In order to ensure that an instant restart of the process will not wipe
precious debugging information, and to leave time for an admin to archive
a copy of a ring, now upon startup, any previously existing file will be
renamed with the extra suffix ".bak", and any previously existing file
with suffix ".bak" will be removed.
This mmaps a file which will serve as the backing-store for the ring's
contents. The idea is to provide a way to retrieve sensitive information
(last logs, debugging traces) even after the process stops and even after
a possible crash. Right now this was possible by connecting to the CLI
and dumping the contents of the ring live, but this is not handy and
consumes quite a bit of resources before it is needed.
With a backing file, the ring is effectively RAM-mapped file, so that
contents stored there are the same as those found in the file (the OS
doesn't guarantee immediate sync but if the process dies it will be OK).
Note that doing that on a filesystem backed by a physical device is a
bad idea, as it will induce slowdowns at high loads. It's really
important that the device is RAM-based.
Also, this may have security implications: if the file is corrupted by
another process, the storage area could be corrupted, causing haproxy
to crash or to overwrite its own memory. As such this should only be
used for debugging.

This will allows nbtgroups > 1 to be declared in the config without
recompiling. The theoretical limit is 64, though we'd rather not push
it too far for now as some structures might be enlarged to be indexed
per group. Let's start with 16 groups max, allowing to experiment with
dual-socket machines suffering from up to 8 loosely coupled L3 caches.
It's a good start and doesn't engage us too far.
The principle remains the same, but instead of having a single process
and ignoring extra ones, now we set the affinity masks for the respective
threads of all groups.
The doc was updated with a few extra examples.
It was deprecated, marked for removal in 2.7 and was already emitting a
warning, let's get rid of it. Note that we've kept the keyword detection
to suggest to use "thread" instead.
This was already causing a deprecation warning and was marked for removal
in 2.7, now it happens. An error message indicates this doesn't exist
anymore.
The output of "show activity" can be so large that the output is visually
unreadable on a screen. Let's add an option to filter on the desired
column (actually the thread number), use "0" to report only the first
column (aggregated/sum/avg), and use "-1", the default, for the normal
detailed dump.

- MEDIUM: bwlim: Add support of bandwith limitation at the stream level
This patch adds a filter to limit bandwith at the stream level. Several
filters can be defined. A filter may limit incoming data (upload) or
outgoing data (download). The limit can be defined per-stream or shared via
a stick-table. For a given stream, the bandwith limitation filters can be
enabled using the "set-bandwidth-limit" action.
A bandwith limitation filter can be used indifferently for HTTP or TCP
stream. For HTTP stream, only the payload transfer is limited. The filter is
pretty simple for now. But it was designed to be extensible. The current
design tries, as far as possible, to never exceed the limit. There is no
burst.
It looks like we'll need:
- one share timers queue for the rare tasks that need to wake up
anywhere
- one private timers queue per thread
- one global queue per group
- one local queue per thread
And may be we can simply get rid of any global/shared run queue as
we don't seem to have any task bound to a subset of threads.
This macro was used both for binding and for lookups. When binding tasks
or FDs, using all_threads_mask instead is better as it will later be per
group. For lookups, ~0UL always does the job. Thus in practice the macro
was already almost not used anymore since the rest of the code could run
fine with a constant of all ones there.
Instead of having a global mask of all the profiled threads, let's have
one flag per thread in each thread's flags. They are never accessed more
than one at a time an are better located inside the threads' contexts for
both performance and scalability.
This changes the default from RFC 7540's default 65535 (64k-1) to avoid
avoid some degenerative WINDOW_UPDATE behaviors in the wild observed with
clients using 65536 as their buffer size, and have to complete each block
with a 1-byte frame, which with some servers tend to degenerate in 1-byte
WU causing more 1-byte frames to be sent until the transfer almost only
uses 1-byte frames.
More details here: https://github.com/nghttp2/nghttp2/issues/1722
As mentioned in previous commit (MEDIUM: mux-h2: try to coalesce outgoing
WINDOW_UPDATE frames) the issue could not be reproduced with haproxy but
individual WU frames are sent so theoretically nothing prevents this from
happening. As such it should be backported as a workaround for already
deployed clients after watching for any possible side effect with rare
clients. As an added benefit, uploads from curl now use less DATA frames
(all are 16384 now). Note that the previous patch alone is sufficient to
stop the issue with curl in case this one would need to be reverted.

The HTML version appeared with sections in a different order where
3.3.10..3.3.16 were placed between 3.3.1 and 3.3.2. This patch just slips
them into an intermediary section so that we now have "basic features",
"standard features", and "advanced features".
Some users misunderstood that the parameter of gpc() gpt()
store types on the table line presents the number of elements
of the array to store and not an index of gpt/gpc tag/counter.
This patch adds some explanations.
This patch addresses github issue #1630
It should be backorted in until branch 2.5.
This patch fix the port number and addresses on the example
to match those of the old format.
This patch address the github issue #1492
This patch should be backported until version 2.0
This patch add some details to know which rules are updating
the expiration timer of an entry.
It also adds a comment to know how to fetch a value without renewing
this timer.
This patch addresses github issue #615
This patch should be backported on all still supported branches
Let's make it clear in the peers documentation that not all server
parameters may be used, as there is some confusion around this, and
the doc was even misleading by saying that all parameters were
supported.
This should address github issue #919.
The "sequence" and "entities" diagrams have become so much outdated that
they are at best confusing, but more generally wrong. Let's simply remove
them.
Rename "tune.quic.conn-buf-limit" to "tune.quic.frontend.conn-tx-buffers.limit"
to reflect the stream direction (TX) and the objects (frontends) which are
concerned.
Add tunable "tune.quic.frontend.max_streams_bidi" setting for QUIC frontends
to set the "initial_max_streams_bidi" transport parameter.
Add some documentation for this new setting.
Add two tunable settings both for backends and frontends "max_idle_timeout"
QUIC transport parameter, "tune.quic.frontend.max-idle-timeout" and
"tune.quic.backend.max-idle-timeout" respectively.
cfg_parse_quic_time() has been implemented to parse a time value thanks
to parse_time_err(). It should be reused for any tunable time value to be
parsed.
Add the documentation for this tunable setting only for frontend.

- DOC: internal: add a description of the stream connectors and descriptors
The "layers" mini-doc shows how streams, stconn, sedesc, conns, applets
and muxes interact, with field names, pointers and invariants. It should
be completed but already provides a quick overview about what can be
guaranteed at any step and at different layers.
The stream connector replaced the conn_stream and the sc_conn_io_cb()
function appeared. There's no place there to mention the endpoint
descriptor, but a separate diagram showing the relation between stream
and endpoint via the connector would be nice.
We used to support both RTSP and HTTP protocol version names with and
without accept-invalid-http-request, but since this is based on the
characters themselves, any protocol made of chars {0-9/.HPRST} was
possible and not others. Now that such non-standard protocols are
restricted to accept-invalid-http-request, there's no reason for not
allowing other letters. With this patch, characters {0-9./A-Z} are
permitted when the option is set.

- CI: determine actual OpenSSL version dynamically
When loading providers with 'ssl-provider' global options, this
ssl-provider-path option can be used to set the search path that is to
be used by openssl. It behaves the same way as the OPENSSL_MODULES
environment variable.
When HAProxy is linked to an OpenSSLv3 library, this option can be used
to load a provider during init. You can specify multiple ssl-provider
options, which will be loaded in the order they appear. This does not
prevent OpenSSL from parsing its own configuration file in which some
other providers might be specified.
A linked list of the providers loaded from the configuration file is
kept so that all those providers can be unloaded during cleanup. The
providers loaded directly by OpenSSL will be freed by OpenSSL.
This option can be used to define a default property query used when
fetching algorithms in OpenSSL providers. It follows the format
described in https://www.openssl.org/docs/man3.0/man7/property.html.
It is only available when haproxy is built with SSL support and linked
to OpenSSLv3 libraries.
The "http-restrict-req-hdr-names" option can now be set to restrict allowed
characters in the request header names to the "[a-zA-Z0-9-]" charset.
Idea of this option is to not send header names with non-alphanumeric or
hyphen character. It is especially important for FastCGI application because
all those characters are converted to underscore. For instance,
"X-Forwarded-For" and "X_Forwarded_For" are both converted to
"HTTP_X_FORWARDED_FOR". So, header names can be mixed up by FastCGI
applications. And some HAProxy rules may be bypassed by mangling header
names. In addition, some non-HTTP compliant servers may incorrectly handle
requests when header names contain characters ouside the "[a-zA-Z0-9-]"
charset.
When this option is set, the policy must be specify:
* preserve: It disables the filtering. It is the default mode for HTTP
proxies with no FastCGI application configured.
* delete: It removes request headers with a name containing a character
outside the "[a-zA-Z0-9-]" charset. It is the default mode for
HTTP backends with a configured FastCGI application.
* reject: It rejects the request with a 403-Forbidden response if it
contains a header name with a character outside the
"[a-zA-Z0-9-]" charset.
The option is evaluated per-proxy and after http-request rules evaluation.
This patch may be backported to avoid any secuirty issue with FastCGI
application (so as far as 2.2).

Valerio Pachera explained [1] that external checks would benefit from
having a variable indicating if SSL is being used or not on the server
being checked, and the discussion derived to also indicating the protocol
in use.
This patch adds two environment variables for external checks:
- HAPROXY_SERVER_SSL: equals "0" when SSL is not used, "1" when it is
- HAPROXY_SERVER_PROTO: contains one of the following words to describe
the protocol used with this server:
- "cli": the haproxy CLI. Normally not seen
- "syslog": this is a syslog TCP server
- "peers": this is a peers TCP server
- "h1": this is an HTTP/1.x server
- "h2": this is an HTTP/2 server
- "tcp": this is any other TCP server
The patch is very simple, and may be backported to recent versions if
needed. This closes github issue #1692.
[1] https://www.mail-archive.com/haproxy@formilux.org/msg42233.html
Since the 2.5, for security reason, HTTP/1.0 GET/HEAD/DELETE requests with a
payload are rejected (See e136bd12a "MEDIUM: mux-h1: Reject HTTP/1.0
GET/HEAD/DELETE requests with a payload" for details). However it may be an
issue for old clients.
To avoid any compatibility issue with such clients,
"h1-accept-payload-with-any-method" global option was added. It must only be
set if there is a good reason to do so because it may lead to a request
smuggling attack on some servers or intermediaries.
This patch should solve the issue #1691. it may be backported to 2.5.
It could be usefull to set a ASCII secret which could be used for different
usages. For instance, it will be used to derive QUIC stateless reset tokens.

Low footprint client machines may not have enough memory to download a
complete 16KB TLS record at once. With the new option the maximum
record size can be defined on the server side.
Note: Before limiting the the record size on the server side, a client should
consider using the TLS Maximum Fragment Length Negotiation Extension defined
in RFC6066.
This patch fixes GitHub issue #1679.
If the "close-spread-time" option is set to "infinite", active
connection closing during a soft-stop can be disabled. The 'connection:
close' header or the GOAWAY frame will not be added anymore to the
server's response and active connections will only be closed once the
clients disconnect. Idle connections will not be closed all at once when
the soft-stop starts anymore, and each idle connection will follow its
own timeout based on the multiple timeouts set in the configuration (as
is the case during regular execution).
This feature request was described in GitHub issue #1614.
This patch should be backported to 2.5. It depends on 'MEDIUM: global:
Add a "close-spread-time" option to spread soft-stop on time window'.
On some systems, the hard limit for ulimit -n may be huge, in the order
of 1 billion, and using this to automatically compute maxconn doesn't
work as it requires way too much memory. Users tend to hard-code maxconn
but that's not convenient to manage deployments on heterogenous systems,
nor when porting configs to developers' machines. The ulimit-n parameter
doesn't work either because it forces the limit. What most users seem to
want (and it makes sense) is to respect the system imposed limits up to
a certain value and cap this value. This is exactly what fd-hard-limit
does.
This addresses github issue #1622.
Almost all of our hash-based LB algorithms are implemented as special
cases of something that can now be achieved using sample expressions,
and some of them have adopted some options to adapt their behavior in
ways that could also be achieved using converters.
There are users who want to hash other parameters that are combined
into variables, and who set headers from these values and use
"balance hdr(name)" for this.
Instead of constantly implementing specific options and having users
hack around when they want a real hash, let's implement a native hash
mode that applies to a standard sample expression. This way, any
fetchable element (including variables) may be used to construct the
hash, even modified by any converter if desired.

- DOC: remove my name from the config doc
I was surprised to notice that my name was still present as the author
at the top of the config manual. It turns out that this line and a few
other ones in this file remained unchanged since commit 6a06a40501 that
added this doc 15 years ago! It's long been time to get rid of this!
This adds a call to function <fct> to the list of functions to be called at
the step just before the configuration validity checks. This is useful when you
need to create things like it would have been done during the configuration
parsing and where the initialization should continue in the configuration
check.
It could be used for example to generate a proxy with multiple servers using
the configuration parser itself. At this step the trash buffers are allocated.
Threads are not yet started so no protection is required. The function is
expected to return non-zero on success, or zero on failure. A failure will make
the process emit a succinct error message and immediately exit.
Starting from OpenSSLv3, providers are at the core of cryptography
functions. Depending on the provider used, the way the SSL
functionalities work could change. This new 'show ssl providers' CLI
command allows to show what providers were loaded by the SSL library.
This is required because the provider configuration is exclusively done
in the OpenSSL configuration file (/usr/local/ssl/openssl.cnf for
instance).
A new line is also added to the 'haproxy -vv' output containing the same
information.
DHE ciphers do not present a security risk if the key is big enough but
they are slow and mostly obsoleted by ECDHE. This patch removes any
default DH parameters. This will effectively disable all DHE ciphers
unless a global ssl-dh-param-file is defined, or
tune.ssl.default-dh-param is set, or a frontend has DH parameters
included in its PEM certificate. In this latter case, only the frontends
that have DH parameters will have DHE ciphers enabled.
Adding explicitely a DHE ciphers in a "bind" line will not be enough to
actually enable DHE. We would still need to know which DH parameters to
use so one of the three conditions described above must be met.
This request was described in GitHub issue #1604.

- MEDIUM: global: Add a "close-spread-time" option to spread soft-stop on time window
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.
It's difficult from outside haproxy to detect the supported keywords
and syntax. Interestingly, many of our modern keywords are enumerated
since they're registered from constructors, so it's not very hard to
enumerate most of them.
This patch creates some basic infrastructure to support dumping existing
keywords from different classes on stdout. The format will differ depending
on the classes, but the idea is that the output could easily be passed to
a script that generates some simple syntax highlighting rules, completion
rules for editors, syntax checkers or config parsers.
The principle chosen here is that if "-dK" is passed on the command-line,
at the end of the parsing the registered keywords will be dumped for the
requested classes passed after "-dK". Special name "help" will show known
classes, while "all" will execute all of them. The reason for doing that
after the end of the config processor is that it will also enumerate
internally-generated keywords, Lua or even those loaded from external
code (e.g. if an add-on is loaded using LD_PRELOAD). A typical way to
call this with a valid config would be:
./haproxy -dKall -q -c -f /path/to/config
If there's no config available, feeding /dev/null will also do the job,
though it will not be able to detect dynamically created keywords, of
course.
This patch also updates the management doc.
For now nothing but the help is listed, various subsystems will follow
in subsequent patches.
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.

Dynamic servers feature is now judged to be stable enough. Remove the
experimental-mode requirement for "add/del server" commands. This should
facilitate dynamic servers adoption.
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.

The pools currently have plenty of options (and some usefull ones were
even lost with the modern design), but most of them could be categorized
along a few use cases, namely, performance, reliability, debuggability.
This document explores various ways to try to combine them and their
effect in a less complex way for the long term.
The 9 currently available debugging options may now be checked, set, or
cleared using -dM. The directive now takes a comma-delimited list of
options after the optional poisonning byte. With "help", the list of
available options is displayed with a short help and their current
status.
The management doc was updated.
The STG_REGISTER init level is used to register known keywords and
protocol stacks. It must be called earlier because some of the init
code already relies on it to be known. For example, "haproxy -vv"
for now is constrained to start very late only because of this.
This patch moves it between STG_LOCK and STG_ALLOC, which is fine as
it's used for static registration.
The poisonning performed on pool_free() used to help a little bit with
use-after-free detection, but usually did more harm than good in that
it was never possible to perform post-mortem analysis on released
objects once poisonning was enabled on allocation. Now that there is
a dedicated DEBUG_POOL_INTEGRITY, let's get rid of this annoyance
which is not even documented in the management manual.
Add the ability to set a "server timeout" on the httpclient with either
the httpclient_set_timeout() API or the timeout argument in a request.
Issue #1470.
The 'dst' optionnal field on a httpclient request can be used to set an
alternative server address in the haproxy address format. Which means it
could be use with unix@, ipv6@ etc.
Should fix issue #1471.
"mcli-debug-mode on" enables every command that were meant for a worker,
on the CLI of the master. Which mean you can issue, "show fd", show
stat" in order to debug the MASTER proxy.
You can also combine it with "expert-mode on" or "experimental-mode on"
to access to more commands.

Mentions of the new database update runtime mode and update of
the legit module and the dummy part too.
Note the DeviceAtlas C API version 2.4.0 minimum required
alongside with libCURL, libzip and libgz.
This new option, when set, will cause the callers of pool_alloc() and
pool_free() to be recorded into an extra area in the pool that is expected
to be helpful for later inspection (e.g. in core dumps). For example it
may help figure that an object was released to a pool with some sub-fields
not yet released or that a use-after-free happened after releasing it,
with an immediate indication about the exact line of code that released
it (possibly an error path).
This only works with the per-thread cache, and even objects refilled from
the shared pool directly into the thread-local cache will have a NULL
there. That's not an issue since these objects have not yet been freed.
It's worth noting that pool_alloc_nocache() continues not to set any
caller pointer (e.g. when the cache is empty) because that would require
a possibly undesirable API change.
The extra cost is minimal (one pointer per object) and this completes
well with DEBUG_POOL_INTEGRITY.
When enabled, objects picked from the cache are checked for corruption
by comparing their contents against a pattern that was placed when they
were inserted into the cache. Objects are also allocated in the reverse
order, from the oldest one to the most recent, so as to maximize the
ability to detect such a corruption. The goal is to detect writes after
free (or possibly hardware memory corruptions). Contrary to DEBUG_UAF
this cannot detect reads after free, but may possibly detect later
corruptions and will not consume extra memory. The CPU usage will
increase a bit due to the cost of filling/checking the area and for the
preference for cold cache instead of hot cache, though not as much as
with DEBUG_UAF. This option is meant to be usable in production.
This command was integrated in 2.4 when it was not possible to handle
SSL with dynamic servers, this is now possible so we should prefer this
way.
Must be backported in 2.5.
While giving a fresh try to `set server ssl` (which I wrote), I realised
the behavior is a bit inconsistent. Indeed when using this command over
a server with ssl enabled for the data path but also for the health
check path we have:
- data and health check done using tls
- emit `set server be_foo/srv0 ssl off`
- data path and health check path becomes plain text
- emit `set server be_foo/srv0 ssl on`
- data path becomes tls and health check path remains plain text
while I thought the end result would be:
- data path and health check path comes back in tls
In the current code we indeed erase all connections while deactivating,
but restore only the data path while activating. I made this mistake in
the past because I was testing with a case where the health check plain
text by default.
There are several ways to solve this issue. The cleanest one would
probably be to avoid changing the health check connection when we use
`set server ssl` command, and create a new command `set server
ssl-check` to change this. For now I assumed this would be ok to simply
avoid changing the health check path and be more consistent.
This patch tries to address that and also update the documentation. It
should not break the existing usage with health check on plain text, as
in this case they should have `no-check-ssl` in defaults. Without this
patch, it makes the command unusable in an env where you have a list of
server to add along the way with initial `server-template`, and all
using tls for data and healthcheck path.
For 2.6 we should probably reconsider and add `set server ssl-check`
command for better granularity of cases.
If this solution is accepted, this patch should be backported up to >=
2.4.
The alternative solution was to restore the previous state, but I
believe this will create even more confusion in the future.

The purpose here is to explain how memory pools work, what their
architecture is depending on the build options (4 possible combinations),
and how the various build options affect their behavior.
Two pool-specific macros that were previously documented in initcalls
were moved to pools.txt.
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.

This is a second help to dump loaded library names late at boot, once
external code has already been initialized. The purpose is to provide
a format that makes it easy to pass to "tar" to produce an archive
containing the executable and the list of dependencies. For example
if haproxy is started as "haproxy -f foo.cfg", a config check only
will suffice to quit before starting, "-q" will be used to disable
undesired output messages, and -dL will be use to dump libraries.
This will result in such a command to trivially produce a tarball
of loaded libraries:
./haproxy -q -c -dL -f foo.cfg | tar -T - -hzcf archive.tgz
Many times core dumps reported by users who experience trouble are
difficult to exploit due to missing system libraries. Sometimes,
having just a list of loaded libraries and their respective addresses
can already provide some hints about some problems.
This patch makes a step in that direction by adding a new "show libs"
command that will try to enumerate the list of object files that are
loaded in memory, relying on the dynamic linker for this. It may also
be used to detect that some foreign code embarks other undesired libs
(e.g. some external Lua modules).
At the moment it's only supported on glibc when USE_DL is set, but it's
implemented in a way that ought to make it reasonably easy to be extended
to other platforms.
There were empty lines in the output of the CLI's "show ssl
ocsp-response" command (after the certificate ID and between two
certificates). This patch removes them since an empty line should mark
the end of the output.
Must be backported in 2.5.
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.
This patch implements a simple "show version" command which returns
the version of the current process.
It's available from the master and the worker processes, so it is easy
to check if the master and the workers have the same version.
This is a minor patch that really improve compatibility checks
for scripts.
Could be backported in haproxy version as far as 2.0.
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.
Only one event is possible for a spoe-message section. If defined several
time, only the last one is considered. The documentation is now explicit on
this point.
This patch is related to the the issue #1351.
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.

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.
Another non-trivial part that is often needed. Exported functions
and flags available to applications were documented as well as some
restrictions and falltraps.

The "show proc" output changed and it's time to update the example.
The output does not display the relative PID anymore since the nbproc
keyword disappeared, and it displays the number of failed reloads since
the last successful one.
In HTTP, when a lua action is evaluated, a reply object can be used to send
a response to the client and interrupt the transaction. This reply object is
converted into HTX and is limited to the response channel buffer. Its size,
once converted, cannot exceed the buffer size. There is no streaming at this
stage. However, this limitation was not documented.
Note that, for now, there is no easy way to know if the reply will fit or
not int the response channel buffer. Thus the reply must be reasonably
small. Otherwise a 500-Internal-Error message is returned.
This patch is related to the issue #1447. It may be backported as far as
2.2.
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.
This one was missing. It should be easier to use now. It is obvious that
some functions are missing, and it looks like ist2str() and istpad() are
exactly the same.

- 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.
It's not always easy to figure that there are some docs on internal API
stuff, let's move them to their own directory. There's a diagram for
lists that could be placed there but instead would deserve a greppable
description for quick lookups, so it was not moved there.
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.
Enable the 'slowstart' keyword for dynamic servers. The slowstart task
is allocated in 'add server' handler if slowstart is used.
As the server is created in disabled state, there is no need to start
the task. The slowstart task will be automatically started on the first
'enable server' invocation.
Allow to use the check related keywords defined in server.c. These
keywords can be enabled now that checks have been implemented for
dynamic servers.
Here is the list of the new keywords supported :
- error-limit
- observe
- on-error
- on-marked-down
- on-marked-up
Allow to configure ssl support for dynamic server checks independently
of the ssl server configuration. This is done via the keyword
"check-ssl". Also enable to configure the sni/alpn used for the check
via "check-sni/alpn".
A lot of people encounter problems when trying to inject a certificate
file which contains extra informations or empty lines.
This patch adds a paragraph and a sanitizing example.
Must be backported as far as 2.1.

When setting variables, there are currently two variants, one which will
always create the variable, and another one, "ifexist", which will only
create or update a variable if a similarly named variable in any scope
already existed before.
The goal was to limit the risk of injecting random names in the proc
scope, but it was achieved by making use of the somewhat limited name
indexing model, which explains the scope-agnostic restriction.
With this change, we're moving the check downwards in the chain, at the
variable level, and only variables under the scope "proc" will be subject
to the restriction. A new set of VF_* flags was added to adjust how
variables are set, and VF_UPDATEONLY is used to mention this restriction.
In this exact state of affairs, this is not completely exact, as if a
similar name was not known in any scope, the variable will continue to
be rejected like before, but this will change soon.
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.
Most often "set var" on the CLI is used to set a string, and using only
expressions is not always convenient, particularly when trying to
concatenate variables sur as host names and paths.
Now the "set var" command supports an optional keyword before the value
to indicate its type. "expr" takes an expression just like before this
patch, and "fmt" a format string, making it work like the "set-var-fmt"
actions.
The VTC was updated to include a test on the format string.
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.
Relax the condition on "delete server" CLI handler to be able to remove
all servers, even non dynamic, except if they are flagged as non
purgeable.
This change is necessary to extend the use cases for dynamic servers
with reload. It's expected that each dynamic server created via the CLI
is manually commited in the haproxy configuration by the user. Dynamic
servers will be present on reload only if they are present in the
configuration file. This means that non-dynamic servers must be allowed
to be removable at runtime.
The dynamic servers removal reg-test has been updated and renamed to
reflect its purpose. A new test is present to check that non-purgeable
servers cannot be removed.

Lua filter support is highly experimental. The documentation was added to
allow first lua filter implementations. The API is not stabilized and must
be improved to be fully usable. This docuementation is quite light for
now. But more will be added.
First of all, following functions are now considered deprecated:
* Channel:dup()
* Channel:get()
* Channel:getline()
* Channel:get_in_len()
* Cahnnel:get_out_len()
It is just informative, there is no warning and functions may still be
used. Howver it is recommended to use new functions. New functions are more
flexible and use a better naming pattern. In addition, the same names will
be used in the http_msg class to manipulate http messages from lua filters.
The new API is:
* Channel:data()
* Channel:line()
* Channel:append()
* Channel:prepend()
* Channel:insert()
* Channel:remove()
* Channel:set()
* Channel:input()
* Channel:output()
* Channel:send()
* Channel:forward()
* Channel:is_resp()
* Channel:is_full()
* Channel:may_recv()
The lua documentation was updated accordingly.
This commit is the counterpart for agent check of
"MEDIUM: server: implement check for dynamic servers".
The "agent-check" keyword is enabled for dynamic servers. The agent
check must manually be activated via "enable agent" CLI. This can
enable the dynamic server if the agent response is "ready" without an
explicit "enable server" CLI.
Implement check support for dynamic servers. The "check" keyword is now
enabled for dynamic servers. If used, the server check is initialized
and the check task started in the "add server" CLI handler. The check is
explicitely disabled and must be manually activated via "enable health"
CLI handler.
The dynamic server refcount is incremented if a check is configured. On
"delete server" handler, the check is purged, which decrements the
refcount.
Right now we're using a DWCAS to atomically set the running_mask while
being constrained by the thread_mask. This DWCAS is annoying because we
may seriously need it later when adding support for thread groups, for
checking that the running_mask applies to the correct group.
It turns out that the DWCAS is not strictly necessary because we never
need it to set the thread_mask based on the running_mask, only the other
way around. And in fact, the running_mask is always cleared alone, and
the thread_mask is changed alone as well. The running_mask is only
relevant to indicate a takeover when the thread_mask matches it. Any
bit set in running and not present in thread_mask indicates a transition
in progress.
As such, it is possible to re-arrange this by using a regular CAS around a
consistency check between running_mask and thread_mask in fd_update_events
and by making a CAS on running_mask then an atomic store on the thread_mask
in fd_takeover(). The only other case is fd_delete() but that one already
sets the running_mask before clearing the thread_mask, which is compatible
with the consistency check above.
This change has happily survived 10 billion takeovers on a 16-thread
machine at 800k requests/s.
The fd-migration doc was updated to reflect this change.
Rename the 'dontloglegacyconnerr' option to 'log-error-via-logformat'
which is much more self-explanatory and readable.
Note: only legacy keywords don't use hyphens, it is recommended to
separate words with them in new keywords.

This explains the traps to avoid and the sequence that leads to
consistent use of an FD known by multiple threads at once. This
was co-authored with Olivier.
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.

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
Allow the usage of the 'track' keyword for dynamic servers. On server
deletion, the server is properly removed from the tracking chain to
prevents NULL pointer dereferencing.
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
