From 29f621af8d39d5a140da584ff6c1eb00147b5a56 Mon Sep 17 00:00:00 2001

Subject: [PATCH] libfuse: null-terminate buffer in fuse_req_getgroups()
After reading the file /proc/$PID/task/$PID/status the buffer wasn't
terminated with a null character. This could theoretically lead to buffer
overrun by the subsequent strstr() call.
Since the contents of the proc file are guaranteed to contain the pattern
that strstr is looking for, this doesn't happen in normal situations.
Add null termination for robustness.
