After an upgrade to libfuse 3.17.1-rc0, autopkgtests started to fail due to a missing x permission for /usr/bin/mount. After looking at the source code for fusermount, I noticed that it does call /bin/mount and /bin/umount in certain cases. These uses were already there in previous versions of libfuse but I'm still not sure why it hasn't triggered before. To reproduce it: ``` sudo autopkgtest-buildvm-ubuntu-cloud -v -r questing autopkgtest archivemount -U --apt-pocket=proposed=src:fuse3 --shell-fail -- qemu autopkgtest-questing-amd64.img ``` After the test fails, enter the vm by ``` ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -p 10022 ubuntu@localhost ``` You can reproduce the test by running ``` cd /tmp/autopkgtest.*/build.*/src/ /tmp/autopkgtest.*/build.*/src/debian/tests/test ``` Note that ix for mount and umount were enough to make the autopkgtest failures to start passing, but there could be issues in the future regarding the use of fs specific mount binaries like /usr/sbin/mount.fuse Fixes: http://bugs.launchpad.net/bugs/2111845 Signed-off-by: Georgia Garcia <georgia.garcia@canonical.com> MR: https://gitlab.com/apparmor/apparmor/-/merge_requests/1716 Approved-by: John Johansen <john@jjmx.net> Merged-by: John Johansen <john@jjmx.net>
