2009-09-24vfs catia: Fix the double translation that was happening with createfile and ↵Aravind Srinivasan1-2/+9
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.

2009-08-28s3: Add a new VFS op called SMB_VFS_TRANSLATE_NAMEAravind Srinivasan1-0/+7
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.

2009-06-24s3: Plumb smb_filename through SMB_VFS_STAT and SMB_VFS_LSTATTim Prouty1-3/+3
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.
2009-06-17s3: Change SMB_VFS_OPEN to take an smb_filename structTim Prouty1-2/+5
This was a little messy because of all of the vfs modules I had to touch. Most of them were pretty straight forward, but the streams modules required a little attention to handle smb_filename. Since the use of smb_filename enables the vfs modules to access the raw, over-the-wire stream, a little bit of the handling that was being done by split_ntfs_stream_name has now been shifted into the individual stream modules. It may be a little more code, but overall it gives more flexibility to the streams modules, while also allowing correct stream handling.

2009-06-02Add SMB_VFS_CONNECTPATH operationVolker Lendecke1-0/+5
This is required for the shadow_copy2 module and "wide links = no". The file system snapshots by nature are typically outside of share directory. So the REALPATH result fails the wide links = no test.
2009-03-13s3: Add strict lock/unlock calls to the vfs layer to replace is_lockedDave Richards1-0/+13
2009-02-19s3: Modify SMB_VFS_FILE_ID_CREATE to take a stat structTim Prouty1-1/+2
Since file_id_create_dev is incompatible with the concept of file_ids, it is now static and in the one file that needs it.
2009-02-13Add VFS ops for Windows BRL: Lock, Unlock and Cancel:Zack Kirsch1-0/+24
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.
2009-02-09s3: OneFS bulk directory enumeration supportSteven Danneman1-1/+1
OneFS provides the bulk directory enumeration syscall readdirplus(). This syscall has the same semantics as the NFSv3 READDIRPLUS command, returning a batch of directory entries with prefetched stat information via one syscall. This commit wraps the readdirplus() call in the existing POSIX readdir/seekdir VFS interface. By default a batch of 128 directory entries are optimistically read from the kernel into a global cache, and fed to iterative calls of VFS_OP_READDIR. The global buffers could be avoided in the future by hanging connection specific buffers off the conn struct. Added new parameter "onefs:use readdirplus" which toggles usage of this code on or off.
2009-02-09s3: Added SMB_VFS_INIT_SEARCH_OP to initialize data at the beginning of SMB ↵Steven Danneman1-2/+6
search requests. By default this VFS call is a NOOP, but the onefs vfs module takes advantage of it to initialize direntry search caches at the beginning of each TRANS2_FIND_FIRST, TRANS2_FIND_NEXT, SMBffirst, SMBsearch, and SMBunique
2009-02-09Add an optional SMB_STRUCT_SMB parameter to VFS_OP_READDIRSteven Danneman1-1/+4
* this allows VFS implementations that prefetch stat information on readdir to return it through one VFS call * backwards compatibility is maintained by passing in NULL * if the system readdir doesn't return stat info, the stat struct is set to invalid
2009-02-09s3 vfs: Add a destructor to the fsp extension data APITim Prouty1-2/+2
I'm not certain if the dummy pointer is needed in struct vfs_fsp_data, but I added it to be consistent with the comment below.
2009-01-29s3: Add a new SMB_VFS_GET_ALLOC_SIZE vfs operationTim Prouty1-0/+4
This allows module implementors to customize what allocation size is returned to the client.
2009-01-23Extend NTIMES to allow setting create_timetodd stecher1-1/+3
1) Add in smb_file_time struct to clarify code and make room for createtime. 2) Get and set create time from SMB messages. 3) Fixup existing VFS modules + examples Some OS'es allow for the setting of the birthtime through kernel interfaces. This value is generically used for Windows createtime, but is not settable in the code today.
2008-12-10Pass the get_real_filename operation through the VFSVolker Lendecke1-0/+8
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
2008-12-03s3: Change SMB_VFS_CREATE_FILE to take a create_file_flags argumentTim Prouty1-1/+1
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.
2008-12-03s3: Add new "is_dos_path" argument to SMB_VFS_CREATE_FILETim Prouty1-0/+1
Now unix paths can be differentiated from windows paths so the underlying create_file implementations can convert paths correctly.

2008-05-08Yay ! Remove a VFS entry. Removed the set_nt_acl() call,Jeremy Allison1-8/+3
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.

2008-01-21Add SMB_VFS_FS_CAPABILITIESVolker Lendecke1-0/+3
It turns out that this is a necessary operation, separate from statvfs. statvfs can fail during tcon, so conn->fs_capabilities would never see that we support streams on a particular share.

2008-01-17Remove is_remotestorage() call from VFS. We already have statvfs() there to ↵Alexander Bokovoy1-4/+0
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. (This used to be commit e342ca0d931f9a5c8ec9e472dc9c63f1fe012b3a)
2008-01-17Rework of VFS is_offline() function to only return boolean offline/online ↵Alexander Bokovoy1-1/+1
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.

2008-01-16Add support for offline files support, remote storage, and Async I/O force ↵Alexander Bokovoy1-0/+19
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.
