* vfs: add [GET/SET]_COMPRESSION hooksDavid Disseldorp2013-11-222-0/+40
| | | | | | | | | | | | | | | The VFS interfaces are sychronous, as the operations only modify meta-data. These hooks are dependent on support for transparent compression by the underlying filesystem - vfs_default returns INVALID_DEVICE_REQUEST. Support for other filesystems providing transparent comression, such as Btrfs and ZFS, can be added in future. The get_compression function takes fsp and smb_fname arguments. The smb_fname argument is needed due to the current dosmode() code-path. Signed-off-by: David Disseldorp <ddiss@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>

* s3-vfs: add copy_chunk vfs hooksDavid Disseldorp2013-01-162-0/+117
| | | | | | | | | | | | | | | | | | 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>
* examples: Re-indent and reformat skel VFS modulesAndrew Bartlett2012-10-112-348/+436
| | | | | | This avoids some of the poor style here from propogating to new VFS modules. Andrew Bartlett
* vfs: Remove type parameter from sys_acl_blob_get_{fd,file}Andrew Bartlett2012-10-112-3/+3
| | | | | | | | | 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
* smbd: Add mem_ctx to {f,}get_nt_acl VFS callAndrew Bartlett2012-10-112-6/+14
| | | | | | | | | | | 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
* smbd: Add mem_ctx to sys_acl_init() and all callersAndrew Bartlett2012-10-112-6/+16
| | | | | | | | | | 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
* smbd: Add extra VFS hooks to get the posix ACL as a blobAndrew Bartlett2012-09-122-0/+33
| | | | | | | | | | | 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.

* s3-smbd: Remove sys_acl_*() VFS wrapper functionsAndrew Bartlett2012-08-152-221/+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

| | | | | | | | | | | | | | | | | | | | | | 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.
