genirq: Synchronize only with single thread on free_irq()
When pciehp is converted to threaded IRQ handling, removal of unplugged
devices below a PCIe hotplug port happens synchronously in the IRQ thread.
Removal of devices typically entails a call to free_irq() by their drivers.
If those devices share their IRQ with the hotplug port, __free_irq()
deadlocks because it calls synchronize_irq() to wait for all hard IRQ
handlers as well as all threads sharing the IRQ to finish.
Actually it's sufficient to wait only for the IRQ thread of the removed
device, so call synchronize_hardirq() to wait for all hard IRQ handlers to
finish, but no longer for any threads. Compensate by rearranging the
control flow in irq_wait_for_interrupt() such that the device's thread is
allowed to run one last time after kthread_stop() has been called.
kthread_stop() blocks until the IRQ thread has completed. On completion
the IRQ thread clears its oneshot thread_mask bit. This is safe because
__free_irq() holds the request_mutex, thereby preventing __setup_irq() from
handing out the same oneshot thread_mask bit to a newly requested action.
Stack trace for posterity:

genirq: Update code comments wrt recycled thread_mask
Previously a race existed between __free_irq() and __setup_irq() wherein
the thread_mask of a just removed action could be handed out to a newly
added action and the freed irq thread would then tread on the oneshot
mask bit of the newly added irq thread in irq_finalize_oneshot():
time
| __free_irq()
| raw_spin_lock_irqsave(&desc->lock, flags);
| <remove action from linked list>
| raw_spin_unlock_irqrestore(&desc->lock, flags);
|
| __setup_irq()
| raw_spin_lock_irqsave(&desc->lock, flags);
| <traverse linked list to determine oneshot mask bit>
| raw_spin_unlock_irqrestore(&desc->lock, flags);
|
| irq_thread() of freed irq (__free_irq() waits in synchronize_irq())
| irq_thread_fn()
| irq_finalize_oneshot()
| raw_spin_lock_irq(&desc->lock);
| desc->threads_oneshot &= ~action->thread_mask;
| raw_spin_unlock_irq(&desc->lock);
v
The race was known at least since 2012 when it was documented in a code
comment by commit
e04268b0effc ("genirq: Remove paranoid warnons and bogus
fixups"). The race itself is harmless as nothing touches any of the
potentially freed data after synchronize_irq().
In 2017 the race was close by commit
9114014cf4e6 ("genirq: Add mutex to
irq desc to serialize request/free_irq()"), apparently inadvertantly so
because the race is neither mentioned in the commit message nor was the
code comment updated. Make up for that.

length, but forgot to count any data pages in the request.

In addition, do some code refactoring by exporting smb2_rqst_len() to

This happened through fault injection where aead_req allocation in
tls_do_encryption() eventually failed and we returned -ENOMEM from
the function. Turns out that the use-after-free is triggered from
tls_sw_sendmsg() in the second tls_push_record(). The error then
triggers a jump to waiting for memory in sk_stream_wait_memory()
resp. returning immediately in case of MSG_DONTWAIT. What follows is
the trim_both_sgl(sk, orig_size), which drops elements from the sg
list added via tls_sw_sendmsg(). Now the use-after-free gets triggered
when the socket is being closed, where tls_sk_proto_close() callback
is invoked. The tls_complete_pending_work() will figure that there's
a pending closed tls record to be flushed and thus calls into the
tls_push_pending_closed_record() from there. ctx->push_pending_record()
is called from the latter, which is the tls_sw_push_pending_record()
from sw path. This again calls into tls_push_record(). And here the
tls_fill_prepend() will panic since the buffer address has been freed
earlier via trim_both_sgl(). One way to fix it is to move the aead
request allocation out of tls_do_encryption() early into tls_push_record().
This means we don't prep the tls header and advance state to the
TLS_PENDING_CLOSED_RECORD before allocation which could potentially
fail happened. That fixes the issue on my side.

stmmac: added support for 802.1ad vlan stripping
stmmac reception handler calls stmmac_rx_vlan() to strip the vlan before
calling napi_gro_receive().
The function assumes VLAN tagged frames are always tagged with
802.1Q protocol, and assigns ETH_P_8021Q to the skb by hard-coding
the parameter on call to __vlan_hwaccel_put_tag() .
This causes packets not to be passed to the VLAN slave if it was created
with 802.1AD protocol
(ip link add link eth0 eth0.100 type vlan proto 802.1ad id 100).
This fix passes the protocol from the VLAN header into
__vlan_hwaccel_put_tag() instead of using the hard-coded value of
ETH_P_8021Q.

afs: Optimise callback breaking by not repeating volume lookup
At the moment, afs_break_callbacks calls afs_break_one_callback() for each
separate FID it was given, and the latter looks up the volume individually
for each one.
However, this is inefficient if two or more FIDs have the same vid as we
could reuse the volume. This is complicated by cell aliasing whereby we
may have multiple cells sharing a volume and can therefore have multiple
callback interests for any particular volume ID.
At the moment afs_break_one_callback() scans the entire list of volumes
we're getting from a server and breaks the appropriate callback in every
matching volume, regardless of cell. This scan is done for every FID.
Optimise callback breaking by the following means:
(1) Sort the FID list by vid so that all FIDs belonging to the same volume
are clumped together.
This is done through the use of an indirection table as we cannot do
an insertion sort on the afs_callback_break array as we decode FIDs
into it as we subsequently also have to decode callback info into it
that corresponds by array index only.
We also don't really want to bubblesort afterwards if we can avoid it.
(2) Sort the server->cb_interests array by vid so that all the matching
volumes are grouped together. This permits the scan to stop after
finding a record that has a higher vid.
(3) When breaking FIDs, we try to keep server->cb_break_lock as long as
possible, caching the start point in the array for that volume group
as long as possible.
It might make sense to add another layer in that list and have a
refcounted volume ID anchor that has the matching interests attached
to it rather than being in the list. This would allow the lock to be
dropped without losing the cursor.

One possible fix is to hold the mutex all the way through bsg_get_device
instead of releasing it after bsg_class_device retrieval.

cfg80211: initialize sinfo in cfg80211_get_station
Most of the implementations behind cfg80211_get_station will not initialize
sinfo to zero before manipulating it. For example, the member "filled",
which indicates the filled in parts of this struct, is often only modified
by enabling certain bits in the bitfield while keeping the remaining bits
in their original state. A caller without a preinitialized sinfo.filled can
then no longer decide which parts of sinfo were filled in by
cfg80211_get_station (or actually the underlying implementations).
cfg80211_get_station must therefore take care that sinfo is initialized to
zero. Otherwise, the caller may tries to read information which was not
filled in and which must therefore also be considered uninitialized. In
batadv_v_elp_get_throughput's case, an invalid "random" expected throughput
may be stored for this neighbor and thus the B.A.T.M.A.N V algorithm may
switch to non-optimal neighbors for certain destinations.

nvme-fabrics: fix and refine state checks in __nvmf_check_ready
- make sure we only allow internally generates commands in any non-live

- only allow connect commands on non-live queues when actually in the

This fixes a regression where we could not shutdown a controller
