This adds a basic python binding done in C and a python overlay to
extend some features and provide a user-friendlier API.
This python API only supports python 3.x and was tested with >= 3.2.
It's disabled by default in configure and can be turned on by using
--enable-python.
A basic example of the API can be found in src/python-lxc/test.py.
More documentation and examples will be added soon.
This turns liblxc into a public library implementing a container structure.
The container structure is meant to cover most LXC commands and can easily be
used to write bindings in other programming languages.
More information on the new functions can be found in src/lxc/lxccontainer.h
Test programs using the API can also be found in src/tests/

Hi,
This patch is so far just a proof of concept. The libseccomp api will be
changing soon so it probably wouldn't be worth pulling this until it is
updated for the new API.
This patch introduces support for seccomp to lxc. Seccomp lets a program
restrict its own (and its children's) future access to system calls. It
uses a simple whitelist system call policy file. It would probably be
better to switch to something more symbolic (i.e specifying 'open' rather
than the syscall #, especially given container arch flexibility).
I just wanted to get this out there as a first step. You can also get
source for an ubuntu package based on this patch at

These variables are not expanded correctly in doc/lxc-create.sgml.in
and a workaround is in place to ensure ${localstatedir}, and ${datadir}
are set in the various shell scripts that use it. There is no workaround
to ensure ${datadir} is set in src/lxc/lxc-create.in, nor is
${localstatedir} set in templates/lxc-altlinux.in so I think that these
are currently broken.
Using AS_AC_EXPAND instead of AC_SUBST fixes these problems and removes
the need for the workarounds. In addition the lxc-start-ephemeral.in
script can be autoconf'ed instead of sed'ed by the makefile.

This could be done as generic 'lsm_init()' and 'lsm_load()' functions,
however that would make it impossible to compile one package supporting
more than one lsm. If we explicitly add the selinux, smack, and aa
hooks in the source, then one package can be built to support multiple
kernels.
The smack support should be pretty trivial, and probably very close
to the apparmor support.
The selinux support may require more, including labeling the passed-in
fds (consoles etc) and filesystems.
If someone on the list has the inclination and experience to add selinux
support, please let me know. Otherwise, I'll do Smack and SELinux.

It optionally waits (an optional timeout # of seconds) for the container to
be STOPPED. If given -r, it reboots the container (and exits immediately).
I decided to add the timeout after all because it's harder to finagle into
an upstart post-stop script than a full bash script.

This patch fixes some makefile/specfile issues when running
rpmbuild with the distributed lxc specfile:
- fixes usage of installation directories for config files,
rootfs, templates and lxc-init so that they're calculated
at make time instead of configure time. Thanks to this,
all installed items go under $RPM_BUILD_ROOT when running
rpmbuild
- introduce --disable-rpath option to configure to avoid
check-rpaths errors when building non-root.
- introduce a lxc-libs package in the default spec file
to allow concurrent installation of 32 bit and 64 bit
libraries.
v2: - fix circular reference in lxc.pc
- ship lxc.pc with lxc-devel

The good news is, starting with next openSUSE release (and next SLES 11
Service Pack), patching /etc/init.d/boot won't be needed anymore for
LXC, we integrated detection of LXC (through container variable set to
lxc) in /etc/init.d/boot and /dev is no longer mounted automatically by
initscript.

Consolidate lucid, maverick, natty, and oneiric templates into one 'ubuntu'
template.
Add support for specifying architecture.
Add support for '--trim|-x' option, which removes services like the lucid
template used to. This creates smaller, faster-booting containers, but they
will not be safe with certain upgrades, like mountall or udev. When -x is
not specified for lucid or maverick container, then install lxcguest from
the ubuntu-virt ppa, since it does not exist in the official archives, and
the container is not safe to boot without lxcguest.
Add support for '--bindhome <user>' option, which will cause /home/<user>
to be bind-mounted into the container, and create the user with his
original password, shell, and group memberships in the container.
changelog:
june 23:
lxc-ubuntu template: set lxc.arch in config
install lxcguest when NOT trimming the container

Create an lxc-clone script to clone containers. It should probably
be factored into helpers and then enhanced, in particular to convert
between LVM and non-LVM containers, create non-snapshot LVM clones,
support loopback devices, and, when stable enough, to use
overlayfs, btrfs, etc.
But this is a start.

Rename 'ubuntu' template to 'lucid'
Add new maverick and natty templates, which do much less tweaking
of the environment. These should only be used on a kernel which
supports sysfs tagging for /sys/class/net, as udev will be running
in the container.
The natty template needed to slightly change the installed packages
for dhclient to be correclty installed.

The future kernel 2.6.33 will incorporate the macvlan bridge
mode where all the macvlan will be able to communicate if they are
using the same physical interface. This is an interesting feature
to have containers to communicate together. If we are outside of the
container, we have to setup a macvlan on the same physical interface than
the containers and use it to communicate with them.
