New Revision: 310954
URL: https://svnweb.freebsd.org/changeset/base/310954
Log:
Set value->v.octetstring.len to a correct value on malloc success/failure
The previous code always set value->v.octetstring.len to len, regardless
of the result from the malloc call. This misleads the caller on malloc
failure. Set .len to len on success and 0 on failure.
