Linux-2.6.12-rc2 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!

cifs: change signing routines to deal with smb_rqst structs We need a way to represent a call to be sent on the wire that does not require having all of the page data kmapped. Behold the smb_rqst struct. This new struct represents an array of kvecs immediately followed by an array of pages. Convert the signing routines to use these structs under the hood and turn the existing functions for this into wrappers around that. For now, we're just changing these functions to take different args. Later, we'll teach them how to deal with arrays of pages.

cifs: turn smb_send into a wrapper around smb_sendv cifs: turn smb_send into a wrapper around smb_sendv Rename smb_send2 to smb_sendv to make it consistent with kernel naming conventions for functions that take a vector. There's no need to have 2 functions to handle sending SMB calls. Turn smb_send into a wrapper around smb_sendv. This also allows us to properly mark the socket as needing to be reconnected when there's a partial send from smb_send. Also, in practice we always use the address and noblocksnd flag that's attached to the TCP_Server_Info. There's no need to pass them in as separate args to smb_sendv.

It'll never call this code if that's the case. Finally do a little cleanup. Use "goto out" on errors so that the flow of code in the normal case is more evident.

There are eight callers (SMB worker functions) which are primarily affected by this change: TreeDisconnect, uLogoff, Close, findClose, SetFileSize, SetFileTimes, Lock and PosixLock CC: Dave Kleikamp <shaggy@austin.ibm.com> CC: Przemyslaw Wegrzyn <czajnik@czajsoft.pl> Acked-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

move sectype to the cifs_ses instead of TCP_Server_Info Now that we track what sort of NEGOTIATE response was received, stop mandating that every session on a socket use the same type of auth. Push that decision out into the session setup code, and make the sectype a per-session property. This should allow us to mix multiple sectypes on a socket as long as they are compatible with the NEGOTIATE response. With this too, we can now eliminate the ses->secFlg field since that info is redundant and harder to work with than a securityEnum.

[CIFS] Fix cifsacl mounts over smb2 to not call cifs When mounting with smb2/smb3 (e.g. vers=2.1) and cifsacl mount option, it was trying to get the mode by querying the acl over the cifs rather than smb2 protocol. This patch makes that protocol independent and makes cifsacl smb2 mounts return a more intuitive operation not supported error (until we add a worker function for smb2_get_acl). Note that a previous patch fixed getxattr/setxattr for the CIFSACL xattr which would unconditionally call cifs_get_acl and cifs_set_acl (even when mounted smb2). I made those protocol independent last week (new protocol version operations "get_acl" and "set_acl" but did not add an smb2_get_acl and smb2_set_acl yet so those now simply return EOPNOTSUPP which at least is better than sending cifs requests on smb2 mount) The previous patches did not fix the one remaining case though ie mounting with "cifsacl" when getting mode from acl would unconditionally end up calling "cifs_get_acl_from_fid" even for smb2 - so made that protocol independent but to make that protocol independent had to make sure that the callers were passing the protocol independent handle structure (cifs_fid) instead of cifs specific _u16 network file handle (ie cifs_fid instead of cifs_fid->fid) Now mount with smb2 and cifsacl mount options will return EOPNOTSUP (instead of timing out) and a future patch will add smb2 operations (e.g. get_smb2_acl) to enable this.

When either an Owner or a Group of a file object at the server is changed, rest of security descriptor remains same (DACL etc.). To set security descriptor, it is necessary to open that file with permission bits of either WRITE_DAC if DACL is being modified or WRITE_OWNER (Take Ownership) if Owner or Group is being changed.

cifs: add cifs_async_readv ...which will allow cifs to do an asynchronous read call to the server. The caller will allocate and set up cifs_readdata for each READ_AND_X call that should be issued on the wire. The pages passed in are added to the pagecache, but not placed on the LRU list yet (as we need the page->lru to keep the pages on the list in the readdata). When cifsd identifies the mid, it will see that there is a special receive handler for the call, and use that to receive the rest of the frame. cifs_readv_receive will then marshal up a kvec array with kmapped pages from the pagecache, which eliminates one copy of the data. Once the data is received, the pages are added to the LRU list, set uptodate, and unlocked.

cifs: track the enablement of signing in the TCP_Server_Info Currently, we determine this according to flags in the sec_mode, flags in the global_secflags and via other methods. That makes the semantics very hard to follow and there are corner cases where we don't handle this correctly. Add a new bool to the TCP_Server_Info that acts as a simple flag to tell us whether signing is enabled on this connection or not, and fix up the places that need to determine this to use that flag. This is a bit weird for the SMB2 case, where signing is per-session. SMB2 needs work in this area already though. The existing SMB2 code has similar logic to what we're using here, so there should be no real change in behavior. These changes should make it easier to implement per-session signing in the future though.

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.

Fortunately, it's easy to do - setting ->s_maxbytes can be done in cifs_read_super(), ditto for ->s_time_gran and as for putting MS_POSIXACL into ->s_flags, we can mirror it in ->mnt_cifs_flags until cifs_read_super() is called.

Allow setting per-file compression via CIFS protocol An earlier patch allowed setting the per-file compression flag "chattr +c filename" on an smb2 or smb3 mount, and also allowed lsattr to return whether a file on a cifs, or smb2/smb3 mount was compressed. This patch extends the ability to set the per-file compression flag to the cifs protocol, which uses a somewhat different IOCTL mechanism than SMB2, although the payload (the flags stored in the compression_state) are the same.

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.

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: Assume passwords are encoded according to iocharset (try #2) Re-posting a patch originally posted by Oskar Liljeblad after rebasing on 3.2. Modify cifs to assume that the supplied password is encoded according to iocharset. Before this patch passwords would be treated as raw 8-bit data, which made authentication with Unicode passwords impossible (at least passwords with characters > 0xFF). The previous code would as a side effect accept passwords encoded with ISO 8859-1, since Unicode < 0x100 basically is ISO 8859-1. Software which relies on that will no longer support password chars > 0x7F unless it also uses iocharset=iso8859-1. (mount.cifs does not care about the encoding so it will work as expected.)

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.

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: clean up handling when server doesn't consistently support inode numbers It's possible that a server will return a valid FileID when we query the FILE_INTERNAL_INFO for the root inode, but then zeroed out inode numbers when we do a FindFile with an infolevel of SMB_FIND_FILE_ID_FULL_DIR_INFO. In this situation turn off querying for server inode numbers, generate a warning for the user and just generate an inode number using iunique. Once we generate any inode number with iunique we can no longer use any server inode numbers or we risk collisions, so ensure that we don't do that in cifs_get_inode_info either.

A lookup for the tcon is already made in the calling functions and this way we avoid having to re-run the lookup.

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!
