Nick Mathewson	f9f450d688	Also raise the check for 0 circuit ID in created cell. ... And add a comment about why conditions that would cause us to drop a cell should get checked before actions that would cause us to send a destroy cell. Spotted by 'cypherpunks'. And note that these issues have been present since 0.0.8pre1 (commit 0da256ef), where we added a "shutting down" state, and started responding to all create cells with DESTROY when shutting down.	2014-06-13 08:39:39 -04:00
Nick Mathewson	af53e4bd1c	Move circuit-id-in-use check for CREATE cells to before all other checks ... This means that we never send a DESTROY cell in response to an attempt to CREATE an existing circuit. Fixes bug 12191.	2014-06-10 22:41:13 -04:00
