A proxy will be able to borrow parameters from another one.
In particular, the filters will be inheritable from another
proxy, and the backend parameters too.
Using the cttproxy kernel patch, it's possible to bind to any source
address. It is highly recommended to use the 03-natdel patch with the
other ones.
A new keyword appears as a complement to the "source" keyword : "usesrc".
The source address is mandatory and must be valid on the interface which
will see the packets. The "usesrc" option supports "client" (for full
client_ip:client_port spoofing), "client_ip" (for client_ip spoofing)
and any 'IP[:port]' combination to pretend to be another machine.
Right now, the source binding is missing from server health-checks if
set to another address. It must be implemented (think restricted firewalls).
The doc is still missing too.
As suggested by Markus Elfring, a few "const char *" have replaced
some "char *" declarations where a function is not expected to
modify a value. It does not change the code but it helps detecting
coding errors.
It is now possible to tarpit connections based on regex matches.
The tarpit timeout is equal to the contimeout. A 500 server error
response is faked, and the logs show the status flags as "PT" which
indicate the connection has been tarpitted.
This makes it possible to relay SSL connections in pure TCP instances while
ensuring the remote end really receives our data eventhough intermediate
agents (firewalls, proxies, ...) might acknowledge the connection.
Too many problem reports were caused by missing timeouts. While
there has never been any default value since version 1.0, having
no timeout is abnormal in networked environments, and will lead
to various problems such as CLOSE_WAIT sockets accumulating and
nasty things like this. For this reason, it's better to annoy
the users until they fix their configs than letting them run
buggy configurations.
The files are now stored under :
- include/haproxy for the generic includes
- include/types.h for the structures needed within prototypes
- include/proto.h for function prototypes and inline functions
- src/*.c for the C files
Most include files are now covered by LGPL. A last move still needs
to be done to put inline functions under GPL and not LGPL.
Version has been set to 1.3.0 in the code but some control still
needs to be done before releasing.
