* mdmfs(8): add -k skel option to populate fs from a skeletonKyle Evans2019-11-012-5/+35
| | | | | | | | | | | | | | | | | | | | | | | mdmfs(8) lacks the ability to populate throwaway memory filesystems from an existing directory. This features permits an interesting setup where /var for instance lives on a device where wear-leveling is something you want to avoid as much as possible and nonetheless you don't want to lose your logs, ports metadata, etc. Here are the steps: 1. Copy /var to /var.bak; 2. Mount an mfs into /var using -k /var.bak at startup; 3. Synchronize /var to /var.bak weekly and on shutdown. Note that this more or less mimics OpenBSD's mount_mfs(8) -P flag. PR: 146254 Submitted by: jlh (many moons ago) MFC after: 1 week Notes: svn path=/head/; revision=354236
* mdmfs(8): use -o reserve with malloc-backed md(4)Kyle Evans2019-02-161-0/+1
| | | | | | | | | | | | | Mentioned in mdconfig(8), malloc-backed md(4) can be unstable unless required memory is allocated up front with -o reserve. Furthermore, panics have been observed with md used in fstab on 12.0-RELEASE. Choose the stable route and pass -o reserve.

* mdmfs: Fix many bugs in automatic md(4) creation.Brooks Davis2019-02-111-8/+9
| | | | | | | | | | | | | | | | | | | | | | | | This code allocated a correctly sized buffer, read past the end of the source buffer, writing off the end of the target buffer, and then writing a '\0' terminator past the end of the target buffer (in the wrong place). It then leaked the buffer. Switch to a statically sized buffer on the stack and update the source pointer and length before use so the correct things are copied. Fix a logic error in the checks that the format of the line is as expected and move on out of an assert. Remove an unneeded close(). fclose() closes the descriptor.

| | | | | | | | | | | | | | | | | | | | | Exiting with a signal should not be treated the same as successful exit with zero status. Return signal exit information to the callers via negative integers, to enable distinction from normal exit statuses. (All consumers that check for errors don't care what the exact non-zero exit value is -- in such a case they print a diagnostic message and either continue or bail.) Additionally, check for unexpected sources of waitpid() wakeup and bail if we encounter them.

* various: general adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-1/+3
| | | | | | | | | | | | | | | | | 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.

* Enhance mdmfs(8) to work with tmpfs(5).Ian Lepore2017-09-292-50/+178
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Existing scripts and associated config such as rc.initdiskless, rc.d/var, and others, use mdmfs to create memory filesystems. That program accepts a size argument which allows SI suffixes and treats an unsuffixed number as a count of 512 byte sectors. That makes it difficult to convert existing scripts to use tmpfs instead of mdmfs, because tmpfs treats unsuffixed numbers as a count of bytes. The script logic to deal with existing user config that might include suffixed and unsuffixed numbers is... unpleasant. Also, there is no g'tee that tmpfs will be available. It is sometimes configured out of small-resource embedded systems to save memory and flash storage space. These changes enhance mdmfs(8) so that it accepts two new values for the 'md-device' arg: 'tmpfs' and 'auto'. With tmpfs, the program always uses tmpfs(5) (and fails if it's not available). With 'auto' the program prefers tmpfs, but falls back to using md(4) if tmpfs isn't available. It also handles the -s <size> argument so that the mdconfig interpetation of unsuffixed numbers applies when tmpfs is used as well, so that existing user config keeps working after a switch to tmpfs. A new rc setting, mfs_type, is added to etc/defaults/rc.conf to let users force the use of tmpfs or md; the default value is "auto".

* Fix a typo: argv -> argvpYaroslav Tykhiy2007-04-301-1/+2
| | | | | | | | | | | | | | | | | | | | | | | Rationale: We are interested in the current (last) element of the argv array there, not in its first element. The if construct is there because we want to avoid adding empty (zero-length) arguments to argv, so we just don't advance argvp if the current argument is empty, and it gets overwritten at the next iteration. Note that strsep(3) doesn't treat consecutive delim characters as a single separator, it returns empty fields between such characters, and it's up to the caller to handle them this or that way. Also add a comment that the argv array ends up null-terminated in any case (it's due to the design of the for loop) as an answer to a possible question why the whole argv isn't zero-filled.

Worse, the compatibility mode makes it impossible to mount_mfs(8) a file system from fstab(5) with soft updates disabled (-S). [1] Now, the only difference when called as "mount_mfs" or "mfs" (as opposed to "mdmfs") is that the file mode of the mount point is set by default to 01777. All options available to mdmfs(8) are also available to mount_mfs(8); the -C option is still recognized but ignored for backward compatibility.

| | | | | | | | | | | | | | | | | | | | disk. Apparently some people want to use mdmfs as mount_* as a shortcut for mounting existing file-based file systems. Note that unlike in the patches from the submitters, this option is not available in compat mode. Compat mode was supposed to support only things that mount_mfs used to support. To use this option from fstab, mdmfs should be called mount_md, not mount_mfs. This distinction has not always upkept for new options, and those can't be fixed now without breaking people's systems, but new options should not usually be allowed in compat mode.

Instead they also have to be set in case the string to integer conversion was successful. Additionally, as a result of this fix, two assertions at the end of the function are now always true and hence can be just be removed. It is guarrantied that both the UID and the GID are set when the function returns regularily, else it would have been already bailed out with usage()/exit(3) or errx(3) before.
