| /** |
| * 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 @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. |
| * @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. |
| * Return 0 if permission is granted. |
| * @inode_unlink: |
| * Check the permission to remove a hard link to a file. |
| * @dir contains the inode structure of parent directory of the file. |
| * @dentry contains the dentry structure for file to be unlinked. |
| * Return 0 if permission is granted. |
| * @inode_symlink: |
| * Check the permission to create a symbolic link to a file. |
| * @dir contains the inode structure of parent directory of the symbolic link. |
| * @dentry contains the dentry structure of the symbolic link. |
| * @old_name contains the pathname of file. |
| * Return 0 if permission is granted. |

| * Check permissions to create a new directory in the existing directory |
| * associated with inode strcture @dir. |
| * @dir containst the inode structure of parent of the directory to be created. |
| * @dentry contains the dentry structure of new directory. |
| * @mode contains the mode of new directory. |
| * Return 0 if permission is granted. |
| * @inode_rmdir: |
| * Check the permission to remove a directory. |
| * @dir contains the inode structure of parent of the directory to be removed. |
| * @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. |
| * Return 0 if permission is granted. |
| * @inode_rename: |
| * Check for permission to rename a file or directory. |
| * @old_dir contains the inode structure for parent of the old link. |
| * @old_dentry contains the dentry structure of the old link. |
| * @new_dir contains the inode structure for parent of the new link. |
| * @new_dentry contains the dentry structure of the new link. |
| * Return 0 if permission is granted. |
| * @inode_readlink: |
| * Check the permission to read the symbolic link. |
| * @dentry contains the dentry structure for the file link. |
| * Return 0 if permission is granted. |
| * @inode_follow_link: |
| * Check permission to follow a symbolic link when looking up a pathname. |
| * @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. |
| * @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: |
| * 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. |
| * @mnt is the vfsmount where the dentry was looked up |
| * @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. |
| * @inode_setxattr: |
| * Check permission before setting the extended attributes |
| * @value identified by @name for @dentry. |
| * Return 0 if permission is granted. |

| * Update inode security field after successful setxattr operation. |
| * @value identified by @name for @dentry. |
| * @inode_getxattr: |
| * 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: |
| * Check permission before removing the extended attribute |
| * identified by @name for @dentry. |
| * 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. |
| * The security field is initialized to NULL when the structure is first |
| * created. |
| * @file contains the file structure to secure. |
| * Return 0 if the hook is successful and permission is granted. |
| * @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: |
| * (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. |
| * Return 0 if permission is granted. |
| * @file_receive: |
| * This hook allows security modules to control the ability of a process |
| * to receive an open file descriptor via socket IPC. |
| * @file contains the file structure being received. |
| * Return 0 if permission is granted. |
| * |
| * Security hooks for task operations. |
| * |
| * @task_create: |
| * Check permission before creating a child process. See the clone(2) |
| * manual page for definitions of the @clone_flags. |
| * @clone_flags contains the flags indicating what should be shared. |
| * Return 0 if permission is granted. |
| * @task_alloc_security: |
| * @p contains the task_struct for child process. |
| * Allocate and attach a security structure to the p->security field. The |
| * security field is initialized to NULL when the task structure is |
| * allocated. |
| * Return 0 if operation was successful. |
| * @task_free_security: |
| * @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 |
| * which of the set*uid system calls invoked this hook and how to |
| * 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 |
| * indicates which of the set*uid system calls invoked this hook. If |

| * space is mediated by the typical file permissions (and caught by the mknod |
| * 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. |
