2009-02-14net: replace __constant_{endian} uses in net headersHarvey Harrison14-101/+101
Base versions handle constant folding now. For headers exposed to userspace, we must only expose the __ prefixed versions. Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-02-13iwlwifi: fix FAT channel config for 5000 seriesReinette Chatre3-6/+8
The test to find out if we have FAT channels do not consider that the value of regulatory_bands for the 5000 series is larger than its eeprom size. Using the eeprom size is strange in itself. Use a new EEPROM_REGULATORY_BAND_NO_FAT to indicate no FAT support and test for that explicitly.

2009-02-13mac80211: split managed/ibss code a little moreJohannes Berg1-108/+146
It appears that you can completely mess up mac80211 in IBSS mode by sending it a disassoc or deauth: it'll stop queues and do a lot more but not ever do anything again. Fix this by not handling all those frames in IBSS mode, Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2009-02-13cfg80211: add more flexible BSS lookupJohannes Berg2-3/+19

2009-02-13cfg80211: allow users to request removing a BSSJohannes Berg2-0/+32
This patch introduces cfg80211_unlink_bss, a function to allow a driver to remove a BSS from the internal list and make it not show up in scan results any more -- this is to be used when the driver detects that the BSS is no longer available.

2009-02-13cfg80211: free_priv for BSS infoJohannes Berg3-1/+5
When cfg80211 users have their own allocated data in the per-BSS private data, they will need to free this when the BSS struct is destroyed. Add a free_priv method and fix one place where the BSS was kfree'd rather than released properly. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-02-13mac80211: dont add BSS when creating IBSSJohannes Berg3-58/+60
There's no need to create a BSS struct only to pass it to ieee80211_sta_join_ibss, so refactor this function into __ieee80211_sta_join_ibss which takes all the relevant paramters, and ieee80211_sta_join_ibss which takes a BSS struct (used when joining an IBSS that already has other members).

2009-02-13cfg80211/nl80211: scanning (and mac80211 update to use it)Johannes Berg21-383/+1546
This patch adds basic scan capability to cfg80211/nl80211 and changes mac80211 to use it. The BSS list that cfg80211 maintains is made driver-accessible with a private area in each BSS struct, but mac80211 doesn't yet use it. That's another large project.

2009-02-13mac80211: further cleanups to stopping BA sessionsJohannes Berg4-39/+44

2009-02-13mac80211: clean up BA session teardownJohannes Berg4-8/+7
The sta_info pointer can very well be passed to ieee80211_sta_tear_down_BA_sessions, this will later allow us to pass it through even further. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-02-13mac80211: fix aggregation timer lockupsJohannes Berg3-6/+43
As far as I can tell, there are possible lockups because both the RX session_timer and TX addba_resp_timer are del_timer_sync'ed under the sta spinlock which both timer functions take. Additionally, the TX agg code seems to leak memory when TX aggregation is not disabled before the sta_info is freed. Fix this by making the free code a little smarter in the RX agg case, and actually make the sta_info_destroy code free the TX agg info in the TX agg case. We won't notify the peer, but it'll notice something is wrong anyway, and normally this only happens after we've told it in some other way we will no longer talk to it.

2009-02-13mac80211: fix race in TX aggregationJohannes Berg1-47/+48
When disabling TX aggregation because it was rejected or from the timer (it was not accepted), there is a window where we first set the state to operation, unlock, and then undo the whole thing. Avoid that by splitting up the stop function. Also get rid of the pointless sta_info indirection in the timer. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-02-13mac80211: document TX aggregation (and small cleanup)Johannes Berg1-25/+51

2009-02-13mac80211: hardware should not deny going back to legacyJohannes Berg1-3/+2
Doing so would be an MLME protocol violation when the peer disabled the aggregation session. Quick driver review indicates that there are error codes passed all over the drivers but cannot ever be nonzero except in error conditions that would indicate mac80211 bugs. No real changes here, since no drivers currently can return -EBUSY. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-02-13mac80211: restrict aggregation to supported interface modesJohannes Berg4-3/+30
We can only support aggregation on AP/STA right now. HT isn't defined for IBSS, WDS or MESH. In the WDS/MESH cases it's not clear what to put into the IBSS field, and we don't handle that in the code at all. Also fix the code to handle VLAN correctly.

2009-02-13mac80211: restructure HT codeJohannes Berg5-857/+895

2009-02-13mac80211: remove bssid argument from prepare_for_handlersJohannes Berg1-4/+3

2009-02-13mac80211: fix beacon enable moreJohannes Berg1-2/+12
Hopefully the last required fix ... disable beaconing only on beaconing interfaces, and thus avoid calling ieee80211_if_config for purely virtual interfaces (those driver doesn't know about).

2009-02-13mac80211: disable IBSS beacon before joinJohannes Berg1-0/+2

2009-02-13zd1211rw: do not ratelimit no-opsJohannes Berg2-4/+8
It is rather confusing to see this in the log: [ 695.606877] __ratelimit: 40 callbacks suppressed [ 700.726878] __ratelimit: 40 callbacks suppressed without ever seeing any actual message. This is because zd1211rw doesn't compile out the net_ratelimit() call properly if debugging is not enabled. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2009-02-13mac80211: use ps-poll when dynamic power save mode is disabledKalle Valo3-3/+88
When a directed tim bit is set, mac80211 currently disables power save ands sends a null frame to the AP. But if dynamic power save is disabled, mac80211 will not enable power save ever gain. Fix this by adding ps-poll functionality to mac80211. When a directed tim bit is set, mac80211 sends a ps-poll frame to the AP and checks for the more data bit in the returned data frames. Using ps-poll is slower than waking up with null frame, but it's saves more power in cases where the traffic is low. Userspace can control if either ps-poll or null wakeup method is used by enabling and disabling dynamic power save. Signed-off-by: Kalle Valo <kalle.valo@nokia.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-02-13mac80211: remove multicast check from check_tim()Kalle Valo1-7/+4
Currently mac80211 checks for the multicast tim bit from beacons, disables power save and sends a null frame if the bit is set. This was added to support ath9k. But this is a bit controversial because the AP will send multicast frames immediately after the beacon and the time constraints are really high. Relying mac80211 to be fast enough here might not be reliable in all situations. And there's no need to send a null frame, AP will send the frames immediately after the dtim beacon no matter what. Also if dynamic power save is disabled (iwconfig wlan0 power timeout 0) currently mac80211 disables power save whenever the multicast bit is set but it's never enabled again after receiving the first multicast/broadcast frame. The current implementation is not usable on p54/stlc45xx and the easiest way to fix this is to remove the multicast tim bit check altogether. Handling multicast tim bit in host is rare, most of the designs do this in firmware/hardware, so it's better not to have it in mac80211. It's a lot better to do this in firmware/hardware, or if that's not possible it could be done in the driver. Also renamed the function to ieee80211_check_tim() to follow the style of the file.
