* [main] Add the "scriptlet" settingMichael Brown2011-03-281-1/+8
| | | | | | | | | | | | | | | | | | | A scriptlet is a single iPXE command that can be stored in non-volatile option storage and used to override the default "autoboot" behaviour without having to reflash the iPXE image. For example, a scriptlet could contain autoboot || reboot to instruct iPXE to reboot the system if booting fails. Unlike an embedded image, the presence of a scriptlet does not inhibit the initial "Press Ctrl-B..." prompt. This allows the user to recover from setting a faulty scriptlet.

* [settings] Display canonical setting name in output of "show" commandMichael Brown2011-03-221-1/+3
| | | | | | | | | | | | | | | | | | Enable the "show" command to display the full, canonicalised name of the fetched setting. For example: iPXE> show mac net0/mac:hex = 52:54:00:12:34:56 iPXE> dhcp && show ip DHCP (net0 52:54:00:12:34:56)... ok net0.dhcp/ip:ipv4 = 10.0.0.168 iPXE> show net0/6 net0.dhcp/dns:ipv4 = 10.0.0.6 Inspired-by: Glenn Brown <glenn@myri.com> Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [settings] Formalise notion of setting applicabilityMichael Brown2011-03-224-4/+90
| | | | | | | | | | | | | | | Expose a function setting_applies() to allow a caller to determine whether or not a particular setting is applicable to a particular settings block. Restrict DHCP-backed settings blocks to accepting only DHCP-based settings. Restrict network device settings blocks to accepting only DHCP-based settings and network device-specific settings such as "mac".

* [build] Avoid spurious unused-but-set-variable warnings in gcc 4.6Michael Brown2011-03-161-1/+2

* [efi] Mark SNP devices as children of EFI PCI deviceMichael Brown2011-03-151-0/+6
| | | | | | | | | | | | | Re-open the EFI_PCI_IO_PROTOCOL specifying an Attributes value of EFI_OPEN_PROTOCOL_BY_CHILD_CONTROLLER. This causes the SNP devices to be marked as children of the EFI PCI device (as shown in the "devtree" command). On at least one IBM blade system, this is required in order to have the relevant drivers automatically attach to the SNP controller at device creation time.

* [image] Move the register_and_{select|boot}_image() functions to imgmgmt.cMichael Brown2011-03-092-2/+2
| | | | | | | | These functions are used only as the "action" parameters to imgdownload() or imgfetch(), and so belong in imgmgmt.c rather than image.c Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [prefix] Allow iPXE's own command line to be executed as a scriptMichael Brown2011-03-072-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | Some prefixes (e.g. .lkrn) allow a command line to be passed in to iPXE. At present, this command line is ignored. If a command line is provided, treat it as an embedded script (without an explicit "#!ipxe" magic marker). This allows for patterns of invocation such as title iPXE kernel /boot/ipxe.lkrn dhcp && \ sanboot iscsi:10.0.4.1::::iqn.2010-04.org.ipxe.dolphin:storage Here GRUB is instructed to load ipxe.lkrn with an embedded script equivalent to #!ipxe dhcp sanboot iscsi:10.0.4.1::::iqn.2010-04.org.ipxe.dolphin:storage This can be used to effectively vary the embedded script without having to rebuild ipxe.lkrn.

* [image] Simplify image managementMichael Brown2011-03-073-47/+51
| | | | | | | | | | | 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. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [parseopt] Refer to online documentation for command helpMichael Brown2011-03-041-6/+4Star
| | | | | | | | | | The online documentation (e.g. http://ipxe.org/cmd/ifopen), though not yet complete, is far more comprehensive than could be provided within the iPXE binary. Save around 200 bytes (compressed) by removing the command descriptions from the interactive help, and instead referring users directly to the web page describing the relevant command.

* [iscsi] Change default initiator IQNMichael Brown2011-03-031-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The default initiator IQN is "iqn.2000-09.org.etherboot:UNKNOWN". This is problematic for two reasons: a) the etherboot.org domain (and hence the associated IQN namespace) is not under the control of the iPXE project, and b) some targets (correctly) refuse to allow concurrent connections from different initiators using the same initiator IQN. Solve both problems by changing the default initiator IQN to be iqn.2010-04.org.ipxe:<hostname> if a hostname is set, or iqn.2010-04.org.ipxe:<uuid> if no hostname is set. Explicit initiator IQNs set via DHCP option 203 are not affected by this change. Unfortunately, this change is likely to break some existing configurations, where ACL rules have been put in place referring to the old default initiator IQN. Users may need to update ACLs, or force the use of the old IQN using an iPXE script line such as set initiator-iqn iqn.2000-09.org.etherboot:UNKNOWN or a dhcpd.conf option such as option iscsi-initiator-iqn "iqn.2000-09.org.etherboot:UNKNOWN" Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [bofm] Allow garbage collection of BOFM code in non-BOFM buildsMichael Brown2011-03-031-1/+10

* [bofm] Add offline BOFM test facilityMichael Brown2011-03-031-0/+1

* [image] Allow download job to complete before acting upon imageMichael Brown2011-03-022-3/+2Star

* [iscsi] Accept NOP-In PDUs sent by the targetMichael Brown2011-02-241-0/+34
| | | | | | | | | | | | Some iSCSI targets (observed with a Synology DS207+ NAS) send unsolicited NOP-Ins to the initiator. RFC 3720 is remarkably unclear and possibly self-contradictory on how NOPs are supposed to work, but it seems as though we can legitimately just ignore any unsolicited NOP-In PDU.

* [efi] Allow EFI to control PCI bus enumerationMichael Brown2011-02-173-1/+89
| | | | | | | | | | | | | | EFI performs its own PCI bus enumeration. Respect this, and start controlling devices only when instructed to do so by EFI. As a side benefit, we should now correctly create multiple SNP instances for multi-port devices. This should also fix the problem of failing to enumerate devices because the PCI bridges have not yet been enabled at the time the iPXE driver is loaded. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [autoboot] Connect SAN disk during a filename boot, if applicableMichael Brown2011-01-273-3/+8
| | | | | | | | | | | | | | | | | | | 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.
