This commit resolves three null pointer dereferences mentioned by Bogdanisar. Comments about changes: 1) onion.c Add return statement if promotion to https had failed and set member variable only in !=NULL case. 2) Here, I'm unsure if my change is correct. I assume that the NULL-check is using the wrong variable! First of all, a check of the bl variable is missing. This indicates that (bl == NULL) would be the correct check. Moreover, the redis session probably should be deleted if the data dict is empty, too. Thus, I changed the line to if (onion_dict_count(data) == 0 || bl == NULL) Other variants would be if (bl == NULL) if (data == NULL || bl == NULL ) 3) poller.c: If added a NULL check because poller->head is initialized with NULL in onion_poller_new.
