2007-10-10r24284: change brlock_tdb.c to use the dbwrap API. This actually makes theAndrew Tridgell1-5/+1
backend abstraction for brlock pointless, but I have left it in place for now. It would be useful for other clustering systems that can't map to dbwrap, and would also be useful if we wanted to keep the remote function call capabilities in ctdb instead of the less efficient fetch_locked() call in dbwrap (This used to be commit 912c014b7c131ab051ff6eb2db4e68cb6fbbeb14)

2007-10-10r15734: This is a major change to the NTVFS subsystem:Stefan Metzmacher1-11/+11
- to use a struct ntvfs_handle instead of a uint16_t fnum. (to make it independend from the frontend protocol) - the allocation of handles now is provided by the frontend (smbsrv_*) via callbacks and not by each backend module - this also makes sure that file handles are only passed to the ntvfs subsystem when the tcon and session matches, so modules can rely on this and need to check this. - this allows multiple modules in the ntvfs module chain to allocate file handles. This can be used for virtual files like "\\$Extend\\$Quota:$Q:$INDEX_ALLOCATION"... - also this will make SMB2 with 128 bit file handles possible metze (This used to be commit 287fc1c22d670f6e568014b420f7f4cb31dc7958)

2007-10-10r7294: implemented the irpc messaging system. This is the core of theAndrew Tridgell1-0/+1
management system I proposed on samba-technical a couple of days ago. Essentially it is a very lightweight way for any code in Samba to make IDL based rpc calls to anywhere else in the code, without the client or server having to go to the trouble of setting up a full rpc service. It can be used with any of our existing IDL, but I expect it will mostly be used for a new set of Samba specific management calls. The LOCAL-IRPC torture test demonstrates how it can be used by calling the echo_AddOne() call over this transport. (This used to be commit 3d589a09954eb8b318f567e1150b0c27412fb942)

2007-10-10r5298: - got rid of pstring.h from includes.h. This at least makes it a bitAndrew Tridgell1-0/+1
less likely that anyone will use pstring for new code - got rid of winbind_client.h from includes.h. This one triggered a huge change, as winbind_client.h was including system/filesys.h and defining the old uint32 and uint16 types, as well as its own pstring and fstring. (This used to be commit 9db6c79e902ec538108d6b7d3324039aabe1704f)
2007-10-10r5296: - only include the tdb headers where they are neededAndrew Tridgell1-0/+1
- removed the u32 hack in events.c as I think this was only needed as tdb.h defines u32. Metze, can you check that this hack is indeed no longer needed on your suse system? (This used to be commit 6f79432fe656164d4770dbce114a30dda5e7bf9a)

2007-10-10r5102: This is a major simplification of the logic for controlling top levelAndrew Tridgell1-3/+3
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)
2007-10-10r5037: got rid of all of the TALLOC_DEPRECATED stuff. My apologies for theAndrew Tridgell1-1/+1

2007-10-10r3528: added support for the SMBntcancel() operation, which cancels anyAndrew Tridgell1-7/+8
outstanding async operation (triggering an immediate timeout). pvfs now passes the RAW-MUX test (This used to be commit 3423e2f41461d054067ef168b9b986f62cc8f77c)
2007-10-10r3507: - added deferred replies on sharing violation in pvfs open. TheAndrew Tridgell1-5/+2
deferred reply is short-circuited immediately when the file is closed by another user, allowing it to be opened by the waiting user. - added a sane set of timeval manipulation routines - converted all the events code and code that uses it to use struct timeval instead of time_t, which allows for microsecond resolution instead of 1 second resolution. This was needed for doing the pvfs deferred open code, and is why the patch is so big. (This used to be commit 0d51511d408d91eb5f68a35e980e0875299b1831)
2007-10-10r3463: separated out some more headers (asn_1.h, messages.h, dlinklist.h and ↵Andrew Tridgell1-0/+1

2007-10-10r3360: improved the deletion of tmp files. smbd now puts all tmp files in ↵Andrew Tridgell1-3/+2
var/locks/smbd.tmp/ and deletes that dir on startup. (This used to be commit 7e942e7f1bd2c293a0e6648df43a96f8b8a2a295)
2007-10-10r3357: removed the need to use TDB_CLEAR_IF_FIRST in Samba4.Andrew Tridgell1-1/+1
We found a few months ago that TDB_CLEAR_IF_FIRST is extremely inefficient for large numbers of connections, due to a fundamental limitation in the way posix byte range locking is implemented. Rather than the nasty workaround we had for Samba3, we now have a single "cleanup tmp files" function that runs when smbd starts. That deletes the tmp tdbs, so TDB_CLEAR_IF_FIRST is not needed at all. (This used to be commit ffa285bc783c775a2d53a58fb691ca339e6c76ae)
2007-10-10r3312: in the brlock code, we prevent lock stampedes by attempting to notAndrew Tridgell1-1/+3
wakeup all pending locks at once. This change means that we only trigger this anti-stampede code for write locks, as for pending read locks the correct behaviour is to stampede (as they will all succeed) (This used to be commit 8021d1d74207db1204139309592b9d2f80f2bd0e)
2007-10-10r3271: use "struct messaging_context *" instead of "void *" in messaging APIAndrew Tridgell1-2/+2

2007-10-10r3126: in the brlock code I had used a void* for the brl context as I didn'tAndrew Tridgell1-14/+9
want to expose the brl context structure outside the brlock.c code. Instead, I now use "struct brl_context *" and rely on C being happy to pass around pointers to unknown structures as long as they are not dereferenced. I will be interested to see how the build farm likes this. (This used to be commit cb155c8ad837285c5a7f5b104968239df0b65fd2)
2007-10-10r3031: added support for lock cancelation, which effectively just triggers ↵Andrew Tridgell1-5/+14
an early lock timeout added support for more of the bizarre special lock offset semantics of w2k3 (This used to be commit d5bfc910b1200fb283e26572dc57fcf93652fd32)
2007-10-10r3029: implemented byte range lock timeouts.Andrew Tridgell1-28/+244
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. (This used to be commit 4395c0557ab175d6a8dd99df03c266325949ffa5)
2007-10-10r3012: added initial support for byte range locking in the posix vfs. This isAndrew Tridgell1-0/+418
enough for us to pass locktest, but does not yet support lock timeouts and some of the other esoteric features. (This used to be commit 58a92abd88f190bc60894a68e0528e95ae33fe39)
