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:

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:

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:

Replace IWL_DEBUG_{INFO,HC,RC} to IWL_DEBUG_SCAN in iwl-scan.c file. Add some more IWL_DEBUG_SCAN messages. This will allow to fully debug scanning using only IWL_DL_SCAN flag. Also start one message sentence with capital letter, since that convention in iwl-scan.c file. Signed-off-by: -

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. Change code to force scan complete only when really needed: device goes down, interface is removed or scan timeout occurs. Signed-off-by:

Assure we complete scan in mac80211 when we abort scanning (scan_abort work) or scan timeout occurs (scan_check work). Currently iwl_scan_cancel_timeout() procedure force scan finish in mac80211 at the end of timeout loop, so we can use it in proper work functions. Signed-off-by:

If we do not get notification from hardware about scan complete, after timeout do mac80211 scan completion anyway. This assure we end scan in case of firmware hung. Patch fix one of the causes of wdev_cleanup_work warning reported at https://bugzilla.redhat.com/show_bug.cgi?id=593566Signed-off-by:

Assure (partially) we call ieee80211_scan_completed() only once when scan was requested from mac80211. 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. Still persist some cases when we behave wrong, that will be addressed in the next patches. Signed-off-by:

Stanislaw Gruszka authored
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. Signed-off-by:

When we are not able to send abort command to firmware, notify mac80211 that we complete scan, as we will newer do it lately. Check for all possible errors that low level sending command procedure does not check, to assure we catch all failures cases.

Always cancel scan when stooping device and scan is currently pending, we should newer have scan running after down device. To assure we start scan cancel from restart work we have to schedule abort_scan to different workqueue than priv->workqueue.

Move the scan completed flags handling so that we can notify mac80211 about aborted scans with the correct status. Also queue the scan_completed work before the BT status update so that it won't see the bits still set (unless a new scan was started in which case that's fine.) Signed-off-by:

Rather than duplicating all the checks and even in case of errors accepting the scan request from mac80211, we can push the checks to the caller and in all error cases reject the scan request right away (rather than accepting and then saying it was aborted). Signed-off-by:

Previously rt2x00 was always updating all erp related config variables even though mac80211 might only have changed one. Hence, pass the changed flags to the config_erp driver callback so that the driver can limit the changes to the correct values. This fixes an issue in AP mode where the beacon interval is not initialized (and thus zero) but still sent to the hardware causing an interrupt storm on rt2800pci hanging the system. Signed-off-by:

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:
