sys/kern : uipc_socket.c
Log message:
Use read once in socket filter functions.
The socket filt_...() functions are called with shared netlock, but
without per socket lock. This can be done as they are read-only.
After unlocking, TCP will modify socket variables in parallel. So
explicitly mark with READ_ONCE() where unlocked access to socket
fields happens.
OK mvs@
