Linux kernel source tree
7ec899ac90
This patch adds a test case, as shown below, for the verifier error
"more than one arg with ref_obj_id".
0: (b7) r2 = 20
1: (b7) r3 = 0
2: (18) r1 = 0xffff92cee3cbc600
4: (85) call bpf_ringbuf_reserve#131
5: (55) if r0 == 0x0 goto pc+3
6: (bf) r1 = r0
7: (bf) r2 = r0
8: (85) call bpf_tcp_raw_gen_syncookie_ipv4#204
9: (95) exit
This error is currently incorrectly reported as a verifier bug, with a
warning. The next patch in this series will address that.

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 reStructuredText 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.
