This patch fixes the address length checks in the selinux_socket_connect hook to be no more restrictive than the underlying ipv4 and ipv6 code; otherwise, this hook can reject valid connect calls. This patch is in response to a bug report where an application was calling connect on an INET6 socket with an address that didn't include the optional scope id and failing due to these checks.

Somewhere recently, the TSC got re-enabled for timekeeping on NUMAQ machines. However, the hardware makes these get unsynchronized quite badly. So badly, in fact, that the code to fix up the skew can just hang on boot. This patch re-disables them. It's nicely confined to the numaq.c file. It would be great if this could make it into 2.6.13, I think it counts as a bugfix. Tested on a 16-proc 4-node NUMAQ. Signed-off-by:

(We found this (after a customer complained) and it is in the kernel.org kernel. Seems that for CLOCK_MONOTONIC absolute timers and clock_nanosleep calls both the request time and wall_to_monotonic are subtracted prior to the normalize resulting in an overflow in the existing normalize test. This causes the result to be shifted ~4 seconds ahead instead of ~2 seconds back in time.) The normalize code in posix-timers.c fails when the tv_nsec member is ~1.2 seconds negative. This can happen on absolute timers (and clock_nanosleeps) requested on CLOCK_MONOTONIC (both the request time and wall_to_monotonic are subtracted resulting in the possibility of a number close to -2 seconds.) This fix uses the set_normalized_timespec() (which does not have an overflow problem) to fix the problem and as a side effect makes the code cleaner. Signed-off-by:

It's wrong to pop a fixed number of words from stack before calling sigreturn, as the number depends on what code is generated by the compiler for the start of stub_segv_handler(). What we need is esp containing the address of sigcontext. So we explicitly load that pointer into esp. Signed-off-by:

We added an include of asm/vm86.h in include/asm-i386/ptrace.h. Since UML includes the underlying arch's ptrace.h, it needs an asm/vm86.h in order to build. Signed-off-by:

Just a Kbuild subtlety, not listing a target file inside targets causes it to be rebuilt each time, and as a consequence everything depending on it is rebuilt. Signed-off-by:

With Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Revert the following patch, because of miscompilation problems in different environments leading to UML not working *at all* in TT mode; it was merged lately in 2.6 development cycle, a little after being written, and has caused problems to lots of people; I know it's a bit too long, but it shouldn't have been merged in first place, so I still apply for inclusion in the -stable tree. Anyone using this feature currently is either using some older kernel (some reports even used 2.6.12-rc4-mm2) or using this patch, as included in my -bs patchset. For now there's not yet a fix for this patch, so for now the best thing is to drop it (which was widely reported to give a working kernel, and as such was even merged in -stable tree). "Convert the boot-time host ptrace testing from clone to fork. They were essentially doing fork anyway. This cleans up the code a bit, and makes valgrind a bit happier about grinding it."

This patch is an attempt to fix deadlocks discovered in the core dm. The problems boil down to md->lock having to be held in too many places, so I've split it into two: md->suspend_lock and md->io_lock. suspend_lock is now held throughout dm_suspended() as well as dm_resume() and dm_swap_table() so that these functions cannot run concurrently: there's no requirement for that and it added complexity. DMF_FS_LOCKED becomes redundant: DMF_SUSPENDED provides adequate protection. Signed-Off-By:

While booting with SMT disabled in bios, when using acpi srat to setup cpu_to_node[], sparse apic_ids create problems. Without this patch, intel x86_64 boxes with hyperthreading disabled in the bios (and which rely on srat for numa setup) endup having incorrect values in cpu_to_node[] arrays, causing sched domains to be built incorrectly etc. Signed-off-by:

This patch eliminates the GCC4 warning on the x86_64 platform: kernel/sched.c:1824: warning: control may reach end of non-void function 'sched_find_first_bit' being inlined. The change follows the lead of others, i.e. it is guaranteed that at least one of b[0], b[1], or b[2] will have a bit set and evaluate to true. That being said, GCC4.0.0 notices that the code flow does not return anything if b[0], b[1] and b[2] are not true. Since we know better, if it's not b[0] or b[1], it has to be b[2]. Signed-off-by:

Icecream preprocesses c sources locally, and sends the result off to a remote host for compiling. It does not recognize includes at assembler level. The fix is to put the assemberincludes an a separate .s file, which will always be assembled locally. Signed-off-by:

This patch will create machinecheck sysdev directories per CPU. All of the cpus still share the same ctl banks. When compiled with CONFIG_HOTPLUG_CPU, it will also bring up/down sysdev directories as cpus go up/down. I have tested the patch along with CONFIG_HOTPLUG_CPU option on in 2.6.13-rc1 kernel.
