Detection of Dead IOC has been done in fault_reset_work thread. If IOC Doorbell is 0xFFFFFFFF, it will be detected as non-operation/DEAD IOC. When a DEAD IOC is detected, the code is modified to remove that IOC and all its attached devices from OS. The PCI layer API pci_remove_bus_device() is called to remove the dead IOC. Signed-off-by:

"sense_len" was declared as int type but actually it only stores a u16 value that comes from hardware. The cast to u16 in min_t() confuses static analysis because it truncates the int to u16 so I've fixed the declaration to reflect that "sense_len" is just a u16. Also there was a call to cpu_to_be16() which I've changed to be16_to_cpu(). The functions are equivalent, but obviously the hardware is big endian and we're doing the min_t() comparison on CPU endian values. This whole patch is just a cleanup and doesn't affect how the code works. Signed-off-by:

IRQF_SHARED is required for older controllers that don't support MSI(X) and which may end up sharing an interrupt. All the controllers hpsa normally supports have MSI(X) capability, but older controllers may be encountered via the hpsa_allow_any=1 module parameter. Also remove deprecated IRQF_DISABLED.

Using strlcpy instead of memcpy makes the strlen() calls superfluous and also ensures zero-termination of the copied string. At the same time get rid of the magic constant 50. Actually, I can't see why copying the callback name is necessary instead of simply storing a pointer to it (just like to the callback function itself), but that goes beyond the scope of this fix.

This patch contains minor fixes to our new logging infrastructure: - Remove extranous messages. - Re-add 'nexus' and 'hdl' information. - Adjusted the message ids to fill up the holes. - Display FCP_CMND priority on update. - Log only mail box error conditions. - Do not print "Firmware ready **** FAILED ****" if cable is unplugged. - Drop noisy 'fw_state...curr time...' message. - Correct nexus display during abort. - Add a special case error-logging set to '1'. - Catagorize I/O exception display handling. - Correct the bsg msg code printing. - Dont use dynamic logging after host is removed.

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. Call Trace: [ 69.720205] [<ffffffffa040d0d0>] bnx2i_process_new_cqes+0x290/0x3c0 [bnx2i] [ 69.804289] [<ffffffffa040d233>] bnx2i_fastpath_notification+0x33/0xa0 [bnx2 i] [ 69.891490] [<ffffffffa040d37b>] bnx2i_indicate_kcqe+0xdb/0x330 [bnx2i] [ 69.971427] [<ffffffffa03eac5e>] service_kcqes+0x16e/0x1d0 [cnic] [ 70.045132] [<ffffffffa03eacea>] cnic_service_bnx2x_kcq+0x2a/0x50 [cnic] [ 70.126105] [<ffffffffa03ead53>] cnic_service_bnx2x_bh+0x43/0x140 [cnic] [ 70.207081] [<ffffffff81060676>] tasklet_action+0x66/0x110 [ 70.273521] [<ffffffff8106025f>] __do_softirq+0xef/0x220 [ 70.337887] [<ffffffff81447ebc>] call_softirq+0x1c/0x30 This patch adds the !task->sc check and also protects the sc dereferencing under the session lock.

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. Signed-off-by: -

With open-iscsi support, target entries persisted in the FLASH were not login. Added support in the qla4xxx driver to do the login on probe time to the target entries saved in the FLASH by user. With this changes upgrade to the new kernel with open-iscsi support in qla4xxx will ensure users original target entries login on driver load Signed-off-by:

zfcp_scsi_slave_destroy erroneously always tried to finish its task even if the corresponding previous zfcp_scsi_slave_alloc returned early. This can lead to kernel page faults on accessing uninitialized fields of struct zfcp_scsi_dev in zfcp_erp_lun_shutdown_wait. Take the port field of the struct to determine if slave_alloc returned early. This zfcp bug is exposed by 4e6c82b3 (in turn fixing f7c9c6bb to be compatible with 21208ae5) which can call slave_destroy for a corresponding previous slave_alloc that did not finish. This patch is based on James Bottomley's fix suggestion in http://www.spinics.net/lists/linux-scsi/msg55449.html. Signed-off-by:
