Important: A significant flaw is present in June BIND releases 9.16.17 and 9.17.14
Dear BIND users: Yesterday, 16 June 2021, we released monthly maintenance snapshot releases of our currently supported release branches of BIND. Specifically, we released BIND 9.11.33, 9.16.17, and 9.17.14 There's no way to say this that isn't embarrassing, but only after the release was an error in a recently optimized routine discovered by a user -- an error that will definitely cause operational problems for almost all server operators who upgrade to either of these affected versions: - BIND 9.16.17 - BIND 9.17.14 BIND 9.11.33 is NOT affected. If you have not yet updated to the 16 June releases, we ask that you hold off on any plans to install 9.16.17 or 9.17.14 until replacement releases can be prepared and tested. The specific issue in question is being tracked in our issue tracker: https://gitlab.isc.org/isc-projects/bind9/-/issues/2779 and more information about our plans for issuing replacement releases will be provided later; at the moment our priority is getting the news to parties as quickly as possible so that those who have not already adopted the new releases can postpone until corrected versions are available.

Limit actions on control channel?
I see I can define (using the 'controls' statement) a 'read-only' inet channel. I suspect I could define a couple of channels on the same address if I put them on different ports. Is there a way to define a single 'read-write' channel, and then limit certain keys to read-only access on it? Here's the scenario: I'd like to have a single control channel listening (on port 953, for example). I'd like to say the key named "foo" can do lots of things, but the key named "bar" can only submit a "status" message. This would let our monitoring application ask for "status" without also letting it ask for "reload" or "flushname". -- -- Do things because you should, not just because you can.

BIND does not start multiple processes. There's only ever one process, called "named". BIND starts multiple threads. You can see these by using the "top" command in Linux, and then pressing "H" to see threads rather than processes. You should see 4 worker threads, as well as some other threads.
