End-to-end tests now require testproxy v0.0.4, which supports the new
Reconnect command for the Pass filtering rule.
Split mode with the -n option also supports filtering rules, so the
Divert rule can enable the divert mode even with the -n option. This is
because the purpose of the -n option is to convert sslproxy into an
sslsplit, and we want to support filtering rules in sslsplit-like
sslproxy too.
Now we don't go over all of the passsite rules in a linked list trying
to apply passsite to the sni or common names of a conn. Instead, we now
have user+keyword, keyword, ip, and all lists. For example, if we find
the conn user in the user+keyword list and a passsite in that list
matches, we don't look into other lists.
This change is expected to improve the performance of passsite
processing considerably, because in the earlier implementation we had to
go over all of the passsite rules trying to match passsite.
And this solution uses a correct data structure, even if not the best.
For example, each user or keyword in passsite rules is strdup()'ed only
once.
Note that a better solution could use, say, a hash table for users,
instead of a linked list. But hash tables are not suitable for keywords
or sites, because we search for substring matches with them, not exact
matches.
Also, this fixes passsite rules without any filters defined, i.e. to be
applied to all connections.
Also, now e2e tests error exit if WITHOUT_USERAUTH is enabled. E2e tests
require UserAuth enabled.
The -n command line option enables split mode for all proxyspecs,
effectively making sslproxy behave like sslsplit.
Divert option can be set/unset globally and per-proxyspec.
Add e2e tests for split mode, and update make file for tests
accordingly.
Update documentation accordingly.
Improve code reuse, remove duplicate functions.
This change deserves a release of its own, hence v0.8.4.
The problem with LibreSSL 2.7.4 was not that it didn't support tls10,
but that MEDIUM and HIGH cipher definitions were different from the
openssl version of testproxy, hence tests were failing due to no shared
ciphers
