# bbrplus-5.10
Linux BBRplus Kernel 5.10 ported from BBRplus 4.14
(note that it does NOT based on 5.10 version of BBR, instead just simple ported the 4.14 version of BBRplus)
***based on original version***
https://github.com/cx9208/bbrplus
## some improvements as Nov-2021
### i) merged official v4.14 tcp_bbr patches between 2018-2021 into bbrplus
### ii) keep official v5.17 tcp_bbr module, so may use either
```sh
net.ipv4.tcp_congestion_control = bbrplus
net.core.default_qdisc = fq
```
or
```sh
net.ipv4.tcp_congestion_control = bbr
net.core.default_qdisc = fq
```
in the `/etc/sysctl.conf` file. ( `fq` is the only recommended packet scheduler, do not use `fq_codel` `fq_pie` `cake` etc )
## patch & build bbrplus kernel youself
(or you can use releases compiled by me in "Releases" section)
***(build requirement to GCC is >= 4.9, so GCC upgrade is needed if use CentOS 7.x as builder)***
### 1) get convert patch on this repository, use git or direct download
(e.g., convert_official_linux-5.10.x_src_to_bbrplus.patch)
### 2) download officaial linux kernel
say 5.10.4
wget https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.10.4.tar.gz
### 3) extract the tarball & cd extracted directory
tar zxvf linux-5.10.4.tar.gz && cd linux-5.10.4
### 4) copy convert patch to extracted kernel directory
something like
cp ../convert_official_linux-5.10.x_src_to_bbrplus.patch .
### 5) do the patch job
patch -p1 < convert_official_linux-5.10.x_src_to_bbrplus.patch
(if no error or failed on previous step)
### 6) install dependencies for building kernels
***CentOS***
sudo yum groupinstall Development tools
sudo yum install ncurses-devel bc gcc gcc-c++ ncurses ncurses-devel cmake elfutils-libelf-devel openssl-devel rpm-build redhat-rpm-config asciidoc hmaccalc perl-ExtUtils-Embed xmlto audit-libs-devel binutils-devel elfutils-devel elfutils-libelf-devel newt-devel python-devel zlib-devel
press "y" key when asked
***Debian/Ubuntu***
sudo apt install build-essential libncurses5-dev
sudo apt build-dep linux
press "y" key when asked
### 7) config build parameters based on current kernel settings
make oldconfig
press Enter key when asked (if dont know what is what)
### 8) disable debug info & module signing
scripts/config --disable DEBUG_INFO && scripts/config --disable MODULE_SIG
### 9) build kernel
***CentOS***
make rpm-pkg LOCALVERSION=-bbrplus 2>&1 | tee build.log
***Debian/Ubuntu***
make deb-pkg LOCALVERSION=-bbrplus 2>&1 | tee build.log
if anything goes wrong check the "build.log" file
(if not failed on previous step)
### 10) collect kernel package files, do test on some other Linux machine
***CentOS files***
located in
/"user home dir"/rpmbuild/RPMS/x86_64/
***Debian/Ubuntu files***
located in
parent directory
