The first test sent tcpdump into an infinite loop because the l2tp_avp_print() function calls itself and passes bad data. uP: i386 tcpdump: (up to 3.8.1) libpcap: 0.7.2 os: Linux I have not been able to seg fault tcpdump on OpenBSD. And, the infinite looping does not occur on OpenBSD after applying Otto Moerbeek's patch. Can anyone else reproduce these results?
this patch should solve, please apply -- mydecay S.P.I.N.E. Group - http://www.spine-group.org Key Fingerprint: 667A 4E73 EA53 66AC E2AB D0CA 2908 1484 1F26 4C40 GnuPG Key: http://www.spine-group.org/keys/mydecay.asc
