2013-11-05crypto: s390 - Fix aes-cbc IV corruptionHerbert Xu1-7/+12
The cbc-aes-s390 algorithm incorrectly places the IV in the tfm data structure. As the tfm is shared between multiple threads, this introduces a possibility of data corruption. This patch fixes this by moving the parameter block containing the IV and key onto the stack (the block is 48 bytes long). The same bug exists elsewhere in the s390 crypto system and they will be fixed in subsequent patches. Cc: [email protected] Signed-off-by: Herbert Xu <[email protected]>
2013-11-05arm64: module: ensure instruction is little-endian before manipulationWill Deacon1-1/+4
Relocations that require an instruction immediate to be re-encoded must ensure that the instruction pattern is represented in a little-endian format for the manipulation code to work correctly. This patch converts the loaded instruction into native-endianess prior to encoding and then converts back to little-endian byteorder before updating memory.

2013-11-05arm64: fix access to preempt_count from assembly codeMarc Zyngier1-11/+11
preempt_count is defined as an int. Oddly enough, we access it as a 64bit value. Things become interesting when running a BE kernel, and looking at the current CPU number, which is stored as an int next to preempt_count. Like in a per-cpu interrupt handler, for example... Using a 32bit access fixes the issue for good. Cc: Matthew Leach <[email protected]> Signed-off-by: Marc Zyngier <[email protected]> Signed-off-by: Catalin Marinas <[email protected]>

2013-11-04s390/mm,tlb: correct tlb flush on page table upgradeMartin Schwidefsky6-51/+21
The IDTE instruction used to flush TLB entries for a specific address space uses the address-space-control element (ASCE) to identify affected TLB entries. The upgrade of a page table adds a new top level page table which changes the ASCE. The TLB entries associated with the old ASCE need to be flushed and the ASCE for the address space needs to be replaced synchronously on all CPUs which currently use it. The concept of a lazy ASCE update with an exception handler is broken. Signed-off-by: Martin Schwidefsky <[email protected]>

2013-11-03KVM: x86: fix emulation of "movzbl %bpl, %eax"Paolo Bonzini1-1/+4
When I was looking at RHEL5.9's failure to start with unrestricted_guest=0/emulate_invalid_guest_state=1, I got it working with a slightly older tree than kvm.git. I now debugged the remaining failure, which was introduced by commit 660696d1 (KVM: X86 emulator: fix source operand decoding for 8bit mov[zs]x instructions, 2013-04-24) introduced a similar mis-emulation to the one in commit 8acb4207 (KVM: fix sil/dil/bpl/spl in the mod/rm fields, 2013-05-30). The incorrect decoding occurs in 8-bit movzx/movsx instructions whose 8-bit operand is sil/dil/bpl/spl. Needless to say, "movzbl %bpl, %eax" does occur in RHEL5.9's decompression prolog, just a handful of instructions before finally giving control to the decompressed vmlinux and getting out of the invalid guest state. Because OpMem8 bypasses decode_modrm, the same handling of the REX prefix must be applied to OpMem8.

2013-11-02ARC: Incorrect mm reference used in vmalloc fault handlerVineet Gupta1-3/+3
A vmalloc fault needs to sync up PGD/PTE entry from init_mm to current task's "active_mm". ARC vmalloc fault handler however was using mm. A vmalloc fault for non user task context (actually pre-userland, from init thread's open for /dev/console) caused the handler to deref NULL mm (for mm->pgd) The reasons it worked so far is amazing: 1. By default (!SMP), vmalloc fault handler uses a cached value of PGD. In SMP that MMU register is repurposed hence need for mm pointer deref. 2. In pre-3.12 SMP kernel, the problem triggering vmalloc didn't exist in pre-userland code path - it was introduced with commit 20bafb3d23d108bc "n_tty: Move buffers into n_tty_data" Signed-off-by: Vineet Gupta <[email protected]> Cc: Gilad Ben-Yossef <[email protected]> Cc: Noam Camus <[email protected]> Cc: [email protected] #3.10 and 3.11 Cc: Peter Hurley <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

2013-10-31ARM: 7805/1: mm: change max*pfn to include the physical offset of memorySantosh Shilimkar2-6/+12
Most of the kernel code assumes that max*pfn is maximum pfns because the physical start of memory is expected to be PFN0. Since this assumption is not true on ARM architectures, the meaning of max*pfn is number of memory pages. This is done to keep drivers happy which are making use of of these variable to calculate the dma bounce limit using dma_mask. Now since we have a architecture override possibility for DMAable maximum pfns, lets make meaning of max*pfns as maximum pnfs on ARM as well.

2013-10-31ARM: DMA-API: better handing of DMA masks for coherent allocationsRussell King3-6/+49
We need to start treating DMA masks as something which is specific to the bus that the device resides on, otherwise we're going to hit all sorts of nasty issues with LPAE and 32-bit DMA controllers in >32-bit systems, where memory is offset from PFN 0. In order to start doing this, we convert the DMA mask to a PFN using the device specific dma_to_pfn() macro. This is the reverse of the pfn_to_dma() macro which is used to get the DMA address for the device. This gives us a PFN mask, which we can then check against the PFN limit of the DMA zone.

2013-10-31KVM: x86: fix KVM_SET_XCRS loopPaolo Bonzini1-2/+2
The loop was always using 0 as the index. This means that any rubbish after the first element of the array went undetected. It seems reasonable to assume that no KVM userspace did that. Reviewed-by: Gleb Natapov <[email protected]> Signed-off-by: Paolo Bonzini <[email protected]>
2013-10-31KVM: x86: fix KVM_SET_XCRS for CPUs that do not support XSAVEPaolo Bonzini1-1/+10
The KVM_SET_XCRS ioctl must accept anything that KVM_GET_XCRS could return. XCR0's bit 0 is always 1 in real processors with XSAVE, and KVM_GET_XCRS will always leave bit 0 set even if the emulated processor does not have XSAVE. So, KVM_SET_XCRS must ignore that bit when checking for attempts to enable unsupported save states. Reviewed-by: Gleb Natapov <[email protected]> Signed-off-by: Paolo Bonzini <[email protected]>
