KEYS: Merge the type-specific data with the payload data

2015-10-21T14:18:36+00:00

Merge the type-specific data with the payload data into one four-word chunk
as it seems pointless to keep them separate.

Use user_key_payload() for accessing the payloads of overloaded
user-defined keys.

Set UID in sess_auth_rawntlmssp_authenticate too

2014-12-08T05:43:02+00:00

A user complained that they were unable to login to their cifs share
after a kernel update. From the wiretrace we can see that the server
returns different UIDs as response to NTLMSSP_NEGOTIATE and NTLMSSP_AUTH
phases.

With changes in the authentication code, we no longer set the
cifs_sess->Suid returned in response to the NTLM_AUTH phase and continue
to use the UID sent in response to the NTLMSSP_NEGOTIATE phase. This
results in the server denying access to the user when the user attempts
to do a tcon connect.

See https://bugzilla.redhat.com/show_bug.cgi?id=1163927

A test kernel containing patch was tested successfully by the user.

cifs: remove dead code

2014-09-16T10:30:11+00:00

cifs provides two dummy functions 'sess_auth_lanman' and
'sess_auth_kerberos' for the case in which the respective
features are not defined. However, the caller is also under
an #ifdef, so we just get warnings about unused code:

fs/cifs/sess.c:1109:1: warning: 'sess_auth_kerberos' defined but not used [-Wunused-function]
 sess_auth_kerberos(struct sess_data *sess_data)

Removing the dead functions gets rid of the warnings without
any downsides that I can see.

(Yalin Wang reported the identical problem and fix so added him)

cifs: Separate rawntlmssp auth from CIFS_SessSetup()

2014-08-01T04:11:15+00:00

Separate rawntlmssp authentication from CIFS_SessSetup(). Also cleanup
CIFS_SessSetup() since we no longer do any auth within it.
