To: dev; +Cc: Bruce Richardson
For files that already have rte_string_fns.h included in them, we can
do a straight replacement of snprintf(..."%s",...) with strlcpy. The
changes in this patch were auto-generated via command:
spatch --sp-file devtools/cocci/strlcpy-with-header.cocci --dir . --in-place

From: Bruce Richardson @ 2019-04-03 14:45 UTC (permalink / raw)
To: dev; +Cc: Bruce Richardson
Do a global replace of snprintf(..."%s",...) with strlcpy, adding in the
rte_string_fns.h header if needed. The function changes in this patch were
auto-generated via command:
spatch --sp-file devtools/cocci/strlcpy.cocci --dir . --in-place
and then the files edited using awk to add in the missing header:
gawk -i inplace '/include <rte_/ && ! seen { \
print "#include <rte_string_fns.h>"; seen=1} {print}'
