Package: quagga
Version: 0.99.1-3
Severity: normal
I have a laptop, connected via VPN over wireless to a desktop,
connected via Ethernet to a local Internet gateway, who is then
connected via VPNs to two other Internet gateways. All gateways, plus
the desktop and laptop, are a part of an area-0 OSPF network. The
three gateways all broadcast a 0.0.0.0 default route, as well as their
own internal networks.
On my laptop, after upgrading to 0.99, I am no longer able to see any
routers beyond the local Internet gateway. Their routes do not show
up in my routing table, nor do the routers themselves show up in the
"OSPF router routing table" section of "show ip ospf route". As far
as my OSPF daemon is concerned, the OSPF network ends there. (All
other routers can see each other fine.)
The exact same effect occurs if I upgrade Quagga on the desktop
(that connects my laptop to the local Internet gateway).
I was unable to determine if the broadcasting default (0.0.0.0) routes
was part of the problem or not, because by the time I had disabled
this, the desktop's ospfd had begun to segfault less than a minute
after startup:
OSPF: Received signal 11 at 1127774329 (si_addr 0x200a, PC 0xb7f40cf7);

I've had to downgrade to 0.98.3 for now.
Should I be taking this to the Quagga mailing list? Figured I'd post
here first in case there had been a Debian-specific change.
