Add sunlabel, a more or less drop in replacement for bsd^H^H^Hdisklabel(8) which works on sun labels. Due to the lack of an interface other than write(2) to update labels, it cannot modify an open partition.

General further adoption of SPDX licensing ID tags. 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.

- Use read(2) to get the existing sunlabel on a disk, instead of parsing kern.geom.conftxt, which md disks don't show up in. If the magic and the checksum are right assume its a valid sunlabel, otherwise use the DIOC ioctls to get the disk parameters and whip up a label out of thin air. - Don't just silently create or correct invalid c partitions, warn about invalid ones in label proto files. - Split checksumming into a function since we do it a couple times. Also don't include the sl_cksum field in the checksum, which avoids needing to clear it first. This is makes sunlabel a suitable replacement for disklabel in make release.

When editing a Sun label, make the search for a valid partition line violate POLA a little less by not requiring exactly two spaces in front of the entry (and silently discarding any non-matching entry). We now recognize anything starting with a letter followed by a colon as the first non-space chars as a partition entry.

Major overhaul of sunlabel(8). . Implement option -c, all partition sizes will be calculated in cylinders as opposed to sectors. Since the Sun label is inherently cylinder-based, this makes the job a little easier. . Implement option -h, print the label in `human readable' size/offset format. . Implement SVR4-compatible VTOC-style elements. They are fully optional, defaulting to the current behaviour where no VTOC-style table will be written to disk. However, if desired, the full functionality of the partitioning menu of Solaris' format(1m) is now offered (and even more). . When editing the label, do not loop around edit_label() where a new template file is generated for each turn, this used to be annoying in that any possible syntax error caused a complaint, but then the template was created anew, so the user had to perform all their editing again. Rather loop inside edit_label(), similar to bsdlabel(8), so in case of errors, the user will be presented their previous template file again. . If VTOC-style elements are present, the overlap checks are made less stringent. Overlaps will still be warned about, but overlaps of `unmountable' partitions against other ones are no longer fatal. That way, e. g. VxVM encapsulated disk labels can be fully edited in FreeBSD (but not in Solaris ;-). . In print_label(), generate the editing hints only if the -e flag is in effect. Additionally, print a hint about the total number of sectors in the (hardware) medium. . When editing a label, allow for changing the geometry emulation (and textual name) by modifying the "text:" line on top. That way, a more effective emulation can be chosen. . When editing/reading a label, additionally allow for the suffixes `s' (512-byte sectors), and `c' (cylinders) in the partition size field. . Finally, turn the stub man page into something that really explains the entire thing.

Major overhaul of sunlabel(8). . Implement option -c, all partition sizes will be calculated in cylinders as opposed to sectors. Since the Sun label is inherently cylinder-based, this makes the job a little easier. . Implement option -h, print the label in `human readable' size/offset format. . Implement SVR4-compatible VTOC-style elements. They are fully optional, defaulting to the current behaviour where no VTOC-style table will be written to disk. However, if desired, the full functionality of the partitioning menu of Solaris' format(1m) is now offered (and even more). . When editing the label, do not loop around edit_label() where a new template file is generated for each turn, this used to be annoying in that any possible syntax error caused a complaint, but then the template was created anew, so the user had to perform all their editing again. Rather loop inside edit_label(), similar to bsdlabel(8), so in case of errors, the user will be presented their previous template file again. . If VTOC-style elements are present, the overlap checks are made less stringent. Overlaps will still be warned about, but overlaps of `unmountable' partitions against other ones are no longer fatal. That way, e. g. VxVM encapsulated disk labels can be fully edited in FreeBSD (but not in Solaris ;-). . In print_label(), generate the editing hints only if the -e flag is in effect. Additionally, print a hint about the total number of sectors in the (hardware) medium. . When editing a label, allow for changing the geometry emulation (and textual name) by modifying the "text:" line on top. That way, a more effective emulation can be chosen. . When editing/reading a label, additionally allow for the suffixes `s' (512-byte sectors), and `c' (cylinders) in the partition size field. .

Major overhaul of sunlabel(8). . Implement option -c, all partition sizes will be calculated in cylinders as opposed to sectors. Since the Sun label is inherently cylinder-based, this makes the job a little easier. . Implement option -h, print the label in `human readable' size/offset format. . Implement SVR4-compatible VTOC-style elements. They are fully optional, defaulting to the current behaviour where no VTOC-style table will be written to disk. However, if desired, the full functionality of the partitioning menu of Solaris' format(1m) is now offered (and even more). . When editing the label, do not loop around edit_label() where a new template file is generated for each turn, this used to be annoying in that any possible syntax error caused a complaint, but then the template was created anew, so the user had to perform all their editing again. Rather loop inside edit_label(), similar to bsdlabel(8), so in case of errors, the user will be presented their previous template file again. . If VTOC-style elements are present, the overlap checks are made less stringent. Overlaps will still be warned about, but overlaps of `unmountable' partitions against other ones are no longer fatal. That way, e. g. VxVM encapsulated disk labels can be fully edited in FreeBSD (but not in Solaris ;-). . In print_label(), generate the editing hints only if the -e flag is in effect.

Major overhaul of sunlabel(8). . Implement option -c, all partition sizes will be calculated in cylinders as opposed to sectors. Since the Sun label is inherently cylinder-based, this makes the job a little easier. . Implement option -h, print the label in `human readable' size/offset format. . Implement SVR4-compatible VTOC-style elements. They are fully optional, defaulting to the current behaviour where no VTOC-style table will be written to disk. However, if desired, the full functionality of the partitioning menu of Solaris' format(1m) is now offered (and even more). . When editing the label, do not loop around edit_label() where a new template file is generated for each turn, this used to be annoying in that any possible syntax error caused a complaint, but then the template was created anew, so the user had to perform all their editing again. Rather loop inside edit_label(), similar to bsdlabel(8), so in case of errors, the user will be presented their previous template file again. . If VTOC-style elements are present, the overlap checks are made less stringent. Overlaps will still be warned about, but overlaps of `unmountable' partitions against other ones are no longer fatal. That way, e. g. VxVM encapsulated disk labels can be fully edited in FreeBSD (but not in Solaris ;-). . In print_label(), generate the editing hints only if the -e flag is in effect. Additionally, print a hint about the total number of sectors in the (hardware) medium. . When editing a label, allow for changing the geometry emulation (and textual name) by modifying the "text:" line on top. That way, a more effective emulation can be chosen. . When editing/reading a label, additionally allow for the suffixes `s' (512-byte sectors), and `c' (cylinders) in the partition size field. . Finally, turn the stub man page into something that really explains the entire thing.

Major overhaul of sunlabel(8). . Implement option -c, all partition sizes will be calculated in cylinders as opposed to sectors. Since the Sun label is inherently cylinder-based, this makes the job a little easier. . Implement option -h, print the label in `human readable' size/offset format. . Implement SVR4-compatible VTOC-style elements. They are fully optional, defaulting to the current behaviour where no VTOC-style table will be written to disk. However, if desired, the full functionality of the partitioning menu of Solaris' format(1m) is now offered (and even more). . When editing the label, do not loop around edit_label() where a new template file is generated for each turn, this used to be annoying in that any possible syntax error caused a complaint, but then the template was created anew, so the user had to perform all their editing again. Rather loop inside edit_label(), similar to bsdlabel(8), so in case of errors, the user will be presented their previous template file again. . If VTOC-style elements are present, the overlap checks are made less stringent. Overlaps will still be warned about, but overlaps of `unmountable' partitions against other ones are no longer fatal. That way, e. g. VxVM encapsulated disk labels can be fully edited in FreeBSD (but not in Solaris ;-). . In print_label(), generate the editing hints only if the -e flag is in effect. Additionally, print a hint about the total number of sectors in the (hardware) medium. . When editing a label, allow for changing the geometry emulation (and textual name) by modifying the "text:" line on top. That way, a more effective emulation can be chosen. . When editing/reading a label, additionally allow for the suffixes `s' (512-byte sectors), and `c' (cylinders) in the partition size field. . Finally, turn the stub man page into something that really explains the entire thing.

Add sunlabel, a more or less drop in replacement for bsd^H^H^Hdisklabel(8) which works on sun labels. Due to the lack of an interface other than write(2) to update labels, it cannot modify an open partition.
