https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D235256 --- Comment #9 from commit-hook@freebsd.org --- A commit references this bug: Author: rscheff Date: Thu May 21 19:46:12 UTC 2020 New revision: 361342 URL: https://svnweb.freebsd.org/changeset/base/361342 Log: MFC r360477: Correctly set up the initial TCP congestion window in all ca= ses by not including the SYN bit sequence space in cwnd related calculations. Snd_und is adjusted explicitly in all cases, outside the cwnd update, instead. This fixes an off-by-one conformance issue with regular TCP sessions not using Appropriate Byte Counting (RFC3465), sending one more packet during the initial window than expected.
