2010-01-05mwl8k: handle station database update for AP's sta entry via ->sta_notify()Lennert Buytenhek
Inserting and removing a hardware station database entry for the AP when we are in managed mode is currently done in ->bss_info_changed(). To prepare for adding AP mode support, implement the ->sta_notify() driver method, and let that handle inserting and removing the hardware station database entry for our AP instead.

2010-01-05mac80211: fix ieee80211_change_mac() to use struct sockaddrKalle Valo
Setting the mac address from user space was buggy. For example, when executing this command: ip link set wlan0 address 00:1f:df:88:cd:55 mac80211 used the address 01:00:00:1f:df:88 instead. It was shifted two bytes. The reason was that the addr (type of void *) provided to ieee80211_change_mac() is actually of type struct sockaddr, not just the mac address array. Also the call to eth_mac_addr() expects the address to be struct sockaddr. Signed-off-by: Kalle Valo <kalle.valo@nokia.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

Commit 250cce26d5d03337aec4ff8405121f026adb4a89 uses UTS_RELEASE as the the in-tree iwlwifi driver version. However the inclusion of generated/utsrelease.h makes it a unpleasant behaviour to recompile the driver everytime when utsrelease.h is updated. In fact, the driver module is already built with the UTS_RELEASE information via vermagic of modinfo.

2009-12-28cfg80211: add remain-on-channel commandJouni Malinen
Add new commands for requesting the driver to remain awake on a specified channel for the specified amount of time (and another command to cancel such an operation). This can be used to implement userspace-controlled off-channel operations, like Public Action frame exchange on another channel than the operation channel. The off-channel operation should behave similarly to scan, i.e. the local station (if associated) moves into power save mode to request the AP to buffer frames for it and then moves to the other channel to allow the off-channel operation to be completed. The duration parameter can be used to request enough time to receive a response from the target station.

2009-12-28mac80211: split up and insert custom IEs correctlyJohannes Berg
Currently, we insert all user-specified IEs before the HT IE for association, and after the HT IE for probe requests. For association, that's correct only if the user-specified IEs are RSN only, incorrect in all other cases including WPA. Change this to split apart the user-specified IEs in two places for association: before the HT IE (e.g. RSN), after the HT IE (generally empty right now I think?) and after WMM (all other vendor-specific IEs). For probes, split the IEs in different places to be correct according to the spec. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-12-28mac80211: refactor associationJohannes Berg
Refactor the code to reserve an skb of the right size (instead of hoping 200 bytes are enough forever), and also put HT IE generation into an own function. Additionally, put the HT IE before the vendor-specific WMM IE. This still leaves things not quite ordered correctly, due to user-specified IEs, add a note about that for now.

2009-12-28mac80211: rewrite a few work messagesJohannes Berg

2009-12-28mac80211: generalise work handlingJohannes Berg
In order to use auth/assoc for different purposes other than MLME, it needs to be split up. For other purposes, a generic work handling (potentially on another channel) will be useful. To achieve that, this patch moves much of the MLME work handling out of mlme into a new work API. The API can currently handle probing a specific AP, authentication and association. The MLME previously handled probe/authentication as one step and will continue to do so, but they are separate in the new work handling. Work items are RCU-managed to be able to check for existence of an item for a specific frame in the RX path, but they can be re-used which the MLME right now will do for its combined probe/auth step.

2009-12-28mac80211: generalise management work a bitJohannes Berg
As a first step of generalising management work, this renames a few things and puts more information directly into the struct so that auth/assoc need not access the BSS pointer as often -- in fact it can be removed from auth completely. Also since the previous patch made sure a new work item is used for association, we can make the different data a union.

2009-12-28mac80211: let cfg80211 manage auth stateJohannes Berg
mac80211 currently hangs on to the auth state by keeping it on the work list. That can lead to confusing behaviour like rejecting scans while authenticated to any AP (but not yet associated.) It also means that it needs to keep track of the work struct while associated for when it gets disassociated (or disassociates.) Change this to free the work struct after the authentication completed successfully and allocate a new one for associating, thereby letting cfg80211 manage the auth state. Another change necessary for this is to tell cfg80211 about all unicast deauth frames sent to mac80211 since now it can no longer check the auth state, but that check was racy anyway.

2009-12-28mac80211: introduce flush operationJohannes Berg
We've long lacked a good confirmation that frames have really gone out, e.g. before going off-channel for a scan.

It is checked in add_interface, but there it is easily replaced with a check of priv->vif. If that information should become necessary, it is available in vif->type anyway. It is also checked in led_turn_on and led_turn_off, where I made the substitutions as described above. Of course, these checks seem to have been incorrect since the driver was using NL80211_IFTYPE_MONITOR to indicate no interface rather than NL80211_IFTYPE_UNSPECIFIED. Anyway, I think these checks may be extraneous...? Signed-off-by: John W. Linville <linville@tuxdriver.com>
