Below you can find the next draft revision. It incorporates some
feedback received from Guy and Michael, also it reorders the TLVs and
adds SnapLen TLV, Netmask TLV and EOF TLV. Also the text has been
converted to a man page, so it could live next to

Hello all.
The last CI build of the libpcap-1.10 branch failed on netbsd-aarch64
because the latter now uses GCC 12. Commit 4e7f6e8 makes a lazy fix
for that in the master branch; if a more sophisticated solution is not
required, a simple cherry-pick into libpcap-1.10

improvements can be made there when and as necessary. Changes from the

A while ago I tried to comprehend a few BPF-related bug reports in
libpcap and found it difficult to follow the logic of filter
compilation and optimization. On one hand, there is the universally
available, but basic "tcpdump -d" pseudocode listing. On the

Thank you. The signed device index hinted at some logic error, but I
didn't understand if it required a more sophisticated fix.

Below you can find a digest of some works done on the CI infrastructure
during past few months.
First of all, the illumos-amd64 Buildbot worker has been replaced. It
used to be an OpenIndiana VM from a commercial hosting provider.

a userspace process when it tries to perform an unaligned memory

tcpslice 1.6 has been released with the following change log. Thanks
to everyone who contributed!
- Call pcap_dump_close() on the output file.
- Implement new flags in ./configure: --enable-instrument-functions,
--without-libnids, --without-libosipparser2

I hope this finds you well. Below you can find a digest of the CI
infrastructure works since the previous update.

illumos-amd64 now uses Clang 15.0 (was 11.1).

Hello list.
Unless anyone objects, the next release of tcpslice (1.6) will be made
soonish to flush the few buffered minor bugfixes and to take another
item off my to-do list.

As it turns out, on Linux tcpslice currently fails to build with the
current master branch of libpcap. This reproduces in all Linux CI
builds and also on my Ubuntu 20.04 PC. The root cause seems to be in
libpcap via pcap-config:
/usr/bin/ld: cannot find -lsystemd
