wireguard-openbsd/sbin/bioctl, branch master

Make bioctl properly verify raidlevels specified via the -c option.

Trailing characters in the option argument were ignored, such that -cC1 (typo of -c1C) was interpreted as -cC instead of being rejected. ok jsing@

Add a RAID1C (raid1 + crypto) softraid(8) discipline.

2021-02-08T11:20:03Z

The RAID1C discipline encrypts data like the CRYPTO discipline, and accepts multiple chunks during creation and assembly like the RAID1 discipline. To deal with failing disks a RAID1C volume may be assembled with a smaller number of chunks than the volume was created with. The volume will then come up in degraded state. If the volume is now detached and assembled again with the correct number of chunks, any re-added chunks will require a rebuild. Consequently, assembling RAID1C volumes requires careful attention to the chunks passed via 'bioctl -l'. If a chunk is accidentally omitted from the command line during volume assembly, then this chunk will need to be rebuilt. At least one known-good chunk is required in order to assemble the volume. Like CRYPTO, RAID1C supports passphrase and key-disk authentication. Key-disk based volumes are assembled automatically if the key disk is present while the system is booting up. Unlike CRYPTO and RAID1, there is no boot support for RAID1C yet. RAID1C largely reuses existing code of RAID1 and CRYPTO disciplines. At present RAID1C's discipline-specific data structure is shared with that of the CRYPTO discipline to allow re-use of existing CRYPTO code. A custom RAID1C data structure would require CRYPTO code to access struct sr_crypto via a pointer instead of via a member field of struct sr_discipline. ok jsing@

Do not use ".Ar device" for both an option argument and for the operand.

2020-10-30T13:55:48Z

Instead, use ".Ar chunk" for the -R option argument just like it is already done for -l and -O. While here, polish a few minor details in the vicinity of the word "device". OK kn@

1. This increases the number of volumes that can be created on a single disk from 7 to 15. i.e. a disk can be sliced into a maximum of 225 (15 * 15) filesystems instead of a mere 105 (7 * 15). ok deraadt@

that there is only one softraid(4) controller (called softraid0), and clarify that you cannot add or delete chunks, but merely replace them. Tweaks and OK jsing@, and OK henning@ on a previous version.
