I've been sitting on a change for a while that I don't think upstream can take. https://people.freebsd.org/~bdrewery/patches/tcpdump-pflog-uid.diff is a version of the patch. I'm not sure if it was my final one. I would need to test again before committing. The problem is that pf is implemented differently on FreeBSD and OpenBSD for pid/uid tracking. The code would be overly complex to support both and I gave up on that. Even getting it to work on FreeBSD required the _KERNEL define hack for UID_MAX, which our pf uses to note 'no uid value'= =2E I was considering committing this, but was not sure on the proper way to note our changes. #if __FreeBSD__ was my guess. --=20 Regards, Bryan Drewery --7nDBmtWcjCl8qesb10bInepqjvnEH8VCo Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBAgAGBQJU09cDAAoJEDXXcbtuRpfPceIH/RoWKyUkWIc6nwG4o6L/sIxH ceQLrN9PKObZ2DQfWKKL069xk2J0XZZrxfjHaR+fdWWRcfT+TYIAOiOijpGmp9D7 O28dbZL0byPeVye/6ySlbV7VtL6i98v6dEUiTpHebeYYuGWmmZQCFLVIe+AVRlc7 wgU0svS0v0psg5YVsfTHz2mqm6SAimJWmCi37dViKkjWEXmo75X+/cm5s2cLCU1+ u7CGBMoLRleRX330+d92jHrvzH0SL0u930q4s/X/Oj8LZTeAk3pBt/4dU9RGYF76 BG1IlaJMjtoYAdXduSRTm+fFbK0nKvgCX6f2P5cYVfx5upagxDuzij57NDPl7Bw= =9T/E -----END PGP SIGNATURE----- --7nDBmtWcjCl8qesb10bInepqjvnEH8VCo--
