Witold Kręcicki 14a852b86d fixup! Make client resolver tasks pooled and CPU-bound 2020-02-07 11:21:49 +01:00
Witold Kręcicki 30675428d8 Fix a race in isc_socket destruction. 
There was a very slim chance of a race between isc_socket_detach and
process_fd: isc_socket_detach decrements references to 0, and before it
calls destroy gets preempted. Second thread calls process_fd, increments
socket references temporarily to 1, and then gets preempted, first thread
then hits assertion in destroy() as the reference counter is now 1 and
not 0.

Witold Kręcicki 627bf906ab test: don't use DISPATCHATTR_EXCLUSIVE, less random but waaay less sockets used 2020-02-07 08:42:02 +01:00

Witold Kręcicki e80ac06ed4 Don't update LRU if the node was recently used. 
Updating LRU requires write-locking the node, which causes contention.
Update LRU only if time difference is large enough.

Witold Kręcicki 91d5c3313c Bucketed statistics. 
Even though statistics are lockless they still use atomics which
might cause contention. Split stats counters into buckets, sharded
by an artificial thread identifier, to increase throughput.

Witold Kręcicki 85a3cc6ffa Disable OpenSSL siphash. 
Creation of EVP_MD_CTX and EVP_PKEY is quite expensive, until
we fix the code to reuse the context and key we'll use our own
implementation of siphash.

Witold Kręcicki 666b0f7564 Make client resolver tasks pooled and CPU-bound 2020-02-07 08:40:25 +01:00
Witold Kręcicki bcb55107ac Make isc_task_pause/isc_task_unpause thread safe. 
isc_task_pause/unpause were inherently thread-unsafe - a task
could be paused only once by one thread, if the task was running
while we paused it it led to races. Fix it by making sure that
the task will pause if requested to, and by using a 'pause reference
counter' to count task pause requests - a task will be unpaused
iff all threads unpause it.

Don't remove from queue when pausing task - we lock the queue lock
(expensive), while it's unlikely that the task will be running -
and we'll remove it anyway in dispatcher
