Subject: [PATCH bpf] selftests/bpf: add XDP_UMEM_TX_METADATA_LEN flag to umem_config
Date: Fri, 20 Dec 2024 17:18:06 +0800 [thread overview]
Message-ID: <20241220091806.1856223-1-wei.fang@nxp.com> (raw)
The Tx metadata test has been broken since the commit d5e726d9143c ("xsk:
Require XDP_UMEM_TX_METADATA_LEN to actuate tx_metadata_len"). Because
this change requires XDP_UMEM_TX_METADATA_LEN flag to be set, otherwise
xsk_buff_pool::tx_metadata_len will be initialized to 0, which means that
the driver cannot get Tx metadata and cannot execute AF_XDP Tx metadata
hooks.
Fixes: d5e726d9143c ("xsk: Require XDP_UMEM_TX_METADATA_LEN to actuate tx_metadata_len")
