The new 'close-spread-time' global option can be used to spread idle and
active HTTP connction closing after a SIGUSR1 signal is received. This
allows to limit bursts of reconnections when too many idle connections
are closed at once. Indeed, without this new mechanism, in case of
soft-stop, all the idle connections would be closed at once (after the
grace period is over), and all active HTTP connections would be closed
by appending a "Connection: close" header to the next response that goes
over it (or via a GOAWAY frame in case of HTTP2).
This patch adds the support of this new option for HTTP as well as HTTP2
connections. It works differently on active and idle connections.
On active connections, instead of sending systematically the GOAWAY
frame or adding the 'Connection: close' header like before once the
soft-stop has started, a random based on the remainder of the close
window is calculated, and depending on its result we could decide to
keep the connection alive. The random will be recalculated for any
subsequent request/response on this connection so the GOAWAY will still
end up being sent, but we might wait a few more round trips. This will
ensure that goaways are distributed along a longer time window than
before.
On idle connections, a random factor is used when determining the expire
field of the connection's task, which should naturally spread connection
closings on the time window (see h2c_update_timeout).
This feature request was described in GitHub issue #1614.
This patch should be backported to 2.5. It depends on "BUG/MEDIUM:
mux-h2: make use of http-request and keep-alive timeouts" which
refactorized the timeout management of HTTP2 connections.
This new converter is similar to the concat converter and can be used to
build new variables made of a succession of other variables but the main
difference is that it does the checks if adding a delimiter makes sense as
wouldn't be the case if e.g the current input sample is empty. That
situation would require 2 separate rules using concat converter where the
first rule would have to check if the current sample string is empty before
adding a delimiter. This resolves GitHub Issue #1621.
Reverts 75df9d7a7 ("DOC: explain HTTP2 timeout behavior") since H2
connections now respect "timeout http-keep-alive".
If commit 15a4733d5d ("BUG/MEDIUM: mux-h2: make use of http-request
and keep-alive timeouts") is backported, this DOC change needs to
be backported along with it.

- MEDIUM: server: remove experimental-mode for dynamic servers
- BUG/MINOR: buffer: fix debugging condition in b_peek_varint()
For server checks, SSL and PROXY is automatically inherited from the
server settings if no specific check port is specified. Change this
behavior for dynamic servers : explicit "check-ssl"/"check-send-proxy"
are required for them.
Without this change, it is impossible to add a dynamic server with
SSL/PROXY settings and checks without, if the check port is not
explicit. This is because "no-check-ssl"/"no-check-send-proxy" keywords
are not available for dynamic servers.
This change respects the principle that dynamic servers on the CLI
should not reuse the same shortcuts used during the config file parsing.
Mostly because we expect this feature to be manipulated by automated
tools, contrary to the config file which should aim to be the shortest
possible for human readability.
Update the documentation of the "check" keyword to reflect this change.
These two sample fetch methods report respectively the file name and the
line number where was located the last rule that was final. This is aimed
at being used on log-format lines to help admins figure what rule in the
configuration gave a final verdict, and help understand the condition
that led to the action.
For example, it's now possible to log the last matched rule by adding
this to the log-format:
... lr=%[last_rule_file]:%[last_rule_line]
A regtest is provided to test various combinations of final rules, some
even on top of each other from different rulesets.
The distcc* sample fetch methods were surprisingly located within the
"internal state" section, while they in fact depend on L6 contents.
This can be backported to all versions where they appear.
Some users with very large numbers of connections have been facing
extremely long malloc_trim() calls on reload that managed to trigger
the watchdog! That's a bit counter-productive. It's even possible
that some implementations are not perfectly reliable or that their
trimming time grows quadratically with the memory used. Instead of
constantly trying to work around these issues, let's offer an option
to disable this mechanism, since nobody had been complaining in the
past, and this was only meant to be an improvement.
This should be backported to 2.4 where trimming on reload started to
appear.

Avoid closing idle connections if a soft stop is in progress.
By default, idle connections will be closed during a soft stop. In some
environments, a client talking to the proxy may have prepared some idle
connections in order to send requests later. If there is no proper retry
on write errors, this can result in errors while haproxy is reloading.
Even though a proper implementation should retry on connection/write
errors, this option was introduced to support back compat with haproxy <
v2.4. Indeed before v2.4, we were waiting for a last request to be able
to add a "connection: close" header and advice the client to close the
connection.
In a real life example, this behavior was seen in AWS using the ALB in
front of a haproxy. The end result was ALB sending 502 during haproxy
reloads.
This patch was tested on haproxy v2.4, with a regular reload on the
process, and a constant trend of requests coming in. Before the patch,
we see regular 502 returned to the client; when activating the option,
the 502 disappear.
This patch should help fixing github issue #1506.
In order to unblock some v2.3 to v2.4 migraton, this patch should be
backported up to v2.4 branch.

The set-var converter as well as the http and tcp set-var actions can
now be given multiple conditions that need to all be true for the
variable's contents to actually be changed. Those conditions can concern
the variable as well as the input contents and can also work by
comparing the variable and the input values.
numa_detect_topology() is always define now if USE_CPU_AFFINITY is
activated. For the moment, only on Linux an actual implementation is
provided. For other platforms, it always return 0.
This change has been made to easily add implementation of NUMA detection
for other platforms. The phrasing of the documentation has also been
edited to removed the mention of Linux-only on numa-cpu-mapping
configuration option.
In commit 6f7497616 ("MEDIUM: connection: rename fc_conn_err and
bc_conn_err to fc_err and bc_err"), fc_conn_err became fc_err, so
update this example.
It is now possible to perform captures on the response when
http-after-response rules are evaluated. It may be handy to capture headers
from responses generated by HAProxy.
This patch is trivial, it may be backported if necessary.
With the master worker, the seamless reload was still requiring an
external stats socket to the previous process, which is a pain to
configure.
This patch implements a way to use the internal socketpair between the
master and the workers to transfer the sockets during the reload.
This way, the master will always try to transfer the socket, even
without any configuration.
The master will still reload with the -x argument, followed by the
sockpair@ syntax. ( ex -x sockpair@4 ). Which use the FD of internal CLI
to the worker.
Released version 2.5.0 with the following main changes :
- BUILD: SSL: add quictls build to scripts/build-ssl.sh
- BUILD: SSL: add QUICTLS to build matrix

Sometimes it is really useful to be able to specify a default value for
an optional environment variable, like the ${name-value} construct in
shell. In fact we're really missing this for a number of settings in
reg tests, starting with timeouts.
This commit simply adds support for the common syntax above. Other
common forms like '+' to replace existing variables, or ':-' and ':+'
to act on empty variables, were not implemented at this stage, as they
are less commonly needed.

TCP/HTTP allow actions stop rules evaluation of the current section
only. Only the http-response description was accurate on this
point. Thus, the documentation is now explicit on this point for all
other concerned rulesets.
This patch may be backported, to all supported versions for tcp-request
and http-request documentation, and as far as 2.2 for http-after-response
documentation.
In ssl_fc_unique_id decription, threre is a reference to the wrong sample
fetch. ssl_bc_unique_id is used instead of ssl_fc_unique_id.
This patch should fix the issue #1449. It may be backported to all
supportted versions.

- MEDIUM: log: add the client's SNI to the default HTTPS log format
- DOC: config: add an example of reasonably complete error-log-format
- DOC: config: move error-log-format before custom log format
All default formats were described before the custom one, except this
one. Better place them all together before the custom log format. This
only swaps and renumbers the sections.
During a troublehooting it came obvious that the SNI always ought to
be logged on httpslog, as it explains errors caused by selection of
the default certificate (or failure to do so in case of strict-sni).
This expectation was also confirmed on the mailing list.
Since the field may be empty it appeared important not to leave an
empty string in the current format, so it was decided to place the
field before a '/' preceding the SSL version and ciphers, so that
in the worst case a missing field leads to a field looking like
"/TLSv1.2/AES...", though usually a missing element still results
in a "-" in logs.
This will change the log format for users who already deployed the
2.5-dev versions (hence the medium level) but no released version
was using this format yet so there's no harm for stable deployments.
The reg-test was updated to check for "-" there since we don't send
SNI in reg-tests.

I'm always having a very hard time finding the log-format definition of
httplog, because it's not in the httplog description, and looking for
"httplog" doesn't yield the custom log formats section.
It would make more sense to write these log-formats into their respective
sections where they will be easier to find. That's what this commit does.
Commit 3d2093af9 ("MINOR: connection: Add a connection error code sample
fetch") added these convenient sample-fetch functions but it appears that
due to a misunderstanding the redundant "conn" part was kept in their
name, causing confusion, since "fc" already stands for "front connection".
Let's simply call them "fc_err" and "bc_err" to match all other related
ones before they appear in a final release. The VTC they appeared in were
also updated, and the alpha sort in the keywords table updated.

This directive is documented as being ignored if set in a defaults
section. But it is only mentionned in a small note in the configuration
manual. Thus, now, a warning is emitted. To do so, the errors handling in
parse_compression_options() function was slightly changed.
In addition, this directive is now documented apart from the other
compression directives. This way, it is clearly visible that it must not be
used in a defaults section.
Implement parsing for the server keyword 'ws'. This is used to configure
the mode of selection for websocket protocol. The configuration
documentation has been updated.
A new regtest has been created to test the proper behavior of the
keyword.

Session struct is already allocated when "tcp-request connection" rules
are evaluated so session-scoped variables turned out easy to support.
This resolves github issue #1408.
Because source and destination address of the client connection are now
updated at the appropriated level (connection, session or stream), original
info about the client connection are preserved. src/src_port/src_is_local
and dst/dst_port/dst_is_local return current info about the client
connection. It is the info at the highest available level. Most of time, the
stream. Any tcp/http rules may alter this info.
To get original info, "fc_" prefix must be added. For instance
"fc_src". Here, only "tcp-request connection" rules may alter source and
destination address/port.
This patch was reverted because it was inconsitent to change connection
addresses at stream level. Especially in HTTP because all requests was
affected by this change and not only the current one. In HTTP/2, it was
worse. Several streams was able to change the connection addresses at the
same time.
It is no longer an issue, thanks to recent changes. With multi-level client
source and destination addresses, it is possible to limit the change to the
current request. Thus this patch can be reintroduced.
If it possible to set source IP/Port from "tcp-request connection",
"tcp-request session" and "http-request" rules but not from "tcp-request
content" rules. There is no reason for this limitation and it may be a
problem for anyone wanting to call a lua fetch to dynamically set source
IP/Port from a TCP proxy. Indeed, to call a lua fetch, we must have a
stream. And there is no stream when "tcp-request connection/session" rules
are evaluated.
Thanks to this patch, "set-src" and "set-src-port" action are now supported
by "tcp_request content" rules.
This patch is related to the issue #1303.

In order for all the error return values to be distributed on the same
side (instead of surrounding the success error code), the return values
for errors other than a simple verification failure are switched to
negative values. This way the result of the jwt_verify converter can be
compared strictly to 1 as well relative to 0 (any <= 0 return value is
an error).
The documentation was also modified to discourage conversion of the
return value into a boolean (which would definitely not work).

Now all these rules are documented using the same structure. First there is
a general description with the list of all supported actions. Then all
actions are described in details. Thus, it is easy to have a quick list of
all supported actions and this avoids to have a huge description with all
info about these actions. In addition, when it is possible, we make a
reference to already documented parts.
Documentation of each directive that can now be used in defaults section was
updated to explain how it works. A special mark was added to specify when a
keyword is supported by defaults sections with a name but not anonymous
ones. In this case an exclamation mark is added.
It is now possible to designate the defaults section to use by adding a name
of the corresponding defaults section and referencing it in the desired
proxy section. However, this introduces an ambiguity. This named defaults
section may still be implicitly used by other proxies if it is the last one
defined. In this case for instance:
default common
...
default frt from common
...
default bck from common
...
frontend fe from frt
...
backend be from bck
...
listen stats
...
Here, it is not really obvious the last section will use the 'bck' defaults
section. And it is probably not the expected behaviour. To help users to
properly configure their haproxy, a warning is now emitted if a defaults
section is explicitly AND implicitly used. The configuration manual was
updated accordingly.
Because this patch adds a warning, it should probably not be backported to
2.4. However, if is is backported, it depends on commit "MINOR: proxy:
Introduce proxy flags to replace disabled bitfield".
In multi-threaded mode, on operating systems supporting multiple listeners on
the same IP:port, this will automatically create this number of multiple
identical listeners for the same line, all bound to a fair share of the number
of the threads attached to this listener. This can sometimes be useful when
using very large thread counts where the in-kernel locking on a single socket
starts to cause a significant overhead. In this case the incoming traffic is
distributed over multiple sockets and the contention is reduced. Note that
doing this can easily increase the CPU usage by making more threads work a
little bit.
If the number of shards is higher than the number of available threads, it
will automatically be trimmed to the number of threads. A special value
"by-thread" will automatically assign one shard per thread.
This new converter takes a JSON Web Token, an algorithm (among the ones
specified for JWS tokens in RFC 7518) and a public key or a secret, and
it returns a verdict about the signature contained in the token. It does
not simply return a boolean because some specific error cases cas be
specified by returning an integer instead, such as unmanaged algorithms
or invalid tokens. This enables to distinguich malformed tokens from
tampered ones, that would be valid format-wise but would have a bad
signature.
This converter does not perform a full JWT validation as decribed in
section 7.2 of RFC 7519. For instance it does not ensure that the header
and payload parts of the token are completely valid JSON objects because
it would need a complete JSON parser. It only focuses on the signature
and checks that it matches the token's contents.
Those converters allow to extract a JSON value out of a JSON Web Token's
header part or payload part (the two first dot-separated base64url
encoded parts of a JWS in the Compact Serialization format).
They act as a json_query call on the corresponding decoded subpart when
given parameters, and they return the decoded JSON subpart when no
parameter is given.
This fetch can be used to retrieve the data contained in an HTTP
Authorization header when the Bearer scheme is used. This is used when
transmitting JSON Web Tokens for instance.

- MINOR: threads: add a new function to resolve config groups and masks
- MEDIUM: config: resolve relative threads on bind lines to absolute ones
- MEDIUM: stick-table: never learn the "conn_cur" value from peers
There have been a large number of issues reported with conn_cur
synchronization because the concept is wrong. In an active-passive
setup, pushing the local connections count from the active node to
the passive one will result in the passive node to have a higher
counter than the real number of connections. Due to this, after a
switchover, it will never be able to close enough connections to
go down to zero. The same commonly happens on reloads since the new
process preloads its values from the old process, and if no connection
happens for a key after the value is learned, it is impossible to reset
the previous ones. In active-active setups it's a bit different, as the
number of connections reflects the number on the peer that pushed last.
This patch solves this by marking the "conn_cur" local and preventing
it from being learned from peers. It is still pushed, however, so that
any monitoring system that collects values from the peers will still
see it.
The patch is tiny and trivially backportable. While a change of behavior
in stable branches is never welcome, it remains possible to fix issues
if reports become frequent.
This extends the "thread" statement of bind lines to support an optional
thread group number. When unspecified (0) it's an absolute thread range,
and when specified it's one relative to the thread group. Masks are still
used so no more than 64 threads may be specified at once, and a single
group is possible. The directive is not used for now.
This registers a mapping of threads to groups by enumerating for each thread
what group it belongs to, and marking the group as assigned. It takes care of
checking for redefinitions, overlaps, and holes. It supports both individual
numbers and ranges. The thread group is referenced from the thread config.
Add a more precise description on how backslash escaping is different
than the top-level parser, and give examples of how to handle single
quotes inside arguments.
The ssl_bc_hsk_err sample fetch will need to raise more errors than only
handshake related ones hence its renaming to a more generic ssl_bc_err.
This patch is required because some handshake failures that should have
been caught by this fetch (verify error on the server side for instance)
were missed. This is caused by a change in TLS1.3 in which the
'Finished' state on the client is reached before its certificate is sent
(and verified) on the server side (see the "Protocol Overview" part of
RFC 8446).
This means that the SSL_do_handshake call is finished long before the
server can verify and potentially reject the client certificate.
The ssl_bc_hsk_err will then need to be expanded to catch other types of
errors.
This change is also applied to the frontend fetches (ssl_fc_hsk_err
becomes ssl_fc_err) and to their string counterparts.
In case of a connection error happening after the SSL handshake is
completed, the error code stored in the connection structure would not
always be set, hence having some connection failures being described as
successful in the fc_conn_err or bc_conn_err sample fetches.
The most common case in which it could happen is when the SSL server
rejects the client's certificate. The SSL_do_handshake call on the
client side would be sucessful because the client effectively sent its
client hello and certificate information to the server, but the next
call to SSL_read on the client side would raise an SSL_ERROR_SSL code
(through the SSL_get_error function) which is decribed in OpenSSL
documentation as a non-recoverable and fatal SSL error.
This patch ensures that in such a case, the connection's error code is
set to a special CO_ERR_SSL_FATAL value.
Checking in code the right keyword is "enabled" and not "enable".
In addition the comment was also completed:
This could appear useless because the "defaults" sections not
yet apply on "peers" sections, but it could be the case in the future.
This statement can currently cancel a previous "disabled" keyword in
the same section.
This patch should be backported in all supported branches (keyword
is present since 1.5)

The "process" directive on "bind" lines becomes quite confusing considering
that the only allowed value is 1 for the process, and that threads are
optional and come after the mandatory "1/".
Let's introduce a new "thread" directive to directly configure thread
numbers, and mark "process" as deprecated. Now "process" will emit a
warning and will suggest how to be replaced with "thread" instead.
The doc was updated accordingly (mostly a copy-paste of the previous
description which was already up to date).
This is marked as MEDIUM as it will impact users having "zero-warning"
and "process" specified.

- BUG/MINOR: config: reject configs using HTTP with bufsize >= 256 MB

In ticket #1348 some users expressed some concerns regarding the removal
of the "grace" directive from the proxies. Their use case very closely
mimmicks the original intent of the grace keyword, which is, let haproxy
accept traffic for some time when stopping, while indicating an external
LB that it's stopping.
This is implemented here by starting a task whose expiration triggers
the soft-stop for real. The global "stopping" variable is immediately
set however. For example, this below will be sufficient to instantly
notify an external check on port 9999 that the service is going down,
while other services remain active for 10s:
global
grace 10s
frontend ext-check
bind :9999
monitor-uri /ext-check
monitor fail if { stopping }

It is quite common to see in configurations constructions like the
following one:
http-request set-var(txn.bodylen) 0
http-request set-var(txn.bodylen) req.hdr(content-length)
...
http-request set-header orig-len %[var(txn.bodylen)]
The set-var() rules are almost always duplicated when manipulating
integers or any other value that is mandatory along operations. This is
a problem because it makes the configurations complicated to maintain
and slower than needed. And it becomes even more complicated when several
conditions may set the same variable because the risk of forgetting to
initialize it or to accidentally reset it is high.
This patch extends the var() sample fetch function to take an optional
argument which contains a default value to be returned if the variable
was not set. This way it becomes much simpler to use the variable, just
set it where needed, and read it with a fall back to the default value:
http-request set-var(txn.bodylen) req.hdr(content-length)
...
http-request set-header orig-len %[var(txn.bodylen,0)]
The default value is always passed as a string, thus it will experience
a cast to the output type. It doesn't seem userful to complicate the
configuration to pass an explicit type at this point.
The vars.vtc regtest was updated accordingly.
Just like the set-var-fmt action for tcp/http rules, the set-var-fmt
directive in global sections allows to pre-set process-wide variables
using a format string instead of a sample expression. This is often
more convenient when it is required to concatenate multiple fields,
or when emitting just one word.
The set-var() action is convenient because it preserves the input type
but it's a pain to deal with when trying to concatenate values. The
most recurring example is when it's needed to build a variable composed
of the source address and the source port. Usually it ends up like this:
tcp-request session set-var(sess.port) src_port
tcp-request session set-var(sess.addr) src,concat(":",sess.port)
This is even worse when trying to aggregate multiple fields from stick-table
data for example. Due to this a lot of users instead abuse headers from HTTP
rules:
http-request set-header(x-addr) %[src]:%[src_port]
But this requires some careful cleanups to make sure they won't leak, and
it's significantly more expensive to deal with. And generally speaking it's
not clean. Plus it must be performed for each and every request, which is
expensive for this common case of ip+port that doesn't change for the whole
session.
This patch addresses this limitation by implementing a new "set-var-fmt"
action which performs the same work as "set-var" but takes a format string
in argument instead of an expression. This way it becomes pretty simple to
just write:
tcp-request session set-var-fmt(sess.addr) %[src]:%[src_port]
It is usable in all rulesets that already support the "set-var" action.
It is not yet implemented for the global "set-var" directive (which already
takes a string) and the CLI's "set var" command, which would definitely
benefit from it but currently uses its own parser and engine, thus it
must be reworked.
The doc and regtests were updated.
There is a massive abuse of copy-paste in the doc that is visible in
the examples and arguments declaration. Let's at least remove irrelevant
examples for now.
Sometimes it is convenient to remap large sets of URIs to new ones (e.g.
after a site migration for example). This can be achieved using
"http-request redirect" combined with maps, but one difficulty there is
that non-matching entries will return an empty response. In order to
avoid this, duplicating the operation as an ACL condition ending in
"-m found" is possible but it becomes complex and error-prone while it's
known that an empty URL is not valid in a location header.
This patch addresses this by improving the redirect rules to be able to
simply ignore the rule and skip to the next one if the result of the
evaluation of the "location" expression is empty. However in order not
to break existing setups, it requires a new "ignore-empty" keyword.
There used to be an ACT_FLAG_FINAL on redirect rules that's used during
the parsing to emit a warning if followed by another rule, so here we
only set it if the option is not there. The http_apply_redirect_rule()
function now returns a 3rd value to mention that it did nothing and
that this was not an error, so that callers can just ignore the rule.
The regular "redirect" rules were not modified however since this does
not apply there.
The map_redirect VTC was completed with such a test and updated to 2.5
and an example was added into the documentation.
The bc_conn_err and bc_conn_err_str sample fetches give the status of
the connection on the backend side. The error codes and error messages
are the same than the ones that can be raised by the fc_conn_err fetch.
This new sample fetch along the ssl_bc_hsk_err_str fetch contain the
last SSL error of the error stack that occurred during the SSL
handshake (from the backend's perspective).
This option can be used to define a specific log format that will be
used in case of error, timeout, connection failure on a frontend... It
will be used for any log line concerned by the log-separate-errors
option. It will also replace the format of specific error messages
decribed in section 8.2.6.
If no "error-log-format" is defined, the legacy error messages are still
emitted and the other error logs keep using the regular log-format.
This option will be replaced by a "error-log-format" that enables to use
a dedicated log-format for connection error messages instead of the
regular log-format (in which most of the fields would be invalid in such
a case).
The "log-error-via-logformat" mechanism will then be replaced by a test
on the presence of such an error log format or not. If a format is
defined, it is used for connection error messages, otherwise the legacy
error log format is used.

To be able to provide JA3 compatible TLS Fingerprints we need to expose
all Client Hello captured data using fetchers. Patch provides new
and modifies existing fetchers to add ability to filter out GREASE values:
- ssl_fc_cipherlist_*
- ssl_fc_ecformats_bin
- ssl_fc_eclist_bin
- ssl_fc_extlist_bin
- ssl_fc_protocol_hello_id
When we set tune.ssl.capture-cipherlist-size to a non-zero value
we are able to capture cipherlist supported by the client. To be able to
provide JA3 compatible TLS fingerprinting we need to capture more
information from Client Hello message:
- SSL Version
- SSL Extensions
- Elliptic Curves
- Elliptic Curve Point Formats
This patch allows HAProxy to capture such information and store it for
later use.

In case of connection failure, a dedicated error message is output,
following the format described in section "Error log format" of the
documentation. These messages cannot be configured through a log-format
option.
This patch adds a new option, "dontloglegacyconnerr", that disables
those error logs when set, and "replaces" them by a regular log line
that follows the configured log-format (thanks to a call to sess_log in
session_kill_embryonic).
The new fc_conn_err sample fetch allows to add the legacy error log
information into a regular log format.
This new option is unset by default so the logging logic will remain the
same until this new option is used.
This new sample fetch along the ssl_fc_hsk_err_str fetch contain the
last SSL error of the error stack that occurred during the SSL
handshake (from the frontend's perspective). The errors happening during
the client's certificate verification will still be given by the
ssl_c_err and ssl_c_ca_err fetches. This new fetch will only hold errors
retrieved by the OpenSSL ERR_get_error function.
The fc_conn_err and fc_conn_err_str sample fetches give information
about the problem that made the connection fail. This information would
previously only have been given by the error log messages meaning that
thanks to these fetches, the error log can now be included in a custom
log format. The log strings were all found in the conn_err_code_str
function.
This option had always been broken in HTX, which means that the first
breakage appeared in 1.9, that it was broken by default in 2.0 and that
no workaround existed starting with 2.1. The way this option works is
praticularly unfit to the rest of the configuration and to the internal
architecture. It had some uses when it was introduced 14 years ago but
nowadays it's possible to do much better and more reliable using a
set of "http-request set-dst" and "http-request set-uri" rules, which
additionally are compatible with DNS resolution (via do-resolve) and
are not exclusive to normal load balancing. The "option-http_proxy"
example config file was updated to reflect this.
The option is still parsed so that an error message gives hints about
what to look for.

- BUG/MEDIUM: init: restore behavior of command-line "-m" for memory limitation
Now it's possible to form a term using parenthesis around an expression.
This will soon allow to build more complex expressions. For now they're
still pretty limited but parenthesis do work.
Now evaluating a condition will rely on an expression (or an empty string),
and this expression will support ORing a sub-expression with another
optional expression. The sub-expressions ANDs a term with another optional
sub-expression. With this alone precedence between && and || is respected,
and the following expression:
A && B && C || D || E && F || G
will naturally evaluate as:
(A && B && C) || D || (E && F) || G
Define a new global config statement named
"h2-workaround-bogus-websocket-clients".
This statement will disable the automatic announce of h2 websocket
support as specified in the RFC8441. This can be use to overcome clients
which fail to implement the relatively fresh RFC8441. Clients will in
his case automatically downgrade to http/1.1 for the websocket tunnel
if the haproxy configuration allows it.
This feature is relatively simple and can be backported up to 2.4, which
saw the introduction of h2 websocket support.
This reverts commit 19bbbe0562.
For now, set-src/set-src-port actions are directly performed on the client
connection. Using these actions at the stream level is really a problem with
HTTP connection (See #90) because all requests are affected by this change
and not only the current request. And it is worse with the H2, because
several requests can set their source address into the same connection at
the same time.
It is already an issue when these actions are called from "http-request"
rules. It is safer to wait a bit before adding the support to "tcp-request
content" rules. The solution is to be able to set src/dst address on the
stream and not on the connection when the action if performed from the L7
level..
Reverting the above commit means the issue #1303 is no longer fixed.
This patch must be backported in all branches containing the above commit
(as far as 2.0 for now).
This patch makes the use of 'gpc' excluding the use of the legacy
types 'gpc0' and 'gpc1" on the same table.
It also makes the use of 'gpc_rate' excluding the use of the legacy
types 'gpc0_rate' and 'gpc1_rate" on the same table.
The 'gpc0' and 'gpc1' related fetches and actions will apply
to the first two elements of the 'gpc' array if stored in table.
The 'gpc0_rate' and 'gpc1_rate' related fetches and actions will apply
to the first two elements of the 'gpc_rate' array if stored in table.
This patch adds the definition of two new array data_types:
'gpc': This is an array of 32bits General Purpose Counters.
'gpc_rate': This is an array on increment rates of General Purpose Counters.
Like for all arrays, they are limited to 100 elements.
This patch also adds actions and fetches to handle
elements of those arrays.
Note: As documented, those new actions and fetches won't
apply to the legacy 'gpc0', 'gpc1', 'gpc0_rate' nor 'gpc1_rate'.
This patch makes the use of 'gpt' excluding the use of the legacy
type 'gpt0' on the same table.
It also makes the 'gpt0' related fetches and actions applying
to the first element of the 'gpt' array if stored in table.
This patch adds the definition of a new array data_type
'gpt'. This is an array of 32bits General Purpose Tags.
Like for all arrays, it is limited to 100 elements.
This patch also adds actions and fetches to handle
elements of this array.
Note: As documented, those new actions and fetches won't
apply to the legacy 'gpt0' data type.
The store type 'gpt0' was present in code but was not documented.
The patch fix this and should be backported since 'gpt0' is supported.
[wt: ~1.6-dev4 hence all stable]
CREATE USER has been the standard way of creating users since
MySQL-5.0 (2005).
The current syntax of INSERT INTO mysql.user won't actually work
on MariaDB-10.4+.
Because haproxy doesn't use any resources the MySQL executable comment
syntax provides resource contraints to make it more palatable
to risk adverse users.
/*!50701 is a syntax recognised by MySQL and MariaDB 5.7.1+ when
resource contraints where added.
/*M!100201 is a MariaDB executable comment syntax recognised for MariaDB
for the 10.2.1 where the MAX_STATEMENT_TIME was added.
This patch may be backported as far as 2.0.

It is now possible to set the Netfilter MARK and the TOS field value in all
packets sent to the client from any tcp-request rulesets or the "tcp-response
content" one. To do so, the parsing of "set-mark" and "set-tos" actions are
moved in tcp_act.c and the actions evaluation is handled in dedicated functions.
This patch may be backported as far as 2.2 if necessary.
It is now possible to set the "nice" factor of the current stream from a
"tcp-request content" or "tcp-response content" ruleset. To do so, the
action parsing is moved in stream.c and the action evaluation is handled in
a dedicated function.
This patch may be backported as far as 2.2 if necessary.
It is now possible to set the stream log level from a "tcp-request content"
or "tcp-response content" ruleset. To do so, the action parsing is moved in
stream.c and the action evaluation is handled in a dedicated function.
This patch should fix issue #1306. It may be backported as far as 2.2 if
necessary.
set-src/set-src-port and set-dst/set-dst-port actions were not listed in the
documentation of "tcp-request session".
This patch may be backported to all stable versions.
If it possible to set source IP/Port from "tcp-request connection",
"tcp-request session" and "http-request" rules but not from "tcp-request
content" rules. There is no reason for this limitation and it may be a
problem for anyone wanting to call a lua fetch to dynamically set source
IP/Port from a TCP proxy. Indeed, to call a lua fetch, we must have a
stream. And there is no stream when "tcp-request connection/session" rules
are evaluated.
Thanks to this patch, "set-src" and "set-src-port" action are now supported
by "tcp_request content" rules.
This patch is related to the issue #1303. It may be backported to all stable
versions.
This one was deprecated in 2.3 and marked for removal in 2.5. It suffers
too many limitations compared to threads, and prevents some improvements
from being engaged. Instead of a bypassable startup error, there is now
a hard error.
The parsing code was removed, and very few obvious cases were as well.
The code is deeply rooted at certain places (e.g. "for" loops iterating
from 0 to nbproc) so it will not be that trivial to remove everywhere.
The "bind" and "bind-process" parsers will have to be adjusted, though
maybe not completely changed if we later want to support thread groups
for large NUMA machines. Some stats socket restrictions were removed,
and the doc was updated according to what was done. A few places in the
doc still refer to nbproc and will have to be revisited. The master-worker
code also refers to the process number to distinguish between master and
workers and will have to be carefully adjusted. The MAX_PROCS macro was
reset to 1, this will at least reduce the size of some remaining arrays.
Two regtests were dependieng on this directive, one with an explicit
"nbproc 1" and another one testing the master's CLI using nbproc 4.
Both were adapted.
Commit ab0a5192a ("MEDIUM: config: mark "grace" as deprecated") marked
the "grace" keyword as deprecated in 2.3, tentative removal for 2.4
with a hard deadline in 2.5, so let's remove it and return an error now.
This old and outdated feature was incompatible with soft-stop, reload
and socket transfers, and keeping it forced ugly hacks in the lower
layers of the protocol stack.
It was marked as deprecated for immediate removal as it was not used,
let's reject it and remove it from the doc. A specific error suggests
to check tune.bufsize instead.
As specified in the RFC3875 (section 4.1.17), this parameter must be set to
the name and version of the information server software making the CGI
request. Thus, it is now added to the default parameters defined by
HAProxy. It is set to the string "HAProxy $version".
This patch should fix the issue #1285 and must be backported as far as 2.2.
This patch adds the `-cc` (check condition) argument to evaluate conditions on
startup and return the result as the exit code.
As an example this can be used to easily check HAProxy's version in scripts:
haproxy -cc 'version_atleast(2.4)'
This resolves GitHub issue #1246.

This patch fixes a few grammar and spelling issues in configuration.txt.
It was also noted that there was a wide range of case usage
(i.e. haproxy, HAproxy, HAProxy, etc... ). This patch updates them
all to be consistently "HAProxy" except where a binary is mentioned.
When using the crl-file option with multiple Certificate Authority
levels in the CA chain, there must be one CRL per CA or the verify
function on the backend side will raise an "unagle to get certificate
CRL" error (error code 3).
This was required by GitHub issue #1201.
When implementing the server side certificate hot update, the ckch
mechanism was used on the backend side in order to mimic the frontend
certificate management and to enable server line certificate update via
the CLI (see GitHub issue #427). As an unexpected side effect, we now
also look for ssl extra files (cert.pem.key, cert.pem.ocsp ...) for the
backend side.
This patch updates the documentation accordingly.
This answers to GitHub issue #845.
normalize-uri http rule is marked as experimental, so it cannot be
activated without the global 'expose-experimental-directives'. The
associated vtc is updated to be able to use it.
Add a new flag to mark a keyword as experimental. An experimental
keyword cannot be used if the global 'expose-experimental-directives' is
not present first.
Only keywords parsed through a standard cfg_keywords lists in
global/proxies section will be automatically detected if declared
experimental. To support a keyword outside of these lists,
check_kw_experimental must be called manually during its parsing.
If an experimental keyword is present in the config, the tainted flag is
updated.
For the moment, no keyword is marked as experimental.
This one works just like .notice/.warning/.alert except that it prints
the message at level "DIAG" only when haproxy runs in diagnostic mode
(-dD). This can be convenient for example to pass a few hints to help
locate certain config parts or to leave messages about certain temporary
workarounds.
Example:
.diag "WTA/2021-05-07: $.LINE: replace 'redirect' with 'return' after final switch to 2.4"
http-request redirect location /goaway if ABUSE
These predicates respectively verify that the current version is at least
a given version or is before a specific one. The syntax is exactly the one
reported by "haproxy -v", though each component is optional, so both "1.5"
and "2.4-dev18-88910-48" are supported. Missing components equal zero, and
"dev" is below "pre" or "rc", which are both inferior to no such mention
(i.e. they are negative). Thus "2.4-dev18" is older than "2.4-rc1" which
is older than "2.4".
The "feature(name)" predicate will return true if <name> corresponds to
a name listed after a '+' in the features list, that is it was enabled at
build time with USE_<name>=1. Typical use cases will include OPENSSL, LUA
and LINUX_SPLICE. But maybe it will also be convenient to use with optional
addons such as PROMEX and the device detection modules to help keeping the
same configs across various deployments.
"streq(str1,str2)" will return true if the two strings match while
"strneq(str1,str2)" will return true only if they differ. This is
convenient to match an environment variable against a predefined value.
The new pseudo-variables ".FILE", ".LINE" and ".SECTION" will be resolved
on the fly by the config parser and will respectively retrieve the current
configuration file name, the current line number and the current section
being parsed. This may help emit logs, errors, and debugging information
(e.g. which rule matched).
The '.' in the first char was reserved for such pseudo-variables and no
other variable is permitted. This will allow to add support for new ones
in the future if they prove to be useful (e.g. randoms/uuid for secret
keying or automatic naming of configuration objects).

By default haproxy loads all files designated by a relative path from the
location the process is started in. In some circumstances it might be
desirable to force all relative paths to start from a different location
just as if the process was started from such locations. This is what this
directive is made for. Technically it will perform a temporary chdir() to
the designated location while processing each configuration file, and will
return to the original directory after processing each file. It takes an
argument indicating the policy to use when loading files whose path does
not start with a slash ('/').
A few options are offered, "current" (the default), "config" (files
relative to config file's dir), "parent" (files relative to config file's
parent dir), and "origin" with an absolute path.
This should address issue #1198.
The alternative arguments are always in curly brackets, let's fix it for
set-timeout.
The Example in set-timeout does not have the one of the required argument.
This commit makes the PR https://github.com/cbonte/haproxy-dconv/pull/34
obsolete.

Render numa detection optional with a global configuration statement
'no numa-cpu-mapping'. This can be used if the applied affinity of the
algorithm is not optimal. Also complete the documentation with this new
keyword.
Use the platform independent type hap_cpuset for the cpu-map statement
parsing. This allow to address CPU index greater than LONGBITS.
Update the documentation to reflect the removal of this limit except for
platforms without cpu_set_t type or equivalent.
This normalizer removes "/./" segments from the path component.
Usually the dot refers to the current directory which renders those segments redundant.
See GitHub Issue #714.
This patch adds an introduction to the http-request normalize-uri section,
explaining what to expect from the normalizers and possible issues that might
arise when not being careful.
This patch renames all existing uri-normalizers into a more consistent naming
scheme:
1. The part of the URI that is being touched.
2. The modification being performed as an explicit verb.
This normalizer merges `../` path segments with the predecing segment, removing
both the preceding segment and the `../`.
Empty segments do not receive special treatment. The `merge-slashes` normalizer
should be executed first.
See GitHub Issue #714.
This patch adds 4 new sample fetches to get the source and the destination
info (ip address and port) of the backend connection :
* bc_dst : Returns the destination address of the backend connection
* bc_dst_port : Returns the destination port of the backend connection
* bc_src : Returns the source address of the backend connection
* bc_src_port : Returns the source port of the backend connection
The configuration manual was updated accordingly.
With the json_query can a JSON value be extacted from a header
or body of the request and saved to a variable.
This converter makes it possible to handle some JSON workload
to route requests to different backends.
ub64dec and ub64enc are the base64url equivalent of b64dec and base64
converters. base64url encoding is the "URL and Filename Safe Alphabet"
variant of base64 encoding. It is also used in in JWT (JSON Web Token)
standard.
RFC1421 mention in base64.c file is deprecated so it was replaced with
RFC4648 to which existing converters, base64/b64dec, still apply.
Example:

This patch re-works configuration parsing, it removes the "server"
lines from "resolvers" sections introduced in commit 56fc5d9eb:
MEDIUM: resolvers: add supports of TCP nameservers in resolvers.
It also extends the nameserver lines to support stream server
addresses such as:
resolvers
nameserver localhost tcp@127.0.0.1:53
Doing so, a part of nameserver's init code was factorized in
function 'parse_resolvers' and removed from 'post_parse_resolvers'.
An explicit stream address prefix such as "tcp6@" "tcp4@"
"stream+ipv6@" "stream+ipv4@" or "stream+unix@" will
allocate an implicit ring buffer with a forward server
targeting the given address.
This is usefull to simply send logs to a log server in tcp
and It doesn't need to declare a ring section in configuration.
Since the internal function str2sa_range is used to addresses
for different objects ('server', 'bind' but also 'log' or
'nameserver') we notice that some combinations are missing.
"ip@" is introduced to authorize the prefix "dgram+ip@" or
"stream+ip@" which dectects automatically IP version but
specify dgram or stream.
"tcp@" was introduced and is an alias for "stream+ip@".
"tcp6" and "tcp4" are now aliases for "stream+ipv6@" and
"stream+ipv4@".
"uxst@" and "uxdg@" are now aliases for "stream+unix@" and
"dgram+unix@".
This patch also adds a complete section in documentation to
describe adresses and their prefixes.
HTTP_2.0 predefined macro returns true for HTTP/2 requests. HTTP/2 doen't
convey a version information, so this macro may seem a bit strange. But for
compatiblity reasons, internally, the "HTTP/2.0" version is set. Thus, it is
handy to rely on it to differenciate HTTP/1 and HTTP/2 requests.
Some predefined ACLs were still based on deprecated sample fetches, like
req_proto_http or req_ver. Now, they use non-deprecated sample fetches. In
addition, the usage lines in the configuration manual have been updated to
be more explicit.

- DOC: clarify that compression works for HTTP/2
This patch clarifies that compression also works with HTTP/2. I have
picked the wording "HTTP/1.1 or above" because it is already used
elsewhere in the documentation.
I have tested that compression indeed works in HTTP/2.
Signed-off-by: Julien Pivotto <roidelapluie@inuits.eu>
This one is the last optional module to build with haproxy, so let's move
it to addons/. It was renamed to "ot" as it was the only one whose USE_*
option did not match the directory name, now this is consistent.
Few changes were required, only the Makefile, and doc were adjusted, as
the directory was already self-contained and relocatable.
Historically, an option was added to wait for the request payload (option
http-buffer-request). This option has 2 drawbacks. First, it is an ON/OFF
option for the whole proxy. It cannot be enabled on demand depending on the
message. Then, as its name suggests, it only works on the request side. The
only option to wait for the response payload was to write a dedicated
filter. While it is an acceptable solution for complex applications, it is a
bit overkill to simply match strings in the body.
To make everyone happy, this patch adds a dedicated HTTP action to wait for
the message payload, for the request or the response depending it is used in
an http-request or an http-response ruleset. The time to wait is
configurable and, optionally, the minimum payload size to have before stop
to wait.
Both the http action and the old http analyzer rely on the same internal
function.
Use a L6 sample fetch on an HTX streams or a HTX health-check is meaningless
because data are not raw but structured. So now, these sample fetches fail
when called from an HTTP proxy. In addition, a warning has been added in the
configuration manual, at the begining of the L6 sample fetches section.
Note that req.len and res.len samples return the HTX data size instead of
failing. It is not accurate because it does not reflect the buffer size nor
the raw data length. But we keep it for backward compatibility purpose.
However it remains a bit strange to use it on an HTTP proxy.
This patch may be backported to all versions supporting the HTX, i.e as far
as 2.0. But the part about the health-checks is only valid for the 2.2 and
upper.
This patch adds explanation about chaining a TCP frontend to an HTTP
backend. It also explain how the HTTP upgrades work in this context. A note
has also been added in "Fetching HTTP samples" section to warning about HTTP
content processing in TCP.
It is now possible to perform HTTP upgrades on a TCP stream from the
frontend side. To do so, a tcp-request content rule must be defined with the
switch-mode action, specifying the mode (for now, only http is supported)
and optionnaly the proto (h1 or h2).
This way it could be possible to set HTTP directives on a TCP frontend which
will only be evaluated if an upgrade is performed. This new way to perform
HTTP upgrades should replace progressively the old way, consisting to route
the request to an HTTP backend. And it should be also a good start to remove
all HTTP processing from tcp-request content rules.
This action is terminal, it stops the ruleset evaluation. It is only
available on proxy with the frontend capability.
The configuration manual has been updated accordingly.
This patch adds a description about information provided by "haproxy -vv"
command regarding the available protocols. The description is adapted
depending the context (bind line, server line or health-check).

While we do support process-wide variables ("proc.<name>"), there was
no way to preset them from the configuration. This was particularly
limiting their usefulness since configs involving them always had to
first check if the variable was set prior to performing an operation.
This patch adds a new "set-var" directive in the global section that
supports setting the proc.<name> variables from an expression, like
other set-var actions do. The syntax however follows what is already
being done for setenv, which consists in having one argument for the
variable name and another one for the expression.
Only "constant" expressions are allowed here, such as "int", "str"
etc, combined with arithmetic or string converters, and variable
lookups. A few extra sample fetch keywords like "date", "rand" and
"uuid" are also part of the constant expressions and may make sense
to allow to create a random key or differentiate processes.
The way it was done consists in parsing a dummy rule an executing the
expression in the CFG_PARSE context, then releasing the expression.
This is safe because the sample that variables store does not hold a
back pointer to expression that created them.
The hdr_ip() sample fetch function will try to extract IP addresses
from a header field. These IP addresses are parsed using url2ipv4()
and if it fails it will fall back to inet_pton(AF_INET6), otherwise
will fail.
There is a small problem there which is that if a field starts with
an IP address and is immediately followed by some garbage, the IP
address part is still returned. This is a problem with fields such
as x-forwarded-for because it prevents detection of accidental
corruption or bug along the chain. For example, the following string:
x-forwarded-for: 1.2.3.4; 5.6.7.8
or this one:
x-forwarded-for: 1.2.3.4O ( the last one being the letter 'O')
would still return "1.2.3.4" despite the trailing characters. This is
bad because it will silently cover broken code running on intermediary
proxies and may even in some cases allow haproxy to pass improperly
formatted headers after they were apparently validated, for example,
if someone extracts the address from this field to place it into
another one.
This issue would only affect the IPv4 parser, because the IPv6 parser
already uses inet_pton() which fails at the first invalid character and
rejects trailing port numbers.
In strict compliance with RFC7239, let's make sure that if there are any
characters left in the string, the parsing fails and makes hdr_ip()
return nothing. However, a special case has to be handled to support
IPv4 addresses followed by a colon and a valid port number, because till
now the parser used to implicitly accept them and it appears that this
practice, though rare, does exist at least in Azure:
https://docs.microsoft.com/en-us/azure/application-gateway/how-application-gateway-works
This issue has always been there so the fix may be backported to all
versions. It will need the following commit in order to work as expected:
MINOR: tools: make url2ipv4 return the exact number of bytes parsed

The recent default runqueue size reduction appeared to have significantly
lowered performance on low-thread count configs. Testing various values
runqueue values on different workloads under thread counts ranging from
1 to 64, it appeared that lower values are more optimal for high thread
counts and conversely. It could even be drawn that the optimal value for
various workloads sits around 280/sqrt(nbthread), and probably has to do
with both the L3 cache usage and how to optimally interlace the threads'
activity to minimize contention. This is much easier to optimally
configure, so let's do this by default now.
The recently introduced Financial Information eXchange (FIX)
converters have some hard coded tags based on the specification that
were misspelled. Specifically, SenderComID and TargetComID should
be SenderCompID and TargetCompID according to the specification [1][2].
This patch updates all references, which includes the converters
themselves, the regression test, and the documentation.

Parameter "accepted_payload_size" is currently considered regardless
the used nameserver is using TCP or UDP. It remains mandatory to annouce
such capability to support e-dns, so a value have to be announced also
in TCP. Maximum DNS message size in TCP is limited by protocol to 65535
and so for UDP (65507) if system supports such UDP messages. But
the maximum value for this option was arbitrary forced to 8192.
This patch change this maximum to 65535 to allow user to set bigger value
for UDP if its system supports. It also sets accepted_payload_size
in TCP allowing to retrieve huge responses if the configuration uses
TCP nameservers.
The request announcing the accepted_payload_size capability is currently
built at resolvers level and is common to all used nameservers of the
section regardess transport protocol used. A further patch should be
made to at least specify a different payload size depending of the
transport, and perhaps could be forced to 65535 in case of TCP and
maximum would be forced back to 65507 matching UDP max.
This patch is appliable since 2.4 version
