2012-02-29mac80211: handle non-bufferable MMPDUs correctlyJohannes Berg6-18/+30
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.

2012-02-29mwifiex: remove unnecessary enum MWIFIEX_802_11_WEP_STATUSAmitkumar Karwar7-44/+29
Instead of defining an 'enum', we can simply use 'u8' flag for WEP status. Rename 'wep_status' to 'wep_enabled' to match with 'wpa_enabled' and 'wpa2_enabled'.

2012-02-29mwifiex: remove redundant scan operationAmitkumar Karwar1-6/+0
It should have been removed by commit "mwifiex: use cfg80211 dynamic scan..." (7c6fa2a843..) after adding code to avoid an extra scan during association because scan entries are valid for 15 seconds in cfg80211 stack.

2012-02-29mac80211: make deauth/disassoc sequence more naturalJohannes Berg1-37/+47
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.

2012-02-29mac80211: fix ieee80211_set_disassoc() sending DelBAJohannes Berg1-3/+3
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.

2012-02-29mac80211: dont call cfg80211 from ieee80211_send_deauth_disassocJohannes Berg1-33/+38
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.

2012-02-29zd1211rw: wait between setting hash table and powering radio onFlorian Fainelli1-1/+11
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.

The comment for sta_info_flush() states "Returns the number of removed STA entries" but that isn't actually true.

2012-02-27mac80211: fix auth/assoc data & timer leakJohannes Berg3-0/+16
When removing an interface while it is in the process of authenticating or associating, we leak the auth_data or assoc_data, and leave the timer pending. The timer then crashes the system when it fires as its data is gone. Fix this by explicitly deleting all the data when the interface is removed. This uncovered another bug -- this problem should have been detected by the sta_info_flush() warning but that function doesn't ever return non-zero, I'll fix that in a separate patch.
