| H A D | bpf.c | diff 162641 Mon Sep 25 23:02:02 MDT 2006 brooks It is possible for bpf to return a length such that: length != BPF_WORDALIGN(length) This meeans that it is possible for this to be true: interface->rbuf_offset > interface->rbuf_len Handle this case in the test for running out of packets. While OpenBSD's solution of setting interface->rbuf_len to BPF_WORDALIGN(length) is safe due to the size of the buffer, I think this solution results in less hidden assumptions. This should fix the problem of dhclient running away and consuming 100% CPU. PR: bin/102226 Submitted by: Joost Bekkers <joost at jodocus.org> MFC after: 3 days |
