Installing BCC

Kernel Configuration

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
# Need kernel headers through /sys/kernel/kheaders.tar.xz
CONFIG_IKHEADERS=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>.

Packages

Debian - Binary

bcc and its tools are available in the standard Debian main repository, from the source package bpfcc under the names bpfcc-tools, python3-bpfcc, libbpfcc and libbpfcc-dev.

To install:

echo deb http://cloudfront.debian.net/debian sid main >> /etc/apt/sources.list
sudo apt-get install -y bpfcc-tools libbpfcc libbpfcc-dev linux-headers-$(uname -r)

Ubuntu - Binary

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Currently, BCC packages for both the Ubuntu Universe, and the iovisor builds are outdated.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:

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.

iovisor packages (Upstream Stable and Signed Packages)

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 4052245BD4284CDD

sudo apt-get update
sudo apt-get install bcc-tools libbcc-examples linux-headers-$(uname -r)

(replace xenial with artful or bionic as appropriate). Tools will be installed under /usr/share/bcc/tools.

Upstream Nightly Packages

(replace xenial with artful or bionic as appropriate)

Fedora - Binary

Fedora 30 and newer

As of Fedora 30, bcc binaries are available in the standard repository. You can install them via

sudo dnf install bcc

Note: 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).

Fedora 29 and older

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
# reboot

Nightly Packages

Nightly bcc binary packages for Fedora 25, 26, 27, and 28 are hosted at https://repo.iovisor.org/yum/nightly/f{25,26,27}.

To install:

echo -e '[iovisor]\nbaseurl=https://repo.iovisor.org/yum/nightly/f27/$basearch\nenabled=1\ngpgcheck=0' | sudo tee /etc/yum.repos.d/iovisor.repo
sudo dnf install bcc-tools kernel-headers kernel-devel

Stable and Signed Packages

Stable bcc binary packages for Fedora 25, 26, 27, and 28 are hosted at https://repo.iovisor.org/yum/main/f{25,26,27}.

echo -e '[iovisor]\nbaseurl=https://repo.iovisor.org/yum/main/f27/$basearch\nenabled=1' | sudo tee /etc/yum.repos.d/iovisor.repo
sudo dnf install bcc-tools kernel-devel-$(uname -r) kernel-headers-$(uname -r)

Arch - Binary

bcc is available in the standard Arch repos, so it can be installed with the pacman command:

# pacman -S bcc bcc-tools python-bcc

Gentoo - Portage

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.

openSUSE - Binary

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-examples

RHEL - Binary

For 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

Amazon Linux 1 - Binary

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

Amazon Linux 2 - Binary

Use case 1. Install BCC for your AMI's default kernel (no reboot required): Tested on Amazon Linux AMI release 2021.11 (kernel 5.10.75-79.358.amzn2.x86_64)

sudo amazon-linux-extras install BCC

Alpine - Binary

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

WSL(Windows Subsystem for Linux) - Binary

Install dependencies

The compiling depends on the headers and lib of linux kernel module which was not found in wsl distribution packages repo. We have to compile the kernel module manually.

apt-get install flex bison libssl-dev libelf-dev dwarves bc

Install packages

First, you will need to checkout the WSL2 Linux kernel git repository:

KERNEL_VERSION=$(uname -r | cut -d '-' -f 1)
git clone --depth 1 https://github.com/microsoft/WSL2-Linux-Kernel.git -b linux-msft-wsl-$KERNEL_VERSION
cd WSL2-Linux-Kernel

Then compile and install:

cp Microsoft/config-wsl .config
make oldconfig && make prepare
make scripts
make modules
sudo make modules_install

After install the module you will need to change the name of the directory to remove the '+' at the end

mv /lib/modules/$KERNEL_VERSION-microsoft-standard-WSL2+/ /lib/modules/$KERNEL_VERSION-microsoft-standard-WSL2

Then you can install bcc tools package according your distribution.

If you met some problems, try to

sudo mount -t debugfs debugfs /sys/kernel/debug

Source

libbpf Submodule

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.
