tools: Synchronize tools/include/uapi/linux/bpf.h

2016-10-05T22:31:48Z

Commit 747ea55e4f78 ("bpf: fix bpf_skb_in_cgroup helper naming") renames BPF_FUNC_skb_in_cgroup to bpf_skb_under_cgroup, triggering this warning while building perf: Warning: tools/include/uapi/linux/bpf.h differs from kernel Update the copy to ack that, no changes needed, as BPF_FUNC_skb_in_cgroup isn't used so far.

tools include: Add uapi mman.h for each architecture

2016-09-13T18:26:08Z

Some mmap related macros have different values for different architectures. This patch introduces uapi mman.h for each architectures. Three headers are cloned from kernel include to tools/include: tools/include/uapi/asm-generic/mman-common.h tools/include/uapi/asm-generic/mman.h tools/include/uapi/linux/mman.h The main part of this patch is generated by following script: macros=`cat $0 | awk 'V==1 {print}; /^# start macro list/ {V=1}'` for arch in `ls tools/arch` do [ -d tools/arch/$arch/include/uapi/asm ] || mkdir -p tools/arch/$arch/include/uapi/asm src=arch/$arch/include/uapi/asm/mman.h target=tools/arch/$arch/include/uapi/asm/mman.h guard="TOOLS_ARCH_"`echo $arch | awk '{print toupper($0)}'`_UAPI_ASM_MMAN_FIX_H echo '#ifndef '$guard > $target echo '#define '$guard >> $target [ -f $src ] && for m in $macros do if grep '#define[ \t]*'$m $src > /dev/null 2>&1 then grep -h '#define[ \t]*'$m $src | sed 's/[ \t]*\/\*.*$//g' >> $target fi done if [ -f $src ] then grep '#include > $target else echo "#include " >> $target fi echo '#endif' >> $target echo "$target" done exit 0 # Following macros are extracted from: # tools/perf/trace/beauty/mmap.c # # start macro list MADV_DODUMP MADV_DOFORK MADV_DONTDUMP MADV_DONTFORK MADV_DONTNEED MADV_HUGEPAGE MADV_HWPOISON MADV_MERGEABLE MADV_NOHUGEPAGE MADV_NORMAL MADV_RANDOM MADV_REMOVE MADV_SEQUENTIAL MADV_SOFT_OFFLINE MADV_UNMERGEABLE MADV_WILLNEED MAP_32BIT MAP_ANONYMOUS MAP_DENYWRITE MAP_EXECUTABLE MAP_FILE MAP_FIXED MAP_GROWSDOWN MAP_HUGETLB MAP_LOCKED MAP_NONBLOCK MAP_NORESERVE MAP_POPULATE MAP_PRIVATE MAP_SHARED MAP_STACK MAP_UNINITIALIZED MREMAP_FIXED MREMAP_MAYMOVE PROT_EXEC PROT_GROWSDOWN PROT_GROWSUP PROT_NONE PROT_READ PROT_SEM PROT_WRITE Signed-off-by: Wang Nan Cc: Zefan Li Cc: pi3orama@163.com Link: http://lkml.kernel.org/r/1473684871-209320-2-git-send-email-wangnan0@huawei.com [ Added new files to tools/perf/MANIFEST to fix the detached tarball build, add mman.h for ARC ] Signed-off-by: Arnaldo Carvalho de Melo

tools: Copy coresight-pmu.h header file needed by perf tools

2016-08-23T18:37:33Z

Directly accessing kernel files is not allowed anymore. As such making file coresight-pmu.h accessible by the perf tools and complain if this copy strays from the one found in the main kernel tree.

tools: Introduce tools/include/linux/time64.h for SEC_PER_SEC macros

2016-08-23T18:37:33Z

And remove it from tools/perf/{perf,util}.h, making code that needs these macros to include linux/time64.h instead, to match how this is used in the kernel sources.

tools lib: Reinstate strlcpy() header guard with UCLIBC

2016-08-18T19:19:13Z

perf tools build in recent kernels spews splat when cross compiling with uClibc: | CC util/alias.o | In file included from tools/perf/util/../ui/../util/cache.h:8:0, | from tools/perf/util/../ui/helpline.h:7, | from tools/perf/util/debug.h:8, | from arch/../util/cpumap.h:9, | from arch/../util/env.h:5, | from arch/common.h:4, | from arch/common.c:3: | tools/include/linux/string.h:12:15: warning: redundant redeclaration of ‘strlcpy’ [-Wredundant-decls] | extern size_t strlcpy(char *dest, const char *src, size_t size); ^ This is after commit 61a6445e463a31 ("tools lib: Guard the strlcpy() header with __GLIBC__"). The problem is uClibc also defines __GLIBC__ for exported headers for applications. So add that specific check to not trip for uClibc.

toops: Sync tools/include/uapi/linux/bpf.h with the kernel

2016-08-09T14:48:07Z

The way we're using kernel headers in tools/ now, with a copy that is made to the same path prefixed by "tools/" plus checking if that copy got stale, i.e. if the kernel counterpart changed, helps in keeping track with new features that may be useful for tools to exploit. For instance, looking at all the changes to bpf.h since it was last copied to tools/include brings this to toolers' attention: Need to investigate this one to check how to run a program via perf, setting up a BPF event, that will take advantage of the way perf already calls clang/LLVM, sets up the event and runs the workload in a single command line, helping in debugging such semi cooperative programs: 96ae52279594 ("bpf: Add bpf_probe_write_user BPF helper to be called in tracers") This one needs further investigation about using the feature it improves in 'perf trace' to do some tcpdumpin' mixed with syscalls, tracepoints, probe points, callgraphs, etc: 555c8a8623a3 ("bpf: avoid stack copy and use skb ctx for event output") Add tracing just packets that are related to some container to that mix: 4a482f34afcc ("cgroup: bpf: Add bpf_skb_in_cgroup_proto") 4ed8ec521ed5 ("cgroup: bpf: Add BPF_MAP_TYPE_CGROUP_ARRAY") Definetely needs to have example programs accessing task_struct from a bpf proggie started from 'perf trace': 606274c5abd8 ("bpf: introduce bpf_get_current_task() helper") Core networking related, XDP: 6ce96ca348a9 ("bpf: add XDP_TX xdp_action for direct forwarding") 6a773a15a1e8 ("bpf: add XDP prog type for early driver filter") 13c5c240f789 ("bpf: add bpf_get_hash_recalc helper") d2485c4242a8 ("bpf: add bpf_skb_change_type helper") 6578171a7ff0 ("bpf: add bpf_skb_change_proto helper") Changes detected by the tools build system: $ make -C tools/perf O=/tmp/build/perf install-bin make: Entering directory '/home/acme/git/linux/tools/perf' BUILD: Doing 'make -j4' parallel build Warning: tools/include/uapi/linux/bpf.h differs from kernel INSTALL GTK UI CC /tmp/build/perf/bench/mem-memcpy-x86-64-asm.o $ Cc: Adrian Hunter Cc: Alexei Starovoitov Cc: Brenden Blanco Cc: Daniel Borkmann Cc: David Ahern Cc: David S.
