2013-01-16s3-vfs: add copy_chunk vfs hooksDavid Disseldorp1-0/+10
copy_chunk copies n bytes from a source file at a specific offset to a destination file at a given offset. This interface will be used in handling smb2 FSCTL_SRV_COPYCHUNK ioctl requests. Use a pread/pwrite loop in vfs_default, so that requests referring to the same src and dest file are possible. Provide send and receive hooks for copy chunk VFS interface, allowing asynchronous behaviour. Check whether the request source offset + length exceeds the current size. Return STATUS_INVALID_VIEW_SIZE under such a condition, matching Windows server behaviour. Reviewed by: Jeremy Allison <jra@samba.org>
2012-10-11vfs: Remove type parameter from sys_acl_blob_get_{fd,file}Andrew Bartlett1-4/+4
This interface actually needs to match the get_nt_acl interface in that the system ACL implmenetation may not be posix ACLs, and the blob is not meant to be enforced to be of a particular system ACL structure. Andrew Bartlett
2012-10-11smbd: Add mem_ctx to {f,}get_nt_acl VFS callAndrew Bartlett1-9/+9
This makes it clear which context the returned SD is allocated on, as a number of callers do not want it on talloc_tos(). As the ACL transformation allocates and then no longer needs a great deal of memory, a talloc_stackframe() call is used to contain the memory that is not returned further up the stack. Andrew Bartlett
2012-10-11smbd: Add mem_ctx to sys_acl_init() and all callersAndrew Bartlett1-9/+9
This changes from allocation on NULL to allocation on the supplied memory context. Currently that supplied context is talloc_tos() at the the final consumer of the ACL. Andrew Bartlett
2012-09-12smbd: Add extra VFS hooks to get the posix ACL as a blobAndrew Bartlett1-0/+10
This will allow us to hash this, rather than the NT ACL it maps to. This will in turn allow us to know if the NT ACL is valid even if we have to change the mapping code.

2012-09-08s3:vfs: add durable VFS operationsMichael Adam1-0/+25
This allows a VFS module to implement durable handles in different ways. Pair-Programmed-With: Stefan Metzmacher <metze@samba.org>
2012-08-15s3-smbd: Remove sys_acl_*() VFS wrapper functionsAndrew Bartlett1-85/+0
We no longer do struct smb_acl_t manipuations via the VFS layer, which is now reduced to handling the get/set functions. The only backend that implemented these functions (aside from audit) was the vfs_default module calling the sys_acl code. The various ACL implementation modules either worked on the fully initilaised smb_acl_t object or on NT ACLs. This not only makes the operation of the posix ACL code more efficient (as allocation and free is not put via the VFS), it makes it easier to test and removes the fantasy that a module could safely redefine this structure or the behaviour here. The smb_acls.idl now defines the structure, and it is now allocated with talloc. These operations were originally added to the VFS in commit 3bb219161a270f12c27c3bc7e1220829c6e9f284. Andrew Bartlett

2012-03-26s3: Pass filters explicitly through vfs notify watchVolker Lendecke1-4/+4
This removes a dependency on "struct notify_entry" and makes the nature of the API more explicit. We depend upon the VFS module to mask out elements from e->filter and e->subdir_filter that it took over to handle.

2010-12-18Rename vfs operation posix_fallocate to just fallocate and add the ↵Jeremy Allison1-4/+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.

2009-09-24vfs catia: Fix the double translation that was happening with createfile and ↵Aravind Srinivasan1-4/+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.

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

2009-06-24s3: Plumb smb_filename through SMB_VFS_STAT and SMB_VFS_LSTATTim Prouty1-6/+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.

2009-02-13Add VFS ops for Windows BRL: Lock, Unlock and Cancel:Zack Kirsch1-0/+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.

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 Danneman1-4/+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
2009-01-29s3: Add a new SMB_VFS_GET_ALLOC_SIZE vfs operationTim Prouty1-0/+3

2008-12-10Pass the get_real_filename operation through the VFSVolker Lendecke1-0/+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
