1 o Minor bugfixes (circuit, hidden service)
2 - When closing a circuit, the reason for doing so was assigned from an int
3 value to a uint16_t which is quite a problem for negative values that are
4 our internal reasons (ex: END_CIRC_REASON_IP_NOW_REDUNDANT). On the HS
5 side, this was causing introduction points to be flagged as unusable
6 because the reason wasn't the right one due to the bad conversion.
7 Partially fixes bug 21056 and fixes bug 20307; Bugfix on 0.2.8.1-alpha.
