2019-07-30selftests/livepatch: push and pop dynamic debug configJoe Lawrence
The livepatching self-tests tweak the dynamic debug config to verify the kernel log during the tests. Enhance set_dynamic_debug() so that the config changes are restored when the script exits. Note this functionality needs to keep in sync with: - dynamic_debug input/output formatting - functions affected by set_dynamic_debug() For example, push_dynamic_debug() transforms: kernel/livepatch/transition.c:530 [livepatch]klp_init_transition =_ "'%s': initializing %s transition\012" to the following: file kernel/livepatch/transition.c line 530 =_ Signed-off-by: Joe Lawrence <joe.lawrence@redhat.com> Tested-by: Petr Mladek <pmladek@suse.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
2019-07-30kselftest: save-and-restore errno to allow for %m formattingAleksa Sarai
Previously, using "%m" in a ksft_* format string can result in strange output because the errno value wasn't saved before calling other libc functions. The solution is to simply save and restore the errno before we format the user-supplied format string.

2019-07-27selftests/bpf: add sub-tests support for test_progsAndrii Nakryiko
Allow tests to have their own set of sub-tests. Also add ability to do test/subtest selection using `-t <test-name>/<subtest-name>` and `-n <test-nums-set>/<subtest-nums-set>`, as an extension of existing -t/-n selector options. For the <test-num-set> format: it's a comma-separated list of either individual test numbers (1-based), or range of test numbers. E.g., all of the following are valid sets of test numbers: - 10 - 1,2,3 - 1-3 - 5-10,1,3-4 '/<subtest' part is optional, but has the same format. E.g., to select test #3 and its sub-tests #10 through #15, use: -t 3/10-15. Similarly, to select tests by name, use `-t verif/strobe`: $ sudo ./test_progs -t verif/strobe #3/12 strobemeta.o:OK #3/13 strobemeta_nounroll1.o:OK #3/14 strobemeta_nounroll2.o:OK #3 bpf_verif_scale:OK Summary: 1/3 PASSED, 0 FAILED Example of using subtest API is in the next patch, converting bpf_verif_scale.c tests to use sub-tests.

2019-07-27selftests/bpf: abstract away test log outputAndrii Nakryiko
This patch changes how test output is printed out. By default, if test had no errors, the only output will be a single line with test number, name, and verdict at the end, e.g.: #31 xdp:OK If test had any errors, all log output captured during test execution will be output after test completes. It's possible to force output of log with `-v` (`--verbose`) option, in which case output won't be buffered and will be output immediately. To support this, individual tests are required to use helper methods for logging: `test__printf()` and `test__vprintf()`.

Add a skip() message function that stops the test, logs an explanation, and sets the "skip" return code (4).

The TC filters used in the test do not work with veth devices because the outer Ethertype is 802.1Q and not IPv4. The test passes with mlxsw netdevs since the hardware always looks at "The first Ethertype that does not point to either: VLAN, CNTAG or configurable Ethertype". Fix this by matching on the VLAN ID instead, but on the ingress side. The reason why this is not performed at egress is explained in the commit cited below.

2019-07-22x86/syscalls: Split the x32 syscalls into their own tableAndy Lutomirski
For unfortunate historical reasons, the x32 syscalls and the x86_64 syscalls are not all numbered the same. As an example, ioctl() is nr 16 on x86_64 but 514 on x32. This has potentially nasty consequences, since it means that there are two valid RAX values to do ioctl(2) and two invalid RAX values. The valid values are 16 (i.e. ioctl(2) using the x86_64 ABI) and (514 | 0x40000000) (i.e. ioctl(2) using the x32 ABI). The invalid values are 514 and (16 | 0x40000000). 514 will enter the "COMPAT_SYSCALL_DEFINE3(ioctl, ...)" entry point with in_compat_syscall() and in_x32_syscall() returning false, whereas (16 | 0x40000000) will enter the native entry point with in_compat_syscall() and in_x32_syscall() returning true. Both are bogus, and both will exercise code paths in the kernel and in any running seccomp filters that really ought to be unreachable. Splitting out the x32 syscalls into their own tables, allows both bogus invocations to return -ENOSYS. I've checked glibc, musl, and Bionic, and all of them appear to call syscalls with their correct numbers, so this change should have no effect on them. There is an added benefit going forward: new syscalls that need special handling on x32 can share the same number on x32 and x86_64. This means that the special syscall range 512-547 can be treated as a legacy wart instead of something that may need to be extended in the future. Also add a selftest to verify the new behavior.
