2007-10-10r17930: Merge noinclude branch:Jelmer Vernooij1-1/+1
* Move dlinklist.h, smb.h to subsystem-specific directories * Clean up ads.h and move what is left of it to dsdb/ (only place where it's used) (This used to be commit f7afa1cb77f3cfa7020b57de12e6003db7cfcc42)
2007-10-10r15734: This is a major change to the NTVFS subsystem:Stefan Metzmacher1-2/+2
- 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)
2007-10-10r15614: the byte range locking error handling caches the last failed lockStefan Metzmacher1-18/+15

(both are '1') metze (This used to be commit de9d04abcceae7b1e21f521d0bb2fa5129c237b2)
2007-10-10r14256: - rename smb_file -> smb_handleStefan Metzmacher1-2/+2
- move it into the in/out substructs again - allow file.path only on smb_fileinfo/smb_setfileinfo metze (This used to be commit be6d5298a2cdb7e7c61d70471bad445645af5963)
2007-10-10r14173: change smb interface structures to always useStefan Metzmacher1-2/+2
a union smb_file, to abtract - const char *path fot qpathinfo and setpathinfo - uint16_t fnum for SMB - smb2_handle handle for SMB2 the idea is to later add a struct ntvfs_handle *ntvfs so that the ntvfs subsystem don't need to know the difference between SMB and SMB2 metze (This used to be commit 2ef3f5970901b5accdb50f0d0115b5d46b0c788f)
2007-10-10r14157: - pass a struct ntvfs_request to the ntvfs layerStefan Metzmacher1-6/+6
(for now we just do #define ntvfs_request smbsrv_request, but it's the first step...) - rename ntvfs_openfile() -> ntvfs_open() - fix the talloc hierachie in some places in the ntvfs_map_*() code metze (This used to be commit ed9ed1f48f602354810937c0b0de850b44322191)

2007-10-10r8120: added in the newly found DOS locking error codes into the pvfs backendAndrew Tridgell1-2/+2
(This used to be commit d77b3820d16f60fb9119ac6eb70007363990b20d)
2007-10-10r7459: fixed pvfs for the RAW-MUX testAndrew Tridgell1-1/+1
when you cancel a lock, w2k3 gives NT_STATUS_FILE_LOCK_CONFLICT not NT_STATUS_CANCELLED. Strange. (This used to be commit a4f17fcd9218f16b6cc166b2f797e8889d6f63f4)
2007-10-10r6579: improved the handling of lock timeouts and cancels in the pvfs lockingAndrew Tridgell1-16/+16
code. On lock cancel don't retry the lock. (This used to be commit dffeb3c3d44d1b837a6036c47eb809ce1bd53b22)
2007-10-10r5037: got rid of all of the TALLOC_DEPRECATED stuff. My apologies for theAndrew Tridgell1-1/+1
large commit. I thought this was worthwhile to get done for consistency. (This used to be commit ec32b22ed5ec224f6324f5e069d15e92e38e15c0)
2007-10-10r3798: added support for alternate data streams in xattrs into pvfs.Andrew Tridgell1-9/+9
The trickiest part about this was getting the sharing and locking rules right, as alternate streams are separate locking spaces from the main file for the purposes of byte range locking, and separate for most share violation rules. I suspect there are still problems with delete on close with alternate data streams. I'll look at that next. (This used to be commit b6452c4a2068cf7e837778559da002ae191b508a)
2007-10-10r3658: use handle->fd == -1 as the primary indicator of a directory. ThisAndrew Tridgell1-1/+1
fixes a directory creation problem from WinXP (This used to be commit 4b3afc6c395b430e7e56d8ebe0ddf85c556a5df5)

2007-10-10r3615: split out struct pvfs_file_handle from struct pvfs_file. This is inAndrew Tridgell1-10/+11
preparation for adding code to pass the BASE-DENY1 and BASE-DENYDOS tests, which require a shared filesystem handle for some specific combinations of two DENY_DOS opens on the same connection. (This used to be commit 6e4fdf01d19051e3923d7703dbf990fc1722b09a)
2007-10-10r3595: - fixed a talloc_free ordering problem on cleanup with pending requestsAndrew Tridgell1-1/+1
- added initial support for MODE_INFORMATION in setfileinfo (I have no idea what "mode information" on a file is - it takes a value of 0, 2, 4 or 6. What could it be?) (This used to be commit e53ec2f6b68e1d19149c36ea8fcd25a204db38fb)
2007-10-10r3544: fixed some #include lines to make them more consistentAndrew Tridgell1-1/+1
(This used to be commit a1a0118bd3f1cae034a1c564d05c3aa8019ff932)
2007-10-10r3540: added testing of SMBntcancel in the open/open/close muxAndrew Tridgell1-1/+5
testing. Interestingly, w2k3 does not allow the cancel of an outstanding async open request, whereas it does allow the cancel of an outstanding async lock request. To support this I have changed the pvfs_wait interface to provide a enum on why the event is happening, so the callback can decide what to do. (This used to be commit f23d6a28008a13588cde24b5012ec21e488ac47a)
2007-10-10r3507: - added deferred replies on sharing violation in pvfs open. TheAndrew Tridgell1-3/+4
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/+2
ioctl.h) (This used to be commit b97e395c814762024336c1cf4d7c25be8da5813a)

2007-10-10r3336: use a struct ntvfs_async_state to be able to do async chaning of ↵Stefan Metzmacher1-7/+7
ntvfs modules the idea is that a passthru module can use ntvfs_async_state_push() before calling ntvfs_next_*() and in the _send function it calls ntvfs_async_state_pop() and then call the upper layer send_fn itself - ntvfs_nbench is now fully async - the ntvfs_map_*() functions and the trans(2) mapping functions are not converted yet metze (This used to be commit fde64c0dc142b53d128c8ba09af048dc58d8ef3a)
2007-10-10r3081: several updates to ntvfs and server side async request handling inAndrew Tridgell1-35/+8
preparation for the full share modes and ntcreatex code that I am working on. highlights include: - changed the way a backend determines if it is allowed to process a request asynchronously. The previous method of looking at the send_fn caused problems when an intermediate ntvfs module disabled it, and the caller then wanted to finished processing using this function. The new method is a REQ_CONTROL_MAY_ASYNC flag in req->control_flags, which is also a bit easier to read - fixed 2 bugs in the readbraw server code. One related to trying to answer a readbraw with smb signing (which can't work, and crashed our signing code), the second related to error handling, which attempted to send a normal SMB error packet, when readbraw must send a 0 read reply (as it has no header) - added several more ntvfs_generic.c generic mapping functions. This means that backends no longer need to implement such esoteric functions as SMBwriteunlock() if they don't want to. The backend can just request the mapping layer turn it into a write followed by an unlock. This makes the backends considerably simpler as they only need to implement one style of each function for lock, read, write, open etc, rather than the full host of functions that SMB provides. A backend can still choose to implement them individually, of course, and the CIFS backend does that. - simplified the generic structures to make them identical to the principal call for several common SMB calls (such as RAW_WRITE_GENERIC now being an alias for RAW_WRITE_WRITEX). - started rewriting the pvfs_open() code in preparation for the full ntcreatex semantics. - in pvfs_open and ipc_open, initially allocate the open file structure as a child of the request, so on error we don't need to clean up. Then when we are going to succeed the open steal the pointer into the long term backend context. This makes for much simpler error handling (and fixes some bugs) - use a destructor in the ipc backend to make sure that everthing is cleaned up on receive error conditions. - switched the ipc backend to using idtree for fnum allocation - in the ntvfs_generic mapping routines, use a allocated secondary structure not a stack structure to ensure the request pointer remains valid even if the backend replies async. (This used to be commit 3457c1836c09c82956697eb21627dfa2ed37682e)
2007-10-10r3056: added a id -> pointer data structure (a type of radix tree). This isAndrew Tridgell1-23/+41
an extremely efficient way of mapping from an integer handle (such as an open file handle) to a pointer (such as the structure containing the open file information). 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. (This used to be commit 16835a0ef91a16fa01145b773aad8d43da215dbf)
2007-10-10r3035: if the ntvfs layers prior to us have said that we can't perform anAndrew Tridgell1-1/+2
operation asynchronously (such as the nbench module), then ignore lock timeouts, as they would make no sense (This used to be commit 2894dd0ac0ddd0ae5b4d536d5cff0690bbfab1a0)
2007-10-10r3034: - fixed a bug in message dispatch, when the dispatch function called ↵Andrew Tridgell1-13/+33
messaging_deregister() - added a pvfs_lock_close_pending() hook to remove pending locks on file close - fixed the private ptr argument to messaging_deregister() in pvfs_wait - fixed a bug in continuing lock requests after a lock that is blocking a pending lock is removed - removed bogus brl_unlock() call in lock continue - corrected error code for LOCKING_ANDX_CHANGE_LOCKTYPE - expanded the lock cancel test suite to test lock cancel by unlock and by close - added a testsuite for LOCKING_ANDX_CHANGE_LOCKTYPE (This used to be commit 5ef80f034d4aa4dd6810532c63ad041bfc019cb8)
2007-10-10r3031: added support for lock cancelation, which effectively just triggers ↵Andrew Tridgell1-6/+53
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 Tridgell1-4/+182
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/+151
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)
