mac80211: fix rx->key NULL dereference during mic failure

2011-06-27T18:45:25+00:00

Sometimes when reporting a MIC failure rx->key may be unset. This
code path is hit when receiving a packet meant for a multicast
address, and decryption is performed in HW.

Fortunately, the failing key_idx is not used for anything up to
(and including) usermode, so we allow ourselves to drop it on the
way up when a key cannot be retrieved.

mac80211: fix IBSS teardown race

2011-06-08T18:19:05+00:00

Ignacy reports that sometimes after leaving an IBSS
joining a new one didn't work because there still
were stations on the list. He fixed it by flushing
stations when attempting to join a new IBSS, but
this shouldn't be happening in the first case. When
I looked into it I saw a race condition in teardown
that could cause stations to be added after flush,
and thus cause this situation. Ignacy confirms that
after applying my patch he hasn't seen this happen
again.

reason, and about whether this patch actually serves its intended
purpose at all.

mac80211: call dev_alloc_name before copying name to sdata

2011-06-03T18:22:06+00:00

This partially reverts 1c5cae815d19ffe02bdfda1260949ef2b1806171, because
the netdev name is copied into sdata->name, which is used for debugging
messages, for example. Otherwise, we get messages like this:

mac80211: clear local->ps_data on disassoc

2011-05-27T16:53:46+00:00

local->ps_data wasn't cleared on disassociation, which
(in some corner cases) caused reconnections to enter
psm before association completed.

mac80211: stop queues before rate control updation

2011-05-26T19:43:33+00:00

Stop tx queues before updating rate control to ensure
proper rate selection. Otherwise packets can be transmitted
in 40 Mhz whereas hw is configured in HT20.
