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:

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. Patch fix not cancel scanning when restarting firmware, what is one of the causes of wdev_cleanup_work warning (together with permanent network connection lost) reported at https://bugzilla.redhat.com/show_bug.cgi?id=593566Signed-off-by:

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:

The iwl_adjust_beacon_interval function is a bit of black magic, so add comments to it describing what it does. Also, in the case when there's no beacon interval set, program the default into the device (instead of adjusting, which results in the max) since using the max in that case interacts badly with dual-mode/PAN parameters. Also update the PAN parameters accordingly and use the same constant as here. Signed-off-by:

In dual-mode, a number of scenarios need to be considered, and the firmware can be very picky about them. Adjust the timing (most importantly the beacon interval) according to the different modes. Signed-off-by:

The default LQ is filled decreasingly using iwl_get_prev_ieee_rate from a starting rate. Since the starting rate is already the lowest one for a specific band it should be actually filled evenly with the starting rate: 1M and 6M for 5.2GHZ and 2.4GH respectively. The bug is that for for A or G-only it decreases to CCK rates which are not supported. iwl_get_prev_ieee_rate function is just not band aware. This affects broadcast station which lq table is not updated by rs algorithm G-only scenario is not treated by this patch iwl_get_prev_ieee_rate is removed completely as it is not used in other contexts Signed-off-by:

The function has an unsigned return type, but returns a negative constant to indicate an error condition. Another error condition in the same function is indicated by returning 0, and indeed the only call to the function checks for 0 to detect errors, so the return of a negative value it converted to a return of 0. A sematic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @exists@ identifier f; constant C; @@ unsigned f(...) { <+... * return -C; ...+> } // </smpl> Signed-off-by:
