I've noticed that with the Liquorix kernel, Chrome reports that support for PID and network namespaces (used by Chrome's SUID sandbox) isn't available. According to phajdan-jr.blogspot.com/2011/05/chromium-linux-kernel-configuration.html, this is needed to make Chrome's SUID sandbox fully effective.

(Here's a screenshot of about:sandbox that shows this)


Debian's stock kernel supports this...
:: Code ::
$ cat /boot/config-3.0.0-1-amd64
[...]
CONFIG_PID_NS=y
CONFIG_NET_NS=y


...while Liquorix does not.
:: Code ::
$ cat /boot/config-2.6.39-4.dmz.1-liquorix-amd64
[...]
# CONFIG_PID_NS is not set
# CONFIG_NET_NS is not set


Why is PID/network namespace support enabled in the stock Debian kernel, and not in Liquorix? I don't know if there are any downsides to this, but would you kindly consider enabling PID/network namespace support in Liquorix?

Thanks for the notice. I'll make this change in the next kernels I build. This weekend I'll be working on the 3.0 kernel since Con finished porting his CK patches over to the new kernel.

EDIT: These features were disabled because I didn't know what used them, really as simple as that. Whenever presents to me a use case that doesn't hinder everyone else, I'll enable the feature for them.
