"log-balance" directive was recently introduced to configure the
balancing algorithm to use when in a log backend. However, it is
confusing and it causes issues when used in default section.
In this patch, we take another approach: first we remove the
"log-balance" directive, and instead we rely on existing "balance"
directive to configure log load balancing in log backend.
Some algorithms such as roundrobin can be used as-is in a log backend,
and for log-only algorithms, they are implemented as "log-$name" inside
the "backend" directive.
The documentation was updated accordingly.
This one reports streams considered as "suspicious", i.e. those with
no expiration dates or dates in the past, or those without a front
endpoint. More criteria could be added in the future.
It's often needed to be able to refine "show sess" when debugging, and
very often a first glance at old streams is performed, but that's a
difficult task in large dumps, and it takes lots of resources to dump
everything.
This commit adds "older <age>" to "show sess" in order to specify the
minimum age of streams that will be dumped. This should simplify the
identification of blocked ones.
Document the "handshake" timeout new setting available one frontend side.
This should at least be helpful for QUIC client connections to prevent
an attacker from refreshing plenty of connections without completing
the handshake step, leading haproxy to consume memory for nothing.
"disable-" prefix was missing. This param was correctly named in the list of
supported keywords in the global section, but not in the keyword
description.
No backport needed.
User @nwehrman reported in issue #2328 that the used of "proxy" instead
of "backend" in the argument of the "track" server keyword is confusing.
Admittedly, all other places in the doc use "backend/server" instead of
"proxy/server", so let's update it for the sake of consistency.
QUIC connections are pushed manually into a dedicated listener queue
when they are ready to be accepted. This happens after handshake
finalization or on 0-RTT packet reception. Listener is then woken up to
dequeue them with listener_accept().
This patch comptabilizes the number of connections currently stored in
the accept queue. If reaching a certain limit, INITIAL packets are
dropped on reception to prevent further QUIC connections allocation.
This should help to preserve system resources.
This limit is automatically derived from the listener backlog. Half of
its value is reserved for handshakes and the other half for accept
queues. By default, backlog is equal to maxconn which guarantee that
there can't be no more than maxconn connections in handshake or waiting
to be accepted.
Implement a limit per listener for concurrent number of QUIC
connections. When reached, INITIAL packets for new connections are
automatically dropped until the number of handshakes is reduced.
The limit value is automatically based on listener backlog, which itself
defaults to maxconn.
This feature is important to ensure CPU and memory resources are not
consume if too many handshakes attempt are started in parallel.
Special care is taken if a connection is released before handshake
completion. In this case, counter must be decremented. This forces to
ensure that member <qc.state> is set early in qc_new_conn() before any
quic_conn_release() invocation.
The documentation about -q seems wrong, it does not output messages
after the startup, it disables all messages. It was always quiet with
the stdio_quiet() function.
Must be backported in all stable versions.

To follow-up the implementation of the new set-proxy-v2-tlv-fmt
keyword in the server, the connection is updated to use the previously
allocated TLVs. If no value was specified, we send out an empty TLV.
As the feature is fully working with this commit, documentation and a
test for the server and default-server are added as well.
In this patch, we add the possibility to declare on a table definition
("table" in peer section, or "stick-table" in proxy section) that we
want the remote/peer updates on that table to be pushed on a local
haproxy table in addition to the source table.
Consider this example:
|peers mypeers
| peer local 127.0.0.1:3334
| peer clust 127.0.0.1:3333
| table t1.local type string size 10m store server_id,server_key expire 30s
| table t1.clust type string size 10m store server_id,server_key write-to mypeers/t1.local expire 30s
With this setup, we consider haproxy uses t1.local as cache/local table
for read and write operations, and that t1.clust is a remote table
containing datas processed from t1.local and similar tables from other
haproxy peers in a cluster setup. The t1.clust table will be used to
refresh the local/cache one via the "write-to" statement.
What will happen, is that every time haproxy will see entry updates for
the t1.clust table: it will overwrite t1.local table with fresh data and
will update the entry expiration timer. If t1.local entry doesn't exist
yet (key doesn't exist), it will automatically create it. Note that only
types that cannot be used for arithmetic ops will be handled, and this
to prevent processed values from the remote table from interfering with
computations based on values from the local table. (ie: prevent
cumulative counters from growing indefinitely).
"write-to" will only push supported types if they both exist in the source
and the target table. Be careful with server_id and server_key storage
because they are often declared implicitly when referencing a table in
sticking rules but it is required to declare them explicitly for them to
be pushed between a remote and a local table through "write-to" option.
Also note that the "write-to" target table should have the same type as
the source one, and that the key length should be strictly equal,
otherwise haproxy will raise an error due to the tables being
incompatibles. A table that is already being written to cannot be used
as a source table for a "write-to" target.
Thanks to this patch, it will now be possible to use sticking rules in
peer cluster context by using a local table as a local cache which
will be automatically refreshed by one or multiple remote table(s).
This commit depends on:
- "MINOR: stktable: stktable_init() sets err_msg on error"
- "MINOR: stktable: check if a type should be used as-is"
This new fetcher can be used to extract the list of cookie names from
Cookie request header or from Set-Cookie response header depending on
the stream direction. There is an optional argument that can be used
as the delimiter (which is assumed to be the first character of the
argument) between cookie names. The default delimiter is comma (,).
Note that we will treat the Cookie request header as a semi-colon
separated list of cookies and each Set-Cookie response header as
a single cookie and extract the cookie names accordingly.
After making it configurable in previous commit "MINOR: lua: Add flags
to configure logging behaviour", this patch changes the default value
of tune.lua.log.stderr from 'on' (unconditionally forward LUA logs to
stderr) to 'auto' (only forward LUA logs to stderr if logging via a
standard logger is disabled, or none is configured for the current context)
Since this is a change in behaviour, it shouldn't be backported
Until now, messages printed from LUA log functions were sent both to
the any logger configured for the current proxy, and additionally to
stderr (in most cases)
This introduces two flags to configure LUA log handling:
- tune.lua.log.loggers to use standard loggers or not
- tune.lua.log.stderr to use stderr, or not, or only conditionally
This addresses github feature request #2316
This can be backported to 2.8 as it doesn't change previous behaviour.

Method now returns the content of Json Arrays, if it is specified in
Json Path as String. The start and end character is a square bracket. Any
complex object in the array is returned as Json, so that you might get Arrays
of Array or objects. Only recommended for Arrays of simple types (e.g.,
String or int) which will be returned as CSV String. Also updated
documentation and fixed issue with parenthesis and other changes from
comments.
This patch was discussed in issue #2281.

Previously, maxconn keyword was reused for a specific usage on reverse
HTTP binds to specify the number of active connect to proceed. To avoid
confusion, introduce a new dedicated keyword 'nbconn' which is specific
to reverse HTTP bind.
This new keyword is forbidden for non-reverse listener. A fatal error is
emitted during config parsing if this rule is not respected. It's safe
because it's also forbidden to mix standard and reverse addresses on the
same bind line.
Internally, nbconn value will be reassigned to 'maxconn' member of
bind_conf structure. This ensures that listener layer will automatically
reenable the preconnect task each time a connection is closed.
tune.rcvbuf.client and tune.rcvbuf.server are not suitable for shared
dgram sockets because they're per connection so their units are not the
same. However, QUIC's listener and log servers are not connected and
take per-thread or per-process traffic where a socket log buffer might
be too small, causing undesirable packet losses and retransmits in the
case of QUIC. This essentially manifests in listener mode with new
connections taking a lot of time to set up under heavy traffic due to
the small queues causing delays. Let's add a few new settings allowing
to set these shared socket sizes on the frontend and backend side (which
reminds that these are per-front/back and not per client/server hence
not per connection).
The zero-copy forwarding or the mux-to-mux forwarding is a way to
fast-forward data without using the channels buffers. Data are transferred
from a mux to the other one. The kernel splicing is an optimization of the
zero-copy forwarding. But it can also use normal buffers (but not channels
ones). This way, it could be possible to fast-forward data with muxes not
supporting the kernel splicing (H2 and H3 muxes) but also with applets.
However, this mode can introduce regressions or bugs in future (just like
the kernel splicing). Thus, It could be usefull to disable this optim. To do
so, in configuration, the global tune settting
'tune.disable-zero-copy-forwarding' may be set in a global section or the
'-dZ' command line parameter may be used to start HAProxy. Of course, this
also disables the kernel splicing.
"log-bufsize" may now be used for a log server (in a log backend) to
configure the bufsize of implicit ring associated to the server (which
defaults to BUFSIZE).
hash lb algorithm can be configured with the "log-balance hash <cnv_list>"
directive. With this algorithm, the user specifies a converter list with
<cnv_list>.
The produced log message will be passed as-is to the provided converter
list, and the resulting hash will be used to select the log server that
will receive the log message.
Allow the use of the "none" hash-type function so that the key resulting
from the sample expression is directly used as the hash.
This can be useful to do the hashing manually using available hashing
converters, or even custom ones, and then inform haproxy that it can
directly rely on the sample expression result which is explictly handled
as an integer in this case.
In this patch we add basic support for the random algorithm:
random algorithm picks a random server using the result of the
statistical_prng() function as if it was a hash key to then compute the
related server ID.
There is no support for the <draw> parameter (which is implemented for
tcp/http load-balancing), because we don't have the required metrics to
evaluate server's load in log backends for the moment. Plus it would add
more complexity to the __do_send_log_backend() function so we'll keep it
this way for now but this might be needed in the future.
sticky algorithm always tries to send log messages to the first server in
the farm. The server will stay in front during queue and dequeue
operations (no other server can steal its place), unless it becomes
unavailable, in which case it will be replaced by another server from
the tree.
Using "mode log" in a backend section turns the proxy in a log backend
which can be used to log-balance logs between multiple log targets
(udp or tcp servers)
log backends can be used as regular log targets using the log directive
with "backend@be_name" prefix, like so:
| log backend@mybackend local0
A log backend will distribute log messages to servers according to the
log load-balancing algorithm that can be set using the "log-balance"
option from the log backend section. For now, only the roundrobin
algorithm is supported and set by default.
This is a follow up of the previous commit to emphasize that "log"
directive allows to provide a log target which may directly be a server
address but may also be a log transport facility such as rings. Thus we
use the term "target" instead of "address" to make it more generic.

"log" directive description was found 2 times in the configuration file:
First, in 3.1 in the "global parameters" chapter, and then in 4.2 in the
per-proxy keyword options.
Both descriptions are almost identical: having to maintain the "same"
documentation in 2 different places is error-prone. Due to this, some
precisions have been added in one of them, and were missing from
the other, and vice-versa, probably because one didn't see that the
"log" directive was also documented elsewhere.
To prevent the 2 descriptions from further diverging, and make it easier
to maintain, we merge them in the per-proxy "log" directive description
(in 4.2 chapter), and we add a pointer to it in the global "log" to
encourage the user to refer to the per-proxy "log" documentation for
usage details.
This patch add a hash of the Origin header to the cache's secondary key.
This enables to manage store responses that have a "Vary: Origin" header
in the cache when vary is enabled.
This cannot be considered as a means to manage CORS requests though, it
only processes the Origin header and hashes the presented value without
any form of URI normalization.
This need was expressed by Philipp Hossner in GitHub issue #251.

Define a new bind option quic-socket :
quic-socket [ connection | listener ]
This new setting works in conjunction with the existing configuration
global tune.quic.socket-owner and reuse the same semantics.
The purpose of this setting is to allow to disable connection socket
usage on listener instances individually. This will notably be useful
when needing to deactivating it when encountered a fatal permission
error on bind() at runtime.
Added set-timeout for frontend side of session, so it can be used to set
custom per-client timeouts if needed. Added cur_client_timeout to fetch
client timeout samples.

Prior to this commit, converter "bytes" takes only integer values as
arguments. After this commit, it can take variable names as inputs.
This allows us to dynamically determine the offset/length and capture
them in variables. These variables can then be used with the converter.
Example use case: parsing a token present in a request header.
This reverts commit c618ed5ff4.
The list iterator is broken. As found by Fred, running QUIC single-
threaded shows that only the first connection is accepted because the
accepter relies on the element being initialized once detached (which
is expected and matches what MT_LIST_DELETE_SAFE() used to do before).
However while doing this in the quic_sock code seems to work, doing it
inside the macro show total breakage and the unit test doesn't work
anymore (random crashes). Thus it looks like the fix is not trivial,
let's roll this back for the time it will take to fix the loop.
The new mt_list code supports exponential back-off on conflict, which
is important for use cases where there is contention on a large number
of threads. The API evolved a little bit and required some updates:
- mt_list_for_each_entry_safe() is now in upper case to explicitly
show that it is a macro, and only uses the back element, doesn't
require a secondary pointer for deletes anymore.
- MT_LIST_DELETE_SAFE() doesn't exist anymore, instead one just has
to set the list iterator to NULL so that it is not re-inserted
into the list and the list is spliced there. One must be careful
because it was usually performed before freeing the element. Now
instead the element must be nulled before the continue/break.
- MT_LIST_LOCK_ELT() and MT_LIST_UNLOCK_ELT() have always been
unclear. They were replaced by mt_list_cut_around() and
mt_list_connect_elem() which more explicitly detach the element
and reconnect it into the list.
- MT_LIST_APPEND_LOCKED() was only in haproxy so it was left as-is
in list.h. It may however possibly benefit from being upstreamed.
This required tiny adaptations to event_hdl.c and quic_sock.c. The
test case was updated and the API doc added. Note that in order to
keep include files small, the struct mt_list definition remains in
list-t.h (par of the internal API) and was ifdef'd out in mt_list.h.
A test on QUIC with both quictls 1.1.1 and wolfssl 5.6.3 on ARM64 with
80 threads shows a drastic reduction of CPU usage thanks to this and
the refined memory barriers. Please note that the CPU usage on OpenSSL
3.0.9 is significantly higher due to the excessive use of atomic ops
by openssl, but 3.1 is only slightly above 1.1.1 though:
- before: 35 Gbps, 3.5 Mpps, 7800% CPU
- after: 41 Gbps, 4.2 Mpps, 2900% CPU

More and more utility functions rely on the trash while most of the init
code doesn't have access to it because it's initialized very late (in
PRE_CHECK for the initial one). It's a pool, and it purposely supports
being reallocated, so let's initialize it in STG_POOL so that early
STG_INIT code can at least use it.
