2007-10-10r23792: convert Samba4 to GPLv3Andrew Tridgell1-3/+2
There are still a few tidyups of old FSF addresses to come (in both s3 and s4). More commits soon. (This used to be commit fcf38a38ac691abd0fa51b89dc951a08e89fdafa)
2007-10-10r20624: added AIO read to pvfs backendAndrew Tridgell1-1/+11
(This used to be commit d6e20d6d8c5c207e7f04b0d0523224437b209917)
2007-10-10r18835: expand IO limits on SMB2. Samba4 now tops out at 16.7MB IOs.Andrew Tridgell1-1/+1
(This used to be commit 1e34e4d5a1fd3d74080424140e4ab276b6042d12)
2007-10-10r15734: This is a major change to the NTVFS subsystem:Stefan Metzmacher1-1/+1
- 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)
2007-10-10r14933: fix the handling of notify filters to be much closer to the behaviourAndrew Tridgell1-5/+0
of w2k3. The behaviour is particularly tricky for rename. (This used to be commit 4d3b8d95498a328ffc08ecb62d9531b6bfe4e2b5)
2007-10-10r14797: added checking of the filter in notify requestsAndrew Tridgell1-0/+5
(This used to be commit 1db0a5a7f4c1ff915d91bc15d8e40cc90a78961d)
2007-10-10r14464: Don't include ndr_BASENAME.h files unless strictly required, insteadJelmer Vernooij1-1/+1
try to include just the BASENAME.h files (containing only structs) (This used to be commit 3dd477ca5147f28a962b8437e2611a8222d706bd)
2007-10-10r14256: - rename smb_file -> smb_handleStefan Metzmacher1-1/+1
- move it into the in/out substructs again - allow file.path only on smb_fileinfo/smb_setfileinfo metze (This used to be commit be6d5298a2cdb7e7c61d70471bad445645af5963)
2007-10-10r14208: removed use of req->flags2 inside the ntvfs layer. This should helpAndrew Tridgell1-1/+1
metze on his quest to unify the ntvfs strucures for the smb and smb2 servers. The only place we needed flags2 inside ntvfs was for the FLAGS2_READ_PERMIT_EXECUTE bit, which only affects readx, so I added a readx.in.read_for_execute flag instead. (This used to be commit b78abbbce60ab0009da19a72dd769800c44298a2)
2007-10-10r14173: change smb interface structures to always useStefan Metzmacher1-1/+1
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 Metzmacher1-2/+2
(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)
2007-10-10r5298: - got rid of pstring.h from includes.h. This at least makes it a bitAndrew Tridgell1-1/+0
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)
2007-10-10r4011: get rid of rpc_secdes.h and replace it with a single sane set ofAndrew Tridgell1-2/+3
definitions for security access masks, in security.idl The previous definitions were inconsistently named, and contained many duplicate and misleading entries. I kept finding myself tripping up while using them. (This used to be commit 01c0fa722f80ceeb3f81f01987de95f365a2ed3d)
2007-10-10r3798: added support for alternate data streams in xattrs into pvfs.Andrew Tridgell1-4/+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)
2007-10-10r3618: - this adds the special case for DENY_DOS semantics, as shown by the ↵Andrew Tridgell1-1/+1
BASE-DENYDOS test. - pvfs now passes BASE-DENY1 and BASE-DENYDOS. (This used to be commit aa09df22ee729c02552638859236d9068e9748ae)
2007-10-10r3615: split out struct pvfs_file_handle from struct pvfs_file. This is inAndrew Tridgell1-4/+4
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)
2007-10-10r3544: fixed some #include lines to make them more consistentAndrew Tridgell1-1/+1
(This used to be commit a1a0118bd3f1cae034a1c564d05c3aa8019ff932)

2007-10-10r3387: fixed pvfs to pass the NTDENY tests. The tricky bit wasAndrew Tridgell1-2/+7
SA_RIGHT_FILE_EXECUTE, which depends on a flags2 bit (This used to be commit c36851d230bcf552ed79322f8358060ab164ec09)
2007-10-10r3363: added basic support for SA_RIGHT_FILE_EXECUTE, needed for opening ↵Andrew Tridgell1-1/+1
.dll files (This used to be commit ba1bfd51e1b694cb69afe559f695addaf03b4d81)
2007-10-10r3241: don't skip the read completely for a zero-length read, as it could ↵Andrew Tridgell1-8/+7
give a lock conflict (This used to be commit 7ce6139f984c72a6347c7a64d95d5278bcf3e868)
2007-10-10r3240: - update the rules for what error codes should be given on theAndrew Tridgell1-1/+8
different type of unlink an seach mismatches - wildcard directory listings that have attribute FILE_ATTRIBUTE_DIRECTORY and match "." or ".." should be failed. - don't set the write_time on SMBclose unless it is non-zero - added much better support for setfileinfo and setpathinfo in pvfs - better (and more efficient) handling of .. and . components in filenames (This used to be commit 9305b07af395a158cb9f0c1c9486f7122c79d357)
2007-10-10r3161: pvfs now passes the RAW-SEEK testAndrew Tridgell1-0/+2
(This used to be commit a953d4a42c8fa3fe930c319d5157fc406a1035da)
2007-10-10r3147: added basic share modes support for pvfs (or more precisely, ntcreatexAndrew Tridgell1-0/+4
share_access support). This is enough for us to pass the BASE-DENY2 test, but is a long way from fully correct share modes. (This used to be commit b5a6dd3cbf28a3a3b3a3656042ac8f50fca29e1c)
2007-10-10r3081: several updates to ntvfs and server side async request handling inAndrew Tridgell1-2/+5
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)
2007-10-10r3012: added initial support for byte range locking in the posix vfs. This isAndrew Tridgell1-0/+9
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)
2007-10-10r2751: this is a new ntvfs design which tries to solve:Stefan Metzmacher1-3/+4
- the stacking of modules - finding the modules private data - hide the ntvfs details from the calling layer - I set NTVFS_INTERFACE_VERSION 0 till we are closer to release (because we need to solve some async problems with the module stacking) metze (This used to be commit 3ff03b5cb21bb79afdd3b1609be9635f6688a539)
2007-10-10r2660: - converted the libcli/raw/ library to use talloc_increase_ref_count()Andrew Tridgell1-1/+2
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)
2007-10-10r2561: completely redid the ntvfs module chaining code, You can now do ↵Andrew Tridgell1-1/+1
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)
2007-10-10r2436: the second big lump of posix vfs code.Andrew Tridgell1-0/+57
this is still just a skeleton, and many of the functions are just based on the simple vfs backend, they are there to allow me to run smbtorture tests against the real parts of the posix backend. (This used to be commit f2fa7fe565e89360dba3bb5434d3a6a36f398348)
