* [efi] Provide access to files stored on EFI filesystemsMichael Brown2016-03-141-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Provide access to local files via the "file://" URI scheme. There are three syntaxes: - An opaque URI with a relative path (e.g. "file:script.ipxe"). This will be interpreted as a path relative to the iPXE binary. - A hierarchical URI with a non-network absolute path (e.g. "file:/boot/script.ipxe"). This will be interpreted as a path relative to the root of the filesystem from which the iPXE binary was loaded. - A hierarchical URI with a network path in which the authority is a volume label (e.g. "file://bootdisk/script.ipxe"). This will be interpreted as a path relative to the root of the filesystem with the specified volume label. Note that the potentially desirable shell mappings (e.g. "fs0:" and "blk0:") are concepts internal to the UEFI shell binary, and do not seem to be exposed in any way to external executables. The old EFI_SHELL_PROTOCOL (which did provide access to these mappings) is no longer installed by current versions of the UEFI shell. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [efi] Expose unused USB devices via EFI_USB_IO_PROTOCOLMichael Brown2015-09-141-0/+5
| | | | | | | Allow the UEFI platform firmware to provide drivers for unrecognised devices, by exposing our own implementation of EFI_USB_IO_PROTOCOL. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [http] Rewrite HTTP core to support content encodingsMichael Brown2015-08-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rewrite the HTTP core to allow for the addition of arbitrary content encoding mechanisms, such as PeerDist and gzip. The core now exposes http_open() which can be used to create requests with an explicitly selected HTTP method, an optional requested content range, and an optional request body. A simple wrapper provides the preexisting behaviour of creating either a GET request or an application/x-www-form-urlencoded POST request (if the URI includes parameters). The HTTP SAN interface is now implemented using the generic block device translator. Individual blocks are requested using http_open() to create a range request. Server connections are now managed via a connection pool; this allows for multiple requests to the same server (e.g. for SAN blocks) to be completely unaware of each other. Repeated HTTPS connections to the same server can reuse a pooled connection, avoiding the per-connection overhead of establishing a TLS session (which can take several seconds if using a client certificate). Support for HTTP SAN booting and for the Basic and Digest authentication schemes is now optional and can be controlled via the SANBOOT_PROTO_HTTP, HTTP_AUTH_BASIC, and HTTP_AUTH_DIGEST build configuration options in config/general.h.

* [usb] Add basic support for USB keyboardsMichael Brown2015-05-121-0/+1
| | | | | | | | | | | | When USB network card drivers are used, the BIOS' legacy USB capability is necessarily disabled since there is no way to share the host controller between the BIOS and iPXE. This currently results in USB keyboards becoming non-functional in USB-enabled builds of iPXE. Fix by adding basic support for USB keyboards, enabled by default in iPXE builds which include USB support. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [legal] Relicense files under GPL2_OR_LATER_OR_UBDLMichael Brown2015-03-021-1/+1
| | | | | | | | | | These files cannot be automatically relicensed by util/relicense.pl since they either contain unusual but trivial contributions (such as the addition of __nonnull function attributes), or contain lines dating back to the initial git revision (and so require manual knowledge of the code's origin).

| | | | | | | | | Abstract out the ability to reboot the system to a separate reboot() function (with platform-specific implementations), add an EFI implementation, and make the existing "reboot" command available under EFI. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [efi] Default to using raw x86 I/OMichael Brown2012-07-171-1/+1
| | | | | | | | | | The EFI_CPU_IO_PROTOCOL is not available on all EFI platforms. In particular, it is not available under OVMF, as used for qemu. Since the EFI_CPU_IO_PROTOCOL is an abomination of unnecessary complexity, banish it and use raw I/O instead. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [cmdline] Add "cpuid" commandMichael Brown2012-06-071-0/+1

* [comboot] Remove COMBOOT image support by defaultMichael Brown2012-03-291-1/+0Star
| | | | | | | | | | | iPXE's support for COMBOOT images is now quite outdated; it has not kept up to date with changes in the COMBOOT API. The primary use for COMBOOT seems to be for menuing support. Now that we have native iPXE script-based menus, COMBOOT support can be gracefully retired (with immense thanks to Daniel Verkamp for having successfully implemented such an ambitious feature many years ago).

* [rng] Add RTC-based entropy sourceMichael Brown2012-02-281-1/+1
| | | | | | | | | | | The RTC-based entropy source uses the nanosecond-scale CPU TSC to measure the time between two 1kHz interrupts generated by the CMOS RTC. In a physical machine these clocks are driven from independent crystals, resulting in some observable clock drift. In a virtual machine, the CMOS RTC is typically emulated using host-OS constructions such as SIGALRM. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [rng] Add ANS X9.82 Approved Source of Entropy InputMichael Brown2012-02-213-0/+3
| | | | | | | | | | | | | | | | ANS X9.82 specifies several Approved Sources of Entropy Input (SEI). One such SEI uses an entropy source as the Source of Entropy Input, condensing each entropy source output after each GetEntropy call. This can be implemented relatively cheaply in iPXE and avoids the need to allocate potentially very large buffers. (Note that the terms "entropy source" and "Source of Entropy Input" are not synonyms within the context of ANS X9.82.) Use the iPXE API mechanism to allow entropy sources to be selected at compilation time. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [block] Replace gPXE block-device API with an iPXE asynchronous interfaceMichael Brown2010-09-143-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The block device interface used in gPXE predates the invention of even the old gPXE data-transfer interface, let alone the current iPXE generic asynchronous interface mechanism. Bring this old code up to date, with the following benefits: o Block device commands can be cancelled by the requestor. The INT 13 layer uses this to provide a global timeout on all INT 13 calls, with the result that an unexpected passive failure mode (such as an iSCSI target ACKing the request but never sending a response) will lead to a timeout that gets reported back to the INT 13 user, rather than simply freezing the system. o INT 13,00 (reset drive) is now able to reset the underlying block device. INT 13 users, such as DOS, that use INT 13,00 as a method for error recovery now have a chance of recovering. o All block device commands are tagged, with a numerical tag that will show up in debugging output and in packet captures; this will allow easier interpretation of bug reports that include both sources of information. o The extremely ugly hacks used to generate the boot firmware tables have been eradicated and replaced with a generic acpi_describe() method (exploiting the ability of iPXE interfaces to pass through methods to an underlying interface). The ACPI tables are now built in a shared data block within .bss16, rather than each requiring dedicated space in .data16. o The architecture-independent concept of a SAN device has been exposed to the iPXE core through the sanboot API, which provides calls to hook, unhook, boot, and describe SAN devices. This allows for much more flexible usage patterns (such as hooking an empty SAN device and then running an OS installer via TFTP). Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [linux] Add uaccessPiotr Jaroszyński2010-08-191-0/+1
| | | | | | | | | | | | | | | Add user access API for linux. On linux userspace virtual == user == phys addresses. Physical addresses also being the same is wrong, but there is no general way of converting userspace addresses to physical as what appears to be contiguous in userspace is physically fragmented. Currently only the DMA memory is special-cased, but its conversion to bus addresses is done in phys_to_bus. This is known to break virtio as it is passing phys addresses to the virtual device.

* [config] Make PXE stack a compile-time optionJoshua Oreman2010-01-201-0/+2
| | | | | | | | | | For extremely tight space requirements and specific applications, it is sometimes desirable to create gPXE images that cannot provide the PXE API functionality to client programs. Add a configuration header option, PXE_STACK, that can be removed to remove this stack. Also add PXE_MENU to control the PXE boot menu, which most uses of gPXE do not need.
