* NTLM auth and sign - Define crypto hash functions and create and send keys ↵Shirish Pargaonkar2010-10-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | needed for key exchange Mark dependency on crypto modules in Kconfig. Defining per structures sdesc and cifs_secmech which are used to store crypto hash functions and contexts. They are stored per smb connection and used for all auth mechs to genereate hash values and signatures. Allocate crypto hashing functions, security descriptiors, and respective contexts when a smb/tcp connection is established. Release them when a tcp/smb connection is taken down. md5 and hmac-md5 are two crypto hashing functions that are used throught the life of an smb/tcp connection by various functions that calcualte signagure and ntlmv2 hash, HMAC etc. structure ntlmssp_auth is defined as per smb connection. ntlmssp_auth holds ciphertext which is genereated by rc4/arc4 encryption of secondary key, a nonce using ntlmv2 session key and sent in the session key field of the type 3 message sent by the client during ntlmssp negotiation/exchange A key is exchanged with the server if client indicates so in flags in type 1 messsage and server agrees in flag in type 2 message of ntlmssp negotiation. If both client and agree, a key sent by client in type 3 message of ntlmssp negotiation in the session key field. The key is a ciphertext generated off of secondary key, a nonce, using ntlmv2 hash via rc4/arc4. Signing works for ntlmssp in this patch. The sequence number within the server structure needs to be zero until session is established i.e. till type 3 packet of ntlmssp exchange of a to be very first smb session on that smb connection is sent.

* cifs: cifs_convert_address() returns zero on errorDan Carpenter2010-10-26
| | | | | | | | | | | The cifs_convert_address() returns zero on error but this caller is testing for negative returns. Btw. "i" is unsigned here, so it's never negative.

* NTLM auth and sign - Allocate session key/client response dynamicallyShirish Pargaonkar2010-10-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Start calculating auth response within a session. Move/Add pertinet data structures like session key, server challenge and ntlmv2_hash in a session structure. We should do the calculations within a session before copying session key and response over to server data structures because a session setup can fail. Only after a very first smb session succeeds, it copy/make its session key, session key of smb connection. This key stays with the smb connection throughout its life. sequence_number within server is set to 0x2. The authentication Message Authentication Key (mak) which consists of session key followed by client response within structure session_key is now dynamic. Every authentication type allocates the key + response sized memory within its session structure and later either assigns or frees it once the client response is sent and if session's session key becomes connetion's session key. ntlm/ntlmi authentication functions are rearranged. A function named setup_ntlm_resp(), similar to setup_ntlmv2_resp(), replaces function cifs_calculate_session_key(). size of CIFS_SESS_KEY_SIZE is changed to 16, to reflect the byte size of the key it holds.

* cifs: eliminate cifsInodeInfo->write_behind_rc (try #6)Jeff Layton2010-10-24
| | | | | | | | | | | | | | | write_behind_rc is redundant and just adds complexity to the code. What we really want to do instead is to use mapping_set_error to reset the flags on the mapping when we find a writeback error and can't report it to userspace yet. For cifs_flush and cifs_fsync, we shouldn't reset the flags since errors returned there do get reported to userspace.

| | | | | | | | | | | | | | | The f_op->flush operation is the last chance to return a writeback related error when closing a file. Ensure that we don't miss reporting any errors by waiting for writeback to complete in cifs_flush before proceeding. There's no reason to do this when the file isn't open for write however.

| | | | | | | | | | | The count for cifsFileInfo is currently an atomic, but that just adds complexity for little value. We generally need to hold cifs_file_list_lock to traverse the lists anyway so we might as well make this counter non-atomic and simply use the cifs_file_list_lock to protect it.
