Karan Tilak Kumar <kartilak@cisco.com> says:
Hi Martin, reviewers,
This cover letter describes the feature: add support for Fabric
Discovery and Login Services (FDLS) to fnic driver.
This functionality is needed to support port channel RSCN (PC-RSCN)
handling and serves as a base to create FC-NVME initiators
(planned later), and eCPU handling (planned later).
It is used to discover the fabric and target ports associated with the
fabric. It will then login to the target ports that are zoned to it.
The driver uses the tport structure presented by FDLS.
Port channel RSCN is a Cisco vendor specific RSCN event. It is
applicable only to Cisco UCS fabrics.
In cases where the eCPU in the UCS VIC (Unified Computing Services
Virtual Interface Card) hangs, a fabric log out is sent to the fabric.
Upon successful log out from the fabric, the IO path is failed over to
a new path.
Generally from a feature perspective, the code is divided into adding
support for this functionality initially. Then, code has been added to
modify the IO path and interfaces. Finally, support for port channel
RSCN handling has been added.
Here are the headers of some of the salient patches:
o add headers and definitions for FDLS
o add support for fabric based solicited requests and responses
o add support for target based solicited requests and responses
o add support for unsolicited requests and responses
o add support for FDMI
o add support for FIP
o add functionality in fnic to support FDLS
o modify IO path to use FDLS and tport
o modify fnic interfaces to use FDLS
o add support to handle port channel RSCN
Even though the patches have been made into a series, some patches are
heavier than others. But, every effort has been made to keep the
purpose of each patch as a single-purpose, and to compile cleanly.
All the individual patches compile cleanly. The compiler used is GCC
13.3. Some function calls have been coded as placeholders with
appropriate comments to avoid compiler warnings.
This patchset has been tested as a whole. Therefore, the tested-by
fields have been added only to one patch in the set. I've refrained
from adding tested-by to most of the patches, so as to not mislead the
reviewer/reader.
A brief note on the unit tests:
o. Perform zone in zone out testing in a loop: remove a target
port from the zone, add it to the zone in a loop. 1000+ iterations
of this test have been successful.
o. Configure multipathing, and run link flaps on single link.
IOs drop briefly, but pick up as expected.
o. Configure multipathing, and run link flaps on two links, with a
30 second delay in between. IOs drop briefly, but pick up as expected.
o. Module load/unload test.
o. Repeat the above tests with 1 queue and 64 queues.
All tests were successful.
Please consider this patch series for the next merge window.

Debugfs functions are not supposed to require error checking and, in fact,
adding checks would normally lead to the driver refusing to load when
CONFIG_DEBUGFS is disabled.
What saves us here is that this code checks for NULL instead of error
pointers so the error checking is all dead code. Delete it.

Commit 9604eea5bd3a ("scsi: st: Add third party poweron reset handling") in
v6.6 added new code to handle the Power On/Reset Unit Attention (POR UA)
sense data. This was in addition to the existing method. When this Unit
Attention is received, the driver blocks attempts to read, write and some
other operations because the reset may have rewinded the tape. Because of
the added code, also the initial POR UA resulted in blocking operations,
including those that are used to set the driver options after the device is
recognized. Also, reading and writing are refused, whereas they succeeded
before this commit.
Add code to not set pos_unknown to block operations if the POR UA is
received from the first test_ready() call after the st device has been
created. This restores the behavior before v6.6.

Add support to handle port channel RSCN.
Port channel RSCN is a Cisco vendor specific RSCN event. It is applicable
only to Cisco UCS fabrics. If there's a change in the port channel
configuration, an RCSN is sent to fnic. This is used to serially reset the
scsi initiator fnics so that there's no all paths down scenario. The
affected fnics are added to a list that are reset with a small time gap
between them.
