The new "update ssl ocsp-response <certfile>" CLI command allows to
update the stored OCSP response for a given certificate. It relies on
the http_client which is used to send an HTTP request to the OCSP
responder whose URI can be extracted from the certificate.
This command won't work for a certificate that did not have a stored
OCSP response yet.
Till now it was only possible to change the thread local hot cache size
at build time using CONFIG_HAP_POOL_CACHE_SIZE. But along benchmarks it
was sometimes noticed a huge contention in the lower level memory
allocators indicating that larger caches could be beneficial, especially
on machines with large L2 CPUs.
Given that the checks against this value was no longer on a hot path
anymore, there was no reason for continuing to force it to be tuned at
build time. So this patch allows to set it by tune.memory-hot-size.
It's worth noting that during the boot phase the value remains zero so
that it's possible to know if the value was set or not, which opens the
possibility that we try to automatically adjust it based on the per-cpu
L2 cache size or the use of certain protocols (none of this is done yet).
Since the massive pools cleanup that happened in 2.6, the pools
architecture was made quite more hierarchical and many alternate code
blocks could be moved to runtime flags set by -dM. One of them had not
been converted by then, DEBUG_UAF. It's not much more difficult actually,
since it only acts on a pair of functions indirection on the slow path
(OS-level allocator) and a default setting for the cache activation.
This patch adds the "uaf" setting to the options permitted in -dM so
that it now becomes possible to set or unset UAF at boot time without
recompiling. This is particularly convenient, because every 3 months on
average, developers ask a user to recompile haproxy with DEBUG_UAF to
understand a bug. Now it will not be needed anymore, instead the user
will only have to disable pools and enable uaf using -dMuaf. Note that
-dMuaf only disables previously enabled pools, but it remains possible
to re-enable caching by specifying the cache after, like -dMuaf,cache.
A few tests with this mode show that it can be an interesting combination
which catches significantly less UAF but will do so with much less
overhead, so it might be compatible with some high-traffic deployments.
The change is very small and isolated. It could be helpful to backport
this at least to 2.7 once confirmed not to cause build issues on exotic
systems, and even to 2.6 a bit later as this has proven to be useful
over time, and could be even more if it did not require a rebuild. If
a backport is desired, the following patches are needed as well:
CLEANUP: pools: move the write before free to the uaf-only function
CLEANUP: pool: only include pool-os from pool.c not pool.h
REORG: pool: move all the OS specific code to pool-os.h
CLEANUP: pools: get rid of CONFIG_HAP_POOLS
DEBUG: pool: show a few examples in -dMhelp
Activate QUIC connection socket to achieve the best performance. The
previous behavior can be reverted by tune.quic.socket-owner
configuration option.
This change is part of quic-conn owned socket implementation.
Contrary to its siblings patches, I suggest to not backport it to 2.7.
This should ensure that stable releases behavior is perserved. If a user
faces issues with QUIC performance on 2.7, he can nonetheless change the
default configuration.
Define global configuration option "tune.quic.socket-owner". This option
can be used to activate or not socket per QUIC connection mode. The
default value is "listener" which disable this feature. It can be
activated with the option "connection".
This change is part of quic-conn owned socket implementation.
It may be backported to 2.7 after a period of observation.
This is an initial work for the dedicated
event handler API internal documentation.
The file is located at doc/internals/api/event_hdl.txt
event_hdl feature has been introduced with:
MINOR: event_hdl: add event handler base api
This patch also adds a set of new global options:
- 51degrees-use-performance-graph { on | off }
- 51degrees-use-predictive-graph { on | off }
- 51degrees-drift <number>
- 51degrees-difference <number>
- 51degrees-allow-unmatched { on | off }
To build using the latest 51Degrees V4 engine with Hash algorithm, set
USE_51DEGREES_V4=1.
Other supported build options are 51DEGREES_INC, 51DEGREES_LIB and
51DEGREES_SRC which needs to be set to the directory that contains
headers and C files. For example:
make TARGET=<target> USE_51DEGREES_V4=1 51DEGREES_SRC='51D_REPO_PATH'/src

Stick-tables support sharding to multiple peers but there was no way to
know to what shard an entry was going to be sent. Let's display this in
the "show table" output to ease debugging.
There's regularly some confusion about them (do they match at the
beginning, end ? do they support multiple components etc). Tim
suggested to improve the doc in issue #61, it's never too late, so
let's do it now wih a few examples.
In issue #412 it was rightfully reported that the wording in "retries"
still exclusively speaks about connection attempts, while since L7
retries with "retry-on" it's no longer a limitation. Let's update the
text.
In issue #698, it's made apparent that the default matching method for
ACL keywords can be confusing when a converter is applied, because
depending on the converters used, users may think that the default
matching method from the sample fetch name might apply to the whole
expression. It's easier to understand that this doesn't make sense
when thinking about converters turning to completely different types
(e.g. hdr_beg(host),do_resolve() returns an IP, thus it's obvious
that _beg makes no sense at all). This patch states this in the
doc to avoid future confusion.
It was reported in issue #1059 that when multiple monitor-uri rules are
specified, only the last one is used. While this was done on purpose
since a single URI is used, it was not clearly mentioned in the doc,
possibly leading to confusion or wasted time trying to establish a
working setup. Let's clarify this point.
As reported by Tim in issue #1373 some warnings are deserved to explain
why using the frontend SNI for routing or connecting to a server is
usually not correct, especially since it can be tempting and used to
make sense in pure TCP scenarios.
As requested by Nick in issue #1719, let's add a reference to the section
about quoting there, since add_item() will often be used with commas and
it's easy to mess up.
This adds some configuration hints regarding various workloads that do
not manage to achieve high reuse rates due to too low a global maxconn
or thread groups.
This fixes github issue #1472.

An extra ',' was mistakenly added in table_idle converter signature
with commit ed36968 ("DOC: configuration.txt: add default_value for
table_idle signature").
table_idle converter takes optional default_value argument.
The documentation correctly describes this usage but <default_value> was
missing in the converter signature.
It should be backported with bbeec37b3 ("MINOR: stick-table:
Add table_expire() and table_idle() new converters")
An abosulte URI is marked as normalized if it comes from an H2 client. This
way, we know we can send a relative URI to an H1 server. But, after a
set-uri action, the URI must no longer be considered as normalized.
Otherwise there is no way to send an absolute URI on the server side.
If it is important to update a normalized absolute URI without altering this
property, the host, path and/or query-string must be set separatly.
This patch should fix the issue #1938. It should be backported as far as
2.4.
Complete quic4/quic6 bind lines by a note on performance issues due to
receiver socket contention. Suggest to use sharding to improve the
situation.
This should be backported up to 2.6.
If no cluster-secret is defined by the user, a random one is silently
generated.
This ensures that at least QUIC Retry tokens are generated if abnormal
conditions are detected. However, it is advisable to specify it in the
configuration for tokens to be valid even after a reload or across LBs
instances in the same cluster.
This should be backported up to 2.6.
QUIC Retry generation relies on global cluster-secret to produce token
valid even after a process restart and across several LBs instances.
Before this patch, Retry is automatically deactivated if no
cluster-secret is provided. This is the case even if a user has
configured a QUIC listener with quic-force-retry. Change this behavior
by now returning an error during configuration parsing. The user must
provide a cluster-secret if quic-force-retry is used.
This shoud be backported up to 2.6.
The "show pools" command is used a lot for debugging but didn't get much
love over the years. This patch brings new capabilities:
- sorting the output by pool names to ese their finding ("byname").
- sorting the output by reverse item size to spot the biggest ones("bysize")
- sorting the output by reverse number of allocated bytes ("byusage")
The last one (byusage) also omits displaying the ones with zero allocation.
In addition, an optional max number of output entries may be passed so as
to dump only the N most relevant ones.
The silent-drop action was extended with an additional optional parameter,
[rst-ttl <ttl> ], causing HAProxy to send a TCP RST with the specified TTL
towards the client.
With this behaviour, the connection state on your own client-
facing middle-boxes (load balancers, firewalls) will be purged,
but the client will still assume the TCP connection is up because
the TCP RST packet expires before reaching the client.

Let's keep these notes as references for later use. Polling on connect()
can sometimes return a few unexpected state combinations that such tests
illustrate. They can serve as reminders for special error handling.
The exact same commands as those from the CLI may be pre-loaded at boot
time by passing them one per line after the "trace" keyword in the global
section; i.e. just copy-pasting all commands directly there will do the
job. Note that if a ring is mentioned, it needs to be declared before the
global section. Another option is to append another global section after
"ring".
For now the keyword is marked as experimental to discourage its broad
adoption by default. "expose-experimental-directives" needs to be placed
in the global section to expose it.
the global section keywords were seriously misordered, and it's visible
that some mistakes have induced other ones over time, so it was about
time to fix this. Roughly 20% of the keywords were misplaced.
This commit only reordered the keywords index and their description,
nothing else was changed. It might be backported because it's a real
pain to find certain options there.
Once in a while we spot a bug in the deinit code that is complex,
especially when it has to deal with incomplete initializations, and the
ability to bypass this step has regularly been raised. In addition for
fast-reloading setups it could theoretically save some time. Tests have
shown that very large configs can barely save ~100-150ms by skipping the
deinit step. However the ability not to crash if a bug is encountered can
occasionally help.
This patch adds an option to do exactly this. It's obviously not enabled
by default and the documentation discourages from using it, but this might
be useful in the future.
The ca-ignore-err and crt-ignore-err directives are now able to use the
openssl X509_V_ERR constant names instead of the numerical values.
This allow a configuration to survive an OpenSSL upgrade, because the
numerical ID can change between versions. For example
X509_V_ERR_INVALID_CA was 24 in OpenSSL 1 and is 79 in OpenSSL 3.
The list of errors must be updated when a new major OpenSSL version is
released.
Add "shards" new keyword for "peers" section to configure the number
of peer shards attached to such secions. This impact all the stick-tables
attached to the section.
Add "shard" new "server" parameter to configure the peers which participate to
all the stick-tables contents distribution. Each peer receive the stick-tables updates
only for keys with this shard value as distribution hash. The "shard" value
is stored in ->shard new server struct member.
cfg_parse_peers() which is the function which is called to parse all
the lines of a "peers" section is modified to parse the "shards" parameter
stored in ->nb_shards new peers struct member.
Add srv_parse_shard() new callback into server.c to pare the "shard"
parameter.
Implement stksess_getkey_hash() to compute the distribution hash for a
stick-table key as the 64-bits xxhash of the key concatenated to the stick-table
name. This function is called by stksess_setkey_shard(), itself
called by the already implemented function which create a new stick-table
key (stksess_new()).
Add ->idlen new stktable struct member to store the stick-table name length
to not have to compute it each time a stick-table key hash is computed.

Adding a legacy link to get old toolbox source code as well as
a link to luarocks that seems to have superseded it.
