* capabilities: add bounding set to /proc/self/statusSerge E. Hallyn2008-05-131-0/+1
| | | | | | | | | | | | | | | | | | | | | There is currently no way to query the bounding set of another task. As there appears to be no security reason not to, and as Michael Kerrisk points out the following valid reasons to do so exist: * consistency (I can see all of the other per-thread/process sets in /proc/.../status) * debugging -- I could imagine that it would make the job of debugging an application that uses capabilities a little simpler. this patch adds the bounding set to /proc/self/status right after the effective set.

* md: fix raid5 'repair' operationsDan Williams2008-05-131-12/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | commit bd2ab67030e9116f1e4aae1289220255412b37fd "md: close a livelock window in handle_parity_checks5" introduced a bug in handling 'repair' operations. After a repair operation completes we clear the state bits tracking this operation. However, they are cleared too early and this results in the code deciding to re-run the parity check operation. Since we have done the repair in memory the second check does not find a mismatch and thus does not do a writeback. Test results: $ echo repair > /sys/block/md0/md/sync_action $ cat /sys/block/md0/md/mismatch_cnt 51072 $ echo repair > /sys/block/md0/md/sync_action $ cat /sys/block/md0/md/mismatch_cnt 0 (also fix incorrect indentation) Cc: <stable@kernel.org> Tested-by: George Spelvin <linux@horizon.com> Acked-by: NeilBrown <neilb@suse.de> Signed-off-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* quota: don't call sync_fs() from vfs_quota_off() when there's no quota turn offJan Kara2008-05-131-0/+10
| | | | | | | | | | | | | Sometimes, vfs_quota_off() is called on a partially set up super block (for example when fill_super() fails for some reason). In such cases we cannot call ->sync_fs() because it can Oops because of not properly filled in super block. So in case we find there's not quota to turn off, we just skip everything and return which fixes the above problem.

* uml: random driver fixesJeff Dike2008-05-135-31/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The random driver would essentially hang if the host's /dev/random returned -EAGAIN. There was a test of need_resched followed by a schedule inside the loop, but that didn't help and it's the wrong way to work anyway. The right way is to ask for an interrupt when there is input available from the host and handle it then rather than polling. Now, when the host's /dev/random returns -EAGAIN, the driver asks for a wakeup when there's randomness available again and sleeps. The interrupt routine just wakes up whatever processes are sleeping on host_read_wait. There is an atomic_t, host_sleep_count, which counts the number of processes waiting for randomness. When this reaches zero, the interrupt is disabled. An added complication is that async I/O notification was only recently added to /dev/random (by me), so essentially all hosts will lack it. So, we use the sigio workaround here, which is to have a separate thread poll on the descriptor and send an interrupt when there is input on it. This mechanism is activated when a process gets -EAGAIN (activating this multiple times is harmless, if a bit wasteful) and deactivated by the last process still waiting. The module name was changed from "random" to "hw_random" in order for udev to recognize it. The sigio workaround needed some changes. sigio_broken was added for cases when we know that async notification doesn't work. This is now called from maybe_sigio_broken, which deals with pts devices.

* uml: fix bad NTP interaction with clockJeff Dike2008-05-131-2/+2
| | | | | | | | | | | | | | | | UML's supposed nanosecond clock interacts badly with NTP when NTP decides that the clock has drifted ahead and needs to be slowed down. Slowing down the clock is done by decrementing the cycle-to-nanosecond multiplier, which is 1. Decrementing that gives you 0 and time is stopped. This is fixed by switching to a microsecond clock, with a multiplier of 1000.

| | | | | | | | | | | | | | | | | | Reintroduce uml_kmalloc for the benefit of UML libc code. The previous tactic of declaring __kmalloc so it could be called directly from the libc side of the house turned out to be getting too intimate with slab, and it doesn't work with slob. So, the uml_kmalloc wrapper is back. It calls kmalloc or whatever that translates into, and libc code calls it. kfree is left alone since that still works, leaving a somewhat inconsistent API.

| | | | | | | | | | | | | | Because it's not correct with a non-preemptable BKL and just causes PREEMPT kernels to have longer latencies than non-PREEMPT ones (which is obviously not the point of it at all).

If kthread_stop is called on the thread, there is no guarantee that it will still be up. We need to have the thread stay up until kthread_stop is called on it. One option would be to not even try to tear things down until after kthread_stop is called. However, in the case where there is a problem setting up the session, there's no real reason to try continuing the loop. This patch allows the thread to clean up and prepare for exit under all three conditions, but it has the thread go to sleep until kthread_stop is called. This allows us to simplify the shutdown code somewhat since we can be reasonably sure that the thread won't exit after being signaled but before kthread_stop is called. It also removes the places where the thread itself set the tsk variable since it appeared that it could have a potential race where the thread might never be shut down.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Only MIPS32 and MIPS64 CPUs implement clz/dclz. Therefore don't export __ilog2() for non MIPS32/MIPS64 cpus and use generic __fls bitop code for these cpus.
