False positives (chromium, cinnamon, electron) when using NVIDIA drivers on Arch

[starquake]

I did not update anything, but with nvidia drivers installed it says some services need updating, even immediately after boot. Any idea? Help to debug is appreciated.

When I run needrestart while using nouveau there are no services that need restarting. When I use nvidia drivers it reports "User sessions running outdated binaries".

A typical example:

 starquake @ session #3: chromium[1292,1317], cinnamon-launch[1161]
 starquake @ user manager service: electron[3241]

Running it with verbose:

[main] eval /etc/needrestart/needrestart.conf
[main] needrestart v3.5
[main] running in user mode
[Core] Using UI 'NeedRestart::UI::stdio'...
[main] systemd detected

Your outdated processes:

It looks like we need to put this weirrd /memfd:/.glXXXXXX mapping to the blacklist_mappings config option.

[starquake]

I can test this if you want. How would I do that?

[starquake]

I created the file /etc/needrestart/conf.d/ignore-memfd-gl.conf with contents:

push @{$nrconf{blacklist_mappings}}, qr#^/memfd:/.glXXXXXX#;

And that seems to help.

[liske]

This looks good - feel free to file a PR updating ex/needrestart.conf if you like.

@starquake Thank you for this fix and thank you @liske for your great work on this library. Is there any additional testing required before merging #200?

[liske]

Just a minor issue with the chosen quoting character (hashes vs. braces). I prefer to use the same characters in the default config.

Thanks for your contribution @starquake !
