r3545: initial support for using extended attributes to hold extended dos attributes of files. I decided to use IDL/NDR to encode the attribute, as it gives us a simple way to describe and extend the saved attributes. The xattr code needs to hook into quite a few more places in the pvfs code, but this at least gets the basics done. I will start encoding alternate data streams streams, DOS EAs etc soon using the same basic mechanism. I'll probably stick to "version 1" for the xattr.idl for quite a while even though it will be changing, as I don't expect anyone to be deploying this in production just yet. Once we have production users we will need to keep compatibility by supporting all the old version numbers in xattr.idl. (This used to be commit c54253ed1b7dce1d14f43e747da61089aea87094)

r5102: This is a major simplification of the logic for controlling top level servers in smbd. The old code still contained a fairly bit of legacy from the time when smbd was only handling SMB connection. The new code gets rid of all of the smb_server specific code in smbd/, and creates a much simpler infrastructures for new server code. Major changes include: - simplified the process model code a lot. - got rid of the top level server and service structures completely. The top level context is now the event_context. This got rid of service.h and server.h completely (they were the most confusing parts of the old code) - added service_stream.[ch] for the helper functions that are specific to stream type services (services that handle streams, and use a logically separate process per connection) - got rid of the builtin idle_handler code in the service logic, as none of the servers were using it, and it can easily be handled by a server in future by adding its own timed_event to the event context. - fixed some major memory leaks in the rpc server code. - added registration of servers, rather than hard coding our list of possible servers. This allows for servers as modules in the future. - temporarily disabled the winbind code until I add the helper functions for that type of server - added error checking on service startup. If a configured server fails to startup then smbd doesn't startup. - cleaned up the command line handling in smbd, removing unused options (This used to be commit cf6a46c3cbde7b1eb1b86bd3882b953a2de3a42e)

r4242: added support for storing xattrs in a tdb. This allows all advanced NT attributes (streams, EAs, NT ACLs, timestamps etc) to be used on filesystems that don't support xattrs. It also allows for large streams, although they are very inefficient. I won't enable this by default, as I really wrote it as a way of testing large stream support while still using ext3, but perhaps with a bit more work this could be generally usable. To enable this use: posix:eadb = /home/test/myeas.tdb (This used to be commit 0c927d912cb65754351189d3a0442004a14aa5c6)

r2561: completely redid the ntvfs module chaining code, You can now do something like: ntvfs handler = nbench posix and the nbench pass-thru module will be called before the posix module. The chaining logic is now much saner, and less racy, with each level in the chain getting its own private pointer rather than relying on save/restore logic in the pass-thru module. The only pass-thru module we have at the moment is the nbench one (which records all traffic in a nbench compatibe format), but I plan on soon writing a "unixuid" pass-thru module that will implement the setegid()/setgroups()/seteuid() logic for standard posix uid handling. This separation of the posix backend from the uid handling should simplify the code, and make development easier. I also modified the nbench module so it can do multiple chaining, so if you want to you can do: ntvfs module = nbench nbench posix and it will save 2 copies of the log file in /tmp. This is really only useful for testing at the moment until we have more than one pass-thru module. (This used to be commit f84c0af35cb54c8fdc4933afefc18fa4c062aae4)

Major changes include: - simplified the process model code a lot. - got rid of the top level server and service structures completely. The top level context is now the event_context. This got rid of service.h and server.h completely (they were the most confusing parts of the old code) - added service_stream.[ch] for the helper functions that are specific to stream type services (services that handle streams, and use a logically separate process per connection) - got rid of the builtin idle_handler code in the service logic, as none of the servers were using it, and it can easily be handled by a server in future by adding its own timed_event to the event context. - fixed some major memory leaks in the rpc server code. - added registration of servers, rather than hard coding our list of possible servers. This allows for servers as modules in the future. - temporarily disabled the winbind code until I add the helper functions for that type of server - added error checking on service startup. If a configured server fails to startup then smbd doesn't startup. - cleaned up the command line handling in smbd, removing unused options (This used to be commit cf6a46c3cbde7b1eb1b86bd3882b953a2de3a42e)

r3029: implemented byte range lock timeouts. This adds a pvfs_wait_message() routine which uses the new messaging system, event timers and talloc destructors to give a nice generic async event handling system with a easy to use interface. The extensions to pvfs_lock.c are based on calls to pvfs_wait_message() routines. We now pass all of our smbtorture locking tests, although while writing this code I have thought of some additonal tests that should be added, particularly for lock cancel operations. I'll work on that soon. This commit also extends the smbtorture lock tests to test the rather weird 0xEEFFFFFF locking semantics that I have discovered in win2003. Win2003 treats the 0xEEFFFFFF boundary as special, and will give different error codes on either side of it. Locks on both sides are allowed, the only difference is which error code is given when a lock is denied. Anyone like to hazard a guess as to why? It has me stumped.

The code is taken from lib/idr.c in the 2.6 Linux kernel, and is very fast and space efficient. By using talloc it even has auto cleanup. This commit converts the handling of open file handles and open directory search handles to use the idtree routines. In combination with talloc destructors, this simplifies the structure handling in the pvfs backend a lot. For example, we no longer need to keep a linked list of open directory searches at all, and we no longer need to do linear scans of the list of open files on most operations. The end result is that the pvfs code is now extremely scalable. You can have 10s of thousands of open files and open searches and the code still runs very fast. I have also added a small optimisation into the file close path, to avoid looking in the byte range locking database if we know that there are no locks outstanding.

r2660: - converted the libcli/raw/ library to use talloc_increase_ref_count() rather than manual reference counts - properly support SMBexit in the cifs and posix backends - added a logoff method to all backends With these changes the RAW-CONTEXT test now passes against the posix backend (This used to be commit c315d6ac1cc40546fde1474702a6d66d07ee13c8)

r3039: This solves the problem of async handlers in ntvfs backends not being in the right state when called. For example, when we use the unixuid handler in the chain of handlers, and a backend decides to continue a call asynchronously then we need to ensure that the continuation happens with the right security context. The solution is to add a new ntvfs operation ntvfs_async_setup(), which calls all the way down through the layers, setting up anything that is required, and takes a private pointer. The backend wanting to make a async calls can use ntvfs_async_setup() to ensure that the modules above it are called when doing async processing.
