	* q931.c: Lucent switch implementation bug workaround (Part 2)

	  Work around a bug in a Lucent switch implementation that sets the
	  extension bit in octet 3 even though octet 3a is present.

	  The same issue was seen in a NI2 switch implementation.  It was probably a
	  Lucent switch configured for NI2 operation.  To avoid further surprises,
	  I'm going to enable the work around for all North American switch types.

	* q931.c: Lucent switch implementation bug workaround.

	  A bug in a Lucent switch implementation sets the Connected Number
	  information element octet 3 extension bit.  When set that means octet 3 is
	  complete and thus there is no optional octet 3a.  However, the buggy
	  switch still sends octet 3a.  The unexpected octet 3a is interpreted as
	  the first octet 4 and thus the first character in the connected line
	  number is a garbage character.

	  * Work around the switch bug by checking octet 3 and the potential octet
	  3a extension bits.  If they are both set then assume that octet 3a is
	  actually present for the buggy switch types.

	* q931.c: Fix DISCONNECT Progress Indicator ie handling.

	  There are two scenarios that are exposed by DISCONNECT not initializing
	  the progress indicator value before processing the message when the
	  chan_dahdi.conf inbanddisconnect=yes option is set.

	  1) If a DISCONNECT comes in without a Progress Indicator ie and an earlier
	  message (such as SETUP-ACKNOWLEDGE or PROCEEDING) came in with the
	  indicator #8 (Inband audio present) then the DISCONNECT would not cause an
	  immediate hangup.  We would be letting the user hear the inband audio even
	  though there isn't any.

	  calls fail when using Asterisk 1.8 with HA8, HB8, and B410P

	  lines when the line is idle. When layer 1 goes down Asterisk
	  cannot make outgoing calls and the HA8 and HB8 cards also get IRQ
	  misses. The inability to make outgoing calls is because the line
	  is in red alarm and Asterisk will not make calls over a line it
	  considers unavailable. The IRQ misses for the HA8 and HB8 card
	  are because the hardware is switching clock sources from the line
	  which just brought layer 1 down to internal timing. There is a
	  DAHDI option for the B410P card to not tell Asterisk that layer 1
	  went down so Asterisk will allow outgoing calls: "modprobe
	  wcb4xxp teignored=1". There is a similar DAHDI option for the HA8
	  and HB8 cards: "modprobe wctdm24xxp bri_teignored=1".

	  34 - Circuit/channel congestion)). It seems that receiving a
	  RELEASE_COMPLETE in that state blocks one B channel permanently
	  when the call is cancelled by the caller. Background: The ISDN
	  phones (Siemens Gigaset 3035 or CX253) we use for testing
	  additionally contain a DECT base station, which operates as a
	  different endpoint on the ISDN Bus (TEI). If the DECT base
	  station is not in use then there are no DECT phones registered to
	  the base station. The DECT base station responds to an incoming
	  call not directed toward it with (RELEASE_COMPLETE, cause: no
	  user responding). * Made initiate_hangup_if_needed() also hangup
	  the subcall if it is in the NULL state. * Simplified

	* pri_internal.h, prisched.c: Crash if NFAS swaps D channels on a
	  call with an active timer. If a Q.931 call record related timer
	  is started on one NFAS D channel expires after NFAS swaps to
	  another D channel, then libpri could crash. For example: 1)
	  Hangup a call. 1a) Send a DISCONNECT. 1b) Start the T305
	  retransmit timer on the current D channel. 2) The RELEASE comes
	  in on another D channel. 2a) The found call record switches its
	  assignment to the new D channel. 2b) Attempt to stop T305.
	  Unfortunately, the timer was started on another D channel so the
	  attempt does not find the timer to stop. 3) The hangup sequence
	  continues normally and the call record is freed since there is
	  only one call record pool. 4) T305 expires on the original D
	  channel and crashes the system when it uses the stale call record
	  pointer it has saved. Made each D channel timer pool have a
	  unique range of valid timer identifiers. If a given timer
	  identifier is not in the range for the current NFAS D channel,
	  then search the D channel group for the original D channel. JIRA

	* q921.c, q931.c: Made Q.921 delay events to Q.931 if the event
	  could immediately generate response frames. Q.921 was passing a
	  q931_dl_indication(up) event to Q.931 before it was finished

	  only when debugging enabled.

	* q921.c, q931.c: Q.921/Q.931 message debug output improvements.
	  The Q.931 message decode debug output now will follow the correct
	  Q.921 header decode if Q.921 message dumping is enabled. Also the
	  Q.931 message decode will happen when the message actually goes
	  out on the line instead of when Q.931 passes the message to
	  Q.921. Q.921 may have to request a TEI, bring the connection up,
	  or retransmit previous frames before it can actually send the new
	  message.

	* q921.c: Q.921 improvements from comparing Q.921 SDL diagrams with
	  implementation. * Handle sending and receiving DM response frames
	  as needed. * Added handling of received FRMR frames. * Completed
	  implementation of Q921_AWAITING_RELEASE state. (State is
	  currently unreachable since we have no API to initiate sending
	  the DISC message.) * Better NT PTMP TEI allocation. * Reduced
	  more ERROR level severity messages so users will stop panicking
	  when they see ERROR. This is especially true for the Q.921
	  MDL-ERROR messages. * Added better Q.921 visibility when normal
	  debug message level is enabled.

	* q921.c: ISDN BRI does not recover from line faults Q.921 was
	  getting stuck in state 2 (Q921_ASSIGN_AWAITING_TEI). For some
	  reason the network was removing the TEI. Libpri then immediately
	  tried to get a new TEI assigned. The network did not reply to the
	  N202(3) attempts to get a new TEI. Libpri then just gave up
	  trying but did not leave the state. Some paths in Q.921 Figure
	  B.3 were not implemented. Q.921 now transitions to the
	  Q921_TEI_UNASSIGNED state when the N202 count is exceeded. Q.921
	  will wait there until an incoming or outgoing call is attempted.
	  * Fixed initializing the n202_counter. Not initializing the
	  n202_counter would cause the Q921_TEI_IDENTITY_REQUEST to
	  unexpectedly not go out and due to how state transitions were
	  done, Q.921 would get stuck in the Q921_ASSIGN_AWAITING_TEI
	  state. * Fixed start T202 timer fail causing Q.921 to get stuck
	  in the Q921_ASSIGN_AWAITING_TEI state if the network did not
	  respond to the request. * Fixed handling of
	  Q921_TEI_IDENTITY_REMOVE to do the MDL-REMOVE primitive
	  (q921_mdl_remove()) instead of transitioning directly to the
	  Q921_TEI_UNASSIGNED state. Necessary state clean-up was not
	  getting done. * Minor tweaks to q921_mdl_remove(). The worst
	  problem was erroneously generating an error message. * Fixed
	  potential for sending I-frames with an invalid TEI. The I-frame
	  could have been queued when Q.921 did not have an assigned TEI. *
	  Fixed testing of the q931_receive() return value when a UI-frame
	  is received. (closes issue #17570) Reported by: jcovert Patches:

	* q931.c: No audio on inbound J1 calls. Incoming calls specifying
	  the channel using a slot map could not negotiate a B channel
	  correctly. Libpri historically has handled this as an any channel
	  request. However, when chan_dahdi picked a new channel, libpri
	  sent out the recorded slot map and not the new channel selected.
	  Thus the two endpoints would be attached to different B channels
	  and the parties would not hear anything or would hear the wrong
	  parties. This patch restores the historical preference of sending
	  out the channel id using the channel number method if a channel
	  number is available. JIRA LIBPRI-35 Patches:

	* q921.c, q931.c: Improved Q.921/Q.931 debug output. * Debug output
	  for a sent Q.931 message in TE PTMP now uses the best available
	  TEI number instead of always using 127. It could still be wrong
	  if layer 2 does not have a TEI assigned. * Q.921 debug output is
	  grouped better so a decoded message is not split by a blank line.
	  * The Q.921 state is also decoded to a name.

	* q921.c: Q921_TIMER_RECOVERY SDL issue in q921_rnr_rx() Added

	* pri.c, libpri.h: Add pri_new_bri_cb() API - Create BRI D-channel

	  receive handler for that ie. Since connected line (COLP)
	  functionality has been added and this is just an alternate for
	  the Connected Number ie (0x4C), the handler was already written.

	* pri_internal.h, pri_q931.h, q931.c, pridump.c: PTMP NT mode call

	* pri.c, pri_internal.h: Fix debug output so built up output lines

	  debugging. Unfortunately, any pri_message() output that is not a
	  complete line is messed up. The pri_message() function now will
	  accumulate line output until a '\n' is seen on the end.

	* pri_internal.h, q931.c, pri_facility.c: Delay processing of
	  facility ie's after all other ie's are processed. * Some ROSE
	  message processing depends on the presence of other ies. The
	  DivertingLegInformation1, and 3 messages will be used as the
	  default connected line number if the connected number ie is not
	  present. The redirecting number ie is used as a default to the
	  redirecting number in the DivertingLegInformation2 message if the
	  ROSE message does not contain it and the redirecting number ie is
	  present. * Some ROSE message processing depends upon other ie
	  values. The StatusRequest, CCBS-T-Call, and CcRingout messages
	  collectively need the BC, HLC, LLC, called number, called
	  subaddress, calling number, and calling subaddress ie information
	  to be available.

	* pri.c, pri_internal.h, q931.c, pri_facility.c, pri_facility.h,
	  libpri.h: Reimplement callback mechanism to handle APDU response
	  messages that we care about. 1) No sent messages will remain in
	  the APDU queue unless they have an active timer to remove them.
	  The dummy call reference call and global call reference call
	  structures will not act like a memory leak to sent messages. 2)
	  The new T-RESPONSE timer will be the generic response guard if
	  the standards do not otherwise specify a timer for a message
	  response. 3) The callback will be called. If it is called because
	  of a response message, then the callback has an opportunity to
	  indicate if more responses are expected.

	* libpri.h: We now have 32 timers. No need to reserve minimum space

	* pri_internal.h, q931.c, pri_facility.c, pri_facility.h: The
	  facility ie queue needs to remove facilities that have been sent.
	  The facility ie queue needs to remove facilities that have been
	  sent. Otherwise, the queue just grows until the call is
	  terminated. AOC messages can clog the queue during a long call
	  and the dummy call reference may never be deleted. Also removed
	  unneeded elements of struct apdu_event. The callback function was
	  not a good idea since many facility messages do not have
	  responses and the callback would prevents removal of events from
	  the list.

	  a FACILITY message from a phone on the dummy call reference.
	  LibPRI behaved as if the dummy call reference were an invalid
	  call reference and proceeded to respond on the global call

	* pri_q931.h, q931.c: Add SERVICE message support for the
	  'national' switchtype This set of changes integrates SERVICE
	  message support for the 'national' switchtype. The 'national'
	  switchtype uses the 0x43 protocol discriminator. The 'national'
	  SERVICE/SERVICE ACKNOWLEDGE and AT&T SERVICE/SERVICE ACKNOWLEDGE
	  message values are opposite of each other. This is handled by
	  first determining which protocol discriminator is in use, then
	  responding with the appropriate SERVICE ACKNOWLEDGE value. AT&T

	* q921.c, q931.c: Optimized calls to pri_schedule_del(). There is
	  no need to test if a scheduled event is running before calling
	  pri_schedule_del().

	* prisched.c: Cleaned up scheduled events handling code. * Fixed
	  pri_schedule_event() to return 0 on error instead of -1. Zero is
	  a safer value to return. Users would not think that a timer was
	  scheduled. * Fixed potential for pri_schedule_del() to write out
	  of bounds of pri_sched[]. The out of bounds access could occur
	  when pri_schedule_event() returned -1. * Made use all pri_sched[]
	  entries. pri_sched[0] was previously unused. * Removed some
	  unneeded code and recursion since scheduling only runs on master
	  D channel structures. * Added doxygen comments. * Renamed struct
	  pri *pri variables to struct pri *ctrl in this file.

2009-06-09 19:47 +0000 [r859]  Matthew Fredrickson <creslin@digium.com>

	* q921.c: There are two changes in this commit that are bug fixes
	  for various Q.921 issues found in internal testing. Both were
	  exposed/introduced by the TBR4 compliance patch for bug #12861,
	  in changing how retransmissions and in how the transmission queue
	  was maintained. TX-RX message flow and acknowledgement was
	  severely restricted, since the patch changed the behavior so that
	  pending untransmitted frames would not actually be send until the
	  next RR was received in normal circumstances, or REJ when a
	  reject frame was received. On busy links, this can severly limit
	  the amount of useful traffic that is sent, and can slow down
	  message transmission. Until someone can point out where in Q.921
	  it is mandated for us to wait for RR frames to start sending
	  untransmitted messages, the first change is to allow us to send
	  untransmitted frames when we receive new I frames as well, with
	  updated N(R). The other bug fixed is a situation caused by the
	  restricted traffic flow, if an outside process tries to send an
	  I-frame asynchronous to an RR frame, when the transmit window was
	  previously closed and then opened up but an RR has not been
	  received yet. A bug was found with the integration of the old
	  transmit code with the new reject handling code which caused the
	  new frame to be sent immediately, regardless if there were any
	  pending untransmitted I-frames in the queue to be sent and
	  causing an out of order I-frame to be sent to the other side.
	  This bug is also fixed in this patch.

2009-06-03 22:51 +0000 [r836-848]  Richard Mudgett <rmudgett@digium.com>

	* asn1_primitive.c: Made ASN.1 memory dump also display printable

2009-05-29 15:39 +0000 [r824]  Richard Mudgett <rmudgett@digium.com>

	* q931.c: Renamed local struct pri *pri variables to struct pri
