* [efi] Expose unused USB devices via EFI_USB_IO_PROTOCOLMichael Brown2015-09-141-0/+1
| | | | | | | 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 Brown2015-09-071-0/+1
| | | | | | | | | | | | | | | | | | | | | 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>
* [efi] Implement the EFI_PXE_BASE_CODE_PROTOCOLMichael Brown2015-09-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many UEFI NBPs expect to find an EFI_PXE_BASE_CODE_PROTOCOL installed in addition to the EFI_SIMPLE_NETWORK_PROTOCOL. Most NBPs use the EFI_PXE_BASE_CODE_PROTOCOL only to retrieve the cached DHCP packets. This implementation has been tested with grub.efi, shim.efi, syslinux.efi, and wdsmgfw.efi. Some methods (such as Discover() and Arp()) are not used by any known NBP and so have not (yet) been implemented. Usage notes for the tested bootstraps are: - grub.efi uses EFI_PXE_BASE_CODE_PROTOCOL only to retrieve the cached DHCP packet, and uses no other methods. - shim.efi uses EFI_PXE_BASE_CODE_PROTOCOL to retrieve the cached DHCP packet and to retrieve the next NBP via the Mtftp() method. If shim.efi was downloaded via HTTP (or other non-TFTP protocol) then shim.efi will blindly call Mtftp() with an HTTP URI as the filename: this allows the next NBP (e.g. grubx64.efi) to also be transparently retrieved by HTTP. shim.efi can also use the EFI_SIMPLE_FILE_SYSTEM_PROTOCOL to retrieve files previously loaded by "imgfetch" or similar commands in iPXE. The current implementation of shim.efi will use the EFI_SIMPLE_FILE_SYSTEM_PROTOCOL only if it does not find an EFI_PXE_BASE_CODE_PROTOCOL; this patch therefore prevents this usage of our EFI_SIMPLE_FILE_SYSTEM_PROTOCOL. This logic could be trivially reversed in shim.efi if needed. - syslinux.efi uses EFI_PXE_BASE_CODE_PROTOCOL only to retrieve the cached DHCP packet. Versions 6.03 and earlier have a bug which may cause syslinux.efi to attach to the wrong NIC if there are multiple NICs in the system (or if the UEFI firmware supports IPv6). - wdsmgfw.efi (ab)uses EFI_PXE_BASE_CODE_PROTOCOL to retrieve the cached DHCP packets, and to send and retrieve UDP packets via the UdpWrite() and UdpRead() methods. (This was presumably done in order to minimise the amount of benefit obtainable by switching to UEFI, by replicating all of the design mistakes present in the original PXE specification.) The EFI_DOWNGRADE_UX configuration option remains available for now, until this implementation has received more widespread testing. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [http] Rewrite HTTP core to support content encodingsMichael Brown2015-08-171-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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] Hold off watchdog timer while runningMichael Brown2015-08-031-0/+1
| | | | | | | | | | | | | | | | UEFI platforms may provide a watchdog timer, which will reboot the machine if an operating system takes more than five minutes to load. This can cause long-lived iPXE downloads (or interactive shell sessions) to unexpectedly reboot. Fix by resetting the watchdog timer every ten seconds while the iPXE main processing loop continues to run.

* [stp] Add support for detecting Spanning Tree Protocol non-forwarding portsMichael Brown2015-06-251-0/+1
| | | | | | | | | | | | | | | | | | 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.

* [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>

* [smsc75xx] Add driver for SMSC/Microchip LAN75xx USB Ethernet NICsMichael Brown2015-03-111-0/+1
| | | | | | | | | | | | | | | | | | | This driver is functional but any downloads via a TCP-based protocol tend to perform poorly. The 1Gbps Ethernet line rate is substantially higher than the 480Mbps (in practice around 280Mbps) provided by USB2, and the device has only 32kB of internal buffer memory. Our 256kB TCP receive window therefore rapidly overflows the RX FIFO, leading to multiple dropped packets (usually within the same TCP window) and hence a low overall throughput. Reducing the TCP window size so that the RX FIFO does not overflow greatly increases throughput, but is not a general-purpose solution. Further investigation is required to determine how other OSes (e.g. Linux) cope with this scenario. It is possible that implementing TCP SACK would provide some benefit.

* [efi] Add NII / UNDI driverMichael Brown2014-10-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | Some UEFI network drivers provide a software UNDI interface which is exposed via the Network Interface Identifier Protocol (NII), rather than providing a Simple Network Protocol (SNP). The UEFI platform firmware will usually include the SnpDxe driver, which attaches to NII and provides an SNP interface. The SNP interface is usually provided on the same handle as the underlying NII device. This causes problems for our EFI driver model: when efi_driver_connect() detaches existing drivers from the handle it will cause the SNP interface to be uninstalled, and so our SNP driver will not be able to attach to the handle. The platform firmware will eventually reattach the SnpDxe driver and may attach us to the SNP handle, but we have no way to prevent other drivers from attaching first. Fix by providing a driver which can attach directly to the NII protocol, using the software UNDI interface to drive the network device. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [efi] Wrap any images loaded by our wrapped imageMichael Brown2014-08-291-0/+1

Also show details of intercepted ExitBootServices() calls. When wrapping is used, exiting boot services will almost certainly fail, but this at least allows us to see when it happens.
