* Rename vfs operation posix_fallocate to just fallocate and add the ↵Jeremy Allison2010-12-181-4/+4
| | | | | | | | | | | | | | | | | | | | | | vfs_fallocate_mode parameter. It turns out we need the fallocate operations to be able to both allocate and extend filesize, and to allocate and not extend filesize, and posix_fallocate can only do the former. So by defining the vfs op as posix_fallocate we lose the opportunity to use any underlying syscalls (like Linux fallocate) that can do the latter as well. We don't currently use the non-extending filesize call, but now I've changed the vfs op definition we can in the future. For the moment simply map the fallocate op onto posix_fallocate for the VFS_FALLOCATE_EXTEND_SIZE case and return ENOSYS for the VFS_FALLOCATE_KEEP_SIZE case. Jeremy.

| | | | | | | | | | Ensure we don't use any of the create_options for Samba private use. Add a new parameter to the VFS_CREATE call (private_flags) which is only used internally. Renumber NTCREATEX_OPTIONS_PRIVATE_DENY_DOS and NTCREATEX_OPTIONS_PRIVATE_DENY_FCB to match the S4 code). Rev. the VFS interface to version 28. Jeremy.

* vfs catia: Fix the double translation that was happening with createfile and ↵Aravind Srinivasan2009-09-241-4/+4
| | | | | | | | | | | | | | | open. Since the catia translation is implemented for open, it should not also be done in createfile. By removing createfile from catia, translation is now done correctly for the primary open path. In order to support systems that have custom createfile implementations that don't eventually call SMB_VFS_OPEN, SMB_VFS_TRANSLATE_NAME has been expanded to take an additional argument that specifies direction.

* s3: Add a new VFS op called SMB_VFS_TRANSLATE_NAMEAravind Srinivasan2009-08-281-0/+8
| | | | | | | | | | | This vop is designed to work in tandem with SMB_VFS_READDIR to allow vfs modules to make modifications to arbitrary filenames before they're consumed by callers. Subsequently the core directory enumeration code in smbd is now changed to free the memory that may be allocated in a module. This vop enables the new version of catia in the following patch.

* s3: Plumb smb_filename through SMB_VFS_STAT and SMB_VFS_LSTATTim Prouty2009-06-241-6/+6
| | | | | | | | | | | | | This patch introduces two new temporary helper functions vfs_stat_smb_fname and vfs_lstat_smb_fname. They basically allowed me to call the new smb_filename version of stat, while avoiding plumbing it through callers that are still too inconvenient. As the conversion moves along, I will be able to remove callers of this, with the goal being to remove all callers. There was also a bug in create_synthetic_smb_fname_split (also a temporary utility function) that caused it to incorrectly handle filenames with ':'s in them when in posix mode. This is now fixed.

* Add VFS ops for Windows BRL: Lock, Unlock and Cancel:Zack Kirsch2009-02-131-0/+9
| | | | | | | | | | | | | | | | | | | | | | | This patch adds 3 new VFS OPs for Windows byte range locking: BRL_LOCK_WINDOWS, BRL_UNLOCK_WINDOWS and BRL_CANCEL_WINDOWS. Specifically: * I renamed brl_lock_windows, brl_unlock_windows and brl_lock_cancel to *_default as the default implementations of the VFS ops. * The blocking_lock_record (BLR) is now passed into the brl_lock_windows and brl_cancel_windows paths. The Onefs implementation uses it - future implementations may find it useful too. * Created brl_lock_cancel to do what brl_lock/brl_unlock do: set up a lock_struct and call either the Posix or Windows lock function. These happen to be the same for the default implementation. * Added helper functions: increment_current_lock_count() and decrement_current_lock_count(). * Minor spelling correction in brl_timeout_fn: brl -> blr. * Changed blocking_lock_cancel() to return the BLR that it has cancelled. This allows us to assert its the lock that we wanted to cancel. If this assert ever fires, this path will need to take in the BLR to cancel, rather than choosing on its own. * Adds a small helper function: find_blocking_lock_record_by_id(). Used by the OneFS implementation, but could be useful for others.

* Add an optional SMB_STRUCT_SMB parameter to VFS_OP_READDIRSteven Danneman2009-02-091-4/+4

* Pass the get_real_filename operation through the VFSVolker Lendecke2008-12-101-0/+3
| | | | | | | | | | | | | | This is done to help file systems that can tell us about the real upper/lower case combination given a case-insensitive file name. The sample I will soon push is the gpfs module (recent gpfs has a get_real_filename function), others might have a similar function to help alleviate the 1million files in a single directory problem. Jeremy, please comment! Thanks, Volker
* s3: Change SMB_VFS_CREATE_FILE to take a create_file_flags argumentTim Prouty2008-12-031-3/+3
| | | | | | This replaces the is_dos_path bool with a more future-proof argument. The next step is to plumb INTERNAL_OPEN_ONLY through this flag instead of overridding the oplock_request.
* s3: Add new "is_dos_path" argument to SMB_VFS_CREATE_FILETim Prouty2008-12-031-3/+3

* Yay ! Remove a VFS entry. Removed the set_nt_acl() call,Jeremy Allison2008-05-081-3/+0
| | | | | | | | | | | | | | | this can only be done via fset_nt_acl() using an open file/directory handle. I'd like to do the same with get_nt_acl() but am concerned about efficiency problems with "hide unreadable/hide unwritable" when doing a directory listing (this would mean opening every file in the dir on list). Moving closer to rationalizing the ACL model and maybe moving the POSIX calls into a posix_acl VFS module rather than having them as first class citizens of the VFS. Jeremy.

| | | | | | | | | | | | | handle FS capabilities. As discussed with Volker, it is better to calculate FS capabilities at connection time. We already do this with help of VFS statvfs() call which allows to fill-in system-specific attributes including FS capabilities. So just re-use it if you want to represent additional capabilities in your modules. The only caution is that you need to call underlying statvfs() call to actually get system-specific capabilities (and other fields) added. Then add module-specific ones.

* Rework of VFS is_offline() function to only return boolean offline/online ↵Alexander Bokovoy2008-01-171-3/+3
| | | | | | | | | | | | | | | result for a file. This makes sense as upper levels are only taking returned result of 0 (no error) into consideration when deciding whether to mark file offline/online as returned from is_offline. That means that we simply can move the decision down to VFS module and clean up upper levels so that they always see only file status. If there is an error when trying to identify file status, then VFS module could decide what to return (offline or online) by itself -- after all, it ought to have system-specific knowledge anyway.

* Add support for offline files support, remote storage, and Async I/O force ↵Alexander Bokovoy2008-01-161-0/+18
| | | | | | | | | | | | | | | | | operations to VFS Offline files support and remote storage are for allowing communication with backup and archiving tools that mark files moved to a tape library as offline. We translate this info into corresponding CIFS offline file attribute and mark an exported volume as remote storage. Async I/O force is to allow selective redirection of I/O operations to asynchronous processing in case it is viable at VFS module discretion. It is needed for proper handling of offline files as performing regular I/O on offline file will block smbd.
