bugzilla for pulling in upstream libfc bug fixes and improvements to 5.5.
This request is past the original due dates for feature requests for RHEL 5.5, but I'm wondering if Mike Christie already has another bugzilla queuing up this work. Mike?
I was going to update for 5.5, but I did not have a bugzilla for it yet.
Looks like you can use this one then. Thanks Mike!

tarball of all patches
Thanks Abhijeet. Are these patches and the ones in
519091 patches you wanted in 5.5 and in 5.4.z?
Mike - I think the confusion is around if libfc is going to be re-based or not. If it is, then these patches may not be even applicable, since they are against 5.4's libfc.
So, if 5.5 isn't going to be re-based, then I would assume these patches are requested for 5.5, else - Cisco will need to test an early 5.5. with the re-based libfc to see how it impacts fnic and/or regressions.
Am I on track here, Abhijeet?
That's right Andrius.
1) We need these patches for 5.4-z. These are only libfc bug fixes and improvements to libfc disc/rport modules, and do not include any new features like FIP or NPIV.
2) If 5.5 libfc is rebased, Mike would automatically pick these patches and many other non-bug-fix patches for 5.5. from upstream libfc (like FIP support for instance)
3) If 5.5 is not rebased from upstream, then these patches would be required for 5.5 too.
We need to confirm that there is commitment to test
for the resolution of this request during the RHEL 5.5 test
phase, if it is accepted into the release.
Please post a confirmation before Oct 16th, 2009,
including the contact information for testing engineers.
yes, this would get tested as part of fnic/libfc for 5.5 after the rebase is done from upstream/open-fcoe.
Hi Mike, how is this looking for 5.5?
~~ Attention Customers and Partners - RHEL 5.5 Beta is now available on RHN ~~
RHEL 5.5 Beta has been released! There should be a fix present in this
release that addresses your request. Please test and report back results
here, by March 3rd 2010 (2010-03-03) or sooner.
Upon successful verification of this request, post your results and update
the Verified field in Bugzilla with the appropriate value.
If you encounter any issues while testing, please describe them and set
this bug into NEED_INFO. If you encounter new defects or have additional
patch(es) to request for inclusion, please clone this bug per each request
and escalate through your support representative.
Please update this bugzilla with results from testing as soon as possible. Thank you.
NetApp cert suite (NATE) was run against the RHEL 5.5 driver in non-FIP mode on UCS. All tests passed fine.
Here's a short description of the tests from our Cert Engineer:
NATE starts IO to each of the LUNs and proceeds to tune the I/O level so that it falls within NTAP guidelines (45-85% filer utilization). Once tuned, NATE proceeds through a series of fault injection steps The faults are:
Forced take-give (5)
Filer panic (5)
Filer forced reboot (5)
Filer switch port block (50)
Filer wwpn switch port block (50)
FCP down (5)
The numbers in parentheses are the iteration count of the test.
During all of these tests, DT (Disk Test) is running I/O patterns on the disks attached to the OS on the blades (or virtual machines). If DT were to see any data corruption, it would be immediately flagged as a failure. The hosts are checked that they didn't reboot during the test, nor did they lose ethernet connectivity. Also, the hosts are checked after each filer event to make sure the proper number of disk devices and paths are visible on the host.
When all totaled, NATE ran 1272 separate tests against the FC portion of Palo on RHEL-5.5.
An advisory has been issued which should help the problem
described in this bug report. This report is therefore being
closed with a resolution of ERRATA. For more information
