4e790e074f Move hexdump to verbose level 2 
From the command line you use two "-v" options or in the configuration
file you replace the boolean "verbose:true" with an integer "verbose:2".

021eb836e4 Adjust linking so that wrapper libraries are static. 2017-11-23 20:51:57 +00:00
Robert de Bath
cb90cc97ae Default to using libpcre and actually use it 
as libpcre has to better binary support.

Note, just linking libpcre only has no effect, the posix functions are
provided by libpcreposix.

Use "make USELIBPCRE=" to turn libpcre off and link POSIX library.

338daafe87 Use REG_EXTENDED for regex matching 
The "7 regex" manual page called 'Basic' regular expressions "Obsolete".

It also matches the pcre expressions slightly better.

1f98b97756 Allow SSLv2 CLIENT-HELLO (without SSL 2.0) 
The existing TLS probe is documented to ignore SSL 2.0, citing RFC 6176 as a reason.
RFC 6176 does prohibit the usage of SSL 2.0, but does allow for ClientHello messages
in the version 2 CLIENT-HELLO format (as long as those are used to negotiate the use
of a higher protocol).

This commit extends the TLS probe, by making it accept SSL v2 ClientHello messages
that negotiate a version of SSL/TLS 1.0 or higher (which is the same version range
as the original code).

a3df50f31f sslh-select: fix connections with deferred data after connect_queue 
Previously, if some data was still deferred after the connect_queue
call, the server side of the connection would never start being
monitored for reads, while the client side kept being monitored
and new data from the client could be sent to the server before
the previously deferred data.

2a76b520d5 Add better documentation of transparent proxy support. 
This allows for some more generalized configs.
You don't need to specify ports anymore and still can
connect directly to the running services if you want.

It also allows you to use "localhost" as destination in your sslh config,
something that wasn't possible with the old scheme.

70a2ea926e Makefile: fix parallel build 
version.h is included by some .o files, but it is generated. As such, it
must be a dependency of those .o files.

Rather than filter exactly which .o file needs it, just add a generic
dependency for all .o files on version.h.
