The free space value in the FSInfo block is merely unitialized when it is
0xffffffff. This fixes a bug found in NetBSD.
It must be noted that we never supported all the checks that NetBSD does
as some of them would cause failures with a freshly created FAT32
from MS-Windows.
While here, bring some space fixes.

partitions of types other than "freebsd-boot" (in particular, "efi").
This allows the removal of some nasty hacks for supporting PowerPC systems,
in particular aliasing freebsd-boot to apple-boot on APM and an IBM-specific
code on MBR.
This changes the installer to use the correct names, which also breaks a
degeneracy in the meaning of "freebsd-boot" that allows the addition
of support for some newer IBM systems that can boot from GPT in addition to
MBR. Since I have no idea how to detect which those systems are, leave
the default on IBM PPC systems as MBR for now.
camcontrol(8) now supports a new 'persist' subcommand that allows users to
issue SCSI PERSISTENT RESERVE IN / OUT commands.
sbin/camcontrol/Makefile:
Add persist.c.
sbin/camcontrol/persist.c:
New persistent reservation support for camcontrol(8).
We have support for all known operation modes for PERSISTENT RESERVE
IN and PERSISTENT RESERVE OUT.
exceptions noted above.
sbin/camcontrol/camcontrol.8:
Document the new 'persist' subcommand.
In the section on the Transport ID (-I) option, explain what
Transport IDs for each protocol should look like. At some point
some of this information could probably get moved off in a
separate man page, either on Transport IDs alone or a man page
documenting the Transport ID parsing code.
Add a number of examples of persistent reservation commands.
Persistent Reservations are complex enough that the average user
probably won't be able to get the commands exactly right by just
reading the man page. These examples show a few basic and
advanced examples of how to use persistent reservations.
sbin/camcontrol/camcontrol.h:
Move the definition for camcontrol_optret here, so we can use it
for the persistent reservation code.
Add a definition for the new scsipersist() function.
sbin/camcontrol/camcontrol.c:
Add 'persist' to the list of subcommands.
Document 'persist' in the help text.
sys/cam/scsi/scsi_all.c:
Add the scsi_persistent_reserve_in() and
scsi_persistent_reserve_out() CCB building functions.
Add a new function, scsi_transportid_sbuf(). This takes a
SCSI Transport ID (documented in SPC-4), and prints it to
an sbuf(9). There are some transports (like ATA, USB, and
SSA) for which there is no transport defined. We need to
come up with a reasonable thing to do if we're presented
with a Transport ID that claims to be for one of those
protocols.
Add new routines scsi_get_nv() and scsi_nv_to_str().
These functions do a table lookup to go between a string and an
integer. There are lots of table lookups needed in the
persistent reservation code in camcontrol(8).
Add a new function, scsi_parse_transportid(), along with leaf node
functions to parse:
FC, 1394 and SAS (scsi_parse_transportid_64bit())
iSCSI (scsi_parse_transportid_iscsi())
SPI (scsi_parse_transportid_spi())
RDMA (scsi_parse_transportid_rdma())
PCIe (scsi_parse_transportid_sop())
Transport IDs. Given a string with the general form proto,id these
functions create a SCSI Transport ID structure.
sys/cam/scsi/scsi_all.h:
Update the various persistent reservation data structures to
SPC4r36l, but also rename some fields that were previously
obsolete with the proper names from older SCSI specs. This
allows using older, obsolete persistent reservation types when
desired.
Add function prototypes for the new persistent reservation CCB
building functions.
Add a data strucure for the READ FULL STATUS service action
of the PERSISTENT RESERVE IN command.
Add Transport ID structures for all protocols described in SPC-4.
Add a new series of SCSI_PROTO_XXX definitions, and
redefine other defines in terms of these new definitions.
Add a prototype for scsi_transportid_sbuf().
Change a couple of "obsolete" persistent reservation data
structure fields into something more meaningful, based on
what the field was called when it was defined in the spec.
(e.g. SPC, SPC-2, etc.)
Create a new define, SPRI_MAX_LEN, for the maximum allocation
length allowed for the PERSISTENT RESERVE IN command.
Add data structures and enumerations for the new name/value
translation functions.
Add data structures for SCSI over PCIe Routing IDs.
Bring the PERSISTENT RESERVE OUT Register and Move parameter list
structure (struct scsi_per_res_out_parms) up to date with SPC-4.
Add a data structure for the transport IDs that can optionally be
appended to the basic PERSISTENT RESERVE OUT parameter list.
Move SCSI protocol macro definitions out of the VPD page 0x83
definition and combine them with the more up to date protocol
definitions higher in the file.
Add function prototypes for scsi_nv_to_str(), scsi_get_nv(),
scsi_parse_transportid_64bit(), scsi_parse_transportid_spi(),
scsi_parse_transportid_rdma(), scsi_parse_transportid_iscsi(),
scsi_parse_transportid_sop(), and scsi_parse_transportid().

This partitioning scheme is used in DragonFlyBSD. It is similar to
BSD disklabel, but has the following improvements:
* metadata has own dedicated place and isn't accessible through partitions;
* all offsets are 64-bit;
* supports 16 partitions by default (has reserved place for more);
* has reserved place for backup label (but not yet implemented);
* has UUIDs for partitions and partition types;

This is currently an opt-in build flag. Once ASLR support is ready and stable
it should changed to opt-out and be enabled by default along with ASLR.
Each application Makefile uses opt-out to ensure that ASLR will be enabled by
default in new directories when the system is compiled with PIE/ASLR. [2]
Mark known build failures as NO_PIE for now.
The only known runtime failure was rtld.

Add `flags` u16 field to the hole in ipfw_table_xentry structure.
Kernel has been guessing address family for supplied record based
on xent length size.
Userland, however, has been getting fixed-size ipfw_table_xentry structures
guessing address family by checking address by IN6_IS_ADDR_V4COMPAT().
Fix this behavior by providing specific IPFW_TCF_INET flag for IPv4 records.

Since radix has been ignoring sa_family in passed sockaddrs,
no one ever has bothered filling valid sa_family in netmasks.
Additionally, radix adjusts sa_len field in every netmask not to
compare zero bytes at all.
This leads us to rt_mask with sa_family of AF_UNSPEC (-1) and
arbitrary sa_len field (0 for default route, for example).
However, rtsock have been passing that rt_mask intact for ages,
requiring all rtsock consumers to make ther own local hacks.
We even have unfixed on in base:
do `route -n monitor` in one window and issue `route -n get addr`
for some directly-connected address. You will probably see the following:

option to a selected number of Makefiles, which can greatly speed up the
build on multi-core machines, when using make -j.
This can be extended to more Makefiles later on, whenever they are
verified to work correctly with parallel building.
I tested this on a 24-core machine, with make -j48 buildworld (N = 6):

E.g. the build was approximately 45% faster in real time. On machines
with less cores, or with lower -j settings, the speedup will not be as
impressive. But at least you can now almost max out a machine with
