Also, implement size-aware int parsing. With this patch we can now express flows such as the following: "eth(src=0a:ca:fe:ca:fe:0a/ff:ff:00:00:ff:00)" "eth(src=0a:ca:fe:ca:fe:0a)" -> mask = ff:ff:ff:ff:ff:ff "ipv4(src=192.168.1.1)" -> mask = 255.255.255.255 "ipv4(src=192.168.1.1/24)" "ipv4(src=192.168.1.1/255.255.255.0)" "tcp(src=8080)" -> mask = 0xffff "tcp(src=8080/0xf0f0)" Signed-off-by: Adrian Moreno --- .../selftests/net/openvswitch/ovs-dpctl.py | 96 ++++++++++++------- 1 file changed, 64 insertions(+), 32 deletions(-) diff --git a/tools/testing/selftests/net/openvswitch/ovs-dpctl.py b/tools/testing/selftests/net/openvswitch/ovs-dpctl.py index 61c4d7b75261..0bc944f36e02 100644 --- a/tools/testing/selftests/net/openvswitch/ovs-dpctl.py +++ b/tools/testing/selftests/net/openvswitch/ovs-dpctl.py @@ -169,25 +169,45 @@ def parse_ct_state(statestr): return parse_flags(statestr, ct_flags) -def convert_mac(mac_str, mask=False): - if mac_str is None or mac_str == "": - mac_str = "00:00:00:00:00:00" - if mask is True and mac_str != "00:00:00:00:00:00": - mac_str = "FF:FF:FF:FF:FF:FF" - mac_split = mac_str.split(":") - ret = bytearray([int(i, 16) for i in mac_split]) - return bytes(ret) +def convert_mac(data): + def to_bytes(mac): + mac_split = mac.split(":") + ret = bytearray([int(i, 16) for i in mac_split]) + return bytes(ret) + mac_str, _, mask_str = data.partition('/') -def convert_ipv4(ip, mask=False): - if ip is None: - ip = 0 - if mask is True: - if ip != 0: - ip = int(ipaddress.IPv4Address(ip)) & 0xFFFFFFFF + if not mac_str: + mac_str = mask_str = "00:00:00:00:00:00" + elif not mask_str: + mask_str = "FF:FF:FF:FF:FF:FF" - return int(ipaddress.IPv4Address(ip)) + return to_bytes(mac_str), to_bytes(mask_str) +def convert_ipv4(data): + ip, _, mask = data.partition('/') + + if not ip: + ip = mask = 0 + elif not mask: + mask = 0xFFFFFFFF + elif mask.isdigit(): + mask = (0xFFFFFFFF << (32 - int(mask))) & 0xFFFFFFFF + + return int(ipaddress.IPv4Address(ip)), int(ipaddress.IPv4Address(mask)) + +def convert_int(size): + def convert_int_sized(data): + value, _, mask = data.partition('/') + + if not value: + return 0, 0 + elif not mask: + return int(value, 0), pow(2, size) - 1 + else: + return int(value, 0), int(mask, 0) + + return convert_int_sized def parse_starts_block(block_str, scanstr, returnskipped, scanregex=False): if scanregex: @@ -628,8 +648,10 @@ class ovskey(nla): ) fields_map = ( - ("src", "src", "%d", lambda x: int(x) if x is not None else 0), - ("dst", "dst", "%d", lambda x: int(x) if x is not None else 0), + ("src", "src", "%d", lambda x: int(x) if x else 0, + convert_int(16)), + ("dst", "dst", "%d", lambda x: int(x) if x else 0, + convert_int(16)), ) def __init__( @@ -678,17 +700,13 @@ class ovskey(nla): data = flowstr[:splitchar] flowstr = flowstr[splitchar:] else: - data = None + data = "" if len(f) > 4: - func = f[4] - else: - func = f[3] - k[f[0]] = func(data) - if len(f) > 4: - m[f[0]] = func(data, True) + k[f[0]], m[f[0]] = f[4](data) else: - m[f[0]] = func(data) + k[f[0]] = f[3](data) + m[f[0]] = f[3](data) flowstr = flowstr[strspn(flowstr, ", ") :] if len(flowstr) == 0: @@ -792,10 +810,14 @@ class ovskey(nla): int, convert_ipv4, ), - ("proto", "proto", "%d", lambda x: int(x) if x is not None else 0), - ("tos", "tos", "%d", lambda x: int(x) if x is not None else 0), - ("ttl", "ttl", "%d", lambda x: int(x) if x is not None else 0), - ("frag", "frag", "%d", lambda x: int(x) if x is not None else 0), + ("proto", "proto", "%d", lambda x: int(x) if x else 0, + convert_int(8)), + ("tos", "tos", "%d", lambda x: int(x) if x else 0, + convert_int(8)), + ("ttl", "ttl", "%d", lambda x: int(x) if x else 0, + convert_int(8)), + ("frag", "frag", "%d", lambda x: int(x) if x else 0, + convert_int(8)), ) def __init__( @@ -931,8 +953,8 @@ class ovskey(nla): ) fields_map = ( - ("type", "type", "%d", int), - ("code", "code", "%d", int), + ("type", "type", "%d", lambda x: int(x) if x else 0), + ("code", "code", "%d", lambda x: int(x) if x else 0), ) def __init__( @@ -997,7 +1019,7 @@ class ovskey(nla): int, convert_ipv4, ), - ("op", "op", "%d", lambda x: int(x) if x is not None else 0), + ("op", "op", "%d", lambda x: int(x) if x else 0), ( "sha", "sha", @@ -1201,6 +1223,16 @@ class ovskey(nla): "tcp", ovskey.ovs_key_tcp, ), + ( + "OVS_KEY_ATTR_UDP", + "udp", + ovskey.ovs_key_udp, + ), + ( + "OVS_KEY_ATTR_ICMP", + "icmp", + ovskey.ovs_key_icmp, + ), ( "OVS_KEY_ATTR_TCP_FLAGS", "tcp_flags",
