2008-04-08Revert "mac80211: use a struct for bss->mesh_config"John W. Linville
This reverts commit 6c4711b4697d93424e4b1f76a9929ba844d714a5. That patch breaks mesh config comparison between beacons/probe reponses, so every beacon from a mesh network would be added as a new bss. Since the comparison has to be performed for every received beacon I believe it is best to save the mesh config in a format easy to compare, rather than do a bunch of unaligned accesses to compare field by field.

2008-03-06mac80211: fix sta_info mesh timer bugJohannes Berg
I noticed a bug I introduced when mesh is enabled: sta_info_destroy() will end up calling cancel_timer() on a timer that has never been initialized because the timer is only initialized in mesh_plink_alloc(), not in sta_info_alloc(). This patch moves the initialization of all mesh related fields into sta_info_alloc(), adds a bit of sanity checking to the cfg80211 handlers and sta_info_insert() and makes mesh_plink_alloc() a static helper function that is only used from the mesh plink code.

2008-03-06mac80211: split sta_info_addJohannes Berg
sta_info_add() has two functions: allocating a station info structure and inserting it into the hash table/list. Splitting these two functions allows allocating with GFP_KERNEL in many places instead of GFP_ATOMIC which is now required by the RCU protection. Additionally, in many places RCU protection is now no longer needed at all because between sta_info_alloc() and sta_info_insert() the caller owns the structure. This fixes a few race conditions with setting initial flags and similar, but not all (see comments in ieee80211_sta.c and cfg.c). More documentation on the existing races will be in a follow-up patch. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-03-06mac80211: RCU-ify STA info structure accessJohannes Berg
This makes access to the STA hash table/list use RCU to protect against freeing of items. However, it's not a true RCU, the copy step is missing: whenever somebody changes a STA item it is simply updated. This is an existing race condition that is now somewhat understandable. This patch also fixes the race key freeing vs. STA destruction by making sure that sta_info_destroy() is always called under RTNL and frees the key.
