security: use mmap_min_addr indepedently of security models

2009-08-13T22:06:08+00:00

This patch removes the dependency of mmap_min_addr on CONFIG_SECURITY.
It also sets a default mmap_min_addr of 4096.

mmapping of addresses below 4096 will only be possible for processes
with CAP_SYS_RAWIO.

futex: Restore one of the fast paths eliminated by 38d47c1b7075bd7ec3881141bb3629da58f88dab

2009-06-10T22:05:40+00:00

This improves futex performance until our user-space code is fixed to use
FUTEX_PRIVATE_FLAG for non-shared futexes.

nohz: Fix ondemand governor not always ramping up on 100% load.

2009-05-29T23:46:13+00:00

On systems that perform the context switch with interrupts enabled
(e.g. ARM) get_cpu_idle_time_us could get stuck returning the last
idle time when the cpu is busy. If an interrupt occurs while
switching to the idle thread, and this interrupt wakes up a thread,
need-resched will be set on the idle thread, but since we have not
finished switching to the idle thread tick_nohz_stop_sched_tick will
be called. (idle_cpu is true since the head of the runqueue is the
idle thread, but need_resched returns false since we are still
running in the context of the old thread)

Fix this by not calling tick_nohz_start_idle when returning from an
interrupt while the idle thread is in its schedule phase.

cgroup: Add generic cgroup subsystem permission checks.

2009-05-21T23:18:04+00:00

    Rather than using explicit euid == 0 checks when trying to move
tasks into a cgroup via CFS, move permission checks into each
specific cgroup subsystem. If a subsystem does not specify a
'can_attach' handler, then we fall back to doing our checks the old way.

    This way non-root processes can add arbitrary processes to
a cgroup if all the registered subsystems on that cgroup agree.

    Also change explicit euid == 0 check to CAP_SYS_ADMIN
