* mac80211: simplify scan startJohannes Berg2008-09-11
| | | | | | | | ieee80211_sta_start_scan() can very well take a non-NULL ssid pointer with a zero ssid_len. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* mac80211: refactor and move scan RX codeJohannes Berg2008-09-11
| | | | | | | | | | | | | | | This patch refactors some code and moves the scan RX function to scan.c. More importantly, however, it changes it so that the MLME's beacon/probe_resp functions aren't invoked when scanning so that we can remove a "if (scanning)" conditions from two places. There's a very slight behavioural change in this patch: now, when scanning, IBSS and mesh aren't updated even on the same channel.

* mac80211: start moving scan code from mlmeJohannes Berg2008-09-11

* mac80211: use sdata pointer for scan interfaceJohannes Berg2008-09-11
| | | | | | | | | Since we now use sdata pointers most of the time, using a netdev pointer here is somewhat artificial, use an sdata pointer instead.

* mac80211: stop queues before carrier offTomas Winkler2008-09-11
| | | | | | | | | | | | | During testing of the disassociation fixes, Tomas noticed that it was possible to run into a situation where you'd suddenly get a few "wlan0: dropped frame to <AP> (unauthorized port)" messages and I found this to be due to the AP's sta_info having been removed but netif_carrier_off not having removed/stopped traffic yet. To avoid that, stop the queue for the interface (and avoid bringing them up when another vif scans when they weren't up.)

* mac80211: remove disassociation code from ieee80211_set_associatedTomas Winkler2008-09-11
| | | | | | | | | | | | This patch moves disassociation code from ieee80211_set_associated to ieee80211_set_disassoc. To reduce code duplication, it introduces the ieee80211_sta_send_apinfo function.

* mac80211: disassociate when moving to new BSSTomas Winkler2008-09-11
| | | | | | | | | | | | | This patch makes the MLME cleanly disassociate from the current BSS when leaving it for a new one. This is not just nicer to the old AP (we're leaving it, might as well tell it!) but also required for some drivers that keep track of the station we're associated with, they'd get confused because they'd think we are associated with two APs.

| | | | | | | | | | The action frame length checks are one too small, there's not just an action code as the comment makes you believe, there's a category code too, and the category code is required in each action frame (hence part of IEEE80211_MIN_ACTION_SIZE).

* mac80211: BSS info: check channel firstJohannes Berg2008-09-11
| | | | | | | | | | | When we receive information about a BSS we check at some point whether or not we think we're allowed to use the channel it is on, but we do that fairly late. I don't think we should do it that late, so do it earlier to avoid doing IBSS/mesh stuff on that channel and then getting confused because it's disabled.

* mac80211: make conf_tx non-atomicJohannes Berg2008-09-11
| | | | | | | | | | | The conf_tx callback currently needs to be atomic, this requirement is just because it can be called from scanning. This rearranges it slightly to only update while not scanning (which is fine, we'll be getting beacons when associated) and thus removes the atomic requirement.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch address some IBSS rate issues introduced or not covered by "mac80211: eliminate IBSS warning in rate_lowest_index()" and "cfg80211 API for channels/bitrates, mac80211 and driver conversion". This patch: 1. Moves addition of IBSS station from prepare_for_handlers to ieee80211_rx_bss_info when triggered from beacon eliminating bogus supported rates. 2. Initialize properly supported rates also in IBSS merging 3. Ensure that mandatory rates are always added into supported rates. This is needed in case when station addition is triggered from non beacon/probe packet. Some management frames need to be sent 4. Remove initialization of supported rates from self rates. This path was dead code after 6bc37c06bc4 and in general incorrect.

| * mac80211: don't send empty extended rates IEJan-Espen Pettersen2008-08-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The association request includes a list of supported data rates. 802.11b: 4 supported rates. 802.11g: 12 (8 + 4) supported rates. 802.11a: 8 supported rates. The rates tag of the assoc request has room for only 8 rates. In case of 802.11g an extended rate tag is appended. However in net/wireless/mlme.c an extended (empty) rate tag is also appended if the number of rates is exact 8. This empty (length=0) extended rates tag causes some APs to deny association with code 18 (unsupported rates). These APs include my ZyXEL G-570U, and according to Tomas Winkler som Cisco APs. 'If count == 8' has been used to check for the need for an extended rates tag. But count would also be equal to 8 if the for loop exited because of no more supported rates. Therefore a check for count being less than rates_len would seem more correct.

| * mac80211: Use IWEVASSOCREQIE instead of IWEVCUSTOMJouni Malinen2008-08-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous code was using IWEVCUSTOM to report IEs from AssocReq and AssocResp frames into user space. This can easily hit the 256 byte limit (IW_CUSTOM_MAX) with APs that include number of vendor IEs in AssocResp. This results in the event message not being sent and dmesg showing "wlan0 (WE) : Wireless Event too big (366)" type of errors. Convert mac80211 to use IWEVASSOCREQIE/IWEVASSOCRESPIE to avoid the issue of being unable to send association IEs as wireless events. These newer event types use binary encoding and larger maximum size (IW_GENERIC_IE_MAX = 1024), so the likelyhood of not being able to send the IEs is much smaller than with IWEVCUSTOM. As an extra benefit, the code is also quite a bit simpler since there is no need to allocate an extra buffer for hex encoding.

* | replace net_device arguments with ieee80211_{local,sub_if_data} as appropriateJasper Bryant-Greene2008-08-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch replaces net_device arguments to mac80211 internal functions with ieee80211_{local,sub_if_data} as appropriate. It also does the same for many 802.11s mesh functions, and changes the mesh path table to be indexed on sub_if_data rather than net_device. If the mesh part needs to be a separate patch let me know, but since mesh uses a lot of mac80211 functions which were being converted anyway, the changes go hand-in-hand somewhat. This patch probably does not convert all the functions which could be converted, but it is a large chunk and followup patches will be provided.

* mac80211: make master netdev handling saneJohannes Berg2008-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, almost every interface type has a 'bss' pointer pointing to BSS information. This BSS information, however, is for a _local_ BSS, not for the BSS we joined, so having it on a STA mode interface makes little sense, but now they have it pointing to the master device, which is an AP mode virtual interface. However, except for some bitrate control data, this pointer is only used in AP/VLAN modes (for power saving stations.) Overall, it is not necessary to even have the master netdev be a valid virtual interface, and it doesn't have to be on the list of interfaces either. This patch changes the master netdev to be special, it now - no longer is on the list of virtual interfaces, which lets me remove a lot of tests for that - no longer has sub_if_data attached, since that isn't used Additionally, this patch changes some vlan/ap mode handling that is related to these 'bss' pointers described above (but in the VLAN case they actually make sense because there they point to the AP they belong to); it also adds some debugging code to IEEE80211_DEV_TO_SUB_IF to validate it is not called on the master netdev any more.

* | mac80211: call bss_info_change only once upon disassociationTomas Winkler2008-07-08
| | | | | | | | | | | | | | | | | | | | This patch removes call of ieee80211_bss_info_change_notify from within ieee80211_reset_erp_info. This allows gathering all bss info changes into one call to the driver in the disassociation flow.
