Subject: [PATCH] Fix writing ICEAuthority file
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Commit 9398f6cf8933055b31506ba155aef2fc2b3561d7 "Remove iceauth
dependency" introduced two bugs:

1) "fp" is never closed, so the generated auth data stays buffered in
   memory for some indeterminate time and the file stays empty on disk.
   This completely breaks authentication and thus also session restore.

2) Checking the return value of IceWriteAuthFileEntry() is inverted (the
   function returns non-zero on success), so warnings are printed iff
   everything goes well.

BUG: 487912

(cherry picked from commit 0dcf34458d99b07a3d9054ae0c86c656e0dfa7aa)
