Subject: [PATCH 00/25] selftests/ftrace: Improve ftracetest with coverage check
Date: Fri, 27 Jul 2018 21:09:56 +0900 [thread overview]
Message-ID: <153269339575.3084.16279591141931053689.stgit@devbox> (raw)
Hello,
Here is a series of patches for improving ftracetest testcase
using gcov/lcov. It is still in progress, and I have got good
improvement of line/function coverage under kernel/trace with
this series. (Note that this kernel enables ftrace startup
tests)
Without this series
Lines: 10156 17200 59.0 %
Functions: 1069 1772 60.3 %
With this series
Lines: 11130 17200 64.7 %
Functions: 1185 1772 66.9 %
Of course we don't need to make it 100%, because ftracetest
is a function/specification test, and there are functions and
lines which never be called (like critical error detection :) ).
Also, ftrace has some amount of code for perf and bpf subsystem
which should be tested by perf/bpf tests.
However, GCOV(LCOV) gives us a good insight into which
functions are covered or not covered by the test cases.
This series has some ftracetest framework improvements too,
which are for debugging ftracetest itself.
Tracing/Gcov-kernel:
- Add CONFIG_GCOV_PROFILE_FRACE, which enables gcov profiling
only on tracing subsystem (under kernel/trace/). This may not
needed for everyone (like a debugging feature).
So it can be dropped anyway.
Ftracetest framework improvements:
- Add --stop-fail for detecting failure soon.
- Add --console for interactively debugging a testcase by shell.
- Add testcase-number prefix to logfile for finding log easier.
- Improve general init function
- Call general init function after all testcases.
- Remove init/cleanup code from all testcase (since general init
function will fixed it up)
Testcase fixes:
- Fix to check $comm availability.
- Make checkbashisms clean
Testcase improvements:
- Use loopback address instead of localhost
- Improve kprobe on module testcase to load/unload module
- Improve kprobe testcase to check log data
- Improve kretprobe testcase to check log data
- Test kprobe-event argument with various bitsize
- Check set_event_pid result
Adding testcases:
- Add kprobe event with $comm argument testcase
- Add kprobe profile testcase
- Add kprobe-event with symbol argument test
- Add nop tracer testcase
- Add trace_printk sample module testcase
- Add ringbuffer size changing testcase
- Add function profiling statistics testcase
- Add max stack tracer testcase
- Add function filter on module testcase
- Add trace_pipe testcase
TBD:
Following testcase improvements are remaining.
- Checking of various supported types (like u8, u64 etc.)
testcases
- Filter actions for ftrace testcases
Thank you,
