The commit message says "Keep /proc/net/ieee80211 under the original name to avoid breaking user interface." but the thing is, it really didn't fix anything but that one create thing. It needs to fix all the other cases too. Signed-off-by: Linus Torvalds Tested-by: Randy Dunlap Signed-off-by: John W.

When ieee80211_offchannel_return is invoked as part of cancelling the scan, it doesn't bother unsetting the SDATA_STATE_OFFCHANNEL bit because it sees that the interface is down. Normally this doesn't matter because when the client STA interface is brought back up, it will probably issue a scan. But in some cases (e.g., the user changes the interface type while it is down), the SDATA_STATE_OFFCHANNEL bit will remain set. This prevents the interface queues from being started.

This bit is write only, but the driver does a read-modify-write on AR_WA without setting bit 22 in ar9002_hw_configpcipowersave() during radio disable. This causes surprise removal of hw. It can never recover from this state and the hw will become usable only after a power on/off cycle, and sometimes only during a cold reboot. This issue can be triggered by doing frequent roaming with the simple/test-roam script available from the wifi-test project [1] when roaming between APs quickly.

The kernel is supposed to trigger the authentication request in this case but this doesn't happen currently for non-SSP (pre-2.1) devices. The reason is that the authentication request happens in the remote extended features callback which never gets called for non-SSP devices. This patch fixes the issue by requesting also authentiation in the (normal) remote features callback in the case of non-SSP devices. This rule is applied only for HIGH security level which might at first seem unintuitive since on the server socket side MEDIUM is already enough for authentication. However, for the clients we really want to prefer the server side to decide the authentication requrement in most cases, and since most client sockets use MEDIUM it's better to be avoided on the kernel side for these sockets. The important socket to request it for is the dedicated bonding one and that socket uses HIGH security level. The patch is based on the initial investigation and patch proposal from Andrei Emeltchenko . Signed-off-by: Johan Hedberg Acked-by: Marcel Holtmann Signed-off-by: Gustavo F.

The change needs to be tightened with a specific 8168 version. This reverts commit 801e147cde02f04b5c2f42764cd43a89fc7400a2 ("r8169: Handle rxfifo errors on 8168 chips").
