[PATCH v3] selftest/vm: add mremap expand merge offset test

by Lorenzo Stoakes

Add a test to assert that we can mremap() and expand a mapping starting from an offset within an existing mapping. We unmap the last page in a 3 page mapping to ensure that the remap should always succeed, before remapping from the 2nd page. This is additionally a regression test for the issue solved in "mm, mremap: fix mremap() expanding vma with addr inside vma" and confirmed to fail prior to the change and pass after it. Finally, this patch updates the existing mremap expand merge test to check error conditions and reduce code duplication between the two tests.

This patchset will fix a false-positive issue caused by the command in cleanup_v6() of the arp_ndisc_evict_nocarrier test. Also, it will make the test to return a non-zero value for any failure reported in the test for us to avoid false-negative results.

[PATCH] selftests: net: fix cmsg_so_mark.sh test hang

by Po-Hsu Lin

This cmsg_so_mark.sh test will hang on non-amd64 systems because of the infinity loop for argument parsing in cmsg_sender. Variable "o" in cs_parse_args() for taking getopt() should be an int, otherwise it will be 255 when getopt() returns -1 on non-amd64 system and thus causing infinity loop.

[PATCH bpf-next] selftests/bpf: move struct definitions out of function params

by James Hilliard

Anonymous structs can't be declared inside function parameter definitions in current c standards, however clang doesn't detect this condition currently while GCC does.
