scsi: lpfc: PLOGI failures during NPIV testing

2017-12-25T13:20:09+00:00

[ Upstream commit e8bcf0ae4c0346fdc78ebefe0eefcaa6a6622d38 ]

Local Reject/Invalid RPI errors seen during discovery.

Temporary RPI cleanup was occurring regardless of SLI rev. It's only
necessary on SLI-4.

Adjust the test for whether cleanup is necessary.

scsi: lpfc: Fix secure firmware updates

2017-12-25T13:20:09+00:00

[ Upstream commit 184fc2b9a8bcbda9c14d0a1e7fbecfc028c7702e ]

Firmware update fails with: status x17 add_status x56 on the final write

If multiple DMA buffers are used for the download, some firmware revs
have difficulty with signatures and crcs split across the dma buffer
boundaries.  Resolve by making all writes be a single 4k page in length.

[ Upstream commit 9b3a081fb62158b50bcc90522ca2423017544367 ]

In case of connection reset Tx skb queue can have some skbs which are
not transmitted so purge Tx skb queue in release_offload_resources() to
avoid skb leak.

scsi: lpfc: Fix PT2PT PRLI reject

2017-12-25T13:20:07+00:00

[ Upstream commit a71e3cdcfce4880a4578915e110e3eaed1659765 ]

lpfc cannot establish connection with targets that send PRLI in P2P
configurations.

If lpfc rejects a PRLI that is sent from a target the target will not
resend and will reject the PRLI send from the initiator.

scsi: bfa: integer overflow in debugfs

2017-12-20T09:01:34+00:00

[ Upstream commit 3e351275655d3c84dc28abf170def9786db5176d ]

We could allocate less memory than intended because we do:

	bfad->regdata = kzalloc(len << 2, GFP_KERNEL);

The shift can overflow leading to a crash.  This is debugfs code so the
impact is very small.  I fixed the network version of this in March with
commit 13e2d5187f6b ("bna: integer overflow bug in debugfs").

Fixes: ab2a9ba189e8 ("[SCSI] bfa: add debugfs support")

if REG_VPI fails, the driver was incorrectly issuing INIT_VFI
(a SLI4 command) on a SLI3 adapter.
