This is helpful for systems where fast startup time is important. It is especially nice to avoid benchmarking RAID functions that are never used (for example, BTRFS selects RAID6_PQ even if the parity RAID mode is not in use). This saves 250+ milliseconds of boot time on modern x86 and ARM systems with a dozen or more available implementations. The new option is defaulted to 'y' to match the previous behavior of always benchmarking on init.

2019-12-31arm64: Don't unconditionally add -Wno-psabi to KBUILD_CFLAGSsubmit/tizen/20200102.014302accepted/tizen/unified/20200102.220851Nathan Chancellor1-1/+1
commit fa63da2ab046b885a7f70291aafc4e8ce015429b upstream. This is a GCC only option, which warns about ABI changes within GCC, so unconditionally adding it breaks Clang with tons of: warning: unknown warning option '-Wno-psabi' [-Wunknown-warning-option] and link time failures: ld.lld: error: undefined symbol: __efistub___stack_chk_guard >>> referenced by arm-stub.c:73 (/home/nathan/cbl/linux/drivers/firmware/efi/libstub/arm-stub.c:73) >>> arm-stub.stub.o:(__efistub_install_memreserve_table) in archive ./drivers/firmware/efi/libstub/lib.a These failures come from the lack of -fno-stack-protector, which is added via cc-option in drivers/firmware/efi/libstub/Makefile. When an unknown flag is added to KBUILD_CFLAGS, clang will noisily warn that it is ignoring the option like above, unlike gcc, who will just error. $ echo "int main() { return 0; }" > tmp.c $ clang -Wno-psabi tmp.c; echo $? warning: unknown warning option '-Wno-psabi' [-Wunknown-warning-option] 1 warning generated. 0 $ gcc -Wsometimes-uninitialized tmp.c; echo $? gcc: error: unrecognized command line option ‘-Wsometimes-uninitialized’; did you mean ‘-Wmaybe-uninitialized’? 1 For cc-option to work properly with clang and behave like gcc, -Werror is needed, which was done in commit c3f0d0bc5b01 ("kbuild, LLVMLinux: Add -Werror to cc-option to support clang"). $ clang -Werror -Wno-psabi tmp.c; echo $? error: unknown warning option '-Wno-psabi' [-Werror,-Wunknown-warning-option] 1 As a consequence of this, when an unknown flag is unconditionally added to KBUILD_CFLAGS, it will cause cc-option to always fail and those flags will never get added: $ clang -Werror -Wno-psabi -fno-stack-protector tmp.c; echo $? error: unknown warning option '-Wno-psabi' [-Werror,-Wunknown-warning-option] 1 This can be seen when compiling the whole kernel as some warnings that are normally disabled (see below) show up. The full list of flags missing from drivers/firmware/efi/libstub are the following (gathered from diffing .arm64-stub.o.cmd): -fno-delete-null-pointer-checks -Wno-address-of-packed-member -Wframe-larger-than=2048 -Wno-unused-const-variable -fno-strict-overflow -fno-merge-all-constants -fno-stack-check -Werror=date-time -Werror=incompatible-pointer-types -ffreestanding -fno-stack-protector Use cc-disable-warning so that it gets disabled for GCC and does nothing for Clang.

2019-12-31arm64: Silence gcc warnings about arch ABI driftDave Martin1-0/+1
[ Upstream commit ebcc5928c5d925b1c8d968d9c89cdb0d0186db17 ] Since GCC 9, the compiler warns about evolution of the platform-specific ABI, in particular relating for the marshaling of certain structures involving bitfields. The kernel is a standalone binary, and of course nobody would be so stupid as to expose structs containing bitfields as function arguments in ABI. (Passing a pointer to such a struct, however inadvisable, should be unaffected by this change. perf and various drivers rely on that.) So these warnings do more harm than good: turn them off. We may miss warnings about future ABI drift, but that's too bad. Future ABI breaks of this class will have to be debugged and fixed the traditional way unless the compiler evolves finer-grained diagnostics.

2019-12-31tracing: Silence GCC 9 array bounds warningMiguel Ojeda3-10/+20
commit 0c97bf863efce63d6ab7971dad811601e6171d2f upstream. Starting with GCC 9, -Warray-bounds detects cases when memset is called starting on a member of a struct but the size to be cleared ends up writing over further members. Such a call happens in the trace code to clear, at once, all members after and including `seq` on struct trace_iterator: In function 'memset', inlined from 'ftrace_dump' at kernel/trace/trace.c:8914:3: ./include/linux/string.h:344:9: warning: '__builtin_memset' offset [8505, 8560] from the object at 'iter' is out of the bounds of referenced subobject 'seq' with type 'struct trace_seq' at offset 4368 [-Warray-bounds] 344 | return __builtin_memset(p, c, size); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ In order to avoid GCC complaining about it, we compute the address ourselves by adding the offsetof distance instead of referring directly to the member. Since there are two places doing this clear (trace.c and trace_kdb.c), take the chance to move the workaround into a single place in the internal header.

commit cf676908846a06443fa5e6724ca3f5dd7460eca1 upstream. I'm not sure what made gcc warn about this code now. The 'ret' variable does end up initialized in all cases, but it's definitely not obvious, so the compiler is quite reasonable to warn about this. So just add initialization to make it all much more obvious both to compilers and to humans.

2019-12-23perf help: Remove needless use of strncpy()Arnaldo Carvalho de Melo1-1/+1
commit b6313899f4ed2e76b8375cf8069556f5b94fbff0 upstream. Since we make sure the destination buffer has at least strlen(orig) + 1, no need to do a strncpy(dest, orig, strlen(orig)), just use strcpy(dest, orig). This silences this gcc 8.2 warning on Alpine Linux: In function 'add_man_viewer', inlined from 'perf_help_config' at builtin-help.c:284:3: builtin-help.c:192:2: error: 'strncpy' output truncated before terminating nul copying as many bytes from a string as its length [-Werror=stringop-truncation] strncpy((*p)->name, name, len); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ builtin-help.c: In function 'perf_help_config': builtin-help.c:187:15: note: length computed here size_t len = strlen(name); ^~~~~~~~~~~~ Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Fixes: 078006012401 ("perf_counter tools: add in basic glue from Git") Link: https://lkml.kernel.org/n/tip-2f69l7drca427ob4km8i7kvo@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> [sw0312.kim: cherry-pick stable linux-4.19.y commit 0bf5d53b53c8 for gcc 9 build] Signed-off-by: Seung-Woo Kim <sw0312.kim@samsung.com> Change-Id: Id98e9ca8049d25d658b4f012fdede1b8745d875f
2019-12-23perf header: Fix unchecked usage of strncpy()Arnaldo Carvalho de Melo1-1/+1
commit 5192bde7d98c99f2cd80225649e3c2e7493722f7 upstream. The strncpy() function may leave the destination string buffer unterminated, better use strlcpy() that we have a __weak fallback implementation for systems without it. This fixes this warning on an Alpine Linux Edge system with gcc 8.2: util/header.c: In function 'perf_event__synthesize_event_update_name': util/header.c:3625:2: error: 'strncpy' output truncated before terminating nul copying as many bytes from a string as its length [-Werror=stringop-truncation] strncpy(ev->data, evsel->name, len); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ util/header.c:3618:15: note: length computed here size_t len = strlen(evsel->name); ^~~~~~~~~~~~~~~~~~~ Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Fixes: a6e5281780d1 ("perf tools: Add event_update event unit type") Link: https://lkml.kernel.org/n/tip-wycz66iy8dl2z3yifgqf894p@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> [sw0312.kim: cherry-pick stable linux-4.19.y commit 6461a4543b34 for gcc 9 build] Signed-off-by: Seung-Woo Kim <sw0312.kim@samsung.com> Change-Id: I2d116858af62b094276699c790b7ba090fe28513
