Daniel Borkmann cda18e9726 Merge branch 'bpf-dump-and-disasm-nfp-jit'
Jakub Kicinski says:

====================
Jiong says:

Currently bpftool could disassemble host jited image, for example x86_64,
using libbfd. However it couldn't disassemble offload jited image.

There are two reasons:

  1. bpf_obj_get_info_by_fd/struct bpf_prog_info couldn't get the address
     of jited image and image's length.

  2. Even after issue 1 resolved, bpftool couldn't figure out what is the
     offload arch from bpf_prog_info, therefore can't drive libbfd
     disassembler correctly.

  This patch set resolve issue 1 by introducing two new fields "jited_len"
and "jited_image" in bpf_dev_offload. These two fields serve as the generic
interface to communicate the jited image address and length for all offload
targets to higher level caller. For example, bpf_obj_get_info_by_fd could
use them to fill the userspace visible fields jited_prog_len and
jited_prog_insns.

  This patch set resolve issue 2 by getting bfd backend name through
"ifindex", i.e network interface index.

v1:
 - Deduct bfd arch name through ifindex, i.e network interface index.
   First, map ifindex to devname through ifindex_to_name_ns, then get
   pci id through /sys/class/dev/DEVNAME/device/vendor. (Daniel, Alexei)

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
