If a SES device returns an error on a requested diagnostic page, we are currently printing an error indicating the wrong page was received. Fix this up to simply return a failure and only check the returned page when the diagnostic page buffer was populated by the device. Signed-off-by:

Fixes the following lockdep warning that can occur when scsi-mq is enabled with ipr due to ipr calling scsi_unblock_requests from irq context. The fix is to move the call to scsi_unblock_requests to ipr's existing workqueue. stack backtrace: CPU: 28 PID: 0 Comm: swapper/28 Not tainted 4.13.0-rc2-gcc6x-gf74c89bd #1 Call Trace: [c000001fffe97550] [c000000000b50818] dump_stack+0xe8/0x160 (unreliable) [c000001fffe97590] [c0000000001586d0] print_usage_bug+0x2d0/0x390 [c000001fffe97640] [c000000000158f34] mark_lock+0x7a4/0x8e0 [c000001fffe976f0] [c00000000015a000] __lock_acquire+0x6a0/0x1a70 [c000001fffe97860] [c00000000015befc] lock_acquire+0xec/0x2e0 [c000001fffe97930] [c000000000b71514] _raw_spin_lock+0x44/0x70 [c000001fffe97960] [c0000000005b60f4] blk_mq_sched_dispatch_requests+0xa4/0x2a0 [c000001fffe979c0] [c0000000005acac0] __blk_mq_run_hw_queue+0x100/0x2c0 [c000001fffe97a00] [c0000000005ad478] __blk_mq_delay_run_hw_queue+0x118/0x130 [c000001fffe97a40] [c0000000005ad61c] blk_mq_start_hw_queues+0x6c/0xa0 [c000001fffe97a80] [c000000000797aac] scsi_kick_queue+0x2c/0x60 [c000001fffe97aa0] [c000000000797cf0] scsi_run_queue+0x210/0x360 [c000001fffe97b10] [c00000000079b888] scsi_run_host_queues+0x48/0x80 [c000001fffe97b40] [c0000000007b6090] ipr_ioa_bringdown_done+0x70/0x1e0 [c000001fffe97bc0] [c0000000007bc860] ipr_reset_ioa_job+0x80/0xf0 [c000001fffe97bf0] [c0000000007b4d50] ipr_reset_timer_done+0xd0/0x100 [c000001fffe97c30] [c0000000001937bc] call_timer_fn+0xdc/0x4b0 [c000001fffe97cf0] [c000000000193d08] expire_timers+0x178/0x330 [c000001fffe97d60] [c0000000001940c8] run_timer_softirq+0xb8/0x120 [c000001fffe97de0] [c000000000b726a8] __do_softirq+0x168/0x6d8 [c000001fffe97ef0] [c0000000000df2c8] irq_exit+0x108/0x150 [c000001fffe97f10] [c000000000017bf4] __do_irq+0x2a4/0x4a0 [c000001fffe97f90] [c00000000002da50] call_do_irq+0x14/0x24 [c0000007fad93aa0] [c000000000017e8c] do_IRQ+0x9c/0x140 [c0000007fad93af0] [c000000000008b98] hardware_interrupt_common+0x138/0x140 Reported-by:

Don't make any assumptions on the sg_io_hdr_t::dxfer_direction or the sg_io_hdr_t::dxferp in order to determine if it is a valid request. The only way we can check for bad requests is by checking if the length exceeds 256M. Signed-off-by:

The CPU hotplug related code of this driver can be simplified by: 1) Consolidating the callbacks into a single state. The CPU thread can be torn down on the CPU which goes offline. There is no point in delaying that to the CPU dead state 2) Let the core code invoke the online/offline callbacks and remove the extra for_each_online_cpu() loops. Signed-off-by:

The BNX2I module init/exit code installs/removes the hotplug callbacks with the cpu hotplug lock held. This worked with the old CPU locking implementation which allowed recursive locking, but with the new percpu rwsem based mechanism this is not longer allowed. Use the _cpuslocked() variants to fix this. Reported-by:

bnx2fc_process_new_cqes() has protection against CPU hotplug, which relies on the per cpu thread pointer. This protection is racy because it happens only partially with the per cpu fp_work_lock held. If the CPU is unplugged after the lock is dropped, the wakeup code can dereference a NULL pointer or access freed and potentially reused memory. Restructure the code so the thread check and wakeup happens with the fp_work_lock held. Signed-off-by:

When LPFC is built-in but NVMe is a loadable module, we fail to link the kernel: drivers/scsi/built-in.o: In function `lpfc_nvme_create_localport': (.text+0x156a82): undefined reference to `nvme_fc_register_localport' drivers/scsi/built-in.o: In function `lpfc_nvme_destroy_localport': (.text+0x156eaa): undefined reference to `nvme_fc_unregister_remoteport' We can avoid this either by forcing lpfc to be a module, or by disabling NVMe support in this case.

This patch adds support for Boot from SAN over iSCSI offload. The iSCSI boot information in the NVRAM is populated under /sys/firmware/iscsi_bootX/ using qed NVM-image reading API and further exported to open-iscsi to perform iSCSI login enabling boot over offload iSCSI interface in a Boot from SAN environment.
