1.75	03-Jun-2023	lukem	bsd.own.mk: rename GCC_NO_* to CC_WNO_* Rename compiler-warning-disable variables from GCC_NO_warning to CC_WNO_warning where warning is the full warning name as used by the compiler. GCC_NO_IMPLICIT_FALLTHRU is CC_WNO_IMPLICIT_FALLTHROUGH Using the convention CC_compilerflag, where compilerflag is based on the full compiler flag name.
1.74	13-Oct-2019	mrg	introduce some common variables for use in GCC warning disables: GCC_NO_FORMAT_TRUNCATION -Wno-format-truncation (GCC 7/8) GCC_NO_STRINGOP_TRUNCATION -Wno-stringop-truncation (GCC 8) GCC_NO_STRINGOP_OVERFLOW -Wno-stringop-overflow (GCC 8) GCC_NO_CAST_FUNCTION_TYPE -Wno-cast-function-type (GCC 8) use these to turn off warnings for most GCC-8 complaints. many of these are false positives, most of the real bugs are already commited, or are yet to come. we plan to introduce versions of (some?) of these that use the "-Wno-error=" form, which still displays the warnings but does not make it an error, and all of the above will be re-considered as either being "fix me" (warning still displayed) or "warning is wrong."
1.73	24-Jan-2018	skrll	branches: 1.73.4; Remove port-acorn26 OK core@
1.72	31-Jan-2016	christos	fix broken patch
1.71	31-Jan-2016	christos	PR/50729: Izumi Tsutsui: Add "SMALLPROG"-like options to disklabel(8)
1.70	03-May-2013	matt	Make disklabel a MI tool. It will use MACHINE/MACHINE_ARCH to determine the disklabel params as well as allowing command-line options of -M <machine> and -B {le,be} to specify MACHINE and byteorder to be used.
1.69	30-Aug-2011	bouyer	branches: 1.69.2; 1.69.8; Add getlabelusesmbr(), as proposed in http://mail-index.netbsd.org/tech-userlevel/2011/08/25/msg005404.html This is used by disk tools such as disklabel(8) to dynamically decide is the undelyling platform uses a disklabel-in-mbr-partition or not (instead of using a compile-time list of ports). getlabelusesmbr() reads the sysctl kern.labelusesmbr, takes its value from the machdep #define LABELUSESMBR. For evbmips, make LABELUSESMBR 1 if the platform uses pmon as bootloader, and 0 (the previous value) otherwise.
1.68	18-Aug-2011	phx	Define USE_MBR for ofppc.
1.67	12-Feb-2011	dholland	Disable COMPAT_386BSD_MBRPART. The code is still here if anyone needs it for some reason. (But I have no idea why that would be -- if you have one of these really ancient partitions and you're about to run disklabel, you can easily run fdisk first and change the partition type to NetBSD.) As it stands, the code will munch FreeBSD installs under some circumstances, which is really not acceptable behavior. The code, along with the kernel support that's been disabled by default for several years, and some related but less dangerous code in sysinst, should prboably be removed entirely after -6 is branched. Discussed on tech-kern and tech-userlevel; closes PR 44496. This is also almost certainly the cause of PR 42521 and PR 38841.
1.66	13-Dec-2009	nakayama	branches: 1.66.2; System utilities, boot programs and kernel modules are machine (port) specific not CPU, so use MACHINE not MACHINE_ARCH.
1.65	05-Dec-2009	pooka	Remove support for NetBSD/playstation2.
1.64	28-Nov-2009	tsutsui	Don't use #ifdef __${MACHINE_ARCH}__ to enable machine dependent features. Instead, use proper macro defined in Makefile per ${MACHINE_ARCH}. __${MACHINE_ARCH}__ doesn't represent an architecture of tool's target but an architecture of binaries being compiled, so required features are not prolery enabled or unintentionally enabled on certain host and target combinations during src/tools build.
1.63	28-Nov-2009	tsutsui	Make dreamcast, evbsh3, and mmeye use -DUSE_MBR. All of these ports use src/sys/arch/sh3/sh3/disksubr.c which is MBR aware.
1.62	14-Feb-2009	abs	Convert more MACHINE tests to MACHINE_ARCH
1.61	11-Mar-2008	aymeric	branches: 1.61.6; 1.61.8; The hpcsh kernel does for sure USE_MBR. Make disklabel use it too on hpcsh. With this, it is possible to bootstrap a MBR partitioned CF card without partitioning and disklabelling it first on another platform.
1.60	18-Dec-2006	nonaka	branches: 1.60.4; 1.60.10; 1.60.12; zaurus use MBR partition info.
1.59	01-Sep-2006	uwe	New NetBSD/landisk port uses MBR too.
1.58	19-Oct-2005	dsl	Rototil the way disklabel -r reads and writes labels. In particular the 'read' part plays 'hunt the disklabel' in order to get a label into a local buffer - from where it can be displayed/edited. The 'write' part makes a separate scan of the disk looking for places to write the label. The main changes are: - It can no longer write the first 8k of the mbr to the pbr (or v.v.) - All labels on the disk (that it can find) get updated during a write - With -A all the labels are displayed (inc. those deleted by -D) - Addition of -D which will delete (by one's complimenting dk_magic{2}) and existing labels before writing labels to the expected locations. - -v gives some verbose output to stderr, -vv more etc A better basis for processing incorrect endian labels, or labels from other architectures.
1.57	23-Jun-2005	fvdl	If HOSTPROG is empty, do not pull in libutil, since we do not need it in that case, and several host platforms do not have libutil. Fixes the build of these programs as host tools on platforms without libutil.
1.56	17-Jun-2005	dsl	Rip out the support for writing bootstrap code. installboot(8) contains support for hp300, hp700 and vax, $MACHINE is never arm32. Fix usage output to only contain progname() once - bug introduced in rev 1.89
1.55	12-Jun-2005	dyoung	Make disklabel(8) into a host-tool, "nbdisklabel." Move disklabel.c to main.c to avoid a name collision with lib/libc/gen/disklabel.c when we build nbdisklabel. Still todo: commit host-tool build infrastructure to src/tools/disklabel/.
1.54	20-Jan-2005	xtraeme	WARNS=2 is the default defined in sbin/Makefile.inc. (thanks wiz)
1.53	20-Jan-2005	xtraeme	WARNS=2
1.52	13-Oct-2004	gavan	Initial import of iyonix port. The Iyonix is a desktop machine from Castle Technology, based on a 600MHz XScale[tm] 80321 processor. * Uses the bootloader from NetBSD/acorn32, which is now 32-bit compatible. * Currently boots multiuser with a serial console. * Device support is not yet complete. With help from abs.
1.51	28-Jun-2004	jkunz	Add hp700 MD options for proper boot code handling.
1.50	18-Jan-2004	lukem	* Enable SAVEBOOTAREA on i386 and amd64 (by merging the Makefile controls with the section for the other MBR-using platforms that already enable this) * Don't prompt the user to "erase the previous contents of the disk" when there's no NetBSD MBR partition; SAVEBOOTAREA is sufficient. These fixes mean that you can create a disklabel (on an i386/amd64) on a disk that doesn't have a NetBSD MBR partition without trashing the existing MBR. The previous behaviour was extremely annoying when working with media such as FAT-formatted CF cards, and didn't really protect people with such from accidentally trashing part of sector 1 of such disks, and made it extremely easy to trash sectors 0..15 of those disks instead.
1.49	10-Nov-2003	fvdl	Bring back disklabel -B for now, since hp300 installboot isn't ready for prime time yet.
1.48	08-Nov-2003	dsl	Rip out all the '-B bootblock' support, everything should use installboot(8). (can only affect arm32, hp300 and vax ports, and doesn't affect sysinst).
1.47	02-Nov-2003	shin	playstation2 needs MBR support in disklabel(8).
1.46	26-Apr-2003	fvdl	x86_64 -> amd64
1.45	11-Dec-2002	fvdl	Handle MBRs for x86_64.
1.44	28-Jul-2002	manu	Enable USE_MBR for all arm ports.
1.43	18-Jun-2002	itojun	USE_MBR on macppc too
1.42	24-Mar-2002	bjh21	Rename arm26 -> acorn26.
1.41	29-Nov-2001	bjh21	Rather than making FileCore boot block support conditional on __arm32__, make it conditional on USE_ACORN, and define that if MACHINE is arm26 or acorn32. This is less than optimal, and maybe we should define it for all ARM systems, but then disklabel handling across architectures is generally a mess at the moment.
1.40	19-Nov-2001	minoura	Preserve the boot area on x68k.
1.39	24-Dec-2000	lukem	move showinfo() and showpartition() into separate file, for use by other programs. slightly change argument signature so that globals aren't depended upon.
1.38	02-May-2000	soren	branches: 1.38.4; MBR on cobalt too.
1.37	02-May-2000	nonaka	also use mbr partition table on prep.
1.36	31-Jan-2000	soda	- use MBR partition table also on arc. - use defined(USE_MBR) instead of defined(__i386__), like hpcmips and arc.
1.35	09-Jan-2000	shin	Add '-DSAVEBOOTAREA' to keep MBR partition information when NetBSD partition starts at sector 0. Closes PR:port-hpcmips/9146.
1.34	11-Oct-1999	shin	add hpcmips support (MBR)
1.33	03-Jun-1999	cgd	branches: 1.33.2; On NetBSD/alpha, go out of the way to read the boot area's contents if -r is specified, so that the boot blocks aren't clobbered when writing labels.
1.32	09-Apr-1999	kleink	Update a pasto-ed comment.
1.31	21-Jan-1999	pk	branches: 1.31.2; Enable non-cylinder-aligned partition warning on sparc[64] & sun3. See also PR#6853.
1.30	02-Mar-1998	drochner	Handle new MBR partition ID on i386. Put all code which decides about usability of an entry to one place, use same algorithm as kernel (ie, check signature).
1.29	18-Oct-1997	mark	branches: 1.29.2; Define NUMBOOT=1 for the arm32 port.

1.19	08-Mar-1997	christos	Add -i (interactive mode to create/edit labels) inspired by the SunOS/Solaris format/partition command.
1.18	17-Oct-1995	cgd	don't define NUMBOOT on the alpha, any more. boot block installation is now done by /usr/mdec/installboot.
1.17	23-Apr-1995	ragge	Changed to use only one bootblock file on VAX.
1.16	18-Apr-1995	ragge	Added vax for 2-file boot blocks.

1.3	17-Jul-2015	tsutsui	Fix botch in "make disklabel a MI tool" changes in rev 1.2. After that chanage, "MAXPARTITIONS" constant is not for the target port. If host's MAXPARTITIONS is larger than a value of the target label and target endianness is different from the build host, bswaplabel() could overwrite data beyond the disklabel and primary boot stored after LABELSECTOR in images might be corrupted.

If a partition one larger was used it would be dropped from the disklabel with a warning and the label written anyway! The (off by one) check for a bad partition name was against npartitions anyway, rather than MAXPARTITIONS. npartitions was just read from the disklabel and could have been set to an arbitrary value. Given 'disklabel -i' sets npartitions automatically, make the normal case check partition names against MAXPARTITIONS, and if necessary increase npartitions to the size needed to hold the last partition used. While here remove two 'write only' uses of a 'part' variable.

These fixes mean that you can create a disklabel (on an i386/amd64) on a disk that doesn't have a NetBSD MBR partition without trashing the existing MBR. The previous behaviour was extremely annoying when working with media such as FAT-formatted CF cards, and didn't really protect people with such from accidentally trashing part of sector 1 of such disks, and made it extremely easy to trash sectors 0..15 of those disks instead.

Keep the sun3 groveling code to find a NetBSD disklabel in the first sector (so that it can find a label at the old sun3 LABELOFFSET) as a fallback is not label at LABELOFFSET, or sun label is present. - Fix the sun3 LABELOFFSET (was 64, but the kernel wrote the NetBSD label at 128) - Make next68k disksubr.c always write a next-compatible disklabel. - remove #ifdef __sparc__ hack from disklabel(8), and change it to issue a DIOCWDINFO after writing the disklabel to the raw partition in the -r/-I case (so that the kernel can convert the label if needed).

1.119	08-Oct-2003	lukem	Overhaul MBR handling (part 1): <sys/bootblock.h>: * Added definitions for the Master Boot Record (MBR) used by a variety of systems (primarily i386), including the format of the BIOS Parameter Block (BPB). This information was cribbed from a variety of sources including <sys/disklabel_mbr.h> which this is a superset of. As part of this, some data structure elements and #defines were renamed to be more "namespace friendly" and consistent with other bootblocks and MBR documentation. Update all uses of the old names to the new names. <sys/disklabel_mbr.h>: * Deprecated in favor of <sys/bootblock.h> (the latter is more "host tool" friendly). amd64 & i386: * Renamed /usr/mdec/bootxx_dosfs to /usr/mdec/bootxx_msdos, to be consistent with the naming convention of the msdosfs tools. * Removed /usr/mdec/bootxx_ufs, as it's equivalent to bootxx_ffsv1 and it's confusing to have two functionally equivalent bootblocks, especially given that "ufs" has multiple meanings (it could be a synonym for "ffs", or the group of ffs/lfs/ext2fs file systems). * Rework pbr.S (the first sector of bootxx_): + Ensure that BPB (bytes 11..89) and the partition table (bytes 446..509) do not contain code. + Add support for booting from FAT partitions if BOOT_FROM_FAT is defined. (Only set for bootxx_msdos). + Remove "dummy" partition 3; if people want to installboot(8) these to the start of the disk they can use fdisk(8) to create a real MBR partition table... + Compile with TERSE_ERROR so it fits because of the above. Whilst this is less user friendly, I feel it's important to have a valid partition table and BPB in the MBR/PBR. Renamed /usr/mdec/biosboot to /usr/mdec/boot, to be consistent with other platforms. * Enable SUPPORT_DOSFS in /usr/mdec/boot (stage2), so that we can boot off FAT partitions. * Crank version of /usr/mdec/boot to 3.1, and fix some of the other entries in the version file. installboot(8) (i386): * Read the existing MBR of the filesystem and retain the BIOS Parameter Block (BPB) in bytes 11..89 and the MBR partition table in bytes 446..509. (Previously installboot(8) would trash those two sections of the MBR.) mbrlabel(8): * Use sys/lib/libkern/xlat_mbr_fstype.c instead of homegrown code to map the MBR partition type to the NetBSD disklabel type. Test built "make release" for i386, and new bootblocks verified to work (even off FAT!).

1.80	18-Jan-2000	perseant	disklabel now understands the p_sgs partition field (shift to compute segment size from block size). newfs_lfs now reads the disklabel to find segment, block, and fragment sizes. Because reading this info from the wrong fs type could result in very poor fs layout (e.g. ffs has "16" where the segshift would go, resulting in 512-megabyte segments for 8K blocks), newfs_lfs refuses to create a filesystem on a partition not labeled "4.4LFS". Man pages for newfs_lfs updated to reflect this change.

According to disklabel.h, its LFS semantics are "segment shift" (log2(segment size)), but in the code it is used nowhere, and there are even plans to allow non-poweroftwo segment sizes, so it won't ever work. While at this, simplify the disktab-like output routine... here, currently, BSDFFS, BSDLFS, EX2FS and ADOS do the same, so don't duplicate the code.

1.69	03-May-1999	christos	Add a 'chain' command in interactive mode that allows you to vary the size of the partitions, while the starting point gets adjusted automagically. This chaining works for partitions that are not 'unused'.
1.68	30-Apr-1999	abs	STRICT_ALIGNMENT only applies to the start of partitions, not length.
1.67	29-Apr-1999	wrstuden	Fix disklabel -t to work with disks that don't end on a cylinder. Before it wasn't adding a "su" entry, so when the disktab was read, the sectors per unit was initialized to "nc"*"sc" which was wrong. Fixes PR/7446 reported by Matthias Buelow <mkb@altair.mayn.de>.
1.66	26-Apr-1999	abs	Allow partitions to extend to the end of the disk, even when STRICT_CYLINDER_ALIGNMENT defined. This allows existing valid disklabels to work (including those generated by sysinst).
1.65	09-Apr-1999	bouyer	If checklabel() failed, the label has not been written, so exit(1).

1.55	07-Jun-1998	mark	Fix from Chris Demetriou to modify the way in which arm32 filecore checksums are calculated paying attention to the fact that the way the checksum works a sectors filled with a single byte value will always checksum correctly.
1.54	26-Mar-1998	cgd	when reading the MBR, seek to DOSBBSECTOR * DEV_BSIZE rather than just DOSBBSECTOR. DOSBBSECTOR is 0 so it doesn't really matter, but the former is what was really intended.
1.53	26-Mar-1998	cgd	in makebootarea() (if NUMBOOT is nonzero), before reading the contents of the old boot area so that 'disklabel -r -w' won't clobber anything, be sure to seek to the offset of the boot area (like readlabel() does). Otherwise, if the machine has code which looks up machine-dependent label bits, the offset read from will be incorrect, and disklabel will end up secretly replacing the boot area with other data (which probably doesn't look like a boot block). The only port this currently affects is NetBSD/arm32, because it's the only one of the three ports that use NUMBOOT > 0 that has MD label grovelling code.
1.52	25-Mar-1998	cgd	factor out some more common bits into 'confirm', and make it a bit more bullet-proof. also, make the arm32 #ifdefs a bit more consistent with the i386 #ifdefs (without actually changing the behaviour of the code).
1.51	24-Mar-1998	cgd	use warnx when warning about an old BSD partition ID (i386 MBR code), since err/warn seem to be used consistently throughout the code, rather than fprintf.
1.50	24-Mar-1998	cgd	KNF arm32-specific label-grovelling code. Also, clean up error messages (errx instead of err, kill bogus newlines, make error messages look more "normal").
1.49	02-Mar-1998	drochner	Handle new MBR partition ID on i386. Put all code which decides about usability of an entry to one place, use same algorithm as kernel (ie, check signature).

1.45	13-Oct-1997	bouyer	The number of fs types is FSMAXTYPES not DKMAXTYPES. Correct read of formatted file (used with -e or -R) so that fstype with spaces will work. Also enlarge the fstype field by 2 chars so that "Linux Ext2" will not be truncated.

1.34	10-Aug-1996	explorer	Fix disklabel to deal with some syntax errors a little better. Mostly, when someone specifies a partition entry like: c: 1295850 0 or g: 1295850 0 4.2BSD disklabel would dump core. Now it generates a warning like it should in the first case and complains about too few fields in the second. Perhaps I should just default to unused in the first case, but this prevents core dumps. (pr bin/2659)
1.33	10-Aug-1996	explorer	Don't display cylinder comments if the number of cylinders is zero. This closes pr bin/2683.

1.31	29-Jun-1996	pk	Allow display and editing of partition size & offset fields in <cyl/track/sector> format. This format is always accepted on input (`-e' and `-R'); to display it use `-C'.
1.30	14-Mar-1996	ghudson	Include the total number of sectors in the text representation of the label; calculating based on the disk geometry is not always accurate (notably, for SCSI disks). Also be a bit more careful about printing out fixed-width types.

1.9	19-Oct-2005	dsl	Rototil the way disklabel -r reads and writes labels. In particular the 'read' part plays 'hunt the disklabel' in order to get a label into a local buffer - from where it can be displayed/edited. The 'write' part makes a separate scan of the disk looking for places to write the label. The main changes are: - It can no longer write the first 8k of the mbr to the pbr (or v.v.) - All labels on the disk (that it can find) get updated during a write - With -A all the labels are displayed (inc. those deleted by -D) - Addition of -D which will delete (by one's complimenting dk_magic{2}) and existing labels before writing labels to the expected locations. - -v gives some verbose output to stderr, -vv more etc A better basis for processing incorrect endian labels, or labels from other architectures.

In particular the 'read' part plays 'hunt the disklabel' in order to get a label into a local buffer - from where it can be displayed/edited. The 'write' part makes a separate scan of the disk looking for places to write the label. The main changes are: - It can no longer write the first 8k of the mbr to the pbr (or v.v.) - All labels on the disk (that it can find) get updated during a write - With -A all the labels are displayed (inc. those deleted by -D) - Addition of -D which will delete (by one's complimenting dk_magic{2}) and existing labels before writing labels to the expected locations. - -v gives some verbose output to stderr, -vv more etc A better basis for processing incorrect endian labels, or labels from other architectures.

If disklabel(8) was compiled as a host tool, then the defaults still come from the port's LABELOFFSET and LABELSECTOR #defines. Otherwise, the defaults still come from the sysctls, kern.labelsector and kern.labeloffset. This change helps me create a bootable CompactFlash image with both a Master Boot Record (MBR) and a BSD disklabel for the RouterBOARD 153. The RB 153 is an evbmips board with a CompactFlash slot. It searches the MBR on a CompactFlash card for a partition containing an ELF kernel. When disklabel(8) is built for evbmips, it will ordinarily overwrite an MBR with the BSD disklabel.

1.11	28-Feb-2004	dsl	Print everything unsigned - helps a bit for disks with [2^31..2^32) sectors.
1.10	29-Dec-2003	jdc	If a partition is adjusted so that it falls off the end of the disk, display a '+' character (aka the '*'). OK'ed by Christos.
1.9	20-Oct-2003	pooka	Partition size and offset inside the disklabel are unsigned. Print them as unsigned so that we don't print negative values when we're halfway through.
1.8	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22308, verified by myself.
1.7	04-Aug-2003	dsl	Make output fit into 80 columns when a partition doesn't end on a cylinder boundary.
1.6	01-Jul-2003	simonb	Line up the cylinder numbers in the printlabel output a bit better.
1.5	28-Sep-2002	dbj	add FS_APPLEUFS part of PR #17345
1.4	27-May-2002	drochner	display / read the p_cdsession field in the FS_ISO9660 case
1.3	19-Oct-2001	lukem	minor WARNS=2 stuff
1.2	26-May-2001	christos	- KNF printlabel.c - add a function to print only one partition's info. - print the partition information if it was modified in interactive mode. - improve on the chaining code. [still assumes that partition offsets increase monotonically]. We could check for overlap too.
1.1	24-Dec-2000	lukem	branches: 1.1.2; move showinfo() and showpartition() into separate file, for use by other programs. slightly change argument signature so that globals aren't depended upon.
1.1.2.2	26-Feb-2001	he	Pull up revision 1.1 (new, requested by lukem): Several fixes and enhancements: o with ``-I'', initialize the label if it's not there, it's corrupt, or there's no ``fake'' label. o correct partition table header o move some functions into a separate file for other programs to use o fix examples and cross references o various cleanups
1.1.2.1	24-Dec-2000	he	file printlabel.c was added on branch netbsd-1-5 on 2001-02-26 22:25:44 +0000
