* [SCSI] scsi_transport_fc: Clear Devloss Callback Done flag in ↵James Smart2012-01-161-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | fc_remote_port_rolechg This patch fixes a bug where devloss is not called on fc_host teardown. The issue is seen if the LLDD uses rport_rolechg to add the target role to an rport. When an rport goes away, the LLDD will call fc_remote_port_delete, which will start the devloss timer. If the timer expires, the transport will call the devloss callback and set the FC_RPORT_DEVLOSS_CALLBK_DONE flag. However, the rport structure is not deleted, it is retained to store the SCSI id mappings for the rport in case it comes back. In the scenario where it does come back, and the driver calls fc_remote_port_add, but does not indicate the "target" role for the rport - the create will clear the structure, but forgets to clear FC_RPORT_DEVLOSS_CALLBK_DONE flag (which is cleared if it's added with the target role). The secondary call, of fc_remote_port_rolechg to add the target role also does not clear the flag. Thus, the next time the rport goes away, the resulting devloss timer expiration will not call the driver callback as the flag is still set. This patch adds the FC_RPORT_DEVLOSS_CALLBK_DONE flags to the list of those that are cleared upon reuse of the rport structure.

* [SCSI] bfa: Implement LUN Masking feature using the SCSI Slave Callouts.Krishna Gudipati2012-01-106-4/+112
| | | | | | | | | | | | | | | | This patch re-implements LUN Masking feature using SCSI Slave Callouts. With the new design in the slave_alloc entry point; for each new LUN discovered we check with our internal LUN Masking config whether to expose or to mask this particular LUN. We return -ENXIO (No such device or address) from slave_alloc for the LUNs we don't want to be exposed. We also notify the SCSI mid-layer to do a sequential LUN scan rather than REPORT_LUNS based scan if LUN masking is enabled on our HBA port, since a -ENXIO from any LUN in REPORT_LUNS based scan translates to a scan abort. This patch also handles the dynamic lun masking config change from enable to disable or vice-versa by resetting sdev_bflags of LUN 0 appropriately.

| | | | | | | | | | | | | | | | | | In alloc_pdu, libcxgbi tries to allocate a skb with GFP_ATOMIC, which may potentially fail. When it happens, the current code prints a warning message. When the system is under IO stress, this failure may happen lots of times and it usually scares users. Instead of printing the warning message, the code now increases the tx_dropped statistics for the ethernet interface wich is doing the iscsi task.

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes the 'mtd_writev()' function more usable and logical. We first teach it to fall-back to the 'default_mtd_writev()' function if the MTD driver does not define its own '->writev()' method. Then we make block2mtd and JFFS2 just 'mtd_writev()' instead of 'default_mtd_writev()' function. This means we can now stop exporting 'default_mtd_writev()' and instead, export 'mtd_writev()'. This is much cleaner and more logical, as well as allows us to get read of another direct 'mtd->writev' access in JFFS2.
