* [ipv6] Handle IPv6 option length correctlyMichael Brown2013-10-231-1/+1
| | | | | | | The IPv6 option length field represents the length of the option data field, not the overall length of the option. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [ipv6] Fix uninitialised-variable warningMichael Brown2013-09-031-0/+3
| | | | | | Fix uninitialised-variable warning reported by gcc 4.5.2. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [ipv6] Replace IPv6 stackMichael Brown2013-09-034-480/+1097
| | | | | | | | | | | | | | | | Replace the existing partially-implemented IPv6 stack with a fresh implementation. This implementation is not yet complete. The IPv6 transmit and receive datapaths are functional (including fragment reassembly and parsing of arbitrary extension headers). NDP neighbour solicitations and advertisements are supported. ICMPv6 echo is supported. At present, only link-local addresses may be used, and there is no way to specify an IPv6 address as part of a URI (either directly or via a DNS lookup). Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [neighbour] Generalise concept of neighbour discoveryMichael Brown2013-09-032-354/+513
| | | | | | | | Split the protocol-independent portions of arp.c into a separate file neighbour.c, to allow for sharing of functionality between IPv4+ARP and IPv6+NDP. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [tcpip] Pass through network device to transport layer protocolsMichael Brown2013-09-037-10/+21
| | | | | | | NDP requires knowledge of the network device on which a packet was received. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [ethernet] Add support for generating multicast hash for IPv6 addressesMichael Brown2013-09-031-0/+5
| | | | Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [netdevice] Add method for generating EUI-64 address from link-layer addressMichael Brown2013-09-032-0/+17
| | | | Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [netdevice] Add concept of a network device indexMichael Brown2013-09-031-2/+3
| | | | | | | | | | | | | IPv6 link-local socket addresses require some way to specify a local network device. We cannot simply use a pointer to the network device, since a struct sockaddr_in6 may be long-lived and has no way to hold a reference to the network device. Using a network device index allows a socket address to cleanly refer to a network device without worrying about whether or not that device continues to exist. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [ipv4] Generalise fragment reassembly mechanismMichael Brown2013-08-272-117/+211
| | | | | | | Generalise the concept of fragment reassembly to allow for code sharing between IPv4 and IPv6 protocols. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [linux] Give tap devices a name and bus typeMichael Brown2013-08-271-1/+2
| | | | | | | | Give tap devices a meaningful name, and avoid segmentation faults when attempting to retrieve ${net0/bustype} by assigning a new bus type for tap devices. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [http] Add support for HTTP POSTMichael Brown2013-08-191-3/+121
| | | | | | | | | | | | | | Allow HTTP POST requests to be generated when the URI includes a parameter list. For example: #!ipxe params param mac ${net0/mac} param uuid ${uuid} param asset ${asset} chain http://boot.ipxe.org/demo/boot.php##params Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [udp] Move high-frequency debug messages to DBGLVL_EXTRAMichael Brown2013-08-061-5/+5
| | | | | | | | This makes it possible to leave UDP debugging enabled in order to see interesting UDP events, without flooding the console with at least one message per packet. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [settings] Clarify usage of the term "named setting"Michael Brown2013-07-181-1/+1
| | | | | | | | | | | | There are currently two conflicting usages of the term "named setting" within iPXE: one refers to predefined settings (such as show up in the "config" UI), the other refers to settings identified by a name (such as "net0.dhcp/ip"). Split these usages into the term "predefined setting" and "named setting" to avoid ambiguity. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [cmdline] Accept "netX" in iPXE commandsMichael Brown2013-07-131-0/+5
| | | | | | | Allow any iPXE command expecting a network device name to accept "netX" as a synonym for "most recently opened network device". Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [settings] Make "netX" settings block function as a symbolic linkMichael Brown2013-07-131-0/+49
| | | | | | | | | | | | | | Add a facility for settings blocks to act as symbolic links to other settings blocks, and reimplement the "netX" virtual settings block using this facility. The primary advantage of this approach is that unscoped settings such as ${mac} and ${filename} will now reflect the settings obtained from the most recently opened network device: in most cases, this will mean the settings obtained from the most recent DHCP attempt. This should improve conformance to the principle of least astonishment. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [tcp] Do not send RST for unrecognised connectionsMichael Brown2013-07-121-1/+0Star
| | | | | | | | | | | | On large networks with substantial numbers of monitoring agents, unwanted TCP connection attempts may end up flooding iPXE's ARP cache. Fix by silently dropping packets received for unrecognised TCP connections. This should not cause problems, since many firewalls will also silently drop any such packets.

* [settings] Eliminate settings "tag magic"Michael Brown2013-05-013-23/+4Star
| | | | | | | Create an explicit concept of "settings scope" and eliminate the magic values used for numerical setting tags. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [netdevice] Add netdev_tx_defer() to allow drivers to defer transmissionsMichael Brown2013-05-011-3/+87
| | | | | | | | Devices with small transmit descriptor rings may temporarily run out of space. Provide netdev_tx_defer() to allow drivers to defer packets for retransmission as soon as a descriptor becomes available. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [netdevice] Use link-layer address as part of RNG seedMichael Brown2013-04-191-2/+11
| | | | | | | | | | | | | | | | | | | | iPXE currently seeds the random number generator using the system timer tick count. When large numbers of machines are booted simultaneously, multiple machines may end up choosing the same DHCP transaction ID (XID) value; this can cause problems. Fix by using the least significant (and hence most variable) bits of each network device's link-layer address to perturb the random number generator. This introduces some per-machine unique data into the random number generator's seed, and so reduces the chances of DHCP XID collisions. This does not affect the ANS X9.82-compatible random bit generator used by TLS and other cryptography code, which uses an entirely separate source of entropy.

* [dhcp] Use PXE byte ordering for UUID in DHCP option 97Michael Brown2013-03-201-1/+8
| | | | | | | | The PXE spec does not specify a byte ordering for UUIDs, but RFC4578 suggests that it follows the EFI spec, in which the first three fields are little-endian. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [tftp] Allow TFTP block size to be controlled via the PXE TFTP APIMichael Brown2013-03-061-20/+8Star
| | | | | | | | | | | | | | The PXE TFTP API allows the caller to request a particular TFTP block size. Since mid-2008, iPXE has appended a "?blksize=xxx" parameter to the TFTP URI constructed internally; nothing has ever parsed this parameter. Nobody seems to have cared that this parameter has been ignored for almost five years. Fix by using xfer_window(), which provides a fairly natural way to convey the block size information from the PXE TFTP API to the TFTP protocol layer. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [netdevice] Separate VLAN support from presence of VLAN-supporting driversMichael Brown2013-03-011-0/+12
| | | | | | | | | | | | | | | | Some NICs (e.g. Hermon) provide hardware support for stripping the VLAN tag, but do not provide any way for this support to be disabled. Drivers for this hardware must therefore call vlan_find() to identify a suitable receiving network device. Provide a weak version of vlan_find() which will always return NULL if VLAN support has not been enabled (either directly, or by enabling a feature such as FCoE which requires VLAN support). This allows the VLAN code to be omitted from builds where the user has not requested support for VLANs.

* [netdevice] Add vlan_tag() to get the VLAN tag of a network deviceStefan Hajnoczi2013-03-012-0/+28
| | | | | | | | | | | | The iBFT has a VLAN field that should be filled in. Add the vlan_tag() function to extract the VLAN tag of a network device. Since VLAN support is optional, define a weak function that returns 0 when iPXE is built without VLAN support.

* [netdevice] Do not force a poll on net_tx()Michael Brown2012-10-241-7/+0Star
| | | | | | | | | | | | | | Including a netdev_poll() within net_tx() can cause the net_step() loop to end up processing hundreds or thousands of packets within a single step, since each received packet being processed may trigger a response which, in turn causes a poll for further received packets. Network devices must now ensure that the TX ring is at least as large as the RX ring, in order to avoid running out of TX descriptors. This should not cause any problems; unlike the RX ring, there is no substantial memory cost incurred by increasing the TX ring size. Signed-off-by: Michael Brown <mcb30@ipxe.org>
