Add gscan(4), a driver for USB to CAN bus adapters.
This driver supports the Geschwister Schneider USB to CAN adapter, and
clones supported by the open-source candleLight firmware.

Add gscan to evbarm GENERIC (which already supports CAN family and the
sunxican(4) driver by default), and to amd64 ALL.

No functional change intended.

Leave `# XXX ?' comments where I don't know why the driver in
question is excluded. (Typical reason is that PAGE_SIZE is not 4096
but I didn't investigate -- if you do investigate, please either
update the comment if you determine a reason, or enable the driver if
you don't.)

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.

Plan to pullup to at least netbsd-10.

Patch mainly reviewed by riastradh.

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.

This exists for compatibility with a Linux interface which was apparently
deprecated in Linux 2.6. There are various mailing list threads going

the conclusion is that scanner software has all moved to using ugen(4)
instead, and enabling this driver will not help you scan things.

 1.146  09-Feb-2020  jmcneill Retire azalia(4).
 1.145  08-Feb-2020  maxv Retire KLEAK.

KLEAK was a nice feature and served its purpose; it allowed us to detect
dozens of info leaks on the kernel->userland boundary, and thanks to it we
tackled a good part of the infoleak problem 1.5 years ago.

Nowadays however, we have kMSan, which can detect uninitialized memory in
the kernel. kMSan supersedes KLEAK: it can detect what KLEAK was able to
detect, but in addition, (1) it operates in all of the kernel and not just
the kernel->userland boundary, (2) it requires no user interaction, and (3)
it is deterministic and not statistical.

That makes kMSan the feature of choice to detect info leaks nowadays;
people interested in detecting info leaks should boot a kMSan kernel and
just wait for the magic to happen.

KLEAK was a good ride, and a fun project, but now is time for it to go.

Discussed with several people, including Thomas Barabosch.
 1.144  03-Feb-2020  maya Remove more urio(4) traces.

Pointed out by maxv, thanks.
 1.143  29-Jan-2020  maya 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.
 1.142  25-Jan-2020  thorpej 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.
 1.141  20-Jan-2020  thorpej Remove FDDI support.
 1.140  19-Jan-2020  riastradh 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.)
 1.139  19-Jan-2020  thorpej Remove Token Ring support.
 1.138  19-Jan-2020  thorpej 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.
 1.137  19-Jan-2020  thorpej Remove the strip(4) - Starmode Radio IP - pseudo-device driver. It is
long since obsolete.
 1.136  17-Jan-2020  maya 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.

work well on systems where more than one I2C bus is present.

N.B. The x86 platforms are sort of a mess, here... legacy indirect
config and ACPI direct config sort of smashed together with the
same config file directives.

XXX i386 ALL kernel build is failing
 1.85  08-Apr-2018  mrg turn on GCC spectre v2 mitigation options.

XXX: amd64 ALL doesn't build for me right now
 1.84  29-Mar-2018  maxv Remove TCPREASS_DEBUG. It was introduced 20 years ago when the reassembler
was being developed, but it's irrelevant today. Makes the code clearer.
 1.83  16-Mar-2018  maxv Remove ipkdb from i386. Also remove unused references in amd64.

I already talked about doing that six months ago on port-i386@. Back then
it was as general cleanup, but now, with SVS etc, we do actually have
good reasons for simplifying the entry points.

Ok kamil@. (christos@ was in the conversation too)
 1.82  25-Feb-2018  pgoyette branches: 1.82.2;
As requested by chuq@, add the new imc devices to the i386 and amd64
ALL kernels.
 1.81  12-Feb-2018  joerg Add a new option CISS_NO_INTERRUPT_HACK for driving ciss(4) by callouts.
This is intended as workaround for certain Xen issues with dom0 kernels
and will likely want to have a high HZ value as well for decent
performance.
 1.80  27-Jan-2018  pgoyette Update amdzentemp(4) attachment info. Also for ALL, remove duplicate
entry for amdtemp(4).
 1.79  25-Jan-2018  christos add amdzentemp
 1.78  13-Jan-2018  christos added commented out AUTOFS pseudo-device entries
 1.77  10-Jan-2018  knakahara add ipsec(4) interface to amd64/GENERIC and amd64/ALL configs.

XXX: Does not work yet
 1.75  10-Dec-2017  bouyer Add dwiic, ihidev and ims
 1.74  02-Dec-2017  maxv Drop COMPAT_10 on amd64. The support for it comes down to one ifdef in
trap.c - code that is incorrect anyway, there were originally three lcall
LDT slots, and here only one instruction is decoded.

Given that one of these slots was used by BSDi's syscall, also remove the
references to COMPAT_NOMID to make clear we don't support that (it already
is not enabled).

Note: for some reason, COMPAT_10 does not even compile, because there are
"multiple definitions of _KERNEL_OPT_COMPAT_...", and I don't really
understand where this comes from.
 1.73  02-Dec-2017  maxv Remove options that do not exist on amd64.
 1.72  25-Nov-2017  jmcneill Add qemufwcfg (QEMU Firmware Configuration device)
 1.71  14-Sep-2017  mrg 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.
 1.70  13-Sep-2017  sevan Remove support for VERIFIED_EXEC_FP_RMD160, VERIFIED_EXEC_FP_SHA1, and VERIFIED_EXEC_FP_MD5 options.
These algorithms are either broken or on their way to being broken.

ok riastradh
 1.69  03-Sep-2017  maxv Remove useless debug code, and split trap() into smaller functions, easier
to understand. NMIs take another, faster path now. No functional change
beyond that.
 1.68  30-Aug-2017  maxv 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.
 1.67  13-Aug-2017  christos Add ALPS pms support
 1.66  12-Aug-2017  maxv 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)
 1.65  09-Aug-2017  maxv Remove references to compat_ibcs2.
 1.64  29-Jul-2017  maxv Remove DEBUG_HPUX (does not exist).
 1.63  29-Jul-2017  maxv Remove IBCS2_DEBUG (does not exist).
 1.62  28-Jul-2017  maxv Remove TCP_COMPAT_42 from the config files. Pass 1.
 1.61  28-Jul-2017  riastradh Add some more bogus compat options to amd64/ALL for compile-testing.
 1.60  14-Jun-2017  pgoyette Add wsbell
 1.59  27-May-2017  bouyer branches: 1.59.2;
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.

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.
 1.55  17-Apr-2017  riastradh 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.)
 1.54  08-Mar-2017  maxv 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.
 1.53  26-Feb-2017  rin Add DKWEDGE_METHOD_RDB option, which is enabled for x86, commented out for
other platforms by default.
 1.52  19-Feb-2017  rin PR kern/51208
Add DISKLABEL_EI option (and also FFS_EI if missing), commented out except for
ALL on amd64 and i386.
 1.51  18-Feb-2017  maxv PERFCTRS -> PMC (not implemented anyway)
 1.50  16-Feb-2017  knakahara add l2tp(4) to amd64/GENERIC and amd64/ALL config.
 1.49  12-Jan-2017  ryo branches: 1.49.2;
white space police
 1.48  27-Dec-2016  pgoyette Add BIOHIST (and belatedly, UVMHIST) to the ALL kernels for i386 and amd64.

XXX Perhaps it should be added to others as well? Perhaps just as comments?
 1.47  23-Dec-2016  maya add SCTP_DEBUG to ALL kernels
 1.46  18-Dec-2016  dholland Whitespace.

device.

 1.34  01-May-2016  nonaka Added nvme(4) for Non-Volatile Memory Host Controller Interface devices.
Ported from OpenBSD.
 1.33  10-Nov-2015  tnn Add "pseudo-device iscsi" to ALL and as a commented out hint in XEN3_*
 1.32  25-Oct-2015  khorben Remove references to SPLASHSCREEN_PROGRESS

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.
 1.31  26-Sep-2015  maxv 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.
 1.30  08-Aug-2015  maxv Remove KMEMSTATS.
 1.29  03-May-2015  pgoyette Update to include the tco driver (it was previously included as part of
ichlpcib).
 1.28  28-Apr-2015  rjs Add DCCP.
 1.27  06-Mar-2015  riastradh Fix tabbing of drm lines.
 1.26  06-Mar-2015  riastradh Fix commented nouveau in amd64/GENERIC. Add nouveau to amd64/ALL.

Remove NV_DEBUG from amd64/ALL -- it breaks nouveau, and I can't find
any use of it in src/sys outside arch/atari/dev/nvram.c, which surely
has no relevance to amd64.

(Nouveau has an internal NV_DEBUG(...) macro for debug messages.)
 1.25  13-Feb-2015  nonaka iwm(4) works now, but 2.4GHz only.

Remove unused extended attributes kernel options

As Masao Uebayashi pointed to me, UFS_EXTATTR_AUTOSTART, LFS_EXTATTR_AUTOSTART
and UFS_EXTATTR_AUTOCREATE are not used anywhere in the code. Remove them
as they have been obsolete for a long time:
UFS_EXTATTR_AUTOSTART was replaced by mount -o extattr
LFS_EXTATTR_AUTOSTART was created to match obsolete UFS_EXTATTR_AUTOSTART
UFS_EXTATTR_AUTOCREATE was replaced by sysctl vfs.ffs.extattr_autocreate

XXX
Config around agp(4) is done in quite wrong direction.
"pchb <- (agpbus) <- agp <- agp_*"
should be:
"pchb <- (pcibus) <- agp_* <- (agpbus) <- agp"
 1.20  19-Sep-2014  christos Add HDAUDIOVERBOSE
 1.19  19-Sep-2014  christos Disable BSDLABEL and MBR DKWEDGE methods again since sysinst does not work
with wedges.
 1.18  24-Aug-2014  jnemeth Create an "options MODULAR_DEFAULT_AUTOLOAD" config option and add
it to all kernel configs that contain "options MODULAR". This
option turns on module autoloading by default (which is the current
default). This allows people who don't want module autoloading on
by default to disable it by simply removing/commentting this line.
 1.17  23-Aug-2014  dholland Add options COMPAT_44, which controls mostly MD code but should be in
here anyway.
 1.16  23-Aug-2014  dholland 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.
 1.15  18-Aug-2014  christos branches: 1.15.2;

 1.10  24-Jun-2014  maxv Remove dead code. The kernel already checks for PT_INTERP sections, and puts
their content into "itp". There's no need for re-reading the whole binary and
trying to find this section again. Just use "itp".

DEBUG_FREEBSD_ELF is now unused, so remove its references in amd64/conf/ALL
and i386/conf/ALL.
 1.9  10-Jun-2014  hikaru Add VMware VMXNET3 ethernet driver from OpenBSD, vmx(4).

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.
- kern/49065 - ifconfig tun0 ... sequence locks up system / lockup:
softnet_lock held across usb xfr
- kern/50491 - unkillable wait in usbd_transfer while using usmsc0
on raspberry pi 2
- kern/51395 - USB Ethernet makes xhci hang
- Various improvements to slhci(4)
- Various improvements to dwc2(4)

Create an "options MODULAR_DEFAULT_AUTOLOAD" config option and add
it to all kernel configs that contain "options MODULAR". This
option turns on module autoloading by default (which is the current
default). This allows people who don't want module autoloading on
by default to disable it by simply removing/commentting this line.

Remove unused extended attributes kernel options

As Masao Uebayashi pointed to me, UFS_EXTATTR_AUTOSTART, LFS_EXTATTR_AUTOSTART
and UFS_EXTATTR_AUTOCREATE are not used anywhere in the code. Remove them
as they have been obsolete for a long time:
UFS_EXTATTR_AUTOSTART was replaced by mount -o extattr
LFS_EXTATTR_AUTOSTART was created to match obsolete UFS_EXTATTR_AUTOSTART
UFS_EXTATTR_AUTOCREATE was replaced by sysctl vfs.ffs.extattr_autocreate

Add some definitions from OpenBSD, needed by the upcoming mfii driver.
No functionnal change.

-

Move registers definitions to a separate file, needed for the upcomning mpii
driver. No functionnal change.

-

Add mpii(4), a driver for LSI Megaraid Fusion controllers.
Ported from OpenBSD. This driver is MP-safe.

Note that the earlier fusion controllers (Megaraid 2208, codenamed Thunderbold)
are also supported by mfi(4). mpii will take precedence if both drivers
are enabled.

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.

PR kern/58632: getentropy(2) and arc4random(3) do not reseed on VM

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

through sysctl.)

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

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): Clarify lock order and sprinkle lock assertions.

acpiec(4): Sprinkle comments.

No functional change intended.

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.

Better to keep the device_t isolated to public interfaces. Simpler
internally this way.
No functional change intended.

acpiec(4): Factor out if (state == FREE) cv_signal(sc_cv).

In principle this could have a functional change, but at worst, it is
to signal more wakeups than needed, which should always be safe.
acpiec(4): Take a lock around acpiec_cold updates.

Otherwise we race with readers -- probably harmlessly, but let's
avoid the appearance of problems.
XXX Maybe acpiec_suspend and acpiec_shutdown should interrupt
transactions and force them to fail promptly?
XXX This looks bad because acpiec_cold is global and sc->sc_mtx
doesn't look like it's global, but we expect to have only one
acpiec(4) device anyway from what I understand. Maybe we should move
acpiec_cold into the softc?
