* s3: vfs_smb_traffic_analyzer.c: add VFS functions for file open and closeHolger Hetterich2010-03-162-2/+65
|
* smb_traffic_analyzer.c: optimize marshalling function and documentHolger Hetterich2010-03-162-34/+54
| | | | | | | | | Collect all data that is needed, and use only one talloc_asprintf operation to create the string of common data. This simplifies the code a bit and is most probably faster than the old method. Also, #define SMBTA_COMMON_DATA_COUNT as a complete string, speeding things up because we know the value at compile time.
* vfs_smb_traffic_analyzer.c: added functionHolger Hetterich2010-03-161-63/+58
| | | | | | | | | static char *smb_traffic_analyzer_anonymize This takes a lot of code out of the main functions, and makes it a bit simpler. Do the anonymization in a function. Since we already anonymized the username we don't need to do this a second time in the v2 marshalling function.
* Simplify the code a bit by creating the functions:Holger Hetterich2010-03-161-84/+123
| | | | | | | smb_traffic_analyzer_encrypt - doing the encryption of a data block, smb_traffic_analyzer_create_header - create the protocol header, smb_traffic_analyzer_write_data - actually write the data to the socket.
* Add the number of common data blocks to the protocol.Holger Hetterich2010-03-162-10/+33
| | | | | | | | | | | Always send the number of common data blocks first. This way, we can make the protocol backwards compatible. A receiver running with an older subprotocol can just ignore if a newer sender sends more common data. Add a few remarks to the marshalling function. Add two #define lines defining the protocol subrelease number and the number of common data blocks to the header file.
* Put all the protocol stuff into a separate header file.Holger Hetterich2010-03-162-114/+152
| | | | | | All the structures and the vfs function identifier list is required by the receiver. It's therefore very handy to have this in an extra header file.
* Add smbta-util to manage the encryption key.Holger Hetterich2010-03-163-4/+225
| | | | | | | This program allows the administrator to enable or disable AES encryption when using vfs_smb_traffic_analyzer. It also generates new keys, stores them to a file, so that the file can be reused on another client or server.
* Implement AES encryption of the data block.Holger Hetterich2010-03-161-13/+33
| | | | | | | | | | | | First try. This runs on 16 bytes long AES block size, and enlarges the data block with 16 bytes, to make sure all bytes are in. The added bytes are filled with '.'. It then creates a header featuring the new length to be send, and finally sends the data block, then returns. This code is untested, as creating the receiver will be my next step. To simplify traffic_analyzer's code, this code should run as a function. It's on the do-to-list.
* Implement anonymization for protocol v2.Holger Hetterich2010-03-161-14/+53
| | | | | | | | | Since we need to care for the SID too, do the anonymization in the marshalling function and anonymize both the username and the SID. Remove the 'A' status flag from the header definition. A listener could see from the unencrypted header if the module is anonymizing or not, which is certainly not wanted.
* Make all remarks compatible to the linux kernel coding styleguide.Holger Hetterich2010-03-161-27/+33

* Added an exact description of the V2 protocol.Holger Hetterich2010-03-161-0/+62
| | | | | I don't think it should have it's place the man page, because this is developer information.
* Move the creation of the header.Holger Hetterich2010-03-161-11/+37
| | | | | | | | | | | | | | | | | | | | Since the header block of the protocol contains the number of bytes to come, we always send the header itself unmodified. If we compress or crypt the data we are about to send, the length of the data to send may change. Therefore, we no longer create the header in smb_traffic_analyzer_create_string, but shortly before we send the data. For both cases, encryption and normal, we create our own header, and send it before the actual data. In case of protocol v1, we don't need to create an extra header. Just send the data, and return from the function. Change a debug message to say that the header for crypted data has been created. Add a status flags consisting of 6 bytes to the header. Their function will be descriped in one of the next patches, which is descriping the header in a longer comment. When anonymization and/or encryption is used, set the flags accordingly.

* The format of data we are sending over the network will be flexible when ↵Holger Hetterich2010-03-161-4/+74
| | | | | | | sending over the network in protocol v2. To be able to do this, we create a new va-list function that is creating the buffer to send. Also it makes it easier for the receiver to parse the data; it sends an initial header containing the full length of the buffer to be send. For the individual strings, it sends sub headers containing the length of the upcoming substring to be send. With the header-data-header-data [..] structure we don't need to quote the sub strings finally enabling having all possible character sets in filenames etc.. In the sending function, implement mkdir to actually send it's data for testing.
* Create structs carrying the data of individual VFS functions, and hand those ↵Holger Hetterich2010-03-161-33/+47
| | | | over to the send function, which then casts the void pointer to the struct required by looking at the id. This allows us to return different result data depending on the VFS function that is running. Make the protocol v1 sender compatible to this. Adapt the existing VFS functions to use the new data structures. Make use of the new functionality and extend the mkdir VFS logger function to return the creation mode additionally.
* Introduce smb_traffic_analyzer protocol v2.Holger Hetterich2010-03-161-7/+62
| | | | | | | From Holger: Make smb_traffic_analyzer differ the protocol versions to enable the development of version 2 of the protocol. To do this, a new parameter "protocol_version" has been introduced, which can be set to "V1", "V2", or nothing. If protocol_version is not set, V1 will be chosen automatically. Created an enum for identifying VFS functions in the upcoming protocol v2. Converted the existing VFS functions to use the identifier, and set the read/write bool used in protocol v1 accordingly, also ignore any other VFS functions except read/write/pread/pwrite in v1. Added a first new VFS function for mkdir, which I use for testing and implementing both the sender and receiver for v2.

| | | | | | | | | | | | | Use accessor functions to get to this value. Tidies up much of the user context code. Volker, please look at the changes in smbd/uid.c to familiarize yourself with these changes as I think they make the logic in there cleaner. Cause smbd/posix_acls.c code to look at current user context, not stored context on the conn struct - allows correct use of these function calls under a become_root()/unbecome_root() pair. Jeremy.
