Commit 659743b0 "[SCSI] libiscsi: Reduce locking contention in fast path" introduced a new smatch warning on libiscsi.c "iscsi_xmit_task() warn: inconsistent returns bottom_half:: locked (1410 [(-61)]) unlocked (1425 [0], 1425 [s32min-(-1),1-s32max])", which we can eliminate by using non bh locking on the nested spin_lock call.

Fnic Ctlr Path Trace utility is a tracing functionality built directly into fnic driver to trace the control path frames like discovery, FLOGI request/reply, PLOGI request/reply, link event etc. It will be one trace file for all fnics. It will help us to debug and resolve the discovery and initialization related issues in more convenient way. This trace information includes time stamp, Host Number, Frame type, Frame Length and Frame. By default,64 pages are allocated but we can change the number of allocated pages by module parameter fnic_fc_trace_max_page. Each entry is of 256 byte and available entries are depends on allocated number of pages. We can turn on or off the fnic control path trace functionality by module paramter fc_trace_enable and/or reset the trace contain by module paramter fc_trace_clear. Signed-off-by:

In fnic abort handler, abort queuing can be failed when hardware queue is full. The command state is left as abort queued. The command with abort queued state will never be queued next time for abort or termiantion. Fix restores the command state in above case. Signed-off-by:

This patch contains following three minor fixes. 1) During Probe, fnic was sending FIP solicitation in Non FIP mode which is not expected, setting the internal fip state to Non FIP mode explicitly, avoids sending FIP frame. 2) When target goes offline, all outstanding IOs belong to the target will be terminated by driver, If the termination count is high, then it influences firmware responsiveness. To improve the responsiveness, default IO throttle count is reduced to 256. 3) Accessing Virtual Fabric Id (vfid) and fc_map of Fibre-Channel Forwarder(FCF) is invalid in fnic driver when Clear Virtual Link(CVL) is received prior to receiving flogi reject from switch. As CVL clears all FCFs. Signed-off-by:

This can block progress of the SCSI error handler thread and cause long I/O outages. Instead just fail immediately if another reset is going on or we are accessing flash memory. Signed-off-by:

Attempting to do any logins from the SCSI reset handler can lead to a deadlock scenario if a rport times out and the FC transport layer. Move doing any port logins to the DPC thread so as not to impede the progress of the SCSI error handler thread and avoid deadlock situations. Signed-off-by:

Fix double free problem within qla2xxx driver where current code prematurely free qla_tgt_cmd while firmware still has the command. When firmware release the command after abort, the code attempt a second free as part of command completion processing. When TCM start the free process, NULL pointer was hit. ------ WARNING: CPU: 8 PID: 43613 at lib/list_debug.c:62 __list_del_entry+0x82/0xd0() list_del corruption. next->prev should be ffff88082b5cfb08, but was 6b6b6b6b6b6b6b6b CPU: 8 PID: 43613 Comm: kworker/8:0 Tainted: GF W O 3.13.0-rc3-nab_t10dif+ #6 Hardware name: HP ProLiant DL380p Gen8, BIOS P70 08/20/2012 Workqueue: events cache_reap 000000000000003e ffff88081b2e3c78 ffffffff815a051f 000000000000003e ffff88081b2e3cc8 ffff88081b2e3cb8 ffffffff8104fc2c 0000000000000000 ffff88082b5cfb00 ffff88081c788d00 ffff88082b5d7200 ffff88082b5d3080 Call Trace: [<ffffffff815a051f>] dump_stack+0x49/0x62 [<ffffffff8104fc2c>] warn_slowpath_common+0x8c/0xc0 [<ffffffff8104fd16>] warn_slowpath_fmt+0x46/0x50 [<ffffffff812b6592>] __list_del_entry+0x82/0xd0 [<ffffffff8106d48c>] process_one_work+0x12c/0x510 [<ffffffff8106d4d3>] ? process_one_work+0x173/0x510 [<ffffffff8106ebdf>] worker_thread+0x11f/0x3a0 [<ffffffff8106eac0>] ? manage_workers+0x170/0x170 [<ffffffff81074f26>] kthread+0xf6/0x120 [<ffffffff8109f103>] ? __lock_release+0x133/0x1b0 [<ffffffff81074e30>] ? __init_kthread_worker+0x70/0x70 [<ffffffff815aec2c>] ret_from_fork+0x7c/0xb0 [<ffffffff81074e30>] ? __init_kthread_worker+0x70/0x70 ---[ end trace dfc05c3f7caf8ebe ]--- BUG: unable to handle kernel NULL pointer dereference at 0000000000000008 IP: [<ffffffff8106d391>] process_one_work+0x31/0x510 ------- Signed-off-by:
