From bd513cd08f10cbe28856f99ae951e86e86803861 Mon Sep 17 00:00:00 2001 From: Mauricio Vasquez B Date: Thu, 18 Oct 2018 15:16:30 +0200 Subject: bpf: add MAP_LOOKUP_AND_DELETE_ELEM syscall The previous patch implemented a bpf queue/stack maps that provided the peek/pop/push functions. There is not a direct relationship between those functions and the current maps syscalls, hence a new MAP_LOOKUP_AND_DELETE_ELEM syscall is added, this is mapped to the pop operation in the queue/stack maps and it is still to implement in other kind of maps.
