2005-09-29[PATCH] x86_64: Fix mce_logMike Waychison
The attempt to fixup the lockless mce log buffer introduced an infinite loop when trying to find a free entry. And: Using rcu_dereference() to load mcelog.next doesn't seem to be sufficient enough to ensure that mcelog.next is loaded each time around the loop in mce_log(). Instead, use an explicit rmb() to ensure that the compiler gets it right. AK: turned the smp_wmbs into true wmbs to make sure they are not reordered by the compiler on UP.

2005-09-29[PATCH] Fix task state testing properly in do_signal_stop()Roland McGrath
Any tests using < TASK_STOPPED or the like are left over from the time when the TASK_ZOMBIE and TASK_DEAD bits were in the same word, and it served to check for "stopped or dead". I think this one in do_signal_stop is the only such case. It has been buggy ever since exit_state was separated, and isn't testing the exit_state value.

2005-09-29Revert task flag re-ordering, add commentsLinus Torvalds
Roland points out that the flags end up having non-obvious dependencies elsewhere, so revert aa55a08687059aa169d10a313c41f238c2070488 and add some comments about why things are as they are.

2005-09-29[PATCH] fix TASK_STOPPED vs TASK_NONINTERACTIVE interactionOleg Nesterov
do_signal_stop: for_each_thread(t) { if (t->state < TASK_STOPPED) ++sig->group_stop_count; } However, TASK_NONINTERACTIVE > TASK_STOPPED, so this loop will not count TASK_INTERRUPTIBLE | TASK_NONINTERACTIVE threads. See also wait_task_stopped(), which checks ->state > TASK_STOPPED. Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> [ We really probably should always use the appropriate bitmasks to test task states, not do it like this. Using something like #define TASK_RUNNABLE (TASK_RUNNING | TASK_INTERRUPTIBLE | \ TASK_UNINTERRUPTIBLE | TASK_NONINTERACTIVE) and then doing "if (task->state & TASK_RUNNABLE)" or similar. But the ordering of the task states is historical, and keeping the ordering does make sense regardless. ] Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-09-28[PATCH] Keys: Add possessor permissions to keys [try #3]David Howells
The attached patch adds extra permission grants to keys for the possessor of a key in addition to the owner, group and other permissions bits. This makes SUID binaries easier to support without going as far as labelling keys and key targets using the LSM facilities. This patch adds a second "pointer type" to key structures (struct key_ref *) that can have the bottom bit of the address set to indicate the possession of a key. This is propagated through searches from the keyring to the discovered key. It has been made a separate type so that the compiler can spot attempts to dereference a potentially incorrect pointer. The "possession" attribute can't be attached to a key structure directly as it's not an intrinsic property of a key. Pointers to keys have been replaced with struct key_ref *'s wherever possession information needs to be passed through. This does assume that the bottom bit of the pointer will always be zero on return from kmem_cache_alloc(). The key reference type has been made into a typedef so that at least it can be located in the sources, even though it's basically a pointer to an undefined type. I've also renamed the accessor functions to be more useful, and all reference variables should now end in "_ref".

2005-09-28[PATCH] device-mapper: Fix queue_if_no_path initialisationAlasdair G Kergon
When creating a multipath device, if the queue_if_no_path parameter is specified it gets ignored. While the queue_if_no_path variable is correctly set to 1, the saved_queue_if_no_path gets set to 0. When the device is subsequently made live (resumed), the saved value (0) always overwrites the live value (1) so the option *always* gets turned off. The fix adds a parameter to the queue_if_no_path() function to indicate whether the previous value should be preserved or not - if not, as when the device is being set up, the saved value is set to the new value (1).
