2006-04-11[PATCH] arch/i386/mach-voyager/voyager_cat.c: named initializersAdrian Bunk
This patch switches arch/i386/mach-voyager/voyager_cat.c to using named initializers for struct resource. Besides a fixing compile error in Greg's tree, it makes the code more readable.

2006-04-11[PATCH] md: make sure 64bit fields in version-1 metadata are 64-bit alignedNeilBrown
reshape_position is a 64bit field that was not 64bit aligned. So swap with new_level. NOTE: this is a user-visible change. However: - The bad code has not appeared in a released kernel - This code is still marked 'experimental' - This only affects version-1 superblock, which are not in wide use - These field are only used (rather than simply reported) by user-space tools in extemely rare circumstances : after a reshape crashes in the first second of the reshape process. So I believe that, at this stage, the change is safe. Especially if people heed the 'help' message on use mdadm-2.4.1.

2006-04-11[PATCH] sched: fix interactive task starvationMike Galbraith
Fix a starvation problem that occurs when a stream of highly interactive tasks delay an array switch for extended periods despite EXPIRED_STARVING(rq) being true. AFAIKT, the only choice is to enqueue awakening tasks on the expired array in this case. Without this patch, it can be nearly impossible to remotely login to a busy server, and interactive shell commands can starve for minutes. Also, convert the EXPIRED_STARVING macro into an inline function which humans can understand.

2006-04-10[PATCH] de_thread: Don't confuse users do_each_thread.Eric W. Biederman
Oleg Nesterov spotted two interesting bugs with the current de_thread code. The simplest is a long standing double decrement of __get_cpu_var(process_counts) in __unhash_process. Caused by two processes exiting when only one was created. The other is that since we no longer detach from the thread_group list it is possible for do_each_thread when run under the tasklist_lock to see the same task_struct twice. Once on the task list as a thread_group_leader, and once on the thread list of another thread. The double appearance in do_each_thread can cause a double increment of mm_core_waiters in zap_threads resulting in problems later on in coredump_wait. To remedy those two problems this patch takes the simple approach of changing the old thread group leader into a child thread. The only routine in release_task that cares is __unhash_process, and it can be trivially seen that we handle cleaning up a thread group leader properly. Since de_thread doesn't change the pid of the exiting leader process and instead shares it with the new leader process. I change thread_group_leader to recognize group leadership based on the group_leader field and not based on pids. This should also be slightly cheaper then the existing thread_group_leader macro. I performed a quick audit and I couldn't see any user of thread_group_leader that cared about the difference. Signed-off-by: Eric W.

2006-04-10[ARM] 3473/1: Use numbers 0-15 for the VFP double registersCatalin Marinas
Patch from Catalin Marinas This patch changes the double registers numbering to 0-15 from even 0-30, in preparation for future VFP extensions. It also fixes the VFP_REG_ZERO bug (value 16 actually represents the 8th double register with the original numbering). The original mcrr/mrrc on CP10 were generating FMRRS/FMSRR instead of FMRRD/FMDRR. The patch changes to CP11 for the correct instructions.

2006-04-10[PATCH] Fix buddy list race that could lead to page lru list corruptionsNick Piggin
Rohit found an obscure bug causing buddy list corruption. page_is_buddy is using a non-atomic test (PagePrivate && page_count == 0) to determine whether or not a free page's buddy is itself free and in the buddy lists. Each of the conjuncts may be true at different times due to unrelated conditions, so the non-atomic page_is_buddy test may find each conjunct to be true even if they were not both true at the same time (ie. the page was not on the buddy lists).

2006-04-10[Security] Keys: Fix oops when adding key to non-keyringDavid Howells
This fixes the problem of an oops occuring when a user attempts to add a key to a non-keyring key [CVE-2006-1522]. The problem is that __keyring_search_one() doesn't check that the keyring it's been given is actually a keyring. I've fixed this problem by: (1) declaring that caller of __keyring_search_one() must guarantee that the keyring is a keyring; and (2) making key_create_or_update() check that the keyring is a keyring, and return -ENOTDIR if it isn't. This can be tested by: keyctl add user b b `keyctl add user a a @s` Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-04-09[TG3]: Speed up SRAM access (2nd version)Michael Chan
Speed up SRAM read and write functions if possible by using MMIO instead of config. cycles. With this change, the post reset signature done at the end of D3 power change must now be moved before the D3 power change. IBM reported a problem on powerpc blades during ethtool self test that was caused by the memory test taking excessively long. Config. cycles are very slow on powerpc and the memory test can take more than 10 seconds to complete using config. cycles. David Miller informed me that an earlier version of the patch caused problems on sparc64 systems with built-in tg3 chips. This version fixes the problem by excluding all SUN built-in tg3 chips from doing MMIO SRAM access. TG3_FLAG_EEPROM_WRITE_PROT is also set unconditionally when TG3_FLG2_SUN_570X is set. This should be sane as all SUN chips are built-in and do not require Vaux switching. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
