* Annotate geom modules with MODULE_VERSIONKyle Evans2018-04-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | GEOM ELI may double ask the password during boot. Once at loader time, and once at init time. This happens due a module loading bug. By default GEOM ELI caches the password in the kernel, but without the MODULE_VERSION annotation, the kernel loads over the kernel module, even if the GEOM ELI was compiled into the kernel. In this case, the newly loaded module purges/invalidates/overwrites the GEOM ELI's password cache, which causes the double asking. MFC Note: There's a pc98 component to the original submission that is omitted here due to pc98 removal in head. This part will need to be revived upon MFC.

* sys/geom: adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326270

* Rename the kthread_xxx (e.g. kthread_create()) callsJulian Elischer2007-10-201-1/+1
| | | | | | | | | | | | | | to kproc_xxx as they actually make whole processes. Thos makes way for us to add REAL kthread_create() and friends that actually make theads. it turns out that most of these calls actually end up being moved back to the thread version when it's added. but we need to make this cosmetic change first.

* Add Geom Based Disk Encryption to the tree.Poul-Henning Kamp2002-10-191-0/+282
This is an encryption module designed for to secure denial of access to the contents of "cold disks" with or without destruction activation. Major features: * Based on AES, MD5 and ARC4 algorithms. * Four cryptographic barriers: 1) Pass-phrase encrypts the master key. 2) Pass-phrase + Lock data locates master key. 3) 128 bit key derived from 2048 bit master key protects sector key. 3) 128 bit random single-use sector keys protect data payload. * Up to four different changeable pass-phrases. * Blackening feature for provable destruction of master key material. * Isotropic disk contents offers no information about sector contents. * Configurable destination sector range allows steganographic deployment. This commit adds the kernel part, separate commits will follow for the userland utility and documentation. This software was developed for the FreeBSD Project by Poul-Henning Kamp and NAI Labs, the Security Research Division of Network Associates, Inc. under DARPA/SPAWAR contract N66001-01-C-8035 ("CBOSS"), as part of the DARPA CHATS research program.
