Message-Id: <20170817170932.24659-6-phil@nwl.cc> Date: Thu, 17 Aug 2017 19:09:30 +0200 From: Phil Sutter <phil@....cc> To: Stephen Hemminger <stephen@...workplumber.org> Cc: netdev@...r.kernel.org Subject: [iproute PATCH v2 5/7] 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.
