This patch adds the support for the RFC2385 (Protection of BGP Sessions via
the + TCP MD5 Signature Option) for the listeners and the servers. The
feature is only available on Linux. Keywords are not exposed otherwise.
By setting "tcp-md5sig <password>" option on a bind line, TCP segments of
all connections instantiated from the listening socket will be signed with a
16-byte MD5 digest. The same option can be set on a server line to protect
outgoing connections to the corresponding server.
The primary use case for this option is to allow BGP to protect itself
against the introduction of spoofed TCP segments into the connection
stream. But it can be useful for any very long-lived TCP connections.
A reg-test was added and it will be executed only on linux. All other
targets are excluded.
Contrary to what the doc says, the jwt_verify converter only works with
a public key and not a full certificate for certificate based protocols
(everything but HMAC).
This patch should be backported up to 2.8.

As mentioned during the NUMA series development, the goal is to use
all available cores in the most efficient way by default, which
normally corresponds to "cpu-policy performance". The previous default
choice of "cpu-policy first-usable-node" was only meant to stay 100%
identical to before cpu-policy.
So let's switch the default cpu-policy to "performance" right now.
The doc was updated to reflect this.
Clarify that HAProxy duplicates crt-list entries for multi-cert bundles
which can create unexpected side-effects as only the very first
certificate after duplication is considered as default implicitly.
As mentioned in [1], the "dispatch" directive from haproxy 1.0 has long
outlived its original purpose and still suffers from a number of technical
limitations (no checks, no SSL, no idle connes etc) and still hinders some
internal evolutions. It's now time to mark it as deprecated, and to remove
it in 3.5 [2]. It was already recommended against in the documentation but
remained popular in raw TCP environments for being shorter to write.
The directive will now cause a warning to be emitted, suggesting an
alternate method involving "server". The warning can be shut using
"expose-deprecated-directives". The rare configs from 1.0 where
"dispatch" is combined with sticky servers using cookies will just
need to set these servers's weights to zero to prevent them from
being selected by the load balancing algorithm. All of this is
explained in the doc with examples.
Two reg tests were using this method, one purposely for this directive,
which now has expose-deprecated-directives, and another one to test the
behavior of idle connections, which was updated to use "server" and
extended to test both "http-reuse never" and "http-reuse always".

[2] https://github.com/haproxy/wiki/wiki/Breaking-changes
The explanations for the "option transparent" keyword were a bit scarce
regarding deprecation, so let's explain how to replace it with a server
line that does the same.
As discussed here [1], "transparent" (already deprecated) and
"option transparent" are horrible hacks which should really disappear
in favor of "server xxx 0.0.0.0" which doesn't rely on hackish code
path. This old feature is now deprecated in 3.3 and will disappear in
3.5, as indicated here [2]. A warning is emitted when used, explaining
how to proceed, and how to silence the warning using the global
"expose-deprecated-directives" if needed. The doc was updated to
reflect this new state.

This "renegotiate" option can be set on SSL backends to allow secure
renegotiation. It is mostly useful with SSL libraries that disable
secure regotiation by default (such as AWS-LC).
The "no-renegotiate" one can be used the other way around, to disable
secure renegotation that could be allowed by default.
Those two options can be set via "ssl-default-server-options" as well.
prefer-client-ciphers does not work exactly the same way when used with
a dual algorithm stack (ECDSA + RSA). This patch details its behavior.
This patch must be backported in every maintained version.
Problem was discovered in #2988.
There was already a check for this but there used to be an exception
that allowed duplicate server names only in case where their IDs were
explicit and different. This has been emitting a warning since 3.1 and
planned for removal in 3.3, so let's do it now. The doc was updated,
though it never mentioned this unicity constraint, so that was added.
Only the check for the exception was removed, the rest of the code
that is currently made to deal with duplicate server names was not
cleaned yet (e.g. the tree doesn't need to support dups anymore, and
this could be done at insertion time). This may be a subject for future
cleanups.
As warned since 3.1, it's no longer permitted to have a frontend and
a backend under the same name. This causes too many designation issues,
and causes trouble with stick-tables as well. Now each proxy name is
unique.
This commit only changes the check to return an error. Some code parts
currently exist to find the best candidates, these will be able to be
simplified as future cleanup patches. The doc was updated.
Add some notes which load-balancing algorithm can be considered as
deterministic or non-deterministic and add some examples for each type.
This was asked via mailing list to clarify the usage of
prefer-last-server option.
This can be backported to all stable versions.

- BUG/MINIR: h1: Fix doc of 'accept-unsafe-...-request' about URI parsing
The description of tests performed on the URI in H1 when
'accept-unsafe-violations-in-http-request' option is wrong. It states that
only characters below 32 and 127 are blocked when this option is set,
suggesting that otherwise, when it is not set, all invalid characters in the
URI, according to the RFC3986, are blocked.
But in fact, it is not true. By default all character below 32 and above 127
are blocked. And when 'accept-unsafe-violations-in-http-request' option is
set, characters above 127 (excluded) are accepted. But characters in
(33..126) are never checked, independently of this option.
This patch should fix the issue #2906. It should be backported as far as
3.0. For older versions, the docuementation could also be clarified because
this part is not really clear.
Note the request URI validation is still under discution because invalid
characters in (33.126) are never checked and some users request a stricter
parsing.

It is now possile to set a label on a bind line. All sockets attached to
this bind line inherits from this label. The idea is to be able to groud of
sockets. For now, there is no mechanism to create these groups, this must be
done by hand.
This is essentially in order to address the concerns expressed in
issue #2226 where it is mentioned that the moment they are called is
not clear enough. Admittedly, re-reading the paragraph doesn't make
it obvious on a quick read that they behave like functions. This patch
adds an extra paragraph that makes the parallel with programming
languages' boolean functions and explains the fact that they can be
multi-valued. Hoping this is clearer now.
Issue #2267 suggests that it's unclear what exactly the byte counts mean
(particularly when compression is involved). Let's clarify that the counts
are read on data input and that they also cover headers and a bit of
internal overhead.
As reported in issue #2195, cookie captures and header captures are no
longer the recommended way to proceed. Let's mention that this is the
legacy way and provide a few pointers to the recommended functions and
actions to use the modern methods.
As reported in issue #2327, the wording used in the section about quoting
can be read two ways due to the use of the two types of quotes to protect
each other quote. Better only use the quoting without mixing the two when
mentioning them.
Fix a bad example in the crt-store section. site1 does not use the "web"
crt-store but the global one.
Must be backported as far as 3.0 however the section was 3.12 in
previous version.
Currently there is "no-tls-tickets" that is also supported in the
ssl-default-bind-options directive, but there's no way to re-enable
them on a specific "bind" line. This patch simply provides the option
to re-enable them. Note that the flag is inverted because tickets are
enabled by default and the no-tls-ticket option sets the flag to
disable them.
Several users already reported that it would be nice to support
strict-sni in ssl-default-bind-options. However, in order to support
it, we also need an option to disable it.
This patch moves the setting of the option from the strict_sni field
to a flag in the ssl_options field so that it can be inherited from
the default bind options, and adds a new "no-strict-sni" directive to
allow to disable it on a specific "bind" line.
The test file "del_ssl_crt-list.vtc" which already tests both options
was updated to make use of the default option and the no- variant to
confirm everything continues to work.

- CLEANUP: cfgparse: alphabetically sort the global keywords
- MINOR: glitches: add global setting "tune.glitches.kill.cpu-usage"
It was mentioned during the development of glitches that it would be
nice to support not killing misbehaving connections below a certain
CPU usage so that poor implementations that routinely misbehave without
impact are not killed. This is now possible by setting a CPU usage
threshold under which we don't kill them via this parameter. It defaults
to zero so that we continue to kill them by default.
Tim reported in issue #2953 that "stick-table" and "table" were not
indexed as keywords. The issue was the indent level. Also let's make
sure to put a box around the "store" arguments as well.
From the documentation, this wasn't clear enough that shards should
be followed by one of the options number / by-thread / by-group.
Align it with existing options in documentation so that it becomes
more explicit.

Due to some historic mistakes that have spread to newly added sections,
a number of of recently added small sections found themselves described
under section 3 "global parameters" which is specific to "global" section
keywords. This is highly confusing, especially given that sections 3.1,
3.2, 3.3 and 3.10 directly start with keywords valid in the global section,
while others start with keywords that describe a new section.
Let's just create a new chapter "12. other sections" and move them all
there. 3.10 "HTTPclient tuning" however was moved to 3.4 as it's really
a definition of the global options assigned to the HTTP client. The
"programs" that are going away in 3.3 were moved at the end to avoid a
renumbering later.
Another nice benefit is that it moves a lot of text that was previously
keeping the global and proxies sections apart.
As suggested by Tim in issue #2953, stick-tables really deserve their own
section to explain the configuration. And peers have to move there as well
since they're totally dedicated to stick-tables.
Now we introduce a new section "Stick-tables and Peers", explaining the
concepts, and under which there is one subsection for stick-tables
configuration and one for the peers (which mostly keeps the existing
peers section).
Section 2 describes the config file format, variables naming etc, so
there's no reason why the address format used in this file should be
in a separate section, let's bring it into section 2 as well.
Most of the time, machines made of multiple CPU types use the same L3
for them, and grouping CPUs by frequencies to form groups doesn't bring
any value and on the opposite can impair the incoming connection balancing.
This choice of grouping by cluster was made in order to constitute a good
choice on homogenous machines as well, so better rely on the per-CCX
grouping than the per-cluster one in this case. This will create less
clusters on machines where it counts without affecting other ones.
It doesn't seem necessary to change anything for the "resource" policy
since it selects a single cluster.
This is similar to the previous change to the "performance" policy but
it applies to the "efficiency" one. Here we're changing the sorting
method to sort CPU clusters by average per-CPU capacity, and we evict
clusters whose per-CPU capacity is above 125% of the previous one.
Per-core capacity allows to detect discrepancies between CPU cores,
and to continue to focus on efficient ones as a priority.
Running the "performance" policy on highly heterogenous systems yields
bad choices when there are sufficiently more small than big cores,
and/or when there are multiple cluster types, because on such setups,
the higher the frequency, the lower the number of cores, despite small
differences in frequencies. In such cases, we quickly end up with
"performance" only choosing the small or the medium cores, which is
contrary to the original intent, which was to select performance cores.
This is what happens on boards like the Orion O6 for example where only
the 4 medium cores and 2 big cores are choosen, evicting the 2 biggest
cores and the 4 smallest ones.
Here we're changing the sorting method to sort CPU clusters by average
per-CPU capacity, and we evict clusters whose per-CPU capacity falls
below 80% of the previous one. Per-core capacity allows to detect
discrepancies between CPU cores, and to continue to focus on high
performance ones as a priority.
This cpu-policy will only consider CCX and not clusters. This makes
a difference on machines with heterogenous CPUs that generally share
the same L3 cache, where it's not desirable to create multiple groups
based on the CPU types, but instead create one with the different CPU
types. The variants "group-by-2/3/4-ccx" have also been added.
Let's also add some text explaining the difference between cluster
and CCX.
IPv6 connectivity might start off (e.g. network not fully up when
haproxy starts), so for features like resolvers, it would be nice to
periodically recheck.
With this change, instead of having the resolvers code rely on a variable
indicating connectivity, it will now call a function that will check for
how long a connectivity check hasn't been run, and will perform a new one
if needed. The age was set to 30s which seems reasonable considering that
the DNS will cache results anyway. There's no saving in spacing it more
since the syscall is very check (just a connect() without any packet being
emitted).
The variables remain exported so that we could present them in show info
or anywhere else.
This way, "dns-accept-family auto" will now stay up to date. Warning
though, it does perform some caching so even with a refreshed IPv6
connectivity, an older record may be returned anyway.
The automatic scheduler is useful but sometimes you don't want to use,
or schedule manually.
This patch adds an 'acme.scheduler' option in the global section, which
can be set to either 'auto' or 'off'. (auto is the default value)
This also change the ouput of the 'acme status' command so it does not
shows scheduled values. The state will be 'Stopped' instead of
'Scheduled'.
