* Add two options to allow mount to avoid covering up existing mount points.Sean Eric Fagan2019-09-231-2/+5
| | | | | | | | | | | | | | | | | | | The two options are * nocover/cover: Prevent/allow mounting over an existing root mountpoint. E.g., "mount -t ufs -o nocover /dev/sd1a /usr/local" will fail if /usr/local is already a mountpoint. * emptydir/noemptydir: Prevent/allow mounting on a non-empty directory. E.g., "mount -t ufs -o emptydir /dev/sd1a /usr" will fail. Neither of these options is intended to be a default, for historical and compatibility reasons.

* Add a new "untrusted" option to the mount command. Its purposeKirk McKusick2019-07-011-1/+3
| | | | | | | | | | | | | | | | | | | is to notify the kernel that the file system is untrusted and it should use more extensive checks on the file-system's metadata before using it. This option is intended to be used when mounting file systems from untrusted media such as USB memory sticks or other externally-provided media. It will initially be used by the UFS/FFS file system, but should likely be expanded to be used by other file systems that may appear on external media like msdosfs, exfat, and ext2fs.

* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. 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. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326025
* Renumber copyright clause 4Warner Losh2017-02-281-1/+1
| | | | | | | | | | | | Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

This whole getmntopt() business is an incredible botch; it never should have been anything more than a wrapper around getsubopt(3). Because if the way the current hackaround is implemented, options which take arguments (like the old `rsize' and `wsize') are still unavailable, and must be accessed the new, broken way.
