2022-08-06vfs: change openat propotype to match linux openat2Volker Lendecke1-6/+5
The Linux prototype for openat2 looks like this: long openat2(int dirfd, const char *pathname, struct open_how *how, size_t size); where "struct open_how" is defined in "linux/openat2.h". It is designed to be extensible with further flags. The "size" parameter is required because there is no type checking between userland and kernelspace, so the way for Linux to find which version of open_how is being passed in is looking at the size: "open_how" is expected to only every grow with additional fields, should a change be necessary in the future. Samba does not have this problem, we can typecheck the struct and pointers, we expect all VFS modules to be compiled against the current vfs.h. For now this adds no functionality, but it will make further patches much smaller.

2020-12-16smbd: use fsp_get_io_fd() when accessing a file or it's associated metadataRalph Boehme1-1/+1
In all places where we access or modify a file or it's associated metadata, we use fsp_get_io_fd() to fetch the low-level fd from the fsp. This ensures we don't accidentally use a pathref fsp where the fd would be opened as root on systems lacking O_PATH.

XXX_init(TALLOC_CTX *) Not currently used - no logic changes inside. This will make it possible to pass down a long-lived talloc context from the loading function for modules to use instead of having them internally all use talloc_autofree_context() which is a hidden global.

2015-02-11vfs_prealloc: Remove call to gpfs_preallocChristof Schmitt1-9/+0
Calling gpfs_prealloc changes the actual size of the file, and this should not be done implicitly. Also this code does not compile due to the missing dependency to the gpfs library. The best way solution here is probably removing the call to gpfs_prealloc. The vfs_gpfs module already implements the call to gpfs_prelloc when this can be done safely.

2009-06-17s3: Change SMB_VFS_OPEN to take an smb_filename structTim Prouty1-6/+7
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.
