  Modified files:
    libexec/fingerd      fingerd.8 fingerd.c 
  Log:
  When the -p flag is specified, set an environment variable to the name
  of the remote host (or rather, the name as mangled by realhostname_sa())
  so that the process can use it to behave differently depending on the
  origin on the request.  We use this to implement rudimentary visibility
  control on our user information.
  
  Make sure that the child process's standard error goes through the same
  NVT-ASCII filter as is applied to the standard output.
  
  Don't attempt to call logerr() from the child since stdio is not safe in
  a vforked process.  Just write a message to fd 2 instead.  (Ideally, the
  parent would open two pipes, and siphon off our stderr to some place less
  public, but I have not attempted to do so in this implementation.)
