selftests/ftrace: Return unsupported if no error_log file

2020-06-17T14:40:35+00:00

commit 619ee76f5c9f6a1d601d1a056a454d62bf676ae4 upstream. Check whether error_log file exists in tracing/error_log testcase and return UNSUPPORTED if no error_log file. This can happen if we run the ftracetest on the older stable kernel.

selftests/ftrace: Check the first record for kprobe_args_type.tc

2020-05-20T06:20:14+00:00

[ Upstream commit f0c0d0cf590f71b2213b29a7ded2cde3d0a1a0ba ] It is possible to get multiple records from trace during test and then more than 4 arguments are assigned to ARGS. This situation results in the failure of kprobe_args_type.tc. For example: ----------------------------------------------------------- grep testprobe trace ftracetest-5902 [001] d... 111195.682227: testprobe: (_do_fork+0x0/0x460) arg1=334823024 arg2=334823024 arg3=0x13f4fe70 arg4=7 pmlogger-5949 [000] d... 111195.709898: testprobe: (_do_fork+0x0/0x460) arg1=345308784 arg2=345308784 arg3=0x1494fe70 arg4=7 grep testprobe trace sed -e 's/.* arg1=$.*$ arg2=$.*$ arg3=$.*$ arg4=$.*$/\1 \2 \3 \4/' ARGS='334823024 334823024 0x13f4fe70 7 345308784 345308784 0x1494fe70 7' ----------------------------------------------------------- We don't care which process calls do_fork so just check the first record to fix the issue.

selftests/ftrace: Fix multiple kprobe testcase

2020-01-12T11:21:19+00:00

[ Upstream commit 5cc6c8d4a99d0ee4d5466498e258e593df1d3eb6 ] Fix multiple kprobe event testcase to work it correctly. There are 2 bugfixes. - Since `wc -l FILE` returns not only line number but also FILE filename, following "if" statement always failed. Fix this bug by replacing it with 'cat FILE | wc -l' - Since "while do-done loop" block with pipeline becomes a subshell, $N local variable is not update outside of the loop. Fix this bug by using actual target number (256) instead of $N. Signed-off-by: Masami Hiramatsu Reviewed-by: Steven Rostedt (VMware) Signed-off-by: Shuah Khan Signed-off-by: Sasha Levin

selftests/ftrace: Do not to use absolute debugfs path

2020-01-12T11:21:19+00:00

[ Upstream commit ba1b9c5048e43716921abe3a1db19cebebf4a5f5 ] Use relative path to trigger file instead of absolute debugfs path, because if the user uses tracefs instead of debugfs, it can be mounted at /sys/kernel/tracing. Anyway, since the ftracetest is designed to be run at the tracing directory, user doesn't need to use absolute path.

selftests/ftrace: Fix ftrace test cases to check unsupported

2020-01-12T11:21:19+00:00

[ Upstream commit 25deae098e748d8d36bc35129a66734b8f6925c9 ] Since dynamic function tracer can be disabled, set_ftrace_filter can be disappeared. Test cases which depends on it, must check whether the set_ftrace_filter exists or not before testing and if not, return as unsupported. Also, if the function tracer itself is disabled, we can not set "function" to current_tracer. Test cases must check it before testing, and return as unsupported.

selftests/ftrace: Fix to check the existence of set_ftrace_filter

2020-01-12T11:21:19+00:00

[ Upstream commit fd1baf6ca2ea3550ea47f2bb0bdcf34ec764a779 ] If we run ftracetest on the kernel with CONFIG_DYNAMIC_FTRACE=n, there is no set_ftrace_filter and all test cases are failed, because reset_ftrace_filter() returns an error. Let's check whether set_ftrace_filter exists in reset_ftrace_filter() and clean up only set_ftrace_notrace in initialize_ftrace().
