Sorry, I missed this mail.
Following are the major changes since my last post to Containers@.
They are listed in the Changelog section of [PATCH 0/17]. Would it
be better to list them elsewhere ?
2.6.22-rc4-mm2-pidns2:
- CLONE_NEWPID value has changed to 0x20000000 and so the pidns_exec.c
example from previous version should be updated (or attached
pidns_exec.c must be used).
- Implement signal support with child pid namespaces.
- Modify is_global_init() implementation to use a global variable
- Bugfix: leaking 'struct pids'
- Limit to and optimize for MAX_NESTED_PID_NS levels of nested pid
namespaces which is currently set to 4. Support for deeper nesting
requires trivial changes to the macro and to a global variable,
pid_cahce_names[], and a kernel rebuild. clone() fails with -EINVAL
when attempting to exceed MAX_NESTED_PID_NS levels of nesting.
