cfg80211: check wdev->netdev in connection work

2013-05-23T16:12:38+00:00

If a P2P-Device is present and another virtual interface triggers
the connection work, the system crash because it tries to check
if the P2P-Device's netdev (which doesn't exist) is up. Skip any
wdevs that have no netdev to fix this.

cfg80211: fix interface down/disconnect state handling

2013-05-16T20:38:08+00:00

When the interface goes down, there's no need to call
cfg80211_mlme_down() after __cfg80211_disconnect() as
the latter will call the former (if appropriate.)

Also, in __cfg80211_disconnect(), if the cfg80211 SME
isn't used, __cfg80211_disconnected() may still need
to be called (depending on the current state) so that
the SME state gets cleared.

cfg80211: sched_scan_mtx lock in cfg80211_conn_work()

2013-03-30T21:33:19+00:00

Introduced in f9f475292dbb0e7035fb6661d1524761ea0888d9
("cfg80211: always check for scan end on P2P device")

cfg80211_conn_scan() which requires sched_scan_mtx to be held can be called
from cfg80211_conn_work(). Without this we are hitting multiple warnings like
the following:

cfg80211: always check for scan end on P2P device

2013-03-24T10:15:58+00:00

If a P2P device wdev is removed while it has a scan, then the
scan completion might crash later as it is already freed by
that time. To avoid the crash always check the scan completion
when the P2P device is being removed for some reason. If the
driver already canceled it, don't want and free it, otherwise
warn and leak it to avoid later crashes.

In order to do this, locking needs to be changed away from the
rdev mutex (which can't always be guaranteed). For now, use
the sched_scan_mtx instead, I'll rename it to just scan_mtx in
a later patch.

cfg80211: fix potential connection work crash

2013-03-20T13:07:26+00:00

If wpa_supplicant and iw/iwconfig are used together, very
rarely the system crashes. It seems to be related to the
connection parameters not being set up, but it's not all
clear to me how this happens. In any case, checking that
the conn pointer exists here is probably a good idea.

cfg80211: refactor association parameters

2013-03-06T15:35:49+00:00

cfg80211_mlme_assoc() has grown far too many arguments,
make the caller build almost all of the driver struct
and pass that to the function instead.

cfg80211: add ability to override VHT capabilities

2013-03-06T15:35:47+00:00

For testing it's sometimes useful to be able to
override certain VHT capability advertisement,
add the ability to do that in cfg80211.

cfg80211: pass wiphy to cfg80211_ref_bss/put_bss

2013-02-11T17:44:52+00:00

This prepares for using the spinlock instead of krefs
which is needed in the next patch to track the refs
of combined BSSes correctly.
