* net: use symbolic values for ndo_start_xmit() return codesPatrick McHardy2009-06-131-1/+1
| | | | | | | | | | Convert magic values 1 and -1 to NETDEV_TX_BUSY and NETDEV_TX_LOCKED respectively. 0 (NETDEV_TX_OK) is not changed to keep the noise down, except in very few cases where its in direct proximity to one of the other values.

* mac80211: disable PS while probing APJohannes Berg2009-06-101-12/+33
| | | | | | | | | | | | When associated, but probing the AP because we detected beacon loss, we need to disable powersave to be able to receive the probe response. Change the code to do that by checking whether we're trying to probe when determining the possibility of going into PS, and recalculate the PS ability at the necessary spots.

* mac80211: disable moving between PS modes during scanLuis R. Rodriguez2009-06-102-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We don't want to trigger moving between PS mode during scan, because then we will sometimes end up sending nullfunc frames during scan. We're supposed to only send one prior to scan and after scan. This fixes an oops which occured due to an assert in ath9k: http://marc.info/?l=linux-wireless&m=124277331319024 The assert was happening because the rate control algorithm figures it should find at least one valid dual stream or single stream rate. Since we allow mac80211 to send nullfunc frames during scan and dynamic PS was enabled at times we ended up trying to send nullfunc frames for the target sta on the wrong band for which we have no valid rate to communicate with it. This breaks the assumptions in rate control. We determine we also need to disable moving between PS modes when not associated so lets just add that now as well, and we should not have a ps_sdata when that interface cannot actually go into PS because it's not associated.

* mac80211: do not pass PS frames out of mac80211 againJohannes Berg2009-06-106-73/+69
| | | | | | | | | | | | | | | | | | | In order to handle powersave frames properly we had needed to pass these out to the device queues again, and introduce the skb->requeue bit. This, however, also has unnecessary overhead by needing to 'clean up' already tried frames, and this clean-up code is also buggy when software encryption is used. Instead of sending the frames via the master netdev queue again, simply put them into the pending queue. This also fixes a problem where frames for that particular station could be reordered when some were still on the software queues and older ones are re-injected into the software queue after them.

* mac80211: fix minstrel single-rate memory corruptionBob Copeland2009-06-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The minstrel rate controller periodically looks up rate indexes in a sampling table. When accessing a specific row and column, minstrel correctly does a bounds check which, on the surface, appears to handle the case where mi->n_rates < 2. However, mi->sample_idx is actually defined as an unsigned, so the right hand side is taken to be a huge positive number when negative, and the check will always fail. Consequently, the RC will overrun the array and cause random memory corruption when communicating with a peer that has only a single rate. The max value of mi->sample_idx is around 25 so casting to int should have no ill effects. Without the change, uptime is a few minutes under load with an AP that has a single hard-coded rate, and both the AP and STA could potentially crash. With the change, both lasted 12 hours with a steady load. Thanks to Ognjen Maric for providing the single-rate clue so I could reproduce this. This fixes http://bugzilla.kernel.org/show_bug.cgi?id=12490 on the regression list (also http://bugzilla.kernel.org/show_bug.cgi?id=13000). Cc: stable@kernel.org Reported-by: Sergey S.

* mac80211: fix managed mode BSSID handlingJohannes Berg2009-05-202-7/+19
| | | | | | | | | | | | | | | | | | | | | | Currently, we will ask the driver to configure right away when somebody changes the desired BSSID. That's totally strange because then we will configure the driver without even knowing whether the BSS exists. Change this to only configure the BSSID when associated, and configure a zero BSSID when not associated. As a side effect, this fixes an issue with the iwlwifi driver which doesn't implement sta_notify properly and uses the BSSID instead and gets very confused if the BSSID is cleared before we disassociate, which results in the warning Marcel posted [1] and iwlwifi bug 1995 [2].

| | | | | | | | | | | | | | | | | | | When the genIE hasn't changed there's no reason to kick the state machine since it won't be able to do anything new -- doing this decreases the useless work we do for reassociating because if we do kick the state machine it will try to find a usable BSS but there might not be one because wpa_supplicant will only change the BSSID a little later. In a sense this is a workaround for userspace behaviour, but on the other hand userspace cannot really keep track of what the kernel currently has for genIE since any process could have changed that while wpa_supplicant wasn't looking.

| | | | | | | | | | | | | | | | | If the AP includes our AID in the TIM IE, we need to process the Beacon frame as far as PS is concerned (send PS-Poll or nullfunc data with PM=0). The previous code skipped this in cases where the CRC value did not change and it would not change if the AP continues including our AID in the TIM.. There is no need to count the crc32 value for directed_tim with this change, so we can remove that part. In order not to change the order of operations (i.e., update WMM parameters prior to sending PS-Poll), the CRC match is checked twice as only after the PS processing step, the rest of the function is skipped if nothing changed in the Beacon.

| | | | | | | | | | | | | | | | | | | | | We forgot to cancel all timers in mac80211 when suspending. In particular we forgot to deal with some things that can cause hardware reconfiguration -- while it is down. While at it we go ahead and add a warning in ieee80211_sta_work() if its run while the suspend->resume cycle is in effect. This should not happen and if it does it would indicate there is a bug lurking in either mac80211 or mac80211 drivers. With this now wpa_supplicant doesn't blink when I go to suspend and resume where as before there where issues with some timers running during the suspend->resume cycle.

However, it is for managed mode only and uses the structures for that mode only so having it in a more generic file can be confusing. Additionally, my next patch gets simpler with the code here.

This patch introduces a new nl80211 attribute that contains a set/mask for station flags, and updates the internal API (and mac80211) to mirror that. The new attribute is parsed before falling back to the old so that userspace can specify both (if it can) to work on all kernels.

* | cfg80211: implement wext key handlingJohannes Berg2009-05-131-276/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move key handling wireless extension ioctls from mac80211 to cfg80211 so that all drivers that implement the cfg80211 operations get wext compatibility. Note that this drops the SIOCGIWENCODE ioctl support for getting IW_ENCODE_RESTRICTED/IW_ENCODE_OPEN. This means that iwconfig will no longer report "Security mode:open" or "Security mode:restricted" for mac80211. However, what we displayed there (the authentication algo used) was actually wrong -- linux/wireless.h states that this setting is meant to differentiate between "Refuse non-encoded packets" and "Accept non-encoded packets". (Combined with "cfg80211: fix a couple of bugs with key ioctls". -- JWL) Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* | mac80211: properly track HT operation_modeJohannes Berg2009-05-112-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | When we disassociate, we set the channel to non-HT which obviously invalidates any ht_operation_mode setting. But when we then associate with the next AP again, we might still have the ht_operation_mode from the previous AP cached and fail to configure the hardware with the new (but unchanged) operation mode. This patch fixes it by separately tracking whether our cache is valid. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* | mac80211: move HT operation mode BSS infoJohannes Berg2009-05-111-7/+4
| | | | | | | | | | | | | | | | | | There really is no need to have a separate struct for a single variable. The fact that it exists is due to the code legacy, but we can remove that now. Very simple. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
