RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Steve Wise 2010-04-28 14:05:38 UTC 
Description of problem: 

Down level libcxgb3 in RHEL6alpha3 breaks RDMA over Chelsio's T3 HW.  All RDMA applications fail with a FW version mismatch when trying to load the library.

Version-Release number of selected component (if applicable):

libcxgb3-1.2.1

How reproducible:

100%


Steps to Reproduce:
1. load iw_cxgb3 and configure the ethX interface accordingly
2. run: rping -s -a <ipaddr of T3 interface> -Vvd -p 9999
3.
  
Actual results:

root@helga ~]# rping -s -a 102.88.88.85 -Vvd -p 9999
port 9999
libcxgb3: Fatal firmware version mismatch. Firmware major number is 7
and libcxgb3 needs 6.
libibverbs: Warning: no userspace device-specific driver found for
/sys/class/infiniband_verbs/uverbs1
libibverbs: Warning: no userspace device-specific driver found for
/sys/class/infiniband_verbs/uverbs0
libcxgb3: Fatal firmware version mismatch. Firmware major number is 7
and libcxgb3 needs 6.
libcxgb3: Fatal firmware version mismatch. Firmware major number is 7
and libcxgb3 needs 6.
libibverbs: Warning: couldn't load driver '(null)':


Expected results:

rping server should start listening on the T3 interface for rdma connections


Additional info:


The libcxgb3 package in RHEL6 is down level.  RHEL6 needs libcxgb3-1.2.5 from here:

Comment 2 RHEL Program Management 2010-04-28 15:36:54 UTC 
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux major release.  Product Management has requested further
review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release.  This request is not yet committed for
inclusion.
Comment 3 RHEL Program Management 2010-07-15 14:52:18 UTC 
This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release. It has
been denied for the current Red Hat Enterprise Linux release.

** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **
Comment 4 Doug Ledford 2010-08-03 05:50:34 UTC 
This was resolved previously, the bug just wasn't updated.  Current rev libcxgb3 is already in rhel6.
Comment 7 releng-rhel@redhat.com 2010-11-10 21:02:28 UTC 
Red Hat Enterprise Linux 6.0 is now available and should resolve
the problem described in this bug report. This report is therefore being closed
with a resolution of CURRENTRELEASE. You may reopen this bug report if the
solution does not work for you.
