* | | | mac80211: Fix bug in computing crc over dynamic IEs in beaconVasanthakumar Thiagarajan2009-12-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On a 32-bit machine, BIT() macro does not give the required bit value if the bit is mroe than 31. In ieee802_11_parse_elems_crc(), BIT() is suppossed to get the bit value more than 31 (42 (id of ERP_INFO_IE), 37 (CHANNEL_SWITCH_IE), (42), 32 (POWER_CONSTRAINT_IE), 45 (HT_CAP_IE), 61 (HT_INFO_IE)). As we do not get the required bit value for the above IEs, crc over these IEs are never calculated, so any dynamic change in these IEs after the association is not really handled on 32-bit platforms. This patch fixes this issue. Cc: stable@kernel.org Signed-off-by: Vasanthakumar Thiagarajan <vasanth@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Not only ps_sdata but also IEEE80211_CONF_PS is to be considered before restoring PS in scan_ps_disable(). For instance, when ps_sdata is set but CONF_PS is not set just because the dynamic timer is still running, a sw scan leads to setting of CONF_PS in scan_ps_disable instead of restarting the dynamic PS timer. Also for the above case, a null data frame is to be sent after returning to operating channel which was not happening with the current implementation. This patch fixes this too.

* | | | mac80211: recalculate idle later in MLMEJohannes Berg2009-12-071-2/+8
|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | hwsim testing has revealed that when the MLME recalculates the idle state of the device, it sometimes does so before sending the final deauthentication or disassociation frame. This patch changes the place where the idle state is recalculated, but of course driver transmit is typically asynchronous while configuration is expected to be synchronous, so it doesn't fix all possible cases yet.

I intentially didn't initialise and use the skb queue's spinlock, but in this place forgot that the code variant that doesn't touch the spinlock is needed.

It was not supposed to remove TX status reporting for injected frames, but ended up doing it by checking the injected flag in skb->cb only after that field had been cleared with memset.. Fix this by taking a local copy of the injected flag before skb->cb is cleared. This broke user space applications that depend on getting TX status notifications for injected data frames. For example, STA inactivity poll from hostapd did not work and ended up kicking out stations even if they were still present. Signed-off-by: Jouni Malinen <j@w1.fi> Signed-off-by: John W.

The previous patch moved the code there, and this patch now hooks it up in that place by introducing a list of skbs that are then processed by the remaining handlers. The list may be empty if the function is buffering the skb to release it later. The only change needed to the RX data is that the crypto handler needs to clear the key that may be set from a previous loop iteration, and that not everything can be in the rx flags now.

As the comment indicates, the BUG_ON can be removed since the ampdu_action callback must already exist when the state is != IDLE. The second problem isn't easily exploitable but there's a race condition due to unconditionally setting the state to OPERATIONAL when a delBA frame is received, even when no aggregation session was ever initiated. All the drivers accept stopping the session even then, but that opens a race window where crashes could happen before the driver accepts it. Right now, a WARN_ON may happen with non-HT drivers, while the race opens only for HT drivers. For this case, there are two things necessary to fix it: 1) don't process spurious delBA frames, and be more careful about the session state; don't drop the lock 2) HT drivers need to be prepared to handle a session stop even before the session was really started -- this is true for all drivers (that support aggregation) but iwlwifi which can be fixed easily. The other HT drivers (ath9k and ar9170) are behaving properly already.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When mac80211 resumes, it currently first sets suspended to false so the driver can start doing things and we can receive frames. However, if we actually receive frames then it can end up starting some work which adds timers and then later runs into a BUG_ON in the timer code because it tries add_timer() on a pending timer. Fix this by keeping track of the resuming process by introducing a new variable 'resuming' which gets set to true early on instead of setting 'suspended' to false, and allow queueing work but not receiving frames while resuming.

Linus pointed out that del_timer_sync() isn't actually needed if we make the timer able to deal with no longer being needed when it gets queued _while_ we're in the locked section that also deletes it. For that the timer function only needs to check the HT_ADDBA_RECEIVED_MSK bit as well as the HT_ADDBA_REQUESTED_MSK bit, only if the former is clear should it do anything.

Every time this happens we print a deauth message and send a deauth frame, but both of that is rather confusing. Avoid it by aborting the authentication process silently, and telling cfg80211 about that. The patch looks larger than it really is: __cfg80211_auth_remove() is split out from cfg80211_send_auth_timeout(), there's no new code except __cfg80211_auth_canceled() (a one-liner) and the mac80211 bits (7 new lines of code).

Also, rt2x00 uses that bit for its own purposes and seems to require it being set for all frames, but that can be fixed in rt2x00. This doesn't really change anything for any drivers but in the future drivers using hw-rate control may opt to not report TX status for frames that don't have the IEEE80211_TX_CTL_REQ_TX_STATUS flag set.

| * | | cfg80211: introduce capability for 4addr modeJohannes Berg2009-11-196-29/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's very likely that not many devices will support four-address mode in station or AP mode so introduce capability bits for both modes, set them in mac80211 and check them when userspace tries to use the mode. Also, keep track of 4addr in cfg80211 (wireless_dev) and not in mac80211 any more. mac80211 can also be improved for the VLAN case by not looking at the 4addr flag but maintaining the station pointer for it correctly. However, keep track of use_4addr for station mode in mac80211 to avoid all the derefs. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

| * | | mac80211: make software rate control optionalJohannes Berg2009-11-185-13/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some devices implement the entire rate control in firmware in some way, like wl1271 or like iwlwifi which does some things in software but not a lot. Therefore generic software rate control is rather useless for them and just adds avoidable overhead to the transmit path. It's fairly simple to let drivers indicate that they do not need rate control, but they need to fulfil a number of conditions that we encode in WARN_ONs.

| * | | mac80211: use fixed broadcast addressJohannes Berg2009-11-186-19/+27

Since we already have an instance in tkip.c, which will be shared if it is marked static const, doing this reduces text size at no data/bss cost. The real motivation for this is, of course, the desire to get rid of almost all uses of netdevs in mac80211 so that auditing their use becomes easier.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some code currently assumes that there's a valid rate pointer even in the HT case, but there can't be. To reduce reliance on that, remove the rate pointer from the RX data struct and pass it where it's needed. Also, for now, in radiotap announce HT frames as having a DYN channel type, and remove their rate from cooked monitor radiotap completely (it isn't present in the regular monitor radiotap either.)

Split out ieee80211_release_reorder_frames which can then be invoked from BAR handling and other reordering code, clean up code and comments and remove function arguments that are now unused from ieee80211_sta_manage_reorder_buf().

It shouldn't be possible to get a michael MIC failure report on other frames, but it also doesn't hurt to verify. Also, since we then don't need the station struct that early, move looking it up a bit later in the RX path. Finally, while at it, a few code cleanups in the area.
