e63ac871f8 MINOR: log: Add log-format variable %HQ, to log HTTP query strings
Since sample fetches are not always available in the response phase,
this patch implements %HQ such that:

  GET /foo?bar=baz HTTP/1.0

...would be logged as:

  ?bar=baz

This patch allow the existing operators to take a variable as parameter.
This is useful to add the content of two variables. This patch modify
the behavior of operators.

00c005c726 MEDIUM: sample: switch to saturated arithmetic
This patch check calculus for overflow and returns capped values.
This permits to protect against integer overflow in certain operations
involving ratios, percentages, limits or anything. That can sometimes
be critically important with some operations (eg: content-length < X).

07ee64ef4d MAJOR: sample: converts uint and sint in 64 bits signed integer
This patch removes the 32 bits unsigned integer and the 32 bit signed
integer. It replaces these types by a unique type 64 bit signed.

This makes easy the usage of integer and clarify signed and unsigned use.
With the previous version, signed and unsigned are used ones in place of
others, and sometimes the converter loose the sign. For example, divisions
are processed with "unsigned", if one entry is negative, the result is
wrong.

Note that the integer pattern matching and dotted version pattern matching
are already working with signed 64 bits integer values.

There is one user-visible change : the "uint()" and "sint()" sample fetch
functions which used to return a constant integer have been replaced with
a new more natural, unified "int()" function. These functions were only
introduced in the latest 1.6-dev2 so there's no impact on regular
deployments.

732eac41f4 MEDIUM: ssl: add sni support on the server lines
The new "sni" server directive takes a sample fetch expression and
uses its return value as a hostname sent as the TLS SNI extension.
A typical use case consists in forwarding the front connection's SNI
value to the server in a bridged HTTPS forwarder :

5fc7d7e8ce MINOR: Add sample fetch to detect Supported Elliptic Curves Extension
Clients that support ECC cipher suites SHOULD send the specified extension
within the SSL ClientHello message according to RFC4492, section 5.1. We
can use this extension to chain-proxy requests so that, on the same IP
address, a ECC compatible clients gets an EC certificate and a non-ECC
compatible client gets a regular RSA certificate. The main advantage of this
approach compared to the one presented by Dave Zhu on the mailing list
is that we can make it work with OpenSSL versions before 1.0.2.

Example:
frontend ssl-relay
        mode tcp
        bind 0.0.0.0:443
        use_backend ssl-ecc if { req.ssl_ec_ext 1 }
        default_backend ssl-rsa

backend ssl-ecc
        mode tcp
        server ecc unix@/var/run/haproxy_ssl_ecc.sock send-proxy-v2 check

backend ssl-rsa
        mode tcp
        server rsa unix@/var/run/haproxy_ssl_rsa.sock send-proxy-v2 check

listen  all-ssl
        bind unix@/var/run/haproxy_ssl_ecc.sock accept-proxy ssl crt /usr/local/haproxy/ecc.foo.com.pem user nobody
        bind unix@/var/run/haproxy_ssl_rsa.sock accept-proxy ssl crt /usr/local/haproxy/www.foo.com.pem user nobody

2fbcafc9ce MEDIUM: http: Add new 'set-src' option to http-request
This option enables overriding source IP address in a HTTP request. It is
useful when we want to set custom source IP (e.g. front proxy rewrites address,
but provides the correct one in headers) or we wan't to mask source IP address
for privacy or compliance.

It acts on any expression which produces correct IP address.

46175dd81d DOC: dns: fix chapters syntax
All chapters in the configuration documentation used to follow this syntax :
<chapter number>. <title>
-------------------------

The new chapters introduced to document the dns resolution didn't provide the
dot character after the chapter number, which breaks the parsing for the HTML
converter. Instead of adding new conditions in the converter, we can align the
chapters with this syntax.

It is possible to propagate entries of any data-types in stick-tables between
several haproxy instances over TCP connections in a multi-master fashion. Each
instance pushes its local updates and insertions to remote peers. The pushed
values overwrite remote ones without aggregation. Interrupted exchanges are
automatically detected and recovered from the last known point.

31af49d62b MEDIUM: ssl: Add options to forge SSL certificates
With this patch, it is possible to configure HAProxy to forge the SSL
certificate sent to a client using the SNI servername. We do it in the SNI
callback.

To enable this feature, you must pass following BIND options:

 * ca-sign-file <FILE> : This is the PEM file containing the CA certitifacte and
   the CA private key to create and sign server's certificates.

 * (optionally) ca-sign-pass <PASS>: This is the CA private key passphrase, if
   any.

 * generate-certificates: Enable the dynamic generation of certificates for a
   listener.

Because generating certificates is expensive, there is a LRU cache to store
them. Its size can be customized by setting the global parameter
'tune.ssl.ssl-ctx-cache-size'.

  deviceatlas-property-separator

First, the configuration keywords handling (only the log
level configuration part does not end the haproxy process
if it is wrongly set, it fallbacks to the default level).
Furthermore, init, deinit phases and the API lookup phase,
the da_haproxy function which is fed by the input provided
and set all necessary properties chosen via the configuration
to the output, separated by the separator.

Proxy sections does not support bind address as argument anymore.  Those
sections supports only an <id> argument.

The 'defaults' section didn't had any check on its arguments. It takes
an optional <name> argument.

'peers' section takes a <peersect> argument.

'userlist' section takes a <listname> argument.

51d861a44f MEDIUM: http: implement http-response redirect rules
Sometimes it's problematic not to have "http-response redirect" rules,
for example to perform a browser-based redirect based on certain server
conditions (eg: match of a header).

This patch adds "http-response redirect location <fmt>" which gives
enough flexibility for most imaginable operations. The connection to
the server is closed when this is performed so that we don't risk to
forward any pending data from the server.

Any pending response data are trimmed so that we don't risk to
forward anything pending to the client. It's harmless to also do that
for requests so we don't need to consider the direction.

Note that this patch removs an unused list initilisation, which seems
to be inherited from a copy/paste. It's harmless and does not need to
be backported.

726ab7145c MEDIUM: backend: Allow redispatch on retry intervals
For backend load balancing it sometimes makes sense to redispatch rather
than retrying against the same server. For example, when machines or routers
fail you may not want to waste time retrying against a dead server and
would instead prefer to immediately redispatch against other servers.

This patch allows backend sections to specify that they want to
redispatch on a particular interval. If the interval N is positive the
redispatch occurs on every Nth retry, and if the interval N is negative then
the redispatch occurs on the Nth retry prior to the last retry (-1 is the
default and maintains backwards compatibility). In low latency environments
tuning this setting can save a few hundred milliseconds when backends fail.
