test_pktmbuf_read_from_offset tests for incorrect overflow behaviour of rte_pktmbuf_read

Bug ID: 1724
Summary: test_pktmbuf_read_from_offset tests for incorrect
overflow behaviour of rte_pktmbuf_read
Product: DPDK
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: minor
Priority: Normal
Component: core
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Test function test_pktmbuf_read_from_offset as one of its checks surprisingly verifies that the following call succeeds even though rte_pktmbuf_read never guarantees this behaviour in its documentation:
rte_pktmbuf_read(m, hdr_len, UINT_MAX, NULL);
The reason this call succeeds is due to 32-bit unsigned integer overflow, but it is unlikely that this behaviour is intentional and needs testing. It is very likely instead that the check condition was reversed by mistake. Other similar calls that follow are being correctly verified as failing. And, there were no checks of valid offset and excessive length combinations that would cause the call to fail.
