The patch titled
knfsd: nfsd4: fix non-terminated string
has been removed from the -mm tree. Its filename was
knfsd-nfsd4-fix-non-terminated-string.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: knfsd: nfsd4: fix non-terminated string
From: J. Bruce Fields <bfields@xxxxxxxxxxxxxx>
The server name is expected to be a null-terminated string, so we can't pass
in the raw client identifier.
What's more, the client identifier is just a binary, not necessarily
printable, blob. Let's just use the ip address instead. The server name
appears to exist just to help debugging by making some printk's more
informative.
Note that the string is copies into the rpc client structure, so the pointer
to the local variable does not outlive the function call.
