2011-12-14[SCSI] bnx2i: Fixed kernel panic caused by unprotected task->sc->request derefEddie Wai1-2/+3
During session recovery, the conn_stop call will trigger a flush to all outstanding SCSI cmds in the xmit queue. This will set all outstanding task->sc to NULL prior to the session_teardown call which frees the task memory. In the bnx2i SCSI response processing path, only the task was being checked for NULL under the session lock before the task->sc->request dereferencing. If there are outstanding SCSI cmd responses pending for process, the following kernel panic can be exposed where task->sc was found to be NULL.

2011-12-14[SCSI] qla4xxx: a small loop fixTomas Henzl1-1/+3
When the qla4xxx_get_fwddb_entry returns QLA_ERROR the nex_idx is not updated, for (idx = 0; idx < max_ddbs; idx = next_idx) { ret = qla4xxx_get_fwddb_entry(ha, idx, NULL, 0, NULL, &next_idx, &state, &conn_err, NULL, NULL); if (ret == QLA_ERROR) continue; This means there is a risk that the 'idx < max_ddbs' condition will never met and the loop will loop forever. Fix this by explicitly increasing the next_idx in the error condition. Maybe a break instead of continue is more appropriate, leaving the decision on the qlogic maintainer.

2011-12-14block: misc updates to blk_get_queue()Tejun Heo1-1/+1
* blk_get_queue() is peculiar in that it returns 0 on success and 1 on failure instead of 0 / -errno or boolean. Update it such that it returns %true on success and %false on failure. * Make sure the caller checks for the return value. * Separate out __blk_get_queue() which doesn't check whether @q is dead and put it in blk.h.

The bus reset used to wait for 5 minutes for the loop and upper layer callers used to hang and give stack trace because of getting stuck for 120 sec.

2011-11-11[SCSI] aacraid: controller hangs if kernel uses non-default ASPM policyVasily Averin1-0/+4
Aacraid controller can hang on some nodes if kernel uses non-default (powersave) ASPM policy. Controller hangs shortly after successful load and hardware detection. Scsi error handler detects this hang and tries to restart hardware but it does not help. Initially it was noticed on RHEL6-based openVZ kernel after backporting aacraid driver from mainline (RHEL6 kernel with original driver works well) http://bugzilla.openvz.org/show_bug.cgi?id=2043 This issue happens because default ASPM policy was changed in Red Hat kernels. Therefore guys from Red Hat have noticed this problem long time ago: on Fedora 12 https://bugzilla.redhat.com/show_bug.cgi?id=540478 on Fedora 14 https://bugzilla.redhat.com/show_bug.cgi?id=679385 In RHEL6 kernel this issue was fixed, ASPM was disabled in aacraid driver. In kernel changelog I've found that seems it was done by Matthew Garrett: - [scsi] aacraid: Disable ASPM by default (Matthew Garrett) [599735] However seems this patch was not submitted to mainline. I've reproduced this issue on vanilla 3.1.0 kernel booted with "pcie_aspm.policy=powersave" option, So I believe it makes sense to do it now.

2011-11-09[SCSI] Silencing 'killing requests for dead queue'Hannes Reinecke1-1/+2
When we tear down a device we try to flush all outstanding commands in scsi_free_queue(). However the check in scsi_request_fn() is imperfect as it only signals that we _might start_ aborting commands, not that we've actually aborted some. So move the printk inside the scsi_kill_request function, this will also give us a hint about which commands are aborted.
