in the context of seamless reload and busy polling, older processes will
create unecessary cpu conflicts; we can assume there is no need for busy
polling for old processes which are waiting to be terminated.
This patch is not a bug fix itself but might be a good stability
improvment when you are un the context of frequent seamless reloads with
a high "hard-stop-after" value; for that reasons I think this patch
should be backported in all 2.x versions.

This action is very similar to "replace-uri" except that it only acts on the
path component. This is assumed to better match users' expectations when they
used to rely on "replace-uri" in HTTP/1 because mostly origin forms were used
in H1 while mostly absolute URI form is used in H2, and their rules very often
start with a '/', and as such do not match.
It could help users to get this backported to 2.0 and 2.1.
As discussed in the thread below [1], the debug converter is currently
not of much use given that it's only built when DEBUG_EXPR is set, and
it is limited to stderr only.
This patch changes this to make it take an optional prefix and an optional
target sink so that it can log to stdout, stderr or a ring buffer. The
default output is the "buf0" ring buffer, that can be consulted from the
CLI.
[1] https://www.mail-archive.com/haproxy@formilux.org/msg35671.html
Note: if this patch is backported, it also requires the following commit to
work: 46dfd78cbf ("BUG/MINOR: sample: always check converters' arguments").
With H2 deployments becoming more common, replace-uri starts to hit
users by not always matching absolute URIs due to rules expecting the
URI to start with a '/'.
As mentionned in bug #405 we continue to reference architecture.txt from
places in the doc despite this file not being packaged for many years.
Better drop the reference if it's confusing.
HAProxy doesn't need to call executables at run time (except when using
external checks which are strongly recommended against), and is even expected
to isolate itself into an empty chroot. As such, there basically is no valid
reason to allow a setuid executable to be called without the user being fully
aware of the risks. In a situation where haproxy would need to call external
checks and/or disable chroot, exploiting a vulnerability in a library or in
haproxy itself could lead to the execution of an external program. On Linux
it is possible to lock the process so that any setuid bit present on such an
executable is ignored. This significantly reduces the risk of privilege
escalation in such a situation. This is what haproxy does by default. In case
this causes a problem to an external check (for example one which would need
the "ping" command), then it is possible to disable this protection by
explicitly adding this directive in the global section. If enabled, it is
possible to turn it back off by prefixing it with the "no" keyword.
Before the option:
$ socat - /tmp/sock1 <<< "expert-mode on; debug dev exec sudo /bin/id"
uid=0(root) gid=0(root) groups=0(root
After the option:
$ socat - /tmp/sock1 <<< "expert-mode on; debug dev exec sudo /bin/id"
sudo: effective uid is not 0, is /usr/bin/sudo on a file system with the
'nosuid' option set or an NFS file system without root privileges?
Some concerns are regularly raised about the risk to inherit some Lua
files which make use of a fork (e.g. via os.execute()) as well as
whether or not some of bugs we fix might or not be exploitable to run
some code. Given that haproxy is event-driven, any foreground activity
completely stops processing and is easy to detect, but background
activity is a different story. A Lua script could very well discretely
fork a sub-process connecting to a remote location and taking commands,
and some injected code could also try to hide its activity by creating
a process or a thread without blocking the rest of the processing. While
such activities should be extremely limited when run in an empty chroot
without any permission, it would be better to get a higher assurance
they cannot happen.
This patch introduces something very simple: it limits the number of
processes and threads to zero in the workers after the last thread was
created. By doing so, it effectively instructs the system to fail on
any fork() or clone() syscall. Thus any undesired activity has to happen
in the foreground and is way easier to detect.
This will obviously break external checks (whose concept is already
totally insecure), and for this reason a new option
"insecure-fork-wanted" was added to disable this protection, and it
is suggested in the fork() error report from the checks. It is
obviously recommended not to use it and to reconsider the reasons
leading to it being enabled in the first place.
If for any reason we fail to disable forks, we still start because it
could be imaginable that some operating systems refuse to set this
limit to zero, but in this case we emit a warning, that may or may not
be reported since we're after the fork point. Ideally over the long
term it should be conditionned by strict-limits and cause a hard fail.
Add clarification and example to string matching on binary samples,
as comparison stops at first null byte due to strncmp behaviour.
Backporting all the way down to 1.5 is suggested as it might save
from headaches.

The use-service action may be used in tcp-request and http-request rules. It was
added to customize HAproxy reply to a client using an applet (initially a lua
applet). But the documentation was missing.
This patch may be backported as far as 1.6.
It was noted in #48 that there are times when a configuration
may use the server-template directive with SRV records and
simultaneously want to control weights using an agent-check or
through the runtime api. This patch adds a new option
"ignore-weight" to the "resolve-opts" directive.
When specified, any weight indicated within an SRV record will
be ignored. This is for both initial resolution and ongoing
resolution.
INITCALLs are used a lot in the code now and were not documented, resulting
in each user having to grep for functions in other files. This doc is not
perfect but aims at improving the situation. It documents what's been
available since 1.9 and may be backported there if it helps though it's
unlikely to be needed as it's mostly aimed at developers.
The limitation on the first chunk for chunked requests was true for the legacy
HTTP mode. But, it does not exist with the HTX. Becaue, the legacy HTTP mode was
removed in 2.1, this limitation does not exist anymore.

Allow the sc-set-gpt0 action to set GPT0 to a value dynamically evaluated from
its <expr> argument (in addition to the existing static <int> alternative).
This patch is easy to review: let's call parse_logsrv() function to parse
"log" directive as this is already for other sections for proxies.
This enable us to log incoming TCP connections for the listeners for "peers"
sections.
Update the documentation for "peers" section.
These keywords received a second argument with commit ae6f125 ("MINOR:
sample: add us/ms support to date/http_date"). Each argument is optional,
it's not either both or none.

Issue#342
It can be sometimes interesting to have a timestamp with a
resolution of less than a second.
It is currently painful to obtain this, because concatenation
of date and date_us lead to a shorter timestamp during first
100ms of a second, which is not parseable and needs ugly ACLs
in configuration to prepend 0s when needed.
To improve this, add an optional <unit> parameter to date sample
to report an integer with desired unit.
Also support this unit in http_date converter to report
a date string with sub-second precision.
this patch introduces a strict-limits parameter which enforces the
setrlimit setting instead of a warning. This option can be forcingly
disable with the "no" keyword.
The general aim of this patch is to avoid bad surprises on a production
environment where you change the maxconn for example, a new fd limit is
calculated, but cannot be set because of sysfs setting. In that case you
might want to have an explicit failure to be aware of it before seeing
your traffic going down. During a global rollout it is also useful to
explictly fail as most progressive rollout would simply check the
general health check of the process.
As discussed, plan to use the strict by default mode starting from v2.3.

in global config parsing, we currently expect to have a possible no
keyword (KWN_NO), but we never allow it in config parsing.

possible KWN_NO.

Cyril Bont reported that the doc contains two chapters number 6,
one of which is a leftover of the section about old header manipulation
directives that were removed by commit a6a56e6 ("MEDIUM: config: Remove

remains conditionned to DEBUG_DEV because it can have a security implication
on the system. The commands are not listed unless "expert-mode on" was first
entered on the CLI :

debug dev close <fd> : close this file descriptor
debug dev delay [ms] : sleep this long
debug dev exec [cmd] ... : show this command's output
debug dev exit [code] : immediately exit the process

debug dev log [msg] ... : send this msg to global logs
debug dev loop [ms] : loop this long
debug dev panic : immediately trigger a panic
debug dev stream ... : show/manipulate stream flags

Usage: debug dev stream { <obj> <op> <value> | wake }*
<obj> = {strm | strm.f | sif.f | sif.s | sif.x | sib.f | sib.s | sib.x |
txn.f | req.f | req.r | req.w | res.f | res.r | res.w}
<op> = {'' (show) | '=' (assign) | '^' (xor) | '+' (or) | '-' (andnot)}
<value> = 'now' | 64-bit dec/hex integer (0x prefix supported)
'wake' wakes the stream asssigned to 'strm' (default: current)
Some commands like the debug ones are not enabled by default but can be
useful on some production environments. In order to avoid the temptation
of using them incorrectly, let's introduce an "expert" mode for a CLI
connection, which allows some commands to appear and be used. It is
enabled by command "expert-mode on" which is not listed by default.
As reported in issue #335, a lot of contention happens on the PATLRU lock
when performing expensive regex lookups. This is absurd since the purpose
of the LRU cache was to have a fast cache for expressions, thus the cache
must not be shared between threads and must remain lockless.
This commit makes the LRU cache thread-local and gets rid of the PATLRU
lock. A test with 7 threads on 4 cores climbed from 67kH/s to 369kH/s,
or a scalability factor of 5.5.
Given the huge performance difference and the regression caused to
users migrating from processes to threads, this should be backported at
least to 2.0.
Thanks to Brian Diekelman for his detailed report about this regression.
There are 2 kinds of tcp info fetchers. Those returning a time value (fc_rtt and
fc_rttval) and those returning a counter (fc_unacked, fc_sacked, fc_retrans,
fc_fackets, fc_lost, fc_reordering). Because of a bug, the counters were handled
as time values, and by default, were divided by 1000 (because of an invalid
conversion from us to ms). To work around this bug and have the right value, the
argument "us" had to be specified.
So now, tcp info fetchers returning a counter don't support any argument
anymore. To not break old configurations, if an argument is provided, it is
ignored and a warning is emitted during the configuration parsing.
In addition, parameter validiation is now performed during the configuration
parsing.
This patch must be backported as far as 1.7.
Now "show info" supports "desc" after the default and "typed" formats,
and "show stat" supports this after the typed format. In both cases
this appends the description for the represented metric between double
quotes. The same could be done for JSON output but would possibly require
to update the schema first.
The directive causes existing an header to be removed, which is not
explicitly mentioned though already being relied on, and also mention
the fast that it should not be used to modify transport level headers
and that doing it on Host is more than border-line and definitely not
a supported long-term option eventhough it currently works.

In the management guide, this command was still referenced as "show stat
resolvers" instead of "show resolvers". The cli command was fixed by the commit
ff88efbd7 ("BUG/MINOR: dns: Fix CLI keyword declaration").
This patch fixes the issue #296. It can be backported as fas as 1.7.
Now, following sample fetches may be used to get information about
authentication:
* http_auth_type : returns the auth method as supplied in Authorization header
* http_auth_user : returns the auth user as supplied in Authorization header
* http_auth_pass : returns the auth pass as supplied in Authorization header
Only Basic authentication is supported.
