Modified Files: src/sys/netinet: tcp_input.c Log Message: Fix fast path for uni directional transfers pure ACK case: drag snd_wl2 along so only newer ACKs can update the window size. also avoids the state where snd_wl2 is eventually larger than th_ack and thus blocking the window update mechanism and the connection gets stuck for a loooong time in the zero sized send window state. see PR/kern 55567 ok thorpej@, also found in FreeBSD To generate a diff of this commit: cvs rdiff -u -r1.418 -r1.419 src/sys/netinet/tcp_input.c Please note that diffs are not public domain; they are subject to the copyright notices on the relevant files.
