3 | util-linux       | package | (any)      | poo#119008, kernel regression boo#1202138

For #131249 we maybe already applied an approach that worked for us which we should apply here, I guess?

On petrol now I ran zypper patch --dry-run manually and sequentially added patches to the package locks as well ending up with

zypper al -t patch -m "poo#119008, kernel regression boo#1202138" openSUSE-SLE-15.5-2023-4375
zypper al -t patch -m "poo#119008, kernel regression boo#1202138" openSUSE-SLE-15.5-2023-4071
zypper al -t patch -m "poo#119008, kernel regression boo#1202138" openSUSE-SLE-15.5-2023-3971
zypper al -t patch -m "poo#119008, kernel regression boo#1202138" openSUSE-SLE-15.5-2023-3311
zypper al -t patch -m "poo#119008, kernel regression boo#1202138" openSUSE-SLE-15.5-2023-3172
zypper al -t patch -m "poo#119008, kernel regression boo#1202138" openSUSE-SLE-15.5-2023-2871

but I doubt this is long-term maintainable. We should learn better ways to do that. E.g. research more about zypper or ask SUSE domain experts on that.

Acceptance criteria

  • AC1: Machines using auto-update still regularly update despite having package locks in place
  • AC2: Package locks are still regarded during automatic updates
  • AC3: We still don't automatically upgrade devel:openQA packages
  • AC4: We still have a reasonable OSD changelog not more than once a day with all relevant changes since the last explicit deployment

Suggestions

  • Research more about zypper or ask SUSE domain experts on that
  • Try to make zypper patch not complain about locks
  • Research why we came up with a separate auto-update service for OSD openQA machines at all (or if we can ditch that by now)
  • Fallback updates when openQA deployment pipeline runs zypper dup
  • Check whether it helps to make the package lock more specific (currently it uses a glob which might be problematic) It can be problematic to make kernel locks more specific because other packages like kernel-default-base might be installed instead.
  • Consider switching to openqa-auto-update https://github.com/os-autoinst/openQA/blob/master/script/openqa-auto-update as used on o3 and adapt osd-deployment so that we still receive reasonable changelogs

Had some look at the deployment pipeline at https://gitlab.suse.de/openqa/osd-deployment and it seems that there are some points worth discussing before proceeding here:

  • The pipeline has a rollback functionality that we would loose when switching to the o3 approach
  • The pipeline seems to run even when no update of the packages from devel:openQA is available so we would get regular updates anyway
  • The pipeline installs packages from devel:openQA but checks the jenkins pipeline that submits to devel:openQA:tested, so why not simply add the devel:openQA:tested repo and install all packages from there unconditionally?

True, but the rollback for o3 is also not that hard using zypper installing older packages from the cache

  • The pipeline seems to run even when no update of the packages from devel:openQA is available so we would get regular updates anyway

So you are saying the OSD deployment is the workaround while the auto-update doesn't work?

  • The pipeline installs packages from devel:openQA but checks the jenkins pipeline that submits to devel:openQA:tested, so why not simply add the devel:openQA:tested repo and install all packages from there unconditionally?

That shouldn't impact the original issue. But the reason is that devel:openQA:tested is really only intended for the purpose of submitting packages to openSUSE:Factory, not to be used on production systems which in our case are Leap

Updated by dheidler 7 months ago

Some untested draft: https://gitlab.suse.de/openqa/salt-states-openqa/-/merge_requests/1063

This would provide a way of declaring package locks via salt but still having locally applied package locks (hence doing https://progress.opensuse.org/issues/152092 afterwards).

It should automatically lock all patches that would conflict with package locks (both locks created by salt and by hand).

The patch locks are recreated on each salt run, so they always reflect the current package locks.

@dheidler please only resolve with enough relevant details. Just "yes" isn't really enough prove to show that all four ACs are covered.

Especially I suggest to apply extra care that automatic updates including automatic reboots don't cause problems over the upcoming vacation period.

I did on OSD

sudo salt \* cmd.run 'zypper ll; zypper -n patch --dry-run'

which looks fine so far although there are many notices which might lead to false assumptions.

so that should cover AC1.

sudo salt -C 'G@osarch:ppc64le' cmd.run 'ls -l /boot'

also shows no newer kernel updates pulled in so AC2 should be covered as well.

Can you check AC3+AC4?

I have seen that no packages from devel:openQA got updated when I ran the auto-upgrade script.
Which would be impossible anyway, because there is no pathinfo.

As I didn't touch any of the pipeline based system upgrade, nothing changed there as well.
So there is no reason why it shouldn't behave the same.
