bird6 spontaneous crash
Hello, in our testing environment I experienced two strange spontaneous crashes with bird6 1.2.3, running on debian 5.0.5 (amd64). The binary is from build-ipv6 directory of a debian build and with symbols (unstripped). I've got here: bird6-binary, two coredumps, loglines, logfiles and the config. May I ask for somebody of the developers team to take a look at those files? Thank you and best regards Robert -- www.vix.at | www.aco.net robert.wein@univie.ac.at Vienna University Computer Center

Thanks, fixed. You can use the attached patch to fix the problem.

Thank you! Just made the new binary. If something unexpected happens, I'll report back. br Robert -- www.vix.at | www.aco.net robert.wein@univie.ac.at Vienna University Computer Center

Probably everyone using IPv6 BGP with more than ~ 500 routes. When an update packet with many prefixes is prepared in a TX buffer, a last prefix added to the packet might overwrite the end of the buffer (only if the prefix is longer than /32). -- Elen sila lumenn' omentielvo Ondrej 'SanTiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
