* [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.

* [parseopt] Add parse_timeout()Michael Brown2013-11-012-8/+6Star
| | | | | | | | 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>
* [pxe] Always retrieve cached DHCPACK and apply to relevant network deviceMichael Brown2013-10-251-5/+1Star
| | | | | | | | | | | | 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] Replace IPv6 stackMichael Brown2013-09-031-0/+58
| | | | | | | | | | | | | | | | 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).

* [lotest] Include sequence number within loopback test packetsMichael Brown2013-07-141-8/+18
| | | | | | | | Include a sequence number as the first four bytes of the loopback test packet payload. When a content mismatch occurs, this gives some information about the source of the mismatched packet. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [autoboot] Use next-server from filename's settings blockMichael Brown2013-06-241-14/+25
| | | | | | | | | | | Locate the settings block containing the filename, and search only that settings block for the next-server address. This avoids problems caused by misconfigured DHCP servers which provide a next-server address (often defaulting to the DHCP server's own IP address) even when not providing a filename.

* [ipoib] Expose Ethernet-compatible eIPoIB link-layer addresses and headersMichael Brown2012-08-311-10/+2Star
| | | | | | | | | | | | | Almost all clients of the raw-packet interfaces (UNDI and SNP) can handle only Ethernet link layers. Expose an Ethernet-compatible link layer to local clients, while remaining compatible with IPoIB on the wire. This requires manipulation of ARP (but not DHCP) packets within the IPoIB driver. This is ugly, but it's the only viable way to allow IPoIB devices to be driven via the raw-packet interfaces. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [crypto] Allow certificate chains to be long-lived data structuresMichael Brown2012-05-041-6/+12
| | | | | | | | | | | | | | | | | At present, certificate chain validation is treated as an instantaneous process that can be carried out using only data that is already in memory. This model does not allow for validation to include non-instantaneous steps, such as downloading a cross-signing certificate, or determining certificate revocation status via OCSP. Redesign the internal representation of certificate chains to allow chains to outlive the scope of the original source of certificates (such as a TLS Certificate record). Allow for certificates to be cached, so that each certificate needs to be validated only once. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [netdevice] Allow network device to update link state before checkingMichael Brown2012-04-211-0/+3
| | | | | | | | If the network interface has only just been opened (e.g. by the "dhcp" command) then we should allow at least one opportunity for the card to update the link state before testing it, to avoid false positives. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [image] Simplify image management commands and internal APIMichael Brown2012-03-252-46/+42Star
| | | | | | | | | | | | | | | | | | | | | | Remove the name, cmdline, and action parameters from imgdownload() and imgdownload_string(). These functions now simply download and return an image. Add the function imgacquire(), which will interpret a "name or URI string" parameter and return either an existing image or a newly downloaded image. Use imgacquire() to merge similar image-management commands that currently differ only by whether they take the name of an existing image or the URI of a new image to download. For example, "chain" and "imgexec" can now be merged. Extend imgstat and imgfree commands to take an optional list of images. Remove the arbitrary restriction on the length of image names.

* [image] Add concept of trusted imagesMichael Brown2012-03-221-0/+2
| | | | | | | | | | | | | | | | Trusted images may always be executed. Untrusted images may be executed only if the current image trust requirement allows untrusted images. Images can be marked as trusted using image_trust(), and marked as untrusted using image_untrust(). The current image trust requirement can be changed using image_set_trust(). It is possible to make the change permanent, in which case any future attempts to change the image trust requirement will fail. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [lotest] Accept non-loopback packets during testMichael Brown2011-12-081-58/+86
| | | | | | | | It can sometimes be awkward to prevent additional packets from being received during a loopback test. Allow such additional packets to be present without terminating the test. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [image] Eliminate the register_and_xxx_image() functionsMichael Brown2011-10-252-111/+25Star
| | | | | | | | All users of imgdownload() require registration of the image, so make registration an integral part of imgdownload() itself and simplify the "action" parameter to be one of image_select(), image_exec() et al. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [image] Simplify image managementMichael Brown2011-03-072-50/+4Star
| | | | | | | | | | | Refactor the {load,exec} image operations as {probe,exec}. This makes the probe mechanism cleaner, eliminates some forward declarations, avoids holding magic state in image->priv, eliminates the possibility of screwing up between the "load" and "exec" stages, and makes the documentation simpler since the concept of "loading" (as distinct from "executing") no longer needs to be explained.

* [autoboot] Allow a SAN boot as a fallback if a filename boot returnsMichael Brown2011-03-021-6/+23
| | | | | | | | | | | | | | | Currently, if both a filename and root-path are present, iPXE will hook the SAN device but will only attempt to boot from the filename. Change this behaviour so that both are attempted. Users who want to avoid booting from the SAN as a fallback can do so via the existing "skip-san-boot" setting. This allows for seamless deployment to a SAN target using Windows Deployment Services (and similar products). A user simply has to define the root-path option in DHCP and then use WDS to deploy the system. No further configuration should be required. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [autoboot] Tidy up output following NBP executionMichael Brown2011-03-021-1/+7

* [image] Allow download job to complete before acting upon imageMichael Brown2011-03-021-7/+11
| | | | | | | | | Allow the monojob controlling the download to complete before calling register_image() and friends. This allows the trailing "ok" from monojob.c to be printed before the image starts executing (and possibly printing output of its own). Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [autoboot] Connect SAN disk during a filename boot, if applicableMichael Brown2011-01-273-152/+233
| | | | | | | | | | | | | | | | | | | For performing installations direct to a SAN target, it can be very useful to hook a SAN disk and then proceed to perform a filename boot. For example, the user may wish to hook the (empty) SAN installation disk and then boot into the OS installer via TFTP. This provides an alternative mechanism to using "keep-san" and relying on the BIOS to fall through to boot from the installation media, which is unreliable on many BIOSes. When a root-path is specified in addition to a boot filename, attempt to hook the root-path as a SAN disk before booting from the specified filename. Since the root-path may be used for non-SAN purposes (e.g. an NFS root mount point), ignore the root-path if it contains a URI scheme that we do not support.
