These cases are usually a sign of - redundant checking, or dubious arithmetic. Found by Georg Koppen using - the "STACK" tool from Wang, Zeldovich, Kaashoek, and - Solar-Lezama. Fixes bug 24423; bugfix on various Tor versions. - - o Minor bugfixes (hidden service v3): - - Fix a race between the circuit close and free where the service would - launch a new intro circuit after the close, and then fail to register it - before the free of the previously closed circuit. This was making the - service unable to find the established intro circuit and thus not upload - its descriptor. It can make a service unavailable for up to 24 hours. - Fixes bug 23603; bugfix on 0.3.2.1-alpha. - - o Minor bugfixes (scheduler): - - Properly set the scheduler state of an unopened channel in the KIST - scheduler main loop.
