Matthew Jordan c4f013c5c8 Re-initialize logmsgs mutex upon logger initialization to prevent lock errors
Similar to the patch that moved the fork earlier in the startup sequence to
prevent mutex errors in the recursive mutex surrounding the read/write thread
registration lock, this patch re-initializes the logmsgs mutex.  Part of the
start up sequence before forking the process into the background includes
reading asterisk.conf; this has to occur prior to the call to daemon in order
to read startup parameters.  When reading in a conf file, log statements can
be generated.  Since this can't be avoided, the mutex instead is
re-initialized to ensure a reset of any thread tracking information.

This patch also includes some additional debugging to catch errors when
locking or unlocking the recursive mutex that surrounds locks when the
DEBUG_THREADS build option is enabled.  DO_CRASH or THREAD_CRASH will
cause an abort() if a mutex error is detected.

Walter Doekes 65c8d16d79 Fix most leftover non-opaque ast_str uses.
Instead of calling str->str, one should use ast_str_buffer(str). Same
goes for str->used as ast_str_strlen(str) and str->len as
ast_str_size(str).

Matthew Jordan 2bb01eb0ff Reorder startup sequence to prevent lockups when process is sent to background
Although it is very rare and timing dependent, the potential exists for the
call to 'daemon' to cause what appears to be a deadlock in Asterisk during
startup.  This can occur when a recursive mutex is obtained prior to the
daemon call executing.  Since daemon uses fork to send the process into the
background, any threading primitives are unsafe to re-use after the call.
Implementations of pthread recursive mutexes are highly likely to store the
thread identifier of the thread that previously obtained the mutex.  If
the mutex was locked prior to the fork, a subsequent unlock operation will
potentially fail as the thread identifier is no longer valid.  Since the
mutex is still locked, all subsequent attempts to grab the mutex by other
threads will block.

This behavior exhibited itself most often when DEBUG_THREADS was enabled, as
this compile time option surrounds the mutexes in Asterisk with another
recursive mutex that protects the storage of thread related information.  This
made it much more likely that a recursive mutex would be obtained prior to
daemon and unlocked after the call.

This patch does the following:
a) It backports a patch from Asterisk 11 that prevents the spawning of the
   localtime monitoring thread.  This thread is now spawned after Asterisk has
   fully booted.
b) It re-orders the startup sequence to call daemon earlier during Asterisk
   startup.  This limits the potential of threading primitives being accessed
   by initialization calls before daemon is called.
c) It removes calls to ast_verbose/ast_log/etc. prior to daemon being called.
   Developers should send error messages directly to stderr prior to daemon,
   as calls to ast_log may access recursive mutexes that store thread related
   information.
d) It reorganizes when thread local storage is created for storing lock
   information during the creation of threads.  Prior to this patch, the
   read/write lock protecting the list of threads in ast_register_thread would
   utilize the lock in the thread local storage prior to it being initialized;
   this patch prevents that.

On a very related note, this patch will *greatly* improve the stability of the
Asterisk Test Suite.

Richard Mudgett 1bba4b00b2 Add MALLOC_DEBUG enhancements.
* Makes malloc() behave like calloc().  It will return a memory block
filled with 0x55.  A nonzero value.

* Makes free() fill the released memory block and boundary fence's with
0xdeaddead.  Any pointer use after free is going to have a pointer
pointing to 0xdeaddead.  The 0xdeaddead pointer is usually an invalid
memory address so a crash is expected.

* Puts the freed memory block into a circular array so it is not reused
immediately.

* When the circular array rotates out a memory block to the heap it checks
that the memory has not been altered from 0xdeaddead.

* Made the astmm_log message wording better.

* Made crash if the DO_CRASH menuselect option is enabled and something is
found.

* Fixed a potential alignment issue on 64 bit systems.
struct ast_region.data[] should now be aligned correctly for all
platforms.

* Extracted region_check_fences() from __ast_free_region() and
handle_memory_show().

* Updated handle_memory_show() CLI usage help.

  Fix misuses of timeouts throughout the code.
  
  Prior to this change, a common method for determining if a timeout
  was reached was to call a function such as ast_waitfor_n() and inspect
  the out parameter that told how many milliseconds were left, then use
  that as the input to ast_waitfor_n() on the next go-around.
  
  The problem with this is that in some cases, submillisecond timeouts
  can occur, resulting in the out parameter not decreasing any. When this
  happens thousands of times, the result is that the timeout takes much
  longer than intended to be reached. As an example, I had a situation where
  a 3 second timeout took multiple days to finally end since most wakeups
  from ast_waitfor_n() were under a millisecond.
  
  This patch seeks to fix this pattern throughout the code. Now we log the
  time when an operation began and find the difference in wall clock time
  between now and when the event started. This means that sub-millisecond timeouts
  now cannot play havoc when trying to determine if something has timed out.
  
  Part of this fix also includes changing the function ast_waitfor() so that it
  is possible for it to return less than zero when a negative timeout is given
  to it. This makes it actually possible to detect errors in ast_waitfor() when
  there is no timeout.

Matthew Jordan f0cd27e027 Refactor ast_timer_ack to return an error and handle the error in timer users
Currently, if an acknowledgement of a timer fails Asterisk will not realize
that a serious error occurred and will continue attempting to use the timer's
file descriptor.  This can lead to situations where errors stream to the
CLI/log file.  This consumes significant resources, masks the actual problem
that occurred (whatever caused the timer to fail in the first place), and
can leave channels in odd states.

This patch propagates the errors in the timing resource modules up through
the timer core, and makes users of these timers handle acknowledgement
failures.  It also adds some defensive coding around the use of timers
to prevent using bad file descriptors in off nominal code paths.

Note that the patch created by the issue reporter was modified slightly for
this commit and backported to 1.8, as it was originally written for
Asterisk 10.

Matthew Jordan 769d9aa259 Don't attempt to purge sessions when no sessions exist
Manager's tcp/tls objects have a periodic function that purge old manager
sessions periodically.  During shutdown, the underlying container holding
those sessions can be disposed of and set to NULL before the tcp/tls periodic
function is stopped.  If the periodic function fires, it will attempt to
iterate over a NULL container.

This patch checks for whether or not the sessions container exists before
attempting to purge sessions out of it.  If the sessions container is NULL,
we simply return.

Note that this error was also caught by the Asterisk Test Suite.

Matthew Jordan 69777a9376 Prevent multiple CDR batches from conflicting when scheduling the CDR write
The Asterisk Test Suite caught an error condition where a scheduled CDR batch
write can be deleted twice if two channels attempt to post their CDRs at the
same time.  The batch CDR mutex is locked while the CDRs are appended to the
current batch list; however, it is unlocked prior to actually scheduling the
CDR write.  As such, two threads can attempt to remove the currently scheduled
batch write at the same time, resulting in an assertion error.

This patch extends the time that the mutex is locked to encompass actually
scheduling the write.  This prevents two threads from unscheduling the
currently scheduled write at the same time.

Mark Michelson 94c0fa9098 Fix some potential misuses of ast_str in the code.
Passing an ast_str pointer by value that then calls
ast_str_set(), ast_str_set_va(), ast_str_append(), or
ast_str_append_va() can result in the pointer originally
passed by value being invalidated if the ast_str had
to be reallocated.

This fixes places in the code that do this. Only the
example in ccss.c could result in pointer invalidation
though since the other cases use a stack-allocated ast_str
and cannot be reallocated.

I've also updated the doxygen in strings.h to include
notes about potential misuse of the functions mentioned
previously.

Mark Michelson ccf01fbfdc Do not use a FILE handle when doing SIP TCP reads.
This is used to solve an issue where a poll on a file
descriptor does not necessarily correspond to the readiness
of a FILE handle to be read.

This change makes it so that for TCP connections, we do a
recv() on the file descriptor instead.

Because TCP does not guarantee that an entire message or even
just one single message will arrive during a read, a loop has
been introduced to ensure that we only attempt to handle a
single message at a time. The tcptls_session_instance structure
has also had an overflow buffer added to it so that if more
than one TCP message arrives in one go, there is a place to
throw the excess.

Huge thanks goes out to Walter Doekes for doing extensive review
on this change and finding edge cases where code could fail.

time) and immediately hung up on (indicating a billsec of 0).  Since
a billing time of '0' can either mean that the call immediately ended
or that the CDR was improperly answered, we have to use additional information
to know whether or not we can trust the CDR billsec value.  Prior to this
patch, we looked to see if we had a valid answer time.  If we did, and
billsec was zero, we used the current time to calculate what billsec value
we could from the CDR being written.  If batch mode is enabled, this will
incorrectly report a billsec value being much greater than the actual
duration of the call.

Instead of relying on the presence of an answer time to know whether or not
we can re-calculate the billsec for the CDR, we now also use the presence
of the CDR's end time to know if we need to re-calculate or whether we can
trust the billsec value that we have.  This prevents erroneous jumps in the
billsec value, while still making sure that in the worst case, some billing
time will be calculated.

Mark Michelson b5f231501b Don't make chan_sip export global symbols.
During testing, it was discovered that having chan_sip
export global symbols was problematic.

The biggest problem was that load order was affected.
Trying to use realtime could be problematic since in
all likelihood the necessary realtime driver(s) would
not be loaded before chan_sip.

In addition, it was found that it was impossible to
use the Digium Phone Module for Asterisk since it
must be loaded before chan_sip since it must hook
into chan_sip's configuration parsing.

The solution is to use a virtual table in the same
manner that other modules in Asterisk do, like
app_voicemail.

When using the channel technology agnostic application/AMI command MessageSend,
the "From" field is technically optional for the SIP channel driver.  However,
if being sent by the XMPP resource module (either res_xmpp or res_jabber), the
"From" field is necessary, and must correspond to a defined account.  This
patch updates the documentation for this application/AMI command to reflect
this.

  Improve AMI long line error handling
  
  In AMI's parser, when it receives a long line (> 1024 characters), it discards
  that line, but continues to process the message normally.
  
  Typically, this is not a problem because a) who has lines that long and b)
  usually a discarded line results in an invalid message. But if that line is
  specifying an optional field, then the message will be processed, you get a
  'Response: Success', but things don't work the way you expected them to.
  
  This patch changes the behavior when a line-too-long parse error occurs.
  
  * Changes the log message to avoid way-too-long (and truncated anyways) log
    messages
  * Adds a 'parsing' status flag to Response: Success
  * Sets parsing = MESSAGE_LINE_TOO_LONG if, well, a line is too long
  * Responds with an appropriate error if parsing != MESSAGE_OKAY

David M. Lee 2659db6d61 Fix DBDelTree error codes for AMI, CLI and AGI
The AMI DBDelTree command will return Success/Key tree deleted successfully even
if the given key does not exist. The CLI command 'database deltree' had a
similar problem, but was saved because it actually responded with '0 database
entries removed'. AGI had a slightly different error, where it would return
success if the database was unavailable.

This came from confusion about the ast_db_deltree retval, which is -1 in the
event of a database error, or number of entries deleted (including 0 for
deleting nothing).

* Changed some poorly named res variables to num_deleted
* Specified specific errors when calling ast_db_deltree (database unavailable
  vs. entry not found vs. success)
* Fixed similar bug in AGI database deltree, where 'Database unavailable'
  results in successful result

Various countries have different specifications for the maximum power level differences
between the DTMF low group and high group of frequencies.

Power level difference between frequencies for different Administrations/RPOAs
 NTT        = Max. 5 dB
 AT&T       = 4dB(reverse) to 8dB(normal)
 Danish     = Max. 6 dB
 Australian = Max. 10 dB
 Brazilian  = Max. 9 dB
 ETSI       = Max. 6 dB from ETSI ES 201 235-3 V1.3.1 (2006-03)

Now allow 4 variables to be individually configured in dsp.conf, with reasonable min/max of 2dB to 20dB.
Default is AT&T specifications

Add's the following variables to dsp.conf
;dtmf_normal_twist=6.31 
;dtmf_reverse_twist=2.51 
;relax_dtmf_normal_twist=6.31

Sean Bright 1449b2cad0 app_queue: Support persisting and loading of long member lists.
Greenlight in #asterisk brought up that he was receiving an error message "Could
not create persistent member string, out of space" when running app_queue in
Asterisk 10.  dump_queue_members() made an assumption that 8K would be enough to
store the generated string, but with queues that have large member lists this is
not always the case.  This patch removes the limitation and uses ast_str instead
of a fixed sized buffer.

The complicating factor comes from the fact that ast_db_get requires a buffer
and buffer size argument, which doesn't let us pull back more than what we pass
in, so I introduced a new ast_db_get_allocated() which returns an ast_strdup()'d
copy of the value from astdb.

As an aside, I did some testing on the maximum size of data that we can store in
the BDB library we distribute and was able to store a 10MB string and retrieve
it with no problems, so I feel this is a safe patch.

Joshua Colp 302cc28472 loader: Ensure dependent modules are properly initialized.
If an Asterisk module specifies a dependency in ast_module_info.nonoptreq, it
is possible for Asterisk to skip calling the modules's .load function.
Asterisk was loading and linking the module via load_dynamic_module() but was
not adding the module to the resource_heap. Therefore the module was not
initialized based on it's priority along with the other modules in the heap.

Now use load_resource() instead of load_dynamic_module() for non-optional
requirement. This will add the module to the resource_heap so the module can
be properly initialized in the correct order.

This is required if there are any module global data structures initialized in
the .load() callback for the module on platforms which do not support weak
references.

Richard Mudgett 7e9bdcc3e0 Named call pickup groups. Fixes, missing functionality, and improvements.
* ASTERISK-20383
Missing named call pickup group features:

CHANNEL(callgroup) - Need CHANNEL(namedcallgroup)
CHANNEL(pickupgroup) - Need CHANNEL(namedpickupgroup)
Pickup() - Needs to also select from named pickup groups.

* ASTERISK-20384
Using the pickupexten, the pickup channel selection could fail even though
there was a call it could have picked up.  In a call pickup race when
there are multiple calls to pickup and two extensions try to pickup a
call, it is conceivable that the loser will not pick up any call even
though it could have picked up the next oldest matching call.

Regression because of the named call pickup group feature.

* See ASTERISK-20386 for the implementation improvements.  These are the
changes in channel.c and channel.h.

* Fixed some locking issues in CHANNEL().

Matthew Jordan 9e396da730 Resolve memory leaks in TLS initialization and TLS client connections
This patch resolves two sources of memory leaks when using TLS in Asterisk:
1) It removes improper initialization (and multiple re-initializations) of
   portions of the SSL library.  Asterisk calls SSL_library_init and
   SSL_load_error_strings during SSL initialization; collectively this
   obviates the need for calling any of the following during initialization
   or client connection handling:
   * ERR_load_crypto_strings (handled by SSL_load_error_strings)
   * OpenSSL_add_all_algorithms (synonym for SSL_library_init)
   * SSLeay_add_ssl_algorithms (synonym for SSL_library_init)
2) Failure to completely clean up all memory allocated by Asterisk and by
   the SSL library for TLS clients.  This included not freeing the SSL_CTX
   object in the SIP channel driver, as well as not clearing the error
   stack when the TLS client exited.

Note that these memory leaks were found by Thomas Arimont, and this patch
was essentially written by him with some minor tweaks.

waited. This is a problem if it consistently waits less than 1ms. The timeout
will never be decremented, and we wait... FOREVER!

This patch makes ast_waitfordigit_full manage the timeout itself. It maintains
the previously undocumented behavior that negative timeouts wait forever.

David M. Lee 14947e93cc Fixed r372696 when configured --disable-asteriskssl; properly install libasteriskssl.dylib on OS X.
I didn't realize that libasteriskssl.c was still compiled, even when you
disable asteriskssl; it simple gets statically linked into asterisk.

Mark Michelson 46b730b070 Fix inability to shutdown gracefully due to an unending channel reference.
message.c makes use of a special message queue channel that exists
in thread storage. This channel never goes away due to the fact that
the taskprocessor used by message.c does not get shut down, meaning
that it never ends the thread that stores the channel.

This patch fixes the problem by shutting down the taskprocessor when
Asterisk is shut down. In addition, the thread storage has a destructor
that will release the channel reference when the taskprocessor is destroyed.
