dup_mnt_ns() and clone_uts_ns() return NULL on failure. This is wrong, create_new_namespaces() uses ERR_PTR() to catch an error. This means that the subsequent create_new_namespaces() will hit BUG_ON() in copy_mnt_ns() or copy_utsname(). Modify create_new_namespaces() to also use the errors returned by the copy_*_ns routines and not to systematically return ENOMEM. [oleg@tv-sign.ru: better changelog] Signed-off-by:

sys_clone() and sys_unshare() both makes copies of nsproxy and its associated namespaces. But they have different code paths. This patch merges all the nsproxy and its associated namespace copy/clone handling (as much as possible). Posted on container list earlier for feedback. - Create a new nsproxy and its associated namespaces and pass it back to caller to attach it to right process. - Changed all copy_*_ns() routines to return a new copy of namespace instead of attaching it to task->nsproxy. - Moved the CAP_SYS_ADMIN checks out of copy_*_ns() routines. - Removed unnessary !ns checks from copy_*_ns() and added BUG_ON() just incase. - Get rid of all individual unshare_*_ns() routines and make use of copy_*_ns() instead.

This patch defines the uts namespace and some manipulators. Adds the uts namespace to task_struct, and initializes a system-wide init namespace. It leaves a #define for system_utsname so sysctl will compile. This define will be removed in a separate patch. [akpm@osdl.org: build fix, cleanup] Signed-off-by:
