https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=234444 --- Comment #8 from Michael Tuexen <tuexen@freebsd.org> --- (In reply to Sergey Samoyloff from comment #6) Here is the config I'm using when trying to reproduce it: tuexen@stable11:~ % uname -a FreeBSD stable11 11.2-RELEASE-p8 FreeBSD 11.2-RELEASE-p8 #0 r342950: Fri Jan 11 23:37:10 CET 2019 tuexen@stable11:/usr/home/tuexen/releng/11.2/sys/amd64/compile/TCP amd64 tuexen@stable11:~ % sysctl net.inet.tcp.cc.algorithm net.inet.tcp.cc.algorithm: htcp tuexen@stable11:~ % sysctl net.inet.tcp.cc.htcp net.inet.tcp.cc.htcp.rtt_scaling: 1 net.inet.tcp.cc.htcp.adaptive_backoff: 1 tuexen@stable11:~ % sysctl net.inet.tcp.fastopen.enabled net.inet.tcp.fastopen.enabled: 1 tuexen@stable11:~ % cat stable/11/sys/amd64/conf/TCP include GENERIC ident TCP makeoptions WITH_EXTRA_TCP_STACKS=1 options TCP_RFC7413 options IPFIREWALL options IPFIREWALL_VERBOSE options IPFIREWALL_VERBOSE_LIMIT=5 options IPFIREWALL_DEFAULT_TO_ACCEPT tuexen@stable11:~ % cat /etc/make.conf MODULES_OVERRIDE=tcp cc opensolaris dtrace I have a HTTP server supporting TCP fast open running and an sshd not using TCP fast open. I can log into the machine without problems, and access the HTTP server actually using TCP fast open. So the problem is not just using a combination of the CC module and using TCP fast open. Just to double check: When you compiled you custom kernel with TCP fast open enabled, you also recompiled the kernel modules you are using, right? -- You are receiving this mail because: You are the assignee for the bug.
