      [SCSI] lpfc 8.2.6 : Miscellaneous Fixes · 97eab634
      由 James Smart 提交于 
      Miscellaneous Fixes
- Allow WRITE_VPARAM command when the virtual port is in a stopped state
- Fixed handling of our queue depth max that was unconditionally raising
  the depth on all vports, rather than just the vport affected.
- Fix race in interrupt handler for mailbox processing that did not take
  out the host lock.
- Removed unused functions: find_node, findnode_rpi, and fabric_abort_flogi
- Correct misspelled word unsolicited in message 0146
- Correct HW-error 5 handling - it should not reset the adapter
- Correct handling of IOCBs, which did not null out our pCmd field before
  invoking the midlayer io done function.
- Changed our maximum supported target id to 4096

      [SCSI] lpfc 8.2.6 : PCI Parity and EEH handling fixes · 9b379605
      由 James Smart 提交于 
      PCI Parity and EEH handling Fixes:
- Under a PCI Data Parity Error, remove a completion routine callback that
  was on a command that we had already failed and released.
- Under PCI parity error, we were not reinstalling the interrupt handler
  in the slot_reset callback, so we never became functional again.

      [SCSI] lpfc 8.2.6 : Multiple discovery fixes · 58da1ffb
      由 James Smart 提交于 
      Multiple Discovery Fixes:
- Fix race on discovery due to link events coinciding with vport_delete.
- Use NLP_FABRIC state to filter out switch-based pseudo initiators that
   reuse the same WWNs.
- Correct erroneous setting of DID=0 in lpfc_matchdid()
- Correct extra reference count that was in the lookup path for the
  remoteid from an unsolicited ELS.
- Correct double-free bug in els abort path.
- Correct FDMI server discovery logic for switch that return a WWN of 0.
- Fix bugs in ndlp mgmt when a node changes address
- Correct bug that did not delete RSCNs for vports upon link transitions
- Fix "0216 Link event during NS query" error which pops up when vports
  are swapped to different switch ports.
- Add sanity checks on ndlp structures
- Fix devloss log message to dump WWN correctly
- Hold off mgmt commands that were interferring with discovery mailbox cmds
- Remove unnecessary FC_ESTABLISH_LINK logic.
- Correct some race conditions in the worker thread, resulting in devloss:
  - Clear the work_port_events field before handling the work port events
  - Clear the deferred ring event before handling a deferred ring event
  - Hold the hba lock when waking up the work thread
  - Send an acc for the rscn even when we aren't going to handle it
- Fix locking behavior that was not properly protecting the ACTIVE flag,
  thus allowing mailbox command order to shift.

      [SCSI] lpfc: fix potential overflow of hbqs array · a0a74e45
      由 Jesper Juhl 提交于 
      The Coverity checker noticed that we may overrun a statically allocated
array in drivers/scsi/lpfc/lpfc_sli.c::lpfc_sli_hbqbuf_find().

The case is this; In 'struct lpfc_hba' we have

	#define LPFC_MAX_HBQS  4
	...
	struct lpfc_hba {
		...
		struct hbq_s hbqs[LPFC_MAX_HBQS];
		...
	};

But then in lpfc_sli_hbqbuf_find() we have this code

	hbqno = tag >> 16;
	if (hbqno > LPFC_MAX_HBQS)
		return NULL;

if 'hbqno' ends up as exactely 4, then we won't return, and then this

	list_for_each_entry(d_buf, &phba->hbqs[hbqno].hbq_buffer_list, list) {

will cause an overflow of the statically allocated array at index 4,
since the valid indices are only 0-3.

I propose this patch, that simply changes the 'hbqno > LPFC_MAX_HBQS'
into 'hbqno >= LPFC_MAX_HBQS' as a possible fix.

      [SCSI] lpfc: NPIV: add NPIV support on top of SLI-3 · 92d7f7b0
      由 James Smart 提交于 
      NPIV support is added to the driver.  It utilizes the interfaces of
the fc transport for the creation and deletion of vports. Within the
driver, a new Scsi_Host is created for each NPIV instance, and is
paired with a new instance of a FC port.  This allows N FC Port
elements to share a single Adapter.

      [SCSI] lpfc: NPIV: add SLI-3 interface · ed957684
      由 James Smart 提交于 
      NPIV support is only available via new adapter interface extensions,
termed SLI-3. This interface changes some of the basic behaviors such
as command and response ring element sizes and data structures, as
well as a change in buffer posting.  Note: the new firmware extensions
are found only on our mid-range and enterprise 4Gig adapters - so NPIV
support is available only on these newer adapters. The latest firmware
can be downloaded from the Emulex support page.

      [SCSI] lpfc: NPIV: split ports · 2e0fef85
      由 James Smart 提交于 
      The driver is reorganized to separate the handling of the adapter from
the handling of the FC port. Adapter handling includes submissions of
command requests, receiving responses, and managing adapter resources.
The FC port includes the discovery engine, login handling, and the
mapping of a Scsi_Host on the "port".  Although not a large functional
change, as it touches core structures and functions, resulting in a
large text delta.
