134199767f8SToomas Soome /*-
135199767f8SToomas Soome * struct inpcb captures the network layer state for TCP, UDP, and raw IPv4 and
136199767f8SToomas Soome * IPv6 sockets. In the case of TCP and UDP, further per-connection state is
137199767f8SToomas Soome * hung off of inp_ppcb most of the time. Almost all fields of struct inpcb
138199767f8SToomas Soome * are static after creation or protected by a per-inpcb rwlock, inp_lock. A
139199767f8SToomas Soome * few fields are protected by multiple locks as indicated in the locking notes
140199767f8SToomas Soome * below. For these fields, all of the listed locks must be write-locked for
141199767f8SToomas Soome * any modifications. However, these fields can be safely read while any one of
142199767f8SToomas Soome * the listed locks are read-locked. This model can permit greater concurrency
143199767f8SToomas Soome * for read operations. For example, connections can be looked up while only
144199767f8SToomas Soome * holding a read lock on the global pcblist lock. This is important for
145199767f8SToomas Soome * performance when attempting to find the connection for a packet given its IP
146199767f8SToomas Soome * and port tuple.
147199767f8SToomas Soome *
148199767f8SToomas Soome * One noteworthy exception is that the global pcbinfo lock follows a different
149199767f8SToomas Soome * set of rules in relation to the inp_list field. Rather than being
150199767f8SToomas Soome * write-locked for modifications and read-locked for list iterations, it must
151199767f8SToomas Soome * be read-locked during modifications and write-locked during list iterations.
152199767f8SToomas Soome * This ensures that the relatively rare global list iterations safely walk a
153199767f8SToomas Soome * stable snapshot of connections while allowing more common list modifications
154199767f8SToomas Soome * to safely grab the pcblist lock just while adding or removing a connection
155199767f8SToomas Soome * from the global list.
156199767f8SToomas Soome *
157199767f8SToomas Soome * Key:
158199767f8SToomas Soome * (c) - Constant after initialization
159199767f8SToomas Soome * (g) - Protected by the pcbgroup lock
160199767f8SToomas Soome * (i) - Protected by the inpcb lock
161199767f8SToomas Soome * (p) - Protected by the pcbinfo lock for the inpcb
162199767f8SToomas Soome * (l) - Protected by the pcblist lock for the inpcb
163199767f8SToomas Soome * (h) - Protected by the pcbhash lock for the inpcb
164199767f8SToomas Soome * (s) - Protected by another subsystem's locks
165199767f8SToomas Soome * (x) - Undefined locking
166199767f8SToomas Soome *
167199767f8SToomas Soome * A few other notes:
168199767f8SToomas Soome *
169199767f8SToomas Soome * When a read lock is held, stability of the field is guaranteed; to write
170199767f8SToomas Soome * to a field, a write lock must generally be held.
171199767f8SToomas Soome *
172199767f8SToomas Soome * netinet/netinet6-layer code should not assume that the inp_socket pointer
173199767f8SToomas Soome * is safe to dereference without inp_lock being held, even for protocols
174199767f8SToomas Soome * other than TCP (where the inpcb persists during TIMEWAIT even after the
175199767f8SToomas Soome * socket has been freed), or there may be close(2)-related races.
176199767f8SToomas Soome *
177199767f8SToomas Soome * The inp_vflag field is overloaded, and would otherwise ideally be (c).
178199767f8SToomas Soome *
179199767f8SToomas Soome * TODO: Currently only the TCP stack is leveraging the global pcbinfo lock
180199767f8SToomas Soome * read-lock usage during modification, this model can be applied to other
181199767f8SToomas Soome * protocols (especially SCTP).
