/**
 * union security_list_options - Linux Security Module hook function list
 *
 * Security hooks for program execution operations.
 *
 * @bprm_set_creds:
 *	Save security information in the bprm->security field, typically based
 *	on information about the bprm->file, for later use by the apply_creds
 *	hook.  This hook may also optionally check permissions (e.g. for
 *	transitions between security domains).
 *	This hook may be called multiple times during a single execve, e.g. for
 *	interpreters.  The hook can tell whether it has already been called by
 *	checking to see if @bprm->security is non-NULL.  If so, then the hook
 *	may decide either to retain the security information saved earlier or
 *	to replace it.  The hook must set @bprm->secureexec to 1 if a "secure
 *	exec" has happened as a result of this hook call.  The flag is used to
 *	indicate the need for a sanitized execution environment, and is also
 *	passed in the ELF auxiliary table on the initial stack to indicate
 *	whether libc should enable secure mode.
 *	@bprm contains the linux_binprm structure.
 *	Return 0 if the hook is successful and permission is granted.
 * @bprm_check_security:
 *	This hook mediates the point when a search for a binary handler will
 *	begin.  It allows a check the @bprm->security value which is set in the
 *	preceding set_creds call.  The primary difference from set_creds is
 *	that the argv list and envp list are reliably available in @bprm.  This
 *	hook may be called multiple times during a single execve; and in each
 *	pass set_creds is called first.
 *	@bprm contains the linux_binprm structure.
 *	Return 0 if the hook is successful and permission is granted.
 * @bprm_committing_creds:
 *	Prepare to install the new security attributes of a process being
 *	transformed by an execve operation, based on the old credentials
 *	pointed to by @current->cred and the information set in @bprm->cred by
 *	the bprm_set_creds hook.  @bprm points to the linux_binprm structure.
 *	This hook is a good place to perform state changes on the process such
 *	as closing open file descriptors to which access will no longer be
 *	granted when the attributes are changed.  This is called immediately
 *	before commit_creds().
 * @bprm_committed_creds:
 *	Tidy up after the installation of the new security attributes of a
 *	process being transformed by an execve operation.  The new credentials
 *	have, by this point, been set to @current->cred.  @bprm points to the
 *	linux_binprm structure.  This hook is a good place to perform state
 *	changes on the process such as clearing out non-inheritable signal
 *	state.  This is called immediately after commit_creds().
 *
 * Security hooks for filesystem operations.
 *
 * @sb_alloc_security:
 *	Allocate and attach a security structure to the sb->s_security field.
 *	The s_security field is initialized to NULL when the structure is
 *	allocated.
 *	@sb contains the super_block structure to be modified.
 *	Return 0 if operation was successful.
 * @sb_free_security:
 *	Deallocate and clear the sb->s_security field.
 *	@sb contains the super_block structure to be modified.
 * @sb_statfs:
 *	Check permission before obtaining filesystem statistics for the @mnt
 *	mountpoint.

 *	Return 0 if permission is granted.
 * @sb_mount:
 *	Check permission before an object specified by @dev_name is mounted on
 *	the mount point named by @nd.  For an ordinary mount, @dev_name
 *	identifies a device if the file system type requires a device.  For a
 *	remount (@flags & MS_REMOUNT), @dev_name is irrelevant.  For a
 *	loopback/bind mount (@flags & MS_BIND), @dev_name identifies the
 *	pathname of the object being mounted.
 *	@dev_name contains the name for object being mounted.
 *	@path contains the path for mount point object.
 *	@type contains the filesystem type.
 *	@flags contains the mount flags.
 *	@data contains the filesystem-specific data.
 *	Return 0 if permission is granted.
 * @sb_copy_data:
 *	Allow mount option data to be copied prior to parsing by the filesystem,
 *	so that the security module can extract security-specific mount
 *	options cleanly (a filesystem may modify the data e.g. with strsep()).
 *	This also allows the original mount data to be stripped of security-
 *	specific options to avoid having to make filesystems aware of them.
 *	@type the type of filesystem being mounted.
 *	@orig the original mount data copied from userspace.
 *	@copy copied data which will be passed to the security module.
 *	Returns 0 if the copy was successful.
 * @sb_remount:
 *	Extracts security system specific mount options and verifies no changes
 *	are being made to those options.
 *	@sb superblock being remounted
 *	@data contains the filesystem-specific data.
 *	Return 0 if permission is granted.
 * @sb_umount:
 *	Check permission before the @mnt file system is unmounted.
 *	@mnt contains the mounted file system.
 *	@flags contains the unmount flags, e.g. MNT_FORCE.
 *	Return 0 if permission is granted.
 * @sb_pivotroot:
 *	Check permission before pivoting the root filesystem.
 *	@old_path contains the path for the new location of the
 *	current root (put_old).
 *	@new_path contains the path for the new root (new_root).
 *	Return 0 if permission is granted.
 * @sb_set_mnt_opts:
 *	Set the security relevant mount options used for a superblock
 *	@sb the superblock to set security mount options for
 *	@opts binary data structure containing all lsm mount data
 * @sb_clone_mnt_opts:
 *	Copy all security options from a given superblock to another
 *	@oldsb old superblock which contain information to clone
 *	@newsb new superblock which needs filled in
 * @sb_parse_opts_str:
 *	Parse a string of security data filling in the opts structure
 *	@options string containing all mount options known by the LSM
 *	@opts binary data structure usable by the LSM
 * @dentry_init_security:
 *	Compute a context for a dentry as the inode is not yet available
 *	since NFSv4 has no label backed by an EA anyway.
 *	@dentry dentry to use in calculating the context.
 *	@mode mode used to determine resource type.
 *	@name name of the last path component used to create file
 *	@ctx pointer to place the pointer to the resulting context in.
 *	@ctxlen point to place the length of the resulting context.
 * @dentry_create_files_as:
 *	Compute a context for a dentry as the inode is not yet available
 *	and set that context in passed in creds so that new files are
 *	created using that context. Context is calculated using the
 *	passed in creds and not the creds of the caller.
 *	@dentry dentry to use in calculating the context.
 *	@mode mode used to determine resource type.
 *	@name name of the last path component used to create file
 *	@old creds which should be used for context calculation
 *	@new creds to modify
 *
 *
 * Security hooks for inode operations.
 *
 * @inode_alloc_security:
 *	Allocate and attach a security structure to @inode->i_security.  The
 *	i_security field is initialized to NULL when the inode structure is
 *	allocated.
 *	@inode contains the inode structure.
 *	Return 0 if operation was successful.
 * @inode_free_security:
 *	@inode contains the inode structure.
 *	Deallocate the inode security structure and set @inode->i_security to
 *	NULL.
 * @inode_init_security:
 *	Obtain the security attribute name suffix and value to set on a newly
 *	created inode and set up the incore security field for the new inode.
 *	This hook is called by the fs code as part of the inode creation
 *	transaction and provides for atomic labeling of the inode, unlike
 *	the post_create/mkdir/... hooks called by the VFS.  The hook function
 *	is expected to allocate the name and value via kmalloc, with the caller
 *	being responsible for calling kfree after using them.
 *	If the security module does not use security attributes or does
 *	not wish to put a security attribute on this particular inode,
 *	then it should return -EOPNOTSUPP to skip this processing.
 *	@inode contains the inode structure of the newly created inode.
 *	@dir contains the inode structure of the parent directory.

 *
 * Security hooks for file operations
 *
 * @file_permission:
 *	Check file permissions before accessing an open file.  This hook is
 *	called by various operations that read or write files.  A security
 *	module can use this hook to perform additional checking on these
 *	operations, e.g.  to revalidate permissions on use to support privilege
 *	bracketing or policy changes.  Notice that this hook is used when the
 *	actual read/write operations are performed, whereas the
 *	inode_security_ops hook is called when a file is opened (as well as
 *	many other operations).
 *	Caveat:  Although this hook can be used to revalidate permissions for
 *	various system call operations that read or write files, it does not
 *	address the revalidation of permissions for memory-mapped files.

 *	should never be used by the security module.
 *	Return 0 if permission is granted.

 *	Check permissions for a mmap operation at @addr.
 *	@addr contains virtual address that will be used for the operation.
 *	Return 0 if permission is granted.

 *	never be used by the security module.
 *	@file contains the file structure.
 *	@cmd contains the operation to be performed.
 *	@arg contains the operational arguments.
 *	Return 0 if permission is granted.

 *	Return 0 on success.
 * @file_send_sigiotask:
 *	Check permission for the file owner @fown to send SIGIO or SIGURG to the
 *	process @tsk.  Note that this hook is sometimes called from interrupt.
 *	Note that the fown_struct, @fown, is never outside the context of a
 *	struct file, so the file structure (and associated security information)
 *	can always be obtained: container_of(fown, struct file, f_owner)
 *	@tsk contains the structure of task receiving signal.

 *	length and the next call which actually allocates and returns the
 *	secdata.
 *	@secid contains the security ID.

 *	@ctxlen contains the length of @ctx.
 *
 * @inode_setsecctx:
 *	Change the security context of an inode.  Updates the
 *	incore security context managed by the security module and invokes the
 *	fs code as needed (via __vfs_setxattr_noperm) to update any backing
 *	xattrs that represent the context.  Example usage:  NFS server invokes
 *	this hook to change the security context in its incore inode and on the
 *	backing filesystem to a value provided by the client on a SETATTR
 *	operation.

 *	On success, returns 0 and fills out @ctx and @ctxlen with the security
 *	context for the given @inode.
 *
 *	@inode we wish to get the security context of.
 *	@ctx is a pointer in which to place the allocated security context.
 *	@ctxlen points to the place to put the length of @ctx.
 *
 * Security hooks for using the eBPF maps and programs functionalities through
 * eBPF syscalls.
 *
 * @bpf:
 *	Do a initial check for all bpf syscalls after the attribute is copied
 *	into the kernel. The actual security module can implement their own
 *	rules to check the specific cmd they need.
 *
 * @bpf_map:
 *	Do a check when the kernel generate and return a file descriptor for
 *	eBPF maps.
 *
 *	@map: bpf map that we want to access
 *	@mask: the access flags
