    • console API improvements · b5159817
      Dwight Engen authored 
      Add a higher level console API that opens a tty/console and runs the
mainloop as well. Rename existing API to console_getfd(). Use these in
the python binding.

Allow attaching a console peer after container bootup, including if the
container was launched with -d. This is made possible by allocation of a
"proxy" pty as the peer when the console is attached to.

Improve handling of SIGWINCH, the pty size will be correctly set at the
beginning of a session and future changes when using the lxc_console() API
will be propagated to it as well.

Refactor some common code between lxc_console.c and console.c. The variable
wait4q (renamed to saw_escape) was static, making the mainloop callback not
safe across threads. This wasn't a problem when the callback was in the
non-threaded lxc-console, but now that it is internal to console.c, we have
to take care of it. This is now contained in a per-tty state structure.

Don't attempt to open /dev/null as the console peer since /dev/null cannot
be added to the mainloop (epoll_ctl() fails with EPERM). This isn't needed
to get the console setup (and the log to work) since the case of not having
a peer at console init time has to be handled to allow for attaching to it
later.

Move signalfd libc wrapper/replacement to utils.h.

    • lxc-init: continue even if we fail to mount /dev/mqueue · 5d4d3ebb
      Natanael Copa authored 
      The 'lxc-init' (a lightweight init process used by lxc-execute in place
of upstart etc) tries to mount /dev/mqueue during startup. If that fails
(for instance due to missing support for mqueue in kernel) then it
aborts execution and returns -1. This is unreasonable as very few
applications actually need /dev/mqueue.

This similar to what we do with /dev/shm.

    • Move container creation fully into the api · 1897e3bc
      Serge Hallyn authored 
      1. implement bdev->create:

python and lua: send NULL for bdevtype and bdevspecs.
They'll want to be updated to pass those in in a way that makes
sense, but I can't think about that right now.

2. templates: pass --rootfs

If the container is backed by a device which must be mounted (i.e.
lvm) then pass the actual rootfs mount destination to the
templates.

Note that the lxc.rootfs can be a mounted block device.  The template
should actually be installing the rootfs under the path where the
lxc.rootfs is *mounted*.

Still, some people like to run templates by hand and assume purely
directory backed containers, so continue to support that use case
(i.e. if no --rootfs is listed).

Make sure the templates don't re-write lxc.rootfs if it is
already in the config.  (Most were already checking for that)

3. Replace lxc-create script with lxc_create.c program.

Changelog:
May 24: when creating a container, create $lxcpath/$name/partial,
and flock it.  When done, close that file and unlink it.  In
lxc_container_new() and lxcapi_start(), check for this file.  If
it is locked, create is ongoing.  If it exists but is not locked,
create() was killed - remove the container.

May 24: dont disk-lock during lxcapi_create.  The partial lock
is sufficient.

    • destroy: implement in the api · 60bf62d4
      Serge Hallyn authored 
      This requires implementing bdev->ops->destroy() for each of the backing
store types.  Then implementing lxcapi_clone(), writing lxc_destroy.c
using the api, and removing the lxc-destroy.in script.

(this also has a few other cleanups, like marking some functions
static)

Changelog:
	fold into destroy: fix zfs destroy
	destroy: use correct program name in help

    • lxc-stop: use api, remove lxc_shutdown, extend lxc-stop functionality · 3e625e2d
      Serge Hallyn authored 
      implement c->reboot(c) in the api.

Also if the container is not running, return -2.  Currently
lxc-stop will return 0, so you cannot tell the difference
between successfull stopping and noop.

Per stgraber's email:

 - Remove lxc-shutdown
 - Change lxc-stop so that:
   * Default behaviour is to call shutdown(), wait 15s for STOPPED, if
not STOPPED, print a message to the user and call stop() [ NOTE:
actually 60 seconds per followup thread]
   * We have a -r option to reboot the container (with proper check that
the container indeed rebooted within the next 15s)
   * We have a -s option to shutdown the container without the automatic
fallback to stop()
   * Add a -k option allowing a user to just kill a container
(equivalent to old lxc-stop, no shutdown() call and no delay).

and update manpages.
