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:
run kernel selftests net/fib_rule_tests.sh failed as current iproute renamed 0x10 to lowdelay
Version-Release number of selected component (if applicable):
iproute-4.18.0-11.el8.x86_64
How reproducible:
Steps to Reproduce:
# ip rule add tos 0x10 table 100
Actual results:
# ip rule
0: from all lookup local
32765: from all tos lowdelay lookup 100
32766: from all lookup main
32767: from all lookup default
Expected results:
# ip rule
0: from all lookup local
32765: from all tos 0x10 lookup 100
32766: from all lookup main
32767: from all lookup default
Additional info:
in /etc/iproute2/rt_dsfield it shows
# Deprecated values dropped upstream
# Kept in RHEL for backwards-compatibility
0x00 default
0x10 lowdelay
0x08 throughput
0x04 reliability
# This value overlap with ECT, do not use it!
0x02 mincost
# These values seems do not want to die, Cisco likes them by a strange reason.
0x20 priority
0x40 immediate

I'm not sure if we need to keep this. Upstream commit said

update dsfield file values
Update the rt_dsfield file to contain values defined in current RFC.
The days of TOS precedence are gone, even Cisco doesn't refer
to these in the documents.
Hi Hangbin,
It was a deliberate decision to keep these outdated names, see: https://bugzilla.redhat.com/show_bug.cgi?id=1595683
Since one can't know what a user keeps in his rt_dsfield file, I guess the *real* solution to this problem is to introduce a flag which makes iproute ignore all those configs and instead print the numeric values. Maybe we could introduce '-N'/'-Numeric' flag upstream?
Cheers, Phil
