119 * struct inpcb captures the network layer state for TCP, UDP, and raw IPv4
120 * and IPv6 sockets. In the case of TCP, further per-connection state is
121 * hung off of inp_ppcb most of the time. Almost all fields of struct inpcb
122 * are static after creation or protected by a per-inpcb rwlock, inp_lock. A
123 * few fields also require the global pcbinfo lock for the inpcb to be held,
124 * when modified, such as the global connection lists and hashes, as well as
125 * binding information (which affects which hash a connection is on). This
126 * model means that connections can be looked up without holding the
127 * per-connection lock, which is important for performance when attempting to
128 * find the connection for a packet given its IP and port tuple. Writing to
129 * these fields that write locks be held on both the inpcb and global locks.
130 *
131 * Key:
132 * (c) - Constant after initialization
133 * (i) - Protected by the inpcb lock
134 * (p) - Protected by the pcbinfo lock for the inpcb
135 * (s) - Protected by another subsystem's locks
136 * (x) - Undefined locking
137 *
138 * A few other notes:
139 *
140 * When a read lock is held, stability of the field is guaranteed; to write
141 * to a field, a write lock must generally be held.
142 *
143 * netinet/netinet6-layer code should not assume that the inp_socket pointer
144 * is safe to dereference without inp_lock being held, even for protocols
145 * other than TCP (where the inpcb persists during TIMEWAIT even after the
146 * socket has been freed), or there may be close(2)-related races.
147 *
148 * The inp_vflag field is overloaded, and would otherwise ideally be (c).
