| | | | | | | | | | | | | As per MS-SMB2 and MS-FSA and our SMB_VFS_STRICT_LOCK implementation, we're merely testing for locks, not setting any.

* s3/smbd: remove unneeded flags argument from SMB_VFS_OFFLOAD_WRITE_SENDRalph Boehme2017-07-032-5/+3
| | | | | | | | | | | | ...and instead use the fsctl to infer required behaviour in the VFS backends. Note that this removes the check from vfs_default because there we only handle FSCTL_SRV_COPYCHUNK(_WRITE) and must always perform the lock checks.

* s3/vfs: make SMB_VFS_OFFLOAD_WRITE_SEND offload token basedRalph Boehme2017-07-032-5/+7
| | | | | | | | | | | | | Remove the source fsp argument and instead pass the offload token generated with SMB_VFS_OFFLOAD_READ_SEND/RECV. An actual offload fsctl is not implemented yet, neither in the VFS nor at the SMB ioctl layer, and returns NT_STATUS_NOT_IMPLEMENTED With these changes we now pass the copy-chunk-across-shares test.

* s3/vfs: add SMB_VFS_OFFLOAD_READ_SEND/RECVRalph Boehme2017-07-032-0/+134
| | | | | | | | | | | | | | | | | | Add SMB_VFS_OFFLOAD_READ_SEND an SMB_VFS_OFFLOAD_READ_RECV. This paves the way for supporting server-side copy-chunk with source and destination file-handles on different shares. It can be used to implement copy offload fsctl in the future, but for now this will be used as a mere copy-chunk replacement. SMB_VFS_OFFLOAD_READ generates a token that associates an fsp with the token and stores the fsp in a in-memory db. Initially only a copy-chunk resume key fsctl is supported. In the future this can be enhanced to support real offload fsctl. Signed-off-by: Ralph Boehme <slow@samba.org> Reviewed-by: Stefan Metzmacher <metze@samba.org>

* vfs: add snapshot create/delete hooksDavid Disseldorp2015-03-312-0/+62
| | | | | | | | | | | | | | | | | | | | | | | This change adds three new VFS hooks covering snapshot manipulation: - snap_check_path Check whether a path supports snapshots. - snap_create Request the creation of a snapshot of the provided path. - snap_delete Request the deletion of a snapshot. These VFS call-outs will be used in future by Samba's File Server Remote VSS Protocol (FSRVP) server. MS-FSVRP states: At any given time, Windows servers allow only one shadow copy set to be going through the creation process. Therefore, only provide synchronous hooks for now, which can be converted to asynchronous _send/_recv functions when the corresponding DCE/RPC server infrastructure is in place.

| | | | | | | | | | | | | | | | | | | | The Linux fallocate syscall offers a mode parameter which can take the following flags: FALLOC_FL_KEEP_SIZE FALLOC_FL_PUNCH_HOLE (since 2.6.38) FALLOC_FL_COLLAPSE_RANGE (since 3.15) FALLOC_FL_ZERO_RANGE (since 3.14) The flags are not exclusive, e.g. FALLOC_FL_PUNCH_HOLE must be specified alongside FALLOC_FL_KEEP_SIZE. Samba currently takes a vfs_fallocate_mode enum parameter for the VFS fallocate hook, taking either an EXTEND_SIZE or KEEP_SIZE value.
