* [ocsp] Accept response certID with missing hashAlgorithm parametersMichael Brown2019-03-101-2/+2
| | | | | | | | | | | | | | | | | | One of the design goals of ASN.1 DER is to provide a canonical serialization of a data structure, thereby allowing for equality of values to be tested by simply comparing the serialized bytes. Some OCSP servers will modify the request certID to omit the optional (and null) "parameters" portion of the hashAlgorithm. This is arguably legal but breaks the ability to perform a straightforward bitwise comparison on the entire certID field between request and response. Fix by comparing the OID-identified hashAlgorithm separately from the remaining certID fields. Originally-fixed-by: Thilo Fromm <Thilo@kinvolk.io> Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [tls] Support stateful session resumptionMichael Brown2019-02-211-2/+29
| | | | | | | | | | | | | Record the session ID (if any) provided by the server and attempt to reuse it for any concurrent connections to the same server. If multiple connections are initiated concurrently (e.g. when using PeerDist) then defer sending the ClientHello for all but the first connection, to allow time for the first connection to potentially obtain a session ID (and thereby speed up the negotiation for all remaining connections).

* [efi] Blacklist the Dell Ip4ConfigDxe driverMichael Brown2019-02-192-0/+14
| | | | | | | | | | | | | | | | | | On a Dell OptiPlex 7010, calling DisconnectController() on the LOM device handle will lock up the system. Debugging shows that execution is trapped in an infinite loop that is somehow trying to reconnect drivers (without going via ConnectController()). The problem can be reproduced in the UEFI shell with no iPXE code present, by using the "disconnect" command. Experimentation shows that the only fix is to unload (rather than just disconnect) the "Ip4ConfigDxe" driver. Add the concept of a blacklist of UEFI drivers that will be automatically unloaded when iPXE runs as an application, and add the Dell Ip4ConfigDxe driver to this blacklist.

* [mii] Separate concepts of MII interface and MII deviceMichael Brown2018-04-191-19/+48
| | | | | | | | | | | | | We currently have no generic concept of a PHY address, since all existing implementations simply hardcode the PHY address within the MII access methods. A bit-bashing MII interface will need to be provided with an explicit PHY address in order to generate the correct waveform. Allow for this by separating out the concept of a MII device (i.e. a specific PHY address attached to a particular MII interface). Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [tls] Rename tls_session to tls_connectionMichael Brown2018-03-241-2/+2
| | | | | | | | | | | | In TLS terminology a session conceptually spans multiple individual connections, and essentially represents the stored cryptographic state (master secret and cipher suite) required to establish communication without going through the certificate and key exchange handshakes. Rename tls_session to tls_connection in order to make the name tls_session available to represent the session state. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [rng] Use fixed-point calculations for min-entropy quantitiesMichael Brown2018-03-204-9/+29
| | | | | | | | | | | | | | We currently perform various min-entropy calculations using build-time floating-point arithmetic. No floating-point code ends up in the final binary, since the results are eventually converted to integers and asserted to be compile-time constants. Though this mechanism is undoubtedly cute, it inhibits us from using "-mno-sse" to prevent the use of SSE registers by the compiler. Fix by using fixed-point arithmetic instead.

* [ocsp] Allow OCSP checks to be disabledMichael Brown2018-03-181-0/+12

| | | | | | | | | | | | Mark the link as blocked if the LACP partner is not reporting itself as being in sync, collecting, and distributing. This matches the behaviour for STP: we mark the link as blocked if we detect that the switch is actively blocking traffic, in order to extend the DHCP discovery period and so prevent boot failures on switches that take an excessively long time to enable ports.

* [hyperv] Do not steal ownership from the Gen 2 UEFI firmwareMichael Brown2017-07-281-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | We must not steal ownership from the Gen 2 UEFI firmware, since doing so will cause an immediate system crash (most likely in the form of a reboot). This problem was masked before commit a0f6e75 ("[hyperv] Do not fail if guest OS ID MSR is already set"), since prior to that commit we would always fail if we found any non-zero guest OS identity. We now accept a non-zero previous guest OS identity in order to allow for situations such as chainloading from iPXE to another iPXE, and as a prerequisite for commit b91cc98 ("[hyperv] Cope with Windows Server 2016 enlightenments"). A proper fix would be to reverse engineer the UEFI protocols exposed within the Hyper-V Gen 2 firmware and use these to bind to the VMBus device representing the network connection, (with the native Hyper-V driver moved to become a BIOS-only feature). As an interim solution, fail to initialise the native Hyper-V driver if we detect the guest OS identity known to be used by the Gen 2 UEFI firmware. This will cause the standard all-drivers build (ipxe.efi) to fall back to using the SNP driver. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [build] Fix use of inline assembly on GCC 4.8 ARM64 buildsMichael Brown2017-07-281-2/+2
| | | | | | | | | | | | | | | | The inline assembly used in include/errno.h to generate the einfo blocks requires the ability to generate an immediate constant with no immediate-value prefix (such as the dollar sign for x86 assembly). We currently achieve this via the undocumented "%c0" form of operand. This causes an "invalid operand prefix" error on GCC 4.8 for ARM64 builds. Fix by switching to the equally undocumented "%a0" form of operand, which appears to work correctly on all tested versions of GCC. Reported-by: Benjamin S.

* [usb] Use non-zero language ID to retrieve stringsMichael Brown2017-07-031-0/+6
| | | | | | | | | | | | We currently use a zero language ID to retrieve strings such as the ECM/NCM MAC address. This works on most hardware devices, but is known to fail on some software emulated CDC-NCM devices. Fix by using the first supported language ID, falling back to English (0x0409) if any error occurs when fetching the list of supported languages. This matches the behaviour of the Linux kernel.

Numeric values are returned in reverse byte order, since ACPI numeric values are usually little-endian. For example: ${acpi/0x41504943.0.0.0.0} - entire MADT table in raw hex ${acpi/0x41504943.0.0.0x0a.6:string} - MADT table OEM ID ${acpi/0x41504943.0.0.0x24.4:uint32} - local APIC address Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [hyperv] Cope with Windows Server 2016 enlightenmentsMichael Brown2017-04-282-0/+29
| | | | | | | | | | | | | | | | | | | | | | | An "enlightened" external bootloader (such as Windows Server 2016's winload.exe) may take ownership of the Hyper-V connection before all INT 13 operations have been completed. When this happens, all VMBus devices are implicitly closed and we are left with a non-functional network connection. Detect when our Hyper-V connection has been lost (by checking the SynIC message page MSR). Reclaim ownership of the Hyper-V connection and reestablish any VMBus devices, without disrupting any existing iPXE state (such as IPv4 settings attached to the network device). Windows Server 2016 will not cleanly take ownership of an active Hyper-V connection. Experimentation shows that we can quiesce by resetting only the SynIC message page MSR; this results in a successful SAN boot (on a Windows 2012 R2 physical host). Choose to quiesce by resetting (almost) all MSRs, in the hope that this will be more robust against corner cases such as a stray synthetic interrupt occurring during the handover.

* [block] Provide abstraction to allow system to be quiescedMichael Brown2017-04-261-0/+31
| | | | | | | | | | | | | | | | | | When performing a SAN boot via INT 13, there is no way for the operating system to indicate that it has finished using the INT 13 SAN device. We therefore have no opportunity to clean up state before the loaded operating system's native drivers take over. This can cause problems when booting Windows, which tends not to be forgiving of unexpected system state. Windows will typically write a flag to the SAN device as the last action before transferring control to the native drivers. We can use this as a heuristic to bring the system to a quiescent state (without performing a full shutdown); this provides us an opportunity to temporarily clean up state that could otherwise prevent a successful Windows boot.
