2015-09-04crypto: ghash-clmulni: specify context size for ghash async algorithmAndrey Ryabinin
Currently context size (cra_ctxsize) doesn't specified for ghash_async_alg. Which means it's zero. Thus crypto_create_tfm() doesn't allocate needed space for ghash_async_ctx, so any read/write to ctx (e.g. in ghash_async_init_tfm()) is not valid.

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Will Deacon: - Support for new architectural features introduced in ARMv8.1: * Privileged Access Never (PAN) to catch user pointer dereferences in the kernel * Large System Extension (LSE) for building scalable atomics and locks (depends on locking/arch-atomic from tip, which is included here) * Hardware Dirty Bit Management (DBM) for updating clean PTEs automatically - Move our PSCI implementation out into drivers/firmware/, where it can be shared with arch/arm/. RMK has also pulled this component branch and has additional patches moving arch/arm/ over. MAINTAINERS is updated accordingly. - Better BUG implementation based on the BRK instruction for trapping - Leaf TLB invalidation for unmapping user pages - Support for PROBE_ONLY PCI configurations - Various cleanups and non-critical fixes, including: * Always flush FP/SIMD state over exec() * Restrict memblock additions based on range of linear mapping * Ensure *(LIST_POISON) generates a fatal fault * Context-tracking syscall return no longer corrupts return value when not forced on. * Alternatives patching synchronisation/stability improvements * Signed sub-word cmpxchg compare fix (tickled by HAVE_CMPXCHG_LOCAL) * Force SMP=y * Hide direct DCC access from userspace * Fix EFI stub memory allocation when DRAM starts at 0x0 * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (92 commits) arm64: flush FP/SIMD state correctly after execve() arm64: makefile: fix perf_callchain.o kconfig dependency arm64: set MAX_MEMBLOCK_ADDR according to linear region size of/fdt: make memblock maximum physical address arch configurable arm64: Fix source code file path in comments arm64: entry: always restore x0 from the stack on syscall return arm64: mdscr_el1: avoid exposing DCC to userspace arm64: kconfig: Move LIST_POISON to a safe value arm64: Add __exception_irq_entry definition for function graph arm64: mm: ensure patched kernel text is fetched from PoU arm64: alternatives: ensure secondary CPUs execute ISB after patching arm64: make ll/sc __cmpxchg_case_##name asm consistent arm64: dma-mapping: Simplify pgprot handling arm64: restore cpu suspend/resume functionality ARM64: PCI: do not enable resources on PROBE_ONLY systems arm64: cmpxchg: truncate sub-word signed types before comparison arm64: alternative: put secondary CPUs into polling loop during patch arm64/Documentation: clarify wording regarding memory below the Image arm64: lse: fix lse cmpxchg code indentation arm64: remove redundant object file list ...
2015-09-04kbuild: Fix clang detectionMichal Marek
We cannot detect clang before including the arch Makefile, because that can set the default cross compiler. We also cannot detect clang after including the arch Makefile, because powerpc wants to know about clang. Solve this by using an deferred variable. This costs us a few shell invocations, but this is only a constant number.

2015-09-04deb-pkg: add source packageRiku Voipio
Make deb-pkg build both source and binary package like make rpm-pkg does. For people who only need binary kernel package, there is now bindeb-pkg target, same target also used to build the .deb files if built from the source package using dpkg-buildpackage. Generated source package will build the same kernel .config than what was available for make deb-pkg. The name of the source package can be set with KDEB_SOURCENAME enviroment variable. The source package is useful for GPL compliance, or for feeding to a automated debian package builder.

When processing queued messages in the panic context, IPMI driver tries to do it without any locking to avoid deadlocks. However, this means we can touch a corrupted list if the kernel panicked while manipulating the list. Fortunately, current `add-tail and del-from-head' style implementation won't touch the corrupted part, but it is inherently risky. To get rid of the risk, this patch re-initializes the message lists on panic if the related spinlock has already been acquired. As the result, we may lose queued messages, but it's not so painful. Dropping messages on the received message list is also less problematic because no one can respond the received messages.

2015-09-03ipmi: Don't flush messages in sender() in run-to-completion modeHidehiro Kawai
When flushing queued messages in run-to-completion mode, smi_event_handler() is recursively called. flush_messages() smi_event_handler() handle_transaction_done() deliver_recv_msg() ipmi_smi_msg_received() smi_recv_tasklet() sender() flush_messages() smi_event_handler() ... The depth of the recursive call depends on the number of queued messages, so it can cause a stack overflow if many messages have been queued. To solve this problem, this patch removes flush_messages() from sender()@ipmi_si_intf.c. Instead, add flush_messages() to caller side of sender() if needed. Additionally, to implement this, add new handler flush_messages to struct ipmi_smi_handlers. Signed-off-by: Hidehiro Kawai <hidehiro.kawai.ez@hitachi.com> Fixed up a comment and some spacing issues.

2015-09-03ipmi/powernv: Fix potential invalid pointer dereferenceNeelesh Gupta
If the OPAL call to receive the ipmi message fails, then we free up the smi message and return. But, the driver still holds the reference to old smi message in the 'cur_msg' which can potentially be accessed later and freed again leading to kernel oops. To fix it up, The kernel driver should reset the 'cur_msg' and send reply to the user in addition to freeing the message.

2015-09-03ipmi: Convert the IPMI SI ACPI handling to a platform deviceCorey Minyard
The IPMI SI driver was using direct PNP, but that was not really ideal because the IPMI device is a platform device. There was some special handling in the acpi_pnp.c code for making this work, but that was breaking ACPI handling for the IPMI SSIF driver. So without this patch there were significant issues getting the SSIF driver to work with ACPI. So use a platform device for ACPI detection and remove the entry from acpi_pnp.c.

2015-09-03IB/srp: Fix possible protection faultSagi Grimberg
srp_destroy_qp is designed to indicate we are safe to continue with freeing the channel resources by modifying the qp error state, posting a dummy wr on the queue-pair and waiting for it to flush. This also holds for the channel registration pool as we are unmapping the memory region when handling a scsi response. Destroying the channel registration pool before we make sure we processed all the inflight IO might introduce a use-after-free of the registration pool. This use-after-free is demonstrated in the stack trace below where srp is trying to unmap a used FMR after the fmr_pool was already destroyed. general protection fault: 0000 [#1] SMP RIP: 0010:[<ffffffff8151121b>] [<ffffffff8151121b>] _raw_spin_lock_irqsave+0x1b/0x50 Call Trace: [<ffffffffa055d88a>] ib_fmr_pool_unmap+0x1a/0xb0 [ib_core] [<ffffffffa06c00ed>] srp_unmap_data.isra.28+0x17d/0x250 [ib_srp] [<ffffffffa06c01eb>] srp_free_req+0x2b/0x60 [ib_srp] [<ffffffffa06c0c94>] srp_recv_completion+0x174/0x580 [ib_srp] [<ffffffffa04580fe>] mlx4_eq_int+0x4de/0xe50 [mlx4_core] [<ffffffffa0458b00>] mlx4_msi_x_interrupt+0x10/0x20 [mlx4_core] [<ffffffff810abc45>] handle_irq_event_percpu+0x35/0x1b0 [<ffffffff810abdf2>] handle_irq_event+0x32/0x50 [<ffffffff810ae5cf>] handle_edge_irq+0x6f/0x120 [<ffffffff8100455a>] handle_irq+0x1a/0x30 [<ffffffff8151b475>] do_IRQ+0x45/0xb0 [<ffffffff8151162d>] common_interrupt+0x6d/0x6d [<ffffffff813e4d2f>] cpuidle_enter_state+0x4f/0xc0 [<ffffffff813e4e6c>] cpuidle_idle_call+0xcc/0x210 [<ffffffff8100b9ea>] arch_cpu_idle+0xa/0x30 [<ffffffff810ab1e1>] cpu_startup_entry+0xe1/0x270 [<ffffffff81030b3a>] start_secondary+0x21a/0x2c0 Reported-by: Eliott Kespi <eliottk@mellanox.com> Signed-off-by: Sagi Grimberg <sagig@mellanox.com> Signed-off-by: Bart Van Assche <bart.vanassche@sandisk.com> Signed-off-by: Doug Ledford <dledford@redhat.com>

Since patch series "Demux IB CM requests in the rdma_cm module" the P_Key index is taken from the work completion rather than the message itself. The HCA provides us with the message P_Key. In order to provide the P_Key index, we need to look it up.
