Since AR9003 uses a global tx status queue, processing tx status outside of the regular tx tasklet is dangerous and messes up hardware/software synchronization of tx status events. Signed-off-by:

The approach of this change is flawed, as it triggers tx status processing from more callsites, yet the chips only have one global tx status queue. Subsequent patches will properly fix the issue that this one tried to address. Signed-off-by:

When authentication type is configured to NL80211_AUTHTYPE_AUTOMATIC, driver tries to connect using open mode. The association is failed if AP is configured in shared mode. This patch adds code to try association using shared mode as well if open mode association fails. Now since we returned exact error code in association response handler (instead of -1), corresponding changes are done in mwifiex_process_cmdresp(). Signed-off-by:

That commit intended for 3.4 renamed IEEE80211_TX_CTL_POLL_RESPONSE as IEEE80211_TX_CTL_NO_PS_BUFFER. Meanwhile, "carl9170: fix frame delivery if sta is in powersave mode" added a reference to IEEE80211_TX_CTL_POLL_RESPONSE in the fixes stream for 3.3. This simple patch fixes that merge boo-boo.

Previous RX error checking was done exclusive-or for different error types and caused DFS pulse events to be dropped when other error flags (e.g. CRC) were set simultaneously. This patch decouples PHY error processing from other types and ensures that all pulses detected by HW are accounted by the pattern detector. Signed-off-by:

Remove the enum il_calib. It defined one identifier: IL_CALIB_MAX. Remove the function il4965_calib_free_results. It was doing nothing because IL_CALIB_MAX is zero. Next, remove calib_results from the il_priv structure and also remove the associated return type/struct il_calib_result. Signed-off-by:

This renames the IEEE80211_TX_CTL_POLL_RESPONSE TX flag to IEEE80211_TX_CTL_NO_PS_BUFFER and also uses it for non-bufferable MMPDUs (all MMPDUs but deauth, disassoc and action frames.) Previously, mac80211 would let the MMPDU through but not set the flag so drivers supporting some hardware aids for avoiding the PS races would then reject the frame. Signed-off-by:

It should have been removed by commit "mwifiex: use cfg80211 dynamic scan..." (7c6fa2a8 ..) after adding code to avoid an extra scan during association because scan entries are valid for 15 seconds in cfg80211 stack. Signed-off-by:

The association sequence looks (roughly) like this now: * set BSSID * set station to EXIST state * send auth * set station to AUTH state * send assoc * set station to ASSOC state * set BSS info to associated In contrast, the deauth/disassoc sequence is the other way around: * clear BSSID/BSS info state * remove station * send deauth/disassoc (in some cases the last two steps are reversed.) This patch encodes the entire sequence in the ieee80211_set_disassoc() function and changes it to be like this, for good measure with an explicit flush: * send deauth/disassoc * flush * remove station * clear BSSID/BSS info state At least iwlwifi gets confused with the other sequence in P2P mode and complains that it wasn't able to flush the queues.

When ieee80211_set_disassoc() is called with the tx argument set to true, it will send DelBA out to the peer. This isn't useful or necessary in a few cases where we do it today, those being when we lost the connection or when the supplicant explicitly asked us to not tell the AP. Signed-off-by:

Instead of calling cfg80211 in ieee80211_send_deauth_disassoc() pass out the frame and call it from the caller. That saves the SKB allocation if we don't actually want to send the frame and enables us to make the ordering smarter in the future. Signed-off-by:

I am running Debian testing kernel 3.1.0-1-amd64, using a 079b:0062 Sagem XG-76NA 802.11bg stick. Upon zd1211rw interface bringup (ifconfig wlan0 up) I get the following timeout: [ 950.330573] zd1211rw 1-3:1.0: phy2 [ 955.108510] zd1211rw 1-3:1.0: firmware version 4725 [ 955.148532] zd1211rw 1-3:1.0: zd1211b chip 079b:0062 v4810 high 00-19-70 AL2230_RF pa0 g--NS [snip] [ 955.204072] zd1211rw 1-3:1.0: error ioread32(CR_REG1): -110 A second ifconfig wlan0 up brings the interface up without problems. After a bit more debugging, the call trace is the following: [10241.028130] zd1211rw 1-3:1.0: zd_chip_lock_phy_regs: error ioread32(CR_REG1): -110 [10241.028140] zd1211rw 1-3:1.0: zd_switch_radio_on: failed to lock PHY regs [10241.028148] zd1211rw 1-3:1.0: zd_op_start: failed to set radio on Adding a 10 milliseconds delay between the call to set_mc_hash() and zd_chip_switch_radio_on() allows successful interface bringups in all cases and matches what the vendor driver did.

Nicolas Cavallari discovered that carl9170 has some serious problems delivering data to sleeping stations. It turns out that the driver was not honoring two important flags (IEEE80211_TX_CTL_POLL_RESPONSE and IEEE80211_TX_CTL_CLEAR_PS_FILT) which are set on frames that should be sent although the receiving station is still in powersave mode.

On Access Point mode, when transmitting a packet, if the destination station is in powersave mode, we abort transmitting the packet to the device queue, but we do not reclaim the allocated memory. Given enough packets, we can go in a state where there is no packet on the device queue, but we think the device has no memory left, so no packet gets transmitted, connections breaks and the AP stops working. This undo the allocation done in the TX path when the station is in power-save mode. Signed-off-by:
