Phoronix: A General Notification Queue Was Pushed Back From Linux 5.5 Introduction

Red Hat has been working on a "general notification queue" that is built off the Linux kernel's pipe code and will notify the user-space of events like key/keyring changes, block layer events like disk errors, USB attach/remove events, and other notifications without user-space having to continually poll kernel interfaces. This general notification queue was proposed for Linux 5.5 but has been pushed back to at least 5.6...

Another proof Red Hat does really care about Linux desktop. Hopefully it gets merged to 5.6.

Edit: thanks Ermo!

That's quite the retroactive merge...

Is this related to the in-kernel DBus interface implementation?

All events mentioned in the current specification are aimed at servers.

No, this will be more likely be a superior replacement for udev.

This could also notify when the PC chassis were opened.

import shutil
import subprocess
import os

def on_chassis_opened():
    """Physical intrusion into the computer detected."""
    shutil.rmtree('/home/alice/.gnupg', ignore_errors=True)
    shutil.rmtree('/home/alice/.pki/nssdb', ignore_errors=True)
    shutil.rmtree('/home/alice/.ssh', ignore_errors=True)
    shutil.rmtree('/etc/ssh', ignore_errors=True)
    shutil.rmtree('/etc/ssl/private', ignore_errors=True)
    shutil.rmtree('/etc/cups/ssl, ignore_errors=True)
    try:
        os.remove('/home/alice/Documents/secret_file.txt')
    except OSError:
        print('Could not remove file.')
    subprocess.run(['/bin/self-destruct', '--right-now'])
    subprocess.run(['umount', '-df', '/media/secret'])
    subprocess.run(['wall', 'Intrusion detected'])
    # Send email about intrusion
    # Wipe disk
    # Detonate explosives!

# Detonate explosives!

Poor Bob! Alice's security practices escalated rather quickly..

netlink?

I don't think so. I want to know about disk errors as a desktop user.

Whilst Red Hat does mantain a lot (maybe most?) of the Linux desktop stack, Red Hat as a company doesn't really care about the desktop, although many Red Hat employees do care passionately about the Linux desktop. Many (if not most) RHEL Workstation licenses are bundled free as part of bigger license agreements for RHEL. Red Hat cares about cloud because that's what makes money, not the Linux desktop.

Anyway, this functionality is awesome.
