perf/x86/intel: Fix large period handling on Broadwell CPUs

by Jim Mattson

I'd like to nominate commit f605cfca8c39 ("perf/x86/intel: Fix large period handling on Broadwell CPUs") for backport to the affected stable Linux releases. (The bug was introduced in 4.1.) Because of this bug, the NMI watchdog timer may fire spuriously on Broadwell systems, resulting in a hard lockup panic when there is, in fact, no lockup.

[PATCH 1/6] ext4: sysfs: print ext4_super_block fields as little-endian

by Arnd Bergmann

While working on extended rand for last_error/first_error timestamps, I noticed that the endianess is wrong, we access the little-endian fields in struct ext4_super_block as native-endian when we print them. This adds a special case in ext4_attr_show() and ext4_attr_store() to byteswap the superblock fields if needed. In older kernels, this code was part of super.c, it got moved to sysfs.c in linux-4.4.

[tip:x86/pti] x86/spectre_v1: Disable compiler optimizations over array_index_mask_nospec()

by tip-bot for Dan Williams

Mark explains: "The volatile will inhibit *some* cases where the compiler could lift the array_index_nospec() call out of a branch, e.g. where there are multiple invocations of array_index_nospec() with the same arguments: if (idx < foo) { idx1 = array_idx_nospec(idx, foo) do_something(idx1); } < some other code > if (idx < foo) { idx2 = array_idx_nospec(idx, foo); do_something_else(idx2); } ... since the compiler can determine that the two invocations yield the same result, and reuse the first result (likely the same register as idx was in originally) for the second branch, effectively re-writing the above as: if (idx < foo) { idx = array_idx_nospec(idx, foo); do_something(idx); } < some other code > if (idx < foo) { do_something_else(idx); } ... if we don't take the first branch, then speculatively take the second, we lose the nospec protection.

[PATCH 2/3] usb: typec: ucsi: acpi: Workaround for cache mode issue

by Heikki Krogerus

This fixes an issue where the driver fails with an error: ioremap error for 0x3f799000-0x3f79a000, requested 0x2, got 0x0 On some platforms the UCSI ACPI mailbox SystemMemory Operation Region may be setup before the driver has been loaded. That will lead into the driver failing to map the mailbox region, as it has been already marked as write-back memory. acpi_os_ioremap() for x86 uses ioremap_cache() unconditionally. When the issue happens, the embedded controller has a pending query event for the UCSI notification right after boot-up which causes the operation region to be setup before UCSI driver has been loaded. The fix is to notify acpi core that the driver is about to access memory region which potentially overlaps with an operation region right before mapping it. acpi_release_memory() will check if the memory has already been setup (mapped) by acpi core, and deactivate it (unmap) if it has. The driver is then able to map the memory with ioremap_nocache() and set the memtype to uncached for the region.

[PATCH 1/3] acpi: Add helper for deactivating memory region

by Heikki Krogerus

Sometimes memory resource may be overlapping with SystemMemory Operation Region by design, for example if the memory region is used as a mailbox for communication with a firmware in the system. One occasion of such mailboxes is USB Type-C Connector System Software Interface (UCSI). With regions like that, it is important that the driver is able to map the memory with the requirements it has. For example, the driver should be allowed to map the memory as non-cached memory. However, if the operation region has been accessed before the driver has mapped the memory, the memory has been marked as write-back by the time the driver is loaded. That means the driver will fail to map the memory if it expects non-cached memory.

[PATCH 2/5] xhci: Fix kernel oops in trace_xhci_free_virt_device

by Mathias Nyman

From: Zhengjun Xing <zhengjun.xing(a)linux.intel.com> commit 44a182b9d177 ("xhci: Fix use-after-free in xhci_free_virt_device") set dev->udev pointer to NULL in xhci_free_dev(), it will cause kernel panic in trace_xhci_free_virt_device. This patch reimplement the trace function trace_xhci_free_virt_device, remove dev->udev dereference and added more useful parameters to show in the trace function,it also makes sure dev->udev is not NULL before calling trace_xhci_free_virt_device. This issue happened when xhci-hcd trace is enabled and USB devices hot plug test. Original use-after-free patch went to stable so this needs so be applied there as well.

+ slub-track-number-of-slabs-irrespective-of-config_slub_debug.patch added to -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: slub: track number of slabs irrespective of CONFIG_SLUB_DEBUG has been added to the -mm tree. Its filename is slub-track-number-of-slabs-irrespective-of-config_slub_debug.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/slub-track-number-of-slabs-irrespe… and later at http://ozlabs.org/~akpm/mmotm/broken-out/slub-track-number-of-slabs-irrespe… Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Shakeel Butt <shakeelb(a)google.com> Subject: slub: track number of slabs irrespective of CONFIG_SLUB_DEBUG For !CONFIG_SLUB_DEBUG, SLUB does not maintain the number of slabs allocated per node for a kmem_cache. Thus, slabs_node() in __kmem_cache_empty(), __kmem_cache_shrink() and __kmem_cache_destroy() will always return 0 for such config. This is wrong and can cause issues for all users of these functions. In fact in [1] Jason has reported a system crash while using SLUB without CONFIG_SLUB_DEBUG. The reason was the usage of slabs_node() by __kmem_cache_empty(). The right solution is to make slabs_node() work even for !CONFIG_SLUB_DEBUG. The commit 0f389ec63077 ("slub: No need for per node slab counters if !SLUB_DEBUG") had put the per node slab counter under CONFIG_SLUB_DEBUG because it was only read through sysfs API and the sysfs API was disabled on !CONFIG_SLUB_DEBUG. However the users of the per node slab counter assumed that it will work in the absence of CONFIG_SLUB_DEBUG. So, make the counter work for !CONFIG_SLUB_DEBUG. Please note that f9e13c0a5a33 ("slab, slub: skip unnecessary kasan_cache_shutdown()") exposed this issue but it is present even before.

[PATCH] MIPS: Always use -march=<arch>, not -<arch> shortcuts

by Paul Burton

The VDSO Makefile filters CFLAGS to select a subset which it uses whilst building the VDSO ELF. One of the flags it allows through is the -march= flag that selects the architecture/ISA to target. Unfortunately in cases where CONFIG_CPU_MIPS32_R{1,2}=y and the toolchain defaults to building for MIPS64, the main MIPS Makefile ends up using the short-form -<arch> flags in cflags-y. This is because the calls to cc-option always fail to use the long-form -march=<arch> flag due to the lack of an -mabi=<abi> flag in KBUILD_CFLAGS at the point where the cc-option function is executed. The resulting GCC invocation is something like: $ mips64-linux-gcc -Werror -march=mips32r2 -c -x c /dev/null -o tmp cc1: error: '-march=mips32r2' is not compatible with the selected ABI These short-form -<arch> flags are dropped by the VDSO Makefile's filtering, and so we attempt to build the VDSO without specifying any architecture. This results in an attempt to build the VDSO using whatever the compiler's default architecture is, regardless of whether that is suitable for the kernel configuration. One encountered build failure resulting from this mismatch is a rejection of the sync instruction if the kernel is configured for a MIPS32 or MIPS64 r1 or r2 target but the toolchain defaults to an older architecture revision such as MIPS1 which did not include the sync instruction: CC arch/mips/vdso/gettimeofday.o /tmp/ccGQKoOj.s: Assembler messages: /tmp/ccGQKoOj.s:273: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:329: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:520: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:714: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1009: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1066: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1114: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1279: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1334: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1374: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1459: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1514: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1814: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:2002: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:2066: Error: opcode not supported on this processor: mips1 (mips1) `sync' make[2]: *** [scripts/Makefile.build:318: arch/mips/vdso/gettimeofday.o] Error 1 make[1]: *** [scripts/Makefile.build:558: arch/mips/vdso] Error 2 make[1]: *** Waiting for unfinished jobs.... This can be reproduced for example by attempting to build pistachio_defconfig using Arnd's GCC 8.1.0 mips64 toolchain from kernel.org: https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/x86_64/8.1.0/… Resolve this problem by using the long-form -march=<arch> in all cases, which makes it through the arch/mips/vdso/Makefile's filtering & is thus consistently used to build both the kernel proper & the VDSO. The use of cc-option to prefer the long-form & fall back to the short-form flags makes no sense since the short-form is just an abbreviation for the also-supported long-form in all GCC versions that we support building with. This means there is no case in which we have to use the short-form -<arch> flags, so we can simply remove them. The manual redefinition of _MIPS_ISA is removed naturally along with the use of the short-form flags that it accompanied, and whilst here we remove the separate assembler ISA selection. I suspect that both of these were only required due to the mips32 vs mips2 mismatch that was introduced by commit 59b3e8e9aac6 ("[MIPS] Makefile crapectomy.") and fixed but not cleaned up by commit 9200c0b2a07c ("[MIPS] Fix Makefile bugs for MIPS32/MIPS64 R1 and R2."). I've marked this for backport as far as v4.4 where the MIPS VDSO was introduced. In earlier kernels there should be no ill effect to using the short-form flags.
