2019-08-26perf trace beauty ioctl: Fix off-by-one error in cmd->string tableBenjamin Peterson1-1/+1
While tracing a program that calls isatty(3), I noticed that strace reported TCGETS for the request argument of the underlying ioctl(2) syscall while perf trace reported TCSETS. strace is corrrect. The bug in perf was due to the tty ioctl beauty table starting at 0x5400 rather than 0x5401. Committer testing: Using augmented_raw_syscalls.o and settings to make 'perf trace' use strace formatting, i.e. with this in ~/.perfconfig # cat ~/.perfconfig [trace] add_events = /home/acme/git/linux/tools/perf/examples/bpf/augmented_raw_syscalls.c show_zeros = yes show_duration = no no_inherit = yes show_timestamp = no show_arg_names = no args_alignment = 40 show_prefix = yes # strace -e ioctl stty > /dev/null ioctl(0, TCGETS, {B38400 opost isig icanon echo ...}) = 0 ioctl(1, TIOCGWINSZ, 0x7fff8a9b0860) = -1 ENOTTY (Inappropriate ioctl for device) ioctl(1, TCGETS, 0x7fff8a9b0540) = -1 ENOTTY (Inappropriate ioctl for device) +++ exited with 0 +++ # Before: # perf trace -e ioctl stty > /dev/null ioctl(0, TCSETS, 0x7fff2cf79f20) = 0 ioctl(1, TIOCSWINSZ, 0x7fff2cf79f40) = -1 ENOTTY (Inappropriate ioctl for device) ioctl(1, TCSETS, 0x7fff2cf79c20) = -1 ENOTTY (Inappropriate ioctl for device) # After: # perf trace -e ioctl stty > /dev/null ioctl(0, TCGETS, 0x7ffed0763920) = 0 ioctl(1, TIOCGWINSZ, 0x7ffed0763940) = -1 ENOTTY (Inappropriate ioctl for device) ioctl(1, TCGETS, 0x7ffed0763620) = -1 ENOTTY (Inappropriate ioctl for device) # Signed-off-by: Benjamin Peterson <benjamin@python.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Fixes: 1cc47f2d46206d67285aea0ca7e8450af571da13 ("perf trace beauty ioctl: Improve 'cmd' beautifier") Link: http://lkml.kernel.org/r/20190823033625.18814-1-benjamin@python.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2019-08-22libperf: Fix alignment trap with xyarray contents in 'perf stat'Gerald BAEZA1-1/+2
Following the patch 'perf stat: Fix --no-scale', an alignment trap happens in process_counter_values() on ARMv7 platforms due to the attempt to copy non 64 bits aligned double words (pointed by 'count') via a NEON vectored instruction ('vld1' with 64 bits alignment constraint). This patch sets a 64 bits alignment constraint on 'contents[]' field in 'struct xyarray' since the 'count' pointer used above points to such a structure.
