Multiple Linux Distributions Affected By Crippling Bug In Systemd (agwa.name)

An anonymous reader writes: System administrator Andrew Ayer has discovered a potentially critical bug in systemd which can bring a vulnerable Linux server to its knees with one command. "After running this command, PID 1 is hung in the pause system call. You can no longer start and stop daemons. inetd-style services no longer accept connections. You cannot cleanly reboot the system." According to the bug report, Debian, Ubuntu, and CentOS are among the distros susceptible to various levels of resource exhaustion. The bug, which has existed for more than two years, does not require root access to exploit.

This is not a bug, it's a feature. This is the systemd way and you've all being doing it wrong!

Whew! Thank goodness I run Red Hat!

That's a bit more code than a traditional Unix init system...

That's a bit more code than an old-school Unix system.

EMACS and systemd are both credible complete operating systems, but EMACS is lighter weight, includes a web browser, and can emit textual log files. It's a clear victory for EMACS.

I've always loved the multiple meanings in "the boat is fast". Just like the word "secure", it can mean wildly different things:

If you give the command "SECURE THE BUILDING", here is what the different services would do:

The NAVY would turn out the lights and lock the doors.

The ARMY would surround the building with defensive fortifications, tanks and concertina wire.

The MARINE CORPS would assault the building, using overlapping fields of fire from all appropriate points on the perimeter.

The AIR FORCE would take out a three-year lease with an option to buy the property.
