Hey All,

Many of you know that I've been working on Capsicum support in Tor.
I've added a ports entry for it in the HardenedBSD ports tree,

To enable capmode, you'll need to add "Sandbox 1" to your torrc. Note
that since libevent does not support Capsicum and creates sockets on
its own, using DNSPort (most commonly used in transparent proxy
setups) with capmode enabled is unsupported. I've filed a bug report
with libevent to start the discussion around adding a
Capsicum-friendly API for socket creation/maintenance.

On HardenedBSD 12-CURRENT/amd64, security/tor-capsicum is compiled with:
  - PIE
  - Full RELRO
  - CFI (without the cfi-icall scheme)
  - SafeStack
  - Retpoline
  - Capsicum support

Please test and let me know any success or failure stories.
