44c67a08dd MINOR: tcp: add new bind option "tcp-ss" to instruct the kernel to save the SYN
This option enables TCP_SAVE_SYN on the listening socket, which will
cause the kernel to try to save a copy of the SYN packet header (L2,
IP and TCP are supported). This can permit to check the source MAC
address of a client, or find certain TCP options such as a source
address encapsulated using RFC7974. It could also be used as an
alternate approach to retrieving the source and destination addresses
and ports. For now setting the option is enabled, but sample fetch
functions and converters will be needed to extract info.

b562602044 MEDIUM: cfgparse: acknowledge that proxy ID auto numbering starts at 2
Each frontend/backend/listen proxies is assigned an unique ID. It can
either be set explicitely via 'id' keyword, or automatically assigned on
post parsing depending on the available values.

It was expected that the first automatically assigned value would start
at '1'. However, due to a legacy bug this is not the case as this value
is always skipped. Thus, automatically assigned proxies always start at
'2' or more.

To avoid breaking the current existing state, this situation is now
acknowledged with the current patch. The code is rewritten with an
explicit warning to ensure that this won't be fixed without knowing the
current status. A new regtest also ensures this.

5904f8279b MINOR: mux-h1: perform a graceful close at 75% glitches threshold
This avoids hitting the hard wall for connections with non-compliant
peers that are accumulating errors. We recycle the connection early
enough to permit to reset the counter. Example below with a threshold
set to 100:

Before, 1% errors:
  $ h1load -H "Host : blah" -c 1 -n 10000000 0:4445
  #     time conns tot_conn  tot_req      tot_bytes    err  cps  rps  bps   ttfb

After, no more errors:

05b457002b MEDIUM: mux-h1: implement basic glitches support
We now count glitches for each parsing error, including those that
have been accepted via accept-unsafe-violations-*. Front and back
are considered and the connection gets killed on error once if the
threshold is reached or passed and the CPU usage is beyond the
configured limit (0 by default). This was tested with:

   curl -ivH "host : blah" 0:4445{,,,,,,,,,}

which sends 10 requests to a configuration having a threshold of 5.
The global keywords are named similarly to H2 and quic:

     tune.h1.be.glitches-threshold xxxx
     tune.h1.fe.glitches-threshold xxxx

The glitches count of each connection is also reported when non-null
in the connection dumps (e.g. "show fd").

0901f60cef MINOR: mux-h2: perform a graceful close at 75% glitches threshold
This avoids hitting the hard wall for connections with non-compliant
peers that would be accumulating errors over long connections. We now
permit to recycle the connection early enough to reset the connection
counter.

This was tested artificially by adding this to h2c_frt_handle_headers():

  h2c_report_glitch(h2c, 1, "new stream");

or this to h2_detach():

  h2c_report_glitch(h2c, 1, "detaching");

and injecting using h2load -c 1 -n 1000 0:4445 on a config featuring
tune.h2.fe.glitches-threshold 1000:

The failures are due to h2load not supporting reconnection.

bd92f34f02 DOC: config: fix number of values for "cpu-affinity"
It said "accepts 2 values" then goes on enumerating 5 since more were

8aef5bec1e MEDIUM: cpu-topo: Add the "per-ccx" cpu_affinity
Add a new cpu-affinity keyword, "per-ccx".
If used, each thread will be bound to all the hardware threads available
in one CCX of the threads group.

c524b181a2 MEDIUM: cpu-topo: Add the "per-thread" cpu_affinity
Add a new cpu-affinity keyword, "per-thread".
If used, each thread will be bound to only one hardware thread of the
thread group.
If used in conjonction with the "threads-per-core 1" cpu_policy, then
each thread will be bound on a different core.

7e22d9c484 MEDIUM: cpu-topo: Add a new "max-threads-per-group" global keyword
Add a new global keyword, max-threads-per-group. It sets the maximum number of
threads a thread group can contain. Unless the number of thread groups
is fixed with "thread-groups", haproxy will just create more thread
groups as needed.
The default and maximum value is 64.

Olivier Houchard
3865f6c5c6 MEDIUM: cpu-topo: Add a "cpu-affinity" option
Add a new global option, "cpu-affinity", which controls how threads are
bound.
It currently accepts three values, "per-core", which will bind one thread to
each hardware thread of a given core, and "per-group" which will use all
the available hardware threads of the thread group, and "auto", the
default, which will use "per-group", unless "threads-per-core 1" has
been specified in cpu_policy, in which case it will use per-core.

Olivier Houchard
3671652bc9 MEDIUM: cpu-topo: Add a "threads-per-core" keyword to cpu-policy
Add a new, optional key-word to "cpu-policy", "threads-per-core".
It takes one argument, "1" or "auto". If "1" is used, then only one
thread per core will be created, no matter how many hardware thread each
core has. If "auto" is used, then one thread will be created per
hardware thread, as is the case by default.

for example: cpu-policy performance threads-per-core 1

47dff5be52 MINOR: quic: implement cc-algo server keyword
Extend QUIC server configuration so that congestion algorithm and
maximum window size can be set on the server line. This can be achieved
using quic-cc-algo keyword with a syntax similar to a bind line.

This should be backported up to 3.3 as this feature is considered as
necessary for full QUIC backend support. Note that this relies on the
serie of previous commits which should be picked first.

49e6fca51b MINOR: quic: use separate global quic_conns FE/BE lists
Each quic_conn instance is stored in a global list. Its purpose is to be
able to loop over all known connections during "show quic".

Split this into two separate lists for frontend and backend usage.
Another change is that closing backend connections do not move into
quic_conns_clo list. They remain instead in their original list. The
objective of this patch is to reduce the contention between the two
sides.

Note that this prevents backend connections to be listed in "show quic"
now. This will be adjusted in a future patch.

0367227375 MEDIUM: mworker: set the mworker-max-reloads to 50
There was no mworker-max-reload value by default, it was set to INT_MAX
so this was impossible to reach.

The default value is now 50, which is still high, but no workers should
undergo that much reloads. Meaning that a worker will be killed with
SIGTERM if it reach this much reloads.

ef206d441c MINOR: check: ensure QUIC checks configuration coherency
QUIC is now supported on the backend side, thus it is possible to use it
with server checks. However, checks configuration can be quite
extensive, differing greatly from the server settings.

This patch ensures that QUIC checks are always performed under a
controlled context. Objectives are to avoid any crashes and ensure that
there is no suprise for users in respect to the configuration.

The first part of this patch ensures that QUIC checks can only be
activated on QUIC servers. Indeed, QUIC requires dedicated
initialization steps prior to its usage.

The other part of this patch disables QUIC usage when one or multiple
specific check connection settings are specified in the configuration,
diverging from the server settings. This is the simplest solution for
now and ensure that there is no hidden behavior to users. This means
that it's currently impossible to perform QUIC checks if other endpoints
that the server itself. However for now there is no real use-case for
this scenario.

Along with these changes, check-proto documentation is updated to
clarify QUIC checks behavior.

AWSLC_API_VERSION constant.

that help to check the AWS-LC API.

8415254cea MINOR: check: clarify check-reuse-pool interaction with reuse policy

5d021c028e BUG/MINOR: check: only try connection reuse for http-check rulesets
In 3.2, a new server keyword "check-reuse-pool" has been introduced. It
allows to reuse a connection for a new check, instead of always
initializing a new one. This is only performed if the check does not
rely on specific connection parameters differing from the server.

This patch further restricts reuse for checks only when an HTTP ruleset
is used at the backend level. Indeed, reusing a connection outside of
HTTP is an undefined behavior. The impact of this bug is unknown and
depends on the proxy/server configuration. In the case of an HTTP
backend with non-HTTP checks, check-reuse-pool would probably cause a
drop in reuse rate.

Along this change, implement a new diagnostic warning on servers to
report that check-reuse-pool cannot apply due to an incompatible check
type.

This must be backported up to 3.2.

1d46c08689 MINOR: ssl/sample: expose ssl_*c_curve for AWS-LC
The underlying SSL_get_negotiated_group function has been backported
into AWS-LC [1], so expose the feature for users of this TLS stack
as well. Note that even though it was actually added in AWS-LC 1.56.0,
we require AWSLC_API_VERSION >= 35 which was released in AWS-LC 1.57.0,
because API version wasn't incremented after this change. As the delta
is one minor version (less than two weeks), I consider this acceptable
to avoid relying on a proxy constant like TLSEXT_nid_unknown which
might be removed at some point.

c6f68901cc BUG/MINOR: config: Limit "tune.maxpollevents" parameter to 1000000
"tune.maxpollevents" global parameter was not limited. It was possible to
set any integer value. But this value is used to allocate the array of
events used by epoll. With a huge value, it seems the allocation silently
fail, making haproxy totally unresponsive.

So let's to limit its value to 1 million. It is pretty high and it should
not be an issue to forbid greater values. The documentation was updated
accordingly.

This patch could be backported to all stable branches.
