If the value for the Divert option is not yes|no, it is assumed to be a
Divert filtering rule. So the parser for filtering rules should issue
any errors.
(Divert|Split|Pass|Block)
([from (
user (username|*) [desc keyword]|
ip (clientaddr|*)|
*)]
[to (
sni (servername[*]|*)|
cn (commonname[*]|*)|
host (host[*]|*)|
uri (uri[*]|*)|
ip (serveraddr|*)|
*)]
|*)
Also, fix a couple of issues with filter rule handling
Clean up
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 global opts strings in this new tmp struct are used while cloning
global opts into proxyspec opts. A var of this type is passed around as
a flag to indicate if these opts are global (if non-NULL), so should be
stored in that struct and used as such, or proxyspec specific (if NULL),
so should not be used as global. This var is temporary, hence freed
immediately after configuration is complete.
Also improve and clean up.
