strncpy may leave the destination buffer not NULL terminated so use
snprintf instead.

Coverity issue: 362975
Fixes: 339b88c6a91f ("net/af_xdp: support multi-queue")

What do you think using 'strlcpy'?

Or even better, rte_strscpy()

I think this is largely a matter of preference, and unless there is a good
reason not to, I tend towards strlcpy as the older and more common (till
now) interface. The main thing is just to use a function that will
guarantee dest is null-terminated here, and both strlcpy and strscpy meet
that criteria.

I'd also add that strlcpy is more likely to be recognised by tools like
coverity, compared to rte_strscpy which is DPDK-specific.

+1 to 'strlcpy'

Using strlcpy will be more recognized by static analyzer indeed.

But strscpy API is better:

* It helps checking string truncation by making it easier:

  if (strlcpy(dst, src, dstsize) >= dstsize)
        /* Dev + reviewer needs to think about using >= and not >, dstsize is
         * repeated so either dst is an array or it needs a dedicated variable.
         * Deal with truncation.
         */

  if (rte_strscpy(dst, src, dstsize) < 0)
        /* deal with truncation. */

* It is safer when dealing with unknown data source. strlcpy will always
  read all of src, because the API (uselessly) defines the return value
  to strlen(src).

Having yet another string copy function is contentious, but we can avoid
using worse API to please tools.

And detecting string truncation *is* helpful. String are used as IDs in
DPDK for some objects. Using strlcpy / snprintf at least protects from
buffer overflow, which is a bare minimum. A good implementation would
also warn the user about a config error / memory corruption happening
sooner.

In any case, sure to fix a sanity check strlcpy / snprintf will work.

Yes.

My main issue with strscpy right now is that it's got to be a DPDK-specific
function, since AFAIK it's defined in no standard C library, just in the
Linux kernel. If we get strscpy added to e.g. glibc, then we can see about
starting to use it - letting meson do the work of detect if it's present
and allowing us to define a fallback only in case it's not (i.e. as is done
with strlcpy).

I also think 'strscpy' is better API, and we had similar discussion before [1] 
and the decision was to prefer 'strlcpy'.
