[PATCH] SPARC64: Fix two bugs wrt. kernel 4MB TSB.

2007-06-11T18:36:53Z

1) The TSB lookup was not using the correct hash mask. 2) It was not aligned on a boundary equal to it's size, which is required by the sun4v Hypervisor. wasn't having it's return value checked, and that bug will be fixed up as well in a subsequent changeset.

[PATCH] Fix AF_UNIX OOPS

2007-06-11T18:36:50Z

This combines two upstream commits to fix an OOPS with AF_UNIX and SELINUX. Basically, sk->sk_socket can become NULL because we access a peer socket without any locking, so it can be shut down and released in another thread. Commit: d410b81b4eef2e4409f9c38ef201253fbbcc7d94 [AF_UNIX]: Make socket locking much less confusing. The unix_state_*() locking macros imply that there is some rwlock kind of thing going on, but the implementation is actually a spinlock which makes the code more confusing than it needs to be. So use plain unix_state_lock and unix_state_unlock. Signed-off-by: David S. Miller Commit: 19fec3e807a487415e77113cb9dbdaa2da739836 [AF_UNIX]: Fix datagram connect race causing an OOPS. Based upon an excellent bug report and initial patch by Frederik Deweerdt. The UNIX datagram connect code blindly dereferences other->sk_socket via the call down to the security_unix_may_send() function. Without locking 'other' that pointer can go NULL via unix_release_sock() which does sock_orphan() which also marks the socket SOCK_DEAD. So we have to lock both 'sk' and 'other' yet avoid all kinds of potential deadlocks (connect to self is OK for datagram sockets and it is possible for two datagram sockets to perform a simultaneous connect to each other). So what we do is have a "double lock" function similar to how we handle this situation in other areas of the kernel. We take the lock of the socket pointer with the smallest address first in order to avoid ABBA style deadlocks. Once we have them both locked, we check to see if SOCK_DEAD is set for 'other' and if so, drop everything and retry the lookup. Signed-off-by: David S.

[PATCH] acpi: fix potential call to a freed memory section.

2007-06-11T18:36:50Z

Strip __cpuinit[data] from Node <-> PXM routines and supporting data structures. Also make pxm_to_node_map and node_to_pxm_map local to the numa acpi module. This fixes a bug triggered by the following conditions: - boot on a machine with a SLIT table defined - kernel is configured w/ CONFIG_HOTPLUG_CPU=n - cat /sys/devices/system/node/node*/distance This will cause an oops by calling into a freed memory section. In particular, on x86_64, __node_distance calls node_to_pxm(). Signed-off-by: Aaron Durbin Cc: Len Brown Signed-off-by: Andrew Morton Signed-off-by: Greg Kroah-Hartman Signed-off-by: Chris Wright

[PATCH] x86_64: allocate sparsemem memmap above 4G

2007-06-11T18:36:48Z

On systems with huge amount of physical memory, VFS cache and memory memmap may eat all available system memory under 4G, then the system may fail to allocate swiotlb bounce buffer. There was a fix for this issue in arch/x86_64/mm/numa.c, but that fix dose not cover sparsemem model. This patch add fix to sparsemem model by first try to allocate memmap above 4G.

[PATCH] PCI: quirk disable MSI on via vt3351

2007-06-11T18:36:47Z

The Via VT3351 APIC does not play well with MSI and unleashes a flood of APIC errors when MSI is used to deliver interrupts. The problem was recently exposed when the atl1 network device driver, which enables MSI by default, stimulated APIC errors on an Asus M2V mainboard, which employs the Via VT3351. See http://bugzilla.kernel.org/show_bug.cgi?id=8472 for additional details on this bug. Signed-off-by: Jay Cliburn Signed-off-by: Greg Kroah-Hartman Signed-off-by: Chris Wright

[PATCH] make freezeable workqueues singlethread

2007-06-11T18:36:45Z

It is a known fact that freezeable multithreaded workqueues doesn't like CPU_DEAD. We keep them only for the incoming CPU-hotplug rework. Sadly, we can't just kill create_freezeable_workqueue() right now, make them singlethread. Signed-off-by: Oleg Nesterov Cc: "Rafael J.

[PATCH] md: Don't write more than is required of the last page of a bitmap

2007-06-11T18:36:44Z

It is possible that real data or metadata follows the bitmap without full page alignment. So limit the last write to be only the required number of bytes, rounded up to the hard sector size of the device. Signed-off-by: Neil Brown Signed-off-by: Chris Wright Signed-off-by: Greg Kroah-Hartman
