no_llseek had been defined to NULL two years ago, in commit 868941b
("fs: remove no_llseek")
To quote that commit,
At -rc1 we'll need do a mechanical removal of no_llseek -
git grep -l -w no_llseek | grep -v porting.rst | while read i; do
sed -i '/\<no_llseek\>/d' $i
done
would do it.
Unfortunately, that hadn't been done. Linus, could you do that now, so
that we could finally put that thing to rest? All instances are of the
form
.llseek = no_llseek,
so it's obviously safe.
asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

There were crashes reported in this code, and the timer_shutdown()
warning in one of the previous patches indicates that the timeout
timer for the AP response (addba_resp_timer) is still armed while
we're stopping the aggregation session.
After a very long deliberation of the code, so far the only way I
could find that might cause this would be the following sequence:
- session start requested
- session start indicated to driver, but driver returns
IEEE80211_AMPDU_TX_START_DELAY_ADDBA
- session stop requested, sets HT_AGG_STATE_WANT_STOP
- session stop worker runs ___ieee80211_stop_tx_ba_session(),
sets HT_AGG_STATE_STOPPING
From here on, the order doesn't matter exactly, but:
1. driver calls ieee80211_start_tx_ba_cb_irqsafe(),
setting HT_AGG_STATE_START_CB
2. driver calls ieee80211_stop_tx_ba_cb_irqsafe(),
setting HT_AGG_STATE_STOP_CB
3. the worker will run ieee80211_start_tx_ba_cb() for
HT_AGG_STATE_START_CB
4. the worker will run ieee80211_stop_tx_ba_cb() for
HT_AGG_STATE_STOP_CB
(the order could also be 1./3./2./4.)
This will cause ieee80211_start_tx_ba_cb() to send out the AddBA
request frame to the AP and arm the timer, but we're already in
the middle of stopping and so the ieee80211_stop_tx_ba_cb() will
no longer assume it needs to stop anything.
Prevent this by checking for WANT_STOP/STOPPING in the start CB,
and warn if we're sending a frame on a stopping session.

There are cases where keeping sdata locked for an operation. Add a
variant that does not take sdata lock to permit these usecases.

Doing this simplifies the code somewhat, as iteration over the
nontransmitted BSSs is not required anymore. Also, mac80211 should
not be iterating over the nontrans_list as it should only be accessed
while the bss_lock is held.
It also simplifies parsing of the IEs somewhat, as cfg80211 already
extracts the IEs and passes them to the callback.
Note that the only user left requiring parsing a specific BSS is the
association code if a beacon is required by the hardware.

There are some locking changes that will later otherwise
cause conflicts, so merge wireless into wireless-next to
avoid those.

The channel switch parsing code would simply return if a scan is
in-progress. Supposedly, this was because channel switch announcements
from other APs should be ignored.
For the beacon case, the function is already only called if we are
associated with the sender. For the action frame cases, add the
appropriate check whether the frame is coming from the AP we are
associated with. Finally, drop the scanning check from
ieee80211_sta_process_chanswitch.
