Bug ID: 501
Summary: igb: segfault in rte_eth_tx_done_cleanup() when using
advanced descriptors
Product: DPDK
Version: 19.05
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: major
Priority: Normal
Component: ethdev
Assignee: dev@dpdk.org
Reporter: pawel...@gmail.com
Target Milestone: ---
For advanced descriptors the eth_igb_xmit_pkts() function is using one
additional TX ring descriptor entry but is not setting txe->mbuf. This gives
segfault in igb_tx_done_cleanup() as sw_ring[tx_id].mbuf is not checked before
calling rte_pktmbuf_free_seg().
Driver code did't changed much since v19.05 so I think that the bug is still
present.
