Build fails: strncpy’ output truncated before terminating nul copying as many bytes from a string as its length #4

Open Rot127 opened 3 years ago

Build fails for newer gcc versions (I think beginning from ver. 8) with: strncpy’ output truncated before terminating nul copying as many bytes from a string as its length [-Werror=stringop-truncation] for the files:

gre2tun.c
tun2gre.c
tundev.c

Workaround: Replace strncpy with memcpy.

Though this doesn't solve the truncation problem here!
