Modified files:
sys/kern uipc_socket2.c
sys/netinet tcp_input.c
sys/sys socketvar.h
Log:
Introduce sbreserve_locked(), which asserts the socket buffer lock on
the socket buffer having its limits adjusted. sbreserve() now acquires
the lock before calling sbreserve_locked(). In soreserve(), acquire
socket buffer locks across read-modify-writes of socket buffer fields,
and calls into sbreserve/sbrelease; make sure to acquire in keeping
with the socket buffer lock order. In tcp_mss(), acquire the socket
buffer lock in the calling context so that we have atomic read-modify
-write on buffer sizes.
