+Subject: gssd: replace non-thread-safe strtok with strsep
+
+gssd uses the non-thread-safe strtok() function, which
+can lead to incorrect program behavior.
+
+Replace strtok() with the thread-safe strsep().

+Subject: gssd: Duplicate the upcall string for error messages
+
+strsep() modifies the input string, so error messages
+may output only part of the upcall string.
+
+Make a copy of the upcall string, and use that in any
+error messages.
