P.S., In Coverity there are a number of "Out-of-bounds access (OVERRUN)"
defects that relate to rte_memcpy() or one of the wrappers around it. They look
like this:
CID 362728 (#1 of 1): Out-of-bounds access (OVERRUN)
11. overrun-buffer-val: Overrunning array tdata->auth_tag.data of 16 bytes
by
passing it to a function which accesses it at byte offset 160.
8182 rte_memcpy(sym_op->aead.digest.data,
tdata->auth_tag.data,
8183 tdata->auth_tag.len);
8184 debug_hexdump(stdout, "digest:",
8185 sym_op->aead.digest.data,
8186 tdata->auth_tag.len);
8187 }
As far as we can tell these are false positives since there are a number of
different size handling statements in rte_memcpy() and an issue like this would
result in an immediate error under any sort of load.
In this case you can edit the defect online and change the defect
"Classification" to "False Positive" and change the "Action" to "Ignore".
If anyone disagrees and thinks that this is a real issue, let me know.

Subject: Open Coverity defects in DPDK
Folks,
If your email is on the "To" list then you have an open defect in the DPDK
Coverity database. Due to an issue with an automated emailer you may not have
received an email notifying you about this. We will try to send them again.
In the meantime you can see the defects against your email in the list below.
If you spot any email addresses that are no longer valid please let me and Sean
know.
You can review the defects online at:
