* wl12xx: Check buffer bound when processing nvs dataPontus Fuchs2012-01-121-0/+14
| | | | | | | | | | | | | | commit f6efe96edd9c41c624c8f4ddbc4930c1a2d8f1e1 upstream. An nvs with malformed contents could cause the processing of the calibration data to read beyond the end of the buffer. Prevent this from happening by adding bound checking.

* wl12xx: fix forced passive scansLuciano Coelho2011-11-111-6/+13
| | | | | | | | | | | | | | | commit 6cd9d21a0c1e2648c07c32c66bb25795ad3208aa upstream. 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.

* wl12xx: fix oops in sched_scan when forcing a passive scanLuciano Coelho2011-05-311-3/+8
| | | | | | | | | | | | | | | | Fix kernel oops when trying to use passive scheduled scans. The reason was that in passive scans there are no SSIDs, so there was a NULL pointer dereference. To solve the problem, we now check the number of SSIDs provided in the sched_scan request and only access the list if there's one or more (ie. passive scan is not forced). We also force all the channels to be passive by adding the IEEE80211_CHAN_PASSIVE_SCAN flag locally before the checks in the wl1271_scan_get_sched_scan_channels() function.

* wl12xx: add separate config value for DFS dwell time on sched scanLuciano Coelho2011-05-313-2/+9
| | | | | | | | | | | | | Use a different value for DFS dwell time when performing a scheduled scan. Previously we were using the same value as for normal passive scans. This adds some flexibility between these two different types of passive scan. For now we use 150 TUs for DFS channel dwell time. This may need to be fine-tuned in the future.

* wl12xx: fix DFS channels handling in scheduled scanLuciano Coelho2011-05-312-11/+23
| | | | | | | | | | | | | DFS channels were never getting included in the scheduled scans, because they always contain the passive flag as well and the call was asking for DFS and active channels. Fix this by ignoring the passive flag when collecting DFS channels. Also, move the DFS channels in the channel list before the 5GHz active channels (this was implemented in the FW differently than specified).

| | | | | | | | | | | | | | | | | | | | | | | | | | The FW can dynamically manage its internal TX & RX memory pools, moving blocks from one pool to another when necessary. This can significantly improve performance. Currently this feature is enabled only for 128x. Enable dynamic memory for 127x as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver stops sending TX packets when either there aren't enough memory blocks, or it runs out of TX descriptors. The driver continues to send packets to the FW only when more memory blocks are available. The FW might free TX descriptors without freeing the corresponding memory blocks, especially when dynamic memory is enabled. In cases where memory blocks are not freed at all, the driver will keep waiting for more memory blocks indefinitely.

Temporarily, the memory configuration for the 127x was used both for 127x/AP as well as 128x/AP. Since the two chips don't have the same number of memory blocks, TP was significantly degraded.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ieee80211_reconfig() sets most of the "changed" flags regardless of the actual change (e.g. BSS_CHANGED_ASSOC will be set even if the interface is still not associated). in this case the driver will issue some unneeded commands. Since the driver relies solely on the BSS_CHANGED_ASSOC flag, without checking if there was an actual change, it will end up issuing unjoin() and dummy_join() commands, although it was never associated and should just remain idle. Avoid it by checking the actual state change, in addition to the "changed" flag.
