  chan_sip: Fix RTCP port for SRFLX ICE candidates
  
  This corrects one-way audio between Asterisk and Chrome/jssip as a
  result of Asterisk inserting the incorrect RTCP port into RTCP SRFLX
  ICE candidates. This also exposes an ICE component enumeration to
  extract further details from candidates.

  res_rtp_asterisk: Fails to resume WebRTC call from hold
  
  In ast_rtp_ice_start if the ice session create check list failed, start check
  was never initiated and ice_started was never set to true.  Upon re-entering
  the function (for instance, [un]hold) it would try to create the check list
  again with duplicate remote candidates.
  
  Fixed so that if the create check list fails the necessary data structures
  are properly re-initialized for any subsequent retries.
  
  Note, it was decided to not stop ice support (by calling ast_rtp_ice_stop) on a
  check list failure because it possible things might still work.  However, a
  debug message was added to help with any future troubleshooting.

  res_rtp_asterisk: Fix checklist creating problems in ICE sessions
  
  Prior to this patch, local candidate lists including SRFLX would fail to start
  properly when building ICE candidate check lists. This patch fixes that problem
  by making sure that each SRFLX candidate is associated with the proper
  base address so that the check list can create matches properly.
  This patch was written by jcolp. The issue will be left open to await testing
  by the issue participants.

  res_rtp_asterisk: Add support for DTLS handshake retransmissions
  
  On congested networks, it is possible for the DTLS handshake messages to get
  lost. This patch adds a timer to res_rtp_asterisk that will periodically
  check to see if the handshake has succeeded. If not, it will retransmit the
  DTLS handshake.

fd6e829c82 AST-2014-007: Fix DOS by consuming the number of allowed HTTP connections.
Simply establishing a TCP connection and never sending anything to the
configured HTTP port in http.conf will tie up a HTTP connection.  Since
there is a maximum number of open HTTP sessions allowed at a time you can
block legitimate connections.

A similar problem exists if a HTTP request is started but never finished.

* Added http.conf session_inactivity timer option to close HTTP
connections that aren't doing anything.  Defaults to 30000 ms.

* Removed the undocumented manager.conf block-sockets option.  It
interferes with TCP/TLS inactivity timeouts.

* AMI and SIP TLS connections now have better authentication timeout
protection.  Though I didn't remove the bizzare TLS timeout polling code
from chan_sip.

* chan_sip can now handle SSL certificate renegotiations in the middle of
a session.  It couldn't do that before because the socket was non-blocking
and the SSL calls were not restarted as documented by the OpenSSL
documentation.

* Fixed an off nominal leak of the ssl struct in
handle_tcptls_connection() if the FILE stream failed to open and the SSL
certificate negotiations failed.

The patch creates a custom FILE stream handler to give the created FILE
streams inactivity timeout and timeout after a specific moment in time
capability.  This approach eliminates the need for code using the FILE
stream to be redesigned to deal with the timeouts.

This patch indirectly fixes most of ASTERISK-18345 by fixing the usage of
the SSL_read/SSL_write operations.

4b07aa5f13 chan_sip: Hangup transferer/transferee when transfer to Parking fails
When performing a SIP transfer to a Park extension, if the Park fails, chan_sip
will currently not hang up either the transferer or the transfer target. This
results in the channels being orphaned with no thread to service frames,
resulting in stuck channels.

This patch immediately hangs up the two channels if a Park fails.

c58bab8ce3 AST-2013-005: Fix crash caused by invalid SDP
If the SIP channel driver processes an invalid SDP that defines media
descriptions before connection information, it may attempt to reference
the socket address information even though that information has not yet
been set. This will cause a crash.

This patch adds checks when handling the various media descriptions that
ensures the media descriptions are handled only if we have connection
information suitable for that media.

Thanks to Walter Doekes, OSSO B.V., for reporting, testing, and providing

4fd979228d AST-2013-004: Fix crash when handling ACK on dialog that has no channel
A remote exploitable crash vulnerability exists in the SIP channel driver if an
ACK with SDP is received after the channel has been terminated. The handling
code incorrectly assumed that the channel would always be present.

This patch adds a check such that the SDP will only be parsed and applied if
Asterisk has a channel present that is associated with the dialog.

Note that the patch being applied was modified only slightly from the patch

88a5f18dec Fix Not Storing Current Incoming Recv Address
In 1.8, r384779 introduced a regression by retrieving an old dialog and keeping
the old recv address since recv was already set.  This has caused a problem when
a proxy is involved since responses to incoming requests from the proxy server,
after an outbound call is established, are never sent to the correct recv
address.

In 11, r382322 introduced this regression.

The fix is to revert that change and always store the recv address on incoming
requests.

Thank you Walter Doekes for helping to point out this error and Mark Michelson
for your input/review of the fix.

1e03a50878 Fix Registration Failure When A Peer And TLS Are Used
If a peer is used in a register line and TLS is defined as the transport, the
registration fails since the transport on the dialog is never set properly
resulting in UDP being used instead of TLS.

This patch sets the dialog's transport based on the transport that was defined
in the register line.  If the register line does not specify a transport, the
parsing function for the register line always defaults back to UDP.

eec46f56f4 Fix Crash Caused By One-way Audio With auto_* NAT Settings Fix
The prior code committed, r385473, failed to take into consideration that not
all outgoing calls will be to a peer.  My fault.

This patch does the following:

* Check if there is a related peer involved.  If there is, check and set NAT 
  settings according to the peer's settings.

* Fix a problem with realtime peers.  If the global setting has auto_force_rport
  set and we issued a "sip reload" while a peer is still registered, the peer's
  flags for NAT are reset to off.  When this happens, we were always setting the
  contact address of the peer to that of the full contact info that we had.

527a611c80 chan_sip: NOTIFYs for BLF start queuing up and fail to be sent out after retries fail
RFC6665 4.2.2: ... after a failed State NOTIFY transaction remove the subscription

The problem is that the State Notify requests rely on the 200OK reponse for pacing control
and to not confuse the notify susbsystem.
The issue is, the pendinginvite isn't cleared if a response isn't received,
thus further notify's are never sent.

The solution, follow RFC 6665 4.2.2's 'SHOULD' and remove the subscription after failure.

aec4d2f239 chan_sip: Session-Expires: Set timer to correctly expire at (~2/3) of the interval when not the refresher
RFC 4028 Section 10
	if the side not performing refreshes does not receive a
	session refresh request before the session expiration, it SHOULD send
	a BYE to terminate the session, slightly before the session
	expiration.  The minimum of 32 seconds and one third of the session
	interval is RECOMMENDED.

Prior to this asterisk would refresh at 1/2 the Session-Expires interval,
or if the remote device was the refresher, asterisk would timeout at interval end.

Now, when not refresher, timeout as per RFC noted above.

2846881045 chan_sip: Honor Session-Expires in 200OK response when it's a RE-INVITE when asterisk is the refresher.
RFC 4028 Section 7.2
 "UACs MUST be prepared to receive a Session-Expires header field in a
 response, even if none were present in the request." 

What changed
  After ASTERISK-20787, inbound calls to asterisk with no Session-Expires in the INVITE are now are offered
  a Session-Expires (1800 asterisk default) in the response, with asterisk as the refresher.

Symptom:
  After 900 seconds (asterisk default refresher period 1800), asterisk RE-INVITEs the device, the device
   may respond with a much lower Session-Expires (180 in our case) value that it is now using.

  Asterisk ignores this response, as it's deemed both an INBOUND CALL, and a RE-INVITE.

  After 180 seconds the device times out and sends BYE (hangs up), asterisk is still working with the
  refresher period of 1800 as it ignored the 'Session Expires: 180' in the previous 200OK response.
 
Fix:
	handle_response_invite() when 200OK, remove check for outbound and reinvite.

95dcae4aa6 Prevent crash in 'sip show peers' when the number of peers on a system is large
When you have lots of SIP peers (according to the issue reporter, around 3500),
the 'sip show peers' CLI command or AMI action can crash due to a poorly placed
string duplication that occurs on the stack. This patch refactors the command
to not allocate the string on the stack, and handles the formatting of a single
peer in a separate function call.

f07cccecfd Fix One-Way Audio With auto_* NAT Settings When SIP Calls Initiated By PBX
When we reload Asterisk or chan_sip, the flags force_rport and comedia that are
turned on and off when using the auto_force_rport and auto_comedia nat settings
go back to the default setting off.  These flags are turned on when needed or
off when not needed at the time that a peer registers, re-registers or initiates
a call.  This would apply even when only the default global setting
"nat=auto_force_rport" is being used, which in this case would only affect the
force_rport flag.

Everything is good except for the following:  The nat setting is set to
auto_force_rport and auto_comedia.  We reload Asterisk and the peer's
registration has not expired.  We load in the settings for the peer which turns
force_rport and comedia back to off.  Since the peer has not re-registered or
placed a call yet, those flags remain off.  We then initiate a call to the peer
from the PBX.  The force_rport and comedia flags stay off.  If NAT is involved,
we end up with one-way audio since we never checked to see if the peer is behind
NAT or not.

This patch does the following:

* Moves the checking of whether a peer is behind NAT into its own function

* Create a function to set the peer's NAT flags if they are using the auto_* NAT
  settings

* Adds calls in sip_request_call() to these new functions in order to setup the
  dialog according to the peer's settings

9511761e81 Fix crash in chan_sip when a core initiated op occurs at the same time as a BYE
When a BYE request is processed in chan_sip, the current SIP dialog is detached
from its associated Asterisk channel structure. The tech_pvt pointer in the
channel object is set to NULL, and the dialog persists for an RFC mandated
period of time to handle re-transmits.

While this process occurs, the channel is locked (which is good).
Unfortunately, operations that are initiated externally have no way of knowing
that the channel they've just obtained (which is still valid) and that they are
attempting to lock is about to have its tech_pvt pointer removed. By the time
they obtain the channel lock and call the channel technology callback, the
tech_pvt is NULL.

This patch adds a few checks to some channel callbacks that make sure the
tech_pvt isn't NULL before using it. Prime offenders were the DTMF digit
callbacks, which would crash if AMI initiated a DTMF on the channel at the
same time as a BYE was received from the UA. This patch also adds checks on
sip_transfer (as AMI can also cause a callback into this function), as well
as sip_indicate (as lots of things can queue an indication onto a channel).

74c57919a4 Fix For Not Overriding The Default Settings In chan_sip
The initial report was that the "nat" setting in the [general] section was not
having any effect in overriding the default setting.  Upon confirming that this
was happening and looking into what was causing this, it was discovered that
other default settings would not be overriden as well.

This patch works similar to what occurs in build_peer().  We create a temporary
ast_flags structure and using a mask, we override the default settings with
whatever is set in the [general] section.

In the bug report, the reporter who helped to test this patch noted that the
directmedia settings were being overriden properly as well as the nat settings.

This issue is also present in Asterisk 1.8 and a separate patch will be applied
to it.

b984d78c5c AST-2013-003: Prevent username disclosure in SIP channel driver
When authenticating a SIP request with alwaysauthreject enabled, allowguest
disabled, and autocreatepeer disabled, Asterisk discloses whether a user
exists for INVITE, SUBSCRIBE, and REGISTER transactions in multiple ways. The
information is disclosed when:
 * A "407 Proxy Authentication Required" response is sent instead of a
   "401 Unauthorized" response
 * The presence or absence of additional tags occurs at the end of "403
   Forbidden" (such as "(Bad Auth)")
 * A "401 Unauthorized" response is sent instead of "403 Forbidden" response
   after a retransmission
 * Retransmission are sent when a matching peer did not exist, but not when a
   matching peer did exist.

This patch resolves these various vectors by ensuring that the responses sent
in all scenarios is the same, regardless of the presence of a matching peer.

This issue was reported by Walter Doekes, OSSO B.V. A substantial portion of
the testing and the solution to this problem was done by Walter as well - a
huge thanks to his tireless efforts in finding all the ways in which this
setting didn't work, providing automated tests, and working with Kinsey on
getting this fixed.

1eff40f21d Resolve deadlock between SIP registration and channel based functions
In r373424, several reentrancy problems in chan_sip were addressed. As a
result, the SIP channel driver is now properly locking the channel driver
private information in certain operations that it wasn't previously. This
exposed two latent problems either in register_verify or by functions called
by register_verify. This includes:
 * Holding the private lock while calling sip_send_mwi_to_peer. This can create
   a new sip_pvt via sip_alloc, which will obtain the channel container lock.
   This is a locking inversion, as any channel related lock must be obtained
   prior to obtaining the SIP channel technology private lock.

   Note that this issue was already fixed in Asterisk 11.

 * Holding the private lock while calling sip_poke_peer. In the same vein as
   sip_send_mwi_to_peer, sip_poke_peer can create a new SIP private, causing
   the same locking inversion.

Note that this locking inversion typically occured when CLI commands were run
while a SIP REGISTER request was being processed, as many CLI commands (such
as 'sip show channels', 'core show channels', etc.) have to obtain the channel
container lock.

4a50764715 tcptls: Prevent unsupported options from being set
AMI, HTTP, and chan_sip all support TLS in some way, but none of them
support all the options that Asterisk's TLS core is capable of
interpreting. This prevents consumers of the TLS/SSL layer from setting
TLS/SSL options that they do not support.

This also gets tlsverifyclient closer to a working state by requesting
the client certificate when tlsverifyclient is set. Currently, there is
no consumer of main/tcptls.c in Asterisk that supports this feature and
so it can not be properly tested.

When a session timer expires during a dialog that has re-negotiated to T.38

2109e47109 Fix / Clean Up Some Items To Handle The New auto_* NAT Options
The original report had to do with a realtime peer behind NAT being pruned and
the peer's private address being used instead of its external address.  Upon
debugging, it was discovered that this was being caused by the addition of
the auto_force_rport and auto_comedia settings.

This patch does the following:

* Adds a missing note to the CHANGES file indicating that the default global nat
  setting is auto_force_rport

* Constify the 'req' parameter for check_via()

* Add calls to check_via() in a couple of places in order for the auto_*
  settings to do their job in attempting to determine if NAT is involved

* Set the flags SIP_NAT_FORCE_RPORT and SIP_PAGE2_SYMMETRICRTP if the auto_*
  settings are in use where it was needed

* Moves the copying of peer flags up in build_peer() to before they are used;
  this fixes the realtime prune issue

* Update the contrib/realtime schemas to allow the nat column to handle the
  different nat setting combinations we have

This patch received a review and "Ship It!" on the issue itself.

Previously, presencestate information was sent whenever the state was not
NOT_SET. When r381594 actually returned INVALID presence state in all the
places it was supposed to, it caused chan_sip to start adding presence
state information to NOTIFY requests that it previously would not have
added. chan_sip shouldn't be adding presence state information when the
provider is in an invalid state; users can't set the state to invalid and
an invalid state always implies that the provider is in an error condition.

a70075ce10 Fix a crash that occurred when a BYE was received on a replaced dialog.
Reference counting for the channel and its tech_pvt got messed up at
some point between 1.8 and 11. The result was that if a BYE for a dialog
that had been replaced (via an INVITE with Replaces) was received, Asterisk
would crash due to trying to access data on a channel that was no longer there.

The fix I introduced is to remove code that both unrefs the sip_pvt and sets
the channel's tech_pvt to NULL when an INVITE with Replaces is handled. This
way when a BYE is received, the tech_pvt will be non-NULL and so the BYE can
be processed and not cause a crash.

1412adf576 Process session timers, even if Session-Expires header is missing
Previously, Asterisk only processed session timer information if both the
'Supported: timer' and 'Session-Expires' headers were present. However, the
Session-Expires header is optional. If we were to receive a request with a
Min-SE greater than our configured session-expires, we would respond with a
'Session-Expires' header that was too small.

This patch cleans the situation up a bit, always processing timer information
if the 'Supported: timer' header is present.

df83528506 Unregister SIP provider API if module load is declined
A user in #asterisk ran into a problem where a configuration error prevented
the chan_sip module from being loaded. Upon fixing their configuratione error,
they could no longer load the chan_sip module. This was because the
configuration checking happened after the SIP provider was registered with the
Asterisk core, and subsequent attempts to load the SIP module failed as the
provider was already registered.

Since we want to detect any failure in registering chan_sip as early as
possible (as that could be emblematic of a deeper mismatch between module
and Asterisk core), this patch does not change the registration location, but
does ensure that if a module load is declined, we unregister the module as
the SIP api provider.
