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