[PATCH v2 0/6] Convert CAN tests to new LTP API

[PATCH v2 0/6] Convert CAN tests to new LTP API

[Richard Palethorpe]

Hello,

This is an attempt to convert the CAN tests to the (modern) Linux Test
Project API and removes the wrapper script. To be clear, this is a
patch-set for the LTP *not* the kernel tree or can-utils.

I have tried to keep the core test behaviour the same, but (for
example) moving to the SAFE_ functions will naturally introduce some
changes in error checking. Deliberate behavioral changes have been
noted in the commit messages.

FYI, we appear to have 4 CAN tests in LTP including two tests for
SLCAN (pty03, pty04).

[PATCH v2 2/6] can: Add can_common.h for vcan device setup

[Richard Palethorpe]

Note that we call modprobe to set echo=1. However this does seem to be
necessary for the current tests on 5.10. It has been kept to avoid
changing the test behavior unnecessarily, but can most likely be
safely removed if it causes problems.

FYI IFF_ECHO is not defined on some older toolchains (aarch64).
It'd be good to add lapi/if.h, where it'd be defined.
But it can be added later.

In file included from can_common.h:21,
                 from can_filter.c:12:

Also there are other problems on toolchains with older linux headers
- bug in using <net/if.h> with <linux/if.h>. Can't we just use <linux/if.h>?

[PATCH v2 3/6] can_filter: Convert to new library

[Richard Palethorpe]

Behavior is mostly the same, but on some errors we print fail and
continue instead of exiting immediately. It appears this would result
in more information being printed if there is a failure.

[LTP] [PATCH v2 3/6] can_filter: Convert to new library

[Richard Palethorpe]

Behavior is mostly the same, but on some errors we print fail and
continue instead of exiting immediately. It appears this would result
in more information being printed if there is a failure.

[PATCH v2 4/6] can_recv_own_msgs: Convert to new library

[Richard Palethorpe]

Behavior is approximately the same except for the following:

* Test will continue after non-fatal errors.
* We now check the return value of `setsocketopt` and that I/O
  completed the specified number of bytes.
* The command line arg, device name, must be prepended with `-D`

Looks like we cannot just remove this license. So what about moving this
text into a separate COPYING file and changing the SPDX to GPL-v2.0?

HHmm, this appears to be the BSD-3-Clause license with the following
text inserted in the middle:

 * Alternatively, provided that this notice is retained in full, this
 * software may be distributed under the terms of the GNU General
 * Public License ("GPL") version 2, in which case the provisions of the
 * GPL apply INSTEAD OF those given above.
 *
 * The provided data structures and external interfaces from this code
 * are not restricted to be used by modules with a GPL compatible license.

I don't see any corresponding SPDX identifier or exception for this. It
is probably easiest and safest just to keep it as-is.

HHmm, this appears to be the BSD-3-Clause license with the following
text inserted in the middle:

 * Alternatively, provided that this notice is retained in full, this
 * software may be distributed under the terms of the GNU General
 * Public License ("GPL") version 2, in which case the provisions of the
 * GPL apply INSTEAD OF those given above.
 *

I don't see any corresponding SPDX identifier or exception for this. It
is probably easiest and safest just to keep it as-is.

I think the Linux kernel uses:

/* SPDX-License-Identifier: ((GPL-2.0-only WITH Linux-syscall-note) OR
BSD-3-Clause) */

e.g.:

https://elixir.bootlin.com/linux/v5.10/source/include/uapi/linux/can/gw.h

Yes, indeed it is a GPLv2 / BSD3 dual license to use it in both
