mac80211: mesh: clean up rx_bcn_presp API

2021-09-23T14:26:33+00:00

We currently pass the entire elements to the rx_bcn_presp() method, but only need mesh_config. Additionally, we use the length of the elements to calculate back the entire frame's length, but that's confusing - just pass the length of the frame instead.

mac80211: Remove invalid flag operations in mesh TSF synchronization

2016-12-13T15:22:16+00:00

mesh_sync_offset_adjust_tbtt() implements Extensible synchronization framework ([1] 13.13.2 Extensible synchronization framework). It shall not operate the flag "TBTT Adjusting subfield" ([1] 8.4.2.100.8 Mesh Capability), since it is used only for MBCA ([1] 13.13.4 Mesh beacon collision avoidance, see 13.13.4.4.3 TBTT scanning and adjustment procedures for detail). So this patch remove the flag operations. [1] IEEE Std 802.11 2012 Signed-off-by: Masashi Honma [remove adjusting_tbtt entirely, since it's now unused] Signed-off-by: Johannes Berg

mac80211: mesh: decrease max drift

2016-09-30T11:47:00+00:00

The old value was 30ms, which means mesh sync will treat any value below as merely TSF drift. This isn't really reasonable (typical drift is < 10us/s) since people probably want to adjust TSF in smaller increments (for ie. beacon collision avoidance) without mesh sync fighting back. Change max drift adjustment to 0.8ms, so manual TSF adjustments can be made in 1ms increments, with some margin. Signed-off-by: Thomas Pedersen Signed-off-by: Johannes Berg

mac80211: add offset_tsf driver op and use it for mesh

2016-09-30T11:45:44+00:00

This allows the mesh sync (and debugfs) code to make incremental TSF adjustments, avoiding any uncertainty introduced by delay in programming absolute TSF. Signed-off-by: Thomas Pedersen Signed-off-by: Johannes Berg

mac80211: move mesh related station fields to own struct

2015-07-17T13:38:06+00:00

There are now a fairly large number of mesh fields that really aren't needed in any other modes; move those into their own structure and allocate them separately. Signed-off-by: Johannes Berg

mac80211: remove BUG_ON usage

2014-04-29T15:59:27+00:00

These BUG_ON statements should never trigger, but in the unlikely event that somebody does manage don't stop everything but simply exit the code path with an error. Leave the one BUG_ON where changing it would result in a NULL pointer dereference. Signed-off-by: Johannes Berg
