- AppArmor network rules must use socket types (stream/dgram),
not protocol names (tcp/udp/icmp): the parser rejected the
profile (Invalid network entry) until fixed.
- Tinyproxy has no 'Upstream none' syntax; the line failed the
service at startup. Direct connection is the default, so the
line is removed.
- Tinyproxy Filter is POSIX BASIC regex, not extended: the
extended-style anchored patterns denied even allowed domains
(verified: xcmapi.org got 403). Rewritten in basic syntax
(\(...\)* groups); the anchored form still blocks
evilgithub.com and xcmapi.org.evil.com (verified on host).
- Filter file must be world-readable (was 640 root:root, so
tinyproxy could not read it and exited on reload); install
steps now chmod 644 (documented in the filter header via
the install note in tinyproxy.conf).
Host already runs these exact files (proxy allow/block
verified: xcmapi/github/api.github 200, example/evilgithub/
xcmapi.org.evil.com 403).
