2017-10-23scsi: Suppress a kernel warning in case the prep function returns BLKPREP_DEFERBart Van Assche
The legacy block layer handles requests as follows: - If the prep function returns BLKPREP_OK, let blk_peek_request() return the pointer to that request. - If the prep function returns BLKPREP_DEFER, keep the RQF_STARTED flag and retry calling the prep function later. - If the prep function returns BLKPREP_KILL or BLKPREP_INVALID, end the request. In none of these cases it is correct to clear the SCMD_INITIALIZED flag from inside scsi_prep_fn(). Since scsi_prep_fn() already guarantees that scsi_init_command() will be called once even if scsi_prep_fn() is called multiple times, remove the code that clears SCMD_INITIALIZED from scsi_prep_fn(). The scsi-mq code handles requests as follows: - If scsi_mq_prep_fn() returns BLKPREP_OK, set the RQF_DONTPREP flag and submit the request to the SCSI LLD. - If scsi_mq_prep_fn() returns BLKPREP_DEFER, call blk_mq_delay_run_hw_queue() and return BLK_STS_RESOURCE. - If the prep function returns BLKPREP_KILL or BLKPREP_INVALID, call scsi_mq_uninit_cmd() and let the blk-mq core end the request. In none of these cases scsi_mq_prep_fn() should clear the SCMD_INITIALIZED flag. Hence remove the code from scsi_mq_prep_fn() function that clears that flag. This patch avoids that the following warning is triggered when using the legacy block layer: ------------[ cut here ]------------ WARNING: CPU: 1 PID: 4198 at drivers/scsi/scsi_lib.c:654 scsi_end_request+0x1de/0x220 CPU: 1 PID: 4198 Comm: mkfs.f2fs Not tainted 4.14.0-rc5+ #1 task: ffff91c147a4b800 task.stack: ffffb282c37b8000 RIP: 0010:scsi_end_request+0x1de/0x220 Call Trace: <IRQ> scsi_io_completion+0x204/0x5e0 scsi_finish_command+0xce/0xe0 scsi_softirq_done+0x126/0x130 blk_done_softirq+0x6e/0x80 __do_softirq+0xcf/0x2a8 irq_exit+0xab/0xb0 do_IRQ+0x7b/0xc0 common_interrupt+0x90/0x90 </IRQ> RIP: 0010:_raw_spin_unlock_irqrestore+0x9/0x10 __test_set_page_writeback+0xc7/0x2c0 __block_write_full_page+0x158/0x3b0 block_write_full_page+0xc4/0xd0 blkdev_writepage+0x13/0x20 __writepage+0x12/0x40 write_cache_pages+0x204/0x500 generic_writepages+0x48/0x70 blkdev_writepages+0x9/0x10 do_writepages+0x34/0xc0 __filemap_fdatawrite_range+0x6c/0x90 file_write_and_wait_range+0x31/0x90 blkdev_fsync+0x16/0x40 vfs_fsync_range+0x44/0xa0 do_fsync+0x38/0x60 SyS_fsync+0xb/0x10 entry_SYSCALL_64_fastpath+0x13/0x94 ---[ end trace 86e8ef85a4a6c1d1 ]--- Fixes: commit 64104f703212 ("scsi: Call scsi_initialize_rq() for filesystem requests") Signed-off-by: Bart Van Assche <bart.vanassche@wdc.com> Cc: Damien Le Moal <damien.lemoal@wdc.com> Cc: Christoph Hellwig <hch@lst.de> Cc: Hannes Reinecke <hare@suse.com> Cc: Johannes Thumshirn <jthumshirn@suse.de> Reviewed-by: Damien Le Moal <damien.lemoal@wdc.com> Reviewed-by: Johannes Thumshirn <jthumshirn@suse.de> Signed-off-by: Martin K.

2017-10-22Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/netDavid S. Miller
There were quite a few overlapping sets of changes here. Daniel's bug fix for off-by-ones in the new BPF branch instructions, along with the added allowances for "data_end > ptr + x" forms collided with the metadata additions. Along with those three changes came veritifer test cases, which in their final form I tried to group together properly. If I had just trimmed GIT's conflict tags as-is, this would have split up the meta tests unnecessarily. In the socketmap code, a set of preemption disabling changes overlapped with the rename of bpf_compute_data_end() to bpf_compute_data_pointers(). Changes were made to the mv88e6060.c driver set addr method which got removed in net-next. The hyperv transport socket layer had a locking change in 'net' which overlapped with a change of socket state macro usage in 'net-next'. Signed-off-by: David S. Miller <davem@davemloft.net>

2017-10-18scsi: scsi_error: Handle power-on reset unit attentionHannes Reinecke
As per SAM there is a status precedence, with any sense code 29/XX taking second place just after an ACA ACTIVE status. Additionally, each target might prefer to not queue any unit attention conditions, but just report one. Due to the above, this will be that one with the highest precedence. This results in the sense code 29/XX effectively overwriting any other unit attention. Hence we should report the power-on reset to userland so that it can take appropriate action.

2017-10-16scsi: qla2xxx: Allow MBC_GET_PORT_DATABASE to query and save the port statesDuane Grigsby
The MBC_GET_PORT_DATABASE command normally checks the port state information. This patch allows it to save that info in the fcport structure and ignore the check if the query flag is set.

2017-10-16scsi: lpfc: Fix a precedence bug in lpfc_nvme_io_cmd_wqe_cmpl()Dan Carpenter
The ! has higher precedence than the & operation. I've added parenthesis so this works as intended. Fixes: 952c303b329c ("scsi: lpfc: Ensure io aborts interlocked with the target.")

2017-10-16scsi: aic7xxx: make a couple of functions staticColin Ian King
Functions ahc_devlimited_syncrate and ahc_linux_initialize_scsi_bus are declared static in their prototypes but are missing in their definitions, so add the missing static. Cleans up sparse warnings: symbol 'ahc_devlimited_syncrate' was not declared. Should it be static? symbol 'ahc_linux_initialize_scsi_bus' was not declared. Should it be static?
