e959bdcca4 The format of data we are sending over the network will be flexible when 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.

dcff7d3672 Create structs carrying the data of individual VFS functions, and hand those 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. 2010-03-16 09:52:08 -04:00

2a643ef10c Introduce smb_traffic_analyzer protocol v2. 
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.

8303bc49a4 Restructure the connect function code to always call 
down to NEXT-> before initializing. This allows us to
do cleanup (by calling DISCONNECT) if initialization
fails. Also fix vfs_acl_xattr which was failing to
call the NEXT connect function.

cde1b09d68 Fixed build warning "passing arg from incompatible pointer type" 
The fix explicitly makes the conversion from timeval to time_t using the
existing time utility functions.

370cbe0060 Turn the socket connections into a refcounted list - in the common case there'll now only be one socket per smbd. 
Changed the format of the wire data to (a) include a version number (V1) as the first element. (b) removed the
";)" at the end an replaced it with a "\n". Receiver can change back if needed, and now receiver can just log
"as-is" to a text file (making testing easier). Added my (C). Sorry Holger, but I've changed quite a bit now.

c164ff2be5 Convert to allocated strings. Use write_data(), not send as this doesn't correctly 
deal with EINTR. Jim and Holger please check this still works.

321191d5e2 Restructure the module so it connects to the remote data sink 
on connect, and closes the socket on client disconnect. This should
make it much more efficient. Store the remote fd in a private data
pointer off the handle. Finally we need to remove the fstrings and
convert to allocated buffer storage.

da6c7aa2a1 Use IPv4/v6 independent calls. Change safe_strcpy/cat to strlcpy/cat (this 
needs changing to talloc_sprintf) and fix file descriptor resource leaks
in error paths. Jim and Holger please check !

964fb9f249 SMB traffic analyzer vfs module from Holger Hetterich <hhetter@novell.com> 
Used to gather data to feed to a database for live and historical
analysis of usage per user, per share, etc.

Helper apps to read the data still to come.  This one still needs to be
made ipv6 enabled (connection is made to the helper app).
