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. We think it is free of major problems. Nevertheless, do
|
|
not hesitate to report bugs back to us. Even better, send us fixes and
|
|
improvements!
|
|
|
|
Currently supported QUIC versions are Q039, Q043, Q046, and ID-23. Support
|
|
for newer versions will be added soon after they are released.
|
|
|
|
Documentation
|
|
-------------
|
|
|
|
The documentation for this module is admittedly sparse. The API is
|
|
documented in include/lsquic.h. If you have doxygen, you can run
|
|
`doxygen dox.cfg` or `make docs`. The example program is
|
|
test/http_client.c: a bare-bones, but working, QUIC client. Have a look
|
|
in EXAMPLES.txt to see how it can be used.
|
|
|
|
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.
|
|
|
|
2. Use specific BoringSSL version
|
|
|
|
```
|
|
git checkout 49de1fc2910524c888866c7e2b0db1ba8af2a530
|
|
```
|
|
|
|
3. 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
|
|
```
|
|
|
|
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
|
|
```
|
|
|
|
2. Compile the library
|
|
|
|
|
|
```
|
|
# $BORINGSSL is the top-level BoringSSL directory from the previous step
|
|
cmake -DBORINGSSL_DIR=$BORINGSSL .
|
|
make
|
|
```
|
|
|
|
3. 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=Q046
|
|
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
|
|
- x86_64
|
|
- ARM (Raspberry Pi 3)
|
|
- FreeBSD
|
|
- i386
|
|
- MacOS
|
|
- x86_64
|
|
- Windows (this needs updating for the server part, now broken)
|
|
- x86_64
|
|
|
|
Have fun,
|
