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.

Red Hat Product Errata RHEA-2016:2309 0 normal SHIPPED_LIVE RDMA stack bug fix and enhancement update 2016-11-03 13:40:45 UTC

Description Don Dutile (Red Hat) 2016-07-07 18:55:36 UTC 
Description of problem:
rpmdiff identified the following issue with libvma-8.0.1:

Report from TEST_IPV6:
[VERIFY] [libvma] usr/lib64/libvma.so.8.0.1 on aarch64 x86_64 ppc64 ppc64le uses function inet_addr, which may impact IPv6 support
[VERIFY] [libvma] usr/lib64/libvma.so.8.0.1 on aarch64 x86_64 ppc64 ppc64le uses function inet_aton, which may impact IPv6 support
[VERIFY] [libvma] usr/lib64/libvma.so.8.0.1 on aarch64 x86_64 ppc64 ppc64le uses function inet_ntoa, which may impact IPv6 support

These APIs will not work with the larger, IPv6 address (strings).

Version-Release number of selected component (if applicable):
libvma-8.0.1-2

How reproducible:
Always

Steps to Reproduce:
1. Run rpmdiff against this library, or, 
2. Run libvma  tests listed in c#25 of bz 1271624 on IPv6 net; note: must run w/unicast addrs over CX-3's; CX-4's not support atm
   (not IB net)
3.

Actual results:
sockperf w/LD_PRELOAD =libvma.so fails over IPv6 net

Expected results:
sockperf w/LD_PRELOAD =libvma.so works over IPv6 net

Additional info:
Comment 1 Don Dutile (Red Hat) 2016-07-29 19:50:22 UTC 
Update/rebase to 8.1.1 will resolve this bz, and clean up a number of coverity scan issues.
Comment 2 Don Dutile (Red Hat) 2016-08-01 15:32:28 UTC 
Rebase to 8.1.1 pushed to rhpkg repo. Build completed. Need to update errata.

Note: testing done:

mlx4<-> mlx4, roce(unicast) + ib (unicast & mcast)
 --- received two warnings when running sockperf, but the transferred occurred. Mellanox believes it could be out-of-date fw on the mlx4's(cx-3's) I used in the testing.  Hunting this issue down w/lab managers now to determine if fw issue or not.

mlx5-roce <-> mlx4-roce, unicast:  worked with no warnings on mlx5.
mlx5-ib <-> mlx[4,5]-ib will continue to fail due to bug in mlx5.

Simple, sanity testing; more complete/thorough testing should be done with sockperf, and any warnings recorded so we can pass back to MLNX to get their analysis.

Must ensure you:
echo 800 > /proc/sys/vm/nr_hugepages 
echo 10000000000 > /proc/sys/kernel/shmmax

on the client or server running with libvma.

note: libvma should work being on a client on one side, and not on server, and vice-versa.
Comment 3 Don Dutile (Red Hat) 2016-08-01 15:34:47 UTC 
Moving bz to modified as brew build has completed with rebase to 8.1.1 .
