* manpages: prefer linking to xo_options.7 over xo_parse_args.3Alan Somers2025-07-161-3/+3
| | | | | | | | | | | | | | | Most libxo-enabled utilities link to xo_parse_args.3. But that man page doesn't actually describe how to format command-line arguments. Rather, xo_options.7 does. I suspect that these utilities link to the former because the latter man page did not exist until libxo-0.7.2 (8a6eceff3ce). And newer utilities have probably been copy/pasting the same text from older ones. But the superior man page does exist now, so we should link to it instead.

* Move mntopts(3) suppport into libutilBrooks Davis2025-04-224-799/+2
| | | | | | | | | | | | | | | | | Many programs use this functionality so it should be available centrally rather than compiled into each program independently. This has the modest downside of adding libutil dependencies to some mount_<foo> programs, but many (plus mount(8)) already have those depndencies so this shouldn't be a major imposition. In commit 906c312bbf74, Kirk said this could be done once the change was merged to FreeBSD 13. That happened in commit 668dfa016698 in 2023.

* mount(8): Avoid truncation when fstab-formatting unionfs mount infoJason A. Harmening2024-12-301-8/+8
| | | | | | | | | | | | | | | | When displaying unionfs mounts in fstab format (`mount -p`), mount(8) currently uses strlcpy to remove the disposition prefix from the mount name returned by getmntinfo(3). But strlcpy, like strcpy before it, does not guarantee correct behavior if the source and destination buffers overlap. Just offset the buffer and avoid the destructive copy in the first place.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
