53015aa4cb Round robin for backends. 
Several threads calling backend_select might reset current_backend to a
different place, there are two options to deal with that:
- just let the last rotation win (the current approach)
- detect whether first == current_backend and only replace then

Not sure which one is more useful, going with the simpler.

e65cd38787 Round-robin for upstream connections 2020-11-17 17:55:46 +00:00

58a880bc7b Convert backend and upstream management to use CIRCLEQ. 
This alone doesn't make the server do a round robin.

643194e79e Revert connection/operation mutex order. 
There was still a race where the connection could be freed as the
operation was still being used.

8eb7f3fbca Stop the read callback on a dead connection. 
The connection might be ready to read (close) but if we can't destroy it
yet, we don't want the callback to trigger all the time or process new
data.

028f28690f On a failed bind, stop the callback from firing again 
Not a problem but causes a slew of calls to upstream_bind_cb that will
all fail in the same way.

6abfd60078 ITS#9370 revert previous commit, alternate fix 
Just skip normalization if there's no equality rule. We accept

Howard Chu
a08a2db406 ITS#9370 check for equality rule on old_rdn 
We should probably just check in dnNormalize instead, and catch
this everywhere DNs are received. It might make us reject some
DNs that are already in use, though (e.g. received from other
directory servers that don't do schema checking).
