scsi: target: tcmu: Fix possible data corruption
When tcmu_vma_fault() gets a page successfully, before the current context
completes page fault procedure, find_free_blocks() may run and call
unmap_mapping_range() to unmap the page. Assume that when
find_free_blocks() initially completes and the previous page fault
procedure starts to run again and completes, then one truncated page has
been mapped to userspace. But note that tcmu_vma_fault() has gotten a
refcount for the page so any other subsystem won't be able to use the page
unless the userspace address is unmapped later.
If another command subsequently runs and needs to extend dbi_thresh it may
reuse the corresponding slot for the previous page in data_bitmap. Then
though we'll allocate new page for this slot in data_area, no page fault
will happen because we have a valid map and the real request's data will be
lost.
Filesystem implementations will also run into this issue but they usually
lock the page when vm_operations_struct->fault gets a page and unlock the
page after finish_fault() completes. For truncate filesystems lock pages in
truncate_inode_pages() to protect against racing wrt. page faults.
To fix this possible data corruption scenario we can apply a method similar
to the filesystems. For pages that are to be freed, tcmu_blocks_release()
locks and unlocks. Make tcmu_vma_fault() also lock found page under
cmdr_lock. At the same time, since tcmu_vma_fault() gets an extra page
refcount, tcmu_blocks_release() won't free pages if pages are in page fault
procedure, which means it is safe to call tcmu_blocks_release() before
unmap_mapping_range().
With these changes tcmu_blocks_release() will wait for all page faults to
be completed before calling unmap_mapping_range(). And later, if
unmap_mapping_range() is called, it will ensure stale mappings are removed.

scsi: core: Query VPD size before getting full page
We currently default to 255 bytes when fetching VPD pages during discovery.
However, we have had a few devices that are known to wedge if the requested
buffer exceeds a certain size. See commit
af73623f5f10 ("[SCSI] sd: Reduce
buffer size for vpd request") which works around one example of this
problem in the SCSI disk driver.
With commit
d188b0675b21 ("scsi: core: Add sysfs attributes for VPD pages
0h and 89h") we now risk triggering the same issue in the generic midlayer
code.
The problem with the ATA VPD page in particular is that the SCSI portion of
the page is trailed by 512 bytes of verbatim ATA Identify Device
information. However, not all controllers actually provide the additional
512 bytes and will lock up if one asks for more than the 64 bytes
containing the SCSI protocol fields.
Instead of picking a new, somewhat arbitrary, number of bytes for the VPD
buffer size, start fetching the 4-byte header for each page. The header
contains the size of the page as far as the device is concerned. We can use
the reported size to specify the correct allocation length when
subsequently fetching the full page.
The header validation is done by a new helper function scsi_get_vpd_size()
and both scsi_get_vpd_page() and scsi_get_vpd_buf() now rely on this to
query the page size.
In addition, scsi_get_vpd_page() is simplified to mirror the logic in
scsi_get_vpd_page(). This involves removing the Supported VPD Pages lookup
prior to attempting to query a page. There does not appear any evidence,
even in the oldest SCSI specs, that this step is required. We already rely
on scsi_get_vpd_page() throughout the stack and this function never
consulted the Supported VPD Pages. Since this has not caused any problems
it should be safe to remove the precondition from scsi_get_vpd_page().
Instrumented runs also revealed that the Supported VPD Pages lookup had
little effect since the device page index often was larger than the
supplied buffer size. As a result, inquiries frequently bypassed the index
check and went through the "If we ran off the end of the buffer, give us
the benefit of the doubt" code path which assumed the page was present
despite not being listed. The revised code takes both the page size
reported by the device as well as the size of the buffer provided by the
scsi_get_vpd_page() caller into account.

ZBC-2 allows host-managed disks to report gap zones. This allow zoned disks
to report an offset between data zone starts that is a power of two even if
the number of logical blocks with data per zone is not a power of two.
Another new feature in ZBC-2 is support for constant zone starting LBA
offsets. For zoned disks that report a constant zone starting LBA offset,
hide the gap zones from the block layer. Report the offset between data
zone starts as zone size and report the number of logical blocks with data
per zone as the zone capacity.

scsi: lpfc: Expand setting ELS_ID field in ELS_REQUEST64_WQE
ELS_ID field for ELS_REQUEST64_WQE is not filled out when FIP is not
supported by the HBA.
Move setting ELS_ID logic into __lpfc_sli_prep_els_req_rsp_s4(), and remove
ELS_ID FIP dependency logic from lpfc_sli_prep_wqe().
Introduce PLOGI ELS_ID and as a result update wqe_els_id_MASK because PLOGI
ELS_ID = 0x4 occupies up to 3 bits.
While in __lpfc_sli_prep_els_req_rsp_s4() routine, remove SLI3-isms.

scsi: lpfc: Change FA-PWWN detection methodology
Do not rely on vendor version field of the CSPs to determine if we are in a
FA-PWWN environment. Instead, use the following procedure:
First, during HBA initialization, driver does a READ_CONFIG to determine if
FA-PWWN is configured on the HBA. A LPFC_FAWWPN_CONFIG hba_flag is set
accordingly.
Next, when the link comes up before the driver gets a link up event, the
firmware logs into the fabric with FA-PWWN. If the fabric port does not
support FA-PWWN, the driver will get a Misconfigured FA-WWN async event
before the link up. A LPFC_FAWWPN_FABRIC hba_flag will be set accordingly.
Finally, if the fabric supports FA-PWWN, the firmware will replace its CSPs
WWN with the Fabric Assigned ones. Then after link up, the driver will
retrieve the Fabric Assigned WWN when it does a READ_SPARAM mbox command.

scsi: lpfc: Refactor cleanup of mailbox commands
The intention of this patch is to refactor mailbox memory allocation and
cleanup steps in one routine respectively to prevent memory leaks or memory
errors related to mailbox commands. There are trivial localized fixes as
well.
Provide lpfc_mbox_rsrc_prep() - this routine allocates the dmabuf and the
mbuf associated with it. It also catches allocation errors and returns
status.
Provide lpfc_mbox_rsrc_cleanup() - this routine verifies a dmabuf exists
and if so releases the associated mbuf and the dmabuf memory. It then sets
the ctx_buf to NULL and releases the mailbox memory to the mailbox pool.

scsi: lpfc: Fix field overload in lpfc_iocbq data structure
The lpfc_iocbq data structure has void * pointers that are overloaded to be
as many as 8 different data types and the driver translates the void * by
casting. This patch removes the void * pointers by declaring the specific
types needed by the driver. It also expands the context_un to include more
seldom used pointer types to save structure bytes. It also groups the u8
types together to pack the 8 bytes needed. This work allows the lpfc_iocbq
data structure to be more strongly typed and keeps it from being allocated
from the 512 byte slab.

scsi: lpfc: Introduce FC_RSCN_MEMENTO flag for tracking post RSCN completion
During an NVMe target reboot, the target may initialize itself as FCP only
during the first RSCN and shortly after trigger a second RSCN claiming NVMe
support. The timing of these RSCNs occur before FCP-PRLI for the first
RSCN completes leading discovery issues over NVMe.
Change RSCN and NVME-PRLI send logic based on a new FC_RSCN_MEMENTO flag
that signals when lpfc_end_rscn() is completed and serves as a memento that
discovery was started from RSCN.
