LiteSpeed QUIC (LSQUIC) Library README

Description

LiteSpeed QUIC (LSQUIC) Library is an open-source implementation of QUIC and HTTP/3 functionality for servers and clients. Most of the code in this distribution is used in our own products: LiteSpeed Web Server, LiteSpeed ADC, and OpenLiteSpeed.

Currently supported QUIC versions are v1, Internet-Draft versions 29, and 27; and the older "Google" QUIC versions Q043, Q046, an Q050.

Documentation

Documentation is available at https://lsquic.readthedocs.io/en/latest/.

In addition, see example programs for API usage and EXAMPLES.txt for some compilation and run-time options.

Requirements

To build LSQUIC, you need CMake, zlib, and BoringSSL. The example program uses libevent to provide the event loop.

Building BoringSSL

BoringSSL is not packaged; you have to build it yourself. The process is straightforward. You will need go installed.

1. Clone BoringSSL by issuing the following command:

git clone https://boringssl.googlesource.com/boringssl cd boringssl

You may need to install pre-requisites like zlib and libevent.

1. Use specific BoringSSL version

git checkout a2278d4d2cabe73f6663e3299ea7808edfa306b9

1. Compile the library

cmake . && make

Remember where BoringSSL sources are: BORINGSSL=$PWD

If you want to turn on optimizations, do

cmake -DCMAKE_BUILD_TYPE=Release . && make

If you want to build as a library, (necessary to build lsquic itself as as shared library) do:

cmake -DBUILD_SHARED_LIBS=1 . && make

Building LSQUIC Library

LSQUIC's http_client, http_server, and the tests link BoringSSL libraries statically. Following previous section, you can build LSQUIC as follows:

1. Get the source code

git clone https://github.com/litespeedtech/lsquic.git cd lsquic git submodule init git submodule update

1. Compile the library

Statically:

```

$BORINGSSL is the top-level BoringSSL directory from the previous step

cmake -DBORINGSSL_DIR=$BORINGSSL . make ```

As a dynamic library:

cmake -DLSQUIC_SHARED_LIB=1 -DBORINGSSL_DIR=$BORINGSSL . make

1. Run tests

make test

Building with Docker

The library and the example client and server can be built with Docker.

Initialize Git submodules: cd lsquic git submodule init git submodule update

Build the Docker image: docker build -t lsquic .

Then you can use the examples from the command line. For example: sudo docker run -it --rm lsquic http_client -s www.google.com -p / -o version=h3-29 sudo docker run -p 12345:12345/udp -v /path/to/certs:/mnt/certs -it --rm lsquic http_server -c www.example.com,/mnt/certs/chain,/mnt/certs/key

Platforms

The library has been tested on the following platforms: - Linux - i386 - x8664 - ARM (Raspberry Pi 3) - FreeBSD - i386 - MacOS - x8664 - Android - ARM - Windows - x86_64
