cb4e4d0068 dahdi: sysfs: use dynamically allocated chrdev's
* Channels have their own dynamically allocated major number
* No arbitrary limit of minor < 250 (no collision with /dev/timer, etc)
* We still have arbitrary limit of channo < DAHDI_MAX_CHANNELS
  (should be raised?)
* FIXME: need to check to FIXME's

5f7ebe98da dahdi: Only watch transitions of ABIT when using E&M signalling.
This resolves an issue with a Glenayre GL3000 Paging Terminal with v8.000
software. The Glenayre would change both A and B bits to signal on/off hook
states, but there were a couple of milliseconds between when those bits changed.
This resulted in DAHDI generating an on-hook event to Asterisk before generating
the off-hook event and therefore Asterisk terminated the call prematurely.

Looking the A and B bits before this patch:

Asterisk (AB)   Glenayre (AB)
00              00                 Both sides on-hook
11              00                 Asterisk goes off hook to sieze line.
11              01                 Glenayre starts going-offhook. On-hook event
                                     sent to Asterisk from drivers since bits
                                     changed but ABIT was still 0.
11              11                 Glenayre finishes going off-hook. Off-hook
                                     event sent to Asterisk since ABIT changed
                                     from 0 to 1.
00              11                 Asterisk, processes on-hook event and goes
                                     on-hook itself to release line.
00              00                 Glenayre releases line. Call fails.

After this patch:

Asterisk (AB)   Glenayre (AB)
00              00                 Both sides on-hook
11              00                 Asterisk initiates call
11              01                 Glenayre starts handling call. No event is
                                     sent to Asterisk since only ABIT is checked.
11              11                 Glanayre finishes going off-hook. Call
                                     proceeds normally.

da8b96d725 dahdi: Remove unused 'rxbufpolicy' and 'rxdisable' from dahdi_chan.
Since r5021 [1], first released in DAHDI-Linux 2.2.0, it's been impossible for
user space to change the rxbufpolicy. This hasn't caused any problems and it's
safe to remove a few more of the vestiges of the rxbufpolicy from the driver.

This streamlines the code path in a few places and saves 8 bytes from the size
of struct dahdi_chan.

The user visible parts are maintained and will indicate
DAHDI_POLICY_IMMEDIATE, like it has since 2.2.0.

d349fe62fe wctdm24xxp: Set dahdi_span.spantype to SPANTYPE_ANALOG_MIXED.
Since r10683 "convert span->spantype to enumerated type" [1] the spantype was
changed from a string provided by the board drivers to an enumerated type that
is handled by the core of DAHDI. This was done to simplify the task of
dahdi_genconf since there is only one place to look for the valid strings that
can be exported in sysfs.

This eliminates the following warning on driver load:
  Warning: Span %s didn't specify a spantype. Please fix driver!

25ce85e770 dahdi: Filter 'HWEC' from DAHDI_GETVERSION results if hwec is really not present.
Internally in DAHDI there is always a hardware echocan factory registered and
available. Having this factory always registered allows for DAHDI to work in a
backward compatible fashion. Namely, by default DAHDI will always use a hardware
echocan if one is available unless 'hwec_overrides_swec' dahdi module parameter
is set to 0 on load. However, if there were no real hardware echocans available
in the system dahdi would still report "Echo Canceller(s): HWEC" in the
dahdi_cfg -v output since the hwec factory is always there.

After this change dahdi_cfg will no longer report HWEC as one of the available
echocans if there isn't a physical span present that actually has a hardware
echocan.

84e70cdac5 wctdm24xxp: Only two polarity reversals are needed to validate RING on FXO ports.
This fixes a regression introduced in commit r10186 "wctdm24xxp: Use time
interval for debouncing FXO ring detect." [1] which was first released in
DAHDI-Linux 2.6.0. This only affects users with analog trunks whose providers do
not present 4 polarity reversals on the ring signals. The reporter of this issue
is based in South Africa.

[1] http://svnview.digium.com/svn/dahdi?view=revision&revision=10168

In prior versions, the ring detector did not check for polarity reversals, only
the presence of ringing voltage unless fwringdetect or neonmwi_monitor mode was
set, and even when one of those modes were set, the driver only needed two
reversals to validate a ring. This commit allows the driver to always stay in
fwringdetect mode but restores the requirement for only two reversals.

Also included in this commit is a change to ensure that ringing is not reported
when debouncing lost battery which can happen when voltage is swinging through
0.

7e614f4d29 wcte12xp: Fix stack corruption when checking T1 RBS states.
This fixes an (embarrassing) error in t1_check_sigbits in the previous commit
where I was writing pass the end of an array on the stack.

Now instead of using an array on the stack, of which all elements were not used,
the pending commands are now stored on a list. I also removed the automatic free
of commands from __t1_getresults and now the function that allocated the command
now frees them.

I believe this will be less error-prone going forward.

24ed250673 wcte12xp: Fix pulse digit detection when set for FXO signalling modes.
The frequency that the RBS registers were polled was too slow to catch the pulse
dialing digits. The result was that often times dahdi would generate WINK events
instead of PULSEDIGIT events.

This speeds up the rate at which the registers are checked from 100ms to 33ms
and also makes the process of checking the registers quicker by queing up all
the reads at once.

d6c9c4c9da wcb4xxp: Support for when network side deactivates layer1.
This is a port of the functionality in the wctdm24xxp driver to support power
savings modes. Specifically, if the the network side of a BRI spans deactivates
the span to save power, the B410P  previously automatically activated it again.
Now, if persistentlayer1=0 module parameter is set, the span will be allowed to
stay deactivated until layer two has a message to send on the dchannel.

This patch does not change any of the default behavior of the B410P driver and
the defaults for the persistentlayer1 option is inconsistent with that of the
B400M modules in the wctdm24xxp driver.

rev. 10502 of the FPGA firmware for the new E-Main rev. 4 fixes a potential
issue when used on Xorcom XR1000 systems: an issue with the power supply may
cause the unit to reset.

Note that there is no issue with previous models, with a normal setup of an
Astribank, or other XRx000 systems.

3d52bdd52f dahdi_dummy: Include timer.h instead of time.h
It appears that some kernel configurations do not include timer.h in any of
the include files that are included by dahdi_dummy. The timer_structs are
defined in timer.h and not time.h, so this change is correct even though I
never could find a configuation myself that actually failed to compile.

This has negligible impact since dahdi_dummy is not compiled by default.

034818dd81 dahdi_dynamic_eth: Make ztdeth_exit() symetrical with ztdeth_init() and fix race on unload.
Minor change to follow generally recommended practice. Prevents new packets
from being queued up for devices when they are about to be cleaned up. Also
clean up any skbs that may still be on the queue after unloading.

Also closes anoter potential kernel oops on module unload. It was possible to
delete the private structure while the master span process was running. The
result was an attempt to page memory from interrupt context.

Make sure that the pvt function is set and cleared under the zlock. Also do
not assume that the pvt pointer is valid in ztdeth_transmit.

I saw a kernel oops that was the result of the timer running after the

d46ad9bca1 dahdi_dynamic: Remove calls to __module_get().
The board drivers are the ones calling the unregister function, and
therefore we do not need to worry about them unloading while calling the
destroy callback.

When destroying spans with the ioctl, replace __module_get() with
try_module_get. This avoids hitting a BUG in module_get on kernel versions <
2.6.29.

ALSO move the call to try_module_get out of the dahdi_dynamic_release function
and into destroy. This way if the destroy callback isn't called because the
dynamic driver is unloading the dynamic device can be left on the list to be
cleaned up by the dahdi_dynamic_unregister_driver function().

4ee22f19d1 dahdi_dynamic: Do not call into dahdi_dynamic without holding reference.
Instead of registering a function pointer, register a dahdi_dynamic_ops
structure that contains the owner as well as the ioctl callback. This way
dahdi.ko can bump up the reference count on dahdi_dynamic.ko before calling
the ioctl callback.

Also, use the registration mutex to guard against the module being unloaded
between the time the structure pointer was checked, and the module reference
is taken.

The driver makes the assumption that interrupts are disabled but this cannot

the interrupt handler is running.

This eliminates the "IRQF_DISABLED is not guaranteed on shared IRQs" warning

59caf11dbe xpp: FXS: added a 'lower_ringing_noise' parameter
* Adds a new parameter, 'lower_ringing_noise', to module xpd_fxs.

* Makes the "power-down" behaviour that was added
  in upstream svn r10478, switchable in runtime.

* By default (false), makes the vbat_h behave like it did
  before the power-down change.
  - I.e: vbat_h is held throughout the ringing period (during
    both ring-up/ring-down)
  - So this patch revert part of r10478

* When switched to true, activate the "power-down" behaviour.
  - I.e: vbat_h follows the ring-up/ring-down.
  - This behaviour lowers the noise caused by group ringing of
    FXS channels in the same unit, but causes problems with CallerID.
