Subject: [GIT PULL] SCSI fixes for 4.12-rc4
This is a set of user visible fixes (excepting one format string
change). Four of the qla2xxx fixes only affect the firmware dump path,
but it's still important to the enterprise. The rest are various NULL
pointer crash conditions or outright driver hangs.
The patch is available here:
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes
The short changelog is:
Arnd Bergmann (1):
scsi: lpfc: nvmet_fc: fix format string
Bill Kuzeja (1):
scsi: qla2xxx: Fix extraneous ref on sp's after adapter break
Guilherme G. Piccoli (1):
scsi: lpfc: Avoid NULL pointer dereference in lpfc_els_abort()
Gustavo A. R. Silva (1):
scsi: lpfc: prevent potential null pointer dereference
Joe Carnuccio (4):
scsi: qla2xxx: Fix crash due to NULL pointer dereference of ctx
scsi: qla2xxx: Fix mailbox pointer error in fwdump capture
scsi: qla2xxx: Set bit 15 for DIAG_ECHO_TEST MBC
scsi: qla2xxx: Modify T262 FW dump template to specify same start/end to debug customer issues
Johannes Thumshirn (1):
scsi: qla2xxx: don't disable a not previously enabled PCI device
Martin K. Petersen (1):
scsi: scsi_debug: Avoid PI being disabled when TPGS is enabled
Maurizio Lombardi (1):
scsi: bnx2fc: fix race condition in bnx2fc_get_host_stats()
Quinn Tran (1):
scsi: qla2xxx: Fix NULL pointer access due to redundant fc_host_port_name call
Sawan Chandak (1):
scsi: qla2xxx: Fix crash due to mismatch mumber of Q-pair creation for Multi queue
Varun Prakash (1):
scsi: cxgb4i: libcxgbi: in error case RST tcp conn
himanshu.madhani@...ium.com (1):
scsi: qla2xxx: Fix recursive loop during target mode configuration for ISP25XX leaving system unresponsive
