If LLD has added scsi device (by calling scsi_add_device) before scheduling async scsi_scan_host then scsi_finish_async_scan() will end up calling scsi_sysfs_add_sdev for scsi device which was already added by LLD. This patch fixes this issue by skipping the call to scsi_sysfs_add_sdev() if it's already visible to rest of the kernel. Signed-off-by:

A deadlock has been reported when the completion of SCSI commands (simulated by a timer) was surprised by a module removal. This patch removes one half of the offending locks around timer deletions. This fix is applied both to stop_all_queued() which is were the deadlock was discovered and stop_queued_cmnd() which has very similar logic. This patch should be applied both to the lk 3.17 tree and Christoph's drivers-for-3.18 tree. Tested-and-reported-by:

Dan Carpenter found a issue where be2iscsi would copy the ip from userspace to the driver buffer before checking the len of the data being copied: http://marc.info/?l=linux-scsi&m=140982651504251&w=2 This patch just has us only copy what we the driver buffer can support.

The uses of "rcu_assign_pointer()" are NULLing out the pointers. According to RCU_INIT_POINTER()'s block comment: "1. This use of RCU_INIT_POINTER() is NULLing out the pointer" it is better to use it instead of rcu_assign_pointer() because it has a smaller overhead. The following Coccinelle semantic patch was used: @@ @@ - rcu_assign_pointer + RCU_INIT_POINTER (..., NULL) Signed-off-by:

Through the qla target code, the qlt_send_term_exchange() routine is used in various different places to cleanup an exchange. For the case of IOCB request queue is full, the exchange is left unhandled/ dangling. Existing code does not have re-try logic to cleanup the exchange. This patch add retry logic to cleanup the exchange before letting new commands through. For the case of FW running out of exchanges, driver need to reply SAM_STAT_BUSY to the initiators. This patch add a pending queue for the busy reply in case IOCB queue is unable to handle the cmd. Cc: <stable@vger.kernel.org> Signed-off-by:
