linux-toradex.git/net/mac80211/scan.c, branch v3.7.4 Linux kernel for Apalis and Colibri modules mac80211: fix ibss scanning 2013-01-17T16:46:36+00:00 Stanislaw Gruszka sgruszka@redhat.com 2012-12-11T09:48:23+00:00 1cf18948040a40fa4497e40bcde2ffa8d6b1196e commit 34bcf71502413f8903ade93746f2d0f04b937a78 upstream. Do not scan on no-IBSS and disabled channels in IBSS mode. Doing this can trigger Microcode errors on iwlwifi and iwlegacy drivers. Also rename ieee80211_request_internal_scan() function since it is only used in IBSS mode and simplify calling it from ieee80211_sta_find_ibss().

Pass the channel to the ieee80211_send_probe_req() function so it can be used in the different scenarios. The scan code continues to pass the current channel, of course.

mac80211: don't clear sched_scan_sdata on sched scan stop request 2012-07-30T07:14:36+00:00 Eliad Peller eliad@wizery.com 2012-07-29T13:25:10+00:00 ba846a502c6b3c0ff047861c891fd1afeed6e435 ieee80211_request_sched_scan_stop() cleared local->sched_scan_sdata. However, sched_scan_sdata should be cleared only after the driver calls ieee80211_sched_scan_stopped() (like with normal hw scan). Clearing sched_scan_sdata too early caused ieee80211_sched_scan_stopped_work to exit prematurely without properly cleaning all the sched scan resources and without calling cfg80211_sched_scan_stopped (so userspace wasn't notified about sched scan completion).
