selftests: firmware: Fix it to do root uid check and skip

2020-01-17T18:49:04Z

[ Upstream commit c65e41538b04e0d64a673828745a00cb68a24371 ] firmware attempts to load test modules that require root access and fail. Fix it to check for root uid and exit with skip code instead.

selftests: loopback.sh: skip this test if the driver does not support

2020-01-17T18:48:20Z

commit cc7e3f63d7299dd1119be39aa187b867d6f8aa17 upstream. The loopback feature is only supported on a few drivers like broadcom, mellanox, etc. The default veth driver has not supported it yet. To avoid returning failed and making the runner feel confused, let's just skip the test on drivers that not support loopback.

[ Upstream commit d187801d1a46519d2a322f879f7c8f85c685372e ] If a timeout failure occurs, kselftest kills the test process and prints the timeout log. If the test process has killed while printing a log that ends with new line, the timeout log can be printed in middle of the test process output so that it can be seems like a comment, as below: # test_process_log not ok 3 selftests: timers: nsleep-lat # TIMEOUT This commit avoids such problem by printing one more line before the TIMEOUT failure log.

selftests/ftrace: Fix multiple kprobe testcase

2020-01-12T11:21:19Z

[ 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
