[tor-commits] [tor/master] ExitPolicyRejectPrivate rejects local IPv6 address and interface addresses



commit 098b82c7b2a6bb711e3616eb5b7e7e5e7401f01d
Author: teor (Tim Wilson-Brown) <teor2345@xxxxxxxxx>
Date:   Tue Sep 15 18:34:18 2015 +1000

    ExitPolicyRejectPrivate rejects local IPv6 address and interface addresses
    
    ExitPolicyRejectPrivate now rejects more local addresses by default:
     * the relay's published IPv6 address (if any), and
     * any publicly routable IPv4 or IPv6 addresses on any local interfaces.
    
    This resolves a security issue for IPv6 Exits and multihomed Exits that
    trust connections originating from localhost.
    
    Resolves ticket 17027. Patch by "teor".
    Patch on 42b8fb5a1523 (11 Nov 2007), released in 0.2.0.11-alpha.
