wifi: cfg80211: fully move wiphy work to unbound workqueue

2024-05-29T13:23:33+00:00

Previously I had moved the wiphy work to the unbound
system workqueue, but missed that when it restarts and
during resume it was still using the normal system
workqueue. Fix that.

wifi: nl80211: clean up coalescing rule handling

2024-05-29T08:38:53+00:00

There's no need to allocate a tiny struct and then
an array again, just allocate the two together and
use __counted_by(). Also unify the freeing.

wifi: cfg80211: add tracing for wiphy work

2024-05-23T08:21:22+00:00

Add trace events to trace when wiphy works are queued (or
delayed ones scheduled), and other APIs are called. Also
add an event when the worker starts, before acquiring the
mutex, to be able to see potential delays due to locking.

wifi: cfg80211: fix wiphy delayed work queueing

2024-01-26T09:43:32+00:00

When a wiphy work is queued with timer, and then again
without a delay, it's started immediately but *also*
started again after the timer expires. This can lead,
for example, to warnings in mac80211's offchannel code
as reported by Jouni. Running the same work twice isn't
expected, of course. Fix this by deleting the timer at
this point, when queuing immediately due to delay=0.

wifi: cfg80211: hold wiphy mutex for send_interface

2023-11-24T17:30:48+00:00

Given all the locking rework in mac80211, we pretty much
need to get into the driver with the wiphy mutex held in
all callbacks. This is already mostly the case, but as
Johan reported, in the get_txpower it may not be true.

Lock the wiphy mutex around nl80211_send_iface(), then
is also around callers of nl80211_notify_iface(). This
is easy to do, fixes the problem, and aligns the locking
between various calls to it in different parts of the
code of cfg80211.

wifi: cfg80211: use system_unbound_wq for wiphy work

2023-10-11T14:36:12+00:00

Since wiphy work items can run pretty much arbitrary
code in the stack/driver, it can take longer to run
all of this, so we shouldn't be using system_wq via
schedule_work(). Also, we lock the wiphy (which is
the reason this exists), so use system_unbound_wq.

Resolve several conflicts, mostly between changes/fixes in
wireless and the locking rework in wireless-next. One of
the conflicts actually shows a bug in wireless that we'll
want to fix separately.
