Hi Dmitry!

I put TCP_AO and VETH in the config and the tests seem to fail with

selftests: net/tcp_ao: rst_ipv4
not ok 1 # error 834[lib/kconfig.c:143] Failed to initialize kconfig 2: No such file or directory
# Planned tests != run tests (0 != 1)
# Totals: pass:0 fail:0 xfail:0 xpass:0 skip:0 error:1

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 for wiring it up and for https://netdev.bots.linux.dev/status.html!

Hehe, yeah I wanted to detect kernels with !CONFIG_TCP_AO, to SKIP the
test, rather than FAIL it, which this lib/kconfig.c does.
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)"
: };

FWIW the config used is uploaded with the results. If you click on 
the remote it should take you to a location like this:

https://netdev-2.bots.linux.dev/vmksft-tcp-ao/results/435369/

and there should be a config file in there.

I was stuck in a meeting and I started playing around with the options 
for TCP-AO :) I added these options now:

CONFIG_CRYPTO_HMAC=y
CONFIG_CRYPTO_SHA1=y
CONFIG_CRYPTO_RMD160=y
CONFIG_IPV6=y
CONFIG_TCP_AO=y
CONFIG_TCP_MD5SIG=y
CONFIG_VETH=m

And it looks much better! There are still some failures:

https://netdev.bots.linux.dev/contest.html?branch=net-next-2024-01-24--18-00&executor=vmksft-tcp-ao

I added VRF so that should hopefully take care of the MD5 skips
on the next run. But the failures of the rst-ip* tests don't look 
like an obvious config problem.

Haha, the same: 3 hour-long meetings for today :-/

Wow! Nice, thank you!

Yep, I'll look into this this week.
