Could you refer to some documentation on this restriction (especially - what actions are allowed/restricted)?
In addition - what was the reason of DROP behaviour? All known to me system restrictions behave as REJECT - i.e. restricted action gets an immediate result instead on being stuck until the timeout expires... -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1839156 Title: TCP/IP connection stuck when called from UDEV rule Status in systemd package in Ubuntu: Invalid Bug description: It seems that in Eoan there is a lock/any other issue preventing particular system calls to be executed by the triggered action handler. I have an action executing wget when USB-serial adapter is plugged: SUBSYSTEM=="tty", ACTION=="add", ATTRS{idVendor}=="1a86", ATTRS{idProduct}=="7523", MODE="0666", RUN+="/usr/bin/wget -v --method=POST http://127.0.0.1:4000/udev_trigger/add"; This action works perfectly in a prior versions - but in Eoan Ermine it hangs for ~30s and fails on a timeout. Analysis with strace shows that execution is stuck on connect() syscall - until it returns with ETIMEDOUT. Same Wget command, being run from a command line, works perfectly. The issue doesn't seem to be related to a particular IP (localhost/remote) and/or the status of a listener process - execution hangs also when listener is not running and port is free.
