Hello all.
tcpdump has been keeping a copy of bpf_dump.c from libpcap with the
following description in INSTALL.md:
"bpf_dump.c - BPF program printing routines, in case libpcap
doesn't have them. A known example is OpenBSD libpcap."
Indeed, OpenBSD libpcap still does not have bpf_dump(). However, in
the master branch tcpdump(1) says:
"This version of tcpdump requires libpcap 1.0 or later."
bpf_dump() has been in libpcap since version 0.6.1, so according to the
above any supported version of libpcap has bpf_dump().
This way, either bpf_dump.c should be removed from tcpdump to match the
stated version requirement (which would exclude OpenBSD libpcap) or the
version requirement should be worded differently. Alternatively,
someone could add bpf_dump() to OpenBSD libpcap, which would simplify
OpenBSD tcpdump as well, because it includes a copy of bpf_dump.c too.
