I think this is an issue where afs_icl_AppendRecord doesn't grab a ref for anything it's using, so if it races with client shutdown, it can try to use freed memory. This should be fixed by gerrit 6431. However, I think there is a larger issue where I think pioctls should prevent AFS umount while they are running (otherwise we'd have to re-check afs_shuttingdown on every glock drop or something for sane behavior). Probably need some new osi_ os-specific glue to make that happen everywhere; I'm not going to bother for now, but it's in #130424. Also: > kernel: [905941.693321] IP: [<ffffffffa07b6cc3>] > afs_icl_AppendRecord+0xa3/0x610 [openafs] This whole code path is in the "fstrace" tracing stuff. If you turn off tracing, this should go away. -- Andrew Deason [email protected] _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
