2018-10-07DHCPv4: syscall -> x/sys/unixSean Karlage
Fixes #156 Build a simple client like so: ``` package main import ( "fmt" "time" "github.com/insomniacslk/dhcp/dhcpv4" ) func main() { client := dhcpv4.Client{ReadTimeout: 5 * time.Second, WriteTimeout: 5 * time.Second} conversation, err := client.Exchange("en0", nil) if err != nil { fmt.Println(err) } for _, m := range conversation { fmt.Println(m.Summary()) } } ``` and run: ``` $ sudo ./main Password: DHCPv4 opcode=BootRequest hwtype=Ethernet hwaddrlen=6 hopcount=0 transactionid=0xabfad715 numseconds=0 flags=Broadcast (0x8000) clientipaddr=0.0.0.0 youripaddr=0.0.0.0 serveripaddr=0.0.0.0 gatewayipaddr=0.0.0.0 clienthwaddr=8c:85:90:20:2e:33 serverhostname= bootfilename= options= DHCP Message Type -> DISCOVER Parameter Request List -> [Subnet Mask, Router, Domain Name, Domain Name Server] End -> [] DHCPv4 opcode=BootReply hwtype=Ethernet hwaddrlen=6 hopcount=0 transactionid=0xabfad715 numseconds=0 flags=Broadcast (0x8000) clientipaddr=0.0.0.0 youripaddr=192.168.0.105 serveripaddr=0.0.0.0 gatewayipaddr=0.0.0.0 clienthwaddr=8c:85:90:20:2e:33 serverhostname= bootfilename= options= DHCP Message Type -> OFFER Server Identifier -> 192.168.0.1 IP Addresses Lease Time -> 5648 Subnet Mask -> ffffff00 Routers -> 192.168.0.1 Domain Name Servers -> 8.8.8.8, 8.8.4.4 End -> [] DHCPv4 opcode=BootRequest hwtype=Ethernet hwaddrlen=6 hopcount=0 transactionid=0xabfad715 numseconds=0 flags=Broadcast (0x8000) clientipaddr=0.0.0.0 youripaddr=0.0.0.0 serveripaddr=192.168.0.1 gatewayipaddr=0.0.0.0 clienthwaddr=8c:85:90:20:2e:33 serverhostname= bootfilename= options= DHCP Message Type -> REQUEST Requested IP Address -> 192.168.0.105 Server Identifier -> 192.168.0.1 End -> [] DHCPv4 opcode=BootReply hwtype=Ethernet hwaddrlen=6 hopcount=0 transactionid=0xabfad715 numseconds=0 flags=Broadcast (0x8000) clientipaddr=0.0.0.0 youripaddr=192.168.0.105 serveripaddr=0.0.0.0 gatewayipaddr=0.0.0.0 clienthwaddr=8c:85:90:20:2e:33 serverhostname= bootfilename= options= DHCP Message Type -> ACK Server Identifier -> 192.168.0.1 IP Addresses Lease Time -> 7200 Subnet Mask -> ffffff00 Routers -> 192.168.0.1 Domain Name Servers -> 8.8.8.8, 8.8.4.4 End -> [] ```

2018-10-03BSDP: Fix MessageTypeFromPacket to return a pointerSean Karlage
As @insomiacslk pointed out in #161, it's probably better to return a pointer rather than a (MessageType, bool) combo.

2018-10-01BSDP: Add MessageTypeFromPacket helperSean Karlage
This is a helper function to extract the BSDP message type from a given `dhcpv4.DHCPv4` packet structure. It's useful in helping to identify what kind of BSDP packet you're dealing with (since the distinction is only made in one of the vendor-specific options encapsulated in Option 43).
2018-09-29BSDP: Fix parsing offset for boot image listsSean Karlage
While parsing boot images, the current code reads to the end of the data stream; however, this could lead to reading past the boot image option and reading into the next option. Instead, contain how far the option parsing code reads by only looking at the max length specified in the option.
