* [efi] Use a timer event to generate the currticks() timerMichael Brown2016-05-042-302/+18Star
| | | | | | | | | | | | | | We currently use the EFI_CPU_ARCH_PROTOCOL's GetTimerValue() method to generate the currticks() timer, calibrated against a 1ms delay from the boot services Stall() method. This does not work on ARM platforms, where GetTimerValue() is an empty stub which just returns EFI_UNSUPPORTED. Fix by instead creating a periodic timer event, and using this event to increment a current tick counter. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [virtio] Add virtio 1.0 PCI supportLadi Prosek2016-04-153-1/+153
| | | | | | | | | | | | This commit adds support for driving virtio 1.0 PCI devices. In addition to various helpers, a number of vpm_ functions are introduced to be used instead of their legacy vp_ counterparts when accessing virtio 1.0 (aka modern) devices.

| | | | | | | | | | Virtio 1.0 introduces new constants and data structures, common to all devices as well as specific to virtio-net.

* [pci] Add pci_find_next_capability()Ladi Prosek2016-04-151-0/+2
| | | | | | | | | | | | | | | | | PCI devices may support more capabilities of the same type (for example PCI_CAP_ID_VNDR) and there was no way to discover all of them. This commit adds a new API pci_find_next_capability which provides this functionality. It would typically be used like so: for (pos = pci_find_capability(pci, PCI_CAP_ID_VNDR); pos > 0; pos = pci_find_next_capability(pci, pos, PCI_CAP_ID_VNDR)) { ... } Signed-off-by: Ladi Prosek <lprosek@redhat.com> Reviewed-by: Michael S.

* [int13] Allow default drive to be specified via "san-drive" settingMichael Brown2016-03-221-3/+3
| | | | | | | | | | | The DHCP option 175.189 has been defined (by us) since 2006 as containing the drive number to be used for a SAN boot, but has never been automatically used as such by iPXE.

* [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>

* [build] Allow assembler section type character to vary by architectureMichael Brown2016-03-132-4/+15
| | | | | | | | | | | | | | | On some architectures (such as ARM) the "@" character is used as a comment delimiter. A section type argument such as "@progbits" therefore becomes "%progbits". This is further complicated by the fact that the "%" character has special meaning for inline assembly when input or output operands are used, in which cases "@progbits" becomes "%%progbits". Allow the section type character(s) to be defined via Makefile variables. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [arp] Validate length of ARP packetMichael Brown2016-03-121-0/+10
| | | | | | | | | | | | There is no practical way to generate an underlength ARP packet since an ARP packet is always padded up to the minimum Ethernet frame length (or dropped by the receiving Ethernet hardware if incorrectly padded), but the absence of an explicit check causes warnings from some analysis tools. Fix by adding an explicit check on the I/O buffer length. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [crypto] Allow for zero-length ASN.1 cursorsMichael Brown2016-03-111-2/+14
| | | | | | | | | | | | | The assumption in asn1_type() that an ASN.1 cursor will always contain a type byte is incorrect. A cursor that has been cleanly invalidated via asn1_invalidate_cursor() will contain a type byte, but there are other ways in which to arrive at a zero-length cursor. Fix by explicitly checking the cursor length in asn1_type(). This allows asn1_invalidate_cursor() to be reduced to simply zeroing the length field. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [eoib] Support non-FullMember gateway devicesMichael Brown2016-03-091-0/+22
| | | | | | | | | | | | | Some EoIB implementations utilise an EoIB-to-Ethernet gateway device that does not perform a FullMember join to the multicast group for the EoIB broadcast domain. This has various exciting side-effects, such as requiring every EoIB node to send every broadcast packet twice. As an added bonus, the gateway may also break the EoIB MAC address to GID mapping protocol by sending Ethernet-sourced packets from the wrong QPN. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [eoib] Allow the multicast group to be forcefully createdMichael Brown2016-03-091-0/+21
| | | | | | | | | | | | | Some EoIB implementations require each individual EoIB node to create the multicast group for the EoIB broadcast domain. It is left as an exercise for the interested reader to determine how such an implementation might ever allow the parameters of such a multicast group to be changed without requiring a simultaneous upgrade of every driver on every operating system on every machine currently attached to the fabric.

* [eoib] Add Ethernet over Infiniband (EoIB) driverMichael Brown2016-03-092-0/+61
| | | | | | | | | | | | | | | | | | | | EoIB is a fairly simple protocol in which raw Ethernet frames (excluding the CRC) are encapsulated within Infiniband Unreliable Datagrams, with a four-byte fixed EoIB header (which conveys no actual information). The Ethernet broadcast domain is provided by a multicast group, similar to the IPoIB IPv4 multicast group. The mapping from Ethernet MAC addresses to Infiniband address vectors is achieved by snooping incoming traffic and building a peer cache which can then be used to map a MAC address into a port GID. The address vector is completed using a path record lookup, as for IPoIB. Note that this requires every packet to include a GRH. Add basic support for EoIB devices. This driver is substantially derived from the IPoIB driver. There is currently no mechanism for automatically creating EoIB devices. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [ipoib] Resimplify test for received broadcast packetsMichael Brown2016-03-081-0/+3
| | | | | | | | | | | | Commit e62e52b ("[ipoib] Simplify test for received broadcast packets") relies upon the multicast LID being present in the destination address vector as passed to ipoib_complete_recv(). Unfortunately, this information is not present in many Infiniband devices' completion queue entries. Fix by testing instead for the presence of a multicast GID.
