iwlagn: fix dangling scan request

2011-10-03T18:41:12+00:00

commit 6c80c39d9a6986a566c30d797aae37bfb697eea3 upstream. If iwl_scan_initiate() fails for any reason, priv->scan_request and priv->scan_vif are left dangling. This can lead to a crash later when iwl_bg_scan_completed() tries to run a pending scan request. In practice, this seems to be very rare due to the STATUS_SCANNING check earlier. That check, however, is wrong -- it should allow a scan to be queued when a reset/roc scan is going on. When a normal scan is already going on, a new one can't be issued by mac80211, so that code can be removed completely. I introduced this bug when adding off-channel support in commit 266af4c745952e9bebf687dd68af58df553cb59d.

iwlegacy: do not use interruptible waits

2011-10-03T18:41:12+00:00

commit 65d0f19e583e80e42b1c67c166bfc4dfdf6ab693 upstream. iwlegacy version of fix: commit effd4d9aece9184f526e6556786a94d335e38b71 Author: Johannes Berg Date: Thu Sep 15 11:46:52 2011 -0700 iwlagn: do not use interruptible waits Since the dawn of its time, iwlwifi has used interruptible waits to wait for synchronous commands and firmware loading. This leads to "interesting" bugs, because it can't actually handle the interruptions; for example when a command sending is interrupted it will assume the command completed fully, and then leave it pending, which leads to all kinds of trouble when the command finishes later. Since there's no easy way to gracefully deal with interruptions, fix the driver to not use interruptible waits. This at least fixes the error iwlagn 0000:02:00.0: Error: Response NULL in 'REPLY_SCAN_ABORT_CMD' I have seen in P2P testing, but it is likely that there are other errors caused by this.

iwlegacy: fix command queue timeout

2011-10-03T18:41:11+00:00

commit 2e2a41d6ca07d1b2aa67015c35fd80701c98e867 upstream. iwlegacy version of fix: commit 282cdb325aea4ebbc42ce753b47cc96145eb54bc Author: Johannes Berg Date: Mon Sep 12 12:09:10 2011 -0700 iwlagn: fix command queue timeout If the command queue is constantly busy, which can happen in P2P, the hangcheck timer will frequently find a command in it and will eventually reset the device because nothing sets the timestamp for this queue when commands are processed. Fix this by setting the timestamp when a command completes. iwlegacy does not support P2P, but this patch fix possible unneeded hardware resets, hence is needed.

libsas: fix failure to revalidate domain for anything but the first expander child.

2011-10-03T18:41:10+00:00

commit 24926dadc41cc566e974022b0e66231b82c6375f upstream. In an enclosure model where there are chaining expanders to a large body of storage, it was discovered that libsas, responding to a broadcast event change, would only revalidate the domain of first child expander in the list. The issue is that the pointer value to the discovered source device was used to break out of the loop, rather than the content of the pointer. This still remains non-compliant as the revalidate domain code is supposed to loop through all child expanders, and not stop at the first one it finds that reports a change count. However, the design of this routine does not allow multiple device discoveries and that would be a more complicated set of patches reserved for another day. We are fixing the glaring bug rather than refactoring the code. Signed-off-by: Mark Salyzyn Signed-off-by: James Bottomley Signed-off-by: Greg Kroah-Hartman
