Subject: [PATCH 0/3] Perf UBsan Patches
Date: Wed, 24 Jul 2019 11:45:09 -0700 [thread overview]
Message-ID: <20190724184512.162887-1-nums@google.com> (raw)
These patches are all errors found by running perf test with the
ubsan (undefined behavior sanitizer version of perf).
To repro the bug fixed in the "Fix insn.c misaligned address
error" patch you must first apply the changes in the
Fix backward-ring-buffer.c format-truncation error and
Fix ordered-events.c array-bounds error patches since these
are necessary to get the ubsan version of perf to build.
To build the ubsan version, run:
make -C tools/perf USE_CLANG=1 EXTRA_CFLAGS="-fsanitize=undefined"
Numfor Mbiziwo-Tiapo (3):
Fix backward-ring-buffer.c format-truncation error
Fix ordered-events.c array-bounds error
Fix insn.c misaligned address error
