This commit was manufactured to restore the state of the 5.2-RELEASE image. Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs. Declare crc32 static.

This also applies to MBR slices for non-GPT disks. Since most of the GPT handling is conditionally compiled, do the same with the partition naming. This fixes a braino that caused slices to be named as GPT partitions and generally messing up an install. Pointy hat: marcel o Save a copy of the GPT entries for which there's a chunk with an 2003-11-04T03:49:01Z Marcel Moolenaar marcel@FreeBSD.org 2003-11-04T03:49:01Z urn:sha1:a9eccd0273392c96ab46827c735b2856403d257f index referencing it. We need to know the original type and name so that we know what to put in the table when we reconstruct it. o Clear the table entries before we rebuild it to avoid that we end up with stale data. o Sequentially populate the table entries from the chunks. For the chunks that have an index (now referencing the saved copy) we use the saved type and name. This way we can handle unknown types better. In all cases we update the start and end LBAs. Don't divide the start and end of the chunk by the sector size when 2003-11-03T06:52:30Z Marcel Moolenaar marcel@FreeBSD.org 2003-11-03T06:52:30Z urn:sha1:b6733aeb6821b7fc9d1f957c6a9ecb2ad3c3cd8c filling in the GPT entry. Both are already in sector numbers (LBA) and exactly what we need for the entry. We now write a structurally correct GPT partitioning.

The first appears to be a typo and instead of dividing the media size with the sector size, we multiplied. The second is an off-by-1 error that's the result of mixing up count and index. The code in question is only applicable for virgin disks and is used to create the "whole" chunk, which covers only the GPT usable portion of the disk. Rewrite Write_Disk() so that it creates a GPT.

I need to free up a disk before I give it a spin. Turn Write_Disk() into a stub for now.

We need to know more than GEOM can provide us so we're forced to read from the disk. Move uuid_type() to open_ia64_disk.c and remove all references on non-ia64. o Pass the GEOM conftxt to Int_Open_Disk() so that only Open_Disk() needs to know about GEOM and libdisk can more easily be used with media not handled by GEOM. o Create an ia64 specific definiton of struct disk on ia64, because we don't need/have most of the fields other platforms need and other fields not applicable on platforms other than ia64. o Do not compile change.c on ia64. It's too PC specific. o In Fixup_Names() in create_chunk.c, try all partition numbers that are valid for the GPT disk. We have the total number of partitions that can be allocated in the disk structure on ia64. Also, use the GPT partition naming if we're creating one under a chunk of type "whole". It's a GPT partition in that case. o In Create_Chunk(), compile-out the PC specific code on ia64 that checks BIOS geometry restrictions. o In Debug_Disk() in disk.c, dump the ia64 specific fields. o Save the partition index in the chunk on ia64 so that we can preserve it when we write the data back to disk. This avoids that partitions get moved around or swapped after installing FreeBSD, which may render a disk unusable. Do not fill in d_ncylinders, d_ntracks and d_nsectors in the disklabel 2003-11-02T08:07:25Z Marcel Moolenaar marcel@FreeBSD.org 2003-11-02T08:07:25Z urn:sha1:78cb7a7cd056161d24214f5912afb6b943a8892e on ia64. Not only do we not have a disklabel by default, we also do not have a notion of cylinders, tracks and sectors.
