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.

Newer MacOSX versions have support for both IPv6 advanced socket API
RFCs (2292 and 3542) switchable in compile time, but neither of these
is default for some strange reason. RFC3542 will be default in future,
but for now we have to declare that we want to use the RFC3542 API
before including <netinet/in.h>.

Measuring the resource usage of threads is moderately expensive
since it requires doing an additional system call everytime a
thread context switches. Make it possible to disable this with
a configuration option.

LLVM clang does not support #pragma weak (bug 3679) on OS X. There are
other systems where the #pragma weak has varying syntax.
Added m4 file from the autoconf archives:
http://www.gnu.org/software/autoconf-archive/ax_sys_weak_alias.html
Fix up zebra/*_null.c files to use #pragma weak alias or stub functions
if not available. It's incomplete in that the different format #pragma
enable easier fixes on need.
Tested on 64bit OS X 10.7, FreeBSD 9.0 amd64 & i386 (32bit) using
gcc & clang. Tested on linux 64bit.

Intel's icc doesn't accept "-wd <number>" anymore, it's "-wd<number>"
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).
Copyright 1996-2005 Kunihiro Ishiguro, et al.
This is a git build of quagga_0_99_21_release-106-g14b49ad-dirty
Associated branch(es):
local:master
[v2]: fix build without gitinfo (add "else" branch)
[v2]: fix for repos without any tags (different git describe output)

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.

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.
|
|
NetSNMP is the only SNMP implementation for Quagga. We don't need two
different symbols.

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

Configure option "--disable-doc" will prevent building

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
