Sets OpenSSL 1.1.1's SSL_OP_PRIORITIZE_CHACHA unconditionally, as per [1]:
When SSL_OP_CIPHER_SERVER_PREFERENCE is set, temporarily reprioritize
ChaCha20-Poly1305 ciphers to the top of the server cipher list if a
ChaCha20-Poly1305 cipher is at the top of the client cipher list. This
helps those clients (e.g. mobile) use ChaCha20-Poly1305 if that cipher
is anywhere in the server cipher list; but still allows other clients to
use AES and other ciphers. Requires SSL_OP_CIPHER_SERVER_PREFERENCE.

RFC 7234 says:
A cache MUST NOT store a response to any request, unless:
[...] the Authorization header field (see Section 4.2 of [RFC7235]) does
not appear in the request, if the cache is shared, unless the
response explicitly allows it (see Section 3.2), [...]
In this patch we completely disable the cache upon the receipt of an
Authorization header in the request. In this case it's not possible to
either use the cache or store into the cache anymore.
Thanks to Adam Eijdenberg of Digital Transformation Agency for raising
this issue.
This patch must be backported to 1.8.
For large farms where servers are regularly added or removed, picking
a random server from the pool can ensure faster load transitions than
when using round-robin and less traffic surges on the newly added
servers than when using leastconn.
This commit introduces "balance random". It internally uses a random as
the key to the consistent hashing mechanism, thus all features available
in consistent hashing such as weights and bounded load via hash-balance-
factor are usable. It is extremely convenient because one common concern
when using random is what happens when a server is hammered a bit too
much. Here that can trivially be avoided, like in the configuration below :
backend bk0
balance random
hash-balance-factor 110
server-template s 1-100 127.0.0.1:8000 check inter 1s
Note that while "balance random" internally relies on a hash algorithm,
it holds the same properties as round-robin and as such is compatible with
reusing an existing server connection with "option prefer-last-server".
This converter supplements the existing string matching by allowing
strings to be converted to a variable.
Example usage:
http-request set-var(txn.host) hdr(host)
# Check whether the client is attempting domain fronting.
acl ssl_sni_http_host_match ssl_fc_sni,strcmp(txn.host) eq 0
Export localpeer as the environment variable $HAPROXY_LOCALPEER,
allowing to use this variable in the configuration file.
It's useful to use this variable in the case of synchronized
configuration between peers.
Patch adds ability to fetch frontend's default backend name in your
logic, so it can be used later to derive other backend names to make routing
decisions.
This patch add option crc32c (PP2_TYPE_CRC32C) to proxy protocol v2.
It compute the checksum of proxy protocol v2 header as describe in
"doc/proxy-protocol.txt".
Automatic downgrade of DNS accepted payload size may have undesired side
effect, which could make a backend with all servers DOWN.
After talking with Lukas on the ML, I realized this "feature" introduces
more issues that it fixes problem.
The "best" way to handle properly big responses will be to implement DNS
over TCP.
To be backported to 1.8.
>From the very first day of force-persist and ignore-persist features,
they only applied to backends, except that the documentation stated it
could also be applied to frontends.
In order to make it clear, the documentation is updated and the parser
will raise a warning if the keywords are used in a frontend section.
This patch should be backported up to the 1.5 branch.
This patch implement proxy protocol v2 options related to crypto information:
ssl-cipher (PP2_SUBTYPE_SSL_CIPHER), cert-sig (PP2_SUBTYPE_SSL_SIG_ALG) and
cert-key (PP2_SUBTYPE_SSL_KEY_ALG).
Returns true when the back connection was made over an SSL/TLS transport
layer and the newly created SSL session was resumed using a cached
session or a TLS ticket.
It's always a pain not to be able to combine variables. This commit
introduces the "concat" converter, which appends a delimiter, a variable's
contents and another delimiter to an existing string. The result is a string.
This makes it easier to build composite variables made of other variables.
Proxy protocol v2 can transport many optional informations. To avoid
send-proxy-v2-* explosion, this patch introduce proxy-v2-options parameter
and will allow to write: "send-proxy-v2 proxy-v2-options ssl,cert-cn".
Remove the old suggestion to use http-server-close mode, from the
beginnings of keep-alive mode in commit 16bfb021 "MINOR: config: add
option http-keep-alive").
We made http-keep-alive default in commit 70dffdaa "MAJOR: http:
switch to keep-alive mode by default".
Add an optional second parameter to the ipmask converter that specifies
the number of bits to mask off IPv6 addresses.
If the second parameter is not given IPv6 addresses fail to mask (resulting
in an empty string), preserving backwards compatibility: Previously
a sample like `src,ipmask(24)` failed to give a result for IPv6 addresses.
This feature can be tested like this:
defaults
log global
mode http
option httplog
option dontlognull
timeout connect 5000
timeout client 50000
timeout server 50000

Add date_us sample that returns the microsecond part of the timeval
structure representing the date of the structure. The "second" part of
the timeval can already be fetched by the "date" sample
Since RFC2616, the following codes were added to the list of codes
cacheable by default : 204, 404, 405, 414, 501. For now this it only
checked by the checkcache option to detect cacheable cookies.
We used to have a rule inherited from RFC2616 saying that the POST
method was the only uncacheable one, but things have changed since
and RFC7231+7234 made it clear that in fact only GET/HEAD/OPTIONS/TRACE
are cacheable. Currently this rule is only used to detect cacheable
cookies.
This converter was recently introduced by commit ed0d24e ("MINOR:
sample: add len converter").
As found by Cyril, it causes an issue in "http-request capture"
statements. The non-obvious problem is that an old syntax for sample
expressions and converters used to support a series of words, each
representing a converter. This used to be how the "stick" directives
were created initially. By having a converter called "len", a
statement such as "http-request capture foo len 10" considers "len"
as a converter and not as the capture length.
This obsolete syntax needs to be changed in 1.9 but it's too late
for other versions. It's worth noting that the same problem can
happen if converters are registered on the fly using Lua. Other
language keywords that currently have to be avoided in converters
include "id", "table", "if", "unless".
"monitor-uri" may rely on "monitor fail" rules, which are processed
very early, immediately after the HTTP request is parsed and before
any http rulesets. It's not reported by the config parser when this
ruleset is misplaces, causing some configurations not to work like
users would expect. Let's just add the warning for a misplaced rule.
Cache sections were not defined as the others, preventing them to be
correctly parsed by the HTML converter. Also, the "Cache" subsections
where not added to the summary.
This patch should be backported to the 1.8 branch.

This patch changes the behavior of the master during the exit of a
worker.
When a worker exits with an error code, for example in the case of a
segfault, all workers are now killed and the master leaves.
If you don't want this behavior you can use the option
"master-worker no-exit-on-failure".
It is now possible on a "bind" line (or a "stats socket" line) to specify the
thread set allowed to process listener's connections. For instance:
# HTTPS connections will be processed by all threads but the first and HTTP
# connection will be processed on the first thread.
bind *:80 process 1/1
bind *:443 ssl crt mycert.pem process 1/2-
Now, it is possible to bind CPU at the thread level instead of the process level
by defining a thread set in "cpu-map" directives. Thus, its format is now:
cpu-map [auto:]<process-set>[/<thread-set>] <cpu-set>...
where <process-set> and <thread-set> must follow the format:
all | odd | even | number[-[number]]
Having a process range and a thread range in same time with the "auto:" prefix
is not supported. Only one range is supported, the other one must be a fixed
number. But it is allowed when there is no "auto:" prefix.
Because it is possible to define a mapping for a process and another for a
thread on this process, threads will be bound on the intersection of their
mapping and the one of the process on which they are attached. If the
intersection is null, no specific binding will be set for the threads.
It was a temporary directive used for development purpose. Now, CPU mapping for
at the thread level should be done using the cpu-map directive. This feature
will be added in a next commit.
Now, processa and CPU ranges can be partially defined. The higher bound can be
omitted. In such case, it is replaced by the corresponding maximum value, 32 or
64 depending on the machine's word size.
By extension, It is also true for the "bind-process" directive and "process"
parameter on a "bind" or a "stats socket" line.
The prefix "auto:" can be added before the process set to let HAProxy
automatically bind a process to a CPU by incrementing process and CPU sets. To
be valid, both sets must have the same size. No matter the declaration order of
the CPU sets, it will be bound from the lower to the higher bound.
Examples:
# all these lines bind the process 1 to the cpu 0, the process 2 to cpu 1
# and so on.
cpu-map auto:1-4 0-3
cpu-map auto:1-4 0-1 2-3
cpu-map auto:1-4 3 2 1 0
# bind each process to exaclty one CPU using all/odd/even keyword
cpu-map auto:all 0-63
cpu-map auto:even 0-31
cpu-map auto:odd 32-63
# invalid cpu-map because process and CPU sets have different sizes.
cpu-map auto:1-4 0 # invalid
cpu-map auto:1 0-3 # invalid
Now, you can define processes concerned by a cpu-map line using a range. For
instance, the following line binds the first 32 processes on CPUs 0 to 3:
cpu-map 1-32 0-3
HTTP/2 mandates the support of 16384 bytes frames by default, so we need
a large enough buffer to process them. Till now if tune.bufsize was too
small, H2 connections were simply rejected during their establishment,
making it quite hard to troubleshoot the issue.
Now we detect when HTTP/2 is enabled on an HTTP frontend and emit an
error if tune.bufsize is not large enough, with the appropriate
recommendation.
At the moment, the "client" timeout is used on an HTTP/2 connection once
it's idle with no active stream. With this patch, this timeout is replaced
by client-fin once a GOAWAY frame is sent. This closely matches what is
done on HTTP/1 since the principle is the same, as it indicates a willing
ness to quickly close a connection on which we don't expect to see anything
anymore.
This one acts similarly to its tcp-request counterpart. It immediately
closes the request without emitting any response. It can be suitable in
certain DoS conditions, as well as to close an HTTP/2 connection.
Since we switched to notify mode in the systemd unit file in commit
d6942c8, haproxy won't start if the daemon keyword is present in the
configuration.
This change makes sure that haproxy remains in foreground when using
systemd mode and adds a note in the documentation.
