* [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>
* [xsigo] Add support for Xsigo virtual Ethernet (XVE) EoIB devicesMichael Brown2016-03-092-0/+407
| | | | | | | | | Add support for EoIB devices as implemented by Xsigo. Based on the public (but out-of-tree) Linux kernel drivers at https://oss.oracle.com/git/?p=linux-uek.git;a=log;h=v4.1.12-32.2.1 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.

* [usb] Record USB device speed separately from current port speedMichael Brown2015-12-071-0/+2
| | | | | | | | | | | | | Record the speed of a USB device based on the port's speed at the time that the device was enabled. This allows us to remember the device's speed even after the device has been disconnected (and so the port's current speed has changed). In particular, this allows us to correctly identify the transaction translator for a low-speed or full-speed device after the device has been disconnected.

* [smsc95xx] Add driver for SMSC/Microchip LAN95xx USB Ethernet NICsMichael Brown2015-12-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Tested using QEMU and usbredir to expose the LAN9512 chip present on a Raspberry Pi. There is a known issue with the LAN9512: an extra two bytes are appended to every transmitted packet. These two bytes comprise: { 0x00, 0x08 } if packet length == 0 (mod 8) { CRC[0], 0x00 } if packet length == 7 (mod 8) { CRC[0], CRC[1] } otherwise The extra bytes are appended whether the Ethernet CRC is generated manually or added automatically by the hardware. The issue occurs with the Linux kernel driver as well as the iPXE driver. It appears to be an undocumented hardware errata. TCP/IP traffic is not affected, since the IP header length field causes the extraneous bytes to be discarded by the receiver. However, protocols that rely on the length of the Ethernet frame (such as FCoE or iPXE's "lotest" protocol) will be unusable on this hardware. Signed-off-by: Michael Brown <mcb30@ipxe.org>
