acpivmgenid(4): New driver for virtual machine generation ID.

Added to amd64/ALL and i386/ALL kernel configurations, and made
available as a loadable module acpivmgenid.kmod on x86, for now.
TBD: Add to all ACPI-supporting GENERIC kernels.

entropy(9): Factor out subroutines to reset and gather entropy.
`Reset' means we keep the data in the pool, but assume it had zero
entropy.  `Gather' means we request samples from all on-demand
sources and wait for the synchronous ones to complete.

No functional change intended, other than to expose new symbols --
just preparation to expose these to acpivmgenid(4), so it can use
these when the VM host notifies us that we, the guest, have been
cloned.

arc4random(3): Reseed if system entropy epoch changes.
This can happen, for example, if the system is a VM instance, and the
VM is cloned.

This incurs the cost of a system call on every arc4random call, which
is unfortunate, but
1. we don't currently have a (machine-independent) mechanism for
   exposing a read-only page to userland shared by the kernel to
   enable a cheaper access path to the entropy epoch; and
2. the algorithm here -- a simple application of ChaCha -- is likely
   also a bottleneck and could be much cheaper by
   (a) using sys/crypto/chacha for machine-dependent vectorized
       ChaCha code, and
   (b) filling a buffer (somewhere between a cipher block and a page)
       in a batch at a time, instead of running ChaCha to generate
       only 32 bytes at a time.
So although this might be a performance hit, the security benefit is
worthwhile and we have a clear path to do better than reversing the
performance hit later.

Applications need this in order to know when to reseed.  (We should
also expose it through a page shared read-only with userland for
cheaper access, but until we do, let's let applications get at it
through sysctl.)

arc4random(3): Add automatic tests.

This verifies that:
- arc4random zeroes its state and reseeds itself on fork
- arc4random reseeds itself on entropy consolidation (e.g., VM clone)
- arc4random falls back to global state if it can't allocate local
  state because address space limits cause mmap to fail

NOTE: This adds a new libc symbol __arc4random_global, but it's in
the reserved namespace and only used by t_arc4random, so no libc
minor bump.

viac7temp(4): rewrite temperature sensor to read value from MSR instead of using
documented cpuid instruction and eax register.

This approach is adapted from linux via-cputemp.c, no official documentation is
currently available. However, msr value seems to work on all tested CPUs while
documented cpuid instruction typically reports 0, even for my C7-D CPU.
msr value seems to have temperature in Celsius in lower 24-bits without fraction
(thus "msr & 0xffffff;" is used).

Tested on my personal systems based on CPUs below (i386 and amd64):
C7-D 1.6GHz (i386 only), Nano X2 L4350E, Nano X2 U4300, U2300 Nano, KX-U6580.
Also got one response via email which was based on Nano X2 L4050 (VE-900).

Nano reports independent values for each core.

KX-U6580 seems to show the same value for all cores but more testing is needed.

Since it works on amd64 capable CPUs, adding driver to GENERIC kernel config.

Also moving viac7temp man page to x86 instead of i386 (with updates).

In theory the change should add support for all VIA Nano CPUs and Zhaoxin CPUs
 at least up to KX-6000(G) series.

In the future I may need to introduce amd64 kernel module as well.

acpiec(4): Assert state is free when we start a transaction.
No functional change intended.

acpiec(4): Set sc_got_sci only when a transaction is over.

Before, when the acpiec thread noticed an SCI had been requested and
entered acpiec_gpe_state_machine to send the query command, it would
see the SCI is still requested -- because it had yet to acknowledge
it by setting the query command! -- and think the EC was asking for a
_second_ SCI.

So once the first SCI transaction was over, it would start a second
one, even though the EC hadn't asked for another -- and this would
wedge on some ECs.

Now, acpiec_gpe_state_machine waits to see what state we transition
to before taking the SCI bit to mean we need to notify the acpiec
thread to handle another query.

That way, when the acpiec thread enters acpiec_gpe_state_machine with
EC_STATE_QUERY, it can send the query command first, with the side
effect of clearing the SCI bit in subsequent reads of the status
register, and it won't think another SCI has been requested until it
returns to EC_STATE_FREE and sees the SCI bit set again in the status
register.

i386: Re-enable HEARTBEAT.

revert previous change to enable HEARTBEAT.

the new code has a "needs 64-bit atomic ops" trigger:

but time_uptime is a 64-bit value, and this trips CTASSERT().

Add missing virtio devices to x86 ALL kernels

Driver for DaynaPORT SCSI/Link (dse.4).

Written by Hiroshi Noguchi, of which an updated version was posted to
port-mac68k in 2001.

Attachments were added to kernel configs for platforms that already had
the Cabletron (se.4) driver added, although other platorms may benefit.

Reviewed on tech-net by Izumi Tsutsui.

x86: Support EFI runtime services.

This creates a special pmap, efi_runtime_pmap, which avoids setting
PTE_U but allows mappings to lie in what would normally be user VM --
this way we don't fall afoul of SMAP/SMEP when executing EFI runtime
services from CPL 0.  SVS does not apply to the EFI runtime pmap.

The mechanism is intended to work with either physical addressing or
virtual addressing; currently the bootloader does physical addressing
but in principle it could be modified to do virtual addressing
instead, if it allocated virtual pages, assigned them in the memory
map, and issued RT->SetVirtualAddressMap.

Not sure pmap_activate_sync and pmap_deactivate_sync are correct,
need more review from an x86 wizard.

If this causes fallout, it can be disabled temporarily without
reverting anything by just making efi_runtime_init return immediately
without doing anything, or by removing options EFI_RUNTIME.

amd64-only for now pending type fixes and testing on i386.

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.

Add MFI_DEBUG and MFII_DEBUG.

Disable amdgpu as it uses floating point arithmetics and subr_kcov
doesnt handle it.

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.

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

reviewed by msaitoh@n.o and knakahara@n.o

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

Introduce per-cpu IDTs

This is realized by following modifications:
- Add IDT pages and its allocation maps for each cpu in "struct cpu_info"
- Load per-cpu IDTs at cpu_init_idt(struct cpu_info*)
- Copy the IDT entries for cpu0 to other CPUs at attach
   - These are, for example, exceptions, db, system calls, etc.

And, added a kernel option named PCPU_IDT to enable the feature.

Remove uyap, USB YAP phone firmware loader.

And the associated ezload EZ-USB code, which is only used by uyap.

a lot since 2001 when uyap(4) was added to the tree.

Pointed out by maxv, thanks.

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.

Sync with head.

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 filemon(4).

Discussed on tech-kern:
https://mail-index.NetBSD.org/tech-kern/2020/01/13/msg025938.html

This was never (intentionally) enabled by default, and the design has
some shortcomings.  You can get mostly the same results with ktrace,
as in usr.bin/make/filemon/filemon_ktrace.c which is now used instead
of filemon for make's meta mode.

If applications require higher performance than ktrace, or nesting
that ktrace doesn't support, we might consider adding something back
into the vfs system calls themselves, without hijacking the syscall
table.  (Might want a more reliable output format too, e.g. one that
can handle newlines in file names.)

Remove Token Ring 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.

Sync with head.

Remove uyurex(4).

This is a driver for a "nonsense machine" made by the art group Maywa-Denki
in 2008. It was disabled by default.

Unfortunately even so it draws development attention (flaws found in the
code, MP-ification needs) and it is best not to continue to maintain this
driver.

Proposed without objections on tech-kern.

Revert the removal of filemon.

Remove ISDN from the kernel. It has remained unmaintained for a long time,

Remove undocumented hack.

Switch to the temporary stack right away when booted via multiboot. GRUB
happens to give a correct stack, but it is not guaranteed by the spec. This
temporary stack will be reset later, which is fine.
Fixes PR/50245.

Pfff, use %ss and not %ds. The latter is controlled by userland, the former
contains the kernel value (flat); FreeBSD fixed this too a few weeks ago.
As I said earlier, this dtrace code is complete bullshit.

Don't allow userland to create 286/386 call gates anymore - they are not
used by Wine. While here, don't allow it to overwrite the static entries
either, don't allow unknown entry types, remove LDT_DEBUG, and style.

Add ALPS pms support

Remove support for vm86 on i386. It is bug-friendly, and there is no point
in having kernel support for this: the instruction set of the CPU is small,
and it can easily be emulated in userland entirely. There are also several
assumptions in the code that are not respected, and the slightest confusion
in the trap frame can lead to ring0 exploits.

vm86 has received zero maintenance. As far as I can tell, it was added
20 years ago in order to make doscmd work. But doscmd has not been
maintained either, and was removed from pkgsrc in 2011. dosbox can be used
instead: it does not require kernel support, and will produce better
results than our flimsy implementation.

Pass 1. (many pieces still in the tree)

Remove compat_ibcs2 from i386. After a discussion on port-vax, it turns
out that compat_ibcs2 does not implement the iBCS2 standard - which is
x86-specific - but rather SVR3. Our real iBCS2 implementation was a
mixture of compat_ibcs2 and compat_svr4, and was only partial. Keeping
support for this in i386 is totally irrelevant today. I also asked on
port-i386 but didn't wait long.

The main issue is that compat_ibcs2 should have been called compat_svr3.
But CVS does not support renaming files, and moving things around is both
painful and tiring, even more so when no one seems to be interested in
doing this work or in the feature at all. For now compat_ibcs2 is available
on Vax and will stay, until someone (not me) cleans it up.

Remove TCP_COMPAT_42 from the config files. Pass 3.

Remove svr4 from the config files.

Remove DEBUG_HPUX (does not exist).

Remove IBCS2_DEBUG (does not exist).

Add wsbell

Add options CAN and pseudo-device canloop to ALL kernel configs.
Add the same commented out to i386/amd64 GENERIC and OLIMEXLIME2 (A20-based).
Also add commented out awincan0 in OLIMEXLIME2.

rename u3ginit driver to umodeswitch

gson@ informs me the Alea I and II have the same USB product id.

Thus, ualea(4) should work for both of them.  Rename USB product id
ARANEUS ALEA_II to ARANEUS ALEA to reflect this.

No functional change intended, except perhaps via usbdevs.

New rndsource driver for Araneus Alea II TRNG USB devices.

Disabled by default in x86/GENERIC and usbdevices.config pending
review and testing without rump ugenhc in the way, but enabled in
x86/ALL for compile-testing.

(Hi gson!  Finally found a round tuit in my pocket, next to a certain
rectangular one.)

Merge netbsd-7-nhusb:
- API / infrastructure changes to support memory management changes.
- Memory management improvements and bug fixes.
- HCDs should now be MP safe
- conversion to KERNHIST based debug
- FS/LS isoc support on ehci(4).
- conversion to kmem(9)
- Some USB 3 support - mostly from Takahiro HAYASHI (t-hash).
- interrupt transfers now get proper DMA operations
- general bug fixes
     - kern/48308
     - uhub status notification improvements
     - umass(4) probe fix (applied to HEAD already)
     - ohci(4) short transfer fix
- Change the SOFTINT level from NET to SERIAL for the USB softint handler.
  This gives the callback a chance of running when another softint handler
  at SOFTINT_NET has blocked holding a lock, e.g. softnet_lock and most of
  the network stack.

Sync with HEAD

A few changes:
 * Use markers to reduce false sharing.
 * Remove XENDEBUG_SYNC and several debug messages, they are just useless.
 * Remove xen_vcpu_*. They are unused and not optimized: if we really
   wanted to flush ranges we should pack the VAs in a mmuext_op array
   instead of performing several hypercalls in a loop.
 * Start removing PG_k.
 * KNF, reorder, simplify and remove stupid comments.

Add DKWEDGE_METHOD_RDB option, which is enabled for x86, commented out for
other platforms by default.

PR kern/51208
Add DISKLABEL_EI option (and also FFS_EI if missing), commented out except for
ALL on amd64 and i386.

There is currently an ugly mix between the PERFCTRS subsystem (MI), and
i386's own PMC interface (MD). Stop using PERFCTRS and use PMC instead.
While here remove some unused flags, which are wrong on the latest CPUs
anyway.

To my knowledge this feature is no longer supported at the moment. The
manual page for wsdisplay(4) should probably also be updated to reflect
this situation.

Disable PAX_SEGVGUARD.

We actually have a big problem: the fileassocs are never deleted.
Therefore, if a user generates a lot of buggy binaries and launches them
all, the kernel will allocate memory again again and again for all these
entries and will never free them (unless the files are deleted from the
disk). Which means that a user can too easily put the kernel under memory
pressure.

Remove KMEMSTATS. Normally it's ok now.

Config around agp(4) is done in quite wrong direction.

Disable BSDLABEL and MBR DKWEDGE methods again since sysinst does not work

Add options COMPAT_44, which controls mostly MD code but should be in

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.

Rebase to HEAD as of a few days ago.

- Enable Wedge support for MBR/BSDLABEL where it was commented out.
- Add apple partition support where it was missing
- Add comments where missing

Add "options COMPAT_70" to all kernel configuration files that

Remove dead code. The kernel already checks for PT_INTERP sections, and puts

trying to find this section again. Just use "itp".

DEBUG_FREEBSD_ELF is now unused, so remove its references in amd64/conf/ALL

Add a driver for Realtek RTS5209/RTS5229 Card Reader.
Ported from OpenBSD.

Add umcs(4)

Remove support for 'external' floating point units and the MS-DOS
  compatible method of handling floating point exceptions.
Make kernel support for teh fpu non-optional (486SX should still work).
Only 386 cpus support external fpu, and i386 support was removed years ago.
This means that the npx code no longer uses port 0xf0 or interupt 13.
All the "npx at isa" lines go from the configs, arch/i386/isa/npx.c
  is now mandatory for all i386 kernels.
I've renamed npxinit() to fpuinit() and npxinit_cpu() to fpuinit_cpu()
  to match the very similar amd64 functions.
The fpu of the boot cpu is now initialised by a direct call from
  cpu_configure(), this enables FP emulation for a 486SX.
  (for amd64 the cr0 values are set in locore.S and similar).
This fixes a long-standing bug in linux_setregs() - which did not
  save the fpu regsiters if they were active.
I've test booted a single cpu i386 kernel (using anita).
amd64 builds - none of teh changes should affect it.
The i386 XEN kernels build, but I'm not sure where they set cr0, and
  it might have got lost!

Add RAID_DIAGNOSTIC so that code gets built.

Comment out npf for now, as we can't have both NPF and PF in the

Apply almost all fixes and improvements from netbsd-6 except for
the rev. 1.196's iqdrops' change.

- Add the detach code.
- Add code for WOL, ASF, IPMI and Intel AMT. WOL is disabled by default
- Add Yet another workaround for ICH8.
- 82576 is dual port, so check the FUNCID and increment the MAC address for
  the 2nd port.
- Fix the names of 82577L[MC] LAN controllers (for mobile).
- Fix CTRL_EXT_SWDPIN() and CTRL_EXT_SWDPIO() macros. The bit order of the
  SW definable pin is not 6543 but 3654!!!
- Rewrite the code to read MAC address from eeprom.
- Add 82580 support.
- 82571 quirk. Only 82571 shares port 0 of EEMNGCTL_CFGDONE.
- The document says that the TDH register must be set after
  TCL.EN is set on 82575 and newer devices.
- Fix some register names. No functional change.
- Omit U+00AE "REGISTERED SIGN" in a product name due to its non-ASCII nature.
- Stop wm(4) from needlessly resetting when you add or delete a vlan(4).
- Fix MAC address check on 8257[156] and 80003 case. Some cards have non 0xffff
  pointer but those don't use alternative MAC address in reality. So we check
  whether the broadcast bit is set or not like Intel's e1000 driver.
  Fixes PR kern/44072 reported by Jean-Yves Moulin.
- Add PCH2(and 82579) support. Fixes PR#46487
- Add yet another 82567V support.

- Fix a bug that PHY isn't set to low-power mode on PCH and PCH2.
- Add WM_DEBUG_NVM. If WM_DEBUG_NVM is enabled, dump the FLASH ROM data.
- Skip 64bit BAR correctly.
- Fix RAL_TABSIZE for ICH8, 82576, 82580 and I350.
- Use 82580(and I350) specific PHY read/write functions. Fixes PR#47542.
- Style fix. Fix typo in comment. Fix comments. Add comments.

Mention wsconscfg(8) needs WSDISPLAY_COMPAT_USL
If a port is going to have wscons for virtual terminals then it really make=
s
sense to enable WSDISPLAY_COMPAT_USL so the system can switch between the
virtual terminals...
Adjust the WSDISPLAY_COMPAT_USL comment to mention wsconscfg, to at least
give a hint that its not just for third party compat. No functional change.

add uipad

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

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.

remove Xbox support

Import of the virtio driver written by MINOURA Makoto <minoura@netbsd.org>
with minor changes to make it compile an run on -current.  This driver
speeds up disk and network access in virtual environments like KVM.

Enabled on i386 and amd64.  Tested with a CentOS 5.7 x86_64 host.

See http://ozlabs.org/~rusty/virtio-spec/virtio.pdf for the specification.

add vmt(4)

Add the plumbing so one could compile filemon(4) into a kernel.

Install dev/i2c/i2c_io.h and implement the API in the iic(4) driver.
Obsolete the I2C_SCAN option as this can now be done from userland.

options PMS_DISABLE_POWERHOOK is obsolete.

Borrow ``xs_watch'' thread context?
- bug hunting in xbd + xennet resume. Rings are currently thrashed upon
resume, so current implementation force flush them on suspend. It's not
really needed.

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.

Import NPF - a packet filter.  Some features:

- Designed to be fully MP-safe and highly efficient.

- Tables/IP sets (hash or red-black tree) for high performance lookups.

- Stateful filtering and Network Address Port Translation (NAPT).
  Framework for application level gateways (ALGs).

- Packet inspection engine called n-code processor - inspired by BPF -
  supporting generic RISC-like and specific CISC-like instructions for
  common patterns (e.g. IPv4 address matching).  See npf_ncode(9) manual.

- Convenient userland utility npfctl(8) with npf.conf(8).

NOTE: This is not yet a fully capable alternative to PF or IPFilter.
Further work (support for binat/rdr, return-rst/return-icmp, common ALGs,
state saving/restoring, logging, etc) is in progress.
