In general, to use these features, a Linux kernel version 4.1 or newer is required. In addition, the kernel should have been compiled with the following flags set:
CONFIG_BPF=y CONFIG_BPF_SYSCALL=y # [optional, for tc filters] CONFIG_NET_CLS_BPF=m # [optional, for tc actions] CONFIG_NET_ACT_BPF=m CONFIG_BPF_JIT=y CONFIG_HAVE_BPF_JIT=y # [optional, for kprobes] CONFIG_BPF_EVENTS=y
Kernel compile flags can usually be checked by looking at /proc/config.gz or /boot/config-<kernel-version>.
Install a 4.3+ kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline, for example:
VER=4.4.2-040402 PREFIX=http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.2-wily/ REL=201602171633 wget ${PREFIX}/linux-headers-${VER}-generic_${VER}.${REL}_amd64.deb wget ${PREFIX}/linux-headers-${VER}_${VER}.${REL}_all.deb wget ${PREFIX}/linux-image-${VER}-generic_${VER}.${REL}_amd64.deb sudo dpkg -i linux-*${VER}.${REL}*.deb # reboot
Update PREFIX to the latest date, and you can browse the files in the PREFIX url to find the REL number.
Tagged and signed bcc binary packages are built for Ubuntu Trusty (14.04) and hosted at http://52.8.15.63/apt/.
To install:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys D4284CDD echo "deb http://52.8.15.63/apt trusty main" | sudo tee /etc/apt/sources.list.d/iovisor.list sudo apt-get update sudo apt-get install libbcc libbcc-examples python-bcc
Test it: sudo python /usr/share/bcc/examples/hello_world.py sudo python /usr/share/bcc/examples/tracing/task_switch.py
(Optional) Install pyroute2 for additional networking features
git clone https://github.com/svinota/pyroute2 cd pyroute2; sudo make install sudo python /usr/share/bcc/examples/simple_tc.py
Install a 4.2+ kernel from http://alt.fedoraproject.org/pub/alt/rawhide-kernel-nodebug, for example:
sudo dnf config-manager --add-repo=http://alt.fedoraproject.org/pub/alt/rawhide-kernel-nodebug/fedora-rawhide-kernel-nodebug.repo sudo dnf update # reboot
Nightly bcc binary packages are built for Fedora 23 and 24, hosted at http://52.8.15.63/yum/nightly/f{23,24}.
To install (change 'f23' to 'f24' for rawhide):
echo -e '[iovisor]\nbaseurl=http://52.8.15.63/yum/nightly/f23/$basearch\nenabled=1\ngpgcheck=0' | sudo tee /etc/yum.repos.d/iovisor.repo sudo dnf install bcc-tools
Upgrade the kernel to minimum 4.3.1-1 first; the CONFIG_BPF_SYSCALL=y configuration was not added until this kernel release.
Install these packages using any AUR helper such as pacaur, yaourt, cower, etc.:
bcc bcc-tools python-bcc python2-bcc
All build and install dependencies are listed in the PKGBUILD and should install automatically.
To build the toolchain from source, one needs:
