2013-12-05cfg80211: don't "leak" uncompleted scansEliad Peller
___cfg80211_scan_done() can be called in some cases (e.g. on NETDEV_DOWN) before the low level driver notified scan completion (which is indicated by passing leak=true). Clearing rdev->scan_req in this case is buggy, as scan_done_wk might have already being queued/running (and can't be flushed as it takes rtnl()). If a new scan will be requested at this stage, the scan_done_wk will try freeing it (instead of the previous scan), and this will later result in a use after free. Simply remove the "leak" option, and replace it with a standard WARN_ON. An example backtrace after such crash: Unable to handle kernel paging request at virtual address fffffee5 pgd = c0004000 [fffffee5] *pgd=9fdf6821, *pte=00000000, *ppte=00000000 Internal error: Oops: 17 [#1] SMP ARM PC is at cfg80211_scan_done+0x28/0xc4 [cfg80211] LR is at __ieee80211_scan_completed+0xe4/0x2dc [mac80211] [<bf0077b0>] (cfg80211_scan_done+0x28/0xc4 [cfg80211]) [<bf0973d4>] (__ieee80211_scan_completed+0xe4/0x2dc [mac80211]) [<bf0982cc>] (ieee80211_scan_work+0x94/0x4f0 [mac80211]) [<c005fd10>] (process_one_work+0x1b0/0x4a8) [<c0060404>] (worker_thread+0x138/0x37c) [<c0066d70>] (kthread+0xa4/0xb0) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2013-12-03nl80211: vendor command supportJohannes Berg
Add support for vendor-specific commands to nl80211. This is intended to be used for really vendor-specific functionality that can't be implemented in a generic fashion for any reason. It's *NOT* intended to be used for any normal/generic feature or any optimisations that could be implemented across drivers. Currently, only vendor commands (with replies) are supported, no dump operations or vendor-specific notifications.

2013-11-25cfg80211: enforce disabling channels by custom or strict settingsLuis R. Rodriguez
If a custom regulatory domain is passed and if a rule for a channel indicates it should be disabled that channel should always remain disabled as per its documentation and design. Likewise if WIPHY_FLAG_STRICT_REGULATORY flag is set and a regulatory_hint() is issued if a channel is disabled that channel should remain disabled. Without this change only drivers that set the _orig flags appropriately on their own would ensure disallowed channels remaind disabled. This helps drivers save code by relying on the APIS provided to entrust channels that should not be enabled be respected by only having to use wiphy_apply_custom_regulatory() or regulatory_hint() with the WIPHY_FLAG_STRICT_REGULATORY set. If wiphy_apply_custom_regulatory() is used together with WIPHY_FLAG_STRICT_REGULATORY and a regulatory_hint() issued later, the incoming regulatory domain can override previously set _orig parameters from the initial custom regulatory setting.
