/**
 * struct security_operations - main security structure
 *
 * Security hooks for program execution operations.
 *
 * @bprm_alloc_security:
 *	Allocate and attach a security structure to the @bprm->security field.
 *	The security field is initialized to NULL when the bprm structure is
 *	allocated.
 *	@bprm contains the linux_binprm structure to be modified.
 *	Return 0 if operation was successful.
 * @bprm_free_security:
 *	@bprm contains the linux_binprm structure to be modified.
 *	Deallocate and clear the @bprm->security field.
 * @bprm_apply_creds:
 *	Compute and set the security attributes of a process being transformed
 *	by an execve operation based on the old attributes (current->security)
 *	and the information saved in @bprm->security by the set_security hook.
 *	Since this hook function (and its caller) are void, this hook can not
 *	return an error.  However, it can leave the security attributes of the
 *	process unchanged if an access failure occurs at this point.
 *	bprm_apply_creds is called under task_lock.  @unsafe indicates various
 *	reasons why it may be unsafe to change security state.
 *	@bprm contains the linux_binprm structure.
 * @bprm_post_apply_creds:
 *	Runs after bprm_apply_creds with the task_lock dropped, so that
 *	functions which cannot be called safely under the task_lock can
 *	be used.  This hook is a good place to perform state changes on
 *	the process such as closing open file descriptors to which access
 *	is no longer granted if the attributes were changed.
 *	Note that a security module might need to save state between
 *	bprm_apply_creds and bprm_post_apply_creds to store the decision
 *	on whether the process may proceed.
 *	@bprm contains the linux_binprm structure.
 * @bprm_set_security:
 *	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.
 *	@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_security call.  The primary difference from
 * 	set_security 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_security is called
 * 	first.
 * 	@bprm contains the linux_binprm structure.
 *	Return 0 if the hook is successful and permission is granted.
 * @bprm_secureexec:
 *      Return a boolean value (0 or 1) indicating whether a "secure exec" 
 *      is required.  The flag is passed in the auxiliary table
 *      on the initial stack to the ELF interpreter to indicate whether libc 
 *      should enable secure mode.
 *      @bprm contains the linux_binprm structure.
 *
 * 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 @sb
 *	filesystem.
 *	@sb contains the super_block structure for the filesystem.
 *	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.
 *	@nd contains the nameidata structure 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_check_sb:
 *	Check permission before the device with superblock @mnt->sb is mounted
 *	on the mount point named by @nd.
 *	@mnt contains the vfsmount for device being mounted.
 *	@nd contains the nameidata object for the mount point.
 *	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_umount_close:
 *	Close any files in the @mnt mounted filesystem that are held open by
 *	the security module.  This hook is called during an umount operation
 *	prior to checking whether the filesystem is still busy.
 *	@mnt contains the mounted filesystem.
 * @sb_umount_busy:
 *	Handle a failed umount of the @mnt mounted filesystem, e.g.  re-opening
 *	any files that were closed by umount_close.  This hook is called during
 *	an umount operation if the umount fails after a call to the
 *	umount_close hook.
 *	@mnt contains the mounted filesystem.
 * @sb_post_remount:
 *	Update the security module's state when a filesystem is remounted.
 *	This hook is only called if the remount was successful.
 *	@mnt contains the mounted file system.
 *	@flags contains the new filesystem flags.
 *	@data contains the filesystem-specific data.
 * @sb_post_mountroot:
 *	Update the security module's state when the root filesystem is mounted.
 *	This hook is only called if the mount was successful.
 * @sb_post_addmount:
 *	Update the security module's state when a filesystem is mounted.
 *	This hook is called any time a mount is successfully grafetd to
 *	the tree.
 *	@mnt contains the mounted filesystem.
 *	@mountpoint_nd contains the nameidata structure for the mount point.
 * @sb_pivotroot:
 *	Check permission before pivoting the root filesystem.
 *	@old_nd contains the nameidata structure for the new location of the current root (put_old).
 *      @new_nd contains the nameidata structure for the new root (new_root).
 *	Return 0 if permission is granted.
 * @sb_post_pivotroot:
 *	Update module state after a successful pivot.
 *	@old_nd contains the nameidata structure for the old root.
 *      @new_nd contains the nameidata structure for the new root.
 *
 * 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.
 *	@name will be set to the allocated name suffix (e.g. selinux).
 *	@value will be set to the allocated attribute value.
 *	@len will be set to the length of the value.
 *	Returns 0 if @name and @value have been successfully set,
 *		-EOPNOTSUPP if no security attribute is needed, or
 *		-ENOMEM on memory allocation failure.
 * @inode_create:
 *	Check permission to create a regular file.
 *	@dir contains inode structure of the parent of the new file.
 *	@dentry contains the dentry structure for the file to be created.
 *	@mode contains the file mode of the file to be created.
 *	Return 0 if permission is granted.
 * @inode_link:
 *	Check permission before creating a new hard link to a file.
 *	@old_dentry contains the dentry structure for an existing link to the file.
 *	@dir contains the inode structure of the parent directory of the new link.
 *	@new_dentry contains the dentry structure for the new link.

 *	@dentry contains the dentry structure of directory to be removed.
 *	Return 0 if permission is granted.
 * @inode_mknod:
 *	Check permissions when creating a special file (or a socket or a fifo
 *	file created via the mknod system call).  Note that if mknod operation
 *	is being done for a regular file, then the create hook will be called
 *	and not this hook.
 *	@dir contains the inode structure of parent of the new file.
 *	@dentry contains the dentry structure of the new file.
 *	@mode contains the mode of the new file.
 *	@dev contains the the device number.

 *	@dentry contains the dentry structure for the link.
 *	@nd contains the nameidata structure for the parent directory.
 *	Return 0 if permission is granted.
 * @inode_permission:
 *	Check permission before accessing an inode.  This hook is called by the
 *	existing Linux permission function, so a security module can use it to
 *	provide additional checking for existing Linux permission checks.
 *	Notice that this hook is called when a file is opened (as well as many
 *	other operations), whereas the file_security_ops permission hook is
 *	called when the actual read/write operations are performed.

 *	@mask contains the permission mask.
 *     @nd contains the nameidata (may be NULL).
 *	Return 0 if permission is granted.
 * @inode_setattr:
 *	Check permission before setting file attributes.  Note that the kernel
 *	call to notify_change is performed from several locations, whenever
 *	file attributes change (such as when a file is truncated, chown/chmod
 *	operations, transferring disk quotas, etc).
 *	@dentry contains the dentry structure for the file.
 *	@attr is the iattr structure containing the new file attributes.
 *	Return 0 if permission is granted.
 * @inode_getattr:
 *	Check permission before obtaining file attributes.

 *	@dentry contains the dentry structure for the file.
 *	Return 0 if permission is granted.
 * @inode_delete:
 *	@inode contains the inode structure for deleted inode.
 *	This hook is called when a deleted inode is released (i.e. an inode
 *	with no hard links has its use count drop to zero).  A security module
 *	can use this hook to release any persistent label associated with the
 *	inode.

 * 	Check permission before obtaining the extended attributes
 * 	identified by @name for @dentry.
 * 	Return 0 if permission is granted.
 * @inode_listxattr:
 * 	Check permission before obtaining the list of extended attribute 
 * 	names for @dentry.
 * 	Return 0 if permission is granted.
 * @inode_removexattr:

 * 	Return 0 if permission is granted.
 * @inode_getsecurity:
 *	Copy the extended attribute representation of the security label 
 *	associated with @name for @inode into @buffer.  @buffer may be
 *	NULL to request the size of the buffer required.  @size indicates
 *	the size of @buffer in bytes.  Note that @name is the remainder
 *	of the attribute name after the security. prefix has been removed.
 *	@err is the return value from the preceding fs getxattr call,
 *	and can be used by the security module to determine whether it
 *	should try and canonicalize the attribute value.
 *	Return number of bytes used/required on success.
 * @inode_setsecurity:
 *	Set the security label associated with @name for @inode from the
 *	extended attribute value @value.  @size indicates the size of the
 *	@value in bytes.  @flags may be XATTR_CREATE, XATTR_REPLACE, or 0.
 *	Note that @name is the remainder of the attribute name after the 
 *	security. prefix has been removed.
 *	Return 0 on success.
 * @inode_listsecurity:
 *	Copy the extended attribute names for the security labels
 *	associated with @inode into @buffer.  The maximum size of @buffer
 *	is specified by @buffer_size.  @buffer may be NULL to request
 *	the size of the buffer required.
 *	Returns number of bytes used/required on success.
 *
 * 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.
 *	Security modules must handle this separately if they need such
 *	revalidation.
 *	@file contains the file structure being accessed.
 *	@mask contains the requested permissions.
 *	Return 0 if permission is granted.
 * @file_alloc_security:
 *	Allocate and attach a security structure to the file->f_security field.

 *	Check permission for an ioctl operation on @file.  Note that @arg can
 *	sometimes represents a user space pointer; in other cases, it may be a
 *	simple integer value.  When @arg represents a user space pointer, it
 *	should never be used by the security module.
 *	Return 0 if permission is granted.
 * @file_mmap :
 *	Check permissions for a mmap operation.  The @file may be NULL, e.g.
 *	if mapping anonymous memory.
 *	@file contains the file structure for file to map (may be NULL).
 *	@reqprot contains the protection requested by the application.
 *	@prot contains the protection that will be applied by the kernel.

 *	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.
 * @file_set_fowner:

 *	file->f_security for later use by the send_sigiotask hook.
 *	@file contains the file structure to update.
 *	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:
 *		(struct file *)((long)fown - offsetof(struct file,f_owner));
 * 	@tsk contains the structure of task receiving signal.
 *	@fown contains the file owner information.
 *	@sig is the signal that will be sent.  When 0, kernel sends SIGIO.

 *	@p contains the task_struct for process.
 *	Deallocate and clear the p->security field.
 * @task_setuid:
 *	Check permission before setting one or more of the user identity
 *	attributes of the current process.  The @flags parameter indicates

 *	interpret the @id0, @id1, and @id2 parameters.  See the LSM_SETID
 *	definitions at the beginning of this file for the @flags values and
 *	their meanings.
 *	@id0 contains a uid.
 *	@id1 contains a uid.
 *	@id2 contains a uid.
 *	@flags contains one of the LSM_SETID_* values.
 *	Return 0 if permission is granted.
 * @task_post_setuid:
 *	Update the module's state after setting one or more of the user
 *	identity attributes of the current process.  The @flags parameter

 *	@p contains the task_struct for process being modified.
 *	@pgid contains the new pgid.
 *	Return 0 if permission is granted.
 * @task_getpgid:
 *	Check permission before getting the process group identifier of the
 *	process @p.
 *	@p contains the task_struct for the process.
 *	Return 0 if permission is granted.

 * and permission hooks in inode_security_ops), binding and connecting to
 * sockets in the abstract name space is completely unmediated.  Sufficient
 * control of Unix domain sockets in the abstract name space isn't possible
 * using only the socket layer hooks, since we need to know the actual target
 * socket, which is not looked up until we are inside the af_unix code.
