Corresponding ecryptfs fixes (by David Howells) are\nhere as well.\n\nFix refcounting.  The following rules now apply:\n        1. The task pins the user struct.\n        2. The user struct pins its user namespace.\n        3. The user namespace pins the struct user which created it.\n\nUser namespaces are cloned during copy_creds().  Unsharing a new user_ns\nis no longer possible.  (We could re-add that, but it\u0027ll cause code\nduplication and doesn\u0027t seem useful if PAM doesn\u0027t need to clone user\nnamespaces).\n\nWhen a user namespace is created, its first user (uid 0) gets empty\nkeyrings and a clean group_info.\n\nThis incorporates a previous patch by David Howells.  Here\nis his original patch description:\n\n\u003eI suggest adding the attached incremental patch.

I don\u0027t imagine\n\u003e     the new root user being used for anything other than filling in a cred\n\u003e     struct.\n\u003e\n\u003e     This also permits me to get rid of a get_uid() and a free_uid(), as the\n\u003e     reference the creds were holding on the old user_struct can just be\n\u003e     transferred to the new namespace\u0027s creator pointer.\n\u003e\n\u003e (6) Makes create_user_ns() reset the UIDs and GIDs of the creds under\n\u003e     preparation rather than doing it in copy_creds().\n\u003e\n\u003eDavid\n\n\u003eSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\n\nChangelog:\n\tOct 20: integrate dhowells comments\n\t\t1. leave thread_keyring alone\n\t\t2. use current_user_ns() in set_user()\n\nSigned-off-by: Serge Hallyn \u003cserue@us.ibm.com\u003e\n"

      "message": "cgroup_clone: use pid of newly created task for new cgroup\n\ncgroup_clone creates a new cgroup with the pid of the task.  This works\ncorrectly for unshare, but for clone cgroup_clone is called from\ncopy_namespaces inside copy_process, which happens before the new pid is\ncreated.  As a result, the new cgroup was created with current\u0027s pid.\nThis patch:\n\n\t1. Moves the call inside copy_process to after the new pid\n\t   is created\n\t2. Passes the struct pid into ns_cgroup_clone (as it is not\n\t   yet attached to the task)\n\t3. Passes a name from ns_cgroup_clone() into cgroup_clone()\n\t   so as to keep cgroup_clone() itself simpler\n\t4. Uses pid_vnr() to get the process id value, so that the\n\t   pid used to name the new cgroup is always the pid as it\n\t   would be known to the task which did the cloning or\n\t   unsharing.  I think that is the most intuitive thing to\n\t   do.  This way, task t1 does clone(CLONE_NEWPID) to get\n\t   t2, which does clone(CLONE_NEWPID) to get t3, then the\n\t   cgroup for t3 will be named for the pid by which t2 knows\n\t   t3.\n\n(Thanks to Dan Smith for finding the main bug)\n\nChangelog:\n\tJune 11: Incorporate Paul Menage\u0027s feedback:  don\u0027t pass\n\t         NULL to ns_cgroup_clone from unshare, and reduce\n\t\t patch size by using \u0027nodename\u0027 in cgroup_clone.\n\tJune 10: Original version\n\n[akpm@linux-foundation.org: build fix]\n[akpm@linux-foundation.org: coding-style fixes]\nSigned-off-by: Serge Hallyn \u003cserge@us.ibm.com\u003e\nAcked-by: Paul Menage \u003cmenage@google.com\u003e\nTested-by: Dan Smith \u003cdanms@us.ibm.com\u003e\nCc: Balbir Singh \u003cbalbir@in.ibm.com\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "[PATCH] namespaces: fix exit race by splitting exit\n\nFix exit race by splitting the nsproxy putting into two pieces.  First\npiece reduces the nsproxy refcount.  If we dropped the last reference, then\nit puts the mnt_ns, and returns the nsproxy as a hint to the caller.  Else\nit returns NULL.  The second piece of exiting task namespaces sets\ntsk-\u003ensproxy to NULL, and drops the references to other namespaces and\nfrees the nsproxy only if an nsproxy was passed in.\n\nA little awkward and should probably be reworked, but hopefully it fixes\nthe NFS oops.\n\nSigned-off-by: Serge E.

      "message": "[PATCH] namespaces: incorporate fs namespace into nsproxy\n\nThis moves the mount namespace into the nsproxy.  The mount namespace count\nnow refers to the number of nsproxies point to it, rather than the number of\ntasks.  As a result, the unshare_namespace() function in kernel/fork.c no\nlonger checks whether it is being shared.\n\nSigned-off-by: Serge Hallyn \u003cserue@us.ibm.com\u003e\nCc: Kirill Korotaev \u003cdev@openvz.org\u003e\nCc: \"Eric W.
