selftests/net: remove ARRAY_SIZE define from individual tests

2021-12-11T00:50:57Z

ARRAY_SIZE is defined in several selftests. Remove definitions from individual test files and include header file for the define instead. ARRAY_SIZE define is added in a separate patch to prepare for this change. Remove ARRAY_SIZE from net tests and pickup the one defined in kselftest.h. Signed-off-by: Shuah Khan

selftests/net: rxtimestamp: fix clang issues for target arch PowerPC

2020-07-27T19:56:58Z

The signedness of char is implementation-dependent. Some systems (including PowerPC and ARM) use unsigned char.

selftests/net: update initializer syntax to use c99 designators

2020-07-05T00:55:20Z

Before, clang version 9 threw errors such as: error: use of GNU old-style field designator extension [-Werror,-Wgnu-designator] { tstamp: true, swtstamp: true } ^~~~~~~ .tstamp = Fix these warnings in tools/testing/selftests/net in the same manner as commit 121e357ac728 ("selftests/harness: Update named initializer syntax"). N.B. rxtimestamp.c is the only affected file in the directory. Signed-off-by: Tanner Love Acked-by: Willem de Bruijn Signed-off-by: David S. Miller

selftests/net: add ipv6 test coverage in rxtimestamp test

2020-07-03T21:38:20Z

Add the options --ipv4, --ipv6 to specify running over ipv4 and/or ipv6. If neither is specified, then run both. Signed-off-by: Tanner Love Acked-by: Willem de Bruijn Signed-off-by: David S. Miller

selftests/net: plug rxtimestamp test into kselftest framework

2020-06-24T03:36:46Z

Run rxtimestamp as part of TEST_PROGS. Analogous to other tests, add new rxtimestamp.sh wrapper script, so that the test runs isolated from background traffic in a private network namespace. Also ignore failures of test case #6 by default. This case verifies that a receive timestamp is not reported if timestamp reporting is enabled for a socket, but generation is disabled. Receive timestamp generation has to be enabled globally, as no associated socket is known yet. A background process that enables rx timestamp generation therefore causes a false positive. Ntpd is one example that does. Add a "--strict" option to cause failure in the event that any test case fails, including test #6. This is useful for environments that are known to not have such background processes.

selftests/net: in rxtimestamp getopt_long needs terminating null entry

getopt_long requires the last element to be filled with zeros. Otherwise, passing an unrecognized option can cause a segfault.

selftests: move timestamping selftests to net folder
