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.
Currently we unconditionally set SSL_OP_CIPHER_SERVER_PREFERENCE [1],
which may not always be a good thing.
The benefit of server side cipher prioritization may not apply to all
cases out there, and it appears that the various SSL libs are going away
from this recommendation ([2], [3]), as insecure ciphers suites are
properly blacklisted/removed and honoring the client's preference is
more likely to improve user experience (for example using SW-friendly
ciphers on devices without HW AES support).
This is especially true for TLSv1.3, which will restrict the cipher
suites to just AES-GCM and Chacha20/Poly1305.
Apache [4], nginx [5] and others give admins full flexibility, we should
as well.
The initial proposal to change the current default and add a
"prefer-server-ciphers" option (as implemented in e566ecb) has been
declined due to the possible security impact.
This patch implements prefer-client-ciphers without changing the defaults.

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
name retrieved using a sample fetch or an environment variable.

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:
- AppletHTTP.set_status

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.
