Subject: [dpdk-dev] [PATCH] memzone: Check socket_id value when creating memzone.
Date: Thu, 11 May 2017 23:03:43 -0700 [thread overview]
Message-ID: <1494569023-7564-1-git-send-email-nic@opencloud.tech> (raw)
If the socket_id is invalid (e.g. -2, -3), the
memzone_reserve_aligned_thread_unsafe should return the
EINVAL and not ENOMEM. To avoid it, we should check the
socket_id before calling malloc_heap_alloc.
