d06f31c443 DOC: Add note about encrypted password CPU usage
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
it mentioned in the relevant documentation section might spare someone
some confusion in the future.

60ca10a372 MINOR: connection: report the major HTTP version from the MUX for logging (fc_http_major)
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.

6251902e67 MINOR: threads: Add thread-map config parameter in the global section
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.

71a6a8efaa MEDIUM: threads/filters: Add init/deinit callback per thread
Now, it is possible to define init_per_thread and deinit_per_thread callbacks to
deal with ressources allocation for each thread.

This is the filter responsibility to deal with concurrency. This is also the
filter responsibility to know if HAProxy is started with some threads. A good
way to do so is to check "global.nbthread" value. If it is greater than 1, then
_per_thread callbacks will be called.

67957bd59e MAJOR: dns: Refactor the DNS code
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.

344c4ab6a9 MEDIUM: spoe/rules: Process "send-spoe-group" action
The messages processing is done using existing functions. So here, the main task
is to find the SPOE engine to use. To do so, we loop on all filter instances
attached to the stream. For each, we check if it is a SPOE filter and, if yes,
if its name is the one used to declare the "send-spoe-group" action.

We also take care to return an error if the action processing is interrupted by
HAProxy (because of a timeout or an error at the HAProxy level). This is done by
checking if the flag ACT_FLAG_FINAL is set.

The function spoe_send_group is the action_ptr callback ot

76c09ef8de MEDIUM: spoe/rules: Add "send-spoe-group" action for tcp/http rules
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.

11610f3b5a MEDIUM: spoe: Parse new "spoe-group" section in SPOE config file
For now, this section is only parsed. It should have the following format:

    spoe-group <grp-name>
      messages <msg-name> ...

And then SPOE groups must be referenced in spoe-agent section:

    spoe-agnt <name>
        ...
	groups <grp-name> ...

The purpose of these groups is to trigger messages sending from TCP or HTTP
rules, directly from HAProxy configuration, and not on specific event. This part
will be added in another patch.

It is important to note that a message belongs at most to a group.

7ee8667c99 MINOR: spoe: Check uniqness of SPOE engine names during config parsing
The engine name is now kept in "spoe_config" struture. Because a SPOE filter can
be declared without engine name, we use the SPOE agent name by default. Then,
its uniqness is checked against all others SPOE engines configured for the same
proxy.

57583e474e MEDIUM: spoe: Add support of ACLS to enable or disable sending of SPOE messages
Now, it is possible to conditionnaly send a SPOE message by adding an ACL-based
condition on the "event" line, in a "spoe-message" section. Here is the example
coming for the SPOE documentation:

    spoe-message get-ip-reputation
        args ip=src
        event on-client-session if ! { src -f /etc/haproxy/whitelist.lst }

To avoid mixin with proxy's ACLs, each SPOE message has its private ACL list. It
possible to declare named ACLs in "spoe-message" section, using the same syntax
than for proxies. So we can rewrite the previous example to use a named ACL:

    spoe-message get-ip-reputation
        args ip=src
	acl ip-whitelisted src -f /etc/haproxy/whitelist.lst
        event on-client-session if ! ip-whitelisted

ACL-based conditions are executed in the context of the stream that handle the
client and the server connections.

9679ac997a MINOR: ssl: Don't abuse ssl_options.
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.

ccaa7de72e MINOR: ssl/proto_http: Add keywords to take care of early data.
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.

c2aae74f01 MEDIUM: ssl: Handle early data with OpenSSL 1.1.1
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 :

Openssl >= 1.1.1.

to 0-RTT processing :

d716f9bacf MINOR: payload: add new sample fetch functions to process distcc protocol
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

ff2b7afe0b MINOR: server: add the srv_queue() sample fetch method
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.

ddcde195eb MINOR: ssl: rework smp_fetch_ssl_fc_cl_str without internal ssl use
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.

b6c8b0db04 DOC: Add note about "* " prefix in CSV stats
The check_status field in the CSV stats output is conditionally prefixed
with "* " if a check is currently underway. This can trip tools that
parse the CSV output and compare against a well known list of values.

This commit just adds this bit to the documentation.

87e4302707 DOC: Refer to Mozilla TLS info / config generator
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.

9d8dbbc56b MINOR: dns: Maximum DNS udp payload set to 8192
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.

686408bb6c MINOR: dns: default "hold obsolete" timeout set to 0
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.

2af08fe3de MINOR: dns: enabled edns0 extension and make accpeted payload size tunable
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.

a8c6db8d2d MINOR: dns: Cache previous DNS answers.
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.

7a4a0ac71d MINOR: cli: add a new "show fd" command
This one dumps the fdtab for all active FDs with some quickly interpretable
characters to read the flags (like upper case=set, lower case=unset). It
can probably be improved to report fdupdt[] and/or fdinfo[] but at least it
provides a good start and allows to see how FDs are seen. When the fd owner
is a connection, its flags are also reported as it can help compare with the
polling status, and the target (fe/px/sv) as well. When it's a listener, the
listener's state is reported as well as the frontend it belongs to.

ad92a9a7be BUG/MINOR: ssl: make use of the name in SNI before verifyhost
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.
