   <pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Through a static analysis tool, a large number of errors were found that dealt with using potential negative return values in harmful ways.  The following is a summary of the changes for the various affected files:

* app_voicemail
  - a negative result from lseek is later passed into mmap as the size of the memory map
  - a negative result from read closes the various file descriptors and unlinks the output file, but the next check against the return value only checks to see if its non-zero
* chan_agent - ast_channel_unlock returns a negative value if the item passed to it is NULL or an invalid ao2 object.  strerror cannot accept a negative value.
* chan_dahdi - if dahdi_get_index returns a negative value, we index directly into an array
* format_* - various errors not checking return values of ftello and fseek, and passing the results into functions that expect non-negative values
* func_env - various places where the result of ftello was directly used as input to functions that expect non-negative values
* asterisk
  - the request to read returns a negative value.  This causes us to enter into the retry logic.  If we attempt to reconnect and succeed, we would normally proceed in the for(;;) loop and attempt to index into buf using the negative return value from read.  Instead, if we do reconnect, we immediately return to the beginning of the for(;;) loop and attempt a new read.
  - similar situation - if a read fails, don&#39;t attempt to index into a buffer using the return value
* frame - if we can&#39;t determine a preferred codec using the provided values, don&#39;t attempt to use an index value that never got set
* manager 
  - various failures of mkstemp, lseek were not checked for and could be provided to methods that don&#39;t handle negative numbers
  - passing a negative result from lseek into mmap as the size of the memory map
* translate - powerof can return a negative result if no bits are set, which would then be used as an index into an array
* res_agi - if read returns an error, we treated it as if bytes were read from the pipe
* res_musiconhold - if we fail to spawn spawn_mp3 returns a negative number, we wait a bit and attempt again later.  However, the return &#39;file descriptor&#39; srcfd is later passed into read.
* res_rtp_asterisk - ast_rtp_codecs_payload_code can return a negative value if no codecs are found that match between instance1 and the specified payload.  If that&#39;s the case, the bridge should be broken, as there are no compatible formats between the two different endpoints (and we shouldn&#39;t index into an array using the return value)</pre>
