Seems like that extra bpf_capable() check in BPF_MAP_FREEZE handler was unintentionally left when we switched to a model that all BPF map operations should be allowed regardless of CAP_BPF (or any other capabilities), as long as process got BPF map FD somehow. This patch replaces bpf_capable() check in BPF_MAP_FREEZE handler with writeable access check, given conceptually freezing the map is modifying it: map becomes unmodifiable for subsequent updates.

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.
