-/**
- * struct security_operations - main security structure
- *
- * Security module identifier.
- *
- * @name:
- * A string that acts as a unique identifeir for the LSM with max number
- * of characters = SECURITY_NAME_MAX.
- *
- * 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 @mnt
- * mountpoint.
- * @dentry is a handle on the superblock 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.
- * @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_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.
- * @path contains the path 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_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 contains the path for the mount point.
- * @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_post_pivotroot:
- * Update module state after a successful pivot.
- * @old_path contains the path for the old root.
- * @new_path contains the path for the new root.
- * @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
- *
- * 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.

- * 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.

- * @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.

- * other operations), whereas the file_security_ops permission hook is
- * called when the actual read/write operations are performed.
- * @inode contains the inode structure to check.
- * @mask contains the permission mask.
- * @nd contains the nameidata (may be NULL).
- * Return 0 if permission is granted.
- * @inode_setattr:

- * @inode_delete:
- * @inode contains the inode structure for deleted inode.
- * This hook is called when a deleted inode is released (i.e. an inode

- * security label associated with @name for @inode via @buffer. Note that
- * @name is the remainder of the attribute name after the security prefix
- * has been removed. @alloc is used to specify of the call should return a
- * value via the buffer or just the value length Return size of buffer 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

- * 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

- * Called when an inode has been changed.
- * @dentry is the dentry being changed.

- * @inode_killpriv:
- * The setuid bit is being removed. Remove similar security labels.
- * Called with the dentry->d_inode->i_mutex held.

- * In case of failure, @secid will be set to zero.
- *
- * 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:

- * @file_free_security:
- * Deallocate and free any security structures stored in file->f_security.
- * @file contains the file structure being modified.
- * @file_ioctl:
- * @file contains the file structure.
- * @cmd contains the operation to perform.
- * @arg contains the operational arguments.
- * 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.
- * @flags contains the operational flags.
- * Return 0 if permission is granted.
- * @file_mprotect:
- * Check permissions before changing memory access permissions.
- * @vma contains the memory region to modify.
- * @reqprot contains the protection requested by the application.
- * @prot contains the protection that will be applied by the kernel.
- * Return 0 if permission is granted.
- * @file_lock:
- * Check permission before performing file locking operations.
- * Note: this hook mediates both flock and fcntl style locks.
- * @file contains the file structure.
- * @cmd contains the posix-translated lock operation to perform
- * (e.g. F_RDLCK, F_WRLCK).
- * Return 0 if permission is granted.
- * @file_fcntl:
- * Check permission before allowing the file operation specified by @cmd
- * from being performed on the file @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.
- * @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:
- * Save owner security information (typically from current->security) in
- * 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:
- * container_of(fown, 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.
- * Return 0 if permission is granted.

- *
- * @task_create:
- * Check permission before creating a child process. See the clone(2)
- * manual page for definitions of the @clone_flags.

- * @capset_check:
- * Check permission before setting the @effective, @inheritable, and
- * @permitted capability sets for the @target process.
- * Caveat: @target is also set to current if a set of processes is
- * specified (i.e. all processes other than current and init or a
- * particular process group). Hence, the capset_set hook may need to
- * revalidate permission to the actual target process.
- * @target contains the task_struct structure for target process.
- * @effective contains the effective capability set.
- * @inheritable contains the inheritable capability set.
- * @permitted contains the permitted capability set.
- * Return 0 if permission is granted.
- * @capset_set:
- * Set the @effective, @inheritable, and @permitted capability sets for
- * the @target process. Since capset_check cannot always check permission
- * to the real @target process, this hook may also perform permission
- * checking to determine if the current process is allowed to set the
- * capability sets of the @target process. However, this hook has no way
- * of returning an error due to the structure of the sys_capset code.
- * @target contains the task_struct structure for target process.
- * @effective contains the effective capability set.
- * @inheritable contains the inheritable capability set.
- * @permitted contains the permitted capability set.
- * @capable:
- * Check whether the @tsk process has the @cap capability.
- * @tsk contains the task_struct for the process.
- * @cap contains the capability <include/linux/capability.h>.
- * Return 0 if the capability is granted for @tsk.
- * @acct:
- * Check permission before enabling or disabling process accounting. If
- * accounting is being enabled, then @file refers to the open file used to
- * store accounting records. If accounting is being disabled, then @file
- * is NULL.
- * @file contains the file structure for the accounting file (may be NULL).
- * Return 0 if permission is granted.
- * @sysctl:
- * Check permission before accessing the @table sysctl variable in the
- * manner specified by @op.
- * @table contains the ctl_table structure for the sysctl variable.
- * @op contains the operation (001 = search, 002 = write, 004 = read).
- * Return 0 if permission is granted.
- * @syslog:
- * Check permission before accessing the kernel message ring or changing
- * logging to the console.
- * See the syslog(2) manual page for an explanation of the @type values.
- * @type contains the type of action.
- * Return 0 if permission is granted.
- * @settime:
- * Check permission to change the system time.
- * struct timespec and timezone are defined in include/linux/time.h
- * @ts contains new time
- * @tz contains new timezone
- * Return 0 if permission is granted.
- * @vm_enough_memory:
- * Check permissions for allocating a new virtual mapping.
- * @mm contains the mm struct it is being added to.
- * @pages contains the number of pages.
- * Return 0 if permission is granted.
- *
- * @secid_to_secctx:
- * Convert secid to security context.
- * @secid contains the security ID.
- * @secdata contains the pointer that stores the converted security context.
- * @secctx_to_secid:
- * Convert security context to secid.
- * @secid contains the pointer to the generated security ID.
- * @secdata contains the security context.
- *
- * @release_secctx:
- * Release the security context.
- * @secdata contains the security context.
- * @seclen contains the length of the security context.
- *
- * Security hooks for Audit
- *
- * @audit_rule_init:
- * Allocate and initialize an LSM audit rule structure.
- * @field contains the required Audit action. Fields flags are defined in include/linux/audit.h
- * @op contains the operator the rule uses.
- * @rulestr contains the context where the rule will be applied to.
- * @lsmrule contains a pointer to receive the result.
- * Return 0 if @lsmrule has been successfully set,
- * -EINVAL in case of an invalid rule.
- *
- * @audit_rule_known:
- * Specifies whether given @rule contains any fields related to current LSM.
- * @rule contains the audit rule of interest.
- * Return 1 in case of relation found, 0 otherwise.
- *
- * @audit_rule_match:
- * Determine if given @secid matches a rule previously approved
- * by @audit_rule_known.
- * @secid contains the security id in question.
- * @field contains the field which relates to current LSM.
- * @op contains the operator that will be used for matching.
- * @rule points to the audit rule that will be checked against.
- * @actx points to the audit context associated with the check.
- * Return 1 if secid matches the rule, 0 if it does not, -ERRNO on failure.
- *
- * @audit_rule_free:
- * Deallocate the LSM audit rule structure previously allocated by
- * audit_rule_init.
- * @rule contains the allocated rule
- *
- * This is the main security structure.
