From 8bea589cfe0fca1a6f560e16ca66a4cf199041a2 Mon Sep 17 00:00:00 2001 From: Damjan Marion Date: Mon, 4 Apr 2022 22:40:45 +0200 Subject: vppinfra: make _vec_len() read-only Use of _vec_len() to set vector length breaks address sanitizer. Users should use vec_set_len(), vec_inc_len(), vec_dec_len () instead.
