## General note on this document
This document is "descriptive/post-factual" in that it documents pratices that
are in use; it is not "definitive/pre-factual" in prescribing practices.
This means that when a procedure changes, it is agreed upon, then put into
practice, and then documented here. If this document doesn't match reality,
it's the document that needs to be updated, not reality.

New contributions are done against the head of the master branch. The CI
systems will pick up the Github Pull Requests or the new patch from
Patchwork, run some basic build and functional tests and will merge them
into the branch automatically on success.
Code on the develop branch will then be further tested and reviewed by the
community and merged to master on a regular interval.
Patchwork, run some basic build and functional tests.
For each major release (1.0, 1.1 etc) a new release branch is created based
on the master.
There was an attempt to use a "develop" branch automatically maintained by
the CI system. This is not currently in active use, though the system is
operational. If the "develop" branch is in active use and this paragraph
is still here, this document obviously wasn't updated.

### Code styling / format
GNU coding standards apply. Indentation follows the result of invoking GNU
indent (as of 2.2.8a) with the `-nut -nfc1` arguments.
Coding style standards in FRR vary depending on location. Pre-existing
code uses GNU coding standards. New code may use Linux kernel coding style.
GNU coding style apply to the following parts:
* lib/
* zebra/
* bgpd/
* ospfd/
* ospf6d/
* isisd/
* ripd/
* ripngd/
* vtysh/
Linux kernel coding style applies to:
* nhrpd/
* watchfrr/
* pimd/
* lib/{checksum,hook,imsg-buffer,imsg,libfrr,md5,module,monotime,queue}.[ch]
BSD coding style applies to:
* ldpd/
**Whitespace changes in untouched parts of the code are not acceptable in
patches that change actual code.** To change/fix formatting issues, please
create a separate patch that only does formatting changes and nothing else.
It is acceptable to rewrap entire files to Linux kernel style, but this
**MUST** come as a separate patch that does nothing other than this
reformatting.
#### GNU style
For GNU coding style, Indentation follows the result of invoking GNU indent:
```
indent -nut -nfc1 file_for_submission.c
```
Please don’t reformat existing files (or only sections modified by your
changes), even if they don’t follow the standard. This makes it very hard to
highlight the changes
Originally, tabs were used instead of spaces, with tabs are every 8 columns.
However, tab interoperability issues mean space characters are now preferred for
new changes. We generally only clean up whitespace when code is unmaintainable
due to whitespace issues, to minimise merging conflicts.
#### Linux kernel & BSD style
These styles are documented externally:
* [https://www.kernel.org/doc/Documentation/CodingStyle](https://www.kernel.org/doc/Documentation/CodingStyle).
* [http://man.openbsd.org/style](http://man.openbsd.org/style)
They are relatively similar but differ in details.
pimd deviates from Linux kernel style in using 2 spaces for indentation, with
Tabs replacing 8 spaces, as well as adding a line break between `}` and `else`.
It is acceptable to convert indentation in pimd/ to Linux kernel style, but
please convert an entire file at a time. (Rationale: apart from 2-space
indentation, the styles are sufficiently close to not upset when mixed.)
Unlike GNU style, these styles use tabs, not spaces.

@section Loadable Module Support
FRR supports loading extension modules at startup. Loading, reloading or
unloading modules at runtime is not supported (yet). To load a module, use
the following command line option at daemon startup:
@table @samp
@item -M @var{module:options}
@itemx --module @var{module:options}
Load the specified module, optionally passing options to it. If the module
name contains a slash (/), it is assumed to be a full pathname to a file to
be loaded. If it does not contain a slash, the
@code{@value{INSTALL_PREFIX_MODULES}} directory is searched for a module of
the given name; first with the daemon name prepended (e.g. @code{zebra_mod}
for @code{mod}), then without the daemon name prepended.
This option is available on all daemons, though some daemons may not have
any modules available to be loaded.
@end table
@subsection The SNMP Module
If SNMP is enabled during compile-time and installed as part of the package,
the @code{snmp} module can be loaded for the @command{zebra},
@command{bgpd}, @command{ospfd}, @command{ospf6d} and @command{ripd} daemons.
The module ignores any options passed to it. Refer to @ref{SNMP Support}
for information on its usage.
@subsection The FPM Module
If FPM is enabled during compile-time and installed as part of the package,
the @code{fpm} module can be loaded for the @command{zebra} daemon. This
provides the Forwarding Plane Manager ("FPM") API.
The module expects its argument to be either @code{netlink} or
@code{protobuf}, specifying the encapsulation to use. @code{netlink} is the
default, and @code{protobuf} may not be available if the module was built
without protobuf support. Refer to @ref{zebra FIB push interface} for more
information.

It uses `dlopen()` to load DSOs at startup.
## Limitations
* can't load, unload, or reload during runtime. This just needs some work
and can probably be done in the future.
* doesn't fix any of the "things need to be changed in the code in the library"
issues. Most prominently, you can't add a CLI node because CLI nodes are
listed in the library...
* if your module crashes, the daemon crashes. Should be obvious.
* **does not provide a stable API or ABI**. Your module must match a version
of FRR and you may have to update it frequently to match changes.
* **does not create a license boundary**. Your module will need to link
libzebra and include header files from the daemons, meaning it will be
GPL-encumbered.
## Installation
Look for `moduledir` in `configure.ac`, default is normally
`/usr/lib64/frr/modules` but depends on `--libdir` / `--prefix`.
The daemon's name is prepended when looking for a module, e.g. "snmp" tries
to find "zebra_snmp" first when used in zebra. This is just to make it nicer
for the user, with the snmp module having the same name everywhere.
Modules can be packaged separately from FRR. The SNMP and FPM modules are
good candidates for this because they have dependencies (net-snmp / protobuf)
that are not FRR dependencies. However, any distro packages should have an
"exact-match" dependency onto the FRR package. Using a module from a
different FRR version will probably blow up nicely.
For snapcraft (and during development), modules can be loaded with full path
(e.g. -M `$SNAP/lib/frr/modules/zebra_snmp.so`). Note that libtool puts output
files in the .libs directory, so during development you have to use
`./zebra -M .libs/zebra_snmp.so`.
## Creating a module
... best to look at the existing SNMP or FPM modules.
Basic boilerplate:
```
#include "hook.h"
#include "module.h"
static int
module_init (void)
{
hook_register(frr_late_init, module_late_init);
return 0;
}
FRR_MODULE_SETUP(
.name = "my module",
.version = "0.0",
.description = "my module",
.init = module_init,
)
```
The `frr_late_init` hook will be called after the daemon has finished its
other startup and is about to enter the main event loop; this is the best
place for most initialisation.
## Compiler & Linker magic
There's a `THIS_MODULE` (like in the Linux kernel), which uses `visibility`
attributes to restrict it to the current module. If you get a linker error
with `_frrmod_this_module`, there is some linker SNAFU. This shouldn't be
possible, though one way to get it would be to not include libzebra (which
provides a fallback definition for the symbol).
libzebra and the daemons each have their own `THIS_MODULE`, as do all loadable
modules. In any other libraries (e.g. `libfrrsnmp`), `THIS_MODULE` will use
the definition in libzebra; same applies if the main executable doesn't use
`FRR_DAEMON_INFO` (e.g. all testcases).
The deciding factor here is "what dynamic linker unit are you using the symbol
from." If you're in a library function and want to know who called you, you
can't use `THIS_MODULE` (because that'll just tell you you're in the library).
Put a macro around your function that adds `THIS_MODULE` in the *caller's
code calling your function*.
The idea is to use this in the future for module unloading. Hooks already
remember which module they were installed by, as groundwork for a function
that removes all of a module's installed hooks.
There's also the `frr_module` symbol in modules, pretty much a standard entry
point for loadable modules.
## Hooks
Hooks are just points in the code where you can register your callback to
be called. The parameter list is specific to the hook point. Since there is
no stable API, the hook code has some extra type safety checks making sure
you get a compiler warning when the hook parameter list doesn't match your
callback. Don't ignore these warnings.
## Relation to MTYPE macros
The MTYPE macros, while primarily designed to decouple MTYPEs from the library
and beautify the code, also work very nicely with loadable modules -- both
constructors and destructors are executed when loading/unloading modules.
This means there is absolutely no change required to MTYPEs, you can just use
them in a module and they will even clean up themselves when we implement
module unloading and an unload happens. In fact, it's impossible to create
a bug where unloading fails to de-register a MTYPE.

#
# SYNOPSIS
#
# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
#
# DESCRIPTION
#
# This macro figures out how to build C programs using POSIX threads. It
# sets the PTHREAD_LIBS output variable to the threads library and linker
# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
# flags that are needed. (The user can also force certain compiler
# flags/libs to be tested by setting these environment variables.)
#
# Also sets PTHREAD_CC to any special C compiler that is needed for
# multi-threaded programs (defaults to the value of CC otherwise). (This
# is necessary on AIX to use the special cc_r compiler alias.)
#
# NOTE: You are assumed to not only compile your program with these flags,
# but also link it with them as well. e.g. you should link with
# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
#
# If you are only building threads programs, you may wish to use these
# variables in your default LIBS, CFLAGS, and CC:
#
# LIBS="$PTHREAD_LIBS $LIBS"
# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
# CC="$PTHREAD_CC"
#
# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
# (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
#
# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
# PTHREAD_PRIO_INHERIT symbol is defined when compiling with
# PTHREAD_CFLAGS.
#
# ACTION-IF-FOUND is a list of shell commands to run if a threads library
# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
# is not found. If ACTION-IF-FOUND is not specified, the default action
# will define HAVE_PTHREAD.
#
# Please let the authors know if this macro fails on any platform, or if
# you have any other suggestions or comments. This macro was based on work
# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help

# -mthreads: Mingw32/gcc, Lynx/gcc
# -mt: Sun Workshop C (may only link SunOS threads [-lthread], but it
