- * 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).
