[Devel] [PATCHSET] 2.6.20-lxc8

[Cedric Le Goater]

All,

We've been gathering, porting and testing a whole bunch of patchsets
related to namespaces, containers and resource management in what
we call the -lxc patchset. 

The purpose of the -lxc patchset is to experiment and test a "fully" 
featured linux container solution. this is a large topic but resource 
management and container mobility are the main high level features we
are looking at.

We're not there yet but we've done a lot of progress in 2006 and early 
2007. It seems a good time to share some this work and see :
 
	* which patchsets can be proposed to andrew
	* which patchsets requires more work 
	* which can be dropped
	* what kind of cleanups are still required
	* etc.

The latest release 2.6.20-lxc8 contains the following :

* user namespace from Serge E. Hallyn <serue at us.ibm.com>
* bind_ns() syscalls from Cedric Le Goater <clg at fr.ibm.com>
* ro bind mount from Dave Hansen <hansendc at us.ibm.com>
* generic Process containers from Paul Menage <menage at google.com>
* namespace entering from Serge E. Hallyn <serue at us.ibm.com>
* resource controllers based on process containers from Pavel Emelianov <xemul at sw.ru>
* multiple /proc (required for pid namespace) from Dave Hansen <hansendc at us.ibm.com>
* pid namespace from Sukadev Bhattiprolu <sukadev at us.ibm.com>
* L2 network namespace from Eric W. Biederman <ebiederm at xmission.com>
* misc fixes and cleanups from others (sorry for not mentioning)

and it's giving some good results on common platforms like i386 and 
x86_64.

It's all here :

	http://lxc.sourceforge.net/patches/2.6.20/2.6.20-lxc8

Some very basic user space tools to work and test namespaces can 
also be found here : 

	http://lxc.sourceforge.net/patches/2.6.20/2.6.20-lxc8/broken-out/tests/

A lot of work still needs to be done in user space..this is not 
the highest priority for the moment but sooner or later we'll 
need to spend more time on it. 

Hope you find it useful. If you have any issues with sourceforge 
download, please tell me. I can move this patchset to a more 
convenient site.

Cheers,

C.
