Public bug reported:
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.
