https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=217637 --- 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 signal to the peer if it knows that some data will not be delivered to the app. This 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 delivered. 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. -- You are receiving this mail because: You are the assignee for the bug.
