+
+    gssd: fix crash in debug message.
+    
+    A recent cleanup of debug messages added func and tid format specifiers
+    to a debug message (when full hostname was different), but the func name
+    and tid were NOT added as arguments.
+    
+    Consequently there weren't enough args, random bytes of the stack were
+    interpreted as a pointer, and rpc.gssd crashed (when -v was specified).
+    
+    Fixes: b538862a5135 ("gssd: Cleaned up debug messages")

+Author: Steve Dickson <steved@redhat.com>

+
+    mount.nfs: Fix the sloppy option processing
+    
+    The new mount API broke how the sloppy option is parsed.
+    So the option processing needs to be moved up in
+    the mount.nfs command.
+    
+    The option needs to be the first option in the string
+    that is passed into the kernel with the -s mount(8)
+    and/or the -o sloppy is used.
+    
+    Commit 92b664ef fixed the process of the -s flag
+    and this version fixes the -o sloppy processing
+    as well works when libmount-mount is and is not
+    enabled plus cleans up the mount options passed
+    to the kernel.
