Keyword substitution: kv
Default branch: MAIN

Fix destroying and moving GPT header also for truncated/extended
images.

Whitespace

Add -H flag to ignore existing MBR (Hybrid MBR/GPT mode).

Mostly merge changes from HEAD upto 20200411

Add rcsid

Add gpt_change_hdr() similar to gpt_change_ent() for changing
arbitrary header fields.

Add a third argument to the "cfn" function that is an argument to
gpt_change_ent().  The purpose of the third argument is to specify
whether the entry to be changed is a primary GPT entry or a secondary
GPT entry.  It is assumed that a secondary GPT entry will always
follow a corresponding primary entry.

This is in preparation for an upcoming change that will require it.

Not all things that write to the disk do something that dk(4) will
be interested in.  Let individual commands decide if ioctl(DIOCMWEDGES)
should be done.  I was conservative and set the flag on any command
that might create/modify/delete partitions in any way.

Fix resizedisk.

fix typo

WARNS=6

refactor the utf code so that it does not leak memory.

merge command line parsers and check all memory allocations.

refactor more duplicated code.

Refactor the command dispatching and help printing logic.

Firs step of refactoring, remove all globals, factor out some common code,
handle alternate usage but not advertise it.

- automatically sync the wedge information unless -n is specified.
- document the general options in the traditional way.
- split the main program into a separate file.

Remove getdisksize support; we either have the ioctls (current/-7) or we
don't (non-netbsd-current/7+tools).

merge the create errors in one place and fix them.

Add a "header" subcommand that displays information about the size of
the disk along with information from the GPT header if it exists.

- record the sector size of the disk
- correct confusion with end_cylinder and end_sector in MBRs
--
- dump all partitions, not just ones that are in use
- while here, squash a memory leak
     It shouldn't be necessary to backup unused partitions, however
the partition GUID is created at the time the GPT is created and
is never changed.  It shouldn't matter if the GUID of an unused
partition changes, but there may be some special case where it
does.  Since it isn't a big deal to record the unused partitions,
might as well do it.
--
Initial cut of gpt restore.  This functions correctly in testing,
but isn't all that pretty.  It has minimal error testing and may
leak memory.  It also only works with empty disks.  If passed "-F"
flag, it will blank the disk for you.
--
document the new restore subcommand
--
- make gpt_gpt() available for use directly by subcommands
- create new resizedisk disk subcommand for relocating backup GPT
--
Fix compile error observed on i386. Use PRIu64.
--
no C99isms in tool code
--
- handle a GPT that isn't an exact multiple of a sector
- adjust PMBR size, in case new disk is a different size
- don't leak as much memory
- clean up error handling somewhat

include <sys/endian.h> for both the non-tools build,
and the tools build on a host where the file exists.
Fixes a build problem on FreeBSD, reported by Herbert J. Skuhra, where
tools/compat's configure detected that be32dec() and friends were
available in the host's <sys/endian.h>, so tools/compat did not provide
its own versions.

Make gpt(8) generate v4 (random) uuids.
Don't needlessly leak your date/time and MAC address when you edit
the disk.
Read from /dev/urandom rather than calling arc4random or anything,
since this is a tool.  (Cygwin seems to have /dev/urandom, but yell
if this breaks the build on your exotic platform because it lacks
/dev/urandom.)

PR/44218 - David Young -- add "type" subcommand to change a partition type

- make gpt_gpt() available for use directly by subcommands
- create new resizedisk disk subcommand for relocating backup GPT

Rebase to HEAD as of a few days ago.

Add restore subcommand.

XXX It does not actually work yet.  It is being committed now to make
later pullups easier.

sync with head.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

Add the backup subcommand.  It dumps the contents of the partition
tables as a plist, which is readable by the restore subcommand.

XXX restore subcommand forthcoming

Add two new subcommands, "set" and "unset".  These were inspired by
FreeBSD's gpart(8), but the code is all mine.  The purpose of these
is to set and unset partition attributes.

Remove FreeBSD specific code as per message to tech-userlevel.

Add a resize command.  This command was inspired by FreeBSD's gpart(8),
but the code was written by myself.

resync from head

Clean up gpt(8) a bit more

uuid_create_nil(3) and uuid_is_nil(3) take a uuid_t*, not a pointer to
an array of bytes merely casted to compatible type.

Additonally, there no need for extra casts and address-of operations when
using le_uuid_*() functions.

Furthermore, le_uuid_*() are identical to uuid_*_le functions in
libc/libuuid, so use those instead on NetBSD.

Support booting from GPT-partioned disks on PC-BIOS-compatible systems.

Much of the work in this commit was done by Mike Volokhov during GSoC 2009.

Let 'gpt add' suggest a collect device name so that opendisk(3) called by
dkctl(8) succeeds.
