1c42df4cd1 core timer: don't hang when the clock goes back.
If the clock shifts back, don't hang in a loop of running
process_masterspan from the timer interrupt forever.

Fixes a regression of r9407.

(closes issue #19035)

After talking with Tzafrir on IRC, I combined the check if your far ahead
with the check if you're behind and added a '\n' at the end of the
existing "detected time shift" message.  That is why this patch is
different than what is posted on issue #19035.

d43e2d3ade dahdi: Do not rebuild dahdi-base.c when only updating the version.
This moves the version string into dahdi-version.c that is then linked into
dahdi-base.c and dahdi-sysfs.c.  This speeds builds on slow computers since
dahdi-base.c and dahdi-sysfs.c does not need to be rebuilt if only the version
string is changing.

a340db5e76 wct4xxp: Reduce stack usage in oct612x API.
Reduce the stack usage by replacing the mOCT6100_RETRIEVE_NLP_CONF_DWORD
and mOCT6100_SAVE_NLP_CONF_DWORD macros with functions. Some compilers
do a better job of optimizing the local variables declared in those
macros than others.

c9e258b9b0 wct4xxp: Reduce the memory footprint of the hardware echocanceler.
This saves ~300K of kernel memory for each quad or dual span VPM.  Due
to the fact that this change disables caching of the NLP words (among
other things), the time to disable the echocans appears to have
increased by ~1ms.

4389604ffd dahdi: Analog spans do not have to be marked RUNNING to become master.
Fixes a regression introduced in r9611. Analog spans would never become
the master since the SPANSTART ioctl is not typically called on them,
and therefore they were never marked RUNNING.  The result could be audio
problems.

I'm marking this as related to issue 13205 since it's generally all
related to how should the drivers select which span is the master.  I
also mark as related to issue 16165 because the problems experienced are
a result of the same fundamental issue.

e7d9a67f72 dahdi: Experimentally remove dependency on the Big Kernel Lock.
With the release of Linux 2.6.37, the Big Kernel Lock is now a compile
time option.  This change adds a mutex around the one place in the code
that we already knew was dependent on the lock_kernel/unlock_kernel
calls for serialization and drops the other calls to
lock_kernel/unlock_kernel if CONFIG_BKL is not defined.

This is *mostly* the dahdi-no-bkl.patch with a few minor whitespace
changes, the global_dialparmslock made static, and a warning added to
let people know they are running an experimental configuration.

Eliminates the interruptible_sleep_on deprecated and prevents the driver from
triggering the SLEEP_ON_BKLCHECK warning.

It is still desirable to convert the cmdq to something more like what is in
the single span to eliminate the need to schedule the sleeping process every
millisecond while we're waiting for the command to complete.

f2b7303161 dahdi: Fix recent regression with native bridging.
This fixes a regression introduced in r9603.  That commit removed
DAHDI_CONF_DIGITALMON handling (which is used to natively bridge two
channels that cannot be crossed in the board driver / hardware) since I
mistakenly thought that it was only part of the DACS handling.  The
symptom of the regression is muted audio when Asterisk tries to natively
bridge two channels.

4fea8415d6 dahdi: Permit open pseudo channels before spans are registered.
Move pseudo channel numbers up into a high range so that their presence
does not interfere with assigning channel numbers for the channels
implemented on spans. Otherwise, if a pseudo channel was opened up
before an expected span was registered, all the channel numbers in the
newly registered span would be bumped up one. This does limit the number
of real channels that a single system may have registered to 32K (but in
dahdi-linux 2.4.0 and below you were limited to 1024 channels anyway,
both real and pseudo).

Also, the string name of the Pseudo channel is now based off the
number of Pseudo channels and not the total number of channels.

68c0c37691 dahdi: Ensure we have room to keep all span channels contiguous.
This fixes a regression from r9609 that Tzafrir reported.  If you
register multiple spans, then remove the first span and try to register
a new span with more channels then the old span, you could end up with
multiple channels with the same number.

This change ensures that spans are ordered and that channels on a span
are always contiguous and ordered in relation to the spans.

In previous released versions of DAHDI (2.4.0 and below) this condition
would result in spans that may not have contiguous blocks of channels.
So it fixes both a recent regression and improves the behavior.

ease patching.

parameter to allow the system administrator to specify the maximum

are checked each "tick" for conferencing) and kernel memory.

By default the number of pseudo channels is limited to 512.  Change the
default limit with:

]# modprobe dahdi max_pseudo_channels=<new limit>

or at runtime with:

daf96e677d dahdi: Change reference counting for tone zones.
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.

rwlocks are slowly being deprecated because they typically do not

fdaa2d3f49 dahdi: Take a reference count on module when operating on spans directly.
Normally, spans are accessed via channels, which increment the reference
count on the supporting module as part of the open call.  When operating
on spans by number we are susceptible to a module_unload while we are
accessing the span.

Renames find_span to span_find_and_get to indicate that we're both
finding the span by number and increasing the reference count on the
span.  Spans themselves don't currently have reference counts, but we
can increment the reference count on the module that owns the spans.
This will prevent the module that has the span from unloading in the
middle of a span_config call, which in the case of the wcte12xp can take
awhile since the VPM firmware is loading.

Hopefully in the near future the spans themselves will be reference
counted directly.

c050ca9065 dahdi: Allow spans to advertise if they can provide any timing.
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.

e3bf2fe45d dahdi_dynamic: Use dahdi_span_ops.sync_tick for driving dynamic spans.
Dynamic spans that are unable to provide their own timing, like dahdi
local spans, typically derived their timing source from
dahdi_dynamic_ioctl(0,0) call in process_masterspan.

This change uses the sync_tick member of dahdi_span_ops instead so that
dynamic operations do not happen on a span until it is fully registered.
Also removes the check for dahdi_dynamic_ioctl in process masterspan for
those users that never load a dynamic span.

8212485969 dahdi_dynamic: dynamic drivers should not reference count themselves.
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.

a35b0b21da wcb4xxp: HDLC packets do not pass over D-channel.
dahdi/wcb4xxp driver used with Digium Wildcard B410 quad-BRI PCI card
unable to communicate with another ISDN device (ISDN phone, another port
of B410). It appears that B-channels are capable to transport data, but
D-channel is not.

Debug output added into the driver shows that packets are transmitted to
the D-channel, but no packets are received. Further investigation shows
that no interrupts received from Rx FIFO associated with D-channel,
although packets are delivered to the FIFO. I've found that problem is
in improper usage of chan->chanpos while indexing the fifo index
(bspan->fifos): chanpos starts from 1 and fifos starts from 0.
Therefore, garbage read instead of fifo number.

4de462c3e0 wctdm24xxp, wcte12xp: Disable PCI read-line multiple command.
There are some platforms where the read-line multiple transaction causes
packets to be dropped in the voicebus pipeline.  The only observable
behavior is that packets just go "missing" in the pipeline.  This also
only appears to affect PCI cards.

A typical 'symptom' of this problem is you may see IRQ misses increasing
without any corresponding "bumps" in latency in the kernel message log.
Normally, IRQ misses are correlated to latency bumps since that is an
indication that the host was not able to service the card interrupt in a
timely fashion. DAHDI-510 DAHDI-774

Changed the echocan factory name to a function (get_name) called to get the

Most of this time is spent sleeping waiting for reads from the framer to

For example, the following command will load and configure the driver and
then print the load average every 10 seconds.

/proc/loadavg; sleep 10; let x=$x-1; done
