Dear aufs-maintainer, below a Debian bug reporting a seg fault is attached. A online version of the bug can be found here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=886329 I could reproduce the bug using a 4.15 kernel. Could you please take a look into this? Thank you very much and

Hey, could you please provide the additional information the upstream developer requests for in the README, then I will forward it to upstream: 5. Contact When you have any problems or strange behaviour in aufs, please let me know with: - /proc/mounts

Jan Luca Naumann: > the underlying filesystem is a tmpfs for me as well: > [...] > I get no segfault for the call still so there has to be another reason... Indeed! I've just reproduced this in an up-to-date sid VM where /tmp is on the ext4 root filesystem. I've purged and reinstalled aufs-dkms

Hey, the underlying filesystem is a tmpfs for me as well: # uname -a Linux 4.14.0-3-amd64 #1 SMP Debian 4.14.13-1 (2018-01-14) x86_64 # mount | grep /tmp none on /tmp type tmpfs (rw,nosuid,nodev,noatime,nodiratime) # modprobe aufs debug=1 \ && mkdir /tmp/{ro,rw,mount} \ && touch

Hi, in case it might help other Live systems still using aufs for some reason, for the record I've implemented a workaround to this bug in Tails:

Hi, interestingly, only the first access to the aufs mountpoint triggers the bug. See the first `ls' failing and the second one working: # modprobe aufs debug=1 \ && mkdir /tmp/{ro,rw,mount} \ && touch /tmp/ro/bla \ && mount -t aufs -o dirs =/tmp/rw=rw:/tmp/ro=rr+wh aufs /tmp/mount
