Add Atheros SPI controller. This is a "pseudo-controller", as it has some
artificial limitations which really only make it good for use with serial
flash devices. One of the more annoying limitations is a restriction that
it can only transfer 8 bytes at a time. (4 command/address, plus 4 data.)

The driver includes design to work around those limitations, but these
changes are only appropriate for serial flash devices.

This driver is designed to run in interrupt driven mode, but due to lack
of adequate documentation, we run it in polled mode.

A subsequent commit will introduce the MI M25P flash driver, which has been
tested and is known to function somewhat reasonably..

Dynamically calculate the memory size. The math is suspect, but the

Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

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.

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.

Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int. The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER! Some subsystems have

#define min(a, b) ((a) < (b) ? (a) : (b))
#define max(a, b) ((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX. Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate. But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all. (Who knows, maybe in some cases integer
truncation is actually intended!)

This commit provides substantial fixes and functionality for SPI flash.

Specifically, the SPI flash now operates as a nearly fully functional block
device (other than lacking disklabel support). It does some basic translation
stuff, so that if you attempt to write a block, the underlying flash sectors
(usually 64k in size) will be read, erased and rewritten.

To minize thrashing, the spiflash strategy routine attempts to gather writes
to the same sector together, so that in the typical case you will not have to
repeatedly erase/rewrite the sector. It also attempts to check and verify
whether an erase cycle is truly needed. There are still access patterns that
will cause multiple erases to occur, and so I heartily discourage the use
of these flash devices for storing anything other than small configuration
data, or write-once images. If you want to do more than that, then someone
should try to write a real flash translation layer.

The drivers attempt to provide some level of asynchronous operation, so that
while you are erasing or writing to the flash, other things can reasonably
take place.

Note that spiflash does not do bad block remapping. It also doesn't detect
when a device is in read-only mode, or if some sectors are read-only. It
only supports uniform sectored NOR flash. It lacks any code to deal with
disklabels, and does not offer any disk related ioctls.

These limitations aside, it would not be terribly hard, I think, to break
out the code I've done to create a generic "norflash" driver, backed by
a "common" spiflash module. Then other flash drivers (e.g. athflash, etc.)
could benefit from the ability to use this as a block device. I've tried
to architect it to support that, if someone else wants to do the work.
(Hi Jared!)

The primary reason that I've not added code to deal with disklabels is that
I had a difficult time figuring out which framework (disklabels or wedges)
to use, and which bits of code were necessary to implement. In the case of
the flash devices I'm working with, a parser to deal with redboot FIS images
(partitions) would need to be added. I was prepared to do this, but gave
up owing to the complete and total lack of any API or design documentation
pertaining to the requirements for disk drivers and disklabel management or
wedges. I would strongly encourage someone who knows something about
wedges or disklabels to write a simple document (or even a dummy driver)
showing which interfaces should be provided in new mass storage drivers.

This work was funded by the Champaign-Urbana Community Wireless Network
Project.

Add Atheros SPI controller. This is a "pseudo-controller", as it has some
artificial limitations which really only make it good for use with serial
flash devices. One of the more annoying limitations is a restriction that
it can only transfer 8 bytes at a time. (4 command/address, plus 4 data.)

The driver includes design to work around those limitations, but these
changes are only appropriate for serial flash devices.

This driver is designed to run in interrupt driven mode, but due to lack
of adequate documentation, we run it in polled mode.

A subsequent commit will introduce the MI M25P flash driver, which has been
tested and is known to function somewhat reasonably..

Change MII PHY read/write API from:

int (*mii_readreg_t)(device_t, int, int);
void (*mii_writereg_t)(device_t, int, int, int);
to:

int (*mii_readreg_t)(device_t, int, int, uint16_t *);
int (*mii_writereg_t)(device_t, int, int, uint16_t);

Now we can test if a read/write operation failed or not by the return value.

In 802.3 spec says that the PHY shall not respond to read/write transaction
to the unimplemented register(22.2.4.3). Detecting timeout can be used to
check whether a register is implemented or not (if the register conforms to
the spec). ukphy(4) can be used this for MII_MMDACR and MII_MMDAADR.

Note that I noticed that the following code do infinite loop in the
read/wirte function. If it accesses unimplemented PHY register, it will hang.
It should be fixed:

branches: 1.31.2;
Implement the BPF direction filter (BIOC[GS]DIRECTION). It provides backward
compatibility with BIOC[GS]SEESENT ioctl. The userland interface is the same
as FreeBSD.

This change also fixes a bug that the direction is misunderstand on some
environment by passing the direction to bpf_mtap*() instead of checking
m->m_pkthdr.rcvif.

branches: 1.30.14;
Move bpf_mtap and if_ipackets++ on Rx of each driver to percpuq if_input

The benefits of the change are:
- We can reduce codes
- We can provide the same behavior between drivers
- Where/When if_ipackets is counted up
- Note that some drivers still update packet statistics in their own
way (periodical update)
- Moved bpf_mtap run in softint
- This makes it easy to MP-ify bpf

Proposed on tech-kern and tech-net

Apply deferred if_start framework

if_schedule_deferred_start checks if the if_snd queue contains packets,
so drivers don't need to check it by themselves.

branches: 1.28.2;
Introduce m_set_rcvif and m_reset_rcvif

The API is used to set (or reset) a received interface of a mbuf.
They are counterpart of m_get_rcvif, which will come in another
commit, hide internal of rcvif operation, and reduce the diff of
the upcoming change.

No functional change.

Introduce softint-based if_input

This change intends to run the whole network stack in softint context
(or normal LWP), not hardware interrupt context. Note that the work is
still incomplete by this change; to that end, we also have to softint-ify
if_link_state_change (and bpf) which can still run in hardware interrupt.

This change softint-ifies at ifp->if_input that is called from
each device driver (and ieee80211_input) to ensure Layer 2 runs
in softint (e.g., ether_input and bridge_input). To this end,
we provide a framework (called percpuq) that utlizes softint(9)
and percpu ifqueues. With this patch, rxintr of most drivers just
queues received packets and schedules a softint, and the softint
dequeues packets and does rest packet processing.

To minimize changes to each driver, percpuq is allocated in struct
ifnet for now and that is initialized by default (in if_attach).
We probably have to move percpuq to softc of each driver, but it's
future work. At this point, only wm(4) has percpuq in its softc
as a reference implementation.

in the thread at tech-kern@ and tech-net@:

Unify the name of the device property to hold a MAC address - there was

Redefine bpf linkage through an always present op vector, i.e.
#if NBPFILTER is no longer required in the client. This change
doesn't yet add support for loading bpf as a module, since drivers
can register before bpf is attached. However, callers of bpf can
now be modularized.

Dynamically loadable bpf could probably be done fairly easily with
coordination from the stub driver and the real driver by registering
attachments in the stub before the real driver is loaded and doing
a handoff. ... and I'm not going to ponder the depths of unload
here.

Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.

Simplify activation hook.

*** Summary ***

When a link-layer address changes (e.g., ifconfig ex0 link
02:de:ad:be:ef:02 active), send a gratuitous ARP and/or a Neighbor
Advertisement to update the network-/link-layer address bindings
on our LAN peers.

Refuse a change of ethernet address to the address 00:00:00:00:00:00
or to any multicast/broadcast address. (Thanks matt@.)

Reorder ifnet ioctl operations so that driver ioctls may inherit
the functions of their "class"---ether_ioctl(), fddi_ioctl(), et
cetera---and the class ioctls may inherit from the generic ioctl,
ifioctl_common(), but both driver- and class-ioctls may override
the generic behavior. Make network drivers share more code.

Distinguish a "factory" link-layer address from others for the
purposes of both protecting that address from deletion and computing
EUI64.

Return consistent, appropriate error codes from network drivers.

Improve readability. KNF.

*** Details ***

In if_attach(), always initialize the interface ioctl routine,
ifnet->if_ioctl, if the driver has not already initialized it.
Delete if_ioctl == NULL tests everywhere else, because it cannot
happen.

In the ioctl routines of network interfaces, inherit common ioctl
behaviors by calling either ifioctl_common() or whichever ioctl
routine is appropriate for the class of interface---e.g., ether_ioctl()
for ethernets.

Stop (ab)using SIOCSIFADDR and start to use SIOCINITIFADDR. In
the user->kernel interface, SIOCSIFADDR's argument was an ifreq,
but on the protocol->ifnet interface, SIOCSIFADDR's argument was
an ifaddr. That was confusing, and it would work against me as I
make it possible for a network interface to overload most ioctls.
On the protocol->ifnet interface, replace SIOCSIFADDR with
SIOCINITIFADDR. In ifioctl(), return EPERM if userland tries to
invoke SIOCINITIFADDR.

In ifioctl(), give the interface the first shot at handling most
interface ioctls, and give the protocol the second shot, instead
of the other way around. Finally, let compatibility code (COMPAT_OSOCK)
take a shot.

Pull device initialization out of switch statements under
SIOCINITIFADDR. For example, pull ..._init() out of any switch
statement that looks like this:

switch (...->sa_family) {
case ...:
..._init();
...
break;
...
default:
..._init();
...
break;
}

Rewrite many if-else clauses that handle all permutations of IFF_UP
and IFF_RUNNING to use a switch statement,

switch (x & (IFF_UP|IFF_RUNNING)) {
case 0:
...
break;
case IFF_RUNNING:
...
break;
case IFF_UP:
...
break;
case IFF_UP|IFF_RUNNING:
...
break;
}

unifdef lots of code containing #ifdef FreeBSD, #ifdef NetBSD, and
#ifdef SIOCSIFMTU, especially in fwip(4) and in ndis(4).

In ipw(4), remove an if_set_sadl() call that is out of place.

In nfe(4), reuse the jumbo MTU logic in ether_ioctl().

Let ethernets register a callback for setting h/w state such as
promiscuous mode and the multicast filter in accord with a change
in the if_flags: ether_set_ifflags_cb() registers a callback that
returns ENETRESET if the caller should reset the ethernet by calling
if_init(), 0 on success, != 0 on failure. Pull common code from
ex(4), gem(4), nfe(4), sip(4), tlp(4), vge(4) into ether_ioctl(),
and register if_flags callbacks for those drivers.

Return ENOTTY instead of EINVAL for inappropriate ioctls. In
zyd(4), use ENXIO instead of ENOTTY to indicate that the device is
not any longer attached.

Add to if_set_sadl() a boolean 'factory' argument that indicates
whether a link-layer address was assigned by the factory or some
other source. In a comment, recommend using the factory address
for generating an EUI64, and update in6_get_hw_ifid() to prefer a
factory address to any other link-layer address.

Add a routing message, RTM_LLINFO_UPD, that tells protocols to
update the binding of network-layer addresses to link-layer addresses.
Implement this message in IPv4 and IPv6 by sending a gratuitous
ARP or a neighbor advertisement, respectively. Generate RTM_LLINFO_UPD
messages on a change of an interface's link-layer address.

In ether_ioctl(), do not let SIOCALIFADDR set a link-layer address
that is broadcast/multicast or equal to 00:00:00:00:00:00.

Make ether_ioctl() call ifioctl_common() to handle ioctls that it
does not understand.

In gif(4), initialize if_softc and use it, instead of assuming that
the gif_softc and ifp overlap.

Let ifioctl_common() handle SIOCGIFADDR.

Sprinkle rtcache_invariants(), which checks on DIAGNOSTIC kernels
that certain invariants on a struct route are satisfied.

In agr(4), rewrite agr_ioctl_filter() to be a bit more explicit
about the ioctls that we do not allow on an agr(4) member interface.

bzero -> memset. Delete unnecessary casts to void *. Use
sockaddr_in_init() and sockaddr_in6_init(). Compare pointers with
NULL instead of "testing truth". Replace some instances of (type
*)0 with NULL. Change some K&R prototypes to ANSI C, and join
lines.

Prepare for PMF self-suspension: in the if_stop() methods, clear

This change lets the if_stop() routines exit early when they find
on entry that IFF_RUNNING is not set.

To verify that no nasty side effects of duplicate includes (or their

Initial import of AR2315 support, specifically the Meraki Mini (see

to the AR5312 to make it more conducive to sharing code with the AR5315,
and also includes improved early console support.

differences from the AR5312.

No functional change at this time, other than the cpu_model string
(and also sysctl.hw.model node) is changed to reflect the WiSoC cpu
name rather than the identification string in ROM (which tends to not
be very informative.)

Consistently establish / disestablish shutdown hook

Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

Revamp / rework the Atheros MIPS SoC support. Add initial support for the
AR71xx (MIPS 24K core) SoC and the AR9344 (MIPS 74K core) SoC. Force use
of -mips32 for all Atheros kernels. Make code much more common.

Update reference to the Atheros HAL exported headers.

`external/isc/atheros_hal/dist', former `contrib/dev/ath/' is now in cpp(1)'s
include path.

Fix build of MERAKI kernel.

This is a boat-load of changes designed to finish parameterizing the
stuff necessary to separate out AR5312 from AR5315. This includes:

1) rework of arbus IRQs, so that IRQs are now seperately specified
as either MISC or CPU irqs
2) move board/chip-specific addresses into chip-dependent file
3) unencumber argpio from ar5312 specifics, using properties to pass
details such as reset-pin and sysled-pin.
4) an option to select which WiSoC is to be configured is provided.

AR5315 support should be forthcoming shortly now.

branches: 1.1.2;
First pass at cleanup AR5312 WiSoC support to enable better & cleaner
sharing of code with the AR5315, which has many similarities, but many
differences from the AR5312.

No functional change at this time, other than the cpu_model string
(and also sysctl.hw.model node) is changed to reflect the WiSoC cpu
name rather than the identification string in ROM (which tends to not
be very informative.)

Dynamically calculate the memory size. The math is suspect, but the
results are at least accurate. (This was reverse engineered from the
redboot sources, which is one of the reasons why the math is suspect.)

Initial import of AR2315 support, specifically the Meraki Mini (see
the Meraki web site at http://www.meraki.net/ ) This includes changes
to the AR5312 to make it more conducive to sharing code with the AR5315,
and also includes improved early console support.

All devices including ethernet and wlan interfaces on the Meraki Mini are
functional with this port, _except_ SPI flash, which will be introduced
later.

This port was funded by the Champaign-Urbana Communit Wireless Network
Project (CUWiN).

Add AR531X_SYSREG_WDOG_TIMER register. (Forgot to commit this earlier.)

Import new HAL 0.9.17.2. Approved by sam@

New HAL includes some driver changes to register accesses.
Adds support for WLAN devices on AR5312 family devices.
Adds support 32-bit SPARC ath devices (untested).
ath enabled in SPARC64 GENERIC builds.
This HAL is tested and known to work for i386 PCI devices, SPARC64 PCI devices,
and AR5312 WiSoC devices. MIPS PCI devices appear to be busted (possibly only
on Alchemy hardware, unconfirmed), and cardbus support is untested due to
lack of test hardware.

Please report any new problems with this import to garrett@.

Add unified AR531X_REVISION_WMAC.

branches: 1.1.2;
Initial import of Atheros AR531X SoC support. Currently the onboard ethernet
and serial ports are supported, and the system appears stable with an NFS
mounted root. An earlier version of the code was reviewed by simon@, but it
has since had numerous improvements and cleanups.


At the moment, only AR5312 is known to work, but I suspect AR2313 will work
as well. Later 2315/2316 parts are substantially different, and are not yet
supported. Wifi and Marvell switch support found on some designs are not yet
supported.

Platforms known to include AR5312 include Senao Aries 2 (AP5054) and Netgear
WGU624.
