I think it is NOT correct. 
It SEEMS unsafe to use strncpy() even if it terminated 
string correctly.

So, I'd suggest to replace

    strlcpy(dst, src, len);

with 

 1)   strlcpy0(dst, src, len);

where strlcpy0() is provided in my previous mail,
or with

 2)   memset(dst, 0, len);
      strncpy(dst, src, len);

(or say, strncpy0())
or, with

 3)   if (len)
         strncpy(dst, src, len - 1);
      dst[len] = 0;

(or, say, strncpy0()).
