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
# [for Linux kernel versions 4.1 through 4.6]
CONFIG_HAVE_BPF_JIT=y
# [for Linux kernel versions 4.7 and later]
CONFIG_HAVE_EBPF_JIT=y
# [optional, for kprobes]
CONFIG_BPF_EVENTS=y
There are a few optional kernel flags needed for running bcc networking examples on vanilla kernel:
CONFIG_NET_SCH_SFQ=m
CONFIG_NET_ACT_POLICE=m
CONFIG_NET_ACT_GACT=m
CONFIG_DUMMY=m
CONFIG_VXLAN=m
Kernel compile flags can usually be checked by looking at /proc/config.gz or
/boot/config-<kernel-version>.
bcc and its tools are available in the standard Debian main repository, from the source package bpfcc under the names bpfcc-tools, python-bpfcc, libbpfcc and libbpfcc-dev.
Versions of bcc are available in the standard Ubuntu
Universe repository, as well in iovisor's PPA. The Ubuntu packages have slightly different names: where iovisor
packages use bcc in the name (e.g. bcc-tools), Ubuntu packages use bpfcc (e.g.
bpfcc-tools).
Currently, BCC packages for both the Ubuntu Universe, and the iovisor builds are outdated. This is a known and tracked in:
- Universe - Ubuntu Launchpad
- iovisor - BCC GitHub Issues Currently, building from source is currently the only way to get up to date packaged version of bcc.
Ubuntu Packages Source packages and the binary packages produced from them can be found at packages.ubuntu.com.
sudo apt-get install bpfcc-tools linux-headers-$(uname -r)The tools are installed in /sbin (/usr/sbin in Ubuntu 18.04) with a -bpfcc extension. Try running sudo opensnoop-bpfcc.
Note: the Ubuntu packages have different names but the package contents, in most cases, conflict and as such cannot be installed alongside upstream packages. Should one choose to use Ubuntu's packages instead of the upstream iovisor packages (or vice-versa), the conflicting packages will need to be removed.
The iovisor packages do declare they provide the Ubuntu packages and as such may be
used to satisfy dependencies. For example, should one attempt to install package foo
which declares a dependency on libbpfcc while the upstream libbcc package is installed,
foo should install without trouble as libbcc declares that it provides libbpfcc.
That said, one should always test such a configuration in case of version incompatibilities.

As of Fedora 30, bcc binaries are available in the standard repository. You can install them via
sudo dnf install bccNote: if you keep getting Failed to load program: Operation not permitted when
trying to run the hello_world.py example as root then you might need to lift
the so-called kernel lockdown (cf.
FAQ,
background article).
Ensure that you are running a 4.2+ kernel with uname -r. If not, 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

sudo dnf install bcc-tools kernel-devel-$(uname -r) kernel-headers-$(uname -r)bcc is available in the standard Arch repos, so it can be installed with the pacman command:
# pacman -S bcc bcc-tools python-bcc
First of all, upgrade the kernel of your choice to a recent version. For example:
emerge sys-kernel/gentoo-sources
Then, configure the kernel enabling the features you need. Please consider the following as a starting point:
CONFIG_BPF=y
CONFIG_BPF_SYSCALL=y
CONFIG_NET_CLS_BPF=m
CONFIG_NET_ACT_BPF=m
CONFIG_BPF_JIT=y
CONFIG_BPF_EVENTS=y
Finally, you can install bcc with:
emerge dev-util/bcc
The appropriate dependencies (e.g., clang, llvm with BPF backend) will be pulled automatically.
For openSUSE Leap 42.2 (and later) and Tumbleweed, bcc is already included in the official repo. Just install the packages with zypper.
sudo zypper ref
sudo zypper in bcc-tools bcc-examplesFor RHEL 7.6, bcc is already included in the official yum repository as bcc-tools. As part of the install, the following dependencies are installed: bcc.x86_64 0:0.6.1-2.el7 ,llvm-private.x86_64 0:6.0.1-2.el7 ,python-bcc.x86_64 0:0.6.1-2.el7,python-netaddr.noarch 0:0.7.5-9.el7
yum install bcc-tools
Use case 1. Install BCC for latest kernel available in repo: Tested on Amazon Linux AMI release 2018.03 (kernel 4.14.88-72.73.amzn1.x86_64)
sudo yum update kernel
sudo yum install bcc
sudo reboot
Use case 2. Install BCC for your AMI's default kernel (no reboot required): Tested on Amazon Linux AMI release 2018.03 (kernel 4.14.77-70.59.amzn1.x86_64)
sudo yum install kernel-headers-$(uname -r | cut -d'.' -f1-5)
sudo yum install kernel-devel-$(uname -r | cut -d'.' -f1-5)
sudo yum install bcc
Use case 1. Install BCC for your AMI's default kernel (no reboot required): Tested on Amazon Linux AMI release 2020.03 (kernel 4.14.154-128.181.amzn2.x86_64)
sudo amazon-linux-extras enable BCC
sudo yum install kernel-devel-$(uname -r)
sudo yum install bcc
As of Alpine 3.11, bcc binaries are available in the community repository:
sudo apk add bcc-tools bcc-doc
The tools are installed in /usr/share/bcc/tools.
Python Compatibility
The binary packages include bindings for Python 3 only. The Python-based tools assume that a python binary is available at /usr/bin/python, but that may not be true on recent versions of Alpine. If you encounter errors like <tool-name>: not found, you can try creating a symlink to the Python 3.x binary like so:
sudo ln -s $(which python3) /usr/bin/python
Containers
Alpine Linux is often used as a base system for containers. bcc can be used in such an environment by launching the container in privileged mode with kernel modules available through bind mounts:
sudo docker run --rm -it --privileged \
-v /lib/modules:/lib/modules:ro \
-v /sys:/sys:ro \
-v /usr/src:/usr/src:ro \
alpine:3.12
Since release v0.10.0, bcc starts to leverage libbpf repo (https://github.com/libbpf/libbpf) to provide wrapper functions to the kernel for bpf syscalls, uapi headers bpf.h/btf.h etc. Unfortunately, the default github release source code does not contain libbpf submodule source code and this will cause build issues.
To alleviate this problem, starting at release v0.11.0, source code with corresponding libbpf submodule codes will be released as well. See https://github.com/iovisor/bcc/releases.
The automated tests that run as part of the build process require netperf. Since netperf's license is not "certified"
as an open-source license, it is in Debian's non-free repository.
/etc/apt/sources.list should include the non-free repository and look something like this:
deb http://httpredir.debian.org/debian/ jessie main non-free
deb-src http://httpredir.debian.org/debian/ jessie main non-free
deb http://security.debian.org/ jessie/updates main non-free
deb-src http://security.debian.org/ jessie/updates main non-free
# wheezy-updates, previously known as 'volatile'
deb http://ftp.us.debian.org/debian/ jessie-updates main non-free
deb-src http://ftp.us.debian.org/debian/ jessie-updates main non-free
BCC also requires kernel version 4.1 or above. Those kernels are available in the jessie-backports repository. To
add the jessie-backports repository to your system create the file /etc/apt/sources.list.d/jessie-backports.list
with the following contents:
deb http://httpredir.debian.org/debian jessie-backports main
deb-src http://httpredir.debian.org/debian jessie-backports main
Note, check for the latest linux-image-4.x version in jessie-backports before proceeding. Also, have a look at the
Build-Depends: section in debian/control file.
# Before you begin
apt-get update
# Update kernel and linux-base package
apt-get -t jessie-backports install linux-base linux-image-4.9.0-0.bpo.2-amd64 linux-headers-4.9.0-0.bpo.2-amd64
# BCC build dependencies:
apt-get install debhelper cmake libllvm3.8 llvm-3.8-dev libclang-3.8-dev \
libelf-dev bison flex libedit-dev clang-format-3.8 python python-netaddr \
python-pyroute2 luajit libluajit-5.1-dev arping iperf netperf ethtool \
devscripts zlib1g-dev libfl-dev python-dnslib python-cachetools
Adding eBPF probes to the kernel and removing probes from it requires root privileges. For the build to complete
successfully, you must build from an account with sudo access. (You may also build as root, but it is bad style.)
/etc/sudoers or /etc/sudoers.d/build-user should contain
build-user ALL = (ALL) NOPASSWD: ALL
or
build-user ALL = (ALL) ALL
If using the latter sudoers configuration, please keep an eye out for sudo's password prompt while the build is running.
