From: Harry van Haaren Date: Wed, 11 Mar 2020 14:39:27 +0000 (+0000) Subject: service: fix crash on exit X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=33666b448f15687ceaf61eac405d945391fe7066;p=dpdk.git service: fix crash on exit This commit releases all service cores from their role, returning them to ROLE_RTE on rte_service_finalize(). This fixes an issue relating to the service cores causing a race-condition on rte_eal_cleanup(), where the service core could still be executing while the main thread has already free-d the service memory, leading to a segfault.
