--- Comment #6 from Michael Tuexen <tue...@freebsd.org> --- (In reply to Roman Bogorodskiy from comment #5) Hi Roman, I introduced a regression, which was fixed in https://cgit.FreeBSD.org/src/commit/?id=cc3c34859eab1b317d0f38731355b53f7d978c97 and MFCed to stable/12 in https://cgit.FreeBSD.org/src/commit/?id=d05d908d6d3c85479c84c707f931148439ae826b. This was affecting the handling of received TCP RST segments. Does this fix your issue? In bug #252449 it was reported that there are broken TCP stacks, which negotiate TCP timestamp support but then don't behave as required. To deal with such broken implementations I added a sysctl variable in https://cgit.FreeBSD.org/src/commit/?id=d2b3ceddccac60b563f642898e3a314647666a10 , which was MFCed to stable/12 in https://cgit.FreeBSD.org/src/commit/?id=e82353f84c58da9a5c38bd471a09936c16a5b6ea. In this case you can set the sysctl variable net.inet.tcp.tolerate_missing_ts to 1. I would be interested to now which stack is broken and it would be great if you could provide a .pcap file of the failing TCP connection. Does this fix your issue? -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
