Sphinx actually does work with a parallel build, if the doctree creation
is a separate step (which the other builds will then just read
unmodified.) This can be done with the "dummy" target.
This also adds "-j6" to sphinx-build and adds a "--disable-doc-html"
switch on ./configure to turn on/off building HTML docs separately.
Also, HTML docs are now installed by "make install" to
/usr/share/doc/frr/html.

The smux.c code has not been able to compile for 2+ years
and no-one has noticed. Additionally net-snmp has marked

Since no-one has noticed and it's been broken and smux integration

Currently, make check runs the unit tests and reports pass/fail,
but we have no way to guage how much of the code is covered by
these tests. gcov provides those statistics on a per source
file basis, but requires special CFLAGS and LDFLAGS. Here, we
add the --enable-gcov configure option to setup those options
correctly. We also add a make target called check-coverage,
which runs the unit tests, runs gcov and uploads the data to
the codecov.io cloud service for display.
Finally, we include a Dockerfile-coverage which creates a
container image in alpine linux to run the tests. To create
the image:
$ docker build \
--build-arg commit=`git rev-parse HEAD` \
--build-arg token=<upload token from codecov.io> \
-t frr-gcov:latest \
-f docker/alpine/Dockerfile-coverage .
and to create and upload the report:
$ docker run -it --rm frr-gcov:latest

This is an implementation of PBR for FRR.
This implemenation uses a combination of rules and
tables to determine how packets will flow.
PBR introduces a new concept of 'nexthop-groups' to
specify a group of nexthops that will be used for
ecmp. Nexthop-groups are specified on the cli via:
nexthop-group DONNA
nexthop 192.168.208.1
nexthop 192.168.209.1
nexthop 192.168.210.1
!
PBR sees the nexthop-group and installs these as a default
route with these nexthops starting at table 10000
robot# show pbr nexthop-groups
Nexthop-Group: DONNA Table: 10001 Valid: 1 Installed: 1
Valid: 1 nexthop 192.168.209.1
Valid: 1 nexthop 192.168.210.1
Valid: 1 nexthop 192.168.208.1
I have also introduced the ability to specify a table
in a 'show ip route table XXX' to see the specified tables.
robot# show ip route table 10001
Codes: K - kernel route, C - connected, S - static, R - RIP,
O - OSPF, I - IS-IS, B - BGP, P - PIM, E - EIGRP, N - NHRP,
T - Table, v - VNC, V - VNC-Direct, A - Babel, D - SHARP,
F - PBR,
> - selected route, * - FIB route
F>* 0.0.0.0/0 [0/0] via 192.168.208.1, enp0s8, 00:14:25
* via 192.168.209.1, enp0s9, 00:14:25
* via 192.168.210.1, enp0s10, 00:14:25
PBR tracks PBR-MAPS via the pbr-map command:
!
pbr-map EVA seq 10
match src-ip 4.3.4.0/24
set nexthop-group DONNA
!
pbr-map EVA seq 20
match dst-ip 4.3.5.0/24
set nexthop-group DONNA
!
pbr-maps can have 'match src-ip <prefix>' and 'match dst-ip <prefix>'
to affect decisions about incoming packets. Additionally if you
only have one nexthop to use for a pbr-map you do not need
to setup a nexthop-group and can specify 'set nexthop XXXX'.
To apply the pbr-map to an incoming interface you do this:
interface enp0s10
pbr-policy EVA
!
When a pbr-map is applied to interfaces it can be installed
into the kernel as a rule:
[sharpd@robot frr1]$ ip rule show
0: from all lookup local
309: from 4.3.4.0/24 iif enp0s10 lookup 10001
319: from all to 4.3.5.0/24 iif enp0s10 lookup 10001
1000: from all lookup [l3mdev-table]
32766: from all lookup main
32767: from all lookup default
[sharpd@robot frr1]$ ip route show table 10001
default proto pbr metric 20
nexthop via 192.168.208.1 dev enp0s8 weight 1
nexthop via 192.168.209.1 dev enp0s9 weight 1
nexthop via 192.168.210.1 dev enp0s10 weight 1
The linux kernel now will use the rules and tables to properly
apply these policies.

Linux has the ability to support a concept of 'realms'.
This concept allows you to mark routes with a realm id
value of 1-255. If you have marked the realm
of a route then you can use the tc program to
apply policy to the routes.
This commit adds the ability of FRR to interpret
a tag from (1-255) as a realm when installing into
the kernel. Please note that at this point in time
there is no way to set policy from within FRR. This
must be done outside of it.
The normal methodology for setting tags is valid here
via a route-map.
Finally this is only applied if the --enable-realms configure
option is applied.

This also fixes a build problem where using #include

having both
ldp_vty_cmds.c: ldp_vty_cmds_clippy.c
ldp_vty_cmds.c: ../ldpd/ldp_vty_cmds_clippy.c
(because, if it's included as "ldpd/..", it uses the "-I.." include path
in gcc, so the gcc -MD dependency output is "../ldpd/...")
... all of which causes the build to try to build it twice (at the same
time) and fail rather stupidly.

zebra.h includes route_types.h, which means almost all of our Makefile
targets have a dependency on route_types.h. While BUILT_SOURCES ensures
that this dependency is fulfilled on a "make all", this doesn't work
when building specific targets (e.g. "make lib/libfrr.la").
There seems to be no good way to add a dependency on everything, so the
best fix for this is to just generate the file during ./configure.
(The Makefile rule is still there, so if route_types.txt is changed,
route_types.h will be rebuilt.)
This only affects "initial" builds from a clean directory and/or builds
with --disable-dependency-tracking; other than that gcc will output
Makefile dependencies during compilation so that route_types.h will
become a dependency for all output files.
gitversion.h has the same problem on a smaller scope.
command_lex.h & command_parse.h *don't* have the problem because they're
only used in specific files, and these files have the dependency
explicitly listed in the Makefile. Hence, they can also be removed from
BUILT_SOURCES.

This feature adds an L3 & L2 VPN application that makes use of the VPN
and Encap SAFIs. This code is currently used to support IETF NVO3 style
operation. In NVO3 terminology it provides the Network Virtualization
Authority (NVA) and the ability to import/export IP prefixes and MAC
addresses from Network Virtualization Edges (NVEs). The code supports
per-NVE tables.
The NVE-NVA protocol used to communicate routing and Ethernet / Layer 2
(L2) forwarding information between NVAs and NVEs is referred to as the
Remote Forwarder Protocol (RFP). OpenFlow is an example RFP. For
general background on NVO3 and RFP concepts see [1]. For information on
Openflow see [2].
RFPs are integrated with BGP via the RF API contained in the new "rfapi"
BGP sub-directory. Currently, only a simple example RFP is included in
Quagga. Developers may use this example as a starting point to integrate
Quagga with an RFP of their choosing, e.g., OpenFlow. The RFAPI code
also supports the ability import/export of routing information between
VNC and customer edge routers (CEs) operating within a virtual
network. Import/export may take place between BGP views or to the
default zebera VRF.
BGP, with IP VPNs and Tunnel Encapsulation, is used to distribute VPN
information between NVAs. BGP based IP VPN support is defined in
RFC4364, BGP/MPLS IP Virtual Private Networks (VPNs), and RFC4659,
BGP-MPLS IP Virtual Private Network (VPN) Extension for IPv6 VPN . Use
of both the Encapsulation Subsequent Address Family Identifier (SAFI)
and the Tunnel Encapsulation Attribute, RFC5512, The BGP Encapsulation
Subsequent Address Family Identifier (SAFI) and the BGP Tunnel
Encapsulation Attribute, are supported. MAC address distribution does
not follow any standard BGB encoding, although it was inspired by the
early IETF EVPN concepts.
The feature is conditionally compiled and disabled by default.
Use the --enable-bgp-vnc configure option to enable.

Infrastructure that allows protocol buffers to be used in Quagga. The
changes below comprise of:
- Build hooks
- Protobuf definitions for common types.
- Library routines for working with protobuf, including functions
that help translate between common quagga types and their protobuf
equivalents.
Changes:
* qpb/{Makefile.am,README.txt,qpb.h,.gitignore}
Add the qpb library, which provides shared code and definitions
for using protocol buffers in quagga code.
* qpb/qpb.proto
Protobuf definitions that can be shared by all of quagga.
* qpb/linear_allocator.h
An allocator that allocates memory by walking down towards the end
of a buffer. This is used to cheaply allocate/deallocate memory on
the stack for protobuf operations.
* qpb/qpb_allocator.[ch]
Thin layer that allows a linear allocator to be used with the
protobuf-c library.
* common.am
This is an automake fragment that is intended to be shared by
Makefile.am files in the tree. It currently includes definitions
related to protobuf.
* configure.ac
- Add logic to optionally build protobuf code.
By default, protobuf support is enabled if the protobuf C
compiler (protoc-c) is available, and the associated header
files/library can be found.
The user can choose to override this behavior via the new
--disable-protobuf/--enable-protobuf flags.
- Include the quagga protobuf library (qpb) in the build.
* .gitignore
Ignore source code generated by protobuf compiler.
* Makefile.am
Add 'qpb' to the list of subdirectories.

We realize VRFs with linux netns by default. The main job is
to associate a VRF with a netns. Currently this is done by
the configuration:
[no] vrf N netns <netns-name>
This command is also available in vtysh and goes to only
zebra, because presently only zebra supports multiple VRF.
A file descriptor is added to "struct vrf". This is for the
associated netns file. Once the command "vrf N netns NAME"
is executed, the specified file is opened and the file
descriptor is stored in the VRF N. In this way the
association is formed.
In vrf_socket(), we first switch to the specified VRF by
using the stored file descriptor, and then can allocate
a socket which is working in the associated netns.

When static linking is used, the order of the libraries is important,
and the libraries using a symbol from another library should be listed
*before* the library providing that symbol (see
http://eli.thegreenplace.net/2013/07/09/library-order-in-static-linking)
for details.
When vtysh is linked statically, the command line contains "-lcurses
-lreadline", which causes a build failure due to unresolved
symbols. This is because readline is using symbols from the curses
library: the order should be the opposite.
This patch fixes that problem by putting the -lreadline at the
beginning of the LIBREADLINE variable calcualted by the configure
script.

This patch implements the 'update-groups' functionality in BGP. This is a
function that can significantly improve BGP performance for Update generation
and resultant network convergence. BGP Updates are formed for "groups" of
peers and then replicated and sent out to each peer rather than being formed
for each peer. Thus major BGP operations related to outbound policy
application, adj-out maintenance and actual Update packet formation
are optimized.
BGP update-groups dynamically groups peers together based on configuration
as well as run-time criteria. Thus, it is more flexible than update-formation
based on peer-groups, which relies on operator configuration.
[Note that peer-group based update formation has been introduced into BGP by
Cumulus but is currently intended only for specific releases.]

libexecinfo is used to provide backtrace() on *BSD. The API is

To improve configure behaviour, the following configure options are
modified/introduced:
* --enable-gcc-rdynamic now defaults to "on" if the compiler is gcc.
(I sadly wasn't able to find any documentation on the availability of
this option for llvm, even though at least the version I have
installed does support it)
* --enable-backtrace has been added. This behaves as off/auto/on
switch, i.e. giving either {dis,en}able will result in the requested

Quagga makes bad assumptions about sockaddr_dl (on NetBSD, but possibly
on other systems as well). Particularly, sizeof(struct sockaddr_dl)
returns a size that does not include the full sdl_data field, leading to
not enough data being copied. This breaks IPv6 RAs in particular, as
a broken mac address from sockaddr_dl will be included in the packets.

these days. But, anyhow, the warnings disabled in Quagga's configure.ac
don't seem to appear anywhere at all, so let's just remove the option
completely.

If enabled with --with-pkg-gitversion on ./configure, this will append
git version strings and branch information at the following places:
- overall version number: 0.99.21-g0123456
- login motd and show version: tag information + git id + branches
Sample output:
Hello, this is Quagga (version 0.99.21-g14b49ad-dirty).

Enhance zebra to send routes to the (optional) Forwarding Path Manager
component using the interface defined by fpm/fpm.h.
* configure.ac
- Add --enable-fpm flag.
The FPM-related code in zebra is activated only if the build is
configured with '--enable-fpm'.
- Add HAVE_NETLINK automake conditional.
This allows us to conditionally build netlink-dependent C code.
* zebra/{rib.h,zebra_rib.c}
- Add the 'fpm_q_entries' field to the rib_dest_t structure. This
allows dests to be placed on the fpm queue.
- Define a couple new rib_dest_t flags that hold FPM-related
state.
- Invoke the zfpm_trigger_update() function for a route_node
whenever the information to be sent to the FPM changes.
- rib_can_delete_dest(): Return FALSE if we have to update the FPM
about the given dest. This ensures that the dest is not deleted
even if there are no ribs hanging off of it.
* zebra/zebra_fpm.c
This file holds most of the code for interacting with the FPM.
- If quagga was configured with '--enable-fpm', periodically try
to connect to the FPM.
- When the connection comes up, enqueue all relevent dests to the
FPM queue.
- When the FPM socket is readable, dequeue the next rib_dest_t
from the FPM queue, encode it in to a message and send the
message to the FPM.
- When the connection to the FPM goes down, remove all dests from
the FPM queue, and then start trying to connect to the FPM
again.
- Expose the following new operational commands:
show zebra fpm stats
clear zebra fpm stats
* zebra/zebra_fpm_netlink.c
- zfpm_netlink_encode_route(): Function to encode information
about a rib_dest_t in netlink format.
* zebra/zebra_fpm_private.h
Private header file for the zebra FPM module.
* zebra/zebra_fpm.h
Header file exported by zebra FPM module to the rest of zebra.
* zebra/debug.c
Add the 'debug zebra fpm' command.
* zebra/main.c
Initialize the zebra-FPM code on startup.
* zebra/misc_null.c
Add stub for zfpm_trigger_update().
* zebra/Makefile.am
- Include new file zebra_fpm.c in build.
- Include zebra_fpm_netlink.c in build if HAVE_NETLINK is defined.
* vtysh/Makefile.am
Include zebra_fpm.c in list of files that define cli commands.

ifi_link_state missing in OS X. There could be other *BSD's that haven't
implemented it and possibly affects older implementations.
The existing HAVE_BSD_LINK_DETECT configure.ac check is only confirming
the link state detection using ifmediareq.ifm_status found in
<net/if_media.h>. This is the link state detection used in
zebra/ioctl.c. Later, *BSD redefined struct if_data in <net/if.h> and
included link state detection. This is the method used in
zebra/kernel_socket.c
Additional test defined in config.ac to test for member struct
if_data.ifi_link_state defined in <net/if.h> separate from test for
<net/if_media.h> ifmediareq.ifm_status
Fixed #ifdef's in zebra/kernel_socket.c to use the new #define
No impact on older function calls in zebra/ioctl.c
Tested on 64bit OS X 10.7, FreeBSD 9.0 amd64 & i386 (32bit)
using gcc & clang. Tested on linux 64bit.

Broke the tests again... let's just build them by default so it's easier
to notice. If anyone doesn't want to build tests, there's
--disable-tests.

This change adds a --with-pkg-extra-version option to ./configure to allow
packagers and distributions to fine tune the version displayed to the end
user to assist in support. It is also very useful when reporting bugs on
the official Quagga mailing lists.
There are two ways of utilsing this functionality:
a) ./configure --with-pkg-extra-version=-wmo1
b) EXTRAVERSION=-wmo1 ./configure
The latter is a common way for many distributions to add extra version
strings to signify their own patch level to a given package.
Also, minor whitespace fix in configure summary.

--enable-snmp will enable AgentX support in Quagga. SMUX is still here
and can be enabled with --enable-snmp=smux. AgentX support can be
enabled with "agentx" in configuration file. As for SMUX, this command
is not understood by vtysh. It can be disabled with "no agentx",
though there is no real use of this since this command cannot be used
with vtysh.
If "agentx" and "no agentx" command were added to vtysh, it would not
be possible to disable agentx support after enabling it because
NetSNMP does not expose the appropriate methods for this.
The internals of AgentX are hidden by NetSNMP. Therefore, we don't
have a file descriptor to add to the threading system. We do not have
the timers to set either. Therefore, the event loop is modified to
make use of snmp_select_info() from NetSNMP.
Traps are not supported yet.
The correct method to link to NetSNMP is to use net-snmp-config (which
is like pkg-config). Explicit link to libcrypto is also dropped
(NetSNMP libs are linked to libcrypto, no need to link Quagga to
it). Moreover, @SNMP_INCLUDES@ is dropped because useless. Due to a
bug in configure.ac, it was properly populated.
* Initial import of the Babel routing protocol, ported to Quagga.
* LICENCE: Update the original LICENCE file to include all known potentially
applicable copyright claims. Ask that any future contributors to babeld/
grant MIT/X11 licence to their work.
* *.{c,h}: Add GPL headers, in according with the SFLC guidance on
dealing with potentially mixed GPL/other licensed work, at:
https://www.softwarefreedom.org/resources/2007/gpl-non-gpl-collaboration.html
* configure.ac: Check for latexmk and pdflatex
* Makefile.am: Add a conditional target to build HACKING.pdf, as a convenience
* HACKING.tex: A slightly more structured HACKING, is readable on its own.
* HACKING: removed
MALLOC/REALLOC aren't used properly (no rpl_malloc), remove them
while at it, infer some sane ipforwarding method from the OS value.
(v2 on that, "==" is not a proper operator for standard "test")
(This commit is based on the patch from BZ#420, and should fix that bug.)
* configure.ac: detect availability of that API
* sockopt.c (setsockopt_ipv4_multicast): use it for join/leave IPv4
multicast groups
This change is based on Xavier Beaudouin's patch (which fixes detection
of 3 config.h macros on FreeBSD without any impact to Linux build of
Quagga) and FreeBSD port patch (which fixes 5 config.h macros, but
breaks the Linux build), it fixes 5 macros and works for both FreeBSD 8
and Linux.
In deciding whether to default ospfapi to on or off, use the same rule
for opaque-lsa as earlier: != no rather than = yes, so that not having
set it implies yes.
* configure.ac: (AC_ARG_ENABLE({ospf-te,opaque-lsa})) reverse the sense to
--disable
(enable_{opaque_lsa,ospf_te}) treat as enabled unless explicitly disabled.
this fixes warnings from vtysh extract.pl by making sure the isis method
files always 'work'. (previously, extract.pl would grab unselected isis
method sources and then complain about missing headers)
* configure.ac: Move down the AC_SYS_LARGEFILE test - it was setting CFLAGS
and so disabling the default CFLAGS setting section.
Squish warning by adding AC_CONFIG_MACRO_DIR on the reccommendation of
autoreconf.
Configure option "--disable-doc" will prevent building
the documents under doc. Saves build time and the need to
have document building tools installed. Useful when your build
machine is different from your development machine.
It also prints what were comments explaining why gawk is necessary, and
not-in-PATH to help user figure out why it's not found.
Build was mysteriously failing with the old version of this check when gawk
wasn't installed.
It wasn't used, and the code wasn't printing progress or the result in some
cases. the test uses minimal resources, so it's probably better to not
cache so as to avoid inconsistencies if --with-prefix or directory variables
are changed between ./configure runs.
Fix zebra_rtread and zebra_ipforward_path.
It looks like someone tried to make this cached, but it was being ignored at
least on autoconf 2.6.1. 2.6.2 now gives a warning about the situation,
hence this fix.
Although they are just warnings, it's dangerous to leave them as-is, because
someone not diligent in reading the autoconf manual might just stick _cv_ in
the name, with the effect that running a ./configure --config-cache would
fail horribly, since variables are being set inside the AC_CACHE_CHECK()
block that would not be seen when the variable's value was read from cache.
Also added m4 quotes [] to macro arguments as autoconf manual
suggests.
AC_AIX and AC_GNU_SOURCE conflict > autoconf 2.53 or so,
but the replacement AC_USE_SYSTEM_EXTENSIONS isn't available
until later versions. So either we narrow the supported
autconf version range, or disable AIX (if it has any effect),
or determin that AC_AIX doesn't do anything useful anyhow.
Debian tried unsuccessfully to build with libpcreposix. This adds proper
support to autoconf/configure.ac for it.
Based on the patch by C.J. Adams-Collier in bug #483.
bgpd/bgp_{regex,routemap}.h: Pull in PCRE POSIX header if available.
* configure.ac: Check for the actual CLOCK_MONOTONIC symbol, as clock_gettime
need not imply that clock type is supported
* lib/zebra.h: use the method given in autoconf docs for sys/time.h
inclusion
Quagga has code to support monotonic clock to avoid issues where
time of day changes. The support was incomplete since it was not being
detected by autoconf.
* configure.ac: Add a --enable-linux24-tcp-md5 argument, to compile in
support for the old TCP-MD5 patch for Linux 2.4 systems. This overrides
auto-detection of TCP-MD5 supported by the target system.
* lib/sockopt.c: (sockopt_tcp_signature) add in a variant for the old
Linux 2.4, TCP_MD5_AUTH variant of TCP-MD5 support, conditional
on the previous configure arg.

* configure.ac: If netlink is available, then that is how the
initial routes and interfaces should be read, rather than through
/proc, so don't set IF_PROC.
