linux-toradex.git/net/mac80211/debugfs_sta.h, branch v3.0.44 Linux kernel for Apalis and Colibri modules mac80211: RCU-ify STA info structure access 2008-03-06T20:30:46+00:00 Johannes Berg johannes@sipsolutions.net 2008-02-25T15:27:46+00:00 d0709a65181beb787ef3f58cfe45536a2bb254c8 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.
