* mac80211: improve scan timingJohannes Berg2009-05-111-8/+23
| | | | | | | | | | | | | | | | | | | | | The call to ieee80211_hw_config() is supposed to apply changes synchronously, so once it returns the parameters are applied to the hardware. Thus, there really is no need to delay the probing by the channel switch time again since the channel switch has already happened once we get to this code. Additionally, there is no need to wait for a NAV update (probe delay) when the channel is passively scanned. Remove that extra time too. This cuts scanning time from over 7 seconds to under 4 on ar9170, which is due to the number of channels scanned and ar9170's switch time being advertised as 135ms (my test now indicates it is about 77ms with the current driver, but the difference might also be due to using a different machine with different USB controllers).

* mac80211: MFP - Drop unprotected Action frames prior key setupJouni Malinen2009-05-111-9/+19
| | | | | | | | | | | | | | | | | When management frame protection (IEEE 802.11w) is used, unprotected Robust Action frames are not allowed prior to key configuration. However, unprotected Deauthentication and Disassociation frames are allowed at that point, but not after key configuration. Make ieee80211_drop_unencrypted() handle the special cases for MFP by separating the basic Data frame case from Management frame processing and handle the Management frames only if MFP has been negotiated. In addition, do not use sdata->drop_unencrypted for Management frames since the decision on whether to accept the frame depends on the key being configured.

* mac80211: Drop unencrypted frames based on key setupJouni Malinen2009-05-111-9/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using nl80211, we do not have a mechanism to set sdata->drop_unencrypted. Currently, this breaks code that is supposed to drop unencrypted frames when protection is expected since ieee80211_rx_h_decrypt() is optimized to not set rx->key when the frame is not protected. This patch modifies ieee80211_rx_h_decrypt() to set rx->key for all frames and only skip decryption if the frame is not protected. This allows ieee80211_drop_unencrypted() to correctly drop frames even if drop_unencrypted is not set. The changes here are not enough to handle all cases, though. Additional patches will be needed to implement proper IEEE 802.1X PAE for station mode (currently, this is only used for AP mode) and some additional rules are needed for MFP to drop unprotected Robust Action frames prior to having PTK and IGTK configured. In theory, the unprotected frames could and should be dropped in ieee80211_rx_h_decrypt(). However, due to the special case with EAPOL frames that have to be allowed to be received unprotected even when keys are set, it is simpler to only set rx->key and allow the ieee80211_frame_allowed() function to handle the actual dropping of data frames after 802.11->802.3 header conversion. In addition, unprotected robust management frames are dropped before they are processed. Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W.

* cfg80211: fix wext iw_freq parsingJohannes Berg2009-05-111-6/+18
| | | | | | | | | | | | | | | | | The function to parse a struct iw_freq has a stupid bug, it returns NULL when the channel cannot be found at all, but NULL is supposed to mean "auto". Fix this by checking the return value of ieee80211_get_channel() and returning ERR_PTR(-EINVAL) if it returned NULL (channel not found). This fixes an issue where you could say (in IBSS mode) iwconfig wlan0 channel 21 and it would use channel 1 instead because that's the first available channel with IBSS allowed (which is what the "auto" setting uses).

* mac80211: set default QoS values according to specJohannes Berg2009-05-112-12/+52
| | | | | | | | | | | We've never really cared about the default QoS (WMM) values, but we really should if the AP doesn't send any. This patch makes mac80211 use the default values according to 802.11-2007, and additionally syncs the default values when we disassociate so whatever the last AP said gets "unconfigured".

* mac80211: fix scan channel raceJohannes Berg2009-05-113-7/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a software scan starts, it first sets sw_scanning, but leaves the scan_channel "unset" (it currently actually gets initialised to a default). Now, when something else tries to (re)configure the hardware in the window between these two events (after sw_scanning = true, but before scan_channel is set), the current code switches to the (unset!) scan_channel. This causes trouble, especially when switching bands and sending frames on the wrong channel. To work around this, leave scan_channel initialised to NULL and use it to determine whether or not a switch to a different channel should occur (and also use the same condition to check whether to adjust power for scan or not). Additionally, avoid reconfiguring the hardware completely when recalculating idle resulted in no changes, this was the problem that originally led us to discover the race condition in the first place, which was helpfully bisected by Pavel. This part of the patch should not be necessary with the other fixes, but not calling the ieee80211_hw_config function when we know it to be unnecessary is certainly a correct thing to do. Unfortunately, this patch cannot and does not fix the race condition completely, but due to the way the scan code is structured it makes the particular problem Pavel discovered (race while changing channel at the same time as transmitting frames) go away. To fix it completely, more work especially with locking configuration is needed.

* nl80211 : Add support for configuring MFPJouni Malinen2009-05-114-0/+39
| | | | | | | | | | | | | | | | | NL80211_CMD_ASSOCIATE request must be able to indicate whether management frame protection (IEEE 802.11w) is being used. mac80211 was able to use MFP in client mode only with WEXT, but the new NL80211_ATTR_USE_MFP attribute will allow this to be done with nl80211, too. Since we are currently using nl80211 for MFP only with drivers that use user space SME, only MFP disabled and required values are used. However, the NL80211_ATTR_USE_MFP attribute is an enum that can be extended with MFP optional in the future, if that is needed with some drivers (e.g., if the RSN IE is generated by the driver).

| * mac80211: Add a timeout for frames in the RX reorder bufferJouni Malinen2009-05-063-2/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows skbs to be released from the RX reorder buffer in case they have been there for an unexpectedly long time without us having received the missing frames before them. Previously, these frames were only released when the reorder window moved and that could take very long time unless new frames were received constantly (e.g., TCP connections could be killed more or less indefinitely). This situation should not happen very frequently, but it looks like there are some scenarious that trigger it for some reason. As such, this should be considered mostly a workaround to speed up recovery from unexpected siutation that could result in connections hanging for long periods of time. The changes here will only check for timeout situation when adding new RX frames to the reorder buffer. It does not handle all possible cases, but seems to help for most cases that could result from common network usage (e.g., TCP retrying at least couple of times). For more completely coverage, a timer could be used to periodically check whether there are any frames remaining in the reorder buffer if no new frames are received.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add code to support the various antenna scenarios supported by hw * For now hardcode the default scenario (single or dual omnis with tx/rx diversity working and tx antenna handled by session -hw keeps track on which antenna it got ack from each ap/station and maps each ap/station to one of the antennas-).

| * ath5k: Enable AP modeJiri Slaby2009-05-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After some debuging we were hitting the following bugs so far... * Due to huge channel list hostapd couldn't get infos from the driver and couldn't set the channel. If we manualy set the channel after hostapd starts (by setting channel to 0 -auto), beacons are sent but they wont show up on scan because they are malformed (they have channel = 0 because hostapd doesn't update the channel info -this is probably a hostapd bug so i'm CCing Jouni) and they get dropped. Bob fixed this by only allowing standard channels to be registered so now hostapd works as expected. * Docs (and HAL source) say that we must write 0 on timer0 when operating on AP mode to start TSF increment but this seems to mess with DBA in many cases and beacon queue never gets started. We fixed that on the previous patch. We have some more things to deal with... * For some reason (hw bug or something else) after restarting hostapd a few times, beacon inteval seems to change from 100ms to a sec (we get one beacon per sec). * We need to set sleep timers on STA mode and enable power saving + support PCF. ...but i think it's time we enable AP support "officialy" so that we can get more feedback from users. I ran ath5k with the mentioned patches + hostapd 0.6.8 and AP mode worked fine (it had some less throughput on my tests than IBSS but it worked).

Docs say that we must write 0 on this register on AP mode to start TSF increment, we do both to be on the safe side. * Fix num_tx_pending function, we never read the register :P that's why we got all those "beacon queue 7 didn't stop messages". * Put full prioriy on beacon queue, lock all queues with lower priority using the arblock and also bypass any arblock by seting the arblock ignore flag. * For the CAB queue (do we need this thing ?, it seems crap) since it's supposed to fire up after each beacon (we don't use it on driver part, ath9k/MadWiFi does), don't make it DBA gated but instead make it fire after each beacon by using the beacon sent gated flag. * Increase bmiss threshold to 10, that's what we used on MadWiFi for a long time. Also when we have pending frames on the beacon queue (we got a beacon that didn't make it on the air) it's more likely that the beacon queue never started, probably due to faulty DBA setting, so change that "beacon queue didn't stop" message. Tested this with AP mode and IBSS mode and seems to work fine ;-) Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Now that we have regulatory control enable the driver to set txpower on hw * Also use txpower table offset so that we can match power range set by user/driver with indices on power table. Tested 2 different cards (a CM9 and an RF5112-based ubnt) and got the same output using a remote machine to measure per-packet rssi (conected the cards using attenuators). I also switched between various tx power levels and i saw an equal power change on the remote machine (so txpower changes as expected) and verified that we have the same output on each rate.
