This bug appears to have been reported against 'rawhide' during the Fedora 23 development cycle.
Changing version to '23'.

(As we did not run this process for some time, it could affect also pre-Fedora 23 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 23 End Of Life. Thank you.)

Kernel support for kexec and kprobes has landed upstream in the 4.8 kernel

Upstream (v5 patch set) support for kexec

Initial kexec-tools aarch64 support for Fedora.

Any comments or can I push this?

Hi, Peter,

kexec has been upstreamed, but kdump is not yet. I usually rebase new kexec-tools after upstream kexec-tools bumps a new version. So it means we will have it after a rebase.

Simon, the upstream kexec-tools maintainer will release a new version roughly match mainline kernel release schedule.

Do you want the backport now? Or can we wait for next rebase.

Please let us know, if you think it is urgent, either you or Pratyush can post the backport patches to Fedora kexec list, we can merge them after passing patch review.

Thanks
Dave

I would dearly love to land this in Fedora 25 for GA which freezes on Nov 1st [1] and get it enabled in anaconda (so we'd need to co-ordinate a build there).

I'm not sure if anaconda uses the kdump side of the functionality although I've not looked closed hence only adding the kexec bits in that patch (I did vaguely look at the kdump side of things).

The bits actually used by the installer are the more interesting bits for the GA release because we don't respin post GA where as other functionality can go out as a standard update process.

Peter,

So, could you please post the backports to Fedora kexec list after review I can hopefully merge and build it before f25 freeze..

Thanks
Dave

It's attached to this BZ. If it really must be posted by me to the list please provide a link to the list

Yes, please, we need review the patches and do some test.

FYI, the kexec list is below:

Hi Peter,

The patch "v5-2-3-arm64-Add-arm64-kexec-support.patch" is quite different from the upstream commit 522df5. Can I use the patch from upstream instead?

Thx,
Pingfan

It was v5 of the upstream patch, feel free to use whichever you prefer as you're the maintainers. I just put together a patch to start things moving forward.

Since Pingfan will send the patch, reassigned to him, Pratyush can help review the patch.

Peter, suppose we can merge it Wednesday. I assume we just create a build, make a F25 update, but first an update will be in updates-testing then in stable, how can we ensuer it being in F25 compose?

It just needs to be stable (f25) by Monday for freeze. Once it's on it's way to testing I'll submit a PR for the anaconda side of things. Current window to get things stable is 3 days so it should be fine.

Here is the update, Peter, please help on submitting a PR so that we can get it in F25.

Hmm, according to comment #18 you would like to open a PR for the anaconda side of thing, I'm not sure what is it though.

And that has nothing to do with this bug? If so, just ignore the comment..

Any reason it wasn't built for F-26 too? For anaconda they'll want to land it into rawhide too and ATM it'll break the compose/install on rawide so people will scream.

I planned to do it later this week or early next week since it is not urgent.
