<pre class="bz_comment_text">Hi,
<span class="quote">> Version Details </span >
DPDK Version : 19.11.10
Architecture : s390x (Big-Endian)
Linux OS Kernel : 5.4.0-128-generic
Ubuntu Version : 18.04.6 LTS
<span class="quote">> Issue:</span >
We are using ACL Library apis as part of DPDK application. As part of our
application we are trying to set following simple egress rule using function
rte_acl_add_rules():
src: 0.0.0.0/0
dst: 0.0.0.0/0
src port: 0:65535
dst port: 1:65535
protocol/mask: 6/255
category mask: 1 priority: 1 userdata: 536870912 (0x20000000)
The setting and building of rules are success.
We are then passing tcp packet to check if the same is getting matched. When
rte_acl_classify() is invoked with tcp(0x6) data as argument, we are getting
result as 0 instead of 0x2. So, a mismatch on the protocol rule is observed and
therefore packet is dropped on egress.
<span class="quote">> Additional Query:</span >
Also, Is it possible to tell what is and how wildness is calculated for each
field in a rule?
Can you provide some insights with the issue and query ?
Also, I am new to this DPDK bugzilla, is it possible to share any
forum/community where we can ask code-related queries (about the terms used in
code) for the purpose of debugging ?
Regards,
Utsav
