We initialize the routing metrics with the values cached on the inetpeer in rt_init_metrics(). So if we have the metrics cached on the inetpeer, we ignore the user configured fib_metrics. To fix this issue, we replace the old tree with a fresh initialized inet_peer_base. The old tree is removed later with a delayed work queue.

When modifying IP addresses or ports on a UDP packet we don't correctly follow the rules for unchecksummed packets.

2012-03-07dm raid: set MD_CHANGE_DEVS when rebuildingJonathan E Brassow1-6/+10
The 'rebuild' parameter is used to rebuild individual devices in an array (e.g. resynchronize a RAID1 device or recalculate a parity device in higher RAID). The MD_CHANGE_DEVS flag must be set when this parameter is given in order to write out the superblocks and make the change take immediate effect. The code that handles new devices in super_load already sets MD_CHANGE_DEVS and 'FirstUse'. (The 'FirstUse' flag was being set as a special case for rebuilds in super_init_validation.) Add a condition for rebuilds in super_load to take care of both flags without the special case in 'super_init_validation'.

2012-03-07Revert "CPU hotplug, cpusets, suspend: Don't touch cpusets during ↵Linus Torvalds1-2/+2
suspend/resume" This reverts commit 8f2f748b0656257153bcf0941df8d6060acc5ca6. It causes some odd regression that we have not figured out, and it's too late in the -rc series to try to figure it out now. As reported by Konstantin Khlebnikov, it causes consistent hangs on his laptop (Thinkpad x220: 2x cores + HT). They can be avoided by adding calls to "rebuild_sched_domains();" in cpuset_cpu_[in]active() for the CPU_{ONLINE/DOWN_FAILED/DOWN_PREPARE}_FROZEN cases, but it's not at all clear why, and it makes no sense. Konstantin's config doesn't even have CONFIG_CPUSETS enabled, just to make things even more interesting. So it's not the cpusets, it's just the scheduling domains. So until this is understood, revert.

2012-03-07ARM: 7358/1: perf: add PMU hotplug notifierLorenzo Pieralisi1-0/+23
When a CPU is taken out of reset, either cold booted or hotplugged in, some of its PMU registers can contain UNKNOWN values. This patch adds a hotplug notifier to ARM core perf code so that upon CPU restart the PMU unit is reset and becomes ready to use again.

2012-03-07ARM: 7357/1: perf: fix overflow handling for xscale2 PMUsWill Deacon1-2/+8
xscale2 PMUs indicate overflow not via the PMU control register, but by a separate overflow FLAG register instead. This patch fixes the xscale2 PMU code to use this register to detect to overflow and ensures that we clear any pending overflow when disabling a counter.

2012-03-07ARM: 7356/1: perf: check that we have an event in the PMU IRQ handlersWill Deacon3-18/+12
The PMU IRQ handlers in perf assume that if a counter has overflowed then perf must be responsible. In the paranoid world of crazy hardware, this could be false, so check that we do have a valid event before attempting to dereference NULL in the interrupt path.

2012-03-07ARM: 7355/1: perf: clear overflow flag when disabling counter on ARMv7 PMUWill Deacon1-0/+5
When disabling a counter on an ARMv7 PMU, we should also clear the overflow flag in case an overflow occurred whilst stopping the counter. This prevents a spurious overflow being picked up later and leading to either false accounting or a NULL dereference.

2012-03-07ARM: 7354/1: perf: limit sample_period to half max_period in non-sampling modeWill Deacon5-16/+16
On ARM, the PMU does not stop counting after an overflow and therefore IRQ latency affects the new counter value read by the kernel. This is significant for non-sampling runs where it is possible for the new value to overtake the previous one, causing the delta to be out by up to max_period events. Commit a737823d ("ARM: 6835/1: perf: ensure overflows aren't missed due to IRQ latency") attempted to fix this problem by allowing interrupt handlers to pass an overflow flag to the event update function, causing the overflow calculation to assume that the counter passed through zero when going from prev to new. Unfortunately, this doesn't work when overflow occurs on the perf_task_tick path because we have the flag cleared and end up computing a large negative delta. This patch removes the overflow flag from armpmu_event_update and instead limits the sample_period to half of the max_period for non-sampling profiling runs.

Pull networking fixes from David Miller: 1) TCP can chop up SACK'd SKBs below below the unacked send sequence and that breaks lots of stuff. Fix from Neal Cardwell. 2) There is code in ipv6 to properly join and leave the all-routers multicast code when the forwarding setting is changed, but once forwarding is turned on, we don't do the join for newly registered devices. Fix from Li Wei. 3) Netfilter's NAT module autoload in ctnetlink drops a spinlock around a sleeping call, problem is this code path doesn't actually hold that lock. Fix from Pablo Neira Ayuso. 4) TG3 uses the wrong interfaces to hook into the new byte queue limit support. It uses the device level interfaces, which is fine for single queue devices, but on more recent chips this driver supports multiqueue so we have to use the multiqueue BQL APIs.

It turns out that test-compiling this file on x86-64 doesn't really help, because much of it is x86-32-specific.

2012-03-06vm: avoid using find_vma_prev() unnecessarilyLinus Torvalds4-4/+9
Several users of "find_vma_prev()" were not in fact interested in the previous vma if there was no primary vma to be found either. And in those cases, we're much better off just using the regular "find_vma()", and then "prev" can be looked up by just checking vma->vm_prev. The find_vma_prev() semantics are fairly subtle (see Mikulas' recent commit 83cd904d271b: "mm: fix find_vma_prev"), and the whole "return prev by reference" means that it generates worse code too. Thus this "let's avoid using this inconvenient and clearly too subtle interface when we don't really have to" patch.

2012-03-06mm: fix find_vma_prevMikulas Patocka1-2/+10
Commit 6bd4837de96e ("mm: simplify find_vma_prev()") broke memory management on PA-RISC. After application of the patch, programs that allocate big arrays on the stack crash with segfault, for example, this will crash if compiled without optimization: int main() { char array[200000]; array[199999] = 0; return 0; } The reason is that PA-RISC has up-growing stack and the stack is usually the last memory area. In the above example, a page fault happens above the stack. Previously, if we passed too high address to find_vma_prev, it returned NULL and stored the last VMA in *pprev. After "simplify find_vma_prev" change, it stores NULL in *pprev. Consequently, the stack area is not found and it is not expanded, as it used to be before the change. This patch restores the old behavior and makes it return the last VMA in *pprev if the requested address is higher than address of any other VMA.

2012-03-06genirq: Clear action->thread_mask if IRQ_ONESHOT is not setThomas Gleixner1-6/+38
Xommit ac5637611(genirq: Unmask oneshot irqs when thread was not woken) fails to unmask when a !IRQ_ONESHOT threaded handler is handled by handle_level_irq. This happens because thread_mask is or'ed unconditionally in irq_wake_thread(), but for !IRQ_ONESHOT interrupts never cleared. So the check for !desc->thread_active fails and keeps the interrupt disabled. Keep the thread_mask zero for !IRQ_ONESHOT interrupts. Document the thread_mask magic while at it.
