* mac80211: fix sta lookup with AP VLAN interfaces and injected framesFelix Fietkau2010-02-01
| | | | | | | | | | | | When injecting frames, mac80211 currently looks for the first AP interface that matches the source address of the injected frame. This breaks when such a frame is directed at a STA that has been moved to a VLAN. This patch fixes it by using sta_info_get_bss instead of sta_info_get, which also finds stations belonging to a VLAN interface of the same BSS as the AP interface.

* mac80211: fix monitor mode tx radiotap header handlingFelix Fietkau2010-02-01
| | | | | | | | | | | | | | When an injected frame gets buffered for a powersave STA or filtered and retransmitted, mac80211 attempts to parse the radiotap header again, which doesn't work because it's gone at that point. This patch adds a new flag for checking the availability of a radiotap header, so that it only attempts to parse it once, reusing the tx info on the next call to ieee80211_tx(). This fixes severe issues with rekeying in AP mode. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Cc: stable@kernel.org Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: fix sta lookup for received action frames on an AP VLANFelix Fietkau2010-02-01
| | | | | | | | | | | | When looking for a matching interface, __ieee80211_rx_handle_packet loops over all active interfaces, looking for matching stations. Because AP VLAN interfaces are not processed as part of this loop, it needs to use sta_info_get_bss instead of sta_info_get in order to find a STA that has been moved to a VLAN. This fixes issues with aggregation setup/teardown. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* cfg80211: add regulatory hint disconnect supportLuis R. Rodriguez2010-02-01
| | | | | | | | | | | | | | | | This adds a new regulatory hint to be used when we know all devices have been disconnected and idle. This can happen when we suspend, for instance. When we disconnect we can no longer assume the same regulatory rules learned from a country IE or beacon hints are applicable so restore regulatory settings to an initial state. Since driver hints are cached on the wiphy that called the hint, those hints are not reproduced onto cfg80211 as the wiphy will respect its own wiphy->regd regardless. Signed-off-by: Luis R.

* cfg80211: avoid flushing the global workqueue for core reg hintsLuis R. Rodriguez2010-02-01
| | | | | | | | | | | | | | When cfg80211 starts it will send a core regulatory hint. This is sent to the global workqueue but we force processing of it by flushing the global workqueue. The flushing was done since cfg80211 needs last_request to always be populated. Avoid flushing the global workqueue by processing the work required immediately instead of putting it into a linked list and processing it after the flush. Signed-off-by: Luis R.

| | | | | | | | | | | | | Currently, the remain_on_channel work callback needs to track in its own data structure whether the work was just started or not.

Obviously, that broke software crypto. Maxim said so specifically, and Jochen probably uses some cipher that iwl3945 doesn't support in hardware, which might also explain that Maxim reports that even hw crypto is broken.
