* mac80211: don't try to do anything on unchanged genIEJohannes Berg2009-05-202-2/+10
| | | | | | | | | | | | | | | | | | | 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.

* mac80211: PS processing for every Beacon with our AID in TIMJouni Malinen2009-05-201-9/+10
| | | | | | | | | | | | | | | | | 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.

* ath9k: Set PM field in frame control when in PS modeJouni Malinen2009-05-201-0/+15
| | | | | | | | | | | | | | | mac80211 does not set PM field for normal data frames, so we need to update that based on the current PS mode when using PS-Poll (timeout=0) power save mode. This allows the AP to remain in sync with our PS state. However, there is still a potential race condition between PS state changes when multiple TX queues are used and nullfunc and PS-Poll frames use different queue. That corner case may need to be handled separately by changing which queue is used either in ath9k or mac80211. Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W.

| | | | | | | | | | | | | | If we are trying to interpolate a curve with slope == 0, the return value will always be the y-coordinate. In this code we are looping until we reach a minimum y-coordinate on a line, which in the 0-slope case can never happen, thus the loop never terminates.

* cfg80211: allow wext to remove keys that don't existJohannes Berg2009-05-202-2/+10
| | | | | | | | | | | | | | | | | Some applications using wireless extensions expect to be able to remove a key that doesn't exist. One example is wpa_supplicant which doesn't actually change behaviour when running into an error while trying to do that, but it prints an error message which users interpret as wpa_supplicant having problems. The safe thing to do is not change the behaviour of wireless extensions any more, so when the driver reports -ENOENT let the wext bridge code return success to userspace. To guarantee this, also document that drivers should return -ENOENT when the key doesn't exist. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

* p54spi: use firmware/DMA bug workaround that work under hight load in p54spi_rxMax Filippov2009-05-201-8/+20
| | | | | | | | | | | | | | | | | | Under high load first data word, read after available data size is sometimes lost in p54spi_rx. It seems to depend on frequency of interrupts and latency of data read request relatively to 'data available' interrupt. The worst consequence of this bug is loss of packet transmission acknowledgement, which in turn causes overflow of tx queues and permanent link loss. Read data size and first data word in one SPI transaction. No packets from LMAC should have length less than 1 word, so this shouldn't interfere with the next read transaction.

* ath9k: Fix PS mode operation to receive buffered broadcast/multicast framesJouni Malinen2009-05-203-7/+114
| | | | | | | | | | | | | | | | | | | | | | The previous implementation was moving back to NETWORK SLEEP state immediately after receiving a Beacon frame. This means that we are unlikely to receive all the buffered broadcast/multicast frames that would be sent after DTIM Beacon frames. Fix this by parsing the Beacon frame and remaining awake, if needed, to receive the buffered broadcast/multicast frames. The last buffered frame will trigger the move back into NETWORK SLEEP state. If the last broadcast/multicast frame is not received properly (or if the AP fails to send it), the next Beacon frame will work as a backup trigger for returning into NETWORK SLEEP. A new debug type, PS (debug=0x800 module parameter), is added to make it easier to debug potential power save issues in the future. Currently, this is only used for the Beacon frame and buffered broadcast/multicast receiving. Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W.

* mac80211/cfg80211: move wiphy specific debugfs entries to cfg80211Luis R. Rodriguez2009-05-208-20/+109
| | | | | | | | | | | | | | This moves the cfg80211 specific stuff to new cfg80211 debugfs entries. Non-mac80211 will also get these entries now. There were only 4 which we take: rts_threshold fragmentation_threshold short_retry_limit long_retry_limit Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W.

* cfg80211: check allowed channel type upon userspace requestsLuis R. Rodriguez2009-05-201-22/+17
| | | | | | | | | | | | | | Thanks to nl80211 userspace can be very specific upon device configuration. Before processing the request for the new HT40 channel types (HT40- or HT40+) we need to ensure we can use them regulatory-wise. This wasn't required with wireless extensions as specifying the channel type wasn't not available and configuration was done towards the end implicitly upon association or reception of beacons from the AP. For the new nl80211 we have to check this when configuring the interfaces explicitly. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W.
