* b43: fix use-after-free rfkill bugStefano Brivio2008-01-16

* b43: Fix rxheader channel parsingMichael Buesch2008-01-09
| | | | | | | | | | | | This patch fixes the parsing of the RX data header channel field. The current code parses the header incorrectly and passes a wrong channel number and frequency for each frame to mac80211. The FIXMEs added by this patch don't matter for now as the code where they live won't get executed anyway. They will be fixed later.

* b43: Fix rfkill radio LEDLarry Finger2007-12-17
| | | | | | | | | | | | | | | | | | | | | | | | This fixes Bug #9414 Since addition of the rfkill callback, the LED associated with the off switch on the radio has not worked for several reasons: (1) Essential data in the rfkill structure were missing. (2) The rfkill structure was initialized after the LED initialization. (3) There was a minor memory leak if the radio LED structure was inited. Once the above problems were fixed, additional difficulties were noted: (4) The radio LED was in the wrong state at startup. (5) The radio switch had to be manipulated twice for each state change. (6) A circular mutex locking situation existed. (7) If rfkill-input is built as a module, it is not automatically loaded. This patch fixes all of the above.

* b43: properly request pcmcia IRQMichael Buesch2007-11-10
| | | | | | | | | | PCMCIA needs an additional step to request the IRQ. No need to add code to release the IRQ here, as that's done automatically in pcmcia_disable_device(). Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* b43: fix shared IRQ race conditionStefano Brivio2007-11-10
| | | | | | | | | | | Fix an IRQ race condition in b43. If we call b43_stop_wireless_core(), it will set the status of the device to INITIALIZED and the IRQ handler won't care any longer about IRQs, thus the kernel will disable the IRQ if it's shared (unless we boot it with the 'irqpoll' option). So we must disable IRQs before changing the device status. Signed-off-by: Stefano Brivio <stefano.brivio@polimi.it> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* b43: Rewrite and fix rfkill initMichael Buesch2007-11-10
| | | | | | | | | | | | | | | | | | | The rfkill subsystem doesn't like code like that rfkill_allocate(); rfkill_register(); rfkill_unregister(); rfkill_register(); /* <- This will crash */ This sequence happens with modprobe b43 ifconfig wlanX up ifconfig wlanX down ifconfig wlanX up Fix this by always re-allocating the rfkill stuff before register.

* [PATCH] mac80211: revamp interface and filter configurationJohannes Berg2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drivers are currently supposed to keep track of monitor interfaces if they allow so-called "hard" monitor, and they are also supposed to keep track of multicast etc. This patch changes that, replaces the set_multicast_list() callback with a new configure_filter() callback that takes filter flags (FIF_*) instead of interface flags (IFF_*). For a driver, this means it should open the filter as much as necessary to get all frames requested by the filter flags. Accordingly, the filter flags are named "positively", e.g. FIF_ALLMULTI. Multicast filtering is a bit special in that drivers that have no multicast address filters need to allow multicast frames through when either the FIF_ALLMULTI flag is set or when the mc_count value is positive. At the same time, drivers are no longer notified about monitor interfaces at all, this means they now need to implement the start() and stop() callbacks and the new change_filter_flags() callback. Also, the start()/stop() ordering changed, start() is now called *before* any add_interface() as it really should be, and stop() after any remove_interface(). The patch also changes the behaviour of setting the bssid to multicast for scanning when IEEE80211_HW_NO_PROBE_FILTERING is set; the IEEE80211_HW_NO_PROBE_FILTERING flag is removed and the filter flag FIF_BCN_PRBRESP_PROMISC introduced. This is a lot more efficient for hardware like b43 that supports it and other hardware can still set the BSSID to all-ones.

| | | | | | | | | | | This adds support for turning the radio off in software.
