Opensnitch doesn't let through ICMP ECHO packets if the UI is running (original) (raw)

Greetings! I've encountered a bug in opensnitch that can cause numerious issues, including filesystem hangs for NFS and
generally broken behaviour in anything networked. I have pinpointed it to opensnitch not letting through outbound ICMP ECHO packets, but it only occurs if the UI is running.

Describe the bug
Opensnitch 1.4.0 blocks all ICMP ECHO packets when the UI is running. They do not show up on the log.

To Reproduce
Steps to reproduce the behavior:

1. Install opensnitch 1.4.0
2. Start opensnitchd
3. Run opensnitch-ui
4. Attempt to ping any host

Post error logs:
N/A

Expected behavior (optional)
Outbound ICMP ECHO packets aren't filtered.

Screenshots
N/A

OS (please complete the following information):

• OS: Bedrock Linux, opensnitch installed on the Debian stratum
• Window Manager: KWin
• Kernel version: Linux [hostname] 5.13.0-15.1-liquorix-amd64 #1 ZEN SMP PREEMPT liquorix 5.13-13.1~bookworm (2021-09-08) x86_64 GNU/Linux
• Version Debian 12/Bookworm

Additional context
This bug was not present in 1.3.6, but stopped working in one of the 1.4.0 RC's (I think it was .3, tell me if you want me to pinpoint it to a specific version).
