* Revert "[CIFS] Fix ntlmv2 auth with ntlmssp"Steve French2010-09-08
| | | | | | | | | | | | This reverts commit 9fbc590860e75785bdaf8b83e48fabfe4d4f7d58. The change to kernel crypto and fixes to ntlvm2 and ntlmssp series, introduced a regression. Deferring this patch series to 2.6.37 after Shirish fixes it. Signed-off-by: Steve French <sfrench@us.ibm.com> Acked-by: Jeff Layton <jlayton@redhat.com> CC: Shirish Pargaonkar <shirishp@us.ibm.com>
* [CIFS] Fix ntlmv2 auth with ntlmsspSteve French2010-08-20
| | | | | | | | | | | | | | | | | | | | | Make ntlmv2 as an authentication mechanism within ntlmssp instead of ntlmv1. Parse type 2 response in ntlmssp negotiation to pluck AV pairs and use them to calculate ntlmv2 response token. Also, assign domain name from the sever response in type 2 packet of ntlmssp and use that (netbios) domain name in calculation of response. Enable cifs/smb signing using rc4 and md5. Changed name of the structure mac_key to session_key to reflect the type of key it holds. Use kernel crypto_shash_* APIs instead of the equivalent cifs functions.

* [CIFS] cleanup asn handling for ntlmsspSteve French2009-06-24
| | | | | | | | | | | Also removes obsolete distinction between rawntlmssp and ntlmssp (in asn/SPNEGO) since as jra noted we can always send raw ntlmssp in session setup now. remove check for experimental runtime flag (/proc/fs/cifs/Experimental) in ntlmssp path.

* [CIFS] distinguish between Kerberos and MSKerberos in upcallSteve French2008-08-19
| | | | | | | | | | | | Properly handle MSKRB5 by passing sec=mskrb5 to the upcall so that the spengo blob can be generated appropriately. Also, make decode_negTokenInit prefer whichever mechanism is first in the list. Needed for some NetApp servers, and possibly some older versions of Windows which treat the two KRB5 mechanisms differently.

* [CIFS] remove level of indentation from decode_negTokenInitJeff Layton2008-07-31
| | | | | | | | | Most of this function takes place inside of an unnecessary "else" clause. The other 2 cases both return 0, so we can remove some indentation here. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>
* [CIFS] oid should also be checked against class in cifs asnSteve French2008-07-29
| | | | | | | | The oid coming back from asn1_header_decode is a primitive object so class should be checked to be universal. Acked-by: Love Hörnquist Åstrand <lha@kth.se> Signed-off-by: Steve French <sfrench@us.ibm.com>
* When verifying the decoded header before decoding the object identifierChris Wright2008-07-24
| | | | | | | | | | | (expecting a SPNEGO pseudo-mechanism oid), the test to verify it is a primitive encoding is compared against the asn1 class. Primitive is not a class. This brings check in line with similar check for krb/ntlmssp oid.

* asn1: additional sanity checking during BER decodingChris Wright2008-06-05
| | | | | | | | | | | | | | | | | | | - Don't trust a length which is greater than the working buffer. An invalid length could cause overflow when calculating buffer size for decoding oid. - An oid length of zero is invalid and allows for an off-by-one error when decoding oid because the first subid actually encodes first 2 subids. - A primitive encoding may not have an indefinite length.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
