namespaces: cleanup the code managed with PID_NS option

2008-02-08T17:22:23+00:00

Just like with the user namespaces, move the namespace management code into
the separate .c file and mark the (already existing) PID_NS option as "depend
on NAMESPACES"

namespaces: cleanup the code managed with the USER_NS option

2008-02-08T17:22:23+00:00

Make the user_namespace.o compilation depend on this option and move the
init_user_ns into user.c file to make the kernel compile and work without the
namespaces support.  This make the user namespace code be organized similar to
other namespaces'.

Also mask the USER_NS option as "depend on NAMESPACES".

namespaces: move the IPC namespace under IPC_NS option

2008-02-08T17:22:23+00:00

Currently the IPC namespace management code is spread over the ipc/*.c files.
I moved this code into ipc/namespace.c file which is compiled out when needed.

The linux/ipc_namespace.h file is used to store the prototypes of the
functions in namespace.c and the stubs for NAMESPACES=n case.  This is done
so, because the stub for copy_ipc_namespace requires the knowledge of the
CLONE_NEWIPC flag, which is in sched.h.  But the linux/ipc.h file itself in
included into many many .c files via the sys.h->sem.h sequence so adding the
sched.h into it will make all these .c depend on sched.h which is not that
good.  On the other hand the knowledge about the namespaces stuff is required
in 4 .c files only.

Besides, this patch compiles out some auxiliary functions from ipc/sem.c,
msg.c and shm.c files.  It turned out that moving these functions into
namespaces.c is not that easy because they use many other calls and macros
from the original file.  Moving them would make this patch complicated.  On
the other hand all these functions can be consolidated, so I will send a
separate patch doing this a bit later.

namespaces: move the UTS namespace under UTS_NS option

2008-02-08T17:22:23+00:00

Currently all the namespace management code is in the kernel/utsname.c file,
so just compile it out and make stubs in the appropriate header.

The init namespace itself is in init/version.c and is in the kernel all the
time.

namespaces: add the NAMESPACES config option

2008-02-08T17:22:23+00:00

The option is selectable if EMBEDDED is chosen only.  When the EMBEDDED is off
namespaces will be on.

Memory controller: resource counters

2008-02-07T16:42:18+00:00

With fixes from David Rientjes 

Introduce generic structures and routines for resource accounting.

Each resource accounting cgroup is supposed to aggregate it,
cgroup_subsystem_state and its resource-specific members within.

brk randomization: introduce CONFIG_COMPAT_BRK

2008-02-06T21:39:44+00:00

based on similar patch from: Pavel Machek 

Introduce CONFIG_COMPAT_BRK. If disabled then the kernel is free
(but not obliged to) randomize the brk area.

Heap randomization breaks ancient binaries, so we keep COMPAT_BRK
enabled by default.
