, from a portability standpoint it's just wrong to think
that "a pointer is a pointer", and use the same logic for any random
pointer value you find on the stack. It may _work_ on x86-64, but it
doesn't necessarily work on other architectures (where the same
pointer value can be either a kernel pointer _or_ a user pointer, and
you really need to be much more careful in how you try to access it)
The warning can hopefully end up being a reminder that just any
random pointer access won't do.
- Kees in particular wanted a way to actually report invalid uses of
wild pointers to user space accessors, instead of just silently
failing them. Automated fuzzers want a way to get reports if the
kernel ever uses invalid values that the fuzzer fed it.
The non-canonical address range is a fair chunk of the address space,
and with this you can teach syzkaller to feed in invalid pointer
values and find cases where we do not properly validate user
addresses (possibly due to bad uses of "set_fs()").

The minimal driver is chip independent and uses I2C bus for chip access.
Its purpose is to support chassis management on systems equipped with

Patches #1-#3 add ethtool support to the minimal driver so that QSFP/SFP
module info could be retrieved by the driver. This is done by exposing a
dummy netdev for each front panel port and implementing the required
ethtool operations.
Patches #4-#8 add resource query support. This allows the driver to

number of ports). It is required on systems where the maximum number of
ports is larger than the hard coded default (64).

Quectel EG12 (module)/EM12 (M.2 card) is a Cat. 12 LTE modem. The modem
behaves in the same way as the EP06, so the "set DTR"-quirk must be
applied and the diagnostic-interface check performed. Since the
diagnostic-check now applies to more modems, I have renamed the function
from quectel_ep06_diag_detected() to quectel_diag_detected().

Make logging of an ethernet address more consistent with
the rest of the kernel.
Miscellanea:
The %02hx use also did not quite match the u8 definition
of addr though that did not actually matter given normal
integer promotion rules.
