Whiledbecd73884("bpf: get kernel symbol addresses via syscall") zeroed info.nr_jited_ksyms in bpf_prog_get_info_by_fd() for queries from unprivileged users, commit815581c11c("bpf: get JITed image lengths of functions via syscall") forgot about doing so and therefore returns the #elems of the user set up buffer which is incorrect. It also needs to indicate a info.nr_jited_func_lens of zero.

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.
