* libpri 1.4.11 released.
2010-05-19 21:50 +0000 [r1703] Richard Mudgett <rmudgett@digium.com>
* q931.c: T309 should not do anything with the global call
reference call record.
2010-05-19 21:30 +0000 [r1702] Matthew Fredrickson <creslin@digium.com>
* q921.c: It's amazing what a tiny bug in the Q.921 SDL diagram can
do to cause trouble.... Fix issue where V_R was not reset and N_R
was consequentially transmitted incorrectly. Particularly in
layer 2 initiated re-establishments.
2010-05-11 22:14 +0000 [r1688] Richard Mudgett <rmudgett@digium.com>
* pri.c, pri_internal.h, q931.c, libpri.h: Dialing an invalid
extension causes incomplete hangup sequence. Revision -r1489
corrected a deviation from Q.931 Section 5.3.2. However, this
resulted in an unexpected behaviour change to the upper layer
(Asterisk). This change restores the legacy hangup behaviour if
the new API call is not used. Use pri_hangup_fix_enable() to
follow Q.931 Section 5.3.2 call hangup better. (closes issue
#17104) Reported by: shawkris Tested by: rmudgett
2010-04-26 19:54 +0000 [r1664-1675] Richard Mudgett <rmudgett@digium.com>
* q931.c: Simplified some protocol discriminator handling code.
* q931.c: Garbage on the end of Q.931 messages causing calls to
fail to connect. The DAHDI driver had a bug where an extra byte
appeared on the end of Q.931 messages. This garbage byte caused
the message to be discarded with the diagnostic "XXX Message
longer than it should be?? XXX". The Q.931 message will no longer
be discarded if there were earlier ie's in the message. This
patch also addresses the potential problem of reading beyond the
buffer when trying to parse the garbage data. Thanks to roeften
for the base patch. (closes issue #14378) Reported by: timking
* q921.c: Avoid using a cast.
* q931.c: Cleanup some pri debug output line presentation.
2010-04-19 22:40 +0000 [r1625-1630] Richard Mudgett <rmudgett@digium.com>
* pri_internal.h, pri_q931.h, q931.c, pridump.c: PTMP NT mode call
reference value ambiguity. Since the TE side can pick CR values
independently, the TE CR needs to be qualified by TEI to
distinguish CR values from other devices. Without doing this,
multiple phones on the BRI line will have intermittent call
failures. JIRA LIBPRI-30 Also eliminated some wierdness in
q931_status() and several places where it is called.
* q921.c: Fix potential crash when pridump.c calls q921_dump() with
NULL pri ptr.
2010-04-15 18:43 +0000 [r1596] Richard Mudgett <rmudgett@digium.com>
* pri.c, pri_internal.h: Make some internal routines available to
other libpri components.
2010-04-09 21:43 +0000 [r1577] Richard Mudgett <rmudgett@digium.com>
* q931.c: Only one PROCEEDING message per call please.
2010-03-18 15:50 +0000 [r1534-1547] Richard Mudgett <rmudgett@digium.com>
* q931.c: Move a comment closer to where it has relevance.
* pri.c, pri_internal.h, q921.c, q931.c, pri_facility.c:
Miscellaneous simple reorganization. 1) Make PRI_MASTER() no
longer check for a NULL parameter. It is the caller's
responsibility. Not many callers could have passed a NULL without
crashing before or after anyway. 2) Replace calls to
q931_is_ptmp() with PTMP_MODE(). They were equivalent. 3) Made
the following boolean config options bit fields: sendfacility,
overlapdial, chan_mapping_logical, and service_message_support.
2010-03-02 23:47 +0000 [r1511] Richard Mudgett <rmudgett@digium.com>
* pri.c, pri_internal.h, q921.c: Restore ability to change the
Q.921 K value. The Q.921 rewrite only used value of PRI_TIMER_K
right after it was set to the default. The Q.921 window size was
thus no longer alterable by the user. (closes issue #16909)

2010-02-11 21:47 +0000 [r1488-1489] Richard Mudgett <rmudgett@digium.com>
* q931.c: Must send DISCONNECT if we have sent a response to a
SETUP message. Q.931 Section 5.3.2 a) says we send a
RELEASE_COMPLETE to reject a call SETUP if we have not already
sent a message in response to the SETUP message.
* pri.c, libpri.h: Minor comment changes.
2010-02-11 17:35 +0000 [r1482] Wendell Thompson <wthompson@digium.com>
* Makefile: Added CPUARCH option for selecting a 32-bit build from
the command line.
2010-02-08 23:29 +0000 [r1470-1476] Matthew Fredrickson <creslin@digium.com>
* q921.c: Revert useless check of pri->t200_timer value, since
scheduler routines check the value anyways.
* q921.c: Make sure we set the l3initiated flag when PTP links are
attempted to be re-established
2010-02-05 23:34 +0000 [r1464] Richard Mudgett <rmudgett@digium.com>
* pri.c: pri_restart() is no longer needed since the Q.921 rewrite.
Don't output error message for a deprecated function.
2010-01-29 21:55 +0000 [r1457] Matthew Fredrickson <creslin@digium.com>
* q921.c: Sense of statement was inverted from what it should have
been. Might have caused false T200 operation on reception of
I-frames.
2010-01-29 19:32 +0000 [r1451] Richard Mudgett <rmudgett@digium.com>
* q921.c: Only set eres if there actually is an event to pass up.
(issue 16713)
2010-01-29 17:27 +0000 [r1445] Matthew Fredrickson <creslin@digium.com>
* q921.c: Fix bug in which an event was lost if an I-frame was
received during a timer recovery state (related to #16713)
2010-01-26 21:04 +0000 [r1439] Richard Mudgett <rmudgett@digium.com>
* q921.c: Don't be so noisy when D channel is down.
2010-01-19 21:53 +0000 [r1426] Richard Mudgett <rmudgett@digium.com>
* q921.c, q931.c: Fix TE PTMP side sending FACILITY messages on the
dummy call reference. Only the NT PTMP side can send Q.931
broadcast messages. Also removed an inaccurate comment in Q.921
and made q921_mdl_handle_error_callback() call the correct struct
pri free function.
2010-01-15 18:28 +0000 [r1414] Richard Mudgett <rmudgett@digium.com>
* q921.c, q931.c: Make some debugging messages conditional and some
minor reformating changes.
2010-01-13 19:37 +0000 [r1406] Matthew Fredrickson <creslin@digium.com>
* pri.c, pri_internal.h, pri_q921.h, Makefile, pri_q931.h, q921.c,
q931.c: Merge of Q.921 rewrite branch for wider testing.
2009-12-09 20:59 +0000 [r1374] Richard Mudgett <rmudgett@digium.com>
* q931.c: Extracted q931_fill_ring_event() from
post_handle_q931_message(). Done so it is easier to see what was
done in ccbs branch.
2009-11-21 02:40 +0000 [r1345-1351] Richard Mudgett <rmudgett@digium.com>
* pri.c, pri_internal.h: Fix debug output so built up output lines
are readable again. A recent change to Asterisk put the span
number at the begining of each line. This is a good thing if you
need to debug multiple spans or forget which span you are
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.
2009-11-18 00:36 +0000 [r1331] Richard Mudgett <rmudgett@digium.com>
* q931.c: Merged revision 1328 from
https://origsvn.digium.com/svn/libpri/team/mattf/libpri-1.4-q921-rewrite
.......... r1328 | mattf | 2009-11-17 15:16:11 -0600 (Tue, 17 Nov
2009) | 1 line outboundbroadcast isn't set at this time, since it
is set after the message is transmited, so we must use other
criteria to determine the need for broadcast on a setup
..........
2009-11-14 00:20 +0000 [r1310-1322] Richard Mudgett <rmudgett@digium.com>
* 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
anymore.
* pri_internal.h, pri_facility.c: There must be only one source for
the invoke id values per D channel group. If there are
potentially multiple sources for the invoke id sequence then we
could get confused if there are multiple outstanding messages
with the same invoke id that get responses.
2009-11-11 00:22 +0000 [r1291] Matthew Fredrickson <creslin@digium.com>
* pri_internal.h, q921.c: Make sure we also revive links for PRIs,
not just PTMP TE BRIs when we get a disconnect message
2009-11-10 21:51 +0000 [r1283] Richard Mudgett <rmudgett@digium.com>
* 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.
2009-11-10 20:25 +0000 [r1276] Matthew Fredrickson <creslin@digium.com>
* q921.c: Re-add back in support for TE initiated layer 2
activation
2009-11-10 19:27 +0000 [r1268-1275] Richard Mudgett <rmudgett@digium.com>
* pri.c, pri_internal.h, q931.c, libpri.h: Add dummy call reference
support. Fixes problem where PTMP NT mode responds erroneously to
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
reference.
* pri_internal.h: Remove unused callingsubaddr[].
2009-11-03 17:19 +0000 [r1255-1261] Richard Mudgett <rmudgett@digium.com>
* pri_q931.h, q931.c: Unknown IE 50 (cs5, Unknown Information
Element) Add code to recognize the code set 5 ie 50 (calling
party category) to suppress the unknown IE message. (closes issue
#13828) Reported by: fdecher Patches:

* q931.c: NT PTMP did not report busy when calling a busy phone.
The caller would not get a busy indication when calling a busy
phone. Timer T303 is not supposed to be stopped when
RELEASE_COMPLETE received. When T303 expires we will now report
the last clearing cause code to the caller if we received one.
2009-10-23 23:47 +0000 [r1242-1249] Richard Mudgett <rmudgett@digium.com>
* pri_internal.h, pri_facility.c: Add subaddress handling to
existing messages and functions. Connected line updates when
transfering calls does not completely support subaddresses yet.
* pri.c, pri_internal.h, pri_q921.h, pri_q931.h, q921.c, q931.c,
pri_facility.c, pri_facility.h, libpri.h: Add BRI PTMP NT mode,
HOLD/RETRIEVE, Call rerouting/deflection, and keypad facility
support. * Added support for BRI PTMP NT mode. (Overlap dialing
NT -> TE not supported.) * Added handling of received
HOLD/RETRIEVE messages and the optional ability to transfer a
held call on disconnect similar to an analog phone. * Added
CallRerouting/CallDeflection support for Q.SIG, ETSI PTP, ETSI
PTMP. Will reroute/deflect an outgoing call when receive the
message. Can use the DAHDISendCallreroutingFacility to send the
message for the supported switches. * Added ability to
send/receive keypad digits in the SETUP message. Send keypad
digits in SETUP message:
Dial(DAHDI/g1[/K<keypad_digits>][/extension]) Access any received
keypad digits in SETUP message by: ${CHANNEL(keypad_digits)}

2009-10-22 16:16 +0000 [r1230] Richard Mudgett <rmudgett@digium.com>
* pri.c, pri_internal.h, pri_q931.h, q931.c, libpri.h: Add support
for calling and called subaddress. Partial support for COLP
subaddress. The Telecom Specs in NZ suggests that SUB ADDRESS is
always on, so doing "desk to desk" between offices each with an
asterisk box over the ISDN should then be possible, without a
whole load of DDI numbers required. (closes issue #15604)

Miscellaneous changes: * Removed unnecessary
Q931_IE_CONNECTED_NUM ie from setup_ack_ies[]. * Added internal

* q931.c: Conditional out noisy and redundant ASN.1 parse dump of
facility ie contents. 1) Outgoing messages have the facility ie
ASN.1 decoded and dumped when the ie is added to the message. The
whole message is then dumped. 2) Incoming messages have the
facility ie ASN.1 decoded and dumped when the ie is processed.
The whole message has already been dumped.
2009-10-07 18:34 +0000 [r1151-1152] Richard Mudgett <rmudgett@digium.com>
* pri_facility.c: Sent Q.SIG call rerouting message fixes. a)
Account for pSS1InfoElement where the bearer capability for the
new rerouted call is described. The call could be a fax or data
call, let's use the appropriate signaling to avoid call rejects
on the other end. b) Handle calling number appropriately, number
can be prohibited or non-existent. c) Add calling name if
available. d) Use the diversion counter from DivLegInfo2 (if was
present in the incoming Setup) and increment. (issue #14292)

* 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

2009-09-02 20:19 +0000 [r1059-1061] Richard Mudgett <rmudgett@digium.com>
* pri_internal.h, pri_q931.h, q931.c: Converted Q931_CALL_STATE_xxx
defines to an enum.
* 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.
2009-08-31 22:57 +0000 [r1042-1051] Richard Mudgett <rmudgett@digium.com>
* q931.c, libpri.h: Make event channel parameter encoding
consistent. Also make sure that service maintenance messages have
the channel id parameters reinitialized for each message since
they are sent over the global call reference.
* pri.c, pri_internal.h, q931.c, libpri.h: Split justsignalling
into cis_call and cis_auto_disconnect functionality.
2009-08-26 15:24 +0000 [r1006-1028] Richard Mudgett <rmudgett@digium.com>
* q931.c: Fix BRI PTP broken by -r790.
* q931.c: Put connected name in display ie for CONNECT message.
* q931.c: Fix ie ordering in some ie lists for send_message().
* q931.c: Make dump_channel_id() handle variable length fields.
Also did some other minor miscellaneous changes.
* q931.c: Make sure reversecharge is initialized.
2009-08-21 19:51 +0000 [r1000] Jason Parker <jparker@digium.com>
* Makefile: Add -n to ldconfig on HURD too. (closes issue #15130)

defines.
2009-08-18 23:53 +0000 [r982] Richard Mudgett <rmudgett@digium.com>
* rose.c, rosetest.c, rose_internal.h, pri.c, pri_internal.h,
Makefile, q931.c, rose.h, rose_etsi_diversion.c (added),
pri_facility.c, pri_facility.h, libpri.h, rose_etsi_ect.c
(added): Add COLP support to libpri for ETSI PTP, ETSI PTMP, and
Q.SIG. Add Connected Line Presentation (COLP) support to
chan_dahdi/libpri as an addition to issue 8824. This is the
libpri portion. COLP support is now available for ETSI PTP, ETSI
PTMP, and Q.SIG with this patch. (closes issue #14068) Tested by:

2009-08-07 15:53 +0000 [r968] Richard Mudgett <rmudgett@digium.com>
* rose_qsig_diversion.c: Corrected standard document reference.
2009-07-23 20:53 +0000 [r952] Richard Mudgett <rmudgett@digium.com>
* pri_facility.c: Fixed potential NULL pointer dereference.
2009-06-26 19:50 +0000 [r914-921] Richard Mudgett <rmudgett@digium.com>
* pri.c: Fix potential buffer overflow in pri_dump_info_str(). *
Created pri_snprintf() to prevent buffer overflow in
pri_dump_info_str(). * Extracted timer name to timer number table
from pri_timer2idx() so pri_dump_info_str() can use it.
* pri_internal.h: Eliminate local version of PRI_MAX_TIMERS.
* libpri.h: Doxygenify the timer comments.
* pri_internal.h, q931.c: Added printf format attribute to
pri_message() and pri_error() and fixed some detected errors.
2009-06-25 18:53 +0000 [r907] Sean Bright <sean@malleable.com>
* pri.c, pri_internal.h, q931.c, libpri.h: Add support for sending
Reverse Charging Indication IE on ISDN PRI. Add the ability to
transmit a Reverse Charging Indication IE during a SETUP message.
In passing, re-work some of the receive logic to be forwards
compatible with new RCI values that may be added in the future.
Also removed the PRI_REVERSECHARGE_SUPPORT define that I added on
the last commit since we can just check for
PRI_REVERSECHARGE_NONE or _REQUESTED on the Asterisk side to
determine support for this. Special thanks to rmudgett who could
have written this in half the time he spent reviewing it, but
instead talked me through it. Much appreciated! (issue #13760)

2009-06-25 17:35 +0000 [r894-901] Richard Mudgett <rmudgett@digium.com>
* libpri.h: Convert PRI_TIMER_xxx to an enum so PRI_MAX_TIMERS can
be automatically adjusted.
* pri.c, pri_timers.h (removed), libpri.h: Make it easier to add
more timers/counters and vary the defaults based upon switchtype.

* pri_facility.c: Miscellaneous minor changes.
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
characters.
* q931.c: Renamed callstate2str() to q931_call_state_str().
* q931.c: Made transmit_facility() debug message indiate to which
message the facility ie is being added.
2009-05-29 15:39 +0000 [r824] Richard Mudgett <rmudgett@digium.com>
* q931.c: Renamed local struct pri *pri variables to struct pri
*ctrl in q931.c. The context tagging for my editor is much
happier now that the struct and the variable do not have the same
name. (At least for this file.)
2009-05-20 15:03 +0000 [r804] Richard Mudgett <rmudgett@digium.com>
* q931.c: Removed usage of FUNC_DUMP(), FUNC_RECV(), and
FUNC_SEND() defines. They did not really help and hindered easy
lookup of parameter types.
2009-05-13 15:17 +0000 [r798] Kevin P. Fleming <kpfleming@digium.com>
* pri.c, pri_q931.h, q931.c, libpri.h: Add 'const' qualifier to
character string argument to keypad facility API calls These API
calls do not modify the string supplied, and should not be
allowed to modify it, so this patch adds a 'const' qualifier to
that argument to allow the compiler to enforce this restriction
(and allow callers of the API that already have a 'const' pointer
to be able to pass it to this API).
2009-05-07 16:21 +0000 [r790-794] Richard Mudgett <rmudgett@digium.com>
* pri_internal.h, pri_q931.h, q931.c: Minor code clean up.
* q931.c: Avoid a stale pointer crash if the TE BRI TEI is removed
when active calls exist. Made the q931_call record point to the
master D channel control structure instead of the BRI TEI
subchannel control structure. When a layer 3 message is sent, the
current TEI subchannel control structure is used.
2009-05-05 22:25 +0000 [r786] Richard Mudgett <rmudgett@digium.com>
* pri_q931.h: Added Q.931 call state description comments.
2009-05-01 22:47 +0000 [r782] Richard Mudgett <rmudgett@digium.com>

* pri.c, pri_internal.h, pri_q921.h, pri_q931.h, q921.c, q931.c,
libpri.h: Add service maintenance message support This adds
support for two new message types: Service and Service
Acknowledge. When a channel receives a service message it will
either take the channel in or out of service and then send a
service acknowledgment. Although not enforced here (enforced in
chan_dahdi), the service messages are only supported with switch
types 4ess/5ess. The required Asterisk changes will be coming
next. (issue #3450) Reported by: cmaj

* q921.c: A couple of last BRI fixes in libpri... don't discard
pending iframes when we call the q921_dchannel_up routine, since
we need to be able to send the ones that were queued up while the
D-channel went down and is being reactivated. Also fix some buggy
logic in the frame transmission decision code.
2009-01-22 21:48 +0000 [r675] Matthew Fredrickson <creslin@digium.com>
* q921.c: Change behavior so that we do not send I-frames when link
