2010-09-14mac80211: match only assigned bss in sta_info_get_bssJohannes Berg
sta_info_get_bss() is used to match STA pointers for VLAN/AP interfaces, but if the same station is also added to multiple other interfaces it will erroneously match because both pointers are NULL, fix this by ignoring NULL pointers here.

2010-09-14ath9k_hw: handle rx key missFelix Fietkau
If AR_KeyMiss is set in the rx descriptor and AR_RxFrameOK is unset, the hardware could not locate a valid key during a decryption attempt. In this case, the frame must not be reported as decrypted, otherwise mac80211 sees only random garbage. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Cc: stable@kernel.org Signed-off-by: John W.

2010-09-14ath9k: fix BSSID mask calculationFelix Fietkau
At the time the .add_interface driver op is called, the interface has not been marked as running yet, so ieee80211_iterate_active_interfaces will not pass it to the iterator function. Because of this, the calculated BSSID mask is wrong, which breaks multi-BSS operation. Additionally, the current way of comparing all addresses against each other is pointless, as the hardware only uses the hardware MAC address and the BSSID mask for matching the destination address, so all the address array reallocation is completely unnecessary. This patch simplifies the logic by setting the initial mask bytes to 0xff and removing all bits in the iterator call that don't match the hardware MAC address. It also calls the iterator for the vif that was passed to add_interface() Signed-off-by: Felix Fietkau <nbd@openwrt.org> Tested-by: Ben Greear <greearb@candelatech.com> Signed-off-by: John W.

2010-09-14ath9k_htc: Fix CPU usage issue during scan periodRajkumar Manoharan
The CPU consumption during the scan period is high, since the register write go over Interrupt endpoint. On downloading the firmware to the target, the USB descriptors are 'patched' to change the type of the endpoints from Interrupt to Bulk. With this fix, the CPU usage during a scan run comes down to acceptable levels. Signed-off-by: Rajkumar Manoharan <rmanoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-09-14iwlwifi: do not force complete scan too earlyStanislaw Gruszka
Currently we force scan complete at the end of iwl_scan_cancel_timeout function. This cause race condition when we can get a new scan request from mac80211 and complete it by iwl_bg_complete from older scan.

Code path that first clear STATUS_SCANNING bit is responsible to call ieee80211_scan_completed(). Before the call, we check if mac80211 really request the scan.

2010-09-14iwlwifi: rework iwl_scan_cancel_timeoutStanislaw Gruszka
Since on timeout version of iwl_scan_cancel procedure we can sleep, do not have to schedule abort_scan work to begin and perform scanning, can do this directly. Also now, as we do not queue abort_scan from restart work anymore, we can queue abort_scan to priv->workqueue. Don't drop mutex when waiting for scan complete. Use STATUS_HW_SCAN bit to check if scanning is currently pending, because STATUS_SCANNING will be cleared only with priv->mutex taken.

Hence, pass the changed flags to the config_erp driver callback so that the driver can limit the changes to the correct values.

2010-09-14rt2x00: Antenna diversity does not work in 2.6.35Lars Ericsson
The test if antenna diversity is at all enabled uses a local variable 'flags' to prepare the test condition, but uses 'ant->flags' when the test is evaluated. The effect is that the diversity evaluation will never start. I can see two solutions, use the 'flag' in the test condition or revert the local flag change. My attached patch took alternative two. Then the evaluation start but it will still not switch antenna. The problem is a code section in rt2x00lib_config_antenna (). The effect of that code section is that any change the diversity function perform will be effectively shorten and no antenna selection command issued. The attached patch will filter out any ANTENNA_SW_DIVERSITY setting but forward all other Signed-off-by: Lars Ericsson <lars_ericsson@telia.com> Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.
