Subject: [PATCH] ath9k: fix regression in bssidmask calculation
|
|
|
|
The commit that went into 3.17:
|
|
|
|
ath9k: Summarize hw state per channel context
|
|
|
|
Group and set hw state (opmode, primary_sta, beacon conf) per
|
|
channel context instead of whole list of vifs. This would allow
|
|
each channel context to run in different mode (STA/AP).

|
|
broke multi-vif configuration due to not properly calculating
|
|
the bssid mask.
|
|
|
|
The test case that caught this was:
|
|
|
|
create wlan0 and sta0-4 (6 total), not sure how much that matters.
|
|
associate all 6 (works fine)
|
|
disconnect 5 of them, leaving sta0 up
|
|
Start trying to bring up the other 5 one at a time. It will
|
|
fail, with iw events looking like this (in these logs, several
|
|
sta are trying to come up, but symptom is the same with just one)
|
|
|
|
The patch causing the regression made quite a few changes, but
|
|
the part I think caused this particular problem was not
|
|
recalculating the bssid mask when adding and removing interfaces.
|
|
|
|
Re-adding those calls fixes my test case. Fix bad comment
|
|
as well.
