Hi,
This series implements an option to show symbols in _text+OFFSET
format instead of symbol name in the function profiler.
This is the 5th version, the previous one is here;
https://lore.kernel.org/all/176071773144.175601.17884676964675287059.stgit@devnote2/
In this version, eventually I repaced TRACE_ITER_* enumalation
symbols with TRACE_ITER(flag) macro. If the flag bit number is
-1, the macro becomes 0, which is for a dummy flag.
Thank you,

To add a new option, we need to expand it. So replace the TRACE_ITER_##flag with TRACE_ITER(flag) macro which is 64bit bitmask. Signed-off-by: Masami Hiramatsu (Google) <mhiramat@kernel.org> --- Changes in v5: - Use TRACE_ITER() macro. Changes in v4: - Use enum ... : type {} instead of const variables. Changes in v3: - Make TRACE_ITER_* to global. --- kernel/trace/blktrace.c | 6 + kernel/trace/trace.c | 151 +++++++++++++++++----------------- kernel/trace/trace.h | 29 +++---- kernel/trace/trace_events.c | 4 - kernel/trace/trace_events_synth.c | 2 kernel/trace/trace_fprobe.c | 6 + kernel/trace/trace_functions_graph.c | 18 ++-- kernel/trace/trace_irqsoff.c | 30 +++---- kernel/trace/trace_kdb.c | 2 kernel/trace/trace_kprobe.c | 6 + kernel/trace/trace_output.c | 18 ++-- kernel/trace/trace_sched_wakeup.c | 24 +++-- kernel/trace/trace_syscalls.c | 2 13 files changed, 148 insertions(+), 150 deletions(-) diff --git a/kernel/trace/blktrace.c b/kernel/trace/blktrace.c index 6941145b5058..e21176f396d5 100644 --- a/kernel/trace/blktrace.c +++ b/kernel/trace/blktrace.c @@ -1452,7 +1452,7 @@ static enum print_line_t print_one_line(struct trace_iterator *iter, t = te_blk_io_trace(iter->ent);

However, there are some same-name local symbols, which we can not distinguish. To solve this issue, this introduces an option to show the symbols in "_text+OFFSET" format. This can avoid exposing the random shift of KASLR. The functions in modules are shown as "MODNAME+OFFSET" where the offset is from ".text". E.g. for the kernel text symbols, specify vmlinux and the output to addr2line, you can find the actual function and source info; $ addr2line -fie vmlinux _text+3078208 __balance_callbacks kernel/sched/core.c:5064 for modules, specify the module file and .text+OFFSET; $ addr2line -fie samples/trace_events/trace-events-sample.ko .text+8224 do_simple_thread_func samples/trace_events/trace-events-sample.c:23 Suggested-by: Steven Rostedt (Google) <rostedt@goodmis.org> Signed-off-by: Masami Hiramatsu (Google) <mhiramat@kernel.org> --- Changes in v5: - Update dummy flag according to new macros.

Hi,
This series implements an option to show symbols in _text+OFFSET
format instead of symbol name in the function profiler.
This is the 6th version, the previous one is here;
https://lore.kernel.org/all/176114747153.315239.6863821259073466010.stgit@devnote2/
This version is rebased on top of linux-trace/for-next branch
and modify offset format to hex.
Thank you,
