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.

From first-hand experience I realized that using encrypted passwords in
userlists can quickly become overwhelming for busy sites. In my case
just about 100 rq/s were enough to drive (user) CPU usage from 2-3% up
to >90%. While it is perfectly explicable why this is the case, having

A new sample fetch function reports either 1 or 2 for the on-wire encoding,
to indicate if the request was received using the HTTP/1.x format or HTTP/2
format. Note that it reports the on-wire encoding, not the version presented
in the request header.
This will possibly have to evolve if it becomes necessary to report the
encoding on the server side as well.
By default, no affinity is set for threads. To bind threads on CPU, you must
define a "thread-map" in the global section. The format is the same than the
"cpu-map" parameter, with a small difference. The process number must be
defined, with the same format than cpu-map ("all", "even", "odd" or a number
between 1 and 31/63).
A thread will be bound on the intersection of its mapping and the one of the
process on which it is attached. If the intersection is null, no specific bind
will be set for the thread.
This is a huge patch with many changes, all about the DNS. Initially, the idea
was to update the DNS part to ease the threads support integration. But quickly,
I started to refactor some parts. And after several iterations, it was
impossible for me to commit the different parts atomically. So, instead of
adding tens of patches, often reworking the same parts, it was easier to merge
all my changes in a uniq patch. Here are all changes made on the DNS.
First, the DNS initialization has been refactored. The DNS configuration parsing
remains untouched, in cfgparse.c. But all checks have been moved in a post-check
callback. In the function dns_finalize_config, for each resolvers, the
nameservers configuration is tested and the task used to manage DNS resolutions
is created. The links between the backend's servers and the resolvers are also
created at this step. Here no connection are kept alive. So there is no needs
anymore to reopen them after HAProxy fork. Connections used to send DNS queries
will be opened on demand.
Then, the way DNS requesters are linked to a DNS resolution has been
reworked. The resolution used by a requester is now referenced into the
dns_requester structure and the resolution pointers in server and dns_srvrq
structures have been removed. wait and curr list of requesters, for a DNS
resolution, have been replaced by a uniq list. And Finally, the way a requester
is removed from a DNS resolution has been simplified. Now everything is done in
dns_unlink_resolution.
srv_set_fqdn function has been simplified. Now, there is only 1 way to set the
server's FQDN, independently it is done by the CLI or when a SRV record is
resolved.
The static DNS resolutions pool has been replaced by a dynamoc pool. The part
has been modified by Baptiste Assmann.
The way the DNS resolutions are triggered by the task or by a health-check has
been totally refactored. Now, all timeouts are respected. Especially
hold.valid. The default frequency to wake up a resolvers is now configurable
using "timeout resolve" parameter.
Now, as documented, as long as invalid repsonses are received, we really wait
all name servers responses before retrying.
As far as possible, resources allocated during DNS configuration parsing are
releases when HAProxy is shutdown.
Beside all these changes, the code has been cleaned to ease code review and the
doc has been updated.
This action is used to trigger sending of a group of SPOE messages. To do so,
the SPOE engine used to send messages must be defined, as well as the SPOE group
to send. Of course, the SPOE engine must refer to an existing SPOE filter. If
not engine name is provided on the SPOE filter line, the SPOE agent name must be
used. For example:
http-request send-spoe-group my-engine some-group
This action is available for "tcp-request content", "tcp-response content",
"http-request" and "http-response" rulesets. It cannot be used for tcp
connection/session rulesets because actions for these rulesets cannot yield.
For now, the action keyword is parsed and checked. But it does nothing. Its
processing will be added in another patch.
A bind_conf does contain a ssl_bind_conf, which already has a flag to know
if early data are activated, so use that, instead of adding a new flag in
the ssl_options field.
Add a new sample fetch, "ssl_fc_has_early", a boolean that will be true
if early data were sent, and a new action, "wait-for-handshake", if used,
the request won't be forwarded until the SSL handshake is done.
When compiled with Openssl >= 1.1.1, before attempting to do the handshake,
try to read any early data. If any early data is present, then we'll create
the session, read the data, and handle the request before we're doing the
handshake.
For this, we add a new connection flag, CO_FL_EARLY_SSL_HS, which is not
part of the CO_FL_HANDSHAKE set, allowing to proceed with a session even
before an SSL handshake is completed.
As early data do have security implication, we let the origin server know
the request comes from early data by adding the "Early-Data" header, as
specified in this draft from the HTTP working group :
https://datatracker.ietf.org/doc/html/draft-ietf-httpbis-replay
Use Openssl-1.1.1 SSL_CTX_set_client_hello_cb to mimic BoringSSL early callback.
Native multi certificate and SSL/TLS method per certificate is now supported by
Openssl >= 1.1.1.

- BUG/MINOR: ssl: ocsp response with 'revoked' status is correct
When using haproxy in front of distccd, it's possible to provide significant
improvements by only connecting when the preprocessing is completed, and by
selecting different farms depending on the payload size. This patch provides
two new sample fetch functions :
distcc_param(<token>[,<occ>]) : integer
distcc_body(<token>[,<occ>]) : binary
srv_queue([<backend>/]<server>) : integer
Returns an integer value corresponding to the number of connections currently
pending in the designated server's queue. If <backend> is omitted, then the
server is looked up in the current backend. It can sometimes be used together
with the "use-server" directive to force to use a known faster server when it
is not much loaded. See also the "srv_conn", "avg_queue" and "queue" sample
fetch methods.
Adds cli commands to change at runtime whether informational messages
are prepended with severity level or not, with support for numeric and
worded severity in line with syslog severity level.
Adds stats socket config keyword severity-output to set default behavior
per socket on startup.
smp_fetch_ssl_fc_cl_str as very limited usage (only work with openssl == 1.0.2
compiled with the option enable-ssl-trace). It use internal cipher.algorithm_ssl
attribut and SSL_CIPHER_standard_name (available with ssl-trace).
This patch implement this (debug) function in a standard way. It used common
SSL_CIPHER_get_name to display cipher name. It work with openssl >= 1.0.2
and boringssl.
As per a recent mailing list discussion, suggesting specific cipher
settings is not too helpful, because they depend on a lot of factors,
ranging from client capabilities, available TLS libraries, new
security research, and others.
To avoid the documentation from become stale -- and potentially
wrong/dangerous, this commit adds links to Mozilla's well-reknowned
TLS blog, as well as to their configuration generator.
Following up DNS extension introduction, this patch aims at making the
computation of the maximum number of records in DNS response dynamic.
This computation is based on the announced payload size accepted by
HAProxy.
The "hold obsolete" timer is used to prevent HAProxy from moving a server to
an other IP or from considering the server as DOWN if the IP currently
affected to this server has not been seen for this period of time in DNS
responses.
That said, historically, HAProxy used to update servers as soon as the IP
has disappeared from the response. Current default timeout break this
historical behavior and may change HAProxy's behavior when people will
upgrade to 1.8.
This patch changes the default value to 0 to keep backward compatibility.
Edns extensions may be used to negotiate some settings between a DNS
client and a server.
For now we only use it to announce the maximum response payload size accpeted
by HAProxy.
This size can be set through a configuration parameter in the resolvers
section. If not set, it defaults to 512 bytes.
As DNS servers may not return all IPs in one answer, we want to cache the
previous entries. Those entries are removed when considered obsolete, which
happens when the IP hasn't been returned by the DNS server for a time
defined in the "hold obsolete" parameter of the resolver section. The default
is 30s.
Commit 2ab8867 ("MINOR: ssl: compare server certificate names to the SNI
on outgoing connections") introduced the ability to check server cert
names against the name provided with in the SNI, but verifyhost was kept
as a way to force the name to check against. This was a mistake, because :
- if an SNI is used, any static hostname in verifyhost will be wrong ;
worse, if it matches and doesn't match the SNI, the server presented
the wrong certificate ;
- there's no way to have a default name to check against for health
checks anymore because the point above mandates the removal of the
verifyhost directive
This patch reverses the ordering of the check : whenever SNI is used, the
name provided always has precedence (ie the server must always present a
certificate that matches the requested name). And if no SNI is provided,
then verifyhost is used, and will be configured to match the server's
default certificate name. This will work both when SNI is not used and
for health checks.
If the commit 2ab8867 is backported in 1.7 and/or 1.6, this one must be
backported too.
When support for passing SNI to the server was added in 1.6-dev3, there
was no way to validate that the certificate presented by the server would
really match the name requested in the SNI, which is quite a problem as
it allows other (valid) certificates to be presented instead (when hitting
the wrong server or due to a man in the middle).
This patch adds the missing check against the value passed in the SNI.
The "verifyhost" value keeps precedence if set. If no SNI is used and
no verifyhost directive is specified, then the certificate name is not
checked (this is unchanged).
In order to extract the SNI value, it was necessary to make use of
SSL_SESSION_get0_hostname(), which appeared in openssl 1.1.0. This is
a trivial function which returns the value of s->tlsext_hostname, so
it was provided in the compat layer for older versions. After some
refinements from Emmanuel, it now builds with openssl 1.0.2, openssl
1.1.0 and boringssl. A test file was provided to ease testing all cases.
After some careful observation period it may make sense to backport
this to 1.7 and 1.6 as some users rightfully consider this limitation
as a bug.

We cannot store more than 32K headers in the structure hdr_idx, because
internaly we use signed short integers. To avoid any bugs (due to an integers
overflow), a check has been added on tune.http.maxhdr to be sure to not set a
value greater than 32767 and lower than 1 (because this is a nonsense to set
this parameter to a value <= 0).
The documentation has been updated accordingly.
This patch can be backported in 1.7, 1.6 and 1.5.
The Openssl's ASYNC API does'nt support moving buffers on SSL_read/write
This patch disables the ASYNC mode dynamically when the handshake
is left and re-enables it on reneg.
SSL/TLS version can be changed per certificat if and only if openssl lib support
earlier callback on handshake and, of course, is implemented in haproxy. It's ok
for BoringSSL. For Openssl, version 1.1.1 have such callback and could support it.

This patch is a major upgrade of the internal run-time DNS resolver in
HAProxy and it brings the following 2 main changes:
1. DNS resolution task
Up to now, DNS resolution was triggered by the health check task.
From now, DNS resolution task is autonomous. It is started by HAProxy
right after the scheduler is available and it is woken either when a
network IO occurs for one of its nameserver or when a timeout is
matched.
From now, this means we can enable DNS resolution for a server without
enabling health checking.
2. Introduction of a dns_requester structure
Up to now, DNS resolution was purposely made for resolving server
hostnames.
The idea, is to ensure that any HAProxy internal object should be able
to trigger a DNS resolution. For this purpose, 2 things has to be done:
- clean up the DNS code from the server structure (this was already
quite clean actually) and clean up the server's callbacks from
manipulating too much DNS resolution
- create an agnostic structure which allows linking a DNS resolution
and a requester of any type (using obj_type enum)
3. Manage requesters through queues
Up to now, there was an uniq relationship between a resolution and it's
owner (aka the requester now). It's a shame, because in some cases,
multiple objects may share the same hostname and may benefit from a
resolution being performed by a third party.
This patch introduces the notion of queues, which are basically lists of
either currently running resolution or waiting ones.
The resolutions are now available as a pool, which belongs to the resolvers.
The pool has has a default size of 64 resolutions per resolvers and is
allocated at configuration parsing.
The default len of request uri in log messages is 1024. In some use
cases, you need to keep the long trail of GET parameters. The only
way to increase this len is to recompile with DEFINE=-DREQURI_LEN=2048.
This commit introduces a tune.http.logurilen configuration directive,
allowing to tune this at runtime.
This patch adds the support of a maximum of 32 engines
in async mode.
Some tests have been done using 2 engines simultaneously.
This patch also removes specific 'async' attribute from the connection
structure. All the code relies only on Openssl functions.
ssl-mode-async is a global configuration parameter which enables
asynchronous processing in OPENSSL for all SSL connections haproxy
handles. With SSL_MODE_ASYNC set, TLS I/O operations may indicate a
retry with SSL_ERROR_WANT_ASYNC with this mode set if an asynchronous
capable engine is used to perform cryptographic operations. Currently
async mode only supports one async-capable engine.
This is the latest version of the patchset which includes Emeric's
updates :
- improved async fd cleaning when openssl reports an fd to delete
- prevent conn_fd_handler from calling SSL_{read,write,handshake} until
the async fd is ready, as these operations are very slow and waste CPU
- postpone of SSL_free to ensure the async operation can complete and
does not cause a dereference a released SSL.
- proper removal of async fd from the fdtab and removal of the unused async
flag.
This patch adds the global 'ssl-engine' keyword. First arg is an engine
identifier followed by a list of default_algorithms the engine will
operate.
If the openssl version is too old, an error is reported when the option
is used.
When HAProxy is running with multiple processes and some listeners
arebound to processes, the unused sockets were not closed in the other
processes. The aim was to be able to send those listening sockets using
the -x option.
However to ensure the previous behavior which was to close those
sockets, we provided the "no-unused-socket" global option.
This patch changes this behavior, it will close unused sockets which are
not in the same process as an expose-fd socket, making the
"no-unused-socket" option useless.
The "no-unused-socket" option was removed in this patch.
This patch changes the stats socket rights for allowing the sending of
listening sockets.
The previous behavior was to allow any unix stats socket with admin
level to send sockets. It's not possible anymore, you have to set this
option to activate the socket sending.
Example:
stats socket /var/run/haproxy4.sock mode 666 expose-fd listeners level user process 4
Add "b64dec" as a new converter which can be used to decode a base64
encoded string into its binary representation. It performs the inverse
operation of the "base64" converter.
'ssl-min-ver' and 'ssl-max-ver' with argument SSLv3, TLSv1.0, TLSv1.1, TLSv1.2
or TLSv1.3 limit the SSL negotiation version to a continuous range. ssl-min-ver
and ssl-max-ver should be used in replacement of no-tls* and no-sslv3. Warning
and documentation are set accordingly.
Plan is to add min-tlsxx max-tlsxx configuration, more consistent than no-tlsxx.
min-tlsxx and max-tlsxx can be overwrite on local definition. This directives
should be the only ones needed in default-server.
To simplify next patches (rework of tls versions settings with min/max) all
ssl/tls version settings relative to default-server are reverted first:
remove: 'sslv3', 'tls*', 'no-force-sslv3', 'no-force-tls*'.
remove from default-server: 'no-sslv3', 'no-tls*'.
Note:
. force-tlsxx == min-tlsxx + max-tlsxx : would be ok in default-server.
. no-tlsxx is keep for compatibility: should not be propagated to default-server.
The sample fetch returns all headers including the last jump line.
The last jump line is used to determine if the block of headers is
truncated or not.
Idea from Aleksandar Lazic: add explanation/links about layer4
tcp-request connection or content reject to "block" keyword.
Add http-request cross ref. to "tcp-request content".
When running with multiple process, if some proxies are just assigned
to some processes, the other processes will just close the file descriptors
for the listening sockets. However, we may still have to provide those
sockets when reloading, so instead we just try hard to pretend those proxies
are dead, while keeping the sockets opened.
A new global option, no-reused-socket", has been added, to restore the old
behavior of closing the sockets not bound to this process.
This reverts commit 266b1a8 ("MEDIUM: server: Inherit CLI weight changes and
agent-check weight responses") from Michal Idzikowski, which is still broken.
It stops propagating weights at the first error encountered, leaving servers
in a random state depending on what LB algorithms are used on other servers
tracking the one experiencing the weight change. It's unsure what the best
way to address this is, but we cannot leave the servers in an inconsistent
state between farms. For example :
backend site1
mode http
balance uri
hash-type consistent
server s1 127.0.0.1:8001 weight 10 track servers/s1
backend site2
mode http
balance uri
server s1 127.0.0.1:8001 weight 10 track servers/s1
backend site3
mode http
balance uri
hash-type consistent
server s1 127.0.0.1:8001 weight 10 track servers/s1
backend servers
server s1 127.0.0.1:8001 weight 10 check inter 1s
The weight change is applied on "servers/s1". It tries to propagate
to the servers tracking it, which are site1/s1, site2/s1 and site3/s1.
Let's say that "weight 50%" is requested. The servers are linked in
reverse-order, so the change is applied to "servers/s1", then to
"site3/s1", then to "site2/s1" and this one fails and rejects the
change. The change is aborted and never propagated to "site1/s1",
which keeps the server in a different state from "site3/s1". At the
very least, in case of error, the changes should probably be unrolled.
Also the error reported on the CLI (when changing from the CLI) simply says :
Backend is using a static LB algorithm and only accepts weights '0%' and '100%'.
Without more indications what the faulty backend is.
Let's revert this change for now, as initially feared it will definitely
cause more harm than good and at least needs to be revisited. It was never
backported to any stable branch so no backport is needed.
When agent-check or CLI command executes relative weight change this patch
propagates it to tracking server allowing grouping many backends running on
same server underneath. Additionaly in case with many src IPs many backends
can have shared state checker, so there won't be unnecessary health checks.

Another minor doc issue in the use-server example, use-server refers
to server "imap", but the server below is actually called "mail".
Renames the server from "mail" to "imap".
New boolean settings have been added to disable others. Most of them have "no-" as prefix.
"enabled" disables "disabled" setting,
"no-agent-check" disables "agent-check",
"no-backup" disables "backup",
"no-check" disables "check",
"no-check-ssl" disables "check-ssl",
"no-force-sslv3" disables "force-sslv3",
"no-force-tlsv10" disables "force-tlsv10",
"no-force-tlsv11" disables "force-tlsv11",
"no-force-tlsv12" disables "force-tlsv12,
"no-send-proxy" disables "send-proxy",
"no-send-proxy-v2" disables "send-proxy-v2",
"no-send-proxy-v2-ssl" disables "send-proxy-v2-ssl",
"no-send-proxy-v2-ssl-cn" disables "send-proxy-v2-ssl-cn",
"no-ssl" disables "ssl",
"no-verifyhost" disables "verifyhost",
"sslv3" disables "no-sslv3",
"ssl-reuse" disables "no-ssl-reuse",
"stick" disables "non-stick",
"tlsv10" disables "no-tlsv10",
"tlsv11" disables "no-tlsv11",
"tlsv12" disables "no-tlsv12",
"tls-tickets" disables "no-tls-tickets".
Settings with arguments are now supported on "default-server" lines:
"addr", "ca-file", "ciphers", "crl-file", "crt", "cookie", "namespace", "observe",
"redir", "sni", "source", "tcp-ut" and "track".
From now on, all server "settings" including the new ones above are supported by
"default-server" except "id" which is only supported on "server" lines.
When SIGUSR1 is received, haproxy enters in soft-stop and quits when no
connection remains.
It can happen that the instance remains alive for a long time, depending
on timeouts and traffic. This option ensures that soft-stop won't run
for too long.
Example:
global
hard-stop-after 30s # Once in soft-stop, the instance will remain
# alive for at most 30 seconds.
Guillaume Michaud reported against Cyril's haproxy-dconv project
that the index for the Examples section should be 2.5 instead of
2.4.
Should be backported to 1.7 and 1.6, so that the example section
can be linked to:
https://cbonte.github.io/haproxy-dconv/1.6/configuration.html#2.5
This adds a new "dynamic" keyword for the cookie option. If set, a cookie
will be generated for each server (assuming one isn't already provided on
the "server" line), from the IP of the server, the TCP port, and a secret
key provided. To provide the secret key, a new keyword as been added,
"dynamic-cookie-key", for backends.
Example :
backend bk_web
balance roundrobin
dynamic-cookie-key "bla"
cookie WEBSRV insert dynamic
server s1 127.0.0.1:80 check
server s2 192.168.56.1:80 check
This is a first step to be able to dynamically add and remove servers,
without modifying the configuration file, and still have all the load
balancers redirect the traffic to the right server.
Provide a way to generate session cookies, based on the IP address of the
server, the TCP port, and a secret key provided.
It adds "hostname" as a new sample fetch. It does exactly the same as
"%H" in a log format except that it can be used outside of log formats.

This is like the nbsrv() sample fetch function except that it works as
a converter so it can count the number of available servers of a backend

Use SSL_set_ex_data/SSL_get_ex_data standard API call to store capture.
We need to avoid internal structures/undocumented calls usage to try to
control the beast and limit painful compatibilities.
This new sample-fetches captures the cipher list offer by the client
SSL connection during the client-hello phase. This is useful for
fingerprint the SSL connection.
This patch used boringssl's callback to analyse CLientHello before any
handshake to extract key signature capabilities.
Certificat with better signature (ECDSA before RSA) is choosed
transparenty, if client can support it. RSA and ECDSA certificates can
be declare in a row (without order). This makes it possible to set
different ssl and filter parameter with crt-list.
crt-list is extend to support ssl configuration. You can now have
such line in crt-list <file>:
mycert.pem [npn h2,http/1.1]
Support include "npn", "alpn", "verify", "ca_file", "crl_file",
"ecdhe", "ciphers" configuration and ssl options.
"crt-base" is also supported to fetch certificates.
[wt: this one is in fact emulated using http-request deny. This
patch can thus be backported to 1.7, 1.6 and 1.5 so that users
of older versions do not add this keyword in their configs]
fc_rcvd_proxy : boolean
Returns true if the client initiated the connection with a PROXY protocol
header.
A flag is added on the struct connection if a PROXY header is successfully
parsed.
The older 'rsprep' directive allows modification of the status reason.
Extend 'http-response set-status' to take an optional string of the new
status reason.
http-response set-status 418 reason "I'm a coffeepot"
Matching updates in Lua code:

These 2 patches add ability to fetch frontend/backend name in your
logic, so they can be used later to make routing decisions (fe_name) or
taking some actions based on backend which responded to request (be_name).
In our case we needed a fetcher to be able to extract information we
needed from frontend name.
Definitions and examples for 51d.single and 51d.all have been added to
configuration.txt so it now appears in online documentation in addition
to the README, The 51degrees-property-name-list entry has also been
updated to make it clear that multiple properties can be added.

- DOC: update ROADMAP file
A new "option spop-check" statement has been added to enable server health
checks based on SPOP HELLO handshake. SPOP is the protocol used by SPOE filters
to talk to servers.
SPOE makes possible the communication with external components to retrieve some
info using an in-house binary protocol, the Stream Processing Offload Protocol
(SPOP). In the long term, its aim is to allow any kind of offloading on the
streams. This first version, besides being experimental, won't do lot of
things. The most important today is to validate the protocol design and lay the
foundations of what will, one day, be a full offload engine for the stream
processing.
So, for now, the SPOE can offload the stream processing before "tcp-request
content", "tcp-response content", "http-request" and "http-response" rules. And
it only supports variables creation/suppression. But, in spite of these limited
features, we can easily imagine to implement a SSO solution, an ip reputation
service or an ip geolocation service.
Internally, the SPOE is implemented as a filter. So, to use it, you must use
following line in a proxy proxy section:
frontend my-front
...
filter spoe [engine <name>] config <file>
...
It uses its own configuration file to keep the HAProxy configuration clean. It
is also a easy way to disable it by commenting out the filter line.
See "doc/SPOE.txt" for all details about the SPOE configuration.
It does the opposite of 'set-var' action/converter. It is really useful for
per-process variables. But, it can be used for any scope.
The lua function 'unset_var' has also been added.
Now it is possible to use variables attached to a process. The scope name is
'proc'. These variables are released only when HAProxy is stopped.
'tune.vars.proc-max-size' directive has been added to confiure the maximum
amount of memory used by "proc" variables. And because memory accounting is
hierachical for variables, memory for "proc" vars includes memory for "sess"
vars.
Now that it is possible to decide whether we prefer to use libc or the
state file to resolve the server's IP address and it is possible to change
a server's IP address at run time on the CLI, let's not restrict the reuse
of the address from the state file anymore to the DNS only.
The impact is that by default the state file will be considered first
(which matches its purpose) and only then the libc. This way any address
change performed at run time over the CLI will be preserved regardless
of DNS usage or not.
This adds new "hold" timers : nx, refused, timeout, other. This timers
will be used to tell HAProxy to keep an erroneous response as valid for
the corresponding period. For now they're only configured, not enforced.
Quite a lot of people have been complaining about option contstats not
working correctly anymore since about 1.4. The reason was that one reason
for the significant performance boost between 1.3 and 1.4 was the ability
to forward data between a server and a client without waking up the stream
manager. And we couldn't afford to force sessions to constantly wake it
up given that most of the people interested in contstats are also those
interested in high performance transmission.
An idea was experimented with in the past, consisting in limiting the
amount of transmissible data before waking it up, but it was not usable
on slow connections (eg: FTP over modem lines, RDP, SSH) as stats would
be updated too rarely if at all, so that idea was dropped.
During a discussion today another idea came up : ensure that stats are
updated once in a while, since it's the only thing that matters. It
happens that we have the request channel's analyse_exp timeout that is
used to wake the stream up after a configured delay, and that by
definition this timeout is not used when there's no more analyser
(otherwise the stream would wake up and the stats would be updated).
Thus here the idea is to reuse this timeout when there's no analyser
and set it to now+5 seconds so that a stream wakes up at least once
every 5 seconds to update its stats. It should be short enough to
provide smooth traffic graphs and to allow to debug outputs of "show
sess" more easily without inflicting too much load even for very large
number of concurrent connections.
This patch is simple enough and safe enough to be backportable to 1.6
if there is some demand.

When the tcp/http actions above were introduced in 1.7-dev4, we used to
proceed like this :
- set-src/set-dst would force the port to zero
- set-src-port/set-dst-port would not do anything if the address family is
neither AF_INET nor AF_INET6.
It was a stupid idea of mine to request this behaviour because it ensures
that these functions cannot be used in a wide number of situations. Because
of the first rule, it is necessary to save the source port one way or
another if only the address has to be changed (so you have to use an
variable). Due to the second rule, there's no way to set the source port
on a unix socket without first overwriting the address. And sometimes it's
really not convenient, especially when there's no way to guarantee that all
fields will properly be set.
In order to fix all this, this small change does the following :
- set-src/set-dst always preserve the original port even if the address
family changes. If the previous address family didn't have a port (eg:
AF_UNIX), then the port is set to zero ;
- set-src-port/set-dst-port always preserve the original address. If the
address doesn't have a port, then the family is forced to IPv4 and the
address to "0.0.0.0".
Thanks to this it now becomes possible to perform one action, the other or
both in any order.
The fe_req_rate is similar to fe_sess_rate, but fetches the number
of HTTP requests per second instead of connections/sessions per second.

Enable IP_BIND_ADDRESS_NO_PORT on backend connections when the source
address is specified without port or port ranges. This is supported
since Linux 4.2/libc 2.23.
If the kernel supports it but the libc doesn't, we can define it at
build time:
make [...] DEFINE=-DIP_BIND_ADDRESS_NO_PORT=24
For more informations about this feature, see Linux commit 90c337da
With Linux officially introducing SO_REUSEPORT support in 3.9 and
its mainstream adoption we have seen more people running into strange
SO_REUSEPORT related issues (a process management issue turning into
hard to diagnose problems because the kernel load-balances between the
new and an obsolete haproxy instance).
Also some people simply want the guarantee that the bind fails when
the old process is still bound.
This change makes SO_REUSEPORT configurable, introducing the command
line argument "-dR" and the noreuseport configuration directive.
A backport to 1.6 should be considered.
Tq is the time between the instant the connection is accepted and a
complete valid request is received. This time includes the handshake
(SSL / Proxy-Protocol), the idle when the browser does preconnect and
the request reception.
This patch decomposes %Tq in 3 measurements names %Th, %Ti, and %TR
which returns respectively the handshake time, the idle time and the
duration of valid request reception. It also adds %Ta which reports
the request's active time, which is the total time without %Th nor %Ti.
It replaces %Tt as the total time, reporting accurate measurements for
HTTP persistent connections.
%Th is avalaible for TCP and HTTP sessions, %Ti, %TR and %Ta are only
avalaible for HTTP connections.
In addition to this, we have new timestamps %tr, %trg and %trl, which
log the date of start of receipt of the request, respectively in the
default format, in GMT time and in local time (by analogy with %t, %T
and %Tl). All of them are obviously only available for HTTP. These values
are more relevant as they more accurately represent the request date
without being skewed by a browser's preconnect nor a keep-alive idle
time.
The HTTP log format and the CLF log format have been modified to
use %tr, %TR, and %Ta respectively instead of %t, %Tq and %Tt. This
way the default log formats now produce the expected output for users
who don't want to manually fiddle with the log-format directive.
Example with the following log-format :
log-format "%ci:%cp [%tr] %ft %b/%s h=%Th/i=%Ti/R=%TR/w=%Tw/c=%Tc/r=%Tr/a=%Ta/t=%Tt %ST %B %CC %CS %tsc %ac/%fc/%bc/%sc/%rc %sq/%bq %hr %hs %{+Q}r"
The request was sent by hand using "openssl s_client -connect" :
Aug 23 14:43:20 haproxy[25446]: 127.0.0.1:45636 [23/Aug/2016:14:43:20.221] test~ test/test h=6/i=2375/R=261/w=0/c=1/r=0/a=262/t=2643 200 145 - - ---- 1/1/0/0/0 0/0 "GET / HTTP/1.1"
=> 6 ms of SSL handshake, 2375 waiting before sending the first char (in
fact the time to type the first line), 261 ms before the end of the request,
no time spent in queue, 1 ms spend connecting to the server, immediate
response, total active time for this request = 262ms. Total time from accept
to close : 2643 ms.
The timing now decomposes like this :

Adding on to Thierry's work (http://git.haproxy.org/?p=haproxy.git;h=6310bef5)
I have added a few more fetchers for counters based on the tcp_info struct
maintained by the kernel :
fc_unacked, fc_sacked, fc_retrans, fc_fackets, fc_lost,
fc_reordering
Two fields were not added because they're version-dependant :
fc_rcv_rtt, fc_total_retrans
The fields name depend on the operating system. FreeBSD and NetBSD prefix
all the field names with "__" so we have to rely on a few #ifdef for
portability.
It is sometimes needed in application server environments to easily tell
if a source is local to the machine or a remote one, without necessarily
knowing all the local addresses (dhcp, vrrp, etc). Similarly in transparent
proxy configurations it is sometimes desired to tell the difference between
local and remote destination addresses.
This patch adds two new sample fetch functions for this :
dst_is_local : boolean
Returns true if the destination address of the incoming connection is local
to the system, or false if the address doesn't exist on the system, meaning
that it was intercepted in transparent mode. It can be useful to apply
certain rules by default to forwarded traffic and other rules to the traffic
targetting the real address of the machine. For example the stats page could
be delivered only on this address, or SSH access could be locally redirected.
Please note that the check involves a few system calls, so it's better to do
it only once per connection.
src_is_local : boolean
Returns true if the source address of the incoming connection is local to the
system, or false if the address doesn't exist on the system, meaning that it
comes from a remote machine. Note that UNIX addresses are considered local.
It can be useful to apply certain access restrictions based on where the
client comes from (eg: require auth or https for remote machines). Please
note that the check involves a few system calls, so it's better to do it only
once per connection.
This patch adds 4 new sample fetches which returns the RTT of the
established connexion and the RTT variance. The established connection
can be between the client and HAProxy, and between HAProxy and the
server. This is very useful for statistics. A great use case is the
estimation of the TCP connection time of the client. Note that the
RTT of the server side is not so interesting because we already have
the connect() time.
This enables tracking of sticky counters from current response. The only
difference from "http-request track-sc" is the <key> sample expression
can only make use of samples in response (eg. res.*, status etc.) and
samples below Layer 6.
The feature was introduced in 1.6-dev2 by commit 108b1dd ("MEDIUM:
http: configurable http result codes for http-request deny") but the
doc was missing. Thanks to Cyril for noticing.
This must be backported into 1.6.
This configures the client-facing connection to receive a NetScaler
Client IP insertion protocol header before any byte is read from the
socket. This is equivalent to having the "accept-netscaler-cip" keyword
on the "bind" line, except that using the TCP rule allows the PROXY
protocol to be accepted only for certain IP address ranges using an ACL.
This is convenient when multiple layers of load balancers are passed
through by traffic coming from public hosts.
When NetScaler application switch is used as L3+ switch, informations
regarding the original IP and TCP headers are lost as a new TCP
connection is created between the NetScaler and the backend server.
NetScaler provides a feature to insert in the TCP data the original data
that can then be consumed by the backend server.
Specifications and documentations from NetScaler:
https://support.citrix.com/article/CTX205670https://www.citrix.com/blogs/2016/04/25/how-to-enable-client-ip-in-tcpip-option-of-netscaler/
When CIP is enabled on the NetScaler, then a TCP packet is inserted just after
the TCP handshake. This is composed as:
- CIP magic number : 4 bytes
Both sender and receiver have to agree on a magic number so that
they both handle the incoming data as a NetScaler Client IP insertion
packet.
- Header length : 4 bytes
Defines the length on the remaining data.
- IP header : >= 20 bytes if IPv4, 40 bytes if IPv6
Contains the header of the last IP packet sent by the client during TCP
handshake.
- TCP header : >= 20 bytes
Contains the header of the last TCP packet sent by the client during TCP
handshake.
SNI filters used to be ignored with multicerts (eg: those providing
ECDSA and RSA at the same time). This patch makes them work like
other certs.
Note: most of the changes in this patch are due to an extra level of
indent, read it with "git show -b".
The 'set-src' action was not available for tcp actions The action code
has been converted into a function in proto_tcp.c to be used for both
'http-request' and 'tcp-request connection' actions.
Both http and tcp keywords are registered in proto_tcp.c
As suggested by Pavlos, it's too bad that we didn't have a %Td log
format tag given that there are a few mentions of Td corresponding
to the data transmission time already in the doc, so this is now done.
Just like the other specifiers, we report -1 if the connection failed
before reaching the data transmission state.

This is very useful in complex architecture systems where HAproxy
is balancing DB connections for example. We want to keep the maxconn
high in order to avoid issues with queueing on the LB level when
there is slowness on another part of the system. Example is a case of
an architecture where each thread opens multiple DB connections, which
if get stuck in queue cause a snowball effect (old connections aren't
closed, new ones cannot be established). These connections are mostly
idle and the DB server has no problem handling thousands of them.
Allowing us to dynamically set maxconn depending on the backend usage
(LA, CPU, memory, etc.) enables us to have high maxconn for situations
like above, but lowering it in case there are real issues where the
backend servers become overloaded (cache issues, DB gets hit hard).
The configuration documention has been updated. Doc about the filter line has
been added and a new chapter (§. 9) has been created to list and document
supported filters (for now, flt_trace and flt_http_comp).
The developer documentation about filters has also been added. The is a "pre"
version. Incoming changes in the filter API will require an update.
This documentation requires a deeper review and some TODO need to be complete.
Adds some examples regarding shorthand IPv4 address notation which might
be confused with RFC 4632 CIDR notation, leading to different than
expected results.
Commit c8f0e78 ("DOC: typo: req.uri is now replaced by capture.req.uri")
fixed a discrepancy in the doc but the scheme is still missing, resulting
in a redirect loop. Let's fix this as well. This should be backported to
1.5.
It worth mentionning "timeout http-request" in the "timeout client"
documentation paragraph, to ensure nobody misses this important setting.
backport: 1.5 and above
Adds a little more clarity to the description of the maximum sizes of
the different variable scopes and adds a note about what happens when
the space allocated for variables is too small.
Also fixes some typos and grammar/spelling issues re/ variables and
their naming conventions, copied throughout the document.
Regarding the minor update introduced in the
cd6c3c7cb4 commit, the DeviceAtlas
module is now able to use up to 12 device properties via the
new ARG12 macro.

This options prioritize th choice of an ip address matching a network. This is
useful with clouds to prefer a local ip. In some cases, a cloud high
avalailibility service can be announced with many ip addresses on many
differents datacenters. The latency between datacenter is not negligible, so
this patch permitsto prefers a local datacenter. If none address matchs the
configured network, another address is selected.
With new init systems such as systemd, environment variables became a
real mess because they're only considered on startup but not on reload
since the init script's variables cannot be passed to the process that
is signaled to reload.
This commit introduces an alternative method consisting in making it
possible to modify the environment from the global section with directives
like "setenv", "unsetenv", "presetenv" and "resetenv".
Since haproxy supports loading multiple config files, it now becomes
possible to put the host-dependant variables in one file and to
distribute the rest of the configuration to all nodes, without having
to deal with the init system's deficiencies.
Environment changes take effect immediately when the directives are
processed, so it's possible to do perform the same operations as are
usually performed in regular service config files.
The +E mode escapes characters '"', '\' and ']' with '\' as prefix. It
mostly makes sense to use it in the RFC5424 structured-data log formats.
Example:
log-format-sd %{+Q,+E}o\ [exampleSDID@1234\ header=%[capture.req.hdr(0)]]
Michał Pasierb reported doc inconsistencies regarding the old default
HTTP tunnel mode.
This patch fixes a few of those inconsistencies and should be backported
to both 1.6 and 1.5.

This setting used to be assigned to a variable tunable from a constant
and for an unknown reason never made its way into the config parser.
tune.recv_enough <number>
Haproxy uses some hints to detect that a short read indicates the end of the
socket buffers. One of them is that a read returns more than <recv_enough>
bytes, which defaults to 10136 (7 segments of 1448 each). This default value
may be changed by this setting to better deal with workloads involving lots
of short messages such as telnet or SSH sessions.
add referrence for "http-request" or "http-response" in reqXXX/rspXXX
directives.
add a paragraph in "http-request" and "http-response" stating that
reqXXX/rspXXX directives are discouraged
The documentation missed the explanation and relation between the
timeout http-request and option http-buffer-request.
Combined together, it helps protecting against slow POST types of
attacks.
[wt: backport to 1.6]
It is possible to create a http capture rule which points to a capture slot
id which does not exist.
Current patch prevent this when parsing configuration and prevent running
configuration which contains such rules.
This configuration is now invalid:
frontend f
bind :8080
http-request capture req.hdr(User-Agent) id 0
default_backend b
this one as well:
frontend f
bind :8080
declare capture request len 32 # implicit id is 0 here
http-request capture req.hdr(User-Agent) id 1
default_backend b
It applies of course to both http-request and http-response rules.
Causes HAProxy to emit a static string to the agent on every check,
so that you can independently control multiple services running
behind a single agent port.
It was reported that an example was manipulating a "Referrer" header instead
of the known "Referer" one. Even if it's an example wich doesn't break things,
the typo can be fixed.
The fix should be backported in 1.4/1.5/1.6 branches.
Commit 44aed90ce1 moved the stats socket
documentation from config to management but the remaining references to
section 9.2 were not updated; improve it to be less confusing.

This is equivalent to commit 2af207a ("MEDIUM: tcp: implement tcp-ut
bind option to set TCP_USER_TIMEOUT") except that this time it works
on the server side. The purpose is to detect dead server connections
even when checks are rare, disabled, or after a soft reload (since
checks are disabled there as well), and to ensure client connections
will get killed faster.

This commit adds support for dumping all resolver stats. Specifically
if a command 'show stats resolvers' is issued withOUT a resolver section
id, we dump all known resolver sections. If none are configured, a
message is displayed indicating that.
req.ssl_st_ext : integer
Returns 0 if the client didn't send a SessionTicket TLS Extension (RFC5077)
Returns 1 if the client sent SessionTicket TLS Extension
Returns 2 if the client also sent non-zero length TLS SessionTicket
Chapter "Mailers" was missing from the summary, tabulations were used and
several lines exceeded 80 columns : some lines still exceeds the 80 columns
limit but are left as is, as it mostly concerns syntax and configuration
examples.

This stops the evaluation of the rules and makes the client-facing
connection suddenly disappear using a system-dependant way that tries
to prevent the client from being notified. The effect it then that the
client still sees an established connection while there's none on
HAProxy. The purpose is to achieve a comparable effect to "tarpit"
except that it doesn't use any local resource at all on the machine
running HAProxy. It can resist much higher loads than "tarpit", and
slow down stronger attackers. It is important to undestand the impact
of using this mechanism. All stateful equipments placed between the
client and HAProxy (firewalls, proxies, load balancers) will also keep
the established connection for a long time and may suffer from this
action. On modern Linux systems running with enough privileges, the
TCP_REPAIR socket option is used to block the emission of a TCP
reset. On other systems, the socket's TTL is reduced to 1 so that the
TCP reset doesn't pass the first router, though it's still delivered to
local networks.
Documentation related to a new global directive.
Purpose of this directive is to store a file path into the global
structure of HAProxy. The file pointed by the path may be used by
HAProxy to retrieve server state from the previous running process
after a reload occured.
