uhidev(9): New uhidev_write_async.
Like uhidev_write but issues the transfer asynchronously with a callback.
Use it in ucycom(4).
Also, clear endpoint stalls asynchronously -- can't do them synchronously in xfer callbacks which run at softint and therefore can't wait in cv_wait as usbd_do_request does.

uhidev(9): Partially fix uhidev_write aborting.
In my previous change, I intended to make uhidev_stop abort any pending write -- but I forgot to initialize sc->sc_writereportid, so it never did anything.
This changes the API and ABI of uhidev_write so it takes the struct uhidev pointer, rather than the struct uhidev_softc pointer; this way uhidev_write knows what the report id of the client is, so it can arrange to have uhidev_stop abort only this one.
XXX Except it still doesn't actually work because we do this unlocked, ugh, so the write might complete before we abort anything. To be fixed some more in a later change.
XXX kernel ABI change to uhidev_write signature, used by uhidev driver modules, requires bump

usb: Overhaul uhid(4) and uhidev(4) locking.
- uhidev API rules:
1. Call uhidev_open when you want exclusive use of a report id. After it succeeds, you will get interrupts.
2. Call uhidev_close when done with exclusive use of a report id. After it returns, you will no longer get interrupts.
=> uhidev_open/close do not nest.
3. uhidev_write no longer requires the caller to have exclusive access -- if there is a write in progress, it will block interruptibly until done. This way drivers for individual report ids need not work separately to coordinate their writes.
4. You must uhidev_stop to abort any pending writes on the same report id. (uhidev_stop no longer does anything else -- to ensure no more interrupts, just use uhidev_close.)
- Fix uhidev_open/close locking -- uhidev now has an interruptible config lock held only on first open and last close by any report id in the device, to serialize the transition between zero and nonzero numbers of references which requires opening/closing pipes and allocating/freeing buffers.
- Make /dev/uhidN selnotify(POLLHUP) when the device is yanked.
- Factor uhid device lookup and reference counting and dying detection and so on into uhid_enter/exit.
- Nix struct uhid_softc::sc_access_lock. This served no purpose but to confuse me when trying to understand the logic of this beast (and to ensure uhidev_write exclusion, but it was uninterruptible, which is wrong for something that implements userland operations, and didn't actually work because uhidev_write did nothing to coordinate between different report ids).
- Fix locking in select/poll.
- Use atomics to manage UHID_IMMED to keep it simple. (sc_lock would be fine too but it makes the code more verbose.)
- Omit needless UHID_ASLP -- cv_broadcast already has this micro-optimization.
With these changes, my Pinebook survives
for i in `jot 100`; do echo '###' $i for j in `jot 16`; do usbhidctl -rf /dev/uhid$j >/dev/null & done wait done
while plugging and unplugging uhid(4) devices (U2F keys), and the U2F keys still work as U2F keys.
ok nick, mrg
XXX pullup-9 XXX pullup-8?
Note on ABI and pullups: This changes the layout of struct uhidev_softc, but with the sole exception of ucycom(4) -- which at the moment is completely broken and unusable -- the only members that USB HID drivers use are sc_udev and sc_iface, which haven't changed. The layout of struct uhidev, which is allocated by each USB HID driver in its own softc structure, is unchanged.

branches: 1.13.2; 1.13.4; merge the jmcneill-usbmp branch. many thanks to jared for the initial work, and every one else who has tested things for me. this is largely my fault at this point :-)
the main changes are something like:
- usbd_bus_methods{} gains a get_lock() to enable the host controller to provide a lock for the USB code. if the lock isn't provided, old-style protection is (partially) applied.
- ehci/ohci/uhci have been converted to the new interfaces, including mutex/cv/etc conversion.
- usbdivar.h contains a discussion about locking and what locks are held for which method calls. more to come for usbdi(9) here.
- audio drivers (uaudio, umidi, auvitek) have been properly SMPified now that USB is ready.
- scsi drivers have been modified to take the kernel lock explicitly before calling into scsi code.
- usb pipes are associated with a lock, that is the same as the controller lock. (this could be split up further in the future.)
- several usbfoo_locked() or usbfoo_unlocked() functions have been added to the usbdi(9) to enable functionality with or without the USB lock (per controller) already being held.
the TODO.usbmp file has specific details on what is left to do, including what device-specific changes should be done now that the whole framework is ready.

Entropy-pool implementation move and cleanup.
1) Move core entropy-pool code and source/sink/sample management code to sys/kern from sys/dev.
2) Remove use of NRND as test for presence of entropy-pool code throughout source tree.
3) Remove use of RND_ENABLED in device drivers as microoptimization to avoid expensive operations on disabled entropy sources; make the rnd_add calls do this directly so all callers benefit.
4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might have lead to slight entropy overestimation for some sources.
5) Add new source types for environmental sensors, power sensors, VM system events, and skew between clocks, with a sample implementation for each.
ok releng to go in before the branch due to the difficulty of later pullup (widespread #ifdef removal and moved files). Tested with release builds on amd64 and evbarm and live testing on amd64.

branches: 1.11.2; First step of random number subsystem rework described in <20111022023242.BA26F14A158@mail.netbsd.org>. This change includes the following:
An initial cleanup and minor reorganization of the entropy pool code in sys/dev/rnd.c and sys/dev/rndpool.c. Several bugs are fixed. Some effort is made to accumulate entropy more quickly at boot time.
A generic interface, "rndsink", is added, for stream generators to request that they be re-keyed with good quality entropy from the pool as soon as it is available.
The arc4random()/arc4randbytes() implementation in libkern is adjusted to use the rndsink interface for rekeying, which helps address the problem of low-quality keys at boot time.
An implementation of the FIPS 140-2 statistical tests for random number generator quality is provided (libkern/rngtest.c). This is based on Greg Rose's implementation from Qualcomm.
A new random stream generator, nist_ctr_drbg, is provided. It is based on an implementation of the NIST SP800-90 CTR_DRBG by Henric Jungheim. This generator users AES in a modified counter mode to generate a backtracking-resistant random stream.
An abstraction layer, "cprng", is provided for in-kernel consumers of randomness. The arc4random/arc4randbytes API is deprecated for in-kernel use. It is replaced by "cprng_strong". The current cprng_fast implementation wraps the existing arc4random implementation. The current cprng_strong implementation wraps the new CTR_DRBG implementation. Both interfaces are rekeyed from the entropy pool automatically at intervals justifiable from best current cryptographic practice.
In some quick tests, cprng_fast() is about the same speed as the old arc4randbytes(), and cprng_strong() is about 20% faster than rnd_extract_data(). Performance is expected to improve.
The AES code in src/crypto/rijndael is no longer an optional kernel component, as it is required by cprng_strong, which is not an optional kernel component.
The entropy pool output is subjected to the rngtest tests at startup time; if it fails, the system will reboot. There is approximately a 3/10000 chance of a false positive from these tests. Entropy pool _input_ from hardware random numbers is subjected to the rngtest tests at attach time, as well as the FIPS continuous-output test, to detect bad or stuck hardware RNGs; if any are detected, they are detached, but the system continues to run.
A problem with rndctl(8) is fixed -- datastructures with pointers in arrays are no longer passed to userspace (this was not a security problem, but rather a major issue for compat32). A new kernel will require a new rndctl.
The sysctl kern.arandom() and kern.urandom() nodes are hooked up to the new generators, but the /dev/*random pseudodevices are not, yet.
Manual pages for the new kernel interfaces are forthcoming.

This will allow to enforce some rules, eg that the former don't use interface information for matching or that the latter don't modify global device state. The previous way left too much freedom do the drivers which led to inconsistencies and abuse. For now, I've not changed locators and submatch rules, this will happen later. There should not be any change in behaviour, except in the case of some drivers which did behave inconsistently: if_atu, if_axe, uep: matched the configured device in the interface stage, but did configuration again. I've converted them to match in the device stage. ustir, utoppy: matched in the interface stage, but only against vendor/device information, and used any configuration/interface without checking. Changed to match in device stage, and added some simple code to configure and use the first interface. If you have one of those devices, please test!

Introduce an extra driver level for HID devices, uhidev. This uhidev driver attaches to the hub, and HID drivers (ums, ukbd, and uhid) attach to uhidev. The reason for this change is that some HID devices report multiple components (like a keyboard and a mouse) using the same interface, but with different report identifiers. The report identifier can be specified with a locator for the HID drivers. Furthermore, change the ukbd driver to handle other formats than the boot protocol.

usb: Overhaul uhid(4) and uhidev(4) locking.
- uhidev API rules:
1. Call uhidev_open when you want exclusive use of a report id. After it succeeds, you will get interrupts.
2. Call uhidev_close when done with exclusive use of a report id. After it returns, you will no longer get interrupts.
=> uhidev_open/close do not nest.
3. uhidev_write no longer requires the caller to have exclusive access -- if there is a write in progress, it will block interruptibly until done. This way drivers for individual report ids need not work separately to coordinate their writes.
4. You must uhidev_stop to abort any pending writes on the same report id. (uhidev_stop no longer does anything else -- to ensure no more interrupts, just use uhidev_close.)
- Fix uhidev_open/close locking -- uhidev now has an interruptible config lock held only on first open and last close by any report id in the device, to serialize the transition between zero and nonzero numbers of references which requires opening/closing pipes and allocating/freeing buffers.
- Make /dev/uhidN selnotify(POLLHUP) when the device is yanked.
- Factor uhid device lookup and reference counting and dying detection and so on into uhid_enter/exit.
- Nix struct uhid_softc::sc_access_lock. This served no purpose but to confuse me when trying to understand the logic of this beast (and to ensure uhidev_write exclusion, but it was uninterruptible, which is wrong for something that implements userland operations, and didn't actually work because uhidev_write did nothing to coordinate between different report ids).
- Fix locking in select/poll.
- Use atomics to manage UHID_IMMED to keep it simple. (sc_lock would be fine too but it makes the code more verbose.)
- Omit needless UHID_ASLP -- cv_broadcast already has this micro-optimization.
With these changes, my Pinebook survives
for i in `jot 100`; do echo '###' $i for j in `jot 16`; do usbhidctl -rf /dev/uhid$j >/dev/null & done wait done
while plugging and unplugging uhid(4) devices (U2F keys), and the U2F keys still work as U2F keys.
ok nick, mrg
XXX pullup-9 XXX pullup-8?
Note on ABI and pullups: This changes the layout of struct uhidev_softc, but with the sole exception of ucycom(4) -- which at the moment is completely broken and unusable -- the only members that USB HID drivers use are sc_udev and sc_iface, which haven't changed. The layout of struct uhidev, which is allocated by each USB HID driver in its own softc structure, is unchanged.

branches: 1.13.2; 1.13.4; merge the jmcneill-usbmp branch. many thanks to jared for the initial work, and every one else who has tested things for me. this is largely my fault at this point :-)
the main changes are something like:
- usbd_bus_methods{} gains a get_lock() to enable the host controller to provide a lock for the USB code. if the lock isn't provided, old-style protection is (partially) applied.
- ehci/ohci/uhci have been converted to the new interfaces, including mutex/cv/etc conversion.
- usbdivar.h contains a discussion about locking and what locks are held for which method calls. more to come for usbdi(9) here.
- audio drivers (uaudio, umidi, auvitek) have been properly SMPified now that USB is ready.
- scsi drivers have been modified to take the kernel lock explicitly before calling into scsi code.
- usb pipes are associated with a lock, that is the same as the controller lock. (this could be split up further in the future.)
- several usbfoo_locked() or usbfoo_unlocked() functions have been added to the usbdi(9) to enable functionality with or without the USB lock (per controller) already being held.
the TODO.usbmp file has specific details on what is left to do, including what device-specific changes should be done now that the whole framework is ready.

Entropy-pool implementation move and cleanup.
1) Move core entropy-pool code and source/sink/sample management code to sys/kern from sys/dev.
2) Remove use of NRND as test for presence of entropy-pool code throughout source tree.
3) Remove use of RND_ENABLED in device drivers as microoptimization to avoid expensive operations on disabled entropy sources; make the rnd_add calls do this directly so all callers benefit.
4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might have lead to slight entropy overestimation for some sources.
5) Add new source types for environmental sensors, power sensors, VM system events, and skew between clocks, with a sample implementation for each.
ok releng to go in before the branch due to the difficulty of later pullup (widespread #ifdef removal and moved files). Tested with release builds on amd64 and evbarm and live testing on amd64.

branches: 1.11.2; First step of random number subsystem rework described in <20111022023242.BA26F14A158@mail.netbsd.org>. This change includes the following:
An initial cleanup and minor reorganization of the entropy pool code in sys/dev/rnd.c and sys/dev/rndpool.c. Several bugs are fixed. Some effort is made to accumulate entropy more quickly at boot time.
A generic interface, "rndsink", is added, for stream generators to request that they be re-keyed with good quality entropy from the pool as soon as it is available.
The arc4random()/arc4randbytes() implementation in libkern is adjusted to use the rndsink interface for rekeying, which helps address the problem of low-quality keys at boot time.
An implementation of the FIPS 140-2 statistical tests for random number generator quality is provided (libkern/rngtest.c). This is based on Greg Rose's implementation from Qualcomm.
A new random stream generator, nist_ctr_drbg, is provided. It is based on an implementation of the NIST SP800-90 CTR_DRBG by Henric Jungheim. This generator users AES in a modified counter mode to generate a backtracking-resistant random stream.
An abstraction layer, "cprng", is provided for in-kernel consumers of randomness. The arc4random/arc4randbytes API is deprecated for in-kernel use. It is replaced by "cprng_strong". The current cprng_fast implementation wraps the existing arc4random implementation. The current cprng_strong implementation wraps the new CTR_DRBG implementation. Both interfaces are rekeyed from the entropy pool automatically at intervals justifiable from best current cryptographic practice.
In some quick tests, cprng_fast() is about the same speed as the old arc4randbytes(), and cprng_strong() is about 20% faster than rnd_extract_data(). Performance is expected to improve.
The AES code in src/crypto/rijndael is no longer an optional kernel component, as it is required by cprng_strong, which is not an optional kernel component.
The entropy pool output is subjected to the rngtest tests at startup time; if it fails, the system will reboot. There is approximately a 3/10000 chance of a false positive from these tests. Entropy pool _input_ from hardware random numbers is subjected to the rngtest tests at attach time, as well as the FIPS continuous-output test, to detect bad or stuck hardware RNGs; if any are detected, they are detached, but the system continues to run.
A problem with rndctl(8) is fixed -- datastructures with pointers in arrays are no longer passed to userspace (this was not a security problem, but rather a major issue for compat32). A new kernel will require a new rndctl.
The sysctl kern.arandom() and kern.urandom() nodes are hooked up to the new generators, but the /dev/*random pseudodevices are not, yet.
Manual pages for the new kernel interfaces are forthcoming.

This will allow to enforce some rules, eg that the former don't use interface information for matching or that the latter don't modify global device state. The previous way left too much freedom do the drivers which led to inconsistencies and abuse. For now, I've not changed locators and submatch rules, this will happen later. There should not be any change in behaviour, except in the case of some drivers which did behave inconsistently: if_atu, if_axe, uep: matched the configured device in the interface stage, but did configuration again. I've converted them to match in the device stage. ustir, utoppy: matched in the interface stage, but only against vendor/device information, and used any configuration/interface without checking. Changed to match in device stage, and added some simple code to configure and use the first interface. If you have one of those devices, please test!

Introduce an extra driver level for HID devices, uhidev. This uhidev driver attaches to the hub, and HID drivers (ums, ukbd, and uhid) attach to uhidev. The reason for this change is that some HID devices report multiple components (like a keyboard and a mouse) using the same interface, but with different report identifiers. The report identifier can be specified with a locator for the HID drivers. Furthermore, change the ukbd driver to handle other formats than the boot protocol.

branches: 1.13.2; 1.13.4; merge the jmcneill-usbmp branch. many thanks to jared for the initial work, and every one else who has tested things for me. this is largely my fault at this point :-)
the main changes are something like:
- usbd_bus_methods{} gains a get_lock() to enable the host controller to provide a lock for the USB code. if the lock isn't provided, old-style protection is (partially) applied.
- ehci/ohci/uhci have been converted to the new interfaces, including mutex/cv/etc conversion.
- usbdivar.h contains a discussion about locking and what locks are held for which method calls. more to come for usbdi(9) here.
- audio drivers (uaudio, umidi, auvitek) have been properly SMPified now that USB is ready.
- scsi drivers have been modified to take the kernel lock explicitly before calling into scsi code.
- usb pipes are associated with a lock, that is the same as the controller lock. (this could be split up further in the future.)
- several usbfoo_locked() or usbfoo_unlocked() functions have been added to the usbdi(9) to enable functionality with or without the USB lock (per controller) already being held.
the TODO.usbmp file has specific details on what is left to do, including what device-specific changes should be done now that the whole framework is ready.

Entropy-pool implementation move and cleanup.
1) Move core entropy-pool code and source/sink/sample management code to sys/kern from sys/dev.
2) Remove use of NRND as test for presence of entropy-pool code throughout source tree.
3) Remove use of RND_ENABLED in device drivers as microoptimization to avoid expensive operations on disabled entropy sources; make the rnd_add calls do this directly so all callers benefit.
4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might have lead to slight entropy overestimation for some sources.
5) Add new source types for environmental sensors, power sensors, VM system events, and skew between clocks, with a sample implementation for each.
ok releng to go in before the branch due to the difficulty of later pullup (widespread #ifdef removal and moved files). Tested with release builds on amd64 and evbarm and live testing on amd64.

branches: 1.11.2; First step of random number subsystem rework described in <20111022023242.BA26F14A158@mail.netbsd.org>. This change includes the following:
An initial cleanup and minor reorganization of the entropy pool code in sys/dev/rnd.c and sys/dev/rndpool.c. Several bugs are fixed. Some effort is made to accumulate entropy more quickly at boot time.
A generic interface, "rndsink", is added, for stream generators to request that they be re-keyed with good quality entropy from the pool as soon as it is available.
The arc4random()/arc4randbytes() implementation in libkern is adjusted to use the rndsink interface for rekeying, which helps address the problem of low-quality keys at boot time.
An implementation of the FIPS 140-2 statistical tests for random number generator quality is provided (libkern/rngtest.c). This is based on Greg Rose's implementation from Qualcomm.
A new random stream generator, nist_ctr_drbg, is provided. It is based on an implementation of the NIST SP800-90 CTR_DRBG by Henric Jungheim. This generator users AES in a modified counter mode to generate a backtracking-resistant random stream.
An abstraction layer, "cprng", is provided for in-kernel consumers of randomness. The arc4random/arc4randbytes API is deprecated for in-kernel use. It is replaced by "cprng_strong". The current cprng_fast implementation wraps the existing arc4random implementation. The current cprng_strong implementation wraps the new CTR_DRBG implementation. Both interfaces are rekeyed from the entropy pool automatically at intervals justifiable from best current cryptographic practice.
In some quick tests, cprng_fast() is about the same speed as the old arc4randbytes(), and cprng_strong() is about 20% faster than rnd_extract_data(). Performance is expected to improve.
The AES code in src/crypto/rijndael is no longer an optional kernel component, as it is required by cprng_strong, which is not an optional kernel component.
The entropy pool output is subjected to the rngtest tests at startup time; if it fails, the system will reboot. There is approximately a 3/10000 chance of a false positive from these tests. Entropy pool _input_ from hardware random numbers is subjected to the rngtest tests at attach time, as well as the FIPS continuous-output test, to detect bad or stuck hardware RNGs; if any are detected, they are detached, but the system continues to run.
A problem with rndctl(8) is fixed -- datastructures with pointers in arrays are no longer passed to userspace (this was not a security problem, but rather a major issue for compat32). A new kernel will require a new rndctl.
The sysctl kern.arandom() and kern.urandom() nodes are hooked up to the new generators, but the /dev/*random pseudodevices are not, yet.
Manual pages for the new kernel interfaces are forthcoming.

branches: 1.7.32; 1.7.34; 1.7.36; Introduce different autoconf interface attributes for USB drivers matching (and handling) a whole device and those which match an interface only. This will allow to enforce some rules, eg that the former don't use interface information for matching or that the latter don't modify global device state. The previous way left too much freedom do the drivers which led to inconsistencies and abuse. For now, I've not changed locators and submatch rules, this will happen later. There should not be any change in behaviour, except in the case of some drivers which did behave inconsistently: if_atu, if_axe, uep: matched the configured device in the interface stage, but did configuration again. I've converted them to match in the device stage. ustir, utoppy: matched in the interface stage, but only against vendor/device information, and used any configuration/interface without checking. Changed to match in device stage, and added some simple code to configure and use the first interface. If you have one of those devices, please test!

Introduce an extra driver level for HID devices, uhidev. This uhidev driver attaches to the hub, and HID drivers (ums, ukbd, and uhid) attach to uhidev. The reason for this change is that some HID devices report multiple components (like a keyboard and a mouse) using the same interface, but with different report identifiers. The report identifier can be specified with a locator for the HID drivers. Furthermore, change the ukbd driver to handle other formats than the boot protocol.

- several usbfoo_locked() or usbfoo_unlocked() functions have been added to the usbdi(9) to enable functionality with or without the USB lock (per controller) already being held.
the TODO.usbmp file has specific details on what is left to do, including what device-specific changes should be done now that the whole framework is ready.

Entropy-pool implementation move and cleanup.
1) Move core entropy-pool code and source/sink/sample management code to sys/kern from sys/dev.
2) Remove use of NRND as test for presence of entropy-pool code throughout source tree.
3) Remove use of RND_ENABLED in device drivers as microoptimization to avoid expensive operations on disabled entropy sources; make the rnd_add calls do this directly so all callers benefit.
4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might have lead to slight entropy overestimation for some sources.
5) Add new source types for environmental sensors, power sensors, VM system events, and skew between clocks, with a sample implementation for each.
ok releng to go in before the branch due to the difficulty of later pullup (widespread #ifdef removal and moved files). Tested with release builds on amd64 and evbarm and live testing on amd64.

branches: 1.11.2; First step of random number subsystem rework described in <20111022023242.BA26F14A158@mail.netbsd.org>. This change includes the following:
An initial cleanup and minor reorganization of the entropy pool code in sys/dev/rnd.c and sys/dev/rndpool.c. Several bugs are fixed. Some effort is made to accumulate entropy more quickly at boot time.
A generic interface, "rndsink", is added, for stream generators to request that they be re-keyed with good quality entropy from the pool as soon as it is available.
The arc4random()/arc4randbytes() implementation in libkern is adjusted to use the rndsink interface for rekeying, which helps address the problem of low-quality keys at boot time.
An implementation of the FIPS 140-2 statistical tests for random number generator quality is provided (libkern/rngtest.c). This is based on Greg Rose's implementation from Qualcomm.
A new random stream generator, nist_ctr_drbg, is provided. It is based on an implementation of the NIST SP800-90 CTR_DRBG by Henric Jungheim. This generator users AES in a modified counter mode to generate a backtracking-resistant random stream.
An abstraction layer, "cprng", is provided for in-kernel consumers of randomness. The arc4random/arc4randbytes API is deprecated for in-kernel use. It is replaced by "cprng_strong". The current cprng_fast implementation wraps the existing arc4random implementation. The current cprng_strong implementation wraps the new CTR_DRBG implementation. Both interfaces are rekeyed from the entropy pool automatically at intervals justifiable from best current cryptographic practice.
In some quick tests, cprng_fast() is about the same speed as the old arc4randbytes(), and cprng_strong() is about 20% faster than rnd_extract_data(). Performance is expected to improve.
The AES code in src/crypto/rijndael is no longer an optional kernel component, as it is required by cprng_strong, which is not an optional kernel component.
The entropy pool output is subjected to the rngtest tests at startup time; if it fails, the system will reboot. There is approximately a 3/10000 chance of a false positive from these tests. Entropy pool _input_ from hardware random numbers is subjected to the rngtest tests at attach time, as well as the FIPS continuous-output test, to detect bad or stuck hardware RNGs; if any are detected, they are detached, but the system continues to run.
A problem with rndctl(8) is fixed -- datastructures with pointers in arrays are no longer passed to userspace (this was not a security problem, but rather a major issue for compat32). A new kernel will require a new rndctl.
The sysctl kern.arandom() and kern.urandom() nodes are hooked up to the new generators, but the /dev/*random pseudodevices are not, yet.
Manual pages for the new kernel interfaces are forthcoming.

branches: 1.7.32; 1.7.34; 1.7.36; Introduce different autoconf interface attributes for USB drivers matching (and handling) a whole device and those which match an interface only. This will allow to enforce some rules, eg that the former don't use interface information for matching or that the latter don't modify global device state. The previous way left too much freedom do the drivers which led to inconsistencies and abuse. For now, I've not changed locators and submatch rules, this will happen later. There should not be any change in behaviour, except in the case of some drivers which did behave inconsistently: if_atu, if_axe, uep: matched the configured device in the interface stage, but did configuration again. I've converted them to match in the device stage. ustir, utoppy: matched in the interface stage, but only against vendor/device information, and used any configuration/interface without checking. Changed to match in device stage, and added some simple code to configure and use the first interface. If you have one of those devices, please test!

Add the ability to force ugen to attach with very high priority if "flags 1" is specified. This can be used with the vendor and product locators to force ugen to be used for certain devices. Similarly, uhid only attaches if no other HID driver (ums or ukbd) wants it. Again, "flags 1" will force uhid to attach anyway.

Introduce an extra driver level for HID devices, uhidev. This uhidev driver attaches to the hub, and HID drivers (ums, ukbd, and uhid) attach to uhidev. The reason for this change is that some HID devices report multiple components (like a keyboard and a mouse) using the same interface, but with different report identifiers. The report identifier can be specified with a locator for the HID drivers. Furthermore, change the ukbd driver to handle other formats than the boot protocol.
