* [efi] Expose unused USB devices via EFI_USB_IO_PROTOCOLMichael Brown2015-09-143-5/+23
| | | | | | | 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>
* [efi] Add a USB host controller driver based on EFI_USB_IO_PROTOCOLMichael Brown2015-09-072-0/+4
| | | | | | | | | | | | | | | | | | | | | Allow iPXE to coexist with other USB device drivers, by attaching to the EFI_USB_IO_PROTOCOL instances provided by the UEFI platform firmware. The EFI_USB_IO_PROTOCOL is an unsurprisingly badly designed abstraction of a USB device. The poor design choices intrinsic in the UEFI specification prevent efficient operation as a network device, with the result that devices operated using the EFI_USB_IO_PROTOCOL operate approximately two orders of magnitude slower than devices operated using our native EHCI or xHCI host controller drivers. Since the performance is so abysmally slow, and since the underlying problems are due to fundamental architectural mistakes in the UEFI specification, support for the EFI_USB_IO_PROTOCOL host controller driver is left as disabled by default. Users are advised to use the native iPXE host controller drivers instead. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [http] Rewrite HTTP core to support content encodingsMichael Brown2015-08-174-0/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [efi] Allow user experience to be downgradedMichael Brown2015-07-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | iPXE does not currently provide EFI_PXE_BASE_CODE_PROTOCOL: this causes failures when chainloading bootloaders such as shim.efi which assume that this protocol will be present. Provide the ability to work around these problems via the build configuration option EFI_DOWNGRADE_UX. If this option is enabled, then we will not install our usual EFI_LOAD_FILE_PROTOCOL implementation, thereby allowing the platform firmware to install its own EFI_PXE_BASE_CODE_PROTOCOL implementation on top of our EFI_SIMPLE_NETWORK_PROTOCOL handle. A somewhat major side-effect of this workaround is that almost all iPXE features will be disabled. This configuration option will be removed in future when support for EFI_PXE_BASE_CODE_PROTOCOL is added.

* [stp] Add support for detecting Spanning Tree Protocol non-forwarding portsMichael Brown2015-06-252-0/+4
| | | | | | | | | | | | | | | | | | A fairly common end-user problem is that the default configuration of a switch may leave the port in a non-forwarding state for a substantial length of time (tens of seconds) after link up. This can cause iPXE to time out and give up attempting to boot. We cannot force the switch to start forwarding packets sooner, since any attempt to send a Spanning Tree Protocol bridge PDU may cause the switch to disable our port (if the switch happens to have the Bridge PDU Guard feature enabled for the port). For non-ancient versions of the Spanning Tree Protocol, we can detect whether or not the port is currently forwarding and use this to inform the network device core that the link is currently blocked.

* [int13con] Add basic ability to log to a local disk via INT 13Michael Brown2015-05-192-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | Several popular public cloud providers do not provide any sensible mechanism for obtaining debug output from an OS which is failing to boot. For example, Amazon EC2 provides the "Get System Log" facility, which occasionally deigns to report a random subset of the characters emitted via the VM's serial port, but usually returns only a blank screen. (Amazingly, this is still superior to the debugging facilities provided by Azure.) Work around these shortcomings by adding a console type which sends output to a magically detected raw disk partition, and including such a partition within any iPXE .usb-format image. To use this facility: - build an iPXE .usb image with CONSOLE_INT13 enabled - boot the cloud VM from this image - after the boot fails, attach the VM's boot disk to a second VM - from this second VM, use "less -f -R /dev/sdb3" (or similar) to view the iPXE output.

* [usb] Add basic support for USB keyboardsMichael Brown2015-05-123-0/+14
| | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | The "vram" setting returns the (Base64-encoded) contents of video RAM, and can be used to capture a screenshot. For example: after running memtest.0 and encountering an error, the output can be captured and sent to a remote server for later diagnosis: #!ipxe chain -a http://server/memtest.0 && goto ok || goto bad :bad params param errno ${errno} param vram ${vram} chain -a http://server/report.php##params :ok Inspired-by: Christian Nilsson <nikize@gmail.com> Originally-implemented-by: Christian Nilsson <nikize@gmail.com> Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [romprefix] Allow autoboot device filter to be disabledMichael Brown2015-04-131-0/+1
| | | | | | | | | | | | | | | | | Our current behaviour when booting as a ROM is to autoboot only from devices which are attached via the PCI bus:dev.fn address passed to the ROM's initialisation vector. Add a build configuration option AUTOBOOT_ROM_FILTER (enabled by default) to control this behaviour. This allows for ROMs to be built which will attempt to boot from any detected device, even if not attached via the original PCI bus:dev.fn address. (This is particularly useful when building combined EHCI/xHCI ROMs for USB network boot, since the BIOS may request a boot via the EHCI controller but the xHCI driver will reroute the root hub ports to the xHCI controller.)

* [build] Fix the REQUIRE_SYMBOL mechanismMichael Brown2015-03-058-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | At some point in the past few years, binutils became more aggressive at removing unused symbols. To function as a symbol requirement, a relocation record must now be in a section marked with @progbits and must not be in a section which gets discarded during the link (either via --gc-sections or via /DISCARD/). Update REQUIRE_SYMBOL() to generate relocation records meeting these criteria. To minimise the impact upon the final binary size, we use existing symbols (specified via the REQUIRING_SYMBOL() macro) as the relocation targets where possible. We use R_386_NONE or R_X86_64_NONE relocation types to prevent any actual unwanted relocation taking place. Where no suitable symbol exists for REQUIRING_SYMBOL() (such as in config.c), the macro PROVIDE_REQUIRING_SYMBOL() can be used to generate a one-byte-long symbol to act as the relocation target. If there are versions of binutils for which this approach fails, then the fallback will probably involve killing off REQUEST_SYMBOL(), redefining REQUIRE_SYMBOL() to use the current definition of REQUEST_SYMBOL(), and postprocessing the linked ELF file with something along the lines of "nm -u | wc -l" to check that there are no undefined symbols remaining.

* [dhcp] Extract timing parameters out to config/dhcp.hAlex Williamson2015-02-251-0/+87
| | | | | | | | | | | | | | iPXE uses DHCP timeouts loosely based on values recommended by the specification, but often abbreviated to reduce timeouts for reliable and/or simple network topologies. Extract the DHCP timing parameters to config/dhcp.h and document them. The resulting default iPXE behavior is exactly the same, but downstreams are now afforded the opportunity to implement spec-compliant behavior via config file overrides.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow named configurations to be specified via the CONFIG=... build parameter. For headers in config/*.h which support named configurations, the following files will be included when building with CONFIG=<name>: - config/defaults/<platform>.h (e.g. config/defaults/pcbios.h) - config/<header>.h - config/<name>/<header>.h (only if the directory config/<name> exists) - config/local/<header>.h (autocreated if necessary) - config/local/<name>/<header>.h (autocreated if necessary) This mechanism allows for predefined named configurations to be checked in to the source tree, as a directory config/<name> containing all of the required header files. The mechanism also allows for users to define multiple local configurations, by creating header files in the directory config/local/<name>. Note that the config/*.h files which are used only to configure internal iPXE APIs (e.g. config/ioapi.h) cannot be modified via a named configuration. This avoids rebuilding the entire iPXE codebase whenever switching to a different named configuration.

* [romprefix] Allow ROM banner timeout to be configured independentlyAlex Williamson2014-03-031-4/+15
| | | | | | | | | | | | | | | | | iPXE currently prints a "Press Ctrl-B" banner twice: once when the ROM is first called for initialisation and again if we attempt to boot from the ROM. This slows boot, especially when the NIC is not the primary boot device. Tools such as libguestfs make use of QEMU VMs for performing maintenance on disk images and may make use of NICs in the VM for network support. If iPXE introduces a static init-time delay, that directly translates to increased runtime for the tools. Fix by allowing the ROM banner timeout to be configured independently of the main banner timeout.
