Package: libdevmapper1.02.1 Version: 2:1.02.90-2.2 Severity: important Dear Maintainer,
After upgrading to the latest version of libdevmapper1.02.1 from unstable, I found myself unable to mount my /home logical volume due to a segfault in libdevmapper.so.1.02.1: # grep segfault /var/log/kern.log Jul 9 11:20:46 briareos kernel: [ 8.184718] lvm[1639]: segfault at 80 ip 00007f80cf3f14ef sp 00007ffe0aa24050 error 4 in libdevmapper.so.1.02.1[7f80cf3d9000+46000] Jul 9 11:20:46 briareos kernel: [ 30.719648] lvchange[1955]: segfault at 80 ip 00007f4c1ebf14ef sp 00007ffef827eca0 error 4 in libdevmapper.so.1.02.1[7f4c1ebd9000+46000] Jul 9 11:20:46 briareos kernel: [ 84.536668] lvchange[1990]: segfault at 80 ip 00007fad611b74ef sp 00007ffda2685610 error 4 in libdevmapper.so.1.02.1[7fad6119f000+46000] I'm filing this bug against libdevmapper1.02.1 specifically since the lvm2 package itself was not upgraded due to apt-listbugs pinning it following https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=791869 Here's what I ran on my system when in the boot maintenance shell: # dpkg -l lvm2 libdevmapper1.02.1 Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Architecture Description +++-==========================================================================-==========================================-==========================================-========================================================================================================================================================= ii libdevmapper1.02.1:amd64 2:1.02.99-1 amd64 Linux Kernel Device Mapper userspace library ii lvm2 2.02.111-2.2 amd64 Linux Logical Volume Manager # apt-cache policy lvm2 libdevmapper1.02.1 lvm2: Installed: 2.02.111-2.2 Candidate: 2.02.111-2.2 Package pin: 2.02.111-2.2 Version table: 2.02.122-1 1000 500 http://debian.proxad.net/debian/ sid/main amd64 Packages *** 2.02.111-2.2 1000 500 http://debian.proxad.net/debian/ jessie/main amd64 Packages 100 /var/lib/dpkg/status libdevmapper1.02.1: Installed: 2:1.02.99-1 Candidate: 2:1.02.99-1 Version table: *** 2:1.02.99-1 0 500 http://debian.proxad.net/debian/ sid/main amd64 Packages 100 /var/lib/dpkg/status 2:1.02.90-2.2 0 500 http://debian.proxad.net/debian/ jessie/main amd64 Packages # lvchange -a y /dev/mapper/vg_raid5-home zsh: segmentation fault lvchange -a y /dev/mapper/vg_raid5-home Downgrading the lvm2, libdevmapper1.02.1 and dmeventd to their jessie versions fixed the issue. In case someone encounters the same problem, for some strange reason in the boot maintenance shell /usr/sbin was not in my $PATH so I had to add it by hand: # export PATH=$PATH:/usr/sbin Before running: # apt install libdevmapper1.02.1/jessie lvm2/jessie dmeventd/jessie Else the installation would fail due to missing executables (namely update-initramfs).
