* [shell] Enable "shell" command even when BANNER_TIMEOUT is zeroMichael Brown2017-08-011-0/+1
| | | | | | | | | | | Setting BANNER_TIMEOUT to zero removes the only symbol reference to shell.o, causing the "shell" command to become unavailable. Add SHELL_CMD in config/general.h (enabled by default) which will explicitly drag in shell.o regardless of the value of BANNER_TIMEOUT.

* [cloud] Add ability to retrieve Google Compute Engine metadataMichael Brown2017-01-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | For some unspecified "security" reason, the Google Compute Engine metadata server will refuse any requests that do not include the non-standard HTTP header "Metadata-Flavor: Google". Attempt to autodetect such requests (by comparing the hostname against "metadata.google.internal"), and add the "Metadata-Flavor: Google" header if applicable. Enable this feature in the CONFIG=cloud build, and include a sample embedded script allowing iPXE to boot from a script configured as metadata via e.g. # Create shared boot image make bin/ipxe.usb CONFIG=cloud EMBED=config/cloud/gce.ipxe # Configure per-instance boot script gcloud compute instances add-metadata <instance> \ --metadata-from-file ipxeboot=boot.ipxe Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [librm] Conditionalize the workaround for the Tivoli VMM's SSE garblingLaszlo Ersek2016-11-081-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 71560d1 ("[librm] Preserve FPU, MMX and SSE state across calls to virt_call()") added FXSAVE and FXRSTOR instructions to iPXE. In KVM virtual machines, these instructions execute fine as long as the host CPU supports the "unrestricted_guest" feature (that is, it can virtualize big real mode natively). On older host CPUs however, KVM has to emulate big real mode, and it currently doesn't implement FXSAVE emulation. Upstream QEMU rebuilt iPXE at commit 0418631 ("[thunderx] Fix compilation with older versions of gcc") which is a descendant of commit 71560d1 (see above). This was done in QEMU commit ffdc5a2 ("ipxe: update submodule from 4e03af8ec to 041863191"). The resultant binaries were bundled with the QEMU v2.7.0 release; see QEMU commit c52125a ("ipxe: update prebuilt binaries"). This distributed the iPXE workaround for the Tivoli VMM bug to a number of KVM users with old host CPUs, causing KVM emulation failures (guest crashes) for them while netbooting. Make the FXSAVE and FXRSTOR instructions conditional on a new feature test macro called TIVOLI_VMM_WORKAROUND. Define the macro by default. There is prior art for an assembly file including config/general.h: see arch/x86/prefix/romprefix.S. Also, TIVOLI_VMM_WORKAROUND seems to be a good fit for the "Obscure configuration options" section in config/general.h.

* [efi] Provide access to files stored on EFI filesystemsMichael Brown2016-03-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* [http] Rewrite HTTP core to support content encodingsMichael Brown2015-08-171-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Brown2015-06-251-0/+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.

* [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.)

* [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).

* [build] Allow for named configurations at build timeMichael Brown2014-08-201-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [romprefix] Do not fall back to hooking INT19 by defaultMichael Brown2011-05-171-0/+6
| | | | | | | | | | | | | | | | | | | | Several BIOSes (including most IBM BIOSes and many virtual machine BIOSes) do not provide detectable PnP support, but will use the BEV entry point for a PnP option ROM. On these semi-PnP BIOSes, iPXE will respond to the absence of detectable PnP support by hooking INT19, which disrupts the boot order. BIOSes that genuinely require hooking INT19 seem to be very rare nowadays. It may therefore be preferable to assume that the absence of detectable PnP support indicates a semi-PnP BIOS rather than a non-PnP BIOS. Change the default behaviour so that INT19 will never be hooked unless the compile-time option NONPNP_HOOK_INT19 is enabled. Leave the redundant PnP detection routine in-place to allow for debugging via the ROM banner line. Signed-off-by: Michael Brown <mcb30@ipxe.org>
