https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D217637 --- Comment #70 from Michael Tuexen <tuexen@freebsd.org> --- (In reply to slw from comment #69) > "Lost" in this context is "not delivered to remote IP stack". > Not application, IP stack. The semantic of an ACK is "delivered to the remote TCP stack. Not received = by the application. But the service is from app to app. In my understanding the TCP should sign= al to the peer if it knows that some data will not be delivered to the app. Th= is signalling is sending an RST. > Remote system ACK data after place in system buffer, not after reading > by application. > I.e. while system can accept data and generate ACK -- all ok. Data delive= red. That is fine by the semantic of an ACK. But my point is that a TCP connection fails if some data can't be delivered= to the application. --=20 You are receiving this mail because: You are the assignee for the bug.=
