GENL_ADMIN_PERM checks that the user has CAP_NET_ADMIN in the initial namespace by calling netlink_capable(). Instead, use GENL_UNS_ADMIN_PERM which uses netlink_ns_capable(). This checks that the caller has CAP_NET_ADMIN in the current user namespace. See also commit4a92602aa1("openvswitch: allow management from inside user namespaces") which introduced this mechanism. See also commit5617c6cd6f("nl80211: Allow privileged operations from user namespaces") which introduced this for nl80211.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
