6ade861305 REGTESTS: Fix proxy_protocol_tlv_validation
Remaining data after the PROXYv2 header now trigger a parsing error in the
H1 multiplexer Thus the required version for this test is now set to 2.4.

4137889911 REGTESTS: mark proxy_protocol_random_fail as broken
As indicated in issue #907 it very frequently fails on FreeBSD, and
looking at it, it's broken in multiple ways. It relies on log ordering
between two layers, the first one being allowed to support h2. Given
that on FreeBSD it usually ends up in timeouts, it's very likely that
for some reason one frontend logs before the other one or that curl
uses h2 instead of h1 there, and that the log instance waits forever
for its lines.

Usually it works fine when run locally though, so let's not remove it
and mark it as broken instead so that it can still be used when relevant.

9947f77a59 REGTEST: Add connection/proxy_protocol_send_unique_id_alpn
This reg-test checks that sending unique IDs via PPv2 works for servers
with the `alpn` option specified (issue #640). As a side effect it also
checks that PPv2 works with ALPN (issue #651).

It has been verified that the test fails without the following commits
applied and succeeds with them applied.

   1f9a4ecea BUG/MEDIUM: backend: set the connection owner to the session when using alpn.
   083fd42d5 BUG/MEDIUM: connection: Ignore PP2 unique ID for stream-less connections
   eb9ba3cb2 BUG/MINOR: connection: Always get the stream when available to send PP2 line

Without the first two commits HAProxy crashes during execution of the
test. Without the last commit the test will fail, because no unique ID
is received.

1d52c7b52b REGTEST: make the PROXY TLV validation depend on version 2.2
Regtest proxy_protocol_tlv_validation was added by commit 488ee7fb6e
("BUG/MAJOR: proxy_protocol: Properly validate TLV lengths") but it
relies on a trick involving http-after-response to append a header
after a 400-badreq response, which is not possible in earlier versions,
so make it depend on 2.2.

cf6e0c8a83 MEDIUM: proxy_protocol: Support sending unique IDs using PPv2
This patch adds the `unique-id` option to `proxy-v2-options`. If this
option is set a unique ID will be generated based on the `unique-id-format`
while sending the proxy protocol v2 header and stored as the unique id for
the first stream of the connection.

This feature is meant to be used in `tcp` mode. It works on HTTP mode, but
might result in inconsistent unique IDs for the first request on a keep-alive
connection, because the unique ID for the first stream is generated earlier
than the others.

Now that we can send unique IDs in `tcp` mode the `%ID` log variable is made
available in TCP mode.

488ee7fb6e BUG/MAJOR: proxy_protocol: Properly validate TLV lengths
This patch fixes PROXYv2 parsing when the payload of the TCP connection is
fused with the PROXYv2 header within a single recv() call.

Previously HAProxy ignored the PROXYv2 header length when attempting to
parse the TLV, possibly interpreting the first byte of the payload as a
TLV type.

This patch adds proper validation. It ensures that:

1. TLV parsing stops when the end of the PROXYv2 header is reached.
2. TLV lengths cannot exceed the PROXYv2 header length.
3. The PROXYv2 header ends together with the last TLV, not allowing for
   "stray bytes" to be ignored.

A reg-test was added to ensure proper behavior.

This patch tries to find the sweat spot between a small and easily
backportable one, and a cleaner one that's more easily adaptable to
older versions, hence why it merges the "if" and "while" blocks which
causes a reindent of the whole block. It should be used as-is for
versions 1.9 to 2.1, the block about PP2_TYPE_AUTHORITY should be
dropped for 2.0 and the block about CRC32C should be dropped for 1.8.

This bug was introduced when TLV parsing was added. This happened in commit
b3e54fe387. This commit was first released
with HAProxy 1.6-dev1.

A similar issue was fixed in commit 7209c204bd.

This patch must be backported to HAProxy 1.6+.

dc1a3bd999 REGTEST: replace LEVEL option by a more human readable one.
This patch replaces LEVEL variable by REGTESTS_TYPES variable which is more
mnemonic and human readable. It is uses as a filter to run the reg tests scripts
where a commented #REGTEST_TYPE may be defined to designate their types.
Running the following command:

    $ REGTESTS_TYPES=slow,default

will start all the reg tests where REGTEST_TYPE is defines as 'slow' or 'default'.
Note that 'default' is also the default value of REGTEST_TYPE when not specified
dedicated to run all the current h*.vtc files. When REGTESTS_TYPES is not specified
there is no filter at all. All the tests are run.

This patches also defines REGTEST_TYPE with 'slow' value for all the s*.vtc files,
'bug' value for al the b*.vtc files, 'broken' value for all the k*.vtc files.

8ae37d8a7b REGTEST: fix a spurious "nbthread 4" in the connection test
Commit 26f6ae12c ("MAJOR: config: disable support for nbproc and nbthread
in parallel") revealed that there was accidently nbproc+nbthread in this
test while nbproc is the one expected. This likely is a leftover from a
previous attempt at reproducing the issue.

d3ff20f0ae REGTEST/MINOR: compatibility: use unix@ instead of abns@ sockets
Changes the /reg-tests/connection/b00000.vtc test to use unix@ instead of abns@ sockets.
This to allow the test to complete on other operating systems like FreeBSD that do not have 'namespaces'.
