Test-Label: intel-Testing Test-Status: SUCCESS _Testing PASS_ DPDK git repo: dpdk-next-net-intel commit 8f897ab119ffe4b495b87f53b561cf83847be602 Author: Stephen Hemminger Date: Fri Nov 14 10:21:31 2025 -0800 net/e1000: add check for filter mask range Gcc-16 complains about possible reference outside of array when managing flex filter. This is a false positive because the filter length can never be that long, but compiler can't detect that. Add guard rail check to only loop over possible array. ../drivers/net/intel/e1000/igb_ethdev.c:4265:23: note: at offset 152 into destination object of size 176 allocated by ‘rte_zmalloc’ 4265 | flex_filter = rte_zmalloc("e1000_flex_filter", | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 4266 | sizeof(struct e1000_flex_filter), 0); | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ../drivers/net/intel/e1000/igb_ethdev.c:4280:50: warning: writing 64 bytes into a region of size 0 [-Wstringop-overflow=] 4280 | flex_filter->filter_info.mask[i] = mask; | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~ Signed-off-by: Stephen Hemminger Reviewed-by: Anatoly Burakov Testing Summary : 18 Case Done, 18 Successful, 0 Failures TestPlan: pf_smoke: http://git.dpdk.org/tools/dts/tree/test_plans/pf_smoke_test_plan.rst vf_smoke: http://git.dpdk.org/tools/dts/tree/test_plans/vf_smoke_test_plan.rst virtio_smoke: http://git.dpdk.org/tools/dts/tree/test_plans/virtio_smoke_test_plan.rst TestSuite: pf_smoke: http://git.dpdk.org/tools/dts/tree/tests/TestSuite_pf_smoke.py vf_smoke: http://git.dpdk.org/tools/dts/tree/tests/TestSuite_vf_smoke.py virtio_smoke: http://git.dpdk.org/tools/dts/tree/tests/TestSuite_virtio_smoke.py OS : Ubuntu 24.04.3 LTS Kernel : 6.8.0-71-generic GCC : 13.3.0-6ubuntu2~24.04 NIC : Ethernet Controller XL710 for 40GbE QSFP+ Target : x86_64-native-linuxapp-gcc Test result details: +-------------+---------------------------+-------+ | suite | case | status| +-------------+---------------------------+-------+ | asan_smoke | test_rxtx_with_ASan_enable| passed| | pf_smoke | test_pf_jumbo_frames | passed| | pf_smoke | test_pf_rss | passed| | pf_smoke | test_pf_tx_rx_queue | passed| | vf_smoke | test_vf_rss | passed| | vf_smoke | test_vf_tx_rx_queue | passed| | vf_smoke | test_vf_jumbo_frames | n/a | | virtio_smoke| test_virtio_loopback | passed| | virtio_smoke| test_virtio_pvp | passed| +-------------+---------------------------+-------+ OS : Ubuntu 24.04.3 LTS Kernel : 6.8.0-87-generic GCC : 13.3.0-6ubuntu2~24.04 NIC : Ethernet Controller E810-C for SFP Target : x86_64-native-linuxapp-gcc Test result details: +-------------+---------------------------+-------+ | suite | case | status| +-------------+---------------------------+-------+ | asan_smoke | test_rxtx_with_ASan_enable| passed| | pf_smoke | test_pf_jumbo_frames | passed| | pf_smoke | test_pf_rss | passed| | pf_smoke | test_pf_tx_rx_queue | passed| | vf_smoke | test_vf_jumbo_frames | passed| | vf_smoke | test_vf_rss | passed| | vf_smoke | test_vf_tx_rx_queue | passed| | virtio_smoke| test_virtio_loopback | passed| | virtio_smoke| test_virtio_pvp | passed| +-------------+---------------------------+-------+ DPDK STV team
