Hello Sascha, or anyone else affected, Accepted davfs2 into focal-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/davfs2/1.5.5-1ubuntu0.1 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed- focal to verification-done-focal. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed-focal. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Changed in: davfs2 (Ubuntu Focal) Status: Confirmed => Fix Committed ** Tags added: verification-needed verification-needed-focal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1883025 Title: [focal SRU] davfs2 unable to unmount: segfault error 4 in libc.so To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/davfs2/+bug/1883025/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Uploaded the debdiff in comment 1, with a couple of minor changes: 1) I ran update-maintainer to comply with https://wiki.ubuntu.com/DebianMaintainerField 2) I tweaked the version string to 1.5.5-1ubuntu0.1 to fit the scheme recommended at https://wiki.ubuntu.com/SecurityTeam/UpdatePreparation#Update_the_packaging (via https://wiki.ubuntu.com/StableReleaseUpdates#Procedure).

** Description changed: [IMPACT] umount.davfs consistently segfault in focal. This leads to a number of medium severity issues. - inability to unmount (this might have security implications) - inability to remount - autofs fails to unmount - reports of higher load in multi-user environments - computer "hangs" on shutdown waiting for successful umount completion [TEST CASE] No need for a specific test case, simply mount a resource via davfs2.mount. Calling umount.davfs2 on that mount in focal will result in a segfault every time. Exit code 255 and failure is recorded in syslog. The mount stays mounted. To verify the fix from #2 which is the backport of the fix from upstream, simply recompile davfs2 and try the procedure once more to see if the problem has been solved. [REGRESSION POTENTIAL] I will leave this mostly to others to evaluate. Currently, umount.davfs2 is completely dysfunctional so it's hard to imagine a regression for a binary that isn't doing anything except segfaulting. + [racb] Code that parses its own pidfile is being fixed. It was + segfaulting before, so as mentioned it is unlikely to break further as a + cause of this patch, except the normal latent bug being exposed on + rebuild risk. If there is a problem with the pidfile parsing being + introduced, then code further down this path could break. + [OTHER INFO] groovy and later versions have already been fixed via a new upstream release. Upstream discussion of the a and m mixup can be found at the links below. Duplicate bug 1859293 also has some very good background. [ORIGINAL REPORT] I am getting segfaults everytime I want to unmount my webdav online- space (segfault error 4). Hardware failure is impossible as I see - because error already reported on project page (and fixed).
