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 of problem:

Provide a method to filter on network address family.

Existing SOCKADDR records are listed for any network activity. It would be helpful to be able to classify or limit records to specific network address families, such as AF_INET or AF_INET6.

An example of a network record that is unlikely to be useful and flood the logs:

type=SOCKADDR msg=audit(07/27/2017 12:18:27.019:845) : saddr={ fam=local path=/var/run/nscd/socket }
type=SYSCALL msg=audit(07/27/2017 12:18:27.019:845) : arch=x86_64 syscall=connect success=no exit=ENOENT(No such file or directory) a0=0x3 a1=0x7fff229c4980 a2=0x6e a3=0x6 items=1 ppid=3301 pid=6145 auid=sgrubb uid=sgrubb gid=sgrubb euid=sgrubb suid=sgrubb fsuid=sgrubb egid=sgrubb sgid=sgrubb fsgid=sgrubb tty=pts3 ses=4 comm=bash exe=/usr/bin/bash subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=network-test
Propose the filter field selector "AUDIT_SADDR_FAM" and command line parameter name "saddr_fam".

Upstream commit fef4978. This is covered by the rebase bz.

audit-3.0-0.11.20190507gitf58ec40.el8 was built to resolve this issue.

Steve, I do not see any mention of saddr_fam filter in auditctl man page. Don't we want to mention it?
