2010-09-20dahdi: Issue warning if DAHDI_INDIRECT ioctl is used.Shaun Ruffell
DAHDI_INDIRECT is only used when setting up pciradio channels. dahdi_cfg no longer should need DAHDI_INDIRECT since revision 9352.

2010-09-20dahdi: Use 'chan' convenience pointer in dahdi_receive.Shaun Ruffell
Simplifies the function and may increase performance due to decreased dereferencing of the span and channel array.

2010-09-20dahdi: Use 'chan' convenience pointer in dahdi_transmit.Shaun Ruffell
I believe this makes it a little more clear what is happening. Also could provide a potential speedup if the span doesn't need to be constantly dereferenced (although an optimizer might make this moot). Regardless, this change doesn't hurt.

2010-09-20dahdi: chans[ms->confna] -> conf_chan.Shaun Ruffell
In __dahdi_process_getaudio_chunk and __dahdi_process_putaudio_chunk we can streamline the operation slightly by saving a constant pointer to the conference channel instead of constantly dereferencing the master channel and indexing into the chan array.

2010-09-20dahdi: Refactor some of the access to the 'spans' array.Shaun Ruffell

2010-09-20dahdi: Be more tolerant of surprise removal of channels.Shaun Ruffell
Enable DAHDI to detect if an operation on a file handle refers to a channel that may have been unregistered. This can occur, for example, when a board driver is hot-swapped out in a live system. This patch ensures that file->private_data is always properly set for any open channel, and it's set back to NULL when a channel is unregistered. This way file->private_data can be used to check whether it's valid to perform an operation on the channel. (NOTE: There is still a race condition here if the driver was unbound on one processor during the window of time between when file->private_data was checked and the system call finishes). Also, since DAHDI should only return -ENODEV on read or write when there was a surprise device removal on a running system this sleep can prevent the system from becoming unresponsive if the userspace application does not check for the -ENODEV error and constantly tries to call read with elevated privileges.

2010-09-14dahdi: Remove unused functions __buf_munge and __buf_cpush.Shaun Ruffell
These functions were only defined if BUF_MUNGE was defined, but even if that symbol is defined there is not anyplace in the driver where these functions were then called. This has been in the code since rev 87 so this is most likely stale debugging code. Feel free to revert if this is actually used somewhere that is not apparent.

2010-09-08wct4xxp: Update span-local struct with timing infoRuss Meyerriecks
dahdi_tool was incorrectly reporting all spans to be in local timing mode. This is because the driver tracks which span it's timing syncs to, within the card local struct "wc".

Older kernels do not like the 'bool' type and I cannot just add it into include/dahdi/kernel.h without compile messages in the xpp driver where bool is defined directly.

2010-08-17wcte12xp, wctdm24xxp: Add compile time option CONFIG_VOICEBUS_ECREFERENCE.Shaun Ruffell
Add compile time option to improve the reference signal provided to software echo cancelers. The intent here is for this functionality to become the default behavior but more testing and work on the edge cases is needed. It's being brought in now as a compile time option since there have been reports that it helps in some environments. Instead of using two buffers, which means that at best we're two milliseconds behind, use a circular buffer where audio data is written on the transmit side and read on the receive path. In this way high latency values will not interfere with the operation of software echo cancelers. DAHDI-291. DAHDI-387.
