commitde0e30bee8upstream. Currently nettrace does not work on LoongArch due to missing bpf_probe_read{,str}() support, with the error message: ERROR: failed to load kprobe-based eBPF ERROR: failed to load kprobe-based bpf According to commit0ebeea8ca8("bpf: Restrict bpf_probe_read{, str}() only to archs where they work"), we only need to select CONFIG_ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE to add said support, because LoongArch does have non-overlapping address ranges for kernel and userspace.

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.
