Hi Tom, Here is a series of patches which applies common error_log framework to probe events. While applying it, I found I missed to check some errors in parser. Also, I made a testcase for this feature (only for kprobe event side, please make your test for the hist errors too). Thus I made this as a series which contains some bugfixes (a kind of hardening), cleanups, and a test besides of the main patch.
Please feel free to pick this series to your series. I think some bugfixes might be better to push Steve's urgent branch. Let's talk with Steve. Oh, note that this series can be applied on your v3 series, except for [4/5] :) 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 kprobe errors kernel/trace/trace_kprobe.c | 90 ++++-- kernel/trace/trace_probe.c | 280 +++++++++++++++----- kernel/trace/trace_probe.h | 76 +++++ kernel/trace/trace_uprobe.c | 43 ++- .../ftrace/test.d/kprobe/kprobe_syntax_errors.tc | 91 +++++++ 5 files changed, 449 insertions(+), 131 deletions(-) create mode 100644 tools/testing/selftests/ftrace/test.d/kprobe/kprobe_syntax_errors.tc -- Masami Hiramatsu <mhira...@kernel.org>
