I only generally test on RHEL 4 when testing against kernels older
than 2.6.18. Apparently OpenSUSE 10.1 runs with 2.6.16 and doesn't
have WARN_ON_ONCE backported. I took the patch Richard Miller
originally attached to the issue and moved it to
include/dahdi/kernel.h so it would be available for all the board
drivers in the future.

Uses the linecompat member to determine what type of span it is. This will
allow removing T1/E1 flags from other places where the span type is stored.
This function also changes the return value from bool to int for the
inlines defined in include/dahdi/kernel.h. This is because not all
kernel versions include stdbool.h in the headers and it will conflict
with boolean values that are exported via module parameters on some
older kernels if dahdi included it globally.

HAVE_NET_DEVICE_OPS was defined in the mainline kernel in commit
47fd5b83 which was first released in 2.6.29. Any kernels after that will
have those fields defined.
Mainline commit e2270ea62ae4d7a removed the feature test macros, so
the easiest thing to do is define HAVE_NET_DEVICE_OPS ourselves on the
kernels since it was committed.
This change is needed to compile against the 3.1 kernel.

dahdi_ec_chunk is the function that saves the received audio and places
a signed linear copy of it in the pre echocanceled buffer on the
channel. By splitting the input and output of this function into two
parameters, a driver that can provide separate pre and post ec streams
can pass them independently to DAHDI, without worrying about DAHDI
overwriting a stream that may have already been echocanceled by the
hardware.
Previously, the dahdi_ec_chunk interface took a received audio buffer
and overwrote it after canceling the echo. Now the input and output
from the function are broken up in order to support hardware echocans
that have a different preechocan stream.

This change ensures that the dahdi_span_ops callbacks are not called
with any spinlocks held, and that the module is pinned in memory, and
also passes the struct file * pointer to the callbacks.
Passing the file pointer to the callbacks allows the board drivers to
check any flags on the file descriptor used to configure the
span/channel. The intent here is to allow dahdi_config to open the
/dev/dahdi/ctl file in a non-blocking mode in case there is a lengthy
processes that needs to happen as part of configuration.

* Separate out device generation in dahdi_[un]register to separate

* As we don't keep anywhere the information of whether or not

an existing device node for a channel, I abuse an unused flag:
DAHDI_FLAGBIT_DEVFILE (25), to mark if the channel has a sysfs node.
DAHDI_FLAGBIT_DEVFILE is expected to be replaced later on with a proper
pointer to the device (or embedding of the device). I prefer a simple

The default tone lengths are compile time options and they were in
digits.h to make it easy for users to patch. Most of these settings are
potentially overridden from user space via the DAHDI_SET_DIALPARAMS
ioctl currently regardless of these settings.
In r9597 I moved digits.h directly into dahdi-base.c since I thought it
was broken out for sharing between compilation units as opposed to
ease patching.
I also changed the units of the default options to ms instead of in
samples. This way if the sampling frequency changes the user will not
need to update the defaults.

This both removes the need to reference the 'chans'
__dahdi_process_putaudio_chunk and __dahdi_process_getaudio_chunk, and
allows the dahdi_receive / dahdi_transmit logic to be streamlined. DACS
channels can no longer be echocanceled if crossed. However, if a
channel was DACSed with dahi_cfg it couldn't have been echocanceled
anyway since the echo cancelers are disabled on the channel by default.

This change primarily is a memory reduction. Most users only ever have
a single tone zone loaded so we can save some mostly unused pointers by
using a list instead of an array. Since we also have a pointer to the
dahdi_zone in struct dahdi_chan, we also don't need to store the integer
that is an index into that array. This saves 4 bytes for every channel
allocated in the system. Finally, we don't need a separate default_zone
member since we're on a list, we can define the first element on
the list to always be the default zone.
Additionally, all reference counted structures in the drivers should
standardize on kref as much as possible for simplicity.

Some spans, specifically dynamic local spans, should never be the timing
master since they are dependent on some other timing source driving
them.
The bit in 'struct dahdi_span' is named cannot provide timing so that by
default the other drivers will set it to 0.
This is loosely related to issue #13205 but doesn't address any of the
other elements of that issue about how to allow the user to configure
what the master span order of succession is.

Move the try_module_get/module_put calls from the various dynamic
drivers into the "core" dahdi_dynamic.c file itself. This way, a
reference count can always be held while calling through the function
pointers. This is enabled by adding an .owner field to 'struct
dahdi_dynamic_driver'.
Dynamic spans are also unique in dahdi in that they require a "dahdi_cfg
-s" to stop them and release the references on the modules. This is
counterintuitive. This change makes sure they are reference counted just
like other spans and on driver unload, if there aren't any open handles
from userspace, they will take care of unwinding themselves.

Using semaphores as mutexes was removed from the kernel in 4882720b267b.
Just use straight semaphores now. 'DECLARE_MUTEX()' -> 'DEFINE_SEMAPHORE()'
and 'init_MUTEX()' -> 'sema_init()'.

Conference links do not appear to be in use anymore and they are now
removed. I could not find any references to this ioctl in the asterisk
repository, or zaptel user space tools.

DAHDI does not support any kernels older than 2.6.9. No need
to keep the old HDLC interface support around.

Push all tests for the DAHDI_FLAGBIT_NETDEV flag behind a
'dahdi_have_netdev' function so if CONFIG_DAHDI_NET is not defined the
compiler can just remove all the flag tests. Also, makes sure that the
bit is checked / set atomically.

Add optional interface to allow software echo cans to process the
transmitted samples. Can be used for things like DC removal.
I used the following patches uploaded by biohumanoid but changed the
name of 'echocan_hpf_tx' to 'echoan_process_tx and put the changes
behind a compile time option.

The check for DEFINE_SPINLOCK was spread throughout the source tree. If
not defined we can just define it in inlucde/dahdi/kernel.h. Now
include/dahdi/kernel.h is the only place that references
SPIN_LOCK_UNLOCKED (which breaks lockdep checking if DEFINE_SPINLOCK is
otherwise defined in the kernel).

When no hardware spans are configured DAHDI will use a kernel timer in order
provide timing for conferences. This is what dahdi_dummy historically was used
for. When kernel timers are used to provide timing DAHDI can both potentially
slow the rate at which time timer runs and also needs to account for how many
milliseconds of audio are processed for each 'tick' of process_masterspan.
The result is that if you are only using DAHDI for app_meetme, you can change
DAHDI_CHUNKSIZE to 40 (5ms) or 80 (10ms) bytes to reduce overhead since user
space is dealing with chunks of 20ms by default anyway.
NOTE: If you set this, you may still need to comment out the board drivers in
drivers/dahdi/Kbuild since they all do not support operating with a
DAHDI_CHUNKSIZE != 8 currently.

Before CONFIG_DAHDI_PPP can be on by default, some more work needs to be
done to ensure that the ppp_generic module is not always loaded and
that all channels do not carry around all the PPP members unnecessarily.

When compiling dahdi-linux I expect ppp support to be compiled in even if the
kernel config has PPP configured as a module.

This needs some more testing before it's on by default. If the card is
otherwise functioning, these messages may be confusing to the user. If
the card is not functioning, the driver can be reloaded with debug to
check for this condition.
