Re: [itojun@iijlab.net: accept(2) behavior with tcp RST right after handshake]

[Barney Wolff]

The graceful-close debate is a very old one, going back more than
twenty years.  X.25 and ISO-TP have non-graceful close - the close
can pass data in the network and cause it to be lost.  TCP is
defined as graceful-close.  In SVR4 TLI there are two types of
stream "sockets" with graceful or ugly close semantics.

Having said all that, I certainly agree with Wietse that the POLA
demands that a PF-LOCAL stream socket behave like TCP.
