OpenSSH and FIPS 140-2

[Christian S. Perone]

Does anyone knows why in some OpenSSH patches for FIPS we have something like:

SSLeay_add_all_algorithms();
if (FIPS_mode() && !FIPSCHECK_verify(NULL, NULL)) {
                fprintf(stderr,
                    "FIPS integrity verification test failed.\n");
                exit(3);
}

This block of code is always in main() soon after starting
service/client. Why are they checking FIPS_mode() if the
FIPS_mode_set() wasn't even called before that ? The
SSLeay_add_all_algorithms() is supposed call FIPS_mode_set() ?
Another question I have is why are they using FIPSCHECK_verify() from
libfipscheck if the FIPS_mode_set() already check the incore
fingerprint when called. Is this another requirement from FIPS 140-2 ?

Great thanks !
