| 549 | * |
| 550 | * @file_permission: |
| 551 | * Check file permissions before accessing an open file. This hook is |
| 552 | * called by various operations that read or write files. A security |
| 553 | * module can use this hook to perform additional checking on these |
| 554 | * operations, e.g. to revalidate permissions on use to support privilege |
| 555 | * bracketing or policy changes. Notice that this hook is used when the |
| 556 | * actual read/write operations are performed, whereas the |
| 557 | * inode_security_ops hook is called when a file is opened (as well as |
| 558 | * many other operations). |
| 559 | * Caveat: Although this hook can be used to revalidate permissions for |
| 560 | * various system call operations that read or write files, it does not |

| 818 | * The @unix_stream_connect and @unix_may_send hooks were necessary because |
| 819 | * Linux provides an alternative to the conventional file name space for Unix |
| 820 | * domain sockets. Whereas binding and connecting to sockets in the file name |
| 821 | * space is mediated by the typical file permissions (and caught by the mknod |
| 822 | * and permission hooks in inode_security_ops), binding and connecting to |
| 823 | * sockets in the abstract name space is completely unmediated. Sufficient |
| 824 | * control of Unix domain sockets in the abstract name space isn't possible |
| 825 | * using only the socket layer hooks, since we need to know the actual target |
| 826 | * socket, which is not looked up until we are inside the af_unix code. |

| 828 | * Security hooks for socket operations. |
| 829 | * |
| 830 | * @socket_create: |
| 831 | * Check permissions prior to creating a new socket. |
| 832 | * @family contains the requested protocol family. |
| 833 | * @type contains the requested communications type. |
| 834 | * @protocol contains the requested protocol. |
| 835 | * @kern set to 1 if a kernel socket. |
| 836 | * Return 0 if permission is granted. |
| 837 | * @socket_post_create: |
| 838 | * This hook allows a module to update or allocate a per-socket security |
| 839 | * structure. Note that the security field was not added directly to the |
| 840 | * socket structure, but rather, the socket security information is stored |
| 841 | * in the associated inode. Typically, the inode alloc_security hook will |
| 842 | * allocate and and attach security information to |
| 843 | * sock->inode->i_security. This hook may be used to update the |
| 844 | * sock->inode->i_security field with additional information that wasn't |
| 845 | * available when the inode was allocated. |
| 846 | * @sock contains the newly created socket structure. |
| 847 | * @family contains the requested protocol family. |
| 848 | * @type contains the requested communications type. |
| 849 | * @protocol contains the requested protocol. |
| 850 | * @kern set to 1 if a kernel socket. |
| 851 | * @socket_bind: |
| 852 | * Check permission before socket protocol layer bind operation is |
| 853 | * performed and the socket @sock is bound to the address specified in the |
| 854 | * @address parameter. |
| 855 | * @sock contains the socket structure. |
| 856 | * @address contains the address to bind to. |
| 857 | * @addrlen contains the length of address. |
