fabc845e37 Remove bogus KASSERT. The 802.11 layer and the resume from suspend
code both seem to call wi_start (directly or via the if_start pointer)
without checking to see if OACTIVE is 0.  In addition, I think that
with the use of 3 transmit buffers this routine can be called with
OACTIVE set, but I might be mistaken about that (and it doesn't
matter).

739804813b Remove bogus UNLOCK in if_wi.c. Since we no longer WILOCK() in the
attach routine, calling WIUNLOCK in the error case of one of the ifs
for that routine is now bogus.  This should have been removed when the
WILOCK() was removed, but wasn't.

1c56cdce18 correct sysctl names and move them to hw.wi: hw.wi.txerate controls the rate

ae06c30e2b Add a comment that says it looks like lucent cards have a primary
firmware revision as well (not sure which firmware versions are needed
for this, but the 6.x and 8.x 'software' versions that I have seem to
support it).

Add dBm comm quality RID.  This is like the normal comm quality rid,
except the signal and noise numbers are normalized to dBm.  Some
revisions of the prism firmware, however, don't support this RID, and
some that do support it return 0 for quality and/or noise.  Your
milage may vary.

073eef8ca2 Add code that will download firmware to a Symbol LA4100-series of CF

Note: This only downloads into the RAM of these cards.  It doesn't
download into FLASH, and is somewhat limited.  There needs to be a
better way to deal, but this works for now.  My Symbol LA4132 CF card

8838e07eeb The 3Com 3CRWE62092A (the XJack antenna product) does not have a host
interface that is compatible with the LUCENT or HERMES firmware.
Instead, it is like the various No Wires Necessary products that were
produced a while ago and then sold to intersil.  It will require a
different driver altogether.  Remove it from the list of supported
cards.

The 3CRWE777A apperas to be a re-badged SMC 2602W card, so the driver
appears to support it.  Add it to the list.

a19c104dd2 Four fixes from NetBSD:
1) Properly detect the Symbol based cards (The 3Com Airconnect and their
   ilk) and only reset them *ONCE* ever.  This appears to make them work,
   but more testing is needed.  The tests that would wedge up my machine
   completely now appear to work, but I have not real access points
   handy.
2) Report both the Station firmware and the Primary firmware on Prism
   based cards.  On Lucent based cards, only report the station firmware
   since that's all it supports.  On symbol cards, report the symbol
   specific firmware name as its station firmware.
3) Better Prism 2.5 and 3 family names.  We really need to go table
   driven for this.
4) Workaround for bugs in Intersil's firmware is only needed for at most
   0.8.2 and earlier, since 0.8.3 and later appear to work.

44731cab3b Change the suser() API to take advantage of td_ucred as well as do a
general cleanup of the API.  The entire API now consists of two functions
similar to the pre-KSE API.  The suser() function takes a thread pointer
as its only argument.  The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0.  The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

90ce56c287 Add the following functions/macros to support byte order conversions and
device drivers for bus system with other endinesses than the CPU (using
interfaces compatible to NetBSD):

- bwap16() and bswap32(). These have optimized implementations on some
  architectures; for those that don't, there exist generic implementations.
- macros to convert from a certain byte order to host byte order and vice
  versa, using a naming scheme like le16toh(), htole16().
  These are implemented using the bswap functions.
- stream bus space access functions, which do not perform a byte order
  conversion (while the normal access functions would if the bus endianess
  differs from the CPU endianess).

htons(), htonl(), ntohs() and ntohl() are implemented using the new
functions above for kernel usage. None of the above interfaces is currently
exported to user land.

Make use of the new functions in a few places where local implementations
of the same functionality existed.

It appears that a number of PrismII card vendors seem to be doing the

but each with their own vendor/product ID. So rather than cut-n-paste
another if statement into the probe routine, it's probably better to

9ed346bab0 Change and clean the mutex lock interface.
mtx_enter(lock, type) becomes:

mtx_lock(lock) for sleep locks (MTX_DEF-initialized locks)
mtx_lock_spin(lock) for spin locks (MTX_SPIN-initialized)

similarily, for releasing a lock, we now have:

mtx_unlock(lock) for MTX_DEF and mtx_unlock_spin(lock) for MTX_SPIN.
We change the caller interface for the two different types of locks
because the semantics are entirely different for each case, and this
makes it explicitly clear and, at the same time, it rids us of the
extra `type' argument.

The enter->lock and exit->unlock change has been made with the idea
that we're "locking data" and not "entering locked code" in mind.

Further, remove all additional "flags" previously passed to the
lock acquire/release routines with the exception of two:

MTX_QUIET and MTX_NOSWITCH

The functionality of these flags is preserved and they can be passed
to the lock/unlock routines by calling the corresponding wrappers:

mtx_{lock, unlock}_flags(lock, flag(s)) and
mtx_{lock, unlock}_spin_flags(lock, flag(s)) for MTX_DEF and MTX_SPIN
locks, respectively.

Re-inline some lock acq/rel code; in the sleep lock case, we only
inline the _obtain_lock()s in order to ensure that the inlined code
fits into a cache line. In the spin lock case, we inline recursion and
actually only perform a function call if we need to spin. This change
has been made with the idea that we generally tend to avoid spin locks
and that also the spin locks that we do have and are heavily used
(i.e. sched_lock) do recurse, and therefore in an effort to reduce
function call overhead for some architectures (such as alpha), we
inline recursion for this case.

Create a new malloc type for the witness code and retire from using
the M_DEV type. The new type is called M_WITNESS and is only declared
if WITNESS is enabled.

Begin cleaning up some machdep/mutex.h code - specifically updated the
"optimized" inlined code in alpha/mutex.h and wrote MTX_LOCK_SPIN
and MTX_UNLOCK_SPIN asm macros for the i386/mutex.h as we presently
need those.

Finally, caught up to the interface changes in all sys code.

08812b3925 Implement MTX_RECURSE flag for mtx_init().
All calls to mtx_init() for mutexes that recurse must now include
the MTX_RECURSE bit in the flag argument variable. This change is in
preparation for an upcoming (further) mutex API cleanup.
The witness code will call panic() if a lock is found to recurse but
the MTX_RECURSE bit was not set during the lock's initialization.

The old MTX_RECURSE "state" bit (in mtx_lock) has been renamed to
MTX_RECURSED, which is more appropriate given its meaning.

The following locks have been made "recursive," thus far:
eventhandler, Giant, callout, sched_lock, possibly some others declared
in the architecture-specific code, all of the network card driver locks
in pci/, as well as some other locks in dev/ stuff that I've found to
be recursive.

664a31e496 Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot).  This is consistant with the other
BSD's who made this change quite some time ago.  More commits to come.

dda0e6f54e Update the WaveLAN/IEEE driver:
- Convert to new bus attachment scheme. Thanks to Blaz Zupan for doing
  the initial work here. One thing I changed was to have the attach
  and detach routines work like the PCI drivers, which means that in
  theory you should be able to load and unload the driver like the PCI
  NIC drivers, however the pccard support for this hasn't settled down
  yet so it doesn't quite work. Once the pccard work is done, I'll have
  to revisit this.

- Add device wi0 to PCCARD. If we're lucky, people should be able to
  install via their WaveLAN cards now.

- Add support for signal strength caching. The wicontrol utility has
  also been updated to allow zeroing and displaying the signal strength
  cache.

- Add a /sys/modules/wi directory and fix a Makefile to builf if_wi.ko.
  Currently this module is only built for the i386 platform, though once
  the pccard stuff is done it should be able to work on the alpha too.
  (Theoretically you should be able to plug one of the WaveLAN/IEEE ISA
  cards into an alpha with an ISA slot, but we'll see how that turns out.

- Update LINT to use only device wi0. There is no true ISA version of
  the WaveLAN/IEEE so we'll never use an ISA attachment.

- Update files.i386 so that if_wi is dependent on card.

98a229f65e As suggested by phk, unconditionalize BPF support in these drivers. Since
there are stubs compiled into the kernel if BPF support is not enabled,
there aren't any problems with unresolved symbols. The modules in /modules
are compiled with BPF support enabled anyway, so the most this will do is
bloat GENERIC a little.

fcb893a801 Implement a new generic mechanism for attaching handler functions to
events, in order to pave the way for removing a number of the ad-hoc
implementations currently in use.

Retire the at_shutdown family of functions and replace them with
new event handler lists.

Rework kern_shutdown.c to take greater advantage of the use of event
handlers.

7694cd9368 Correct the alignment of some of the members in the wi_frame structure.
The structure is the right length, but some of the members (notably
wi_q_info) were off a bit. This causes the received signal strength
values to appear bogus.

f30fba37d7 Patch the WaveLAN/IEEE driver to detect and reject oversized received
frames (or just insane received packet lengths generated due to errors
reading from the NIC's internal buffers). Anything too large to fit
safely into an mbuf cluster buffer is discarded and an error logged.

I have not observed this problem with my own cards, but on user has
reported it and adding the sanity test seems reasonable in any case.

e566363ef1 Modify wicontrol(8) and wi(4) to allow setting the frequency of the
WaveLAN's radio modem. The default is whatever the NIC uses since NICs
sold in different countries may default to different frequencies. (The
Lose95/LoseNT software doesn't let you select the channel so it's probably
not really meant to be changed.)

31a08ab08e Add device driver support for the Lucent WaveLAN/IEEE 802.11 PCMCIA
adapter (and some workalikes). Also add man pages and a wicontrol
utility to manipulate some of the card parameters.

This driver was written using information gleaned from the Lucent HCF Light
library, though it does not use any of the HCF Light code itself, mainly
because it's contaminated by the GPL (but also because it's pretty gross).
The HCF Light lacks certain featurs from the full (but proprietary) HCF
library, including 802.11 frame encapsulation support, however it has
just enough register information about the Hermes chip to allow someone
with enough spare time and energy to implement a proper driver. (I would
have prefered getting my hands on the Hermes manual, but that's proprietary
too. For those who are wondering, the Linux driver uses the proprietary
HCF library, but it's provided in object code form only.)

Note that I do not have access to a WavePOINT access point, so I have
only been able to test ad-hoc mode. The wicontrol utility can turn on
BSS mode, but I don't know for certain that the NIC will associate with
an access point correctly. Testers are encouraged to send their results
to me so that I can find out if I screwed up or not.

113a394c06 Add device driver support for the Lucent WaveLAN/IEEE 802.11 wireless
network adapters. These are all PCMCIA devices (the ISA version is a
PCMCIA to ISA bridge with a PCMCIA card plugged into it). Also add a
wicontrol utility to read and write some of the card's parameters.

Note: I do not have access to a WavePOINT access point, so I have only
been able to test this driver in ad-hoc (point to point) mode. The
wicontrol utility allows programming the desired service set name (SSID)
and enabling BSS mode, but I can't tell for sure if it works (I know the
card switches modes, but I can't verify that it joins a service set
correctly).

This driver was written using information gleaned from the Lucent HCF Light
library, which is an API library designed to simplify driver development
for devices based on the Lucent Hermes chip. Unfortunately, the HCF Light
is missing certain features (like 802.11 frame encapsulation!) which are
available only in the proprietary complete HCF code, which is not available
to the public. This driver uses none of the HCF Light code: it's very ugly
and contaminated by the GPL. IP and ARP packets are encapsulated as 802.11
frames, everything else is encapsulated as 802.3.

(It would be easier to just get the Hermes programming manual, but that's
not publically available either. For those who are wondering, the Linux
WaveLAN/IEEE driver uses the proprietary HCF code, which is provided in
object code form only. So much for supporting open source sofware.)

Multicast filter support is implemented, however it appears that the
filter doesn't work: programming in one IP mutlicast group enables them
all.
