udhcpd: send DHCPOFFERs as unicast (unless clients specifically asks for bcast)

2025-04-07T00:46:39+00:00

RFC 2131 says we should do that. Evidently, since for so many years no one complained, sending them broadcast works too, but finally we've got someone who wants RFC-compliand behavior. function old new delta send_packet 141 179 +38 .rodata 105680 105681 +1 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 39/0) Total: 39 bytes Signed-off-by: Denys Vlasenko

udhcpc6: generate a consistent IAID

2025-02-09T12:51:33+00:00

Currently, udhcpc6 does not meet the requirements for Identity Association in RFC 3315. This is a specific explanation in RFC 3315 protocol: https://datatracker.ietf.org/doc/html/rfc3315#section-10 "The IAID uniquely identifies the IA and must be chosen to be unique among the IAIDs on the client. The IAID is chosen by the client. For any given use of an IA by the client, the IAID for that IA MUST be consistent across restarts of the DHCP client." This patch makes the client generate a consistent IAID based on the MAC address. function old new delta send_d6_discover 285 270 -15 Signed-off-by: Zhou Siqi Signed-off-by: Denys Vlasenko

udhcpc6: improvements

2025-02-09T11:52:02+00:00

Several small improvements to udhcpc6. - Remove usage text for the nonexistent -B option. - Fix a segfault when renewing an IA_PD lease without IA_NA (which means the client hasn't been assigned an ip, so we cannot locally bind to it). - Fix NAK management: check the option length, and print the status code and status message - Add a -m option to always send renew requests as multicast. These last two changes are useful to deal with hopelessly broken DHCPv6 servers such as the one from the Orange Livebox (one of the main French ISPs) which I'm currently having the displeasure to have to talk to, hence the patch. function old new delta static.send_d6_renew - 126 +126 .rodata 105598 105649 +51 udhcpc6_main 2607 2650 +43 packed_usage 34933 34953 +20 d6_send_kernel_packet_from_client_data_ifindex 266 282 +16 send_d6_renew 174 - -174 ------------------------------------------------------------------------------ (add/remove: 1/1 grow/shrink: 4/0 up/down: 256/-174) Total: 82 bytes Signed-off-by: Laurent Bercot Signed-off-by: Denys Vlasenko

networking/libiproute/iplink.c: fix support for older kernels

2024-10-06T16:25:01+00:00

- The CAN netlink interface has been added in Linux v2.6.31 with only 3 options [1]: CAN_CTRLMODE_LOOPBACK 0x1 /* Loopback mode */ CAN_CTRLMODE_LISTENONLY 0x2 /* Listen-only mode */ CAN_CTRLMODE_3_SAMPLES 0x4 /* Triple sampling mode */ So define the other options. - IFLA_CAN_TERMINATION has been added in Linux 4.11 [2], define it for older kernels.
