Issue

Description of problem: When run ptp4l using udpv4 on a port without ipv4 address, it won't report error. In this case the address in SYNC packets is from another port. ip addr show ens4f0np0 6: ens4f0np0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 00:0f:53:7f:88:a0 brd ff:ff:ff:ff:ff:ff altname enp175s0f0np0 inet6 fe80::20f:53ff:fe7f:88a0/64 scope link valid_lft forever preferred_lft forever ptp4l -EH4mi ens4f0np0 ptp4l[72743.712]: selected /dev/ptp4 as PTP clock ptp4l[72743.713]: port 1: INITIALIZING to LISTENING on INIT_COMPLETE ptp4l[72743.713]: port 0: INITIALIZING to LISTENING on INIT_COMPLETE ptp4l[72743.713]: port 0: INITIALIZING to LISTENING on INIT_COMPLETE ptp4l[72751.711]: port 1: LISTENING to MASTER on ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES ptp4l[72751.711]: selected local clock 000f53.fffe.7f88a0 as best master ptp4l[72751.711]: port 1: assuming the grand master role Version-Release number of selected component (if applicable): The address in SYNC packets is assigned to another port in this server: ip addr show eno1 2: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 34:73:5a:99:97:ac brd ff:ff:ff:ff:ff:ff altname enp24s0f0 inet 10.73.131.75/23 brd 10.73.131.255 scope global dynamic noprefixroute eno1 valid_lft 35939sec preferred_lft 35939sec inet6 2620:52:0:4982:3673:5aff:fe99:97ac/64 scope global dynamic noprefixroute valid_lft 2591998sec preferred_lft 604798sec inet6 fe80::3673:5aff:fe99:97ac/64 scope link noprefixroute valid_lft forever preferred_lft forever Frame 3: 86 bytes on wire (688 bits), 86 bytes captured (688 bits) on interface 0 Interface id: 0 (ens4f0np0) Interface name: ens4f0np0 Encapsulation type: Ethernet (1) Arrival Time: Nov 28, 2022 20:27:54.447241961 EST [Time shift for this packet: 0.000000000 seconds] Epoch Time: 1669685274.447241961 seconds [Time delta from previous captured frame: 0.058639484 seconds] [Time delta from previous displayed frame: 0.058639484 seconds] [Time since reference or first frame: 0.059437985 seconds] Frame Number: 3 Frame Length: 86 bytes (688 bits) Capture Length: 86 bytes (688 bits) [Frame is marked: False] [Frame is ignored: False] [Protocols in frame: eth:ethertype:ip:udp:ptp] Ethernet II, Src: Solarfla_7f:88:a0 (00:0f:53:7f:88:a0), Dst: IPv4mcast_01:81 (01:00:5e:00:01:81) Destination: IPv4mcast_01:81 (01:00:5e:00:01:81) Address: IPv4mcast_01:81 (01:00:5e:00:01:81) .... ..0. .... .... .... .... = LG bit: Globally unique address (factory default) .... ...1 .... .... .... .... = IG bit: Group address (multicast/broadcast) Source: Solarfla_7f:88:a0 (00:0f:53:7f:88:a0) Address: Solarfla_7f:88:a0 (00:0f:53:7f:88:a0) .... ..0. .... .... .... .... = LG bit: Globally unique address (factory default) .... ...0 .... .... .... .... = IG bit: Individual address (unicast) Type: IPv4 (0x0800) Internet Protocol Version 4, Src: 10.73.131.75, Dst: 224.0.1.129 0100 .... = Version: 4 .... 0101 = Header Length: 20 bytes (5) Differentiated Services Field: 0x00 (DSCP: CS0, ECN: Not-ECT) 0000 00.. = Differentiated Services Codepoint: Default (0) .... ..00 = Explicit Congestion Notification: Not ECN-Capable Transport (0) Total Length: 72 Identification: 0x72aa (29354) Flags: 0x4000, Don't fragment 0... .... .... .... = Reserved bit: Not set .1.. .... .... .... = Don't fragment: Set ..0. .... .... .... = More fragments: Not set ...0 0000 0000 0000 = Fragment offset: 0 Time to live: 1 Protocol: UDP (17) Header checksum: 0x97e5 [validation disabled] [Header checksum status: Unverified] Source: 10.73.131.75 Destination: 224.0.1.129 User Datagram Protocol, Src Port: 319, Dst Port: 319 Source Port: 319 Destination Port: 319 Length: 52 Checksum: 0x6f5b [unverified] [Checksum Status: Unverified] [Stream index: 2] Precision Time Protocol (IEEE1588) 0000 .... = transportSpecific: 0x0 ...0 .... = V1 Compatibility: False .... 0000 = messageId: Sync Message (0x0) .... 0010 = versionPTP: 2 messageLength: 44 subdomainNumber: 0 flags: 0x0200 0... .... .... .... = PTP_SECURITY: False .0.. .... .... .... = PTP profile Specific 2: False ..0. .... .... .... = PTP profile Specific 1: False .... .0.. .... .... = PTP_UNICAST: False .... ..1. .... .... = PTP_TWO_STEP: True .... ...0 .... .... = PTP_ALTERNATE_MASTER: False .... .... ..0. .... = FREQUENCY_TRACEABLE: False .... .... ...0 .... = TIME_TRACEABLE: False .... .... .... 0... = PTP_TIMESCALE: False .... .... .... .0.. = PTP_UTC_REASONABLE: False .... .... .... ..0. = PTP_LI_59: False .... .... .... ...0 = PTP_LI_61: False correction: 0.000000 nanoseconds correction: Ns: 0 nanoseconds correctionSubNs: 0 nanoseconds ClockIdentity: 0x000f53fffe7f88a0 SourcePortID: 1 sequenceId: 66 control: Sync Message (0) logMessagePeriod: 0 originTimestamp (seconds): 0 originTimestamp (nanoseconds): 0 How reproducible: always Steps to Reproduce: 1.run ptp4l on a port without ipv4 address assigned 2. 3.
