LinkAuth method 1 is the one where we pull the TLS master secrets
out of the OpenSSL data structures and authenticate them with
RSA. Right now we list method 1 as required for clients and relays.
That's a problem, since we can't reasonably support it with NSS. So
let's remove it as a requirement and a recommendation.
As for method 3: I'd like to recommend it it, but that would make
0.2.9 start warning. Let's not do that till at least some time
after 0.3.5 (the next LTS) is stable.
Closes ticket 27286
Instead, count exits as usable if they have the exit flag, and
present if they also have a non-reject exit policy.
Requiring a threshold of usable descriptors avoids directories trickling
exit descriptors to clients to discover their ExitNodes settings.
Part of 27236.
Previously, Tor would only check the exit flag. In small networks, Tor
could bootstrap once it received a consensus with exits, without fetching
the new descriptors for those exits.
After bootstrap, Tor delays descriptor fetches, leading to failures in
fast networks like chutney.
Fixes 27236; bugfix on 0.2.6.3-alpha.
Unlike the old test, this test no will no longer mess around with
the forbidden internals of any openssl data structures.
Additionally, it verifies several other behaviors of
tor_tls_cert_matches_key() that we had wanted to verify, such as
the possibility of the certificate's key not matching.
Fixes bug 27226; bugfix on 0.2.5.1-alpha.
This allows us to mock our own tor_tls_get_peer_certificate()
function in order to test ..cert_matches_key(), which will in turn
allow us to simplify test_tortls_cert_matches_key() considerably.
Prep work for the fix for 27226.
It's impossible for spaces to get here, since spaces are used as
separators between individual protocol entries higher up.
And it shouldn't ignore whitespace that isn't a literal space
character, because that would differ from the C implementation.
These were added in 9925d2e687.
Fixes#27177. Bugfix on 0.3.3.5-rc.
It was parsing "1-2-3" as if it were 1-2, ignoring the 2nd hyphen
and everything after.
Introduced in d1820c1516.
Fixes#27164; bugfix on 0.3.3.1-alpha.
