When using the httpclient, one could be bothered with it returning
after a very long time when failing. By default the httpclient has a
retries of 3 and a timeout connect of 5s, which can results in pause of
20s upon failure.
This patch allows the user to configure the "timeout connect" of the
httpclient so it could reduce the time to return an error.
This patch helps fixing part of the issue #2269.
Could be backported in 2.7 if needed.

The progressive adoption of OpenSSL 3 and its abysmal handshake
performance has started to reveal situations where it simply isn't
possible anymore to succesfully run health checks on many servers,
because between the moment all the checks are started and the moment
the handshake finally completes, the timeout has expired!
This also has consequences on production traffic which gets
significantly delayed as well, all that for lots of checks. While it's
possible to increase the check delays, it doesn't solve everything as
checks still take a huge amount of time to converge in such conditions.
Here we take a different approach by permitting to enforce the maximum
concurrent checks per thread limitation and implementing an ordered
queue. Thanks to this, if a thread about to start a check has reached
its limit, it will add the check at the end of a queue and it will be
processed once another check is finished. This proves to be extremely
efficient, with all checks completing in a reasonable amount of time
and not being disturbed by the rest of the traffic from other checks.
They're just cycling slower, but at the speed the machine can handle.
One must understand however that if some complex checks perform multiple
exchanges, they will take a check slot for all the required duration.
This is why the limit is not enforced by default.
Tests on SSL show that a limit of 5-50 checks per thread on local
servers gives excellent results already, so that could be a good starting
point.
When the current check is overloaded (more running checks than the
configured limit), we'll try more aggressively to find another thread.
Instead of just opportunistically looking for one half as loaded, now if
the current thread has more than 1% more active checks than another one,
or has more than a configured limit of concurrent running checks, it will
search for a more suitable thread among 3 other random ones in order to
migrate the check there. The number of migrations remains very low (~1%)
and the checks load very fair across all threads (~1% as well). The new
parameter is called tune.max-checks-per-thread.
Based on the new, generic allocation infrastructure, a new sample
fetch fc_pp_tlv is introduced. It is an abstraction for existing
PPv2 TLV sample fetches. It takes any valid TLV ID as argument and
returns the value as a string, similar to fc_pp_authority and
fc_pp_unique_id.
For a while there has been the constraint of having to run as root for
transparent proxying, and we're starting to see some cases where QUIC is
not running in socket-per-connection mode due to the missing capability
that would be needed to bind a privileged port. It's not realistic to
ask all QUIC users on port 443 to run as root, so instead let's provide
a basic support for capabilities at least on linux. The ones currently
supported are cap_net_raw, cap_net_admin and cap_net_bind_service. The
mechanism was made OS-specific with a dedicated file because it really
is. It can be easily refined later for other OSes if needed.
A new keyword "setcaps" is added to the global section, to enumerate the
capabilities that must be kept when switching from root to non-root. This
is ignored in other situations though. HAProxy has to be built with
USE_LINUX_CAP=1 for this to be supported, which is enabled by default
for linux-glibc, linux-glibc-legacy and linux-musl.
A good way to test this is to start haproxy with such a config:
global
uid 1000
setcap cap_net_bind_service
frontend test
mode http
timeout client 3s
bind quic4@:443 ssl crt rsa+dh2048.pem allow-0rtt
and run it under "sudo strace -e trace=bind,setuid", then connecting
there from an H3 client. The bind() syscall must succeed despite the
user id having been switched.
This option defaults to "connection" but is also dependent on the user
being allowed to bind the specified port. Since QUIC can easily run on
non-privileged ports, usually this is not a problem, but if bound to port
443 it will usually fail. Let's mention this.

The be_name and be_id fetches contain data related to the current

no backend is used due to a local response or backend selection
failure, these fetches retain details of the current frontend.
This patch enhances the clarity of the values provided by these
fetches.

"converter" was used in place of "action" as a result of a copy-paste
error probably.
Also, rephrasing the "actions" keyword explanation to prevent confusion
between action name (which is the name of new action about to be created)
and action facilities where we want to expose the new action.
This could be backported to every stable versions.
Since f034139bc0 ("MINOR: lua: Allow reading "proc." scoped vars from
LUA core."), a new Sphinx warning is emitted when generating the lua doc:
"WARNING: Field list ends without a blank line; unexpected unindent."
This is due to a missing space after the line break continuation, sphinx
parser is very restrictive unfortunately!
Suppressing the warning and fixing the html output at the same time by
adding the missing space.
Implement parsing for "rev@" addresses on bind line. On config parsing,
server name is stored on the bind_conf.
Several new callbacks are defined on reverse_connect protocol to
complete parsing. listen callback is used to retrieve the server
instance from the bind_conf server name. If found, the server instance
is stored on the receiver. Checks are implemented to ensure HTTP/2
protocol only is used by the server.
Add an optional argument 'name' for attach-srv rule. This contains an
expression which will be used as an identifier inside the server idle
pool after reversal. To match this connection for a future transfer
through the server, the SNI server parameter must match this name. If no
name is defined, match will only occur with an empty SNI value.
For the moment, only the parsing step is implemented. An extra check is
added to ensure that the reverse server uses SSL with a SNI. Indeed, if
name is defined but server does not uses a SNI, connections will never
be selected on reused after reversal due to a hash mismatch.
Create a new tcp-request session rule 'attach-srv'.
The parsing handler is used to extract the server targetted with the
notation 'backend/server'. The server instance is stored in the act_rule
instance under the new union variant 'attach_srv'.
Extra checks are implemented in parsing to ensure attach-srv is only
used for proxy in HTTP mode and with listeners/server with no explicit
protocol reference or HTTP/2 only.
The action handler itself is really simple. It assigns the stored server
instance to the 'reverse' member of the connection instance. It will be
used in a future patch to implement passive reverse-connect.
Implement reverse-connect server. This server type cannot instantiate
its own connection on transfer. Instead, it can only reuse connection
from its idle pool. These connections will be populated using the future
'tcp-request session attach-srv' rule.
A reverse-connect has no address. Instead, it uses a new custom server
notation with '@' character prefix. For the moment, only '@reverse' is
defined. An extra check is implemented to ensure server is used in a
HTTP proxy.
Only sc-inc-gpc and sc-set-gpt do exist. The mix-up sc-inc-gpt crept in
in 71d189219 (DOC: config: Rework and uniformize how TCP/HTTP rules are
documented, 2021-10-14) and got copied in a92480462 (MINOR: http-rules:

mentions the fragment as well.
Implement 4 new fetches:
- ms_ltime
- ms_utime
- us_ltime
- us_utime
Which are the same as ltime and utime but with milliseconds and
microseconds input.
The converters also suports the %N conversion specifier like in date(1).
Unfortunately since %N is not supported by strftime, the format string
is parsed twice, once manually to replace %N, and once by strftime.
Implement %[accept_date] which returns the same as %Ts log-format tag.
Implement %[request_date] which is a timestamp for %tr.
accept_date and request_date take an faculative unit argument which can
be 's', 'ms' or 'us'.
The goal is to be able to convert these 2 timestamps to HAProxy date
format like its done with %T, %tr, %trg etc

Fixes: #2212
Signed-off-by: Daan van Gorkum <djvg@djvg.net>
Adds a new sample fetch method to get the curve name used in the
key agreement to enable better observability. In OpenSSLv3, the function
`SSL_get_negotiated_group` returns the NID of the curve and from the NID,
we get the curve name by passing the NID to OBJ_nid2sn. This was not
available in v1.1.1. SSL_get_curve_name(), which returns the curve name
directly was merged into OpenSSL master branch last week but will be available
only in its next release.
A typo in the "fc_src" description was fixed. This sample returns the
original source IP address and not the destination one.
This patch should be backported as far as 2.6.
As the example/lua/mailers.lua script does its best to mimic the c-mailer
implementation, it should support the "timeout mail" directive as well.
This could be backported in 2.8.
The current limitation of the 'ocsp-update' option and the fact that it
can only be used in crt-lists was puzzling for some people so the doc
was amended to emphasize this specificity. A configuration extract was
added as well.
A few troubleshooting clues were added as well.
Must be backported in 2.8.
This patch fixes a misalignment in the 'ocsp-update' option description
and it splits the example log lines for readability.
Must be backported in 2.8.

This patch introduces the "client-sigalgs" keyword for the server line,
which allows to configure the list of server signature algorithms
negociated during the handshake. Also available as
"ssl-default-server-client-sigalgs" in the global section.

It appears that dconv dislikes the "see also" part being on the same line as
the regular paragraph. The beginning of the line does not show up in the
rendered version.
Attempt to fix this by inserting an additional newline which is consistent with
other options.
Complementary fix to ac456ab ("DOC: config: fix rfc7239 converter examples")
since somehow I managed to overlook one example..
This needs to be backported in 2.8 with ac456ab.
To prevent bogus matches, var() does not default to string type anymore
since 44c5ff6 ("MEDIUM: vars: make the var() sample fetch function really
return type ANY).
Thanks to the above fix, haproxy now returns an error if var() is used
within an ACL or IF condition and the matching type is not explicitly
set.
However, the documentation was not updated to reflect this change.
This partially fixes GH #2087 and must be backported up to 2.6.
