selftests/bpf: Free the allocated resources after test case succeeds 2022-09-22T23:41:27+00:00 Hou Tao houtao1@huawei.com 2022-09-21T07:00:35+00:00 103d002fb7d548fb1187e350f2b73788558128b9 Free the created fd or allocated bpf_object after test case succeeds, else there will be resource leaks.

Free the created fd or allocated bpf_object after test case succeeds,
else there will be resource leaks.

Spotted by using address sanitizer and checking the content of

selftests/bpf: Migrate selftests to bpf_map_create() 2021-11-25T22:37:38+00:00 Andrii Nakryiko andrii@kernel.org 2021-11-24T19:32:33+00:00 2fe256a429cb6c0b0064563af4158470143a363c Conversion is straightforward for most cases. In few cases tests are using mutable map_flags and attribute structs, but bpf_map_create_opts can be used in the similar fashion, so there were no problems. Just lots of repetitive conversions.
