tcp_available_congestion_control add htcp and bbr

Hi John,

I've updated kernel build as per your request, and I have these files. Please do "apt update" and "apt upgrade", then your kernel will be updated.

$ ls kernel/net/ipv4/tcp_*
kernel/net/ipv4/tcp_bbr.ko kernel/net/ipv4/tcp_htcp.ko kernel/net/ipv4/tcp_vegas.ko
kernel/net/ipv4/tcp_bic.ko kernel/net/ipv4/tcp_hybla.ko kernel/net/ipv4/tcp_veno.ko
kernel/net/ipv4/tcp_cdg.ko kernel/net/ipv4/tcp_illinois.ko kernel/net/ipv4/tcp_westwood.ko
kernel/net/ipv4/tcp_dctcp.ko kernel/net/ipv4/tcp_lp.ko kernel/net/ipv4/tcp_yeah.ko
kernel/net/ipv4/tcp_diag.ko kernel/net/ipv4/tcp_nv.ko
kernel/net/ipv4/tcp_highspeed.ko kernel/net/ipv4/tcp_scalable.ko

Thanks.
Dongjin.

hi Donglin,

cool — thanks. but it seems i am getting errors when i try to add and then update from your ppa (see output below). it looks like apt-get update && apt-get upgrade are not able to pull down updates to your rc4 or your rc5 spin….

suggestions?

thanks,

john

Hi John,

From the log, I am seeing that your C2 is installed with my Debian installer. Right? It already has all repository information, so you don't need to run the command "add-apt-repository ppa:tobetter/ppa" which adds another repository for Ubuntu 'cosmic' distribution which I don't be kernel image for.

So my suggestion is that go to /etc/apt/sources.list.d and remove a file which has "http://ppa.launchpad.net/tobetter/ppa/ubuntu cosmic" and do "apt update" for sure that no error happens.

In order to install new build, I have another package 'linux-image-upstream-odroid' which will install upstream kernel. Simply, just make sure you do not have an error with "apt update" and run "apt install linux-image-upstream-odroid". This will install "v4.17-rc5" from my Launchpad.

Please let me know if it works for you.

Cheers!!

hi Dongjin,

yes: sorry, my bad…

i followed your suggestions to remove the extraneous file in /etc/apt/sources.list.d and apt update then completed without error.

i installed linux-image-upstream-odroid and the system was then able to update / install to v4.17-rc5.

thanks much…

john

Hi John,

No worries... :)
FYI, even though you have installed 'linux-image-upstream-odroid', it won't update recent kernel image all the time. Because I have to update the package with test Linux image. In that case and you'd like to install updated image, you should download *.deb and install it with the command 'dpkg'. :)

Thanks,
Dongjin.
