Bug ID: 307
Summary: ACL (librte_acl) field of type RANGE and size U32 is
not working properly
Product: DPDK
Version: 18.11
Hardware: All
OS: All
Status: CONFIRMED
Severity: normal
Priority: Normal
Component: other
Assignee: dev@dpdk.org

acl-test for single field match - can be compiled like any dpdk/example
Hi,
Such ACL field doesn't seem to work properly
~~~
{
.type = RTE_ACL_FIELD_TYPE_RANGE,
.size = sizeof(uint32_t),
...
}
~~~
I found same complain here
https://mails.dpdk.org/archives/users/2017-June/002096.html (by Doohwan Lee)
with no resolution.
Also all DPDK ACL test/examples RTE_ACL_FIELD_TYPE_RANGE fields are with
uint16_t and never with uint32_t
Attached is a small acl-test app
It sets a single ACL field (though there are few in the acl_fields array all
the rest are don't-care)
And matches a data argument (no need for traffic/packets)
usage:
~~~
./acl-test [EAL options] -- [app options]
app options:
--size=16|32
[--type=RANGE --min=<min> --max=<max>]
[--type=BITMASK --value=<value> --bitmask=<bitmask>]
--data=<data>
example:
./acl-test --no-huge -c 1 -- --size=32 --type=RANGE --min=100 --max=200
--data=150
~~~
Output example for RANGE U16
~~~

Bad output example for RANGE U32 (same test just size change)
