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 Phil Sutter 2022-03-23 17:22:53 UTC 
Conntrackd in RHEL9 contains commit ff843bcb3b905 ("conntrackd: config: Do not strdup() tokens") which is problematic and fixed upstream by:

commit c12fa8df76752b0a011430f069677b52e4dad164
Author: Ash Hughes <sehguh.hsa>
Date:   Thu May 30 21:49:56 2019 +0100

    conntrackd: Use strdup in lexer

    Use strdup in the config file lexer to copy strings to yylval.string. This
    should solve the "[ERROR] unknown layer 3 protocol" problem here:
    https://www.spinics.net/lists/netfilter/msg58628.html.

This one in turn is missing, it needs to be backported.
Comment 1 Phil Sutter 2022-03-23 17:28:13 UTC 
Jiji, feel free to reassign to Yiche (he found the bug) and/or set qa_ack+ and ITM as you see fit. Thanks!
Comment 2 Phil Sutter 2022-03-25 11:25:16 UTC 
Above patch conflicts due to context changes. With the following one, it
applies cleanly. Since it is a related fix, backport it too:

    conntrackd: use strncpy() to unix path
    
    Make sure we don't go over the buffer boundary.

Yiche, please verify and set Tested:Verified field accordingly.
Comment 4 Phil Sutter 2022-03-25 18:32:16 UTC 
Requesting z-stream for RHEL9.0.0 since this is a regression from RHEL8.
Comment 7 Phil Sutter 2022-03-28 11:57:07 UTC 
Oh, sorry. I missed a follow-up from upstream:

commit b47e00e8a579519b163cb4faed017463bf64c40d
Author: Michal Kubecek <mkubecek>
Date:   Mon Jul 15 08:46:23 2019 +0200

    conntrackd: use correct max unix path length
    
    When copying value of "Path" option for unix socket, target buffer size is
    UNIX_MAX_PATH so that we must not copy more bytes than that. Also make sure
    that the path is null terminated and bail out if user provided path is too
    long rather than silently truncate it.
