Changes
-------

Committed in revision 423276


Repository: Asterisk


Description
-------

If you call ast_category_insert with a match category that doesn't exist, the list traverse runs out of 'next' categories and you get a SEGV.  This patch adds check for the end-of-list condition and changes the signature to return an int for success/failure indication instead of a void.

The only consumer of this function is manager and it was also changed to use the return value.

Testing
-------

Tested with AMI UpdateConfig/newcat to make sure the proper value is returned in both positive and negative cases.


Thanks,

George Joseph
