firewire: core: add test for beyond-boundary case in config ROM generator

2026-09-02T23:59:09+00:00

Although unit drivers and userspace applications are allowed to extend the system configuration ROM, they could provide invalid extension data. Add a KUnit test to verify that the generator does not write beyond the boundary of the configuration ROM when handling an extension.

firewire: core: add invalid block test for config ROM generator

2026-09-02T23:59:08+00:00

Although the unit drivers and the userspace applications are allowed to extend the system configuration ROM, they could provide invalid extension data. Add a KUnit test to verify that the generator handles an invalid block. Link: https://lore.kernel.org/r/20260901134534.2386577-13-o-takashi@sakamocchi.jp Signed-off-by: Takashi Sakamoto

firewire: core: add test for invalid length in config ROM generator

2026-09-02T23:59:08+00:00

Although the unit drivers and the userspace applications are allowed to extend the system configuration ROM, they could provide invalid extension data. Add a KUnit test to verify that the generator handles an extension with an invalid length.

firewire: core: add test to generate with both AV/C and IIDC units in config ROM generator

2026-09-02T23:59:08+00:00

Add a KUnit test to verify that the generator produces the expected configuration ROM when both AV/C and IIDC units are registered. Link: https://lore.kernel.org/r/20260901134534.2386577-11-o-takashi@sakamocchi.jp Signed-off-by: Takashi Sakamoto

firewire: core: add test to generate with IIDC unit in config ROM generator

2026-09-02T23:59:08+00:00

There is a standard layout of configuration ROM for IIDC devices. Add a KUnit test to verify that the generator produces the expected configuration ROM when an IIDC unit is registered. Link: https://lore.kernel.org/r/20260901134534.2386577-10-o-takashi@sakamocchi.jp Signed-off-by: Takashi Sakamoto

firewire: core: add test for root directory generation in config ROM generator

2026-09-02T23:59:08+00:00

The core function allows both the unit drivers and the userspace applications to extend the system configuration ROM. Without any extensions, the generator produces a root directory accompanied by two descriptor leaves. Add a KUnit test to verify the configuration ROM generated in this case.

firewire: core: add test to avoid excessive configuration ROM length

2026-09-02T23:59:08+00:00

The configuration ROM parser needs to handle malformed ROM contents safely. In particular, malformed directory and leaf offsets and block lengths should not result in accesses beyond the available configuration ROM data. Add a KUnit test with malformed configuration ROM content to verify that the parser sanitizes entries that would cause accesses beyond the available configuration ROM data.

firewire: core: add test to detect unstable-at-s400 quirk in config ROM parser

2026-09-02T23:59:08+00:00

TASCAM FireWire series devices have a quirk where they fail to respond to asynchronous transactions at S400 speed. This quirk was supported by commit d52bb3daad3f ("firewire: core: handle device quirk of TASCAM FW-1884/FW-1804/FW-1082"). Add a KUnit test to verify that the configuration ROM parser detects the quirk correctly. The configuration ROM content is retrieved from the author's collection.

firewire: core: add test to detect ack-packet-with-invalid-pending-code quirk in config ROM parser

2026-09-02T23:59:08+00:00

MOTU Audio Express has a quirk where it transfers an invalid pending code when receiving an asynchronous request. This quirk was originally reported by commit 3a93d082bacf ("ALSA: firewire-motu: add support for MOTU Audio Express") and later supported by commit 15f9610fc96a ("firewire: core: handle device quirk of MOTU Audio Express"). Add a KUnit test to verify that the configuration ROM parser detects the quirk correctly. The configuration ROM content is retrieved from the commit mentioned above.
