+Subject: [PATCH] Fix segfault in login
+
+Fix a bug in readfileat where *plen would be corrupted if you didn't supply
+your own buffer (because ibuf is 0 in that case, not a pointer to the start
+of the allocated space). This caused a segfault in the 'login' program.
+
+Partial backport of upstream commit 81f31e463bd982a8344ea8681938eb43c9114652
