My first thoughts on this topic were about to extent tcp(4) and create links to tcp_rack(4) and tcp_bbr(4), but separate manpages maybe the way to go. I just have to investigate the respective details. I was once very deep into TCP/IP, while building perimeter firewalls with FreeBSD, but this was 20 years ago. I add you as a reviever for the differential once I have a rough cut for the manpages ready. Best regards, Gordon > >> Am 09.05.2020 um 14:37 schrieb Michael Tuexen : > >>> On 9.

Re: Error loading tcp_bbr kernel module
Hi Michael, with a kernel config which includes include GENERIC options RATELIMIT options TCPHPTS applied, I could successfully use net.inet.tcp.functions_default=bbr to switch the TCP stack.

Re: Error loading tcp_bbr kernel module
Hi Michael, thanks for your reply. I tried tcp_rack and tcp_bbr, since both are separate TCP stacks. I just posted the wrong error message. Both TCP stacks weren’t loadable as a kernel module with just the former mentioned build option. I currently have build running with both kernel options you mentioned. If the build is successful and I can change the default TCP stack to RACK and BBR I let you know. Further I didn’t find any documentation within tcp(4) regarding RACK and BBR. Since I am about to enhance the manpages, I’ll extent tcp(4) about information about RACK and BBR, but this is a different topic.

Error loading tcp_bbr kernel module
Greetings, I build -CURRENT with WITH_EXTRA_TCP_STACKS=1, but I got the following error when I try to load for example tcp_bbr.ko. kldload: an error occurred while loading module tcp_rack.ko. Please check dmesg(8) for more details. dmesg shows: KLD tcp_bbr.ko: depends on tcphpts - not available or version mismatch linker_load_file: /boot/kernel/tcp_bbr.ko - unsupported file type Any hints on solving the problem? The kernel config is GENERIC.

I'd probably create a custom kernel config that amounted to: include GENERIC options TCPHPTS Peace, david -- David H.
