* various: general 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. No functional change intended.

* Add ability to label md(4) devices.Maxim Sobolev2017-08-281-8/+18
| | | | | | | | | | | | | | | This feature comes from the fact that we rely memory-backed md(4) in our build process heavily. However, if the build goes haywire the allocated resources (i.e. swap and memory-backed md(4)'s) need to be purged. It is extremely useful to have ability to attach arbitrary labels to each of the virtual disks so that they can be identified and GC'ed if neecessary.

* Add MD_VERIFY option to enable O_VERIFY in open for vnode type.Stephen J. Kiernan2017-05-311-0/+4
| | | | | | | | | | | | | | | | Add -o [no]verify option to mdconfig (and document in man page.) Implement GEOM attribute MNT::verified to ask md if the backing vnode is verified. Check for MNT::verified in cd9660 mount to flag the mount as MNT_VERIFIED if the underlying device has been verified.

When returning md(4) device details to the caller, include the file name in any MD_PRELOAD type devices if it is set (first character is not NUL.) In mdconfig, for "preload" type md(4) devices, if there is file config available, print it in the file column of the output.
