iwl3945: fix possible il->txq NULL pointer dereference in delayed works · 210787e8

由 Stanislaw Gruszka 提交于 3月 08, 2012

On il3945_down procedure we free tx queue data and nullify il->txq
pointer. After that we drop mutex and then cancel delayed works. There
is possibility, that after drooping mutex and before the cancel, some
delayed work will start and crash while trying to send commands to
the device. For example, here is reported crash in
il3945_bg_reg_txpower_periodic():
https://bugzilla.kernel.org/show_bug.cgi?id=42766#c10

Patch fix problem by adding il->txq check on works that send commands,
hence utilize tx queue.

iwlegacy: 3945: fix hw passive scan on radar channels · 68acc4af

由 Stanislaw Gruszka 提交于 12月 23, 2011

Patch fix firmware error on "iw dev wlan0 scan passive" for
hardware scanning (with disable_hw_scan=0 module parameter).

We have disable ability to change passive scanning to active on
particular channel when traffic is detected on that channel. Otherwise
firmware will report error, when we try to do passive scan on radar
channels.
