2011-09-28ath6kl: silence "invalid rate" warningKalle Valo4-1/+64
For some reason firmware is sending invalid rates when we try to query current bitrate from ath6kl_get_station() and a warning is issued: [ 3810.415720] ath6kl: invalid rate: 1935633515 [ 3811.105493] ath6kl: invalid rate: 1935633515 [ 3811.556063] ath6kl: invalid rate: 1935633515 As the warning happens way too often, convert the warning to a debug message once we have a proper fix. But to make it easy to follow how often the problem appears, add a debugfs to print various statistics about workarounds and make this issue the first WAR.

2011-09-28Bluetooth: Allow ACL packets over USB in HCI_RAW modePeter Hurley1-2/+1
Removed tests which prevent transmission of ACL packets when the device is in HCI_RAW mode. These tests verified that there are ACL or LE links currently tracked by the HCI connection manager. However, a HCI_RAW mode device does not use the connection manager. In these circumstances, the connection counts will be zero, and thus, transmitted ACL packets dropped. The acl_num test is actually a vestige of a previous bulk URB scheme that is no longer used by this driver (bulk URBs were not started until at least one ACL connection was created). This was incompatible with some endpoint implementations and was dropped - see commit 43c2e57f94. The utility of these tests is marginal - currently, the hci tx scheduler cannot send an ACL or LE packet for an untracked connection (except if the device is in HCI_RAW mode). Lastly, no other transport layer driver enforces these same tests.

2011-09-27wl3501_cs: min_t() cast truncates high bitsDan Carpenter1-1/+1
wrqu->encoding.length comes from the network administrator. It's size u16. We want to limit "tocopy" to the smallest value of either "len_keys", "wrqu->encoding.length" or 100. But because .length gets cast from u16 to u8 we might use a random, smaller value than the was desired. It's probably not very serious, but we may as well fix it. Btw, this is from code auditing and not from testing. I don't know if this affects anyone in real life. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: John W.

2011-09-27iwlagn: fix scan complete processingJohannes Berg2-4/+33
When we cancel a scan, the completion runs only from the workqueue. This can cause the remain-on-channel scan to fail when another one was just canceled, because we're still aborting it. To fix this, run the completion inline with the lock still held before returning from iwl_scan_cancel_timeout(). Also, to avoid the scan complete work from completing a new scan prematurely, add a new STATUS_SCAN_COMPLETE bit.

2011-09-27iwlagn: fix dangling scan requestJohannes Berg1-14/+16
If iwl_scan_initiate() fails for any reason, priv->scan_request and priv->scan_vif are left dangling. This can lead to a crash later when iwl_bg_scan_completed() tries to run a pending scan request. In practice, this seems to be very rare due to the STATUS_SCANNING check earlier. That check, however, is wrong -- it should allow a scan to be queued when a reset/roc scan is going on. When a normal scan is already going on, a new one can't be issued by mac80211, so that code can be removed completely. I introduced this bug when adding off-channel support in commit 266af4c745952e9bebf687dd68af58df553cb59d.

2011-09-27iwlagn: set the sequence control from the transport layerEmmanuel Grumbach2-3/+3
Since all the queue logic has been moved to the transport layer, the sequence number is set in the transport layer. While doing that I forgot that the mac header is copied to the TB of the TX cmd in the upper layer before the call to the transport layer. So basically we used the sequence number from mac80211... This was fine for the first assocation but after the second, mac80211 resets its counters while we don't hence a shift that led to terrible impact on performance.

In recent commit "mwifiex: use cfg80211 dynamic scan..." (7c6fa2a843..) scan table handling in driver is removed to make use of cfg80211 dynamic scan table. Now driver sends beacon buffers found in scanning directly to stack and parse the buffer for requested BSS only during association. Beacon buffer doesn't contain bss band information. Driver gets it from firmware in separate tlv (chan_band_tlv). Currently since we don't inform stack about bss bandinfo, there is an issue with 5GHz association. Use "priv" field of struct cfg80211_bss to store bandinfo. This fixes 5GHz association issue.

Sometimes association in 5GHz doesn't work. Dmesg log shows "Can not find requested SSID xyz" error message. Currently while preparing scan channel list for firmware Null entries are created for disabled channels. The routine which retrieves this list ignores channels after Null entry. Hence sometimes driver doesn't scan the channel of requested AP and association fails. The issue is fixed by avoiding those NULL entries.

2011-09-27libertas: scan behaviour consistency improvementsDaniel Drake2-17/+17
When scanning for the broadcast SSID, there is no need to add the SSID TLV (restoring the behaviour of the driver behaviour in the wext days, confirmed in Marvell specifications). If bssid is unspecified, the current scan code will usually fire off an active scan probing for the specific requested SSID. However, if a scan is ongoing (or has just finished), those scan results will be used instead (even if that scan is totally different, e.g. a passive scan on channel 4 for a different SSID). Fix this inconsistency by always firing off a scan when associating without a bssid. Signed-off-by: Daniel Drake <dsd@laptop.org> Acked-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.

Because of this ath6kl can corrupt the local TCP stack information that can result in TCP retransmission failing and TCP connections stalling. To avoid the corruption we need to copy the skb.

2011-09-23ath6kl: pass only unicast frames for aggregationKalle Valo1-7/+9
When pinging form ar6003 to the AP RTT was high even when power save was disabled: 100 packets transmitted, 97 received, 3% packet loss, time 99125ms rtt min/avg/max/mdev = 1.875/46.733/795.506/139.181 ms After some investigation one reason for this was that received multicast traffic confused the aggrecation logic and caused 400 ms timeouts when receiving multicast frames from AP. A simple way to fix is to pass only unicast frames for aggregation. This improves RTT: 100 packets transmitted, 99 received, 1% packet loss, time 99144ms rtt min/avg/max/mdev = 2.083/13.084/403.390/56.794 ms Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-09-22wl12xx: fix forced passive scansLuciano Coelho1-6/+13
We were using incorrect max and min dwell times during forced passive scans because we were still using the active scan states to scan (passively) the channels that were not marked as passive. Instead of doing passive scans in active states, we now skip active states and scan for all channels in passive states. Cc: <stable@kernel.org> # 2.6.36+ Signed-off-by: Luciano Coelho <coelho@ti.com>

2011-09-22ath6kl: Indicate the roaming capability of the firmwareVivek Natarajan1-0/+2
When the rssi of the current AP drops, both wpa_supplicant and the firmware may do a background scan to find a better AP and try to associate. This might lead to a race condition where both may try to connect to some AP based on their scan results. Since the firmware is capable of handling roaming, let wpa_supplicant know about this capability so that it will back off from bgscan based roaming.
