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.

vether: Add to kernel configurations

It's only enabled if the kernel enabled bridge AND tap.
Otherwise it's commented out.

Remove references to BRIDGE_IPF, it is now compiled in by default.

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.

Remove the strip(4) - Starmode Radio IP - pseudo-device driver. It is
long since obsolete.

branches: 1.70.6;
Remove references to "lmc" in the kernel configurations.

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

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: 1.67.2;
rename panel to lcdpanel.

rename the cobalt panel to ledpanel to avoid conflict with fdt.

branches: 1.65.2;
Alternate buffer queue strategies no longer considered experimental, update
description.

Discussed on tech-kern
http://mail-index.netbsd.org/tech-kern/2018/01/21/msg023002.html

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.

branches: 1.62.8;
wildcard speaker attachments, now that we can handle many of them.

remove VAUDIOSPEAKER for now, will be done differently.

Add a synthesized pc beeper and keyboard bell for platforms with an audio
device.

branches: 1.59.2;
Add `pseudo-device ksyms' where `options DDB' is used, because
config(1)/config(5) can't handle module dependency correctly at this
moment.

(This is another proof that shared file definition (`file xxx.c a|b')
is a bad idea.)

Remove KMEMSTATS.

branches: 1.57.2;
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 commented out bpfjit options to mips kernels.
While here, add 2 missing RCS ids.

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

branches: 1.54.2;
remove obsolete networking options

more bogus number removal

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: 1.48.2;
P1003_1B_SEMAPHORE is no longer optional.

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

branches: 1.46.2;

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.

branches: 1.45.2;
dependant -> dependent

TAB/space cosmetics.

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.

See http://mail-index.netbsd.org/tech-kern/2011/02/19/msg010025.html
for details.

branches: 1.42.2; 1.42.4;
Remove unused count from pseudo-device md.

branches: 1.41.4;
Remove the portalfs kernel file system driver. Replace mount_portal(8)
with a version based on puffs. User functionality remains the same.

Remove SHMMAXPGS from all kernel configs. Dynamically compute the
initial limit as 1/4 of the physical memory. Ensure the limit is at
least 1024 pages, the old default on most platforms.

branches: 1.39.4;
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@.

- fix (commented out) SBLive! driver name; it's emuxki, not sbl
- add commented out audio* at audiobus? line

Our ever glowing kernel reaches the firmware limit,
so disable several options to shrink the INSTALL kernel that will
be used as an emergency kernel loaded by the firmware directly.

branches: 1.35.2;
Now the cobalt kernel can detect boot device properly by boot strings
passed from the firmware, so change root file system type from
explicit nfs to generic '?' so that the INSTALL kernel can also be used
as a rescue kernel on localdisk.

Add "options WAPBL" to standard GENERIC/INSTALL type configs.

branches: 1.33.4; 1.33.6; 1.33.10;
Add zsc(4) and zstty(4) for Qube 2700.

Enable bpfilter, which is required by dhclient(8).

Comment out some PCIIDE devices which wouldn't be available for a PCI slot.

Enable puc at pci and com at puc, which might be useful Qube2700.

Add options COMPAT_40.

Remove systrace. Ok core@.

branches: 1.27.2; 1.27.28; 1.27.34; 1.27.42; 1.27.46;
Remove options SOSEND_NO_LOAN. Now it's handled in mips/pmap.c.

- Document COMPAT_15 as doing nothing
- Add COMPAT_15 to all the kernel that had COMPAT_14, for the sake of coherency
- Remove the only occurences of #ifdef COMPAT_15 in the tree: for the ARM
ports, COMPAT_15 was always used in conjunction with EXEC_AOUT. Only EXEC_AOUT
matters here.

Add options SOSEND_NO_LOAN. See the following comment for details:
---
# XXX Disable zero-copy page loaning in sosend() temporarily:
# PV mappings created by sosend_loan() in sys/kern/uipc_socket.c may
# produce virtual cache aliases and it seems to cause TLB MISS panic
# in cache flush code called from bus_dmamap_sync(9) PREWRITE ops
# during heavy TX packet traffic on tlp(4).

Disable SYSTRACE by default on all kernels (discussed with core)

Use CPUFLAGS="-march=vr5000 -mabi=32".

According to src/gnu/dist/binutils/gas/config/tc-mips.c
and src/gnu/dist/gcc/gcc/config/mips/mips.c,
CPUFLAGS="-mips2 -mtune=vr5000" is enough even for Rm523x CPUs.

Specify CPUFLAGS for Rm523x:

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.

Adjust comments for options FFS_NO_SNAPSHOT.

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

swcr -> swcrypto

"pseudo-device crypto" really refers to the /dev/crypto API to the
opencrypto framework, not the framework itself. Update the comment
accordingly.

Add "pseudo-device swcr" (commented out if "pseudo-device crypto" is also
commented out).

- use -mmemcpy (it saves ~12kbytes)
- fix ident

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

64 bit inode changes.

Add (commented out) IPSEC_NAT_T option.

branches: 1.7.2;
- Rename options NEW_BUFQ_STRATEGY -> options BUFQ_READPRIO.
(still commented out)
- Add (also commented out) options BUFQ_PRIOCSCAN.

Suggested by perry and soda on tech-kern.
Please refer options(4) for details for these options.

Remove attachment for the piixide(4) driver from all non-x86 kernel
configurations because Intel IDE disk controllers only exist as part
of Intel chipsets for x86 systems.

branches: 1.5.2;
Switch cobalt port to use MI pci_configure_bus(9)
with options PCI_NETBSD_CONFIGURE.
Patch from KIYOHARA Takashi on port-cobalt.

This change makes siop(4) (and maybe all other PCI devices
using pci mem space) work on cobalt.

branches: 1.4.2;
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.

branches: 1.1.2; 1.1.4;
New kernel configuration for use during Cobalt netboot or as a rescue kernel
image. The idea is to keep INSTALL as small as possible (XXXVERBOSE options are
off, no IP filtering, SCSI support etc.) to shoehorn into size limits imposed
by the Cobalt's firmware and to have full-blown GENERIC kernel which uses
NetBSD bootloader anyway.
