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

2011-01-18dahdi: Fix recent regression with native bridging.Shaun Ruffell
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.

2011-01-17dahdi: Permit open pseudo channels before spans are registered.Shaun Ruffell
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.

* Separate out device generation in dahdi_[un]register to separate functions. * As we don't keep anywhere the information of whether or not * there's 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 flag for now as it does not break ABI.

2011-01-05dahdi: Ensure we have room to keep all span channels contiguous.Shaun Ruffell
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.

2011-01-05dahdi: Move the default tone lengths into include/dahdi/dahdi_config.hShaun Ruffell
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.

2011-01-03dahdi: Do not locate new master in interrupt context.Shaun Ruffell
When a span goes into alarm it will look for a potential new master span. For dynamic spans that are running their processing in the sync_tick callback, the chan_lock will already be held.

2011-01-03dahdi: Add module parameter to limit number of pseudo channels.Shaun Ruffell
Since there isn't a fixed array to hold all the channels, and also limit the total number of channels that can be created, we'll add a module parameter to allow the system administrator to specify the maximum number of pseudo channels. This is to prevent a potentially non-privledged process from consuming too much CPU (since all pseudos 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: ]# echo <new limit> > /sys/module/dahdi/parameters/max_psuedo_channels Signed-off-by: Shaun Ruffell <sruffell@digium.com> Acked-by: Kinsey Moore <kmoore@digium.com> git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@9610 a0bf4364-ded3-4de4-8d8a-66a801d63aff

In dahdi_chec_conf, dahdi_chan_unreg, and dahdi_ioctl_confdiag maxchans and DAHDI_MAX_CHANNELS was used to scan through all the channels. Since the channels are stored on the list of spans and list of pseudo channels, we can directly iterate through those lists.

2011-01-03dahdi: Drop 'chans' reference in chan_from_num.Shaun Ruffell
Part of getting rid of global chans array. We need to search the list of spans and the list of pseudo channels.

2011-01-03dahdi: When DACS is enabled, hold a pointer directly to the crossed channel.Shaun Ruffell
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.

2011-01-03dahdi: Change reference counting for tone zones.Shaun Ruffell
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.

kasprintf will be used in upcoming changes and it's not supported on RHEL4 kernels. This change essentially backports it.
