[v3 PATCH 0/5] powerpc/pseries: Machien check handler improvements.

by Mahesh J Salgaonkar

This patch series includes some improvement to Machine check handler for pseries. Patch 1 fixes an issue where machine check handler crashes kernel while accessing vmalloc-ed buffer while in nmi context. Patch 2 fixes endain bug while restoring of r3 in MCE handler. Patch 4 dumps the SLB contents on SLB MCE errors to improve the debugability. Patch 5 display's the MCE error details on console. CHange in V3: - Moved patch 5 to patch 2 Change in V2: - patch 3: Display additional info (NIP and task info) in MCE error details. - patch 5: Fix endain bug while restoring of r3 in MCE handler. --- Mahesh Salgaonkar (5): powerpc/pseries: convert rtas_log_buf to linear allocation. powerpc/pseries: Fix endainness while restoring of r3 in MCE handler. powerpc/pseries: Define MCE error event section. powerpc/pseries: Dump and flush SLB contents on SLB MCE errors. powerpc/pseries: Display machine check error details. arch/powerpc/include/asm/book3s/64/mmu-hash.h | 1 arch/powerpc/include/asm/rtas.h | 109 ++++++++++++++++++ arch/powerpc/kernel/rtasd.c | 2 arch/powerpc/mm/slb.c | 35 ++++++ arch/powerpc/platforms/pseries/ras.c | 155 +++++++++++++++++++++++++ 5 files changed, 299 insertions(+), 3 deletions(-) -- Signature

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

by Nathan Chancellor

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. 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 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

by Jason A. Donenfeld

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. It is planned to have it run on each of the containers mentioned above, using some container orchestration infrastructure.
