Unreference IPF/PF from all the config files, and enable NPF instead when
wanted. This also fixes some inconsistencies I saw in several files (eg
IPF options while IPF was not compiled, IPF+PF enabled by default, etc).

branches: 1.62.2;
disable a few more things and return another 1% of memory.

branches: 1.61.2;
clean up COMPAT_* options for native netbsd code:
- new series of files that are useful for saying "i want everything
since netbsd 1.4", etc.
- use the fact COMPAT_* options have future dependancies to remove
many redundant options.

removes about 3000 lines total across kernel configuration files.
tested about 30 random kernels in the changed list.

Remove TCP_COMPAT_42 from the config files. Pass 3.

Remove KMEMSTATS.

branches: 1.58.2;
Systematize (and in many cases, fix) the comments on options COMPAT_NN.

There are quite a few configs that are missing some COMPAT_NN options
in ways that don't make sense; this should probably get cleaned up
too, but for the time being I've not added or removed anything.

Add "options COMPAT_70" to all kernel configuration files that
already had "options COMPAT_60".

Comment out options and devices to sync GENERIC rev 1.90.

branches: 1.55.4;
G/C PFIL_HOOKS from the kernel configs.

branches: 1.54.2;
remove obsolete networking options

the bogus number police

remove confusing numeric locators where they are unused.

Under FAST_IPSEC, IPSEC_ESP is mandatory; GC it.

Retire OSI network stack. OK core@

branches: 1.49.8;

The rnd pseudo-device is not really optional, because it is in the same
source file as the entropy-pool code itself. Move it to std. This
will be cleaned up more when I split the sources up as they should be.

This fixes build breaks on several ports. Thanks to Havard Eidnes for
pointing them out.

branches: 1.48.2;
dependant -> dependent

merge the bouyer-quota2 branch. This adds a new on-disk format
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

for details.

Remove unused count from pseudo-device md.

Remove unused count (invariably "4") from pseudo-device fss.

branches: 1.44.6; 1.44.8;
Remove softdep, pass 1. We are focused on improving journalling.

Proposed on tech-kern@.

Remove LKMs and switch to the module framework, pass 1.

Proposed on tech-kern@.

branches: 1.42.2; 1.42.8; 1.42.10;
Remove obsolete options SHMMAXPGS.

branches: 1.41.2;
Always specify COPTS="-Os" and disable several options and devices
to shrink kernels. Current sun68k bootloader can't load a kernel larger
than ~2MB, and our ever growing kernel have reached the limit.

branches: 1.40.6;
- add options COMPAT_40
- adjust comments

branches: 1.39.24; 1.39.30; 1.39.36;
update comments on NFS_V2_ONLY after nqnfs removal. no functional changes.
from Arnaud Lacombe.

Add "options NFS_RSIZE=1024,NFS_WSIZE=1024" for poor ec(4) interfaces.

Remove "rnd is EXPERIMENTAL" comments and enable pseudo-device rnd.

Don't specify number of ptys unless it's smaller than default 16.

remove MALLOC_NOINLINE, it doesn't do anything anymore.

branches: 1.34.2; 1.34.4;
PR/34283: Gene ENonymous: Add IPFILTER_LOOKUP to the default kernel options
Also remove CCITT,NS,NIP

branches: 1.33.2;
Remove 'count' argument for pseudo-devices that ignore it
(vnd, bpfilter, ppp, gif, gre, tun, sl, strip, faith, stf).

bpfilter doesn't accept count anymore.

branches: 1.31.2; 1.31.4; 1.31.6;
Remove obsolete options VNODE_OP_NOINLINE.

Adjust comments for options FFS_NO_SNAPSHOT.

XXX: This option should be mentioned in options(4).

typo in comment.

Enable ptyfs by default on the non-install and non small/tiny/ramdisk kernels

64 bit inode changes.

revert "defflag VMSWAP" changes for now.
there seems to be far more people who don't want to edit
their kernel config files than i thought.

add "options VMSWAP" to non INSTALL kernels.

Add (commented out) IPSEC_NAT_T option.

branches: 1.23.2; 1.23.4;
Add COMPAT_20 (and COMPAT_16 in some cases) to kernel config files
that didn't have those options but had other earlier compat options.

Invert FFS_SNAPSHOT to FFS_NO_SNAPSHOT

Add 'option FFS_SNAPSHOT' to most of the config files.
Commented out for kernels that appear to hace space constraints.

Add file system snapshots to kernel configs.

- Ffs internal snapshots get compiled in unconditionally.

- File system snapshot device fss(4) added to all kernel configs that
have a disk. Device is commented out on all non-GENERIC kernels.

branches: 1.19.4; 1.19.6;
Add COMPAT_BSDPTY to the rest of the config files.

Add "options SYSCTL_INCLUDE_DESCR" to a lot of configs, but commented
out in most of them.

branches: 1.17.2;
Add COMPAT_16.

Bye Bye UCONSOLE

enable USERCONF by default; it's small and extremely useful to have available.

PIPE_SOCKETPAIR, MALLOC_NOINLINE and VNODE_OP_NOINLINE are all appropriate for
the 'minimal memory' configurations.

Enable "pseudo-device clockctl" in all kernels, except
installation related kernels (INSTALL* and RAMDISK*).
This enables rc.conf(5) $ntpd_chroot to be used "out of the box"

branches: 1.12.2; 1.12.4;
Add the INCLUDE_CONFIG_FILE option to all config files. In config
files that are generic (ie, GENERIC, GENERICSBC, GENERIC32, ALL, or
ALPHA), it is uncommented.

Add commented-out USERCONF option. Mainly useful for install media
and can be optionally enabled based on miniroot and ramdisk size
requirements.

add options PIPE_SOCKETPAIR to individual kernel configs
the option is commented out on everything but kernels I was able
to recognize as INSTALL-like or ones for small memory machines

In kernel config files, now mention the options SCSI_OLD_NOINQUIRY,
NFS_V2_ONLY, and VNODE_OP_NOINLINE, commented out as appropriate
for each configuration.
Convert to use genassym.cf and genassym.sh, as other ports do.

Disabled some more things that lighter kernels don't need,
and picked up some formatting fixes from GENERIC.

cleanup:
options SPACE TAB
makeoptions TAB
psuedo-device TAB
remove trailing whitespace
replace multiple spaces -> tabs
options "FOO" -> options FOO
options "FOO=bar" -> options FOO=bar
options "FOO=\"bar\"" -> options FOO="\"bar\""

- pull in opt_kgdb.h where necessary
- replace opt_kgdb_machdep.h with opt_kgdb.h
- defparam opt_kgdb.h:
KGDB_DEV KGDB_DEVNAME KGDB_DEVADDR KGDB_DEVRATE KGDB_DEVMODE
- move from opt_ddbparam.h to opt_ddb.h:
DDB_FROMCONSOLE DDB_ONPANIC DDB_HISTORY_SIZE DDB_BREAK_CHAR SYMTAB_SPACE
- replace KGDBDEV with KGDB_DEV
- replace KGDBADDR with KGDB_DEVADDR
- replace KGDBMODE with KGDB_DEVMODE
- replace KGDBRATE with KGDB_DEVRATE
- use `9600' instead of `0x2580' for 9600 baud rate
- use correct quotes for options KGDB_DEVNAME="\"com\""
- use correct quotes for options KGDB_DEV="17*256+0"
- remove unnecessary dependancy on Makefile for kgdb_stub.o
- minor whitespace cleanup

Standardise TCP_COMPAT_42 as commented out, grouped with other COMPAT options,
and with the comment '4.2BSD TCP/IP bug compat. Not recommended'
Add commented out 'TCP_DEBUG # Record last TCP_NDEBUG packets with SO_DEBUG'
(All hail amiga and atari which make some attempt to automate the
multiplicity of config files...)

Updated with VME machine support, a.out compat,
some zs and console changes.

Fix various misspellings of compatible/compatibility.

branches: 1.2.2;
Trimmed off some options that are unnecessary for now,
and some that don't work. Added some more comments,
commented out some 2/50 device entries.
