[PATCH] Fix up page_mkclean_one(): virtual caches, s390

2007-01-10T19:05:23+00:00

- add flush_cache_page() for all those virtual indexed cache architectures. - handle s390. Signed-off-by: Peter Zijlstra Signed-off-by: Linus Torvalds [chrisw: fold in d6e88e671ac1] Signed-off-by: Chris Wright

[PATCH] Fix incorrect user space access locking in mincore() (CVE-2006-4814)

2007-01-10T19:05:23+00:00

Doug Chapman noticed that mincore() will doa "copy_to_user()" of the result while holding the mmap semaphore for reading, which is a big no-no. While a recursive read-lock on a semaphore in the case of a page fault happens to work, we don't actually allow them due to deadlock schenarios with writers due to fairness issues. Doug and Marcel sent in a patch to fix it, but I decided to just rewrite the mess instead - not just fixing the locking problem, but making the code smaller and (imho) much easier to understand.

[PATCH] fix OOM killing of swapoff

2007-01-10T19:05:23+00:00

These days, if you swapoff when there isn't enough memory, OOM killer gives "BUG: scheduling while atomic" and the machine hangs: badness() needs to do its PF_SWAPOFF return after the task_unlock (tasklist_lock is also held here, so p isn't going to be freed: PF_SWAPOFF might get turned off at any moment, but that doesn't really matter).

[PATCH] connector: some fixes for ia64 unaligned access errors

2007-01-10T19:05:23+00:00

On ia64, the various functions that make up cn_proc.c cause kernel unaligned access errors. If you are using these, for example, to get notification about all tasks forking and exiting, you get multiple unaligned access errors per process. Use put_unaligned() in the appropriate palces to fix this. Signed-off-by: Erik Jacobson Cc: Evgeniy Polyakov Cc: Tony Luck Cc: Cc: "David S.

[PATCH] NetLabel: correctly fill in unused CIPSOv4 level and category mappings

2007-01-10T19:05:23+00:00

Back when the original NetLabel patches were being changed to use Netlink attributes correctly some code was accidentially dropped which set all of the undefined CIPSOv4 level and category mappings to a sentinel value. The result is the mappings data in the kernel contains bogus mappings which always map to zero. Having level and category mappings that map to zero could result in the kernel assigning incorrect security attributes to packets. This patch restores the old/correct behavior by initializing the mapping data to the correct sentinel value. Signed-off-by: Paul Moore Signed-off-by: Chris Wright

[PATCH] asix: Fix typo for AX88772 PHY Selection

2007-01-10T19:05:23+00:00

The attached patch fixes a PHY selection problem that prevents AX88772 based devices (Linksys USB200Mv2, etc) devices from working. The interface comes up and everything seems fine except the device doesn't send/receive any packets. The one-liner attached fixes this issue and makes the devices usable again.

[PATCH] IPV4/IPV6: Fix inet{,6} device initialization order.

2007-01-10T19:05:23+00:00

It is important that we only assign dev->ip{,6}_ptr only after all portions of the inet{,6} are setup. Otherwise we can receive packets before the multicast spinlocks et al. are initialized. Signed-off-by: David L Stevens Signed-off-by: David S. Miller Signed-off-by: Chris Wright

[PATCH] SOUND: Sparc CS4231: Use 64 for period_bytes_min

2007-01-10T19:05:22+00:00

This matches what the ISA cs4231 driver uses. Tested by Georg Chini. Signed-off-by: David S. Miller Signed-off-by: Chris Wright

[PATCH] SOUND: Sparc CS4231: Fix IRQ return value and initialization.

2007-01-10T19:05:22+00:00

SBUS: Change IRQ-handler return value from 0 to IRQ_HANDLED and fix some initialisation problems. Change period_bytes_min from 4096 to 256 to allow driver to work with low latency (VOIP) applications. Hope this does not break EBUS. Signed-off-by: Georg Chini Signed-off-by: David S.
