* [vesafb] Include raw status value within VBE error messagesMichael Brown2013-11-281-5/+5
| | | | Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [vesafb] Add VESA frame buffer consoleMichael Brown2013-11-285-0/+635
| | | | | | | | | | | The VESA frame buffer console uses the VESA BIOS extensions (VBE) to enumerate video modes, selects an appropriate mode, and then hands off to the generic frame buffer code. The font is extracted from the VGA BIOS, avoiding the need to provide an external font file. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [fbcon] Add generic concept of a frame buffer consoleMichael Brown2013-11-284-1/+894
| | | | | | | Add support for a simple frame buffer console, using single buffering and a fixed-width bitmap font. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [main] Defer "initialising devices" message until initialising devicesMichael Brown2013-11-271-1/+3
| | | | | | | | Allow the "initialising devices" message to show up on consoles which require initialisation, by deferring it until after initialise() has completed. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [test] Include failing code within failed test result outputMichael Brown2013-11-272-6/+9

* [ipv6] Separate the concepts of prefix and address creationMichael Brown2013-11-154-124/+201
| | | | | | | | Allow for IPv6 routing table entries to be created for an on-link prefix where a local address has not yet been assigned to the network device. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [build] Update build system for Syslinux 6.xChristian Hesse2013-11-152-1/+12
| | | | | | | | | Syslinux 6.x places its files into a bios subdirectory, and requires that a ldlinux.c32 module be included within the ISO image. Add the relevant search paths for isolinux.bin, and include the file ldlinux.c32 within the ISO image if it exists. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [dhcpv6] Add basic support for stateful and stateless DHCPv6Michael Brown2013-11-144-5/+1207
| | | | | | | | | | | | Add support for the stateful and stateless variants of the DHCPv6 protocol. The resulting settings block is registered as "net<x>.dhcpv6", and DHCPv6 options can be obtained using e.g. "${net0.dhcpv6/23:ipv6}" to obtain the IPv6 DNS server address. IPv6 addresses obtained via stateful DHCPv6 are not yet applied to the network device. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [ipv6] Add "ipv6" setting typeMichael Brown2013-11-143-0/+70

* [base16] Fix comparison of signed and unsigned integersMichael Brown2013-11-141-1/+1
| | | | | | | gcc 4.7.1 fails to report this erroneous comparison unless assertions are enabled. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [pxe] Ensure cached DHCPACK is retrieved prior to network device creationMichael Brown2013-11-081-7/+12
| | | | | | | | | | | | | | | | | The retrieval of the cached DHCPACK and the creation of network devices are both currently scheduled as STARTUP_NORMAL. It is therefore possible that the cached DHCPACK will not be retrieved in time for cachedhcp_probe() to apply it to the relevant network device. Fix by retrieving the cached DHCPACK at initialisation time rather than at startup time. As an optimisation, an unclaimed cached DHCPACK can be freed immediately after the last network device has been created, rather than waiting until shutdown.

* [cmdline] Generate command option help text automaticallyMichael Brown2013-11-0722-75/+93
| | | | | | | Generate the command option help text automatically from the list of defined options. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [ipv6] Add IPv6 network device configuratorMichael Brown2013-11-072-28/+217
| | | | | | | | | | Include IPv6 within the generic network device configurator mechanism. The IPv6 configurator will send a router solicitation and wait for a router advertisement to be received. (As per RFC4861 section 6.3.7, we do this even if advertisements have been received prior to sending the router solicitation.) Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [dhcp] Remove obsolete dhcp() functionMichael Brown2013-11-052-25/+0Star
| | | | | | | All functionality provided by dhcp() has now been obviated by the more generic ifconf(). Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [dhcp] Add DHCP network device configuratorMichael Brown2013-11-051-0/+6
| | | | | | | Provide an interface to DHCP via the generic network device configurator mechanism. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [netdevice] Add generic concept of a network device configuratorMichael Brown2013-11-052-5/+282
| | | | | | | | | | | | | | iPXE supports multiple mechanisms for network device configuration: DHCPv4 for IPv4, FIP for FCoE, and SLAAC for IPv6. At present, DHCPv4 requires an explicit action (e.g. a "dhcp" command), FIP is initiated implicitly upon opening a network device, and SLAAC takes place whenever a RA happens to be received. Add a generic concept of a network device configurator, which provides a common interface to triggering configuration and to reporting the result of the configuration process.

* [cmdline] Allow "if<xxx>" commands to take optionsMichael Brown2013-11-056-63/+174
| | | | | | | Allow commands implemented using ifcommon_exec() to accept command-specific options. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [autoboot] Fix shell banner timeoutMichael Brown2013-11-051-1/+3
| | | | | | | | | | | Commit 5e1fa5c ("[parseopt] Add parse_timeout()") introduced a regression causing the shell banner timeout value (calculated in milliseconds) to be treated as a timer tick count, resulting in a timeout of approximately two minutes rather than the intended two seconds. Reported-by: Christian Hesse <list@eworm.de> Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [cmdline] Rewrite "sync" command to use monojob_wait()Michael Brown2013-11-015-25/+103

* [monojob] Report ongoing job status as overall return status on timeoutMichael Brown2013-11-011-2/+5
| | | | | | | | If a job times out then use the most recent ongoing error status reported via job_progress() (if available) as the overall return status. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [monojob] Add timeout parameter to monojob_wait()Michael Brown2013-11-018-18/+26
| | | | Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [job] Allow job_progress() to return an ongoing job status code, if knownMichael Brown2013-11-013-9/+20
| | | | | | | | Some background jobs have a meaningful ongoing status code (e.g. the current link status for a job waiting for a network link to come up). Allow this to be exposed via the job_progress() method. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [interface] Default to calling intf_restart() in response to intf_close()Michael Brown2013-11-011-2/+19
| | | | | | | | | If an object interface does not provide an intf_close() method, then default to calling intf_restart(). This allows static objects to safely ignore intf_close(), without needing to add code solely to ensure that the interface gets unplugged. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [netdevice] Make all net_driver methods optionalMichael Brown2013-11-016-72/+13Star
| | | | | | | | Most network upper-layer drivers do not implement all three methods (probe, notify, and remove). Save code by making all methods optional. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [parseopt] Add parse_timeout()Michael Brown2013-11-0112-27/+46
| | | | | | | | Parsing a timeout value (specified in milliseconds) into an internal timeout value measured in timer ticks is a common operation. Provide a parse_timeout() value to carry out this conversion automatically. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [ipv6] Add ndp_tx_router_solicitation() to send router solicitationsMichael Brown2013-10-255-37/+95

* [pxe] Always retrieve cached DHCPACK and apply to relevant network deviceMichael Brown2013-10-257-198/+239
| | | | | | | | | | | | When chainloading, always retrieve the cached DHCPACK packet from the underlying PXE stack, and apply it as the original contents of the "net<X>.dhcp" settings block. This allows cached DHCP settings to be used for any chainloaded iPXE binary (not just undionly.kkpxe). This change eliminates the undocumented "use-cached" setting. Issuing the "dhcp" command will now always result in a fresh DHCP request. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [ipv6] Automatically choose source for link-local and multicast destinationsMichael Brown2013-10-251-30/+34
| | | | | | | | When transmitting to a link-local or multicast destination address, use the network device's link-local address as the source address if no explicit source address has been specified. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [ipv6] Treat sin6_scope_id consistentlyMichael Brown2013-10-252-5/+5
| | | | | | | sin6_scope_id is never exposed outside of the local system, and so should be a native-endian quantity. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [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>
