Hi,
It seems that with DPDK 16.07, rte_zmalloc() and related functions no
longer return zeroed memory reliably on FreeBSD.
I notice that?commit b78c9175118f7d61022ddc5c62ce54a1bd73cea5 ("mem: do
not zero out memory on zmalloc") removed the explicit memset() that used
to ensure the buffer was zeroed; its log message says:
"Zeroing out memory on rte_zmalloc_socket is not required anymore since
all?allocated memory is already zeroed."
However, I don't see how this is guaranteed (at least for FreeBSD), and
it is not true in?practice. ?I've attached a minimized reproducer program -
running it twice in a row fails reliably for me.
Is there a missing step in FreeBSD, or is it a more general problem for
other platforms?
Thanks,
-- Daniel
