2012-02-03net: bpf_jit: fix divide by 0 generationEric Dumazet
[ Upstream commit d00a9dd21bdf7908b70866794c8313ee8a5abd5c ] Several problems fixed in this patch : 1) Target of the conditional jump in case a divide by 0 is performed by a bpf is wrong. 2) Must 'generate' the full function prologue/epilogue at pass=0, or else we can stop too early in pass=1 if the proglen doesnt change. (if the increase of prologue/epilogue equals decrease of all instructions length because some jumps are converted to near jumps) 3) Change the wrong length detection at the end of code generation to issue a more explicit message, no need for a full stack trace.

2012-02-03ARM: 7296/1: proc-v7.S: remove HARVARD_CACHE preprocessor guardsWill Deacon
commit 612539e81f655f6ac73c7af1da8701c1ee618aee upstream. On v7, we use the same cache maintenance instructions for data lines as for unified lines. This was not the case for v6, where HARVARD_CACHE was defined to indicate the L1 cache topology. This patch removes the erroneous compile-time check for HARVARD_CACHE in proc-v7.S, ensuring that we perform I-side invalidation at boot.

2012-02-03x86/microcode_amd: Add support for CPU family specific container filesAndreas Herrmann
commit 5b68edc91cdc972c46f76f85eded7ffddc3ff5c2 upstream. We've decided to provide CPU family specific container files (starting with CPU family 15h). E.g. for family 15h we have to load microcode_amd_fam15h.bin instead of microcode_amd.bin Rationale is that starting with family 15h patch size is larger than 2KB which was hard coded as maximum patch size in various microcode loaders (not just Linux). Container files which include patches larger than 2KB cause different kinds of trouble with such old patch loaders. Thus we have to ensure that the default container file provides only patches with size less than 2KB.

2012-01-25score: fix off-by-one index into syscall tableDan Rosenberg
commit c25a785d6647984505fa165b5cd84cfc9a95970b upstream. If the provided system call number is equal to __NR_syscalls, the current check will pass and a function pointer just after the system call table may be called, since sys_call_table is an array with total size __NR_syscalls. Whether or not this is a security bug depends on what the compiler puts immediately after the system call table. It's likely that this won't do anything bad because there is an additional NULL check on the syscall entry, but if there happens to be a non-NULL value immediately after the system call table, this may result in local privilege escalation.

2012-01-25ACPI, ia64: Use SRAT table rev to use 8bit or 16/32bit PXM fields (ia64)Kurt Garloff
commit 9f10f6a520deb3639fac78d81151a3ade88b4e7f upstream. In SRAT v1, we had 8bit proximity domain (PXM) fields; SRAT v2 provides 32bits for these. The new fields were reserved before. According to the ACPI spec, the OS must disregrard reserved fields. ia64 did handle the PXM fields almost consistently, but depending on sgi's sn2 platform. This patch leaves the sn2 logic in, but does also use 16/32 bits for PXM if the SRAT has rev 2 or higher. The patch also adds __init to the two pxm accessor functions, as they access __initdata now and are called from an __init function only anyway. Note that the code only uses 16 bits for the PXM field in the processor proximity field; the patch does not address this as 16 bits are more than enough.

commit ae5cd86455381282ece162966183d3f208c6fad7 upstream. This assures that a _CRS reserved host bridge window or window region is not used if it is not addressable by the CPU. The new code either trims the window to exclude the non-addressable portion or totally ignores the window if the entire window is non-addressable. The current code has been shown to be problematic with 32-bit non-PAE kernels on systems where _CRS reserves resources above 4GB.

2012-01-12powerpc: Fix unpaired probe_hcall_entry and probe_hcall_exitLi Zhong
commit e4f387d8db3ba3c2dae4d8bdfe7bb5f4fe1bcb0d upstream. Unpaired calling of probe_hcall_entry and probe_hcall_exit might happen as following, which could cause incorrect preempt count. __trace_hcall_entry => trace_hcall_entry -> probe_hcall_entry => get_cpu_var => preempt_disable __trace_hcall_exit => trace_hcall_exit -> probe_hcall_exit => put_cpu_var => preempt_enable where: A => B and A -> B means A calls B, but => means A will call B through function name, and B will definitely be called. -> means A will call B through function pointer, so B might not be called if the function pointer is not set. So error happens when only one of probe_hcall_entry and probe_hcall_exit get called during a hcall. This patch tries to move the preempt count operations from probe_hcall_entry and probe_hcall_exit to its callers. Reported-by: Paul E.

2012-01-12powerpc/time: Handle wrapping of decrementerAnton Blanchard
commit 37fb9a0231ee43d42d069863bdfd567fca2b61af upstream. When re-enabling interrupts we have code to handle edge sensitive decrementers by resetting the decrementer to 1 whenever it is negative. If interrupts were disabled long enough that the decrementer wrapped to positive we do nothing. This means interrupts can be delayed for a long time until it finally goes negative again. While we hope interrupts are never be disabled long enough for the decrementer to go positive, we have a very good test team that can drive any kernel into the ground. The softlockup data we get back from these fails could be seconds in the future, completely missing the cause of the lockup. We already keep track of the timebase of the next event so use that to work out if we should trigger a decrementer exception.

2012-01-06sparc: Fix handling of orig_i0 wrt. debugging when restarting syscalls.David S. Miller
[ A combination of upstream commits 1d299bc7732c34d85bd43ac1a8745f5a2fed2078 and e88d2468718b0789b4c33da2f7e1cef2a1eee279 ] Although we provide a proper way for a debugger to control whether syscall restart occurs, we run into problems because orig_i0 is not saved and restored properly. Luckily we can solve this problem without having to make debuggers aware of the issue. Across system calls, several registers are considered volatile and can be safely clobbered. Therefore we use the pt_regs save area of one of those registers, %g6, as a place to save and restore orig_i0. Debuggers transparently will do the right thing because they save and restore this register already. Signed-off-by: David S.

2011-12-21xen: only limit memory map to maximum reservation for domain 0.Ian Campbell
commit d3db728125c4470a2d061ac10fa7395e18237263 upstream. d312ae878b6a "xen: use maximum reservation to limit amount of usable RAM" clamped the total amount of RAM to the current maximum reservation. This is correct for dom0 but is not correct for guest domains. In order to boot a guest "pre-ballooned" (e.g. with memory=1G but maxmem=2G) in order to allow for future memory expansion the guest must derive max_pfn from the e820 provided by the toolstack and not the current maximum reservation (which can reflect only the current maximum, not the guest lifetime max). The existing algorithm already behaves this correctly if we do not artificially limit the maximum number of pages for the guest case.

2011-12-21x86, hpet: Immediately disable HPET timer 1 if rtc irq is maskedMark Langsdorf
commit 2ded6e6a94c98ea453a156748cb7fabaf39a76b9 upstream. When HPET is operating in RTC mode, the TN_ENABLE bit on timer1 controls whether the HPET or the RTC delivers interrupts to irq8. When the system goes into suspend, the RTC driver sends a signal to the HPET driver so that the HPET releases control of irq8, allowing the RTC to wake the system from suspend. The switchover is accomplished by a write to the HPET configuration registers which currently only occurs while servicing the HPET interrupt. On some systems, I have seen the system suspend before an HPET interrupt occurs, preventing the write to the HPET configuration register and leaving the HPET in control of the irq8. As the HPET is not active during suspend, it does not generate a wake signal and RTC alarms do not work. This patch forces the HPET driver to immediately transfer control of the irq8 channel to the RTC instead of waiting until the next interrupt event.

2011-12-21thp: add compound tail page _mapcount when mappedYouquan Song
commit b6999b19120931ede364fa3b685e698a61fed31d upstream. With the 3.2-rc kernel, IOMMU 2M pages in KVM works. But when I tried to use IOMMU 1GB pages in KVM, I encountered an oops and the 1GB page failed to be used. The root cause is that 1GB page allocation calls gup_huge_pud() while 2M page calls gup_huge_pmd. If compound pages are used and the page is a tail page, gup_huge_pmd() increases _mapcount to record tail page are mapped while gup_huge_pud does not do that. So when the mapped page is relesed, it will result in kernel oops because the page is not marked mapped. This patch add tail process for compound page in 1GB huge page which keeps the same process as 2M page. Reproduce like: 1. Add grub boot option: hugepagesz=1G hugepages=8 2. mount -t hugetlbfs -o pagesize=1G hugetlbfs /dev/hugepages 3. qemu-kvm -m 2048 -hda os-kvm.img -cpu kvm64 -smp 4 -mem-path /dev/hugepages -net none -device pci-assign,host=07:00.1 kernel BUG at mm/swap.c:114! invalid opcode: 0000 [#1] SMP Call Trace: put_page+0x15/0x37 kvm_release_pfn_clean+0x31/0x36 kvm_iommu_put_pages+0x94/0xb1 kvm_iommu_unmap_memslots+0x80/0xb6 kvm_assign_device+0xba/0x117 kvm_vm_ioctl_assigned_device+0x301/0xa47 kvm_vm_ioctl+0x36c/0x3a2 do_vfs_ioctl+0x49e/0x4e4 sys_ioctl+0x5a/0x7c system_call_fastpath+0x16/0x1b RIP put_compound_page+0xd4/0x168 Signed-off-by: Youquan Song <youquan.song@intel.com> Reviewed-by: Andrea Arcangeli <aarcange@redhat.com> Cc: Andi Kleen <andi@firstfloor.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Since we are running in batched mode (lazy) we don't actually set up the PTE mappings and the kmap_atomic is not done synchronously and ends up trying to dereference a page that has not been set. Looking at kmap_atomic_prot_pfn(), it uses 'arch_flush_lazy_mmu_mode' and doing the same in kmap_atomic_prot() and __kunmap_atomic() makes the problem go away. Interestingly, commit b8bcfe997e4615 ("x86/paravirt: remove lazy mode in interrupts") removed part of this to fix an interrupt issue - but it went to far and did not consider this scenario.

2011-12-09x86/mpparse: Account for bus types other than ISA and PCIBjorn Helgaas
commit 9e6866686bdf2dcf3aeb0838076237ede532dcc8 upstream. In commit f8924e770e04 ("x86: unify mp_bus_info"), the 32-bit and 64-bit versions of MP_bus_info were rearranged to match each other better. Unfortunately it introduced a regression: prior to that change we used to always set the mp_bus_not_pci bit, then clear it if we found a PCI bus. After it, we set mp_bus_not_pci for ISA buses, clear it for PCI buses, and leave it alone otherwise. In the cases of ISA and PCI, there's not much difference. But ISA is not the only non-PCI bus, so it's better to always set mp_bus_not_pci and clear it only for PCI. Without this change, Dan's Dell PowerEdge 4200 panics on boot with a log indicating interrupt routing trouble unless the "noapic" option is supplied. With this change, the machine boots reliably without "noapic".

On revisions of the PL310 prior to r3p2, the Store Buffer does not automatically drain. This can cause normal, non-cacheable writes to be retained when the memory system is idle, leading to suboptimal I/O performance for drivers using coherent DMA. This patch adds an optional wmb() call to the cpu_idle loop. On systems with an outer cache, this causes an explicit flush of the store buffer.

commit c2735391fbc68feae10d6d14e60956c8106e725f upstream. reg | (1 << clk->enable_shift) always evaluates to true. Switch it to & which makes much more sense. Same fix as 13be9f00 (ARM i.MX28: fix bit operation) at a different location.

commit c0a39151a4055332897cba615623d3de2f3896df upstream. Since CONFIG_USB_GADGET_PXA27X and other macros are renamed to CONFIG_USB_PXA27X. Update them in arch/arm/mach-pxa and arch/arm/configs to keep consistent.
