Patch 1 extends ovs-dpctl.py with vlan(vid=X,pcp=Y,cfi=Z) formatting and parsing, plus an encap_ovskey subclass for safe ENCAP NLA decoding. It changes OVS_KEY_ATTR_VLAN type from uint16 to be16 to match the kernel __be16 wire format. It also adds push_vlan action support (parse/format with range validation). Patch 2 adds the selftest using purely ping-based verification with a push_vlan return flow for symmetric bidirectional testing. Tested with vng on x86_64, all OVS selftests pass (including new test_pop_vlan). v10: - fix masked VLAN dpstr round-trip: use tci=0xNNNN/0xMMMM format for masked vlan() output instead of vid=X,pcp=Y,cfi=Z/vid=... which the parser cannot re-consume - fix int() base handling in _parse_vlan_from_flowstr: use int(val, 0) for auto base detection instead of manual 0x prefix check - fix commit message: remove reference to nonexistent MAX_ENCAP_DEPTH constant, clarify "encap parse()" scope v9: https://lore.kernel.org/netdev/20260509135423.3433910-1-houminxi@gmail.com/ - rebase on net-next (resolve conflict with 05416ada37aa4 "selftests: openvswitch: add tests for tunnel vport refcounting") v8: https://lore.kernel.org/netdev/20260508134308.2857449-1-houminxi@gmail.com/ - consistent error message prefix: push_vlan() instead of push_vlan (matches vlan() and encap() style) - unify encap() error messages for clarity - add empty-string guards for MAC address variables - remove slot number comments from encap_ovskey nla_map - remove explicit modprobe 8021q pre-flight check v7: https://lore.kernel.org/netdev/20260507131541.2331771-1-houminxi@gmail.com/ - remove slot number comments from encap_ovskey nla_map, keep only comments explaining differences from base ovskey class - remove explicit modprobe 8021q pre-flight check (ip link add type vlan auto-loads the module) v6: https://lore.kernel.org/netdev/20260506131218.1880852-1-houminxi@gmail.com/ - fix non-ASCII characters (em dashes) in comments and commit messages v5: https://lore.kernel.org/netdev/20260505124957.1239812-1-houminxi@gmail.com/ - add push_vlan action class, dpstr format and parse with range validation (vid 0-4095, pcp 0-7, tpid 0-0xFFFF, CFI forced to 1) - remove MAX_ENCAP_DEPTH constant and depth tracking (bracket-depth counter in encap parser already handles nesting) - remove start_capture/stop_capture helpers and tcpdump/pcap verification -- use ping success/failure instead - remove modprobe/netns pre-flight checks (other tests don't do this) - remove ethtool VLAN offload disable (unnecessary for veth) - add push_vlan return flow for symmetric bidirectional ping - use ovs_sbx wrapper for ping commands (consistent with siblings) v4: https://lore.kernel.org/netdev/20260504123713.555461-1-houminxi@gmail.com/ - fix all checkpatch line-length warnings in new code - fix pylint W0707: use explicit exception chaining (from exc) v3: https://lore.kernel.org/netdev/20260503120946.51869-1-houminxi@gmail.com/ - encap_ovskey: MPLS type "ovs_key_mpls" -> "array(ovs_key_mpls)" - encap_ovskey: PRIORITY/IN_PORT set to "none" (metadata, not in ENCAP) - _vlan_dpstr: cfi=0 falls back to tci=0x%04x for round-trip safety - encap parse(): check return value for unrecognized trailing content - vlan parser: boundary check + raise-from for exception chaining v2: https://lore.kernel.org/netdev/20260501133924.3100680-1-houminxi@gmail.com/ Minxi Hou (2): selftests: openvswitch: add vlan() and encap() flow string parsing selftests: openvswitch: add pop_vlan test .../selftests/net/openvswitch/openvswitch.sh | 78 +++++ .../selftests/net/openvswitch/ovs-dpctl.py | 324 +++++++++++++++++- 2 files changed, 392 insertions(+), 10 deletions(-) -- 2.53.0
