* [SCSI] libfc: fix statistics for FCP input/output megabytesJoe Eykholt2010-12-213-8/+12
| | | | | | | | | | | | | | | | | | | | | | The statistics for InputMegabytes and OutputMegabytes are misnamed. They're accumulating bytes, not megabytes. The statistic returned via /sys must be in megabytes, however, which is what the HBA-API wants. The FCP code needs to accumulate it in bytes and then divide by 1,000,000 (not 2^20) before it presented via sysfs. This affects fcoe.ko only, not fnic. The fnic driver correctly by accumulating bytes and then converts to megabytes. I checked that libhbalinux is using the /sys file directly without conversion. BTW, qla2xxx does divide by 2^20, which I'm not fixing here.

* [SCSI] libfcoe: reorder FCF list to put latest advertiser firstJoe Eykholt2010-12-211-0/+11
| | | | | | | | | | | | | | | | | | When there are several FCFs to choose from, the one most likely to accept a FLOGI on certian switches is the one that last answered a multicast solicit. So, when receiving an advertisement, move the FCF to the front of the list so that it gets chosen first among those with the same priority. Without this, more FLOGIs need to be sent in a test with multiple FCFs and a switch in NPV mode, but it still eventually finds one that accepts the FLOGI.

| | | | | | | | | | | | | | | Switches using multiple-FCFs may reject FLOGI in order to balance the load between multiple FCFs. Even though the FCF was available, it may have more load at the point we actually send the FLOGI. If the FLOGI fails, select a different FCF if possible, among those with the same priority. If no other FCF is available, just deliver the reject to libfc for retry.

| | | | | | | | | | | | | | | | | | Use the rport value for rec_tov for timeout values when sending fcp commands. Currently, defaults are being used which may or may not match the advertised values. The default may cause i/o to timeout on networks that set this value larger then the default value. To make the timeout more configurable in the non-REC mode we remove the FC_SCSI_ER_TIMEOUT completely allowing the scsi-ml to do the timeout. This removes an unneeded timer and allows the i/o timeout to be configured using the scsi-ml knobs.

* [SCSI] libfc: incorrect scsi host byte codes returned to scsi-mljohn fastabend2010-12-211-20/+41
| | | | | | | | | | | | | | | | | | | | | | The fcp packet recovery handler fc_fcp_recover() is called when errors occurr in a fcp session. Currently it is generically setting the status code to FC_CMD_RECOVERY for all error types. This results in DID_BUS_BUSY errors being returned to the scsi-ml. DID_BUS_BUSY errors indicate "BUS stayed busy through time out period" according to scsi.h. Many of the error reported by fc_rcp_recovery() are pkt errors. Here we update fc_fcp_recovery to use better host byte codes. With certain FAST FAIL flags set DID_BUS_BUSY and DID_ERROR will have different behaviors this was causing dm multipath to fail quickly in some cases where a retry would be a better action.

* [SCSI] libfc: Fix incorrect locking and unlocking in FCPRobert Love2010-12-211-1/+1

* [SCSI] libfc: fix NULL pointer dereference bug in fc_fcp_pkt_releaseYi Zou2010-12-211-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This happens when then tearing down the fcoe interface with active I/O. The back trace shows dead000000200200 in RAX, i.e., LIST_POISON2, indicating that the fsp is already being dequeued, which is probably why no complaining was seen in fc_fcp_destroy() about outstanding fsp not freed, since we dequeue it in the end of fc_io_compl() before releasing it. The bug is due to the fact that we have already destroyed lport's scsi_pkt_pool while on-going i/o is still accessing it through fc_fcp_pkt_release(), like this trace or the similar code path from scsi-ml to fc_eh_abort, etc. This is fixed by moving the fc_fcp_destroy() after lport is detached from scsi-ml since fc_fcp_destroy is supposed to called only once where no lport lock is taken, otherwise the fc_fcp_pkt_release() would have to grab the lport lock.

| | | | | | | | | | | | | A cid leak issue was found when the connect destroy request exceeded the driver's disconnection timeout. This will lead to a cid resource leak issue. The fix is to allow the cid cleanup even when this happens.

* [SCSI] bnx2i: Added fix for NOP-Out response panic from unsolicited NOP-InEddie Wai2010-12-213-2/+4
| | | | | | | | | | | | | | | | | | | | | The patch fixes the following situations where NOP-Out pkt is called for: - local unsolicited NOP-Out requests (requesting no NOP-In response) - local NOP-Out responses to unsolicited NOP-In requests kernel panic is observed due to double session spin_lock requests; one in the bnx2i_process_nopin_local_cmpl routine in bnx2i_hwi.c and the other in the iscsi_put_task routine in libiscsi.c The proposed fix is to export the currently static __iscsi_put_task() routine and have bnx2i call it directly instead of the iscsi_put_task() routine which holds the session spin lock.

| | | | | | | | | | | | | | | | | | Fix oops loading driver when there is direct attached SEP device The driver set max phys count to the value reported in sas iounit page zero. However this page doesn't take into account additional virutal phys. When sas topology event arrives, the phy count is larger than expected, and the driver accesses memory array beyond the end of allocated space, then oops. Manufacturing page 8 contains the info on direct attached phys. For this fix will making sure that sas topology event is not processing phys greater than the expected phy count.
