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 Sven Hoexter 2015-12-15 13:40:42 UTC 
Hi,
with the switch from grep 2.6 to 2.20 grep lost the --mmap option.
I don't want to seriously argue about adding it back just for backwards
compatibility, I just could not spot that one in the release notes.

We fixed the one point where it broke something for good. :)
Comment 2 Jaroslav Škarvada 2015-12-15 14:51:06 UTC 
AFAIK the --mmap option has been deprecated since grep-2.5.4. The option was initially removed by an mistake by grep upstream, but later (IIRC in grep-2.7) the option was added back for compatibility purposes, but it do nothing. We backported this to grep-2.6.3, so the --mmap didn't cause error, but did nothing. This patch was probably mistakenly dropped during the rebase. I think it should be added back not to cause regression.
Comment 4 Sven Hoexter 2015-12-16 08:37:07 UTC 
From my point of view it's enough to just add this information to the release notes. I'd guess for most people the "damage" is already done, and they might have already fixed those occurrences like we did.

Red Hat Enterprise Linux 6 transitioned to the Production 3 Phase on May 10, 2017.  During the Production 3 Phase, Critical impact Security Advisories (RHSAs) and selected Urgent Priority Bug Fix Advisories (RHBAs) may be released as they become available.

The official life cycle policy can be reviewed here:
