[PATCH 4.9] KVM: VMX: Expose SSBD properly to guests, 4.9 supplement

Fix an additional misuse of X86_FEATURE_SSBD in guest_cpuid_has_spec_ctrl().

[PATCH 4.4] brcmfmac: Fix check for ISO3166 code

by Ben Hutchings

From: Stefan Wahren <stefan.wahren(a)i2se.com> commit 9b9322db5c5a1917a66c71fe47c3848a9a31227e upstream. The commit "regulatory: add NUL to request alpha2" increases the length of alpha2 to 3. This causes a regression on brcmfmac, because brcmf_cfg80211_reg_notifier() expect valid ISO3166 codes in the complete array. So fix this accordingly.

[PATCH v11 0/7] dax: fix dma vs truncate/hole-punch

by Dan Williams

Changes since v9 [1] and v10 [2] * Resend the full series with the reworked "mm: introduce MEMORY_DEVICE_FS_DAX and CONFIG_DEV_PAGEMAP_OPS" (Christoph) * Move generic_dax_pagefree() into the pmem driver (Christoph) * Cleanup __bdev_dax_supported() (Christoph) * Cleanup some stale SRCU bits leftover from other iterations (Jan) * Cleanup xfs_break_layouts() (Jan) [1]: https://lists.01.org/pipermail/linux-nvdimm/2018-April/015457.html [2]: https://lists.01.org/pipermail/linux-nvdimm/2018-May/015885.html --- Background: get_user_pages() in the filesystem pins file backed memory pages for access by devices performing dma. However, it only pins the memory pages not the page-to-file offset association. If a file is truncated the pages are mapped out of the file and dma may continue indefinitely into a page that is owned by a device driver. This breaks coherency of the file vs dma, but the assumption is that if userspace wants the file-space truncated it does not matter what data is inbound from the device, it is not relevant anymore. The only expectation is that dma can safely continue while the filesystem reallocates the block(s). Problem: This expectation that dma can safely continue while the filesystem changes the block map is broken by dax. With dax the target dma page *is* the filesystem block. The model of leaving the page pinned for dma, but truncating the file block out of the file, means that the filesytem is free to reallocate a block under active dma to another file and now the expected data-incoherency situation has turned into active data-corruption. Solution: Defer all filesystem operations (fallocate(), truncate()) on a dax mode file while any page/block in the file is under active dma. This solution assumes that dma is transient. Cases where dma operations are known to not be transient, like RDMA, have been explicitly disabled via commits like 5f1d43de5416 "IB/core: disable memory registration of filesystem-dax vmas". The dax_layout_busy_page() routine is called by filesystems with a lock held against mm faults (i_mmap_lock) to find pinned / busy dax pages. The process of looking up a busy page invalidates all mappings to trigger any subsequent get_user_pages() to block on i_mmap_lock. The filesystem continues to call dax_layout_busy_page() until it finally returns no more active pages. This approach assumes that the page pinning is transient, if that assumption is violated the system would have likely hung from the uncompleted I/O. --- Dan Williams (7): memremap: split devm_memremap_pages() and memremap() infrastructure mm: introduce MEMORY_DEVICE_FS_DAX and CONFIG_DEV_PAGEMAP_OPS mm: fix __gup_device_huge vs unmap mm, fs, dax: handle layout changes to pinned dax mappings xfs: prepare xfs_break_layouts() to be called with XFS_MMAPLOCK_EXCL xfs: prepare xfs_break_layouts() for another layout type xfs, dax: introduce xfs_break_dax_layouts() drivers/dax/super.c | 14 ++- drivers/nvdimm/pfn_devs.c | 2 drivers/nvdimm/pmem.c | 25 +++++ fs/Kconfig | 1 fs/dax.c | 97 +++++++++++++++++++++ fs/xfs/xfs_file.c | 72 ++++++++++++++-- fs/xfs/xfs_inode.h | 16 +++ fs/xfs/xfs_ioctl.c | 8 -- fs/xfs/xfs_iops.c | 16 ++- fs/xfs/xfs_pnfs.c | 15 ++- fs/xfs/xfs_pnfs.h | 5 + include/linux/dax.h | 7 ++ include/linux/memremap.h | 36 ++------ include/linux/mm.h | 71 +++++++++++---- kernel/Makefile | 3 - kernel/iomem.c | 167 ++++++++++++++++++++++++++++++++++++ kernel/memremap.c | 209 ++++++--------------------------------------- mm/Kconfig | 5 + mm/gup.c | 36 ++++++-- mm/hmm.c | 13 --- mm/swap.c | 3 - 21 files changed, 542 insertions(+), 279 deletions(-) create mode 100644 kernel/iomem.c

Then I saw the following warning in dmesg. I saved it and rebooted immediately. memremap attempted on mixed range 0x000000000009c000 size: 0x1000 ------------[ cut here ]------------ WARNING: CPU: 0 PID: 11810 at kernel/memremap.c:98 memremap+0x104/0x170 [..] Call Trace: xlate_dev_mem_ptr+0x25/0x40 read_mem+0x89/0x1a0 __vfs_read+0x36/0x170 The memremap() implementation checks for attempts to remap System RAM with MEMREMAP_WB and instead redirects those mapping attempts to the linear map. However, that only works if the physical address range being remapped is page aligned.

Given that devmem_is_allowed() special cases any attempt to map System RAM in the first 1MB of memory, replace page_is_ram() with the more precise region_intersects() to trap attempts to map disallowed ranges.

[net 4/5] ixgbe: Avoid loopback and fix boolean logic in ipsec_stop_data

by Jeff Kirsher

From: Alexander Duyck <alexander.h.duyck(a)intel.com> This patch fixes two issues. First we add an early test for the Tx and Rx security block ready bits. By doing this we can avoid the need for waits or loopback in the event that the security block is already flushed out. Secondly we fix the boolean logic that was testing for the Tx OR Rx ready bits being set and change it so that we only exit if the Tx AND Rx ready bits are both set.

This way it is a bit more consistent with the placement of similar initialization functions and is placed before the reset_hw call which should allow us to clean up any link issues that may be introduced by the fact that we force the link up if somehow the device had IPsec still enabled before the driver was loaded. In addition to the function move it is necessary to change the assignment of netdev->features. The easiest way to do this is to just test for the existence of adapter->ipsec and if it is present we set the feature bits.

[net 1/5] ixgbe: Fix setting of TC configuration for macvlan case

by Jeff Kirsher

From: Alexander Duyck <alexander.h.duyck(a)intel.com> When we were enabling macvlan interfaces we weren't correctly configuring things until ixgbe_setup_tc was called a second time either by tweaking the number of queues or increasing the macvlan count past 15. The issue came down to the fact that num_rx_pools is not populated until after the queues and interrupts are reinitialized. Instead of trying to set it sooner we can just move the call to setup at least 1 traffic class to the SR-IOV/VMDq setup function so that we just set it for this one case. We already had a spot that was configuring the queues for TC 0 in the code here anyway so it makes sense to also set the number of TCs here as well.

[PATCH] mm: Fix devmem_is_allowed() for sub-page System RAM intersections

by Dan Williams

Hussam reports: I was poking around and for no real reason, I did cat /dev/mem and strings /dev/mem. Then I saw the following warning in dmesg. I saved it and rebooted immediately. memremap attempted on mixed range 0x000000000009c000 size: 0x1000 ------------[ cut here ]------------ WARNING: CPU: 0 PID: 11810 at kernel/memremap.c:98 memremap+0x104/0x170 [..] Call Trace: xlate_dev_mem_ptr+0x25/0x40 read_mem+0x89/0x1a0 __vfs_read+0x36/0x170 The memremap() implementation checks for attempts to remap System RAM with MEMREMAP_WB and instead redirects those mapping attempts to the linear map. However, that only works if the physical address range being remapped is page aligned. In low memory we have situations like the following: 00000000-00000fff : Reserved 00001000-0009fbff : System RAM 0009fc00-0009ffff : Reserved ...where System RAM intersects Reserved ranges on a sub-page page granularity. Given that devmem_is_allowed() special cases any attempt to map System RAM in the first 1MB of memory, replace page_is_ram() with the more precise region_intersects() to trap attempts to map disallowed ranges.

[merged] mm-page_alloc-do-not-break-__gfp_thisnode-by-zonelist-reset.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm, page_alloc: do not break __GFP_THISNODE by zonelist reset has been removed from the -mm tree. Its filename was mm-page_alloc-do-not-break-__gfp_thisnode-by-zonelist-reset.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Vlastimil Babka <vbabka(a)suse.cz> Subject: mm, page_alloc: do not break __GFP_THISNODE by zonelist reset In __alloc_pages_slowpath() we reset zonelist and preferred_zoneref for allocations that can ignore memory policies. The zonelist is obtained from current CPU's node. This is a problem for __GFP_THISNODE allocations that want to allocate on a different node, e.g. because the allocating thread has been migrated to a different CPU. This has been observed to break SLAB in our 4.4-based kernel, because there it relies on __GFP_THISNODE working as intended. If a slab page is put on wrong node's list, then further list manipulations may corrupt the list because page_to_nid() is used to determine which node's list_lock should be locked and thus we may take a wrong lock and race. Current SLAB implementation seems to be immune by luck thanks to commit 511e3a058812 ("mm/slab: make cache_grow() handle the page allocated on arbitrary node") but there may be others assuming that __GFP_THISNODE works as promised. We can fix it by simply removing the zonelist reset completely. There is actually no reason to reset it, because memory policies and cpusets don't affect the zonelist choice in the first place. This was different when commit 183f6371aac2 ("mm: ignore mempolicies when using ALLOC_NO_WATERMARK") introduced the code, as mempolicies provided their own restricted zonelists. We might consider this for 4.17 although I don't know if there's anything currently broken. SLAB is currently not affected, but in kernels older than 4.7 that don't yet have 511e3a058812 ("mm/slab: make cache_grow() handle the page allocated on arbitrary node") it is. That's at least 4.4 LTS. Older ones I'll have to check. So stable backports should be more important, but will have to be reviewed carefully, as the code went through many changes. BTW I think that also the ac->preferred_zoneref reset is currently useless if we don't also reset ac->nodemask from a mempolicy to NULL first (which we probably should for the OOM victims etc?), but I would leave that for a separate patch.

[PATCH] arm64: Fix syscall restarting around signal suppressed by tracer

by Dave Martin

Commit 17c2895 ("arm64: Abstract syscallno manipulation") abstracts out the pt_regs.syscallno value for a syscall cancelled by a tracer as NO_SYSCALL, and provides helpers to set and check for this condition. However, the way this was implemented has the unintended side-effect of disabling part of the syscall restart logic. This comes about because the second in_syscall() check in do_signal() re-evaluates the "in a syscall" condition based on the updated pt_regs instead of the original pt_regs. forget_syscall() is explicitly called prior to the second check in order to prevent restart logic in the ret_to_user path being spuriously triggered, which means that the second in_syscall() check always yields false. This triggers a failure in tools/testing/selftests/seccomp/seccomp_bpf.c, when using ptrace to suppress a signal that interrups a nanosleep() syscall. Misbehaviour of this type is only expected in the case where a tracer suppresses a signal and the target process is either being single-stepped or the interrupted syscall attempts to restart via -ERESTARTBLOCK. This patch restores the old behaviour by performing the in_syscall() check only once at the start of the function.

[PATCH] dm bufio: avoid false-positive Wmaybe-uninitialized warning

From: Arnd Bergmann <arnd(a)arndb.de> commit 590347e4000356f55eb10b03ced2686bd74dab40 upstream. gcc-6.3 and earlier show a new warning after a seemingly unrelated change to the arm64 PAGE_KERNEL definition: In file included from drivers/md/dm-bufio.c:14:0: drivers/md/dm-bufio.c: In function 'alloc_buffer': include/linux/sched/mm.h:182:56: warning: 'noio_flag' may be used uninitialized in this function [-Wmaybe-uninitialized] current->flags = (current->flags & ~PF_MEMALLOC_NOIO) | flags; ^ The same warning happened earlier on linux-3.18 for MIPS and I did a workaround for that, but now it's come back. gcc-7 and newer are apparently smart enough to figure this out, and other architectures don't show it, so the best I could come up with is to rework the caller slightly in a way that makes it obvious enough to all arm64 compilers what is happening here.

[patch 079/118] mm, page_alloc: do not break __GFP_THISNODE by zonelist reset

by akpm＠linux-foundation.org

From: Vlastimil Babka <vbabka(a)suse.cz> Subject: mm, page_alloc: do not break __GFP_THISNODE by zonelist reset In __alloc_pages_slowpath() we reset zonelist and preferred_zoneref for allocations that can ignore memory policies. The zonelist is obtained from current CPU's node. This is a problem for __GFP_THISNODE allocations that want to allocate on a different node, e.g. because the allocating thread has been migrated to a different CPU. This has been observed to break SLAB in our 4.4-based kernel, because there it relies on __GFP_THISNODE working as intended. If a slab page is put on wrong node's list, then further list manipulations may corrupt the list because page_to_nid() is used to determine which node's list_lock should be locked and thus we may take a wrong lock and race. Current SLAB implementation seems to be immune by luck thanks to commit 511e3a058812 ("mm/slab: make cache_grow() handle the page allocated on arbitrary node") but there may be others assuming that __GFP_THISNODE works as promised. We can fix it by simply removing the zonelist reset completely. There is actually no reason to reset it, because memory policies and cpusets don't affect the zonelist choice in the first place. This was different when commit 183f6371aac2 ("mm: ignore mempolicies when using ALLOC_NO_WATERMARK") introduced the code, as mempolicies provided their own restricted zonelists. We might consider this for 4.17 although I don't know if there's anything currently broken. SLAB is currently not affected, but in kernels older than 4.7 that don't yet have 511e3a058812 ("mm/slab: make cache_grow() handle the page allocated on arbitrary node") it is.

[patch 079/118] mm, page_alloc: do not break __GFP_THISNODE by zonelist reset

by akpm＠linux-foundation.org

From: Vlastimil Babka <vbabka(a)suse.cz> Subject: mm, page_alloc: do not break __GFP_THISNODE by zonelist reset In __alloc_pages_slowpath() we reset zonelist and preferred_zoneref for allocations that can ignore memory policies. The zonelist is obtained from current CPU's node. This is a problem for __GFP_THISNODE allocations that want to allocate on a different node, e.g. because the allocating thread has been migrated to a different CPU. This has been observed to break SLAB in our 4.4-based kernel, because there it relies on __GFP_THISNODE working as intended. If a slab page is put on wrong node's list, then further list manipulations may corrupt the list because page_to_nid() is used to determine which node's list_lock should be locked and thus we may take a wrong lock and race. Current SLAB implementation seems to be immune by luck thanks to commit 511e3a058812 ("mm/slab: make cache_grow() handle the page allocated on arbitrary node") but there may be others assuming that __GFP_THISNODE works as promised. We can fix it by simply removing the zonelist reset completely. There is actually no reason to reset it, because memory policies and cpusets don't affect the zonelist choice in the first place. This was different when commit 183f6371aac2 ("mm: ignore mempolicies when using ALLOC_NO_WATERMARK") introduced the code, as mempolicies provided their own restricted zonelists. We might consider this for 4.17 although I don't know if there's anything currently broken. SLAB is currently not affected, but in kernels older than 4.7 that don't yet have 511e3a058812 ("mm/slab: make cache_grow() handle the page allocated on arbitrary node") it is. That's at least 4.4 LTS. Older ones I'll have to check. So stable backports should be more important, but will have to be reviewed carefully, as the code went through many changes. BTW I think that also the ac->preferred_zoneref reset is currently useless if we don't also reset ac->nodemask from a mempolicy to NULL first (which we probably should for the OOM victims etc?), but I would leave that for a separate patch.

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

by Dan Williams

Mark notes that gcc optimization passes have the potential to elide necessary invocations of this instruction sequence, so include an optimization barrier. > I think that either way, we have a potential problem if the compiler > generates a branch dependent on the result of validate_index_nospec(). > > In that case, we could end up with codegen approximating: > > bool safe = false; > > if (idx < bound) { > idx = array_index_nospec(idx, bound); > safe = true; > } > > // this branch can be mispredicted > if (safe) { > foo = array[idx]; > } > > ... and thus we lose the nospec protection. I see GCC do this at -O0, but so far I haven't tricked it into doing this at -O1 or above. Regardless, I worry this is fragile -- GCC *can* generate code as per the above, even if it's unlikely to.

[PATCH 4.16.y] netfilter: nf_flow_table: attach dst to skbs

commit 2a79fd3908acd88e6cb0e620c314d7b1fee56a02 upstream. Some drivers, such as vxlan and wireguard, use the skb's dst in order to determine things like PMTU.

Please add e2731e55884f2138a252b0a to 4.14 and 4.9

by David Sterba

Hi, please add the commit e2731e55884f2138a252b0a3d7b24d57e49c3c59 ("btrfs: define SUPER_FLAG_METADUMP_V2") to the 4.14.x and 4.9.x stable trees. The patch allows to mount an image dump of v2 format on < 4.15 kernels that are still in use for the btrfs-progs testsuite. The image mount is part of some tests that fail but otherwise are ok. The patch can be cleanly applied on top of current 4.14 and 4.9 branches, fails on 4.4 and older but I'm interested namely in 4.14. Thanks.

[GIT PULL 00/46] perf/core fixes and improvements

by Arnaldo Carvalho de Melo

From: Arnaldo Carvalho de Melo <acme(a)redhat.com> Hi Ingo, Please consider pulling, - Arnaldo Test results at the end of this message, as usual. The following changes since commit 7869e5889477e4e32e4024d665431b35e8b7b693: Merge remote-tracking branch 'tip/perf/urgent' into perf/core (2018-06-04 10:28:20 -0300) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git tags/perf-core-for-mingo-4.18-20180605 for you to fetch changes up to 03ac4e71cd120d2c3411d106d00d266114575f74: perf intel-pt: Fix "Unexpected indirect branch" error (2018-06-05 12:28:52 -0300) ---------------------------------------------------------------- perf/core improvements and fixes: perf stat: . Display user and system time for workload targets (Jiri Olsa) perf record: . Enable arbitrary event names thru name= modifier (Alexey Budankov) PowerPC: . Add a python script for hypervisor call statistics (Ravi Bangoria) Intel PT: (Adrian Hunter) . Fix sync_switch INTEL_PT_SS_NOT_TRACING . Fix decoding to accept CBR between FUP and corresponding TIP . Fix MTC timing after overflow . Fix "Unexpected indirect branch" error perf test: . record+probe_libc_inet_pton: . To get the symbol table for dynamic shared objects on ubuntu we need to pass the -D/--dynamic command line option, unlike with the fedora distros (Arnaldo Carvalho de Melo) . code-reading: . Fix perf_env setup for PTI entry trampolines (Adrian Hunter) . kmod-path: . Add tests for vdso32 and vdsox32 (Adrian Hunter) . Use header file util/debug.h (Thomas Richter) perf annotate: . Make the various UI backends (stdio, TUI, gtk) use more consistently structs with annotation options as specified by the user (Arnaldo Carvalho de Melo) . Move annotation specific knobs from the symbol_conf global kitchen sink to the annotation option structs (Arnaldo Carvalho de Melo) Core: . Fix misleading error for some unparsable events mentioning PMUs when those are not involved in the problem (Jiri Olsa) - Fix symbol and object code resolution for vdso32 and vdsox32 (Adrian Hunter) . No need to check for null when passing pointers to foo__get() style refcount grabbing helpers, just like in the kernel and with free(), its safe to pass a NULL pointer to avoid having to check it before each and every foo__get() call (Arnaldo Carvalho de Melo) . Remove some dead code (quote.[ch]) (Arnaldo Carvalho de Melo) . Remove some needless globals, making them local (Arnaldo Carvalho de Melo) . Reduce usage of symbol_conf.use_callchain, using other means of finding out if callchains are in use or available for specific events, as we evolved this codebase to allow requesting callchains for just a subset of the monitored events. In time it will help polish recording and showing mixed sets accross the various tools: perf record -e cycles/call-graph=fp/,cache-misses/call-graph=dwarf/,instructions (Arnaldo Carvalho de Melo) . Consider PTI entry trampolines in map__rip_2objdump() (Adrian Hunter) Signed-off-by: Arnaldo Carvalho de Melo <acme(a)redhat.com> ---------------------------------------------------------------- Adrian Hunter (8): perf tests kmod-path: Add tests for vdso32 and vdsox32 perf tools: Fix symbol and object code resolution for vdso32 and vdsox32 perf test code-reading: Fix perf_env setup for PTI entry trampolines perf map: Consider PTI entry trampolines in rip_2objdump() perf intel-pt: Fix sync_switch INTEL_PT_SS_NOT_TRACING perf intel-pt: Fix decoding to accept CBR between FUP and corresponding TIP perf intel-pt: Fix MTC timing after overflow perf intel-pt: Fix "Unexpected indirect branch" error Alexey Budankov (1): perf record: Enable arbitrary event names thru name= modifier Arnaldo Carvalho de Melo (33): perf tools: Remove dead quote.[ch] code perf probe: Use return of map__get() to make code more compact perf cgroup: Make evlist__find_cgroup() more compact perf tools: No need to check if the argument to __get() function is NULL perf annotate: Pass perf_evsel instead of just evsel->idx perf annotate: __symbol__acount_cycles doesn't need notes perf annotate: Split allocation of annotated_source struct perf annotate: Introduce constructor/destructor for annotated_source perf annotate: Introduce annotated_source__alloc_histograms perf annotate: __symbol__inc_addr_samples() needs just annotated_source perf annotate: Introduce symbol__hists() perf annotate: Introduce symbol__cycle_hists() perf annotate: Stop using symbol_conf.nr_events global in symbol__hists() perf annotate: Replace symbol__alloc_hists() with symbol__hists() perf tools: Ditch the symbol_conf.nr_events global perf annotate: Add comment about annotated_src->nr_histograms perf annotate stdio: Use annotation_options consistently perf srcline: Introduce map__srcline() to make code more compact perf sort: Introduce addr_map_symbol__srcline() to make code more compact perf srcline: Make hist_entry srcline helper consistent with map's perf annotate: Pass annotation_options to symbol__annotate() perf annotate: Adopt anotation options from symbol_conf perf annotate: Move disassembler_style global to annotation_options perf hists browser: Pass annotation_options from tool to browser perf annotate: Move objdump_path to struct annotation_options perf report: No need to have report_callchain_help as a global perf evsel: Add has_callchain() helper to make code more compact/clear perf script: Check if evsel has callchains before trying to use it perf sched: Use sched->show_callchain where appropriate perf hists: Do not allocate space for callchains for evsels without them perf hists: Introduce hist_entry__has_callchain() method perf hists: Check if a hist_entry has callchains before using them perf test record+probe_libc_inet_pton: Ask 'nm' for dynamic symbols Jiri Olsa (2): perf stat: Display user and system time perf tools: Fix pmu events parsing rule Ravi Bangoria (1): perf script powerpc: Python script for hypervisor call statistics Thomas Richter (1): perf test: Use header file util/debug.h tools/perf/Documentation/perf-list.txt | 6 +- tools/perf/Documentation/perf-record.txt | 3 + tools/perf/Documentation/perf-stat.txt | 40 +++-- tools/perf/arch/common.c | 4 +- tools/perf/arch/common.h | 4 +- tools/perf/builtin-annotate.c | 36 ++-- tools/perf/builtin-c2c.c | 2 +- tools/perf/builtin-kvm.c | 2 -

Where clang is available, it is also used to build perf with/without libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang when clang and its devel libraries are installed. The objtool and samples/bpf/ builds are disabled now that I'm switching from using the sources in a local volume to fetching them from a http server to build it inside the container, to make it easier to build in a container cluster. Those will come back later. Several are cross builds, the ones with -x-ARCH and the android one, and those may not have all the features built, due to lack of multi-arch devel packages, available and being used so far on just a few, like debian:experimental-x-{arm64,mipsel}. The 'perf test' one will perform a variety of tests exercising tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands with a variety of command line event specifications to then intercept the sys_perf_event syscall to check that the perf_event_attr fields are set up as expected, among a variety of other unit tests. Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/ with a variety of feature sets, exercising the build with an incomplete set of features as well as with a complete one.

[char-misc 2/2] mei: discard messages from not connected client during power down.

by Tomas Winkler

From: Alexander Usyskin <alexander.usyskin(a)intel.com> This fixes regression introduced by commit 8d52af6795c0 ("mei: speed up the power down flow") In power down or suspend flow a message can still be received from the FW because the clients fake disconnection. In normal case we interpret messages w/o destination as corrupted and link reset is performed in order to clean the channel, but during power down link reset is already in progress resulting in endless loop. To resolve the issue under power down flow we discard messages silently.

[PATCH] ARC: Remove CONFIG_INITRAMFS_SOURCE from defconfigs

by Alexey Brodkin

We used to have pre-set CONFIG_INITRAMFS_SOURCE with local path to intramfs in ARC defconfigs. This was quite convenient for in-house development but not that convenient for newcomers who obviusly don't have folders like "arc_initramfs" next to the Linux source tree. Which leads to quite surprising failure of defconfig building: ------------------------------->8----------------------------- ../scripts/gen_initramfs_list.sh: Cannot open '../../arc_initramfs_hs/' ../usr/Makefile:57: recipe for target 'usr/initramfs_data.cpio.gz' failed make[2]: *** [usr/initramfs_data.cpio.gz] Error 1 ------------------------------->8----------------------------- So now when more and more people start to deal with our defconfigs let's make their life easier with removal of CONFIG_INITRAMFS_SOURCE.

[PATCH v13 1/3] ioremap: Update pgtable free interfaces with addr

by Chintan Pandya

From: Chintan Pandya <cpandya(a)codeaurora.org> The following kernel panic was observed on ARM64 platform due to a stale TLB entry. 1. ioremap with 4K size, a valid pte page table is set. 2. iounmap it, its pte entry is set to 0. 3. ioremap the same address with 2M size, update its pmd entry with a new value. 4. CPU may hit an exception because the old pmd entry is still in TLB, which leads to a kernel panic. Commit b6bdb7517c3d ("mm/vmalloc: add interfaces to free unmapped page table") has addressed this panic by falling to pte mappings in the above case on ARM64. To support pmd mappings in all cases, TLB purge needs to be performed in this case on ARM64.

[PATCH 1/9] dm-integrity: change the variable suspending from bool to int

by Mikulas Patocka

The early alpha processors can't write a byte or short atomically - they read 8 bytes, modify the byte or two bytes in registers and write back 8 bytes. The modification of the variable "suspending" may race with modification of the variable "failed". This patch changes suspending to an int.

netfilter: nf_flow_table: attach dst to skbs

by Jason A. Donenfeld

Some drivers, such as vxlan and wireguard, use the skb's dst in order to determine things like PMTU. They therefore loose functionality when flow offloading is enabled. So, we ensure the skb has it before xmit'ing it in the offloading path. Signed-off-by: Jason A.

[PATCH v2 1/2] pwm: lpss: platform: Save/restore the ctrl register over a suspend/resume

by Hans de Goede

On some devices the contents of the ctrl register get lost over a suspend/resume and the PWM comes back up disabled after the resume. This is seen on some Bay Trail devices with the PWM in ACPI enumerated mode, so it shows up as a platform device instead of a PCI device. If we still think it is enabled and then try to change the duty-cycle after this, we end up with a "PWM_SW_UPDATE was not cleared" error and the PWM is stuck in that state from then on. This commit adds suspend and resume pm callbacks to the pwm-lpss-platform code, which save/restore the ctrl register over a suspend/resume, fixing this. Note that: 1) There is no need to do this over a runtime suspend, since we only runtime suspend when disabled and then we properly set the enable bit and reprogram the timings when we re-enable the PWM. 2) This may be happening on more systems then we realize, but has been covered up sofar by a bug in the acpi-lpss.c code which was save/restoring the regular device registers instead of the lpss private registers due to lpss_device_desc.prv_offset not being set. This is fixed by a later patch in this series.

Problems building ppc images in v4.14.y and v4.16.y using gcc 7.3.0 / 8.1.0 from kernel.org

by Guenter Roeck

Hi Arnd, when using the ppc64 compiler from kernel.org, I see the following problems when trying to compile ppc:allnoconfig in v4.14.y or v4.16.y. gcc 7.3.0: Compilation of kernel.cpu.o hangs The problem goes away if I apply the following two patches (tested with 4.16.y) 17a2f1ced028 cpu/hotplug: Merge cpuhp_bp_states and cpuhp_ap_states fcb3029a8d89 cpu/hotplug: Fix unused function warning gcc 8.1.0: Compilation of kernel/cpu.o results in the following error powerpc64-linux-gcc: error: unrecognized command line option '-mno-spe'; did you mean '-fno-see'? powerpc64-linux-gcc: error: unrecognized command line option '-mspe=no'; did you mean '-misel=no'? This problem is also seen with mainline. With ppc:defconfig, kernel/cpu.o builds fine with both compiler versions. Have you seen similar problems ? Any idea what to do about it, other than sticking with older compilers ? Thanks, Guenter

[PATCH 1/2] btrfs: scrub: Don't use inode pages for device replace

by Qu Wenruo

[BUG] Btrfs can easily create compressed extent without checksum (even though it shouldn't), and if we then try to replace device containing such extent, the result device will contain all the uncompressed data instead of the compressed one. Test case already submitted to fstests: https://patchwork.kernel.org/patch/10442353/ [CAUSE] When handling compressed extent without checksum, device replace will goes into copy_nocow_pages() function. In that function, btrfs will get all inodes referring to this data extents and then use find_or_create_page() to get pages direct from that inode. The problem here is, pages directly from inode are always uncompressed. And for compressed data extent, they mismatch with on-disk data. Thus this leads to corrupted data extent written to replace device. [FIX] In this patch, we could just avoid the "optimization" branch, and let unified scrub_pages() to handle it. Although scrub_pages() won't bother reusing page cache, thus it will be a little slower, but it does the correct csum checking (skipped in this case) and won't cause such data corruption cause by "optimization". Please note that, this patch will just avoid the copy_nocow_pages(), while still leave related functions here, to make it small enough for a late merge window. Full functions removal will happen later.

[PATCH V5] scsi: hpsa: disable device during shutdown

by Sinan Kaya

'Commit cc27b735ad3a ("PCI/portdrv: Turn off PCIe services during shutdown")' has been added to kernel to shutdown pending PCIe port service interrupts during reboot so that a newly started kexec kernel wouldn't observe pending interrupts. pcie_port_device_remove() is disabling the root port and switches by calling pci_disable_device() after all PCIe service drivers are shutdown. This has been found to cause crashes on HP DL360 Gen9 machines during reboot due to hpsa driver not clearing the bus master bit during the shutdown procedure by calling pci_disable_device(). Disable device as part of the shutdown sequence.

[PATCH v3 2/2] tpm: self test failure should not cause suspend to fail

by Jarkko Sakkinen

From: Chris Chiu <chiu(a)endlessm.com> commit 0803d7befa15cab5717d667a97a66214d2a4c083 upstream The Acer Acer Veriton X4110G has a TPM device detected as: tpm_tis 00:0b: 1.2 TPM (device-id 0xFE, rev-id 71) After the first S3 suspend, the following error appears during resume: tpm tpm0: A TPM error(38) occurred continue selftest Any following S3 suspend attempts will now fail with this error: tpm tpm0: Error (38) sending savestate before suspend PM: Device 00:0b failed to suspend: error 38 Error 38 is TPM_ERR_INVALID_POSTINIT which means the TPM is not in the correct state. This indicates that the platform BIOS is not sending the usual TPM_Startup command during S3 resume. >From this point onwards, all TPM commands will fail. The same issue was previously reported on Foxconn 6150BK8MC and Sony Vaio TX3. The platform behaviour seems broken here, but we should not break suspend/resume because of this. When the unexpected TPM state is encountered, set a flag to skip the affected TPM_SaveState command on later suspends.

[git:media_tree/master] media: uvcvideo: Prevent setting unavailable flags

This is an automatic generated email to let you know that the following patch were queued: Subject: media: uvcvideo: Prevent setting unavailable flags Author: Kieran Bingham <kieran.bingham(a)ideasonboard.com> Date: Wed Mar 21 11:43:08 2018 -0400 The addition of an extra operation to use the GET_INFO command overwrites all existing flags from the uvc_ctrls table. This includes setting all controls as supporting GET_MIN, GET_MAX, GET_RES, and GET_DEF regardless of whether they do or not. Move the initialisation of these control capabilities directly to the uvc_ctrl_fill_xu_info() call where they were originally located in that use case, and ensure that the new functionality in uvc_ctrl_get_flags() will only set flags based on their reported capability from the GET_INFO call.

[PATCH v4.9-stable] serial: pl011: add console matching function

by Ard Biesheuvel

From: Aleksey Makarov <aleksey.makarov(a)linaro.org> Commit 10879ae5f12e9cab3c4e8e9504c1aaa8a033bde7 upstream. This patch adds function pl011_console_match() that implements method match of struct console. It allows to match consoles against data specified in a string, for example taken from command line or compiled by ACPI SPCR table handler. This patch was merged to tty-next but then reverted because of conflict with commit 46e36683f433 ("serial: earlycon: Extend earlycon command line option to support 64-bit addresses") Now it is fixed. Signed-off-by: Aleksey Makarov <aleksey.makarov(a)linaro.org> Reviewed-by: Peter Hurley <peter(a)hurleysoftware.com> Acked-by: Russell King <rmk+kernel(a)armlinux.org.uk> Tested-by: Christopher Covington <cov(a)codeaurora.org> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Signed-off-by: Ard Biesheuvel <ard.biesheuvel(a)linaro.org> --- Please consider for v4.9-stable. It is the missing puzzle piece for SPCR support on arm64 ACPI systems, which got merged for v4.9 [0]. Now that more systems are becoming available to people working in the kernel community, it turns out that v4.9 distro installers (e.g., Debian Stretch) won't work unless you pass a 'console=' parameter explicitly, which is annoying. Given that it was clearly the intent to include this code at the time, I hope it will be considered for backporting. [0] To quote the tty maintainer: Also in here is the long-suffering ACPI SPCR patchset, which was passed around from maintainer to maintainer like a hot-potato. Seems I was the sucker^Wlucky one.

[PATCH v2 0/2] 4.14 long term stable ZBC fixes

by Damien Le Moal

Patch 4b433924b275 ("scsi: sd_zbc: Fix potential memory leak") was added in 4.16 and 4.15 stable but did not make it to long term stable 4.14 (as far as I can tell). Patch ccce20fc7968 ("scsi: sd_zbc: Avoid that resetting a zone fails sporadically") is included in 4.16 but does not apply to 4.15 stable nor to 4.14 long term stable and requires extensive modifications. This small series provides a backport of both patches against 4.14. Please consider these patches for inclusion in this long term stable kernel.

[merged] mm-huge_memoryc-__split_huge_page-use-atomic-clearpagedirty.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm/huge_memory.c: __split_huge_page() use atomic ClearPageDirty() has been removed from the -mm tree. Its filename was mm-huge_memoryc-__split_huge_page-use-atomic-clearpagedirty.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Hugh Dickins <hughd(a)google.com> Subject: mm/huge_memory.c: __split_huge_page() use atomic ClearPageDirty() Swapping load on huge=always tmpfs (with khugepaged tuned up to be very eager, but I'm not sure that is relevant) soon hung uninterruptibly, waiting for page lock in shmem_getpage_gfp()'s find_lock_entry(), most often when "cp -a" was trying to write to a smallish file. Debug showed that the page in question was not locked, and page->mapping NULL by now, but page->index consistent with having been in a huge page before. Reproduced in minutes on a 4.15 kernel, even with 4.17's 605ca5ede764 ("mm/huge_memory.c: reorder operations in __split_huge_page_tail()") added in; but took hours to reproduce on a 4.17 kernel (no idea why). The culprit proved to be the __ClearPageDirty() on tails beyond i_size in __split_huge_page(): the non-atomic __bitoperation may have been safe when 4.8's baa355fd3314 ("thp: file pages support for split_huge_page()") introduced it, but liable to erase PageWaiters after 4.10's 62906027091f ("mm: add PageWaiters indicating tasks are waiting for a page bit").

[PATCH v2] rpmsg: smd: do not use mananged resources for endpoints and channels

by Srinivas Kandagatla

All the managed resources would be freed by the time release function is invoked. Handling such memory in qcom_smd_edge_release() would do bad things. Found this issue while testing Audio usecase where the dsp is started up and shutdown in a loop. This patch fixes this issue by using simple kzalloc for allocating channel->name and channel which is then freed in qcom_smd_edge_release(). Without this patch restarting a remoteproc would crash the system.
