cfg80211: do not replace BSS structs

2009-04-17T19:27:13+00:00

Instead, allocate extra IE memory if necessary. Normally,
this isn't even necessary since there's enough space.

This is a better way of correcting the "held BSS can
disappear" issue, but also a lot more code. It is also
necessary for proper auth/assoc BSS handling in the
future.

cfg80211: fix locking in nl80211_set_wiphy

2009-03-28T00:13:20+00:00

Luis reports that there's a circular locking dependency;
this is because cfg80211_dev_rename() will acquire the
cfg80211_mutex while the device mutex is held, while
this normally is done the other way around. The solution
is to open-code the device-getting in nl80211_set_wiphy
and require holding the mutex around cfg80211_dev_rename
rather than acquiring it within.

Also fix a bug -- rtnl locking is expected by drivers so
we need to provide it.

cfg80211: add feature to hold bss

2009-03-28T00:13:13+00:00

In beacon filtering there needs to be a way to not expire the BSS even
when no beacons are received. Add an interface to cfg80211 to hold
BSS and make sure that it's not expired.

cfg80211: move enum reg_set_by to nl80211.h

2009-03-16T22:09:40+00:00

We do this so we can later inform userspace who set the
regulatory domain and provide details of the request.

nl80211: Avoid AP mode BUG_ON hang with invalid lock assert

2009-02-27T19:53:04+00:00

"cfg80211: add assert_cfg80211_lock() to ensure proper protection"
added assert_cfg80211_lock() calls into various places. At least
one of them, nl80211_send_wiphy(), should not have been there. That
triggers the BUG_ON in assert_cfg80211_lock() and pretty much kills
the kernel whenever someone runs hostapd.. Remove that call and make
assert_cfg80211_lock() use WARN_ON instead of BUG_ON to be a bit more
friendly to users.

cfg80211: make regulatory_request use wiphy_idx instead of wiphy

2009-02-27T19:52:56+00:00

We do this so later on we can move the pending requests onto a
workqueue. By using the wiphy_idx instead of the wiphy we can
later easily check if the wiphy has disappeared or not.

cfg80211: rename cfg80211_drv_mutex to cfg80211_mutex

2009-02-27T19:52:55+00:00

cfg80211_drv_mutex is protecting more than the driver list,
this renames it and documents what its currently supposed to
protect.

This will later be used by others, for now make use of it in
cfg80211_drv_by_wiphy_idx() to return early if an invalid
