| 41 | ---help--- |
| 42 | Support sub policy for developers. By using sub policy with main |
| 43 | one, two policies can be applied to the same packet at once. |
| 44 | Policy which lives shorter time in kernel should be a sub. |

| 52 | A feature to update locator(s) of a given IPsec security |
| 53 | association dynamically. This feature is required, for |
| 54 | instance, in a Mobile IPv6 environment with IPsec configuration |
| 55 | where mobile nodes change their attachment point to the Internet. |

| 90 | Add a PF_KEY MIGRATE message to PF_KEYv2 socket family. |
| 91 | The PF_KEY MIGRATE message is used to dynamically update |
| 92 | locator(s) of a given IPsec security association. |
| 93 | This feature is required, for instance, in a Mobile IPv6 |
| 94 | environment with IPsec configuration where mobile nodes |
| 95 | change their attachment point to the Internet. Detail |
