2007-09-26Revert "x86-64: Disable local APIC timer use on AMD systems with C1E"Linus Torvalds
This reverts commit e66485d747505e9d960b864fc6c37f8b2afafaf0, since Rafael Wysocki noticed that the change only works for his in -mm, not in mainline (and that both "noapictimer" _and_ "apicmaintimer" are broken on his hardware, but that's apparently not a regression, just a symptom of the same issue that causes the automatic apic timer disable to not work). It turns out that it really doesn't work correctly on x86-64, since x86-64 doesn't use the generic clock events for timers yet. Thanks to Rafal for testing, and here's the ugly details on x86-64 as per Thomas: "I just looked into the code and the logic vs. noapictimer on SMP is completely broken. On i386 the noapictimer option not only disables the local APIC timer, it also registers the CPUs for broadcasting via IPI on SMP systems. The x86-64 code uses the broadcast only when the local apic timer is active, i.e. "noapictimer" is not on the command line. This defeats the whole purpose of "noapictimer". It should be there to make boxen work, where the local APIC timer actually has a hardware problem, e.g. the nx6325. The current implementation of x86_64 only fixes the ACPI c-states related problem where the APIC timer stops in C3(2), nothing else. On nx6325 and other AMD X2 equipped systems which have the C1E enabled we run into the following: PIT keeps jiffies (and the system) running, but the local APIC timer interrupts can get out of sync due to this C1E effect. I don't think this is a critical problem, but it is wrong nevertheless. I think it's safe to revert the C1E patch and postpone the fix to the clock events conversion." On further reflection, Thomas noted: "It's even worse than I thought on the first check: "noapictimer" on the command line of an SMP box prevents _ONLY_ the boot CPU apic timer from being used. But the secondary CPU is still unconditionally setting up the APIC timer and uses the non calibrated variable calibration_result, which is of course 0, to setup the APIC timer. Wreckage guaranteed." so we'll just have to wait for the x86 merge to hopefully fix this up for x86-64. Tested-and-requested-by: Rafael J.

2007-09-26[x86 setup] Handle case of improperly terminated E820 chainH. Peter Anvin
At least one system (a Geode system with a Digital Logic BIOS) has been found which suddenly stops reporting the SMAP signature when reading the E820 memory chain. We can't know what, exactly, broke in the BIOS, so if we detect this situation, declare the E820 data unusable and fall back to E801. Also, revert to original behavior of always probing all memory methods; that way all the memory information is available to the kernel. Signed-off-by: H.

2007-09-26x86-64: Disable local APIC timer use on AMD systems with C1EThomas Gleixner
commit 3556ddfa9284a86a59a9b78fe5894430f6ab4eef titled [PATCH] x86-64: Disable local APIC timer use on AMD systems with C1E solves a problem with AMD dual core laptops e.g. HP nx6325 (Turion 64 X2) with C1E enabled: When both cores go into idle at the same time, then the system switches into C1E state, which is basically the same as C3. This stops the local apic timer. This was debugged right after the dyntick merge on i386 and despite the patch title it fixes only the 32 bit path. x86_64 is still missing this fix. It seems that mainline is not really affected by this issue, as the PIT is running and keeps jiffies incrementing, but that's just waiting for trouble. -mm suffers from this problem due to the x86_64 high resolution timer patches. This is a quick and dirty port of the i386 code to x86_64. I spent quite a time with Rafael to debug the -mm / hrt wreckage until someone pointed us to this. I really had forgotten that we debugged this half a year ago already. Sigh, is it just me or is there something yelling arch/x86 into my ear?

2007-09-26NLM: Fix a circular lock dependency in lockdTrond Myklebust
The problem is that the garbage collector for the 'host' structures nlm_gc_hosts(), holds nlm_host_mutex while calling down to nlmsvc_mark_resources, which, eventually takes the file->f_mutex. We cannot therefore call nlmsvc_lookup_host() from within nlmsvc_create_block, since the caller will already hold file->f_mutex, so the attempt to grab nlm_host_mutex may deadlock. Fix the problem by calling nlmsvc_lookup_host() outside the file->f_mutex. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-09-26Add explicit zeroing to "envp" array in device 'show' methodLinus Torvalds
As Stephen Hemminger says, this is a "belt and suspenders" patch that zeroes the envp array at allocation time, even though all the users should NULL-terminate it anyway (and we've hopefully fixed everybody that doesn't do that). And we'll apparently clean the whole envp thing up for 2.6.24 anyway. But let's just be robust, and do both this *and* make sure that all users are doing the right thing.

2007-09-25SCTP : Add paramters validity check for ASCONF chunkWei Yongjun
If ADDIP is enabled, when an ASCONF chunk is received with ASCONF paramter length set to zero, this will cause infinite loop. By the way, if an malformed ASCONF chunk is received, will cause processing to access memory without verifying. This is because of not check the validity of parameters in ASCONF chunk.

2007-09-25SCTP: Discard OOTB packetes with bundled INIT early.Vlad Yasevich
RFC 4460 and future RFC 4960 (2960-bis) specify that packets with bundled INIT chunks need to be dropped. We currenlty do that only after processing any leading chunks. For OOTB chunks, since we already walk the entire packet, we should discard packets with bundled INITs. There are other chunks chunks that MUST NOT be bundled, but the spec is silent on theire treatment. Thus, we'll leave their teatment alone for the moment.
