From e407216449fd52f8346143146cb0de3322de93f0 Mon Sep 17 00:00:00 2001 From: sthen Date: Sun, 3 Dec 2017 20:40:04 +0000 Subject: [PATCH] Disallow the _pbuild user from making TCP/UDP connections in the default PF ruleset. This is not a complete block on _pbuild being able to communicate (e.g. non-TCP/UDP protocols don't have a PCB with userid, so PF can't restrict in those cases) but avoids some cases, and in particular makes it more obvious when a port does things like download extra distfiles or dependencies as part of the build process.
