pull up r24639, r24641 from trunk

r24641 | ghudson | 2011-02-18 10:06:57 -0500 (Fri, 18 Feb 2011) | 7 lines

ticket: 6869

Fix a conceptual bug in r24639: the intermediate key container length
should be the hash's output size, not its block size. (The bug did
not show up in testing because it is harmless in practice; MD5 has a
larger block size than output size.)

subject: hmac-md5 checksum doesn't work with DES keys
target_version: 1.9
tags: pullup

krb5int_hmacmd5_checksum calculates an intermediate key using an HMAC.
The container for this key should be allocated using the HMAC output
size (which is the hash blocksize), not the original key size. This
bug was causing the function to fail with DES keys, which can be used
with hmac-md5 in PAC signatures.
