Release v1.0.3

on GitHub

We are pleased to release the 1.0.3 version of pwru.

The major changes include:

• Added support for L2 filters. For example, to filter ARP replies you can run pwru 'arp and arp[6:2] == 2' (#255).
• Added --filter-ifname which allows users to select which device packets should be filtered. The option can be used with --filter-netns which was changed to accept either inode number (inode:) or a file path to a network namespace. For example, to filter only eth0 packets in the 42 pid's network namespace you can run pwru --filter-iface eth0 --filter-netns /proc/42/ns/net (#257).
• The --output-meta was extended to print a network interface name. For example, iface=3(wlan0) (#259).
