This piece of code causes all Quagga routers on a broadcast link to
send a HELLO packet simultaneously if they see a new neighbor. It also
resets the HELLO timer, so all the quagga routers will continue to
send HELLO packets simultaneously in the future. This is not good
(especially on networks with a lot of Quagga routers connected), and
is explicitly discouraged by the OSPF standard, RFC 2328 (chapter
4.4.Timers).
I suggest to remove the code snippet, it does not provide much benefit
anyway.

Adds "ipv6 nd router-preference (high|medium|low)" and
"no ipv6 nd router-preference" interface commands.

* doc/Makefile.am: arguments for the 'convert' programme seem to have
changed incompatibly at some stage - just remove the problematic -dither.
|
|
|
|
* bgp_vty.c: BGP_UPDATE_SOURCE_STR define should only specify IP addresses,
the underlying mechanisms won't do anything useful with interface names.
Fix bug #527.

Should probably have AC_TYPE_UINT16_T in configure.ac to make it really
clean... and a fresh import of gnulib, the existing copy of gnulib seems to
be manually put some stuff in zebra.h. I'm leaving that alone for now,
since a fresh import will probably clean up a lot of cruft and it would be a
duplicated effort to fix some things now.
The FreeBSD port 0.99.11_1 files/patch-ospfd-ospfd.h can probably go away
after this is applied.

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.

autoscan 2.62 complains about bzero(), so a good fix
nowadays is to just replace it.
|
|
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.
|
|
Some uses of GNU make extensions were not necessary. There are still some,
but they might exist as workarounds for older versions of autoconf that have
since been solved.
Lesson learned: implicit target rules have opposite order to pattern target
rules.

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.

* */*main.c: Seems that the actual code was removed previously, but the
argument processing code remained.

Expansion of Ubuntu quagga-0.99.11-1 30_doc__ospfd.8__nolog.dpatch
|
|
* 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.

Check result of daemon() call to fix warning
Make local variables static
|
|

|
|
|
Avoid bugs, and improve cache locality by allowing message lists
to be read/only.
|
|
Fix printf format warning and make capability table 'const static'
|
|
smux_trap and oid_copy should allow read-only source.
|
|
Message lists can be read-only, and hash tables are local to this
code.
|
|
The finite state machine table is immutable.

When a BGP instance is deleted with lots of routes and neighbors
it is possible for the peer rsclient queue to run after
bgp_delete has been called. This would lead to bgpd crashing,
see https://bugzilla.vyatta.com/show_bug.cgi?id=3436
The fix is to add reference counting to the BGP instance and defer
actual freeing until all references are gone.
This patch also fixes a memory leak where the self-reference
peer instance was being created but never freed.
The check in bgp_clear_route is no longer valid because it is possible
for it to be called when peer is in Deleted state during cleanup.
|

These variables are const.

Don't need big buffer 1024 to hold IPV4 (INET_ADDRSTRLEN)
or IPv6 (INET6_ADDRSTRLEN) message.

Vyatta Bug 3999
|
|
When BGP crashes, sometimes all we get to see is syslog.
|
|
An external user was building on system without IPv6 and
it wouldn't work.
|
|
Don't need command twice.
|
|
ospf6d will crash if attempting to remove interface when no areas have been
defined Check if any areas have been defined. Should prevent use of empty
pointer.
|
|
ospf6d will crash if this command is executed on a non-border-router.
Included test to verify that any routes are defined, preventing empty
pointer from being used.
|
|
Suggestion: Makes no sense to me that the statement to remove ospf6
configuration is located in OSPF6D_NODE.
Moved to CONFIG_NODE next to matching define command.
|
|
ospf6d will crash if the same range is defined twice.
There was no check if the same range had previously been defined,
thereby causing a later assert to fail.
|
|
This may fix vyatta BUG 3096. The reference count for OSPF route table was
never completely freed on deleting all neighbors.
|
|
Need to check both IFF_UP and IFF_RUNNING if link-detect is enabled,
before announcing routes.
|
|
The MTU data in the netlink message is always unsigned 32 bits.
Don't use integer.
|
|
|
|
Do some cleanup work on recently added meta-queue code:
* use table rather than switch
* indent with quagga standard indentation
* since meta_queue_new is only used at initialization
allocation failure should be fatal.
|
|
Add more prototypes and make some functions static
