Fix robust PI-futexes to be properly unlocked on unexpected exit. For this to work the kernel has to know whether a futex is a PI or a non-PI one, because the semantics are different. Since the space in relevant glibc data structures is extremely scarce, the best solution is to encode the 'PI' information in bit 0 of the robust list pointer. Existing (non-PI) glibc robust futexes have this bit always zero, so the ABI is kept. New glibc with PI-robust-futexes will set this bit.

The dwarf2 unwinder currently often gets stuck because a lot of assembly code doesn't have proper dwarf2 annotiation yet. This currently often happens with __down. Should fix this by adding proper dwarf2 annotation to all inline assembly. However until that's done we need a quick fix for 2.6.18 to avoid incomplete backtraces. So when this happens dump the rest of the stack with the old unwinder instead of silently not dumping it. There was already a optional "both" mode that dumped both, but that was too ugly. I also clarified the headers for the different backtraces a bit. Also add a clear error message for missing dwarf2 annotation that people can work on. And I removed a dead variable left over from Ingo's changes. Cc: mingo@elte.hu Cc: jbeulich@novell.com Signed-off-by: NAndi Kleen <ak@suse.de> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

In x86_64 platform, INT1 and INT3 trap stack is IST stack called DEBUG_STACK, when INT1/INT3 trap happens, system will switch to DEBUG_STACK by hardware. Current DEBUG_STACK size is 4K, when int1/int3 trap happens, kernel will minus current DEBUG_STACK IST value by 4k. But if int3/int1 trap is nested, it will destroy other vector's IST stack. This patch modifies this, it sets DEBUG_STACK size as 8K and allows two level of nested int1/int3 trap. Kprobe DEBUG_STACK may be nested, because kprobe handler may be probed by other kprobes. Thanks jbeulich for pointing out error in the first patch. [AK: nested kprobes are pretty dubious. Hopefully one nest will be enough. This will cost 8K per CPU (4K more than before)] Signed-off-by: Nbibo, mao <bibo.mao@intel.com> Signed-off-by: NAndi Kleen <ak@suse.de> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

When int 0x80 is called from long mode r8-r11 would leak out of the kernel (or rather they would be filled with some values from the kernel stack). I don't think it's a security issue because the values come from the fixed stack frame which should be near always user registers from a previous interrupt. Still better fix it. Longer term the register save macros need to be cleaned up to avoid such mistakes in the future. Original analysis from Richard Brunner, fix by me.

Fixes a obscure user space triggerable crash during oprofiling. Oprofile calls profile_pc from NMIs even when user_mode(regs) is not true and the program counter is inside the kernel lock section. This opens a race - when a user program jumps to a kernel lock address and a NMI happens before the illegal page fault exception is raised and the program has a unmapped esp or ebp then the kernel could oops. NMIs have a higher priority than exceptions so that could happen. Add user_mode checks to i386/x86-64 profile_pc to prevent that.

In special conditions where a subchannel rejects the HALT I/O- instruction with a busy indication (cc 2), I/O may stall. I/O request termination logic retries HALT I/O indefinitely because it expects HALT I/O to alter the subchannel status which is not true when cc 2 is returned. In case of a busy indication, try CLEAR I/O instruction immediately. Signed-off-by: NPeter Oberparleiter <peter.oberparleiter@de.ibm.com> Signed-off-by: NMartin Schwidefsky <schwidefsky@de.ibm.com>

This fixes three drivers to compile again after my patch that removes the data_cmnd member from struct scsi_cmnd. The fas216 change is trivial, it should have been using ->cmnd all the time. NCR53C9 (which seem to be mostly duplicate driver with esp.c!) is doing something odd, it should only have looked at ->cmnd before not the saved copy that is kept for the error handlers sake. Note that it really should deal with the sync setting themselves but use the generic domain validation code that get this right - but that's for later let's push this simple compile fix for now. And sorry for the late fix for this, I have been busy with OLS and associated activities last week. Signed-off-by: NChristoph Hellwig <hch@lst.de> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

The patch below moves the cpu hotplugging higher up in the cpufreq layering; this is needed to avoid recursive taking of the cpu hotplug lock and to otherwise detangle the mess. The new rules are: 1. you must do lock_cpu_hotplug() around the following functions: __cpufreq_driver_target __cpufreq_governor (for CPUFREQ_GOV_LIMITS operation only) __cpufreq_set_policy 2. governer methods (.governer) must NOT take the lock_cpu_hotplug() lock in any way; they are called with the lock taken already 3. if your governer spawns a thread that does things, like calling __cpufreq_driver_target, your thread must honor rule #1. 4. the policy lock and other cpufreq internal locks nest within the lock_cpu_hotplug() lock. I'm not entirely happy about how the __cpufreq_governor rule ended up (conditional locking rule depending on the argument) but basically all callers pass this as a constant so it's not too horrible. The patch also removes the cpufreq_governor() function since during the locking audit it turned out to be entirely unused (so no need to fix it) The patch works on my testbox, but it could use more testing (otoh... it can't be much worse than the current code) Signed-off-by: NArjan van de Ven <arjan@linux.intel.com> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

From: Tetsuo Handa from-linux-kernel@i-love.sakura.ne.jp The recvmsg() for raw socket seems to return random u16 value from the kernel stack memory since port field is not initialized.
