Previous version is here. http://lkml.kernel.org/r/155248005229.10815.334731901778152247.stgit@devnote2 In this version, I've updated some error messages according to Steve's comment, adjust some error position, and update testcase to simplify a bit. - [4/7]: Update error message according to Steve's comment (Thanks!) - [6/7]: Update error message, adjust error positions, and add uprobe errors - [7/7]: Specify error position in command string by "^". Clear error_log right before writing command. Add uprobe syntax error checker Thank you, --- Masami Hiramatsu (7): tracing/probe: Check maxactive error cases tracing/probe: Check event name length correctly tracing/probe: Check the size of argument name and body tracing/probe: Check event/group naming rule at parsing tracing/probe: Verify alloc_trace_*probe() result tracing: Use tracing error_log with probe events selftests/ftrace: Add error_log testcase for probe errors kernel/trace/trace_kprobe.c | 90 ++++-- kernel/trace/trace_probe.c | 282 +++++++++++++++----- kernel/trace/trace_probe.h | 78 +++++- kernel/trace/trace_uprobe.c | 52 ++-- .../ftrace/test.d/kprobe/kprobe_syntax_errors.tc | 93 +++++++ .../ftrace/test.d/kprobe/uprobe_syntax_errors.tc | 31 ++ 6 files changed, 494 insertions(+), 132 deletions(-) create mode 100644 tools/testing/selftests/ftrace/test.d/kprobe/kprobe_syntax_errors.tc create mode 100644 tools/testing/selftests/ftrace/test.d/kprobe/uprobe_syntax_errors.tc -- Masami Hiramatsu <mhiramat@...nel.org>
