Users namespaces not available in 5.4.23
Hi,
This is a newbie question but I'm scratching my head over it.
/proc/sys/kernel/unprivileged_userns_clone is absent from my system.
But:
zgrep CONFIG_NAMESPACES /proc/config.gz
CONFIG_NAMESPACES=y
and:
zgrep USER_NS /proc/config.gz
CONFIG_USER_NS=y
Any ideas?
Thank you

Re: Users namespaces not available in 5.4.23
linux-lts dropped all out of tree patches with https://git.archlinux.org/svntogit/pack … 2fc32487f1
so user namespaces are always available to all users in linux-lts 5.4.23.

That's a bug, I've nudged someone to fix it. Unprivileged USER_NS should not be enabled without a sysctl to disable it.

+CONFIG_USER_NS_UNPRIVILEGED=yWith the patch, re-added, to make this default toggleable and overrideable via the sysctl you expected.
