From 5cdf4d78d15b127d0f4a7a09e4700d7df16dda19 Mon Sep 17 00:00:00 2001 From: Andrea Claudi Date: Mon, 29 Apr 2019 20:08:08 +0200 Subject: [PATCH] lnstat_util: Simplify alloc_and_open() a bit Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1465646 Upstream Status: iproute2.git commit bc27878d21909 commit bc27878d21909b110dd21eea0c3505d023f29dc2 Author: Phil Sutter Date: Thu Aug 24 11:51:48 2017 +0200 lnstat_util: Simplify alloc_and_open() a bit Relying upon callers and using unsafe strcpy() is probably not the best idea. Aside from that, using snprintf() allows to format the string for lf->path in one go.
