| /*- |
| * struct inpcb captures the network layer state for TCP, UDP, and raw IPv4 |
| * and IPv6 sockets. In the case of TCP, further per-connection state is |
| * hung off of inp_ppcb most of the time. Almost all fields of struct inpcb |
| * are static after creation or protected by a per-inpcb rwlock, inp_lock. A |
| * few fields also require the global pcbinfo lock for the inpcb to be held, |
| * when modified, such as the global connection lists and hashes, as well as |
| * binding information (which affects which hash a connection is on). This |
| * model means that connections can be looked up without holding the |
| * per-connection lock, which is important for performance when attempting to |
| * find the connection for a packet given its IP and port tuple. Writing to |
| * these fields that write locks be held on both the inpcb and global locks. |
| * |
| * Key: |
| * (c) - Constant after initialization |
| * (i) - Protected by the inpcb lock |
| * (p) - Protected by the pcbinfo lock for the inpcb |
| * (s) - Protected by another subsystem's locks |
| * (x) - Undefined locking |
| * |
| * A few other notes: |
| * |
| * When a read lock is held, stability of the field is guaranteed; to write |
| * to a field, a write lock must generally be held. |
| * |
| * netinet/netinet6-layer code should not assume that the inp_socket pointer |
| * is safe to dereference without inp_lock being held, even for protocols |
| * other than TCP (where the inpcb persists during TIMEWAIT even after the |
| * socket has been freed), or there may be close(2)-related races. |
| * |
| * The inp_vflag field is overloaded, and would otherwise ideally be (c). |
