From 71bb05454c97cc18e3c95127b54385c52e4c57c2 Mon Sep 17 00:00:00 2001 From: Andrew Yourtchenko Date: Wed, 16 Aug 2017 12:06:15 +0200 Subject: acl-plugin: time out the sessions created by main thread too (VPP-948) In multithread setup the main thread may send packets, which may pass through the node with permit+reflect action. This creates the connection in lists for thread0, however in multithread there are no interupt handlers there. Ensure we are not spending too much time spinning in a tight cycle by suspending the main cleaner thread until the current iteration of interrupts is processed.
