Ships the p0f v2.0.8 signature database for passive + active OS fingerprinting. 375 total signatures across four probe contexts: - p0f.fp (262 sigs) — passive SYN fingerprints - p0fa.fp ( 61 sigs) — SYN-ACK response, for active probes - p0fr.fp ( 46 sigs) — RST response quirks - p0fo.fp ( 6 sigs) — "stray" packet fingerprints Replaces reliance on the 10-signature hand-rolled p0f-lite table in decnet/sniffer/p0f.py for any match job the upstream DB covers. Keeping the hand-rolled table as a fallback for modern kernels the v2 DB pre-dates — v2 froze in 2006 so post-Win10 / post-Linux-3.x kernels won't match against upstream directly. DECNET-authored additions will go in a sibling p0f-decnet.fp under GPLv3 (not yet committed; added as the ingester observes real honeypot traffic). Provenance (full chain in data/README.md): - Source: Debian snapshot of p0f_2.0.8.orig.tar.gz - SHA1 matches Debian-recorded 7b4d5b2f24af4b5a299979134bc7f6d7b1eaf875 - Files byte-identical to upstream tarball (verified by hash) License chain: - Upstream: LGPL-2.1 (doc/COPYING preserved verbatim as data/LICENSE.p0f-upstream, Michal Zalewski's copyright intact). - DECNET uses the LGPL-2.1 §3 explicit permission to convert to any version of the GPL. These files, as consumed in DECNET, are effectively GPL-3.0. Chain documented in data/README.md so an auditor sees the full reasoning. - LGPL-2.1 → GPL-3.0 §3 conversion is a settled compat path; same mechanism the kernel uses for LGPL userland glue and many other projects apply daily. Rejected path — nmap-os-db under NPSL — because NPSL adds restrictions GPLv3 §7 prohibits us from accepting. An email is out to Fyodor requesting an open-source-author exception grant, but we don't block on it: p0f v2 is a genuine accuracy improvement in its own right, and adding nmap-osdb later (if granted) plugs into the same provider interface with zero refactor. Directory layout mirrors the established provider-subpackage pattern (see decnet/geoip/, decnet/bus/) per the feedback_provider_ subpackages memory: base + factory + impl/ subpackages, no flat files. Parser + matcher + factory wiring land in the next commit sequence.
