ce59fabd5c clang compiler warnings: Fix invalid enum conversion
This patch fixes some invalid enum conversion warnings caught by clang. In
particular:
* chan_sip: Several functions mixed usage of the st_refresher_param
  enum and st_refresher enum. This patch corrects the functions to use the
  right enum.
* chan_pjsip: Fixed mixed usage of ast_sip_session_t38state and ast_t38_state.
* strings: Fixed incorrect usage of AO2 flags with strings container.
* res_stasis: Change a return enumeration to stasis_app_user_event_res.

61577cbee6 main/stdtime/localtime: Fix warning introduced in r433720
The patch in r433720 caused a warning to be kicked back by gcc. It occurred
due to this check in unistd.h:

    if (__nbytes > __bos0 (__buf))
        return __read_chk_warn (__fd, __buf, __nbytes, __bos0 (__buf));

That is, if __nbytes is greater than the result of GCC's built-in object size
for the struct, we'll kick back a warning.

As it turns out, this is because there is an error in the code in the patch.
We are passing the address of the pointer to the struct, not iev, which is a
pointer to the struct. Hence, the number of bytes is probably going to be lot
larger than the number of bytes that make up a pointer! This patch changes
the code just read from the pointer to the struct - which fixes the warning.

1cf949c489 clang compiler warnings: Fix warning for -Wgnu-variable-sized-type-not-at-end
This patch fixes a warning caught by clang, wherein a variable sized struct is
not located at the end of a struct. While the code in question actually
expected this, this is a good warning to watch for. Hence, this patch refactors
the code in question to not have two variable length elements in the same
struct.

28e3bd0af7 Improved and portable ast_log recursion avoidance
This introduces a new logger routine ast_log_safe.  This routine should be
used for all error messages in code that can be run as a result of ast_log.
ast_log_safe does nothing if run recursively.  All error logging in
astobj2.c, strings.c and utils.h have been switched to ast_log_safe.

This required adding support for raw threadstorage.  This provides direct
access to the void* pointer in threadstorage.  In ast_log_safe, NULL is used
to signify that this thread is not already running ast_log_safe, (void*)1 when
it is already running.  This was done since it's critical that ast_log_safe
do nothing that could log during recursion checking.

3ddd92902a Replace most uses of ast_register_atexit with ast_register_cleanup.
Since 'core stop now' and 'core restart now' do not stop modules,
it is unsafe for most of the core to run cleanups.  Originally all
cleanups used ast_register_atexit, and were only changed when it
was shown to be unsafe.  ast_register_atexit is now used only when
absolutely required to prevent corruption and close child processes.

Exceptions that need to use ast_register_atexit:
* CDR: Flush records.
* res_musiconhold: Kill external applications.
* AstDB: Close the DB.
* canary_exit: Kill canary process.

ab674f67b5 app_confbridge: file playback blocks dtmf
Attempting to execute DTMF in a confbridge while file playback (prompt,
announcement, etc) is occurring is not allowed. You have to wait until
the sound file has completed before entering DTMF. This patch fixes it
so that app_confbridge now monitors for dtmf key presses during menu
driven file playback. If a key is pressed playback stops and it executes
the matched menu option.

abf3e40902 dns: Add core DNS API + unit tests and res_resolver_unbound module + unit tests.
This change adds an abstracted core DNS API which resembles the API described
here[1]. The API provides a pluggable mechanism for resolvers and also a
consistent view for records. Both synchronous and asynchronous queries are
supported.

This change also adds a res_resolver_unbound module which uses the libunbound
library to provide resolution.

Unit tests have also been written for all of the above to confirm the API and
functionality.

c41dd32b94 Audit ast_sockaddr_resolve() usage for memory leaks.
Valgrind found some memory leaks associated with ast_sockaddr_resolve().
Most of the leaks had already been fixed by earlier memory leak hunt
patches.  This patch performs an audit of ast_sockaddr_resolve() and found
one more.

* Fix ast_sockaddr_resolve() memory leak in
apps/app_externalivr.c:app_exec().

* Made main/netsock2.c:ast_sockaddr_resolve() always set the addrs
parameter for safety so the pointer will never be uninitialized on return.
The same goes for res/res_pjsip_acl.c:extract_contact_addr().

* Made functions that call ast_sockaddr_resolve() with RAII_VAR()
controlling the addrs variable use ast_free instead of ast_free_ptr to
provide better MALLOC_DEBUG information.

e89f83b3ad main/frame: Don't report empty disallow values as an error
In realtime, it is normal to have a database with both 'allow' and 'disallow'
columns in the schema. It is perfectly valid to have an 'allow' value of
'!all,g722,ulaw,alaw' and no 'disallow' value. Unlike in static conf files,
you can't *not* provide the disallow value. Thus, the empty disallow value
causes a spurious WARNING message, which is kind of annoying.

This patch makes it so that a 'disallow' value with no ... value ... is
ignored. Granted, you can still screw this up as well, as technically
specifying 'disallow=all,!ulaw' allows only ulaw, and then you would have no
'allow' value in your database. But really, why would you do that? WHY?

38ee441ea7 main/audiohook: Update internal sample rate on reads
When an audiohook is created (which is used by the various Spy applications
and Snoop channel in Asterisk 13+), it initially is given a sample rate of
8kHz. It is expected, however, that this rate may change based on the media
that passes through the audiohook. However, the read/write operations on the
audiohook behave very differently.

When a frame is written to the audiohook, the format of the frame is checked
against the internal sample rate. If the rate of the format does not match
the internal sample rate, the internal sample rate is updated and a new SLIN
format is chosen based on that sample rate. This works just fine.

When a frame is read, however, we do something quite different. If the format
rate matches the internal sample rate, all is fine. However, if the rates
don't match, the audiohook attempts to "fix up" the number of samples that
were requested. This can result in some seriously large number of samples
being requested from the read/write factories.

Consider the worst case - 192kHz SLIN. If we attempt to read 20ms worth of
audio produced at that rate, we'd request 3840 samples (192000 / (1000 / 20)).
However, if the audiohook is still expecting an internal sample rate of 8000,
we'll attempt to "fix up" the requested samples to:

  samples_converted = samples * (ast_format_get_sample_rate(format) /
                                 (float) audiohook->hook_internal_samp_rate);

  which is:

  92160 = 3840 * (192000 / 8000)

This results in us attempting to read 92160 samples from our factories, as
opposed to the 3840 that we actually wanted. On a 64-bit machine, this
miraculously survives - despite allocating up to two buffers of length 92160
on the stack. The 32-bit machines aren't quite so lucky. Even in the case where
this works, we will either (a) get way more samples than we wanted; or (b) get
about 3840 samples, assuming the timing is pretty good on the machine.

Either way, the calculation being performed is wrong, based on the API users
expectations.

My first inclination was to allocate the buffers on the heap. As it is,
however, there's at least two drawbacks with doing this:
(1) It's a bit complicated, as the size of the buffers may change during the
    lifetime of the audiohook (ew).
(2) The stack is faster (yay); the heap is slower (boo).

Since our calculation is flat out wrong in the first place, this patch fixes
this issue by instead updating the internal sample rate based on the format
passed into the read operation. This causes us to read the correct number of
samples, and has the added benefit of setting the audihook with the right
SLIN format.

Note that this issue was caught by the Asterisk Test Suite as a result of
r432195 in the 13 branch. Because this issue is also theoretically possible
in Asterisk 11, the change is being made here as well.

29304d10a0 Add support for the clang compiler; update RAII_VAR to use BlocksRuntime
RAII_VAR, which is used extensively in Asterisk to manage reference counted
resources, uses a GCC extension to automatically invoke a cleanup function
when a variable loses scope. While this functionality is incredibly useful
and has prevented a large number of memory leaks, it also prevents Asterisk
from being compiled with clang.

This patch updates the RAII_VAR macro such that it can be compiled with clang.
It makes use of the BlocksRuntime, which allows for a closure to be created
that performs the actual cleanup.

Note that this does not attempt to address the numerous warnings that the clang
compiler catches in Asterisk.

Much thanks for this patch goes to:
* The folks on StackOverflow who asked this question and Leushenko for
  providing the answer that formed the basis of this code:
  http://stackoverflow.com/questions/24959440/rewrite-gcc-cleanup-macro-with-nested-function-for-clang
* Diederik de Groot, who has been extremely patient in working on getting this
  patch into Asterisk.

79e9b37ad0 localtime: Fix file descriptor leak on kqueue(2) systems
The localtime management in the Asterisk core contains a thread that watches
for changes in the local timezone. On systems where the directory containing
/etc/localtime is modified frequently, the thread monitoring the changes will
be woken up to determine if any changes in timezone have occurred. When using
kqueue(2), this can cause a leak of file descriptors due to some improper
management of resources.

This patch updates the kqueue(2) handling in localtime, such that is no longer
leaks resources.

41ba8fd7c0 translate: Prevent invalid memory accesses on fast shutdown
When a 'core restart now' or 'core stop now' is executed and a channel is
currently in a media operation, the translator matrix can be destroyed while a
channel is currently blocked on getting the best translation choice
(see ast_translator_best_choice). When the channel gets the mutex, the
translation matrix now has invalid memory, and Asterisk crashes.

This patch does two things:
(1) We now only clean up the translation matrix on a graceful shutdown. In that
    case, there are no channels, and so there is no risk of this occurring.
(2) We also now set the __matrix and __indextable to NULL. In some initial
    backtraces when this occurred, it looked as if there was a memory corruption
    occurring, and it wasn't until we determined that something had restarted
    Asterisk that the issue became clear. By setting these to NULL on shutdown,
    it becomes a bit easier to determine why a crash is occurring.

Note that we could litter the code with NULL checks on the __matrix, but the
act of making the translation matrix cleaned up on shutdown should preclude
this issue from occurring in the first place, and this part of the code needs
to be as fast as possible.

d79670b269 Dial API: add self destruct option when complete
This patch adds a self-destruction option to the
dial api.  The usefulness of this is mostly when
using async mode to spawn a separate thread used
to handle the new call, while the calling thread
is allowed to go on about other business.

The only alternative to this option would be the
calling thread spawning a new thread, or hanging
around itself waiting to destroy the dial struct
after completion.

Example of use (minus error checking):

  struct ast_dial *dial = ast_dial_create();

  ast_dial_append(dial, "PJSIP", "200", NULL);

  ast_dial_option_global_enable(dial, AST_DIAL_OPTION_ANSWER_EXEC, "Echo");
  ast_dial_option_global_enable(dial, AST_DIAL_OPTION_SELF_DESTROY, NULL);

  ast_dial_run(dial, NULL, 1);

The dial_run call will return almost immediately
after spawning the new thread to run and monitor
the dial.  If the call is answered, it is placed
into the echo app.  When completed, it will call
ast_dial_destroy() on the dial structure.

Note that any allocations made to pass values to
ast_dial_set_user_data() or dial options must be
free'd in a state callback function on any of:
  AST_DIAL_RESULT_UNASWERED,
  AST_DIAL_RESULT_ANSWERED,
  AST_DIAL_RESULT_HANGUP, or 
  AST_DIAL_RESULT_TIMEOUT.

d68012d1a3 channels/sip/sdp_crypto: Handle SRTP keys negotiated with key lifetime/MKI
Prior to this patch, SDP offers negotiating SDES-SRTP crypto attributes would
be rejected if those crypto attributes contained either a key lifetime or a
MKI parameter. While from a theoretical point of view this was defensible -
Asterisk does not support key lifetimes or multiple crypto keys - from a
practical point of view, this is quite a problem. A large number of endpoints
offer lifetimes/MKI, which Asterisk can tolerate so long as it doesn't actually
have to support anything more than a single key or refresh the key.
In reality, this is (so far as we've seen) always the case.

This patch is a forward port of Olle's work in the lingon-srtp-key-lifetime-1.8
branch. To quote Olle from ASTERISK-17721, it handles lifetime/MKI parameters
in the following fashion:

> The Lingon branch now handle lifetime and MKI parameters.
>
> We only accept lifetimes up to max for the crypto and higher than 10 hours
> for packetization of 20 ms (50 pps).
>
> We only handle MKI with index 1.
>
> We do not really bother with counting packets and reinviting at end of
> lifetime, so the min of 10 hours kind of takes care of most calls. If there
> are longer ones, we rely on the other side for re-invites.
>
> It's still not perfect, but I personally think this is an improvement. A
> configuration option for minimum lifetime accepted could be added.

When the patch was ported forward, I decided against adding a configuration
option as Olle's handling was more than sufficient for every case I've seen
come through the issue tracker or through interoperability testing. We can
revisit that decision if it proves to be false.

A few small other tweaks were made to the surrounding code to reduce
indentation and provide better type safety for the 'tag' parameter.

a528dfc9a7 ARI/PJSIP: Apply requesting channel's format cap to created channels
This patch addresses the following problems:
* ari/resource_channels: In ARI, we currently create a format capability
  structure of SLIN and apply it to the new channel being created. This was
  originally done when the PBX core was used to create the channel, as there
  was a condition where a newly created channel could be created without any
  formats. Unfortunately, now that the Dial API is being used, this has two
  drawbacks:
  (a) SLIN, while it will ensure audio will flows, can cause a lot of
      needless transcodings to occur, particularly when a Local channel is
      created to the dialplan. When no format capabilities are available, the
      Dial API handles this better by handing all audio formats to the requsted
      channels. As such, we defer to that API to provide the format
      capabilities.
  (b) If a channel (requester) is causing this channel to be created, we
      currently don't use its format capabilities as we are passing in our own.
      However, the Dial API will use the requester channel's formats if none
      are passed into it, and the requester channel exists and has format
      capabilities. This is the "best" scenario, as it is the most likely to
      create a media path that minimizes transcoding.
  Fixing this simply entails removing the providing of the format capabilities
  structure to the Dial API.

* chan_pjsip: Rather than blindly picking the first format in the format
  capability structure - which actually *can* be a video or text format - we
  select an audio format, and only pick the first format if that fails. That
  minimizes the weird scenario where we attempt to transcode between video/audio.

* res_pjsip_sdp_rtp: Applied the joint capapbilites to the format structure.
  Since ast_request already limits us down to one format capability once the
  format capabilities are passed along, there's no reason to squelch it here.

* channel: Fixed a comment. The reason we have to minimize our requested
  format capabilities down to a single format is due to Asterisk's inability
  to convey the format to be used back "up" a channel chain. Consider the
  following:

    PJSIP/A => L;1 <=> L;2 => PJSIP/B
    g,u,a     g,u,a    g,u,a      u

  That is, we have PJSIP/A dialing a Local channel, where the Local;2 dials
  PJSIP/B. PJSIP/A has native format capabilities g722,ulaw,alaw; the Local
  channel has inherited those format capabilities down the line; PJSIP/B
  supports only ulaw. According to these format capabilities, ulaw is
  acceptable and should be selected across all the channels, and no
  transcoding should occur. However, there is no way to convey this: when L;2
  and PJSIP/B are put into a bridge, we will select ulaw, but that is not
  conveyed to PJSIP/A and L;1. Thus, we end up with:

    PJSIP/A <=> L;1 <=> L;2 <=> PJSIP/B
      g          g   X   u        u

  Which causes g722 to be written to PJSIP/B.

  Even if we can convey the 'ulaw' choice back up the chain (which through
  some severe hacking in Local channels was accomplished), such that the chain
  looks like:

    PJSIP/A <=> L;1 <=> L;2 <=> PJSIP/B
      u          u       u         u

  We have no way to tell PJSIP/A's *channel driver* to Answer in the SDP back
  with only 'ulaw'. This results in all the channel structures being set up
  correctly, but PJSIP/A *still* sending g722 and causing the chain to fall
  apart.

  There's a lot of difficulty just in setting this up, as there are numerous
  race conditions in the act of bridging, and no clean mechanism to pass the
  selected format backwards down an established channel chain. As such, the
  best that can be done at this point in time is clarifying the comment.

252aee4228 ISDN AOC: Fix crash from an AOC-E message that doesn't have a channel association.
Processing an AOC-E event that does not or no longer has a channel
association causes a crash.

The problem with posting AOC events to the channel topic is that AOC-E
events don't always have a channel association and posting the event to
the all channels topic is just wrong.  AOC-E events do however have their
own charging association method to refer to the agreement with the
charging entity.

* Changed the AOC events to post to the AMI manager topic instead of the
channel topics.  If a channel is associated with the event then channel
snapshot information is supplied with the AMI event.

* Eliminated RAII_VAR() usage in aoc_to_ami() and ast_aoc_manager_event().

e2d3215b83 HTTP: Stop accepting requests on final system shutdown.
There are three CLI commands to stop and restart Asterisk each.

1) core stop/restart now - Hangup all calls and stop or restart Asterisk.
New channels are prevented while the shutdown request is pending.

2) core stop/restart gracefully - Stop or restart Asterisk when there are
no calls remaining in the system.  New channels are prevented while the
shutdown request is pending.

3) core stop/restart when convenient - Stop or restart Asterisk when there
are no calls in the system.  New calls are not prevented while the
shutdown request is pending.

ARI has made stopping/restarting Asterisk more problematic.  While a
shutdown request is pending it is desirable to continue to process ARI
HTTP requests for current calls.  To handle the current calls while a
shutdown request is pending, a new committed to shutdown phase is needed
so ARI applications can deal with the calls until the system is fully
committed to shutdown.

* Added a new shutdown committed phase so ARI applications can deal with
calls until the final committed to shutdown phase is reached.

* Made refuse new HTTP requests when the system has reached the final
system shutdown phase.  Starting anything while the system is actively
releasing resources and unloading modules is not a good thing.

* Split the bridging framework shutdown to not cleanup the global bridging
containers when shutting down in a hurry.  This is similar to how other
modules prevent crashes on rapid system shutdown.

* Moved ast_begin_shutdown(), ast_cancel_shutdown(), and
ast_shutting_down().  You should not have to include channel.h just to
access these system functions.

03ce56d6c5 sorcery: Don't try to load object types which haven't been defined.
The act of defining wizards for an object type in sorcery.conf will
create a minimal object type. This can cause a problem when a module
has multiple sorcery instances (which all get the wizards from sorcery.conf
applied) but the sorcery instances do not all contain full information
about the object types. Upon loading errors will occur stating that
the objects can not be created. This is confusing and is actually
perfectly fine.

This change makes it so that only object types which have been fully
defined will be loaded.

6a76740b83 HTTP: For httpd server, need option to define server name for security purposes
Added a new config property [servername] to the http.conf file; updated the http server to use the new property when sending responses, for showing http status through the CLI and when reporting status through the 'httpstatus' webpage. In this version, [servername] is uncommented by default.

388d691f34 stasis transfer: fix stasis bridge push race part two
When swapping a Local channel in place of one already
in a bridge (to complete a bridge attended transfer),
the channel that was swapped out can actually be hung
up before the stasis bridge push callback executes on
the independant transfer thread.  This results in the
stasis app loop dropping out and removing the control
that has the the app name which the local replacement
channel needs so it can re-enter stasis.

To avoid this race condition a new push_peek callback
has been added, and called from the ast_bridge_impart
thread before it launches the independant thread that
will complete the transfer.  Now the stasis push_peek
callback can copy the stasis app name before the swap
channel can hang up.

69e107b24e res_pjsip_outbound_registration: Fix reload race condition.
Performing a CLI "module reload" command when there are new pjsip.conf
registration objects defined frequently failed to load them correctly.

What happens is a race condition between res_pjsip pushing its reload into
an asynchronous task processor task and the thread that does the rest of
the reloads when it gets to reloading the res_pjsip_outbound_registration
module.  A similar race condition happens between a reload and the CLI/AMI
show registrations commands.  The reload updates the current_states
container and the CLI/AMI commands call get_registrations() which builds a
new current_states container.

* Made res_pjsip.c reload_module() use ast_sip_push_task_synchronous()
instead of ast_sip_push_task() to eliminate two threads processing config
reloads at the same time.

* Made get_registrations() not replace the global current_states container
so the CLI/AMI show registrations command cannot interfere with reloading.
You could never add/remove objects in the container without the
possibility of the container being replaced out from under you by
get_registrations().

* Added a registration loaded sorcery instance observer to purge any dead
registration objects since get_registrations() cannot do this job anymore.
The struct ast_sorcery_instance_observer callbacks must be used because
the callback happens inline with the load process.  The struct
ast_sorcery_observer callbacks are pushed to a different thread.

* Added some global current_states NULL pointer checks in case the
container disappears because of unload_module().

* Made sorcery's struct ast_sorcery_instance_observer.object_type_loaded
callbacks guaranteed to be called before any struct
ast_sorcery_observer.loaded callbacks will be called.

* Moved the check for non-reloadable objects to before the sorcery
instance loading callbacks happen to short circuit unnecessary work.
Previously with non-reloadable objects, the sorcery instance
loading/loaded callbacks would always happen, the individual wizard
loading/loaded would be prevented, and the non-reloadable type logging
message would be logged for each associated wizard.

c7591ef6bc tcptls: Bad file descriptor error when reloading chan_sip
While running through some scenarios using chan_sip and tcp a problem would
occur that resulted in a flood of bad file descriptor messages on the cli:

tcptls.c:712 ast_tcptls_server_root: Accept failed: Bad file descriptor

The message is received because the underlying socket has been closed, so is
valid. This is probably happening because unloading of chan_sip is not atomic.
That however is outside the scope of this patch. This patch simply stops the
logging of multiple occurrences of that message.
