PR/57889: Ricardo Branco: ext2fs does not have user immutable and append
file flags, only system ones. Restrict those to the superuser. Before
the behavior was controlled by EXT2FS_SYSTEM_FLAGS. Make that behavior the
default.

UFS/LFS dirhash:
- Enable UFS_DIRHASH if the architecture or kernel model specific config
file can use 128MB of RAM or more.
- Remove experimental tag from UFS_DIRHASH; it's been with RUMP kernel
and by a number of NetBSD developers for years.
- Add LFS_DIRHASH if LFS was enabled.
- Be somewhat consistent with FS options order.

Remove uscanner(4) driver

This exists for compatibility with a Linux interface which was apparently
deprecated in Linux 2.6. There are various mailing list threads going
back to 2004 where the usefulness of this driver is discussed, but
the conclusion is that scanner software has all moved to using ugen(4)
instead, and enabling this driver will not help you scan things.

Remove uyap, USB YAP phone firmware loader.

And the associated ezload EZ-USB code, which is only used by uyap.
It could theoretically be used by other drivers, but none of them are
in tree.

I suspect that this device isn't in use, as phone technology has improved
a lot since 2001 when uyap(4) was added to the tree.

Proposed with no objections on netbsd-users on 13 April 2020

remove urio(4), a driver for the Rio500 MP3 player.

At this point it is highly unlikely this 1999 device still has users,
but it still comes up in the context of maxv's USB-fuzzing (and any device
could pretend to be a urio(4)), so it's best to get rid of it.

Renamed all major entries to obsolete, as was done in previous removals.

This still requires an update to sanitizers, but they're located in
"external", perhaps it should be first committed upstream?

Proposed on tech-kern a month ago.

Retire "le* at pci?" from the shipped kernel configs:
- If the config had both an le@pci and a pcn, simply remove le@pci
(pcn would match at a higher priority anyway).
- If the config had le@pci enabled, but no pcn, change le@pci to pcn.
- If the config had le@pci commented out, but no pcn, change le@pci
to pcn and leave it commented out.

The pcn driver supports more chips than le@pci and does DMA directly
to/from mbufs rather than memory copies.

Remove FDDI support.

Remove HIPPI support and the esh(4) driver that uses it. There have not
been any users of HIPPI for some time, and it is unlikely to be resurrected.

Enable BUFQ_PRIOCSCAN, CARP, Veriexec by default in GENERIC kernel configs.
On ports without a GENERIC kernel config enable in individul files, e.g evbmips.
Omit on:
atari, dreamcast, emips, epoc32, evbppc/VIRTEX*, ia64, luna68x, mvme68k,
mvmeppc, playstation2, riscv, sun2, sun3, x68k, zaurus due to resource
constraints or port infancy.

Add drvctl to kernel which has audio device.
audiocfg(1) requires drvctl(4).

Add ure(4) to kernel config files. Also add PHY drivers where necessary.

Remove references to "lmc" in the kernel configurations.

remove the 'wd* at umass?' for the non-standardized and rare (extinct?)
In-System Design ATA protocol over Bulk-Only devices from most kernels,
leave only in i386/amd64 ALL; it's unmaintained and likely currently broken,
lack of test hardware makes it impossible to support

Retire the 'midway' driver. Discussed on tech-net@ recently and also three
years ago, part of removing the network ATM code.

Add (commented out) mue(4) to where appropriate.
Also add MII/PHY drivers for USB NICs if missing.

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: 1.42.2; 1.42.4;
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.

Disable uscanner in all kernel configs

As discussed on current-users@, SANE uses ugen via libusb and not
uscanner, so users are not well served by having uscanner. Consensus
is that addressing how to adjust permissions for scanners should not
block restoring basic functionionality.

(Compile-tested only, but there are multiple reports of this being the
right approach.)

branches: 1.35.2;
Fix builds.

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.

Reorganize symbol table embedding. The existing option SYMTAB_SPACE is
replaced by the make option COPY_SYMTAB set to any value. The copy of
the symbol table is no longer put into a buffer in kern_ksyms.o, but a
small helper object. This object is build first with a dummy size, then
the kernel is linked to compute the real dimension of the symbol table
buffer. After that, the helper object is rebuild and the kernel linked
again.

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

LLVM builds have a slightly larger symbol table, so bump the space.

G/C PFIL_HOOKS from the kernel configs.

WABPL is no longer considered experimental (has not been for some time)
so update its comment in config files.

branches: 1.23.2;

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.

Enable COMPAT_50

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.

enable IPFILTER_COMPAT in all kernels that have ipfilter already.
canonicalise several of the ipf option segments in various files
(this mostly means adding commented out IPFILTER_DEFAULT_BLOCK,
or adding commented or uncommented IPFILTER_LOG or IPFILTER_LOOKUP
option statements.)

i built about 20 of these kernels to check, but not all of them.

add uhso(4) device where appropriate
- follow the lead of other USB driver declarations wrt commented out
- (cross-)build tested all these kernels

Remove separate mb_map. The nmbclusters is computed at boot time based
on the amount of physical memory and limited by NMBCLUSTERS if present.
Architectures without direct mapping also limit it based on the kmem_map
size, which is used as backing store. On i386 and ARM, the maximum KVA
used for mbuf clusters is limited to 64MB by default.

The old default limits and limits based on GATEWAY have been removed.
key_registered_sb_max is hard-wired to a value derived from 2048
clusters.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.
