Fri 01 Oct 2021 06:24:56 PM UTC, comment #8: That commit did not fix this bug. To be completely honest, I don't know any more why it references this bug. As to backporting it, this is one of the commits I don't feel certain enough about to add it to a stable/bugfix only release. |

Tue 04 Jun 2019 07:07:02 PM UTC, comment #2: Hmm, can you reproduce this? If so, could you just add more output? e.g. the values of rcv_wnd and TCP_TCPLEN(cseg). Maybe it's an off-by-one (due to SYN/FIN) or some kind of overflow? |
