1. fix inconsistent use of '--auth-key' (not --auth_key) which broke their usage 2. add --debug option to lxc-ubuntu (which does set -x to show what broke) (idea from Idea from lifeless and benji) 3. fix incorrect assumption about group with -b option. User's default group may not be the same as username. Signed-off-by: -

We were doing the check for whether we need to watch utmp from a thread cloned from that which will actually do the utmp watching. As a result, the utmp file was always being watched, even if it didn't need to be. Move the check to the parent thread.

when using ns cgroup, use /cgroup/<init-cgroup> rather than /cgroup/<init-cgroup>/lxc At least lxc-start, lxc-stop, lxc-cgroup, lxc-console and lxc-ls work with this patch. I've tested this in a 2.6.35 kernel with ns cgroup, and in a 3.2 kernel without ns cgroup. Note also that because of the check for container reboot support, if we're using the ns cgroup we now end up with a /cgroup/<container>/2 cgroup created, empty, by the clone(CLONE_NEWPID). I'm really not sure how much time we want to spend cleaning such things up since ns cgroup is deprecated in kernel. Signed-off-by:

1. --path is meant to be passed by lxc-create, but should not be passed in by users. Don't advertise it in --help. 2. --clean syntax ends up not making much sense. Get rid of it, and add '--flush-cache' option instead. Signed-off-by:

In order for reboot(LINUX_REBOOT_CMD_CADON) to detect whether container reboot is supported, it must be done in a non-init pid namespace. Fix that. Signed-off-by:

The 'lxc-init' (a lightweight init process used by lxc-execute in place of upstart etc) tries to mount /dev/shm during startup. If that fails (for instance /dev/shm does not exist) then it aborts execution and returns -1. This is unreasonable as very few applications actually need /dev/shm. Signed-off-by:

Don't call it an error if a container exits without calling sys_reboot. Particularly since that will almost always be the case with lxc-execute. This fixes a regression introduced in commit "49296e2ebfe7c5f9d6ebafbb54f5c5e56a0cc085: support proper container reboot" Signed-off-by:

Use the correct path for the container's cgroup task file. Also exit out early and cleanly if the container is not running, and bind-mount /proc/$pid/net with '-n' to keep the entry out of mtab, else the mtab entry will never go away. Signed-off-by:

This patch looks for Daniel's kernel patch allowing the lxc monitor to tell container reboot from shutdown based on the exit signal. If that patch is not there, utmp monitoring is used. Otherwise, it only looks for the signal. Note that the 'conf->need_utmp_watch' is technically not necessary, as there is no harm in watching the utmp file. Signed-off-by:

1. Some templates copy the cached pristine rootfs using 'cp a b' where b is $lxc_path/$name/rootfs. That doesn't do the right thing if rootfs already exists, as it will when it is an lvm or other mount. So switch to 'rsync a/ b/'. (cp can be made to work too of course). 2. Update lxc-create to support backing stores. For now only lvm is implemented. Signed-off-by:

With this patch, I can start a container 'o1' inside another container 'o1'. (Of course, the containers must be on a different subnet) Detail: 1. Create cgroups for containers under /lxc. 2. Support nested lxc: respect init's cgroup: Create cgroups under init's cgroup. So if we start a container c2 inside a container 'c1', we'll use /sys/fs/cgroup/freezer/lxc/c1/lxc/c2 instead of /sys/fs/cgroup/freezer/c2. This allows a container c1 to be created inside container c1 It also allow a container's limits to be enforced on all a container's children (which a MAC policy could already enforce, in which case current lxc code would be unable to nest altogether). 3. Finally, if a container's cgroup already exists, rename it rather than failing to start the container. Try to WARN the user so they might go clean the old cgroup up. Whereas without this patch, container o1's cgroup would be /sys/fs/cgroup/<subsys>/o1, it now becomes /sys/fs/cgroup/<subsys>/<initcgroup>/lxc/o1 so if init is in cgroup '/' then o1's freezer cgroup would be: /sys/fs/cgroup/freezer/lxc/o1 Changelog: . make lxc-ps work with separate mtab. If cgroups were mounted with -n, and mtab is not linked to /proc/self/mounts, then 'mount -t cgroup' won't show these mounts. So make lxc-ps not use it, but rather use /proc/self/mounts directly. . lxc-ls in the past assumed that a container's cgroup was just '/<name>'. Now it is '/<host-init-cgroup>/lxc/<name>'. Handle that. . first version of this patch was setting clone_children on <path-to-cpusets-cgroup>/<init-cgroup>/lxc, not the parent of that dir. That failed to initialize that cgroup, so tasks could not enter it. Signed-off-by:

Particularly for LTS releases, which many people will want to use in their containers, it is not wise to not use -security and -updates. Furthermore the fix allowing ssh to allow the container to shut down is in lucid-updates only. With this patch, after debootstrapping a container, we add -updates and -security to sources.list and do an apt-get upgrade under chroot. Unfortunately we need to do this because debootstrap doesn't know how to. Signed-off-by:
