| 544 | * Security hooks for file operations |
| 545 | * |
| 546 | * @file_permission: |
| 547 | * Check file permissions before accessing an open file. This hook is |
| 548 | * called by various operations that read or write files. A security |
| 549 | * module can use this hook to perform additional checking on these |
| 550 | * operations, e.g. to revalidate permissions on use to support privilege |
| 551 | * bracketing or policy changes. Notice that this hook is used when the |
| 552 | * actual read/write operations are performed, whereas the |
| 553 | * inode_security_ops hook is called when a file is opened (as well as |
| 554 | * many other operations). |
| 555 | * Caveat: Although this hook can be used to revalidate permissions for |
| 556 | * various system call operations that read or write files, it does not |
| 557 | * address the revalidation of permissions for memory-mapped files. |
| 558 | * Security modules must handle this separately if they need such |
| 559 | * revalidation. |
| 560 | * @file contains the file structure being accessed. |

| 566 | * created. |
| 567 | * @file contains the file structure to secure. |
| 568 | * Return 0 if the hook is successful and permission is granted. |

| 571 | * @file contains the file structure being modified. |

| 576 | * Check permission for an ioctl operation on @file. Note that @arg can |
| 577 | * sometimes represents a user space pointer; in other cases, it may be a |
| 578 | * simple integer value. When @arg represents a user space pointer, it |
| 579 | * should never be used by the security module. |
| 580 | * Return 0 if permission is granted. |
| 581 | * @file_mmap : |
| 582 | * Check permissions for a mmap operation. The @file may be NULL, e.g. |
| 583 | * if mapping anonymous memory. |

| 595 | * @file_lock: |
| 596 | * Check permission before performing file locking operations. |
| 597 | * Note: this hook mediates both flock and fcntl style locks. |
| 598 | * @file contains the file structure. |
| 599 | * @cmd contains the posix-translated lock operation to perform |
| 600 | * (e.g. F_RDLCK, F_WRLCK). |

| 602 | * @file_fcntl: |
| 603 | * Check permission before allowing the file operation specified by @cmd |
| 604 | * from being performed on the file @file. Note that @arg can sometimes |
| 605 | * represents a user space pointer; in other cases, it may be a simple |
| 606 | * integer value. When @arg represents a user space pointer, it should |

| 617 | * @file_send_sigiotask: |

| 619 | * process @tsk. Note that this hook is sometimes called from interrupt. |
| 620 | * Note that the fown_struct, @fown, is never outside the context of a |
