| | |/ | | | | | | | | | builders. The n variable does not add the size of the payload (payload_s) for proper allocation of the buffer when payload is not NULL and payload_s is greater than 0. This results in a memcpy buffer overflow error when libnet_pblock_append is called exiting the program.

| | | | | | | | | | | | | | | | | | | | I think this is because of differing versions of Ubuntu; the one on the build server uses dnet.h still.

| | | | | | | | | | | | | | | | | | | | | Coverity noticed that stack garbage was being passed instead of a valid value, its just that the value isn't used, and incluing l->total_size is wrong when the pblock is being updated (though it will work on pblock creation).
