From 76253e73f9c9c24fec755e485516f3b55d0707b4 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Wed, 8 Oct 2014 14:15:45 -0500 Subject: [PATCH] sd-dhcp-client: support non-Ethernet hardware addresses Like Infiniband. See RFC 4390 section 2.1 for details on DHCP and Infiniband; chaddr is zeroed, hlen is set to 0, and htype is set to ARPHRD_INFINIBAND because IB hardware addresses are 20 bytes in length. --- src/libsystemd-network/dhcp-internal.h | 10 ++-- src/libsystemd-network/dhcp-network.c | 54 ++++++++++++++++++---- src/libsystemd-network/dhcp-packet.c | 8 ++-- src/libsystemd-network/sd-dhcp-client.c | 74 +++++++++++++++++++++++------- src/libsystemd-network/sd-dhcp-server.c | 8 ++-- src/libsystemd-network/sd-dhcp6-client.c | 36 +++++++++++---- src/libsystemd-network/test-dhcp-client.c | 14 ++++-- src/libsystemd-network/test-dhcp-option.c | 2 +- src/libsystemd-network/test-dhcp6-client.c | 8 +++- src/network/networkd-dhcp4.c | 4 +- src/network/networkd-link.c | 12 +++-- src/systemd/sd-dhcp-client.h | 4 +- src/systemd/sd-dhcp6-client.h | 4 +- 13 files changed, 179 insertions(+), 59 deletions(-) diff --git a/src/libsystemd-network/dhcp-internal.h b/src/libsystemd-network/dhcp-internal.h index 1069c8a03b..d358a49307 100644 --- a/src/libsystemd-network/dhcp-internal.h +++ b/src/libsystemd-network/dhcp-internal.h @@ -24,6 +24,7 @@ #include #include +#include #include #include "socket-util.h" @@ -31,7 +32,9 @@ #include "sd-dhcp-client.h" #include "dhcp-protocol.h" -int dhcp_network_bind_raw_socket(int index, union sockaddr_union *link, uint32_t xid, struct ether_addr mac_addr); +int dhcp_network_bind_raw_socket(int index, union sockaddr_union *link, + uint32_t xid, const uint8_t *mac_addr, + size_t mac_addr_len, uint16_t arp_type); int dhcp_network_bind_udp_socket(be32_t address, uint16_t port); int dhcp_network_send_raw_socket(int s, const union sockaddr_union *link, const void *packet, size_t len); @@ -47,8 +50,9 @@ typedef int (*dhcp_option_cb_t)(uint8_t code, uint8_t len, int dhcp_option_parse(DHCPMessage *message, size_t len, dhcp_option_cb_t cb, void *user_data); -int dhcp_message_init(DHCPMessage *message, uint8_t op, uint32_t xid, uint8_t type, - size_t optlen, size_t *optoffset); +int dhcp_message_init(DHCPMessage *message, uint8_t op, uint32_t xid, + uint8_t type, uint16_t arp_type, size_t optlen, + size_t *optoffset); uint16_t dhcp_packet_checksum(uint8_t *buf, size_t len); diff --git a/src/libsystemd-network/dhcp-network.c b/src/libsystemd-network/dhcp-network.c index 1ced5cf292..29e9993f66 100644 --- a/src/libsystemd-network/dhcp-network.c +++ b/src/libsystemd-network/dhcp-network.c @@ -22,6 +22,7 @@ #include #include #include +#include #include #include #include @@ -32,9 +33,12 @@ #include "dhcp-internal.h" -int dhcp_network_bind_raw_socket(int ifindex, union sockaddr_union *link, - uint32_t xid, struct ether_addr mac_addr) { - +static int _bind_raw_socket(int ifindex, union sockaddr_union *link, + uint32_t xid, const uint8_t *mac_addr, + size_t mac_addr_len, + const uint8_t *bcast_addr, + const struct ether_addr *eth_mac, + uint16_t arp_type, uint8_t dhcp_hlen) { struct sock_filter filter[] = { BPF_STMT(BPF_LD + BPF_W + BPF_LEN, 0), /* A <- packet length */ BPF_JUMP(BPF_JMP + BPF_JGE + BPF_K, sizeof(DHCPPacket), 1, 0), /* packet >= DHCPPacket ?
