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.

Some .h files in lib/ are autogenerated. The search path should
include the build directory and the source directory. They usually
match but sometimes, they may be different. For example:
$ mkdir build
$ cd build
$ ../configure
$ make

* Makefile.am: vtysh should also pull in commands from zebra_routemap.c

* configure.ac: add a configure flag and autoconf macro, which will
determine if your toolchain supports PIE.
* */Makefile.am: add corresponding CFLAGS and LDFLAGS into
appropriate places.

procedure. Define vtysh_cmd_FILES. Use EXTRA_DIST.

* Makefile.am: remove zebra/irdp.c from list - dead.
* extract.pl.in: Substitute in the autoconf srcdir/builddir paths
for includes to cpp.
|

* Makefile.am: extract.pl isnt in srcdir, it's always in the
builddir.
* extract.pl.in: match on end of filenames, filename could contain
various preamble due to out of tree builds.

* */Makefile.am: Use ../dir/libfoo.la, rather than "-L../dir
-lfoo", to avoid linking against installed libraries from a
previous version.
* {lib,ospfd,ospfclient}/Makefile.am: explicitly define the shared
library version number to be 0.0
* configure.ac: remove spurious , so extract.pl is chmod'd +x.
* HACKING: explain shared library versioning rules

libzebra and libospfapiclient are now built shared, and linked shared
with the daemons. This reduces the memory needed when running
multiple daemons; each daemon is at least 150k smaller. Static
libraries are still built, and libtool should use them on platforms
which don't have shared libaries. As with autoconf, the user of a
distribution does not need libtool; one just needs that to build from
CVS.
libospf.a is still a non-shared library, and still installed, not
because that makese sense, but because I don't understand why it is
the way it is now.
Note that the tree was tagged 'libtool-before' just before this commit.

if --enable-vtysh, look for perl, and substitute into vtysh/extract.pl,
rather than assuming perl is in /usr/bin
Look for tputs in libtermcap and libcurses, in addition to
previously-searched locations. Follow GNU readlines search order.
Clean up --enable-vtysh definition in configure.ac.
Add vtysh/vtysh_cmds.c to CLEANFILES. This is important if
extract.pl fails, so that 'make clean && make' will regenerate
vtysh_cmds.c rhather than using the old zero-length file.

files, defaulting to sysconfdir (matching previous behavior).
This is needed to support (cleanly) NetBSD pkgsrc, which requires that
example config files go in $(prefix)/share/examples/pkgname, rather
than in $(prefix)/etc/pkgname.

* vtysh/Makefile.am: vtysh_cmd.c rebuild was broken because it
depended against source files without specification, i.e. it
used ../zebra instead of $(top_srcdir)/zebra.
|
|
* vtysh/Makefile.am: do not include vtysh_cmd.c in dists, its
configure dependent. (still need to find a way to make building of
it dependent on configure options or include all commands.)
|
|
* vtysh/Makefile.am: explicitely list the files required for
vtysh_cmd.c to be generated, to minimise spurious rebuilds.

same idea as in lib/distribute.c to allow extract.pl to pick up commands
for vtysh.

http://hasso.linux.ee/zebra/ht-distribute-18042003.patch
Allows to extract.pl to pickup "distribute-list ..." commands for vtysh
(ripngd and ripd).

Add dependency on rebuild target for vtysh_cmd.c to Makefile.am
