  o Minor bugfixes:
    - Always NUL-terminate the sun_path field of a sockaddr_un before
      passing it to the kernel. (Not a security issue: kernels are
      smart enough to reject bad sockaddr_uns.) Found by Coverity; CID
      # 428. Bugfix on Tor 0.2.0.3-alpha.
Use strlcpy in create_unix_sockaddr() Using strncpy meant that if listenaddress were ever >= sizeof(sockaddr_un.sun_path), we would fail to nul-terminate sun_path. This isn't a big deal: we never read sun_path, and the kernel is smart enough to reject the sockaddr_un if it isn't nul-terminated. Nonetheless, it's a dumb failure mode. Instead, we should reject addresses that don't fit in sockaddr_un.sun_path. Coverity found this; it's CID 428. Bugfix on 0.2.0.3-alpha. 2011-07-01 18:06:54 +02:00			`o Minor bugfixes:`
