* 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.

* geom_ccd.c: Fix the licenses properlyPedro F. Giffuni2017-12-301-19/+51
| | | | | | | | | | | | | | | The license merging in r109471 didn't take into account that licensing could change. Just removing the 3rd clause obviates the copyright assignment to the NetBSD Foundation. We do have plenty of files that have two or more licensing as in this case, so fix this properly by splitting back the licenses as they are upstream.

* geom_ccd.c: Update the license with changes from upstream.Pedro F. Giffuni2017-12-301-6/+2
| | | | | | | | | | | | | | | | | | Part of this file originated in NetBSD, with the original file carrying two versions of 4-clause BSD licenses. r109471 attempted to simplify the situation by putting both licenses together. Meanwhile, NetBSD dropped Clauses 3 and 4 from their own license, and eventually NetBSD got permission from the University of Utah to drop the 3rd clause. Keep the license "simple" by dropping the third clause since both TNF, Utah/Berkeley and phk agree in principle that it can be dropped.

* 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

| | | | | | | | | | | | | | error on the request. Add a wrapper, gctl_set_param_err(), that sets the error on the request from the error returned by gctl_set_param() and update current callers of gctl_set_param() to call gctl_set_param_err() instead. This makes gctl_set_param() much more usable in situations where the caller knows better what to do with certain (apparent) error conditions and setting an error on the request is not one of the things that need to be done.

* Finally give CCD the disk mini-layer treatment:Poul-Henning Kamp2003-01-191-431/+143
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CAUTION: Previously CCD would be different from all other disks in the system in that there were no "ccd0" device, only a "ccd0c" device. This is no longer so after this commit. If you access a ccd device through the "/dev/ccd0c" device _and_ have not actually put a BSD disklabel on the device, you will have to use the name "/dev/ccd0". If your CCD device contains a BSD disklabel there should be no difference. You need to recompile ccdconfig(8) using the changed src/sys/sys/ccdvar.h for the -g "show me" option to work. I have run the regression test I created before I started overhauling CCD and it flags no problems, but this code is mildly evil, so take care. If you would cry if you lost what's on CCD, make a back before you upgrade. Create separate cdevsw for the /dev/ccd.ctl device. Remove the cloning function, the disk-minilayer will do all naming for us. Remove the ccdunit and ccdpart functions and carry the softc pointer in the relevant dev_t's and structures. Release all memory when a CCD device is unconfigured, previously the softc would linger behind. Remove all traces of BSD disklabel fiddling code. Remove ccdpsize, the disk mini-layer does this for us. Don't allocate memory with M_WAITOK in ccdstrategy(). Remove boundary checks which the disk mini-layer does for us. Don't allocate space for more than 2 ccdbuf, RAID was never implemented. NB: I have not tried to address any of the preexisting ailments of CCD. Notes: svn path=/head/; revision=109535
