Tobias Stoeckmann 06ab0d166a sway: prevent endless loop with broken clients
The server loops endlessly in following scenarios:
- client sends less bytes than IPC header requires
- client sends less bytes than defined by payload size
- client sends more payload data than buffered by operating system

This happens because the server relies on the buffering in sockets by
the operating system. The server only retrieves bytes from buffer when
enough bytes are available. To prevent this, store data in heap.

Also check supplied payload length before working with that value.

Proof of Concept client in Python (you will notice that sway process
consumes a lot of CPU while the client is running):
```
import os
import socket

swaysock=os.environ['SWAYSOCK']
client = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)
client.connect(swaysock)
client.send(b'\x69\x33\x2D\x69\x70\x63\x00\x00\x00\x00\xFF\xFF\xFF\xFF\x00')
input('Press enter to quit.')
```

sway is an i3-compatible Wayland compositor. Read the FAQ. Join the IRC channel (#sway on irc.freenode.net).

Release Signatures

Releases are signed with E88F5E48 and published on GitHub.

Installation

From Packages

Sway is available in many distributions. Try installing the "sway" package for yours.

If you're interested in packaging sway for your distribution, stop by the IRC channel or shoot an email to sir@cmpwn.com for advice.

Compiling from Source

Check out this wiki page if you want to build the HEAD of sway and wlroots for testing or development.

Install dependencies:

  • meson *
  • wlroots
  • wayland
  • wayland-protocols *
  • pcre
  • json-c
  • pango
  • cairo
  • gdk-pixbuf2 (optional: system tray)
  • scdoc (optional: man pages) *
  • git (optional: version info) *

*Compile-time dep

Run these commands:

meson build/
ninja -C build/
sudo ninja -C build/ install

On systems without logind, you need to suid the sway binary:

sudo chmod a+s /usr/local/bin/sway

Sway will drop root permissions shortly after startup.

Configuration

If you already use i3, then copy your i3 config to ~/.config/sway/config and it'll work out of the box. Otherwise, copy the sample configuration file to ~/.config/sway/config. It is usually located at /etc/sway/config. Run man 5 sway for information on the configuration.

Running

Run sway from a TTY. Some display managers may work but are not supported by sway (gdm is known to work fairly well).
