Daniel Drake 894ec8707c [PATCH] Fix listxattr() for generic security attributes 
Commit f549d6c18c introduced a generic
fallback for security xattrs, but appears to include a subtle bug.

Gentoo users with kernels with selinux compiled in, and coreutils compiled
with acl support, noticed that they could not copy files on tmpfs using
'cp'.

cp (compiled with acl support) copies the file, lists the extended
attributes on the old file, copies them all to the new file, and then
exits.  However the listxattr() calls were failing with this odd behaviour:

llistxattr("a.out", (nil), 0)           = 17
llistxattr("a.out", 0x7fffff8c6cb0, 17) = -1 ERANGE (Numerical result out of
range)

I believe this is a simple problem in the logic used to check the buffer
sizes; if the user sends a buffer the exact size of the data, then its ok
:)

This change solves the problem.
