gpioirq(4) version 2

This update makes this driver more than just an example and allows for:

o More than one pin to be attached to a gpioirq instance. That is,
the mask parameter can be greater than 0x01 now.

o A /dev/gpioirqN device that allows GPIO pin interrupts to be
transported into userland. This is a device that can be opened for
reading with a simple fixed output indicating the device unit, pin
number and current pin state.


This update was used as part of a physical intrusion detection system
where multiple switches (i.e. window magnetic reed switches and etc.)
are tied to a bunch of GPIO inputs with userland software that reacts
to the pins changing state.

MAKEDEV: make nvmm node group-writable (was readable only; group nvmm)

viocon(4): New virtio tty driver imported from OpenBSD.

viocon* at virtio?

/dev/ttyVI??

Tested under qemu with:

qemu-system-aarch64 ... \
-device virtio-serial \
-chardev socket,path=/tmp/ttyVI00,server=on,wait=off,id=ttyVI00 \
-device virtconsole,chardev=ttyVI00,name=org.NetBSD.dev.ttyVI00 \
...

I updated MAKEDEV.conf to create /dev/ttyVI?? on all ports where it
looks likely to work based on:
(a) having pci or a non-pci virtio attachment,
(b) `qemu-system-$ARCH -M ?' mentioned something resembling the port,
and
(c) `qemu-system-$ARCH -device virtio-serial' launched without
complaining about the virtio-serial device.

(Criterion (c) excluded sparc and sparc64.)

MAKEDEV.tmpl: make /dev/wsfont world-readable

on wsfont(4) device opened for writing and relied on its restrictive
root-only permissions to restrict who can load fonts.

A driver and user land utility for the Sparkfun Serial Controlled Motor
Driver module as illustrated here:

https://www.sparkfun.com/products/13911

A SCMD module is a ARM SOC simular to a Arduino in front of a motor
driver chip. The single SCMD module can control two motors and up to
16 additional modules can be chained together using an internal I2C
bus. One can interface with the SCMD using tty uart commands, SPI or
I2C. The driver in this commit adds a kernel driver for the I2C and
SPI interfaces. The command line utility provides a set of
convenience commands that support most of the functions of the SCMD
and is able to use the tty uart mode, SPI user land or the included
kernel driver in a uniform manor.

The use of the SCMD module is mostly for small robots and the like,
but it can control anything that is controllable by voltage.

Driver for the Sensirion SHT30/SHT31/SHT35 temperature and humidity
sensor such as:

https://www.adafruit.com/product/2857

This is a higher priced sensor with a lot of features, including the
ability to do sub-second periodic updates. The driver supports
everything about the sensor except for the alert pin.

PR/56452: RVP: MAKEDEV should also create /dev/dri/renderD* devices

efi: Add /dev/efi character device

Introduce a /dev/efi character device that provides a means for accessing
UEFI RT variable services from userland. Compatible with the FreeBSD ioctl
interface for ease of porting their libefivar and associated tools.

The ioctl interface is defined in sys/efiio.h.

To enable support for this on an arch, the kernel needs `pseudo-device efi`
and the MD EFI implementation needs to register its backend by calling
efi_ops_register(). This commit includes an implementation for Arm.

smbios: Add character device for accessing SMBIOS tables

The /dev/smbios character device gives an aperture into physical memory
that allows read-only access to the SMBIOS header and tables.

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.

acpi: add character device for accessing ACPI tables

The /dev/acpi character device gives an aperture into physical memory
that allows only read access to known ACPI tables: RSDP, XSDT/RSDT, and
the root tables. Adapt acpidump(8) to use this interface by default,
falling back to the old /dev/mem method if it is not available or if
ACPIDUMP_USE_DEVMEM=1 is set in the environment. The user visible benefit
of this change is that "options INSECURE" is no longer required to
dump ACPI tables.

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.

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.)

Revert the removal of filemon.

Retire filemon, discussed on tech-kern@.

MAKEDEV: add entry for vio9p(4)

Add the "nvmm" group, and make nvmm_init() public. Sent to tech-kern@ a few

XXX pullup-9

Replace major number in MAKEDEV for vhci

Add vHCI, a driver which allows to send and receive USB packets directly
from userland via /dev/vhci. Using this, it becomes possible to test and
fuzz the USB stack and all the USB drivers without having the associated
hardware.

The vHCI device has four ports independently addressable.

For each xfer on each port, we create two packets: a setup packet (which
indicates mostly the type of request) and a data packet (which contains
the raw data). These packets are processed by read and write operations
on /dev/vhci: userland poll-reads it to fetch usb_device_request_t
structures, and dispatches the requests depending on bRequest and
bmRequestType.

A few ioctls are available:

VHCI_IOC_GET_INFO - Get the current status
VHCI_IOC_SET_PORT - Choose a vHCI port
VHCI_IOC_USB_ATTACH - Attach a USB device on the current port
VHCI_IOC_USB_DETACH - Detach the USB device on the current port

vHCI has already allowed me to automatically find several bugs in the USB
stack and its drivers.

MAKEDEV.tmpl: Create nodes for 16 USB hubs

As proposed on current-users, but with better formatting.

Raise the number of uhid nodes from 4 to 16.

My keyboard and mouse use multiple device nodes each. I can't use
any other devices once they're attached. With my keyboard, mouse,
and two game controllers attached, a total of 9 nodes are required.

Particularly, high-end keyboards with N-key rollover support require
more device nodes, since they pretend to be multiple keyboards to work
around limitations in the uhid compat spec.

My original intention was to raise it from 4 to 12, but martin
suggested increasing it to 16.

"somewhat insane, but so is reality" - mlelstv

Add experimental userland interface to IPMI driver. Currently, transactions
(like sensor readout) are locked, so that a userland program may interfere with
envsys operation.

To use this you need a program like ipmitool built with OpenIPMI support.

Double the number of wedge device nodes

Actually use unit number for iscsi device.

Add srt(4) to /etc/MAKEDEV and corresponding update to MAKEDEV.8 man page.

Add userland driver to spi framework.

Previously spi would configure the controller to use the lowest speed of
all connected devices since the kernel started and to fail attempted mode
changes. This is now improved to keep individual modes and speeds for each
slave and to reconfigure the controller as necessary for each transfer.

Added man page for spi(9).

Add KCOV - kernel code coverage tracing device

The KCOV driver implements collection of code coverage inside the kernel.
It can be enabled on a per process basis from userland, allowing the kernel
program counter to be collected during syscalls triggered by the same
process.

The device is oriented towards kernel fuzzers, in particular syzkaller.

Currently the only supported coverage type is -fsanitize-coverage=trace-pc.

The KCOV driver was initially developed in Linux. A driver based on the
same concept was then implemented in FreeBSD and OpenBSD.

Documentation is borrowed from OpenBSD and ATF tests from FreeBSD.

This patch has been prepared by Siddharth Muralee, improved by <maxv>
and polished by myself before importing into the mainline tree.

All ATF tests pass.

Remove the satlink driver. It was disabled everywhere, had no man page and
no use either. Spotted by thorpej in PR/21345, ok christos.

Add NVMM - for NetBSD Virtual Machine Monitor -, a kernel driver that

We install

/usr/include/dev/nvmm/nvmm.h
/usr/include/dev/nvmm/nvmm_ioctl.h
/usr/include/dev/nvmm/{arch}/nvmm_{arch}.h

And the kernel module. For now, the only architecture where we do that
is amd64 (arch=x86).

NVMM is not enabled by default in amd64-GENERIC, but is instead easily
modloadable.

As (briefly) discussed on current-users, change the way that MAKEDEV checks

to pick one if not) to be more shell friendly.

Note that while the method here is the same as was discussed on the list,
the actual implementation is free of the typos, and just pure lunacy that
was in the code that was shown there.

Also note these changes are intended to be completely internal, there
should be no visible impact upon the way that MAKEDEV works.

When MAKEDEV creates a memory file system, let it try mount_tmpfs(8)

of inodes more accurately.

Discussed in tech-userlevel.

In MAKEDEV.tmpl:
* Add a nooutput function to be used instead of redirecting to /dev/null,
because /dev/null might not exist early in the boot sequence. This
should fix a bug in which the pax autodetection failed when used from
init(8) with a read-only root file system without a /dev/null.
* Move most of the main program into a new makedev_main function,
to allow reuse by MAKEDEV.local.

In MAKEDEV.local:
* Use the new makedev_main function defined in MAKEDEV. This allows
MAKEDEV.local to support all the options understood by MAKEDEV, instead
of only a subset. This should fix a bug in which the setup() function
could try to use pax mode even though that was previously not supported.

In MAKEDEV.local man page:
* Update list of command line options.
* Don't explain all the options, just refer to MAKEDEV(8) man page.
* Remove BUGS section now that all MAKEDEV options are supported
by MAKEDEV.local.

* Move duplicated code into a check_pax function, and improve the test
for whether pax is likely to be usable.
* Don't try to create an mfs with fewer than 10 inodes.
* Add a missing exit in an error case.

Pass "-pe" flag to pax, otherwise the devices get created with
permissions modified by the umask.

* MAKEDEV's "-M -M" option was always intended for use only by init(8).
Improve the documentation around that.
* The "-p pax", "-m mknod", and "-s" (mtree specfile) options should
always have been mutually exclusive. Now enforce that.
* The "-f" option didn't ever work with pax or mtree mode; document that,
and make it an error to try something that won't work.
* Make pax mode the default, if no other options prevent this, and if
"pax -w -M" appears to be usable.
* Add missing options to a usage message.

increases of up to 20 times have been observed, but 3 to 5 times is
more common).
* One "-M" flag will create the mfs file system but not redirect output

If we are called as 'sh MAKEDEV ...', then we would previously have

ramdisk images.

Provide a new MAKEDEV.subr file containing utility functions for

Rework the sequence that ptys get allocated so that we don't end up with
gaps in the sequence of minor numbers as we allocate ptys. Having gaps
has 2 bad side effects:
- ptm does not like it
- we allocate a lot of storage that we'll never use in the pty array
(the current scheme allocated 62 ptys 0-15,256-301, so we needed
302 entries to get 64).
Now we allocate ptys in groups of 16 or 14 instead of 64, and we follow
the minor number order.
We default to 64 pty's by building pty0-3, which is all using the old
traditional pty names. Of course to do this, the shell code is a bit
convoluted.

don't depend on printf.

Rework MAKEDEV:

* Use "mknod -F netbsd -r" to create nodes, instead of
"rm ; mknod; chmod; chown".
This means permissions & ownership of existing nodes will
not be changed.
This is up to 30% faster when populating an empty /dev,
and nearly 2x faster when re-running on an existing /dev.

* New options:
-f force change of permission & ownership of existing
devices
-m mknod override name/path of mknod program
(which defaults to $TOOL_MKNOD, then "mknod").
-s generate mtree(8) specfile instead of creating devices

* Remove /usr/etc from $PATH; not needed anymore.

* Provide functions to create devices & directories:
mkdev name [b|c] major minor [mode{=600} [gid{=0} [uid{=0}]]]
create device node `name' with the appropriate permissions
lndev src target
create a symlink from src to target
makedir dir mode
create directory with appropriate mode

* UIDs and GIDs are hardcoded in at MAKEDEV generation time.
(Unfortunately there's not a simple way of determining a GID
a la "id -n user" for determining a UID).

This was tested by generating MAKEDEV for each MACHINE,MACHINE_ARCH
combination and comparing the results of "MAKEDEV all" from the
previous version to the new one.
(This testing actually highlighted mistakes in the previous configuration!)

A driver and user land utility for the Sparkfun Serial Controlled Motor
Driver module as illustrated here:

https://www.sparkfun.com/products/13911

A SCMD module is a ARM SOC simular to a Arduino in front of a motor
driver chip. The single SCMD module can control two motors and up to
16 additional modules can be chained together using an internal I2C
bus. One can interface with the SCMD using tty uart commands, SPI or
I2C. The driver in this commit adds a kernel driver for the I2C and
SPI interfaces. The command line utility provides a set of
convenience commands that support most of the functions of the SCMD
and is able to use the tty uart mode, SPI user land or the included
kernel driver in a uniform manor.

The use of the SCMD module is mostly for small robots and the like,
but it can control anything that is controllable by voltage.

Driver for the Sensirion SHT30/SHT31/SHT35 temperature and humidity
sensor such as:

https://www.adafruit.com/product/2857

This is a higher priced sensor with a lot of features, including the
ability to do sub-second periodic updates. The driver supports
everything about the sensor except for the alert pin.

PR/56452: RVP: MAKEDEV should also create /dev/dri/renderD* devices

efi: Add /dev/efi character device

Introduce a /dev/efi character device that provides a means for accessing
UEFI RT variable services from userland. Compatible with the FreeBSD ioctl
interface for ease of porting their libefivar and associated tools.

The ioctl interface is defined in sys/efiio.h.

To enable support for this on an arch, the kernel needs `pseudo-device efi`
and the MD EFI implementation needs to register its backend by calling
efi_ops_register(). This commit includes an implementation for Arm.

smbios: Add character device for accessing SMBIOS tables

The /dev/smbios character device gives an aperture into physical memory
that allows read-only access to the SMBIOS header and tables.

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.

acpi: add character device for accessing ACPI tables

The /dev/acpi character device gives an aperture into physical memory
that allows only read access to known ACPI tables: RSDP, XSDT/RSDT, and
the root tables. Adapt acpidump(8) to use this interface by default,
falling back to the old /dev/mem method if it is not available or if
ACPIDUMP_USE_DEVMEM=1 is set in the environment. The user visible benefit
of this change is that "options INSECURE" is no longer required to
dump ACPI tables.

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.

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.)

Revert the removal of filemon.

Retire filemon, discussed on tech-kern@.

XXX pullup-9

Replace major number in MAKEDEV for vhci

Add vHCI, a driver which allows to send and receive USB packets directly
from userland via /dev/vhci. Using this, it becomes possible to test and
fuzz the USB stack and all the USB drivers without having the associated
hardware.

The vHCI device has four ports independently addressable.

For each xfer on each port, we create two packets: a setup packet (which
indicates mostly the type of request) and a data packet (which contains
the raw data). These packets are processed by read and write operations
on /dev/vhci: userland poll-reads it to fetch usb_device_request_t
structures, and dispatches the requests depending on bRequest and
bmRequestType.

A few ioctls are available:

VHCI_IOC_GET_INFO - Get the current status
VHCI_IOC_SET_PORT - Choose a vHCI port
VHCI_IOC_USB_ATTACH - Attach a USB device on the current port
VHCI_IOC_USB_DETACH - Detach the USB device on the current port

vHCI has already allowed me to automatically find several bugs in the USB
stack and its drivers.

MAKEDEV.tmpl: Create nodes for 16 USB hubs

As proposed on current-users, but with better formatting.

Raise the number of uhid nodes from 4 to 16.

My keyboard and mouse use multiple device nodes each. I can't use
any other devices once they're attached. With my keyboard, mouse,
and two game controllers attached, a total of 9 nodes are required.

Particularly, high-end keyboards with N-key rollover support require
more device nodes, since they pretend to be multiple keyboards to work
around limitations in the uhid compat spec.

My original intention was to raise it from 4 to 12, but martin
suggested increasing it to 16.

"somewhat insane, but so is reality" - mlelstv

Add experimental userland interface to IPMI driver. Currently, transactions

Actually use unit number for iscsi device.

Add srt(4) to /etc/MAKEDEV and corresponding update to MAKEDEV.8 man page.

Add userland driver to spi framework.

Previously spi would configure the controller to use the lowest speed of
all connected devices since the kernel started and to fail attempted mode
changes. This is now improved to keep individual modes and speeds for each
slave and to reconfigure the controller as necessary for each transfer.

Added man page for spi(9).

Add KCOV - kernel code coverage tracing device

The KCOV driver implements collection of code coverage inside the kernel.
It can be enabled on a per process basis from userland, allowing the kernel
program counter to be collected during syscalls triggered by the same
process.

The device is oriented towards kernel fuzzers, in particular syzkaller.

Currently the only supported coverage type is -fsanitize-coverage=trace-pc.

The KCOV driver was initially developed in Linux. A driver based on the
same concept was then implemented in FreeBSD and OpenBSD.

Documentation is borrowed from OpenBSD and ATF tests from FreeBSD.

This patch has been prepared by Siddharth Muralee, improved by <maxv>
and polished by myself before importing into the mainline tree.

All ATF tests pass.

Remove the satlink driver. It was disabled everywhere, had no man page and
no use either. Spotted by thorpej in PR/21345, ok christos.

Add NVMM - for NetBSD Virtual Machine Monitor -, a kernel driver that

It is made of an MI frontend, to which MD backends can be plugged. One

We install

/usr/include/dev/nvmm/nvmm.h
/usr/include/dev/nvmm/nvmm_ioctl.h
/usr/include/dev/nvmm/{arch}/nvmm_{arch}.h

And the kernel module. For now, the only architecture where we do that
is amd64 (arch=x86).

NVMM is not enabled by default in amd64-GENERIC, but is instead easily
modloadable.

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

Note that while the method here is the same as was discussed on the list,
the actual implementation is free of the typos, and just pure lunacy that
was in the code that was shown there.

Also note these changes are intended to be completely internal, there

a few where foo*) changes to foo|foo[0-9]*) or some other slightly
more complex pattern.

This should prevent "MAKEDEV foobar0" from accidentally matching
the foo* pattern when it should really give an error, and it
should make the order of the patterns less critical.

Add support for the Extensible MIPS ("eMIPS") platform. The
NetBSD/emips port runs on Xilinx and Beecube FPGA systems and the
Giano system simulator.

eMIPS is a platform developed at Microsoft Research for researching
reconfigurable computing. eMIPS allows dynamic loading and scheduling
of application-specific circuits for the purpose of accelerating
computations based on the current workload.

NetBSD eMIPS support for NetBSD 4.x was written at Microsoft Research
by Alessandro Forin and Neil Pittman. Microsoft Corporation has
donated full copyright to The NetBSD Foundation.

Platform support for eMIPS is the first part of Microsoft's
contribution. The second part includes the hardware accelerator
framework and will be proposed on tech-kern soon.

s/07555/0755/ in permissions of /dev file system. Thanks to
Dieter Roelants for the report.

When MAKEDEV creates a memory file system, let it try mount_tmpfs(8)
before falling back to mount_mfs(8). Also calculate required number
of inodes more accurately.

Discussed in tech-userlevel.

In MAKEDEV.tmpl:
* Add a nooutput function to be used instead of redirecting to /dev/null,
because /dev/null might not exist early in the boot sequence. This
should fix a bug in which the pax autodetection failed when used from
init(8) with a read-only root file system without a /dev/null.
* Move most of the main program into a new makedev_main function,
to allow reuse by MAKEDEV.local.

In MAKEDEV.local:
* Use the new makedev_main function defined in MAKEDEV. This allows
MAKEDEV.local to support all the options understood by MAKEDEV, instead
of only a subset. This should fix a bug in which the setup() function
could try to use pax mode even though that was previously not supported.

In MAKEDEV.local man page:
* Update list of command line options.
* Don't explain all the options, just refer to MAKEDEV(8) man page.
* Remove BUGS section now that all MAKEDEV options are supported
by MAKEDEV.local.

* Move duplicated code into a check_pax function, and improve the test
for whether pax is likely to be usable.
* Don't try to create an mfs with fewer than 10 inodes.
* Add a missing exit in an error case.

Pass "-pe" flag to pax, otherwise the devices get created with
permissions modified by the umask.

* MAKEDEV's "-M -M" option was always intended for use only by init(8).
Improve the documentation around that.
* The "-p pax", "-m mknod", and "-s" (mtree specfile) options should
always have been mutually exclusive. Now enforce that.
* The "-f" option didn't ever work with pax or mtree mode; document that,
and make it an error to try something that won't work.
* Make pax mode the default, if no other options prevent this, and if
"pax -w -M" appears to be usable.
* Add missing options to a usage message.

Update some comments and remove an unnecessary eval. No functional change.

Add a linecount shell function, and use it to count the lines in the
output from MAKEDEV.local.

Test whether pax works; if not, fall back to mknod.
This is intended for use on install media that might not have pax.

* Add "-p pax" flag, to create all device nodes at once using pax,
instead of one by one using mknod. This is much faster (speed
increases of up to 20 times have been observed, but 3 to 5 times is
more common).
* One "-M" flag will create the mfs file system but not redirect output
to a temporary console; "-M -M" will also redirect output.
* Change the way we accumulate options to pass to MAKEDEV.local.

Replace hexprint with a version that is much faster for values > 15.
Since I managed to commit my alternate scheme for zeropad, delete

MAKEDEV -M should now output what it is doing.

Remove MAKEDEV.subr. This removes the risk of third party scripts (or
human procedures) breaking because they assume it's enough to copy
MAKEDEV fom one place to another.

Let MAKEDEV return after defining shell functions but before doing any
real work, if MAKEDEV_AS_LIBRARY is set.

Let MAKEDEV.local load MAKEDEV as a function library via
"MAKEDEV_AS_LIBRARY=1 . MAKEDEV".

Add code that can be used by init(1) to request MAKEDEV create a mfs

Determine the actual number of inodes that will be needed and add 10%.
Use "mount_mfs -o union" to save us having to copy MADEDEV (in case
anyone wishes to see it.

If we are called as 'sh MAKEDEV ...', then we would previously have
tried to do '. MAKEDEV.subr'. That doesn't work, we need to do
'. ./MAKEDEV.subr' in that case.

Avoid using dirname(1), which is not available in installation
ramdisk images.

Provide a new MAKEDEV.subr file containing utility functions for
use by both MAKEDEV and MAKEDEV.local. This allows MAKEDEV.local
to accept the same command line arguments as MAKEDEV.

The installed MAKEDEV.subr is generated from MAKEDEV.subr.tmpl.

Replace the licence on MAKEDEV.local with a NetBSD licence, since I
rewrote the entire file.
