description |
lxcControllerRun() is calling virFileOpenTtyAt() with a slave opened on /the/container/chroot/dev/pts. While it is not documented in the manpages, glibc's grantpt does a first check (ensuring that the passed in fd is a pty slave) with '/dev/pts' as the hardcoded path, appending the pty#.
lxcControllerRun always calls this on the first slave opened after creating the new /dev/pts, so grantpt is always checking /dev/pts/0. Therefore, if your host does not have /dev/pts/0 (easy to reproduce using screen), then grantpt will fail, and the container creation will subsequently also fail. |

=================================================================
SRU Justification:
1. Impact: libvirt will be unable to create lxc containers, saying that it cannot allocate /dev/pts/0
2. Development fix: A patch was sent upstream which makes libvirt-lxc not use glibc's grantpt, which is the cause of the bug.
3. Stable fix: same as the development fix.
4. Test case:
0. [ Set up libvirt and create a libvirt-lxc container ]
1. make sure noone is logged into the server
2. log in, make sure your tty is /dev/pts/0 (check with 'tty')
3. Pin /dev/pts/0 by doing "sleep 2h & disown; exit"
4. Try to start a container on that system. Without this fix it will fail with an error about /dev/pts/0.
5. Regression potential: if the patch was bad, it could cause failures when starting a container, or other places when libvirt allocates a tty.
