* Document the mntopts(3) functions.Kirk McKusick2023-01-156-201/+487
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mntopts(3) functions support operations associated with a mount point. The main purpose of this commit is to document the mntopts(3) functions that now appear in 18 utilities in the base system. See mntopts(3) for the documentation details. The getmntopts() function appeared in 4.4BSD. The build_iovec(), build_iovec_argf(), free_iovec(), checkpath(), and rmslashes() functions were added with nmount(8) in FreeBSD 5.0. The getmntpoint() and chkdoreload() functions are being added in this commit. These functions should be in a library but for historic reasons are in a file in the sources for the mount(8) program. Thus, to access them the following lines need to be added to the Makefile of the program wanting to use them: SRCS+= getmntopts.c MOUNT= ${SRCTOP}/sbin/mount CFLAGS+= -I${MOUNT} .PATH: ${MOUNT} Once these changes have been MFC'ed to 13 they may be made into a library.

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.

* vfs_donmount: in certain cases try r/o mount if r/w mount failsAndriy Gapon2018-03-271-0/+4
| | | | | | | | | | | | | | | | | | | | | | If the operation is not an update, if neither r/w nor r/o mode is explicitly requested, if the error code hints at the possibility of the media being read-only, and if the fallback is allowed, then we can try to automatically downgrade to the readonly mode. This is especially useful for auto-mounting of removable media that sometimes can happen to be write-protected. The fallback to r/o is not enabled by default. It can be requested on a per-mount basis with a new mount option, 'autoro'. Or it can be globally allowed by setting vfs.default_autoro.

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.
