But from a glance, I think it's failing in your run because there are checks with and without TCP_AO, but I didn't think of checking for the hashing algorithms support. I think what happens is has_tcp_ao(): : strcpy(tmp.alg_name, "hmac(sha1)"); ... : if (setsockopt(sk, IPPROTO_TCP, TCP_AO_ADD_KEY, &tmp, sizeof(tmp)) < 0) Could you check that what I suppose is failing, is actually failing? [dima@Mindolluin linux-master]$ grep -e '\<CONFIG_CRYPTO_SHA1\>' -e '\<CONFIG_CRYPTO_HMAC\>' .config CONFIG_CRYPTO_HMAC=y CONFIG_CRYPTO_SHA1=y If that's the case, I'll add the detection for hashing algorithms to lib/kconfig.c (together with a patch for tools/testing/selftests/net/config). And also heads up for key-management.c - that tries a bunch of hashing algorithms to check that the work and that the key rotation between different algorithms works: : const char *test_algos[] = { : "cmac(aes128)", : "hmac(sha1)", "hmac(sha512)", "hmac(sha384)", "hmac(sha256)", : "hmac(sha224)", "hmac(sha3-512)", : /* only if !CONFIG_FIPS */ : #define TEST_NON_FIPS_ALGOS 2 : "hmac(rmd160)", "hmac(md5)" : }; > The script does: > > target=net/tcp_ao > make mrproper > > vng -v -b -f tools/testing/selftests/$target > # build the scripts > make headers > make -C tools/testing/selftests/$target > > vng -v -r arch/x86/boot/bzImage --user root > # inside the VM > make -C tools/testing/selftests TARGETS=$target run_tests Thanks, Dmitry
