SMB1 already supports querying reparse points and detecting types of symlink, fifo, socket, block and char. This change implements the missing part - ability to create a new reparse points over SMB1. This includes everything which SMB2+ already supports: - native SMB symlinks and sockets - NFS style of special files (symlinks, fifos, sockets, char/block devs) - WSL style of special files (symlinks, fifos, sockets, char/block devs) Attaching a reparse point to an existing file or directory is done via SMB1 SMB_COM_NT_TRANSACT/NT_TRANSACT_IOCTL/FSCTL_SET_REPARSE_POINT command and implemented in a new cifs_create_reparse_inode() function. This change introduce a new callback ->create_reparse_inode() which creates a new reperse point file or directory and returns inode. For SMB1 it is provided via that new cifs_create_reparse_inode() function. Existing reparse.c code was only slightly updated to call new protocol callback ->create_reparse_inode() instead of hardcoded SMB2+ function. This make the whole reparse.c code to work with every SMB dialect. The original callback ->create_reparse_symlink() is not needed anymore as the implementation of new create_reparse_symlink() function is dialect agnostic too. So the link.c code was updated to call that function directly (and not via callback). Signed-off-by: Pali Rohár <pali@kernel.org> Signed-off-by: Steve French <stfrench@microsoft.com>
