| 567 | * |
| 568 | * @file_permission: |
| 569 | * Check file permissions before accessing an open file. This hook is |
| 570 | * called by various operations that read or write files. A security |
| 571 | * module can use this hook to perform additional checking on these |
| 572 | * operations, e.g. to revalidate permissions on use to support privilege |
| 573 | * bracketing or policy changes. Notice that this hook is used when the |
| 574 | * actual read/write operations are performed, whereas the |
| 575 | * inode_security_ops hook is called when a file is opened (as well as |
| 576 | * many other operations). |
| 577 | * Caveat: Although this hook can be used to revalidate permissions for |
| 578 | * various system call operations that read or write files, it does not |

| 854 | * The @unix_stream_connect and @unix_may_send hooks were necessary because |
| 855 | * Linux provides an alternative to the conventional file name space for Unix |
| 856 | * domain sockets. Whereas binding and connecting to sockets in the file name |
| 857 | * space is mediated by the typical file permissions (and caught by the mknod |
| 858 | * and permission hooks in inode_security_ops), binding and connecting to |
| 859 | * sockets in the abstract name space is completely unmediated. Sufficient |
| 860 | * control of Unix domain sockets in the abstract name space isn't possible |
| 861 | * using only the socket layer hooks, since we need to know the actual target |
| 862 | * socket, which is not looked up until we are inside the af_unix code. |
| 863 | * |
| 864 | * Security hooks for socket operations. |
| 865 | * |

| 873 | * @socket_post_create: |
| 874 | * This hook allows a module to update or allocate a per-socket security |
| 875 | * structure. Note that the security field was not added directly to the |
| 876 | * socket structure, but rather, the socket security information is stored |
| 877 | * in the associated inode. Typically, the inode alloc_security hook will |
| 878 | * allocate and and attach security information to |
| 879 | * sock->inode->i_security. This hook may be used to update the |
| 880 | * sock->inode->i_security field with additional information that wasn't |
