Date: Wed, 09 May 2018 12:43:52 +0000 [thread overview]
Message-ID: <bug-44-3@http.dpdk.org/tracker/> (raw)
https://dpdk.org/tracker/show_bug.cgi?id=44
Bug ID: 44
Summary: examples/l2fwd-crypto : Wrong data length in case of
AEAD ciphers
Product: DPDK
Version: 18.05
Hardware: All
OS: All
Status: CONFIRMED
Severity: normal
Priority: Normal
Component: examples
Assignee: dev@dpdk.org
Reporter: ankur.dwivedi@cavium.com
Target Milestone: ---
In l2fwd-crypto application, file main.c , the digest length is not getting
decremented for AEAD ciphers.
Line 410:
if (cparams->do_hash && cparams->hash_verify)
data_len -= cparams->digest_length;
I think this results in wrong values assignment in line 517
op->sym->aead.data.length = data_len;
and wrong digest data pointer assignment in line 524
op->sym->aead.digest.data = rte_pktmbuf_mtod(m,
uint8_t *) + ipdata_offset + data_len;
