2011-05-10mac80211: don't start the dynamic ps timer if not associatedLuciano Coelho
When we are disconnecting, we set PS off, but this happens before we send the deauth/disassoc request. When the deauth/disassoc frames are sent, we trigger the dynamic ps timer, which then times out and turns PS back on. Thus, PS remains on after disconnecting, causing problems when associating again. This can be fixed by preventing the timer to start when we're not associated anymore. Signed-off-by: Luciano Coelho <coelho@ti.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2011-05-05mac80211: add basic support for WoWLANJohannes Berg
This adds basic support for the new WoWLAN configuration in mac80211. The behaviour is completely offloaded to the driver though, with two new callbacks (suspend/resume). Options for the driver include a complete reconfiguration after wakeup, and exposing all the triggers it wants to support.

This is based on (but now quite far from) the original work from Luis and Eliad. Add support for configuring WoWLAN triggers, and getting the configuration out again. Changes from the original patchset are too numerous to list, but one important change needs highlighting: the suspend() callback is passed NULL for the trigger configuration if userspace has not configured WoWLAN at all.

2011-05-05mac80211: Postpond ps timer if tx is stopped by othersRajkumar Manoharan
Whenever the driver's queue depth reaches the max, the queues are stopped by the driver till the driver can accept the frames. At the mean time dynamic_ps_timer can be expired due to not receiving packet from upper layer which could restart the transmission at the end of ps work. Due to the mismatch with driver state, mac80211 is unneccesarity buffering all the frames till the driver wakes up the queue. Check whether there is no transmit or the tx queues were stopped by some reasons. If any of the queue was stopped, the postpond ps timer and do not restart netif_tx.

Not doing so, sometimes stalls the transmission and the application has to be restarted to proceed further.

2011-05-05mac80211: Fix a warning due to skipping tailroom reservation for IVMohammed Shafi Shajakhan
The devices that require IV generation in software need tailroom reservation for ICVs used in TKIP or WEP encryptions. Currently, decision to skip the tailroom reservation in the tx path was taken only on whether driver wants MMIC to be generated in software or not. Following patch appends IV generation check for such decisions and fixes the following warning.

2011-05-02mac80211: consolidate MIC failure report handlingChristian Lamparter
Currently, mac80211 handles MIC failures differently depending on whenever they are detected by the stack's own software crypto or when are handed down from the driver. This patch tries to unify both by moving the special branch out of mac80211 rx hotpath and into into the software crypto part. This has the advantage that we can run a few more sanity checks on the data and verify if the key type was TKIP. This is very handy because several devices generate false postive MIC failure reports.

2011-04-12mac80211: Check for queued frames before entering power save.Vivek Natarajan
In a highly noisy environment, the tx rate of the driver drops and the application slows down since it has not yet received ACKs for the frames already queued in the hardware. Since this ACK may take more than 100ms, stopping the dev queues for entering PS at this stage breaks applications, WMM test cases in my testing. If there are frames already pending in the tx queue, postponing the PS logic helps to avoid redundant queue stops. When power save is enabled by default and in a noisy environment, this API certainly helps in improving the average throughput.

2011-04-04mac80211: remove the dependency on crypto_blkcipherFelix Fietkau
The only thing that using crypto_blkcipher with ecb does over just using arc4 directly is wrapping the encrypt/decrypt function into a for loop, looping over each individual character. To be able to do this, it pulls in around 40 kb worth of unnecessary kernel modules (at least on a MIPS embedded device). Using arc4 directly not only eliminates those dependencies, it also makes the code smaller. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-04-04mac80211: fix suppressing probe responses in ad-hoc modeFelix Fietkau
The commit "mac80211: reply to directed probes in IBSS" changed ad-hoc specific code to respond to unicast probe requests, even if drv_tx_last_beacon returns false, however due to confusion over the meaning of the IEEE80211_RX_RA_MATCH flag, it also unconditionally enabled responding to multicast probe requests. Fix this by explicitly checking for a multicast destination address instead. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
