[PATCH] nsproxy cloning error path fix

2006-10-02T14:57:22Z

This patch fixes copy_namespaces()'s error path. when new nsproxy (new_ns) is created pointers to namespaces (ipc, uts) are copied from the old nsproxy. Later in copy_utsname, copy_ipcs, etc. according namespaces are get-ed. On error path needed namespaces are put-ed, so there's no need to put new nsproxy itelf as it woud cause putting namespaces for the second time. Found when incorporating namespaces into OpenVZ kernel. Signed-off-by: Pavel Emelianov Acked-by: Serge Hallyn Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] IPC namespace core

2006-10-02T14:57:22Z

This patch set allows to unshare IPCs and have a private set of IPC objects (sem, shm, msg) inside namespace. Basically, it is another building block of containers functionality. This patch implements core IPC namespace changes: - ipc_namespace structure - new config option CONFIG_IPC_NS - adds CLONE_NEWIPC flag - unshare support [clg@fr.ibm.com: small fix for unshare of ipc namespace] [akpm@osdl.org: build fix] Signed-off-by: Pavel Emelianov Signed-off-by: Kirill Korotaev Signed-off-by: Cedric Le Goater Cc: "Eric W.

[PATCH] namespaces: utsname: implement CLONE_NEWUTS flag

2006-10-02T14:57:22Z

Implement a CLONE_NEWUTS flag, and use it at clone and sys_unshare. [clg@fr.ibm.com: IPC unshare fix] [bunk@stusta.de: cleanup] Signed-off-by: Serge Hallyn Cc: Kirill Korotaev Cc: "Eric W.

[PATCH] namespaces: utsname: implement utsname namespaces

2006-10-02T14:57:21Z

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.

[PATCH] namespaces: incorporate fs namespace into nsproxy

2006-10-02T14:57:20Z

This moves the mount namespace into the nsproxy. The mount namespace count now refers to the number of nsproxies point to it, rather than the number of tasks. As a result, the unshare_namespace() function in kernel/fork.c no longer checks whether it is being shared. Signed-off-by: Serge Hallyn Cc: Kirill Korotaev Cc: "Eric W.

[PATCH] nsproxy: move init_nsproxy into kernel/nsproxy.c

2006-10-02T14:57:20Z

Move the init_nsproxy definition out of arch/ into kernel/nsproxy.c. This avoids all arches having to be updated. Compiles and boots on s390. Signed-off-by: Serge E.

[PATCH] namespaces: add nsproxy

2006-10-02T14:57:20Z

This patch adds a nsproxy structure to the task struct. Later patches will move the fs namespace pointer into this structure, and introduce a new utsname namespace into the nsproxy. The vserver and openvz functionality, then, would be implemented in large part by virtualizing/isolating more and more resources into namespaces, each contained in the nsproxy.
