@Bevan: Thank you. I should have guessed that. I'm using openafs-modules-dkms. And now it works for me.

Bevan commented on 2023-10-06 11:22 (UTC)

@drslmr: You need to patch the openafs-modules or openafs-modules-dkms package, depending on which of the two you are using. This package (openafs) does not need to be patched as it does not contain any kernel-specific code.

I am planning to roll out exactly that change later today.

drslmr commented on 2023-10-06 11:19 (UTC)

Just for curiosity I tried to patch openafs 1.8.10-1 with e18f420.diff from gerrit.

I installed the patched openafs package and upgraded to kernel 6.5.5. I also reinstalled openafs-modules-dkms.

But the BUG still occurs.

Could anyone tell me what I missed?

Bevan commented on 2023-09-22 18:15 (UTC)

Just a heads up: The kernel BUG with Linux 6.5 is a false alarm in the sense that no actual buffer overflow occurs. However, it leaves the system in quite a bad state where syncs just hang and the system won't properly shut down anymore.

A patch is developed and discussed at https://gerrit.openafs.org/#/c/15573/. Currently, there are different opinions on which of two solution is preferable. I may add a minimal patch to the openafs-modules packages as soon as I'm confident that the patch does no harm.

For now, using linux-lts stays the safest option.

Bevan commented on 2023-09-14 18:59 (UTC)

The issue is easily reproducible. I could not find any related patch and for me it's not trivial to fix either. So I posted to the openafs-devel mailing list: https://lists.openafs.org/pipermail/openafs-devel/2023-September/020888.html

drslmr commented on 2023-09-14 10:36 (UTC)

@alexiri I was just about to post the same thing. I downgraded linux 6.4.12.arch1-1.

Bevan commented on 2023-09-14 10:35 (UTC)

Oh, that does not look good. I have not tested with Linux 6.5 yet but will do so later today. I don't see any more pending upstream patches, so I guess some debugging will be required.

afsd is crashing on 6.5.3-zen1-1-zen, has anybody else seen this?

The kmod loads successfully, but afsd crashes when openafs-client starts (12 seconds later, in this case).

Moving to linux-lts works as a workaround.

Bevan commented on 2022-10-17 14:12 (UTC)

@valerionew: This package only contains the userspace part of OpenAFS. The kernel modules are in openafs-modules (which depends on linux-headers) or openafs-modules-modules-dkms.

valerionew commented on 2022-10-17 13:54 (UTC)

Should this also need linux-headers?
