2011-01-03'dahdi_copy_string()' -> 'strlcpy()'Shaun Ruffell
There is already a safe string copying function in all the kernels DAHDI currently supports. 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@9585 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2010-09-24Move test for DEFINE_SPINLOCK into include/dahdi/kernel.hShaun Ruffell
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).

2009-03-11Keep transcoders on a list in registration order.Shaun Ruffell
This fixes a bug where it was possible for there to be a transcoder in position "1" but not in position "0" if a transcoder hardware driver was loaded, unloaded, and reloaded again without also reloading dahdi_transcode. The result is that codec_dahdi fails to enumerate all the transcoders in the system. (closes issue #14627) Reported by: xblurone git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6114 a0bf4364-ded3-4de4-8d8a-66a801d63aff

keep the check in there to avoid problems in the future (and since this code path is only used when opening a new transcoder session) I made the check conditional on running an SMP kernel. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@5635 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2008-12-04Do not use an already built channel if the source and destination formats doShaun Ruffell
not match the formats we want. This fixes a regression introduced by the new transcoder interface where a translation path from one complex codec to another can result in garbled audio. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@5433 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2008-10-10- Ensure that the source format is considered when selecting a transcoder.Shaun Ruffell
- When a command is to be retried, turn off the TX_COMPLETE flag before resubmitting it to the hardware. This should elimate some of the warnings printed to the kernel log in the wctc4xxp_transmit_cmd function. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@5084 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2008-08-19Couple of fixes for the transcoder:Shaun Ruffell
- In dahdi_transcode.c, Embed the identifiation number, assigned sequentially when the transcoders are registered, in the transcoder structure. This allows DAHDI_TC_GETINFO to work as expected even though the transcoders are rotated on the list in order to spread the load. - In wctc4xxp, fix bug where all transcoders are named tc400b0. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@4791 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2008-08-06A significant change to the DAHDI transcoder interface and the wctc4xxpShaun Ruffell
driver which breaks backwards compatibility. Basically, I've replaced the memory mapped interface with a read/write interface that allows codec_dahdi to communicate with the hardware transcoder the exact size of the packet to be transcoded. This eliminates issues with remote devices that send G729.B CNG packets even though asterisk does not support them. From a user standpoint: - The transcoder drivers are much more robust in light of system / external conditions. From a developer standpoint: - DAHDI_TRANSCODE_OP is no longer supported, instead use DAHDI_TC_ALLOCATE, DAHDI_TC_GETINFO, and write/read. - Memory and stack usage is reduced (stack usage could still be reduced some more by continuing the process of getting rid of the users of wctc4xxp_send_cmd and wctc4xxp_create_cmd). - If more than one card is in the system channels will be allocated in a round-robin fashion from all available cards, reducing contention for the supervisor channel. - There is no longer a tc400b workqueue created that will not show up in the process list. - Commands and their responses are now explicitly matched up which elimated certain errors caused by unsolicited messages from the transcoder confusing the driver. - There is now an option to export a network interface for capturing traffic to/from the hardware transcoder. - codec_test has been removed from the dadhi/linux package. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@4717 a0bf4364-ded3-4de4-8d8a-66a801d63aff
