Package: aufs-dkms
Version: 4.14+20171218-1
Severity: important
User: [email protected]
Usertags: misc-reported

Hi,
this bug makes aufs unusable in the context of Tails with Linux 4.14,
and possibly with any other Debian Live or container system that still
uses aufs. Initially I've identified it because it prevents Tails ISO
images with Linux 4.14 from booting, but I've reproduced it on regular
Debian systems: current sid (Linux 4.14.7-1) and Stretch (Linux
4.14.7-1~bpo9+1), in both cases with aufs-dkms 4.14+20171218-1.
Does aufs work for you with different settings?
If yes, let's stick to Severity: important… and I'm curious what
settings you're using. If not, then let's make this RC.
Here's how to reproduce:
# 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
⇒ so far, so good.
But then:
# ls /tmp/mount
Segmentation fault
Here's what I see in my kernel log:
