* [build] Work around bug in gcc >= 4.8Michael Brown2013-09-256-20/+35
| | | | | | | | | | | | | Commit 238050d ("[build] Work around bug in gcc >= 4.8") works around one instance of a bug in recent versions of gcc, in which "ebp" cannot be specified within an asm clobber list. Some versions of gcc seem to exhibit the same bug on other points in the codebase. Fix by changing all instances of "ebp" in a clobber list to use the push/pop %ebp workaround instead.

* [tcp] Reduce path MTU to 1280 bytesMichael Brown2013-09-041-3/+12
| | | | | | | | | | | | | | | | | | The path MTU is currently hardcoded to 1460 bytes, which fails to allow space for TCP options. Sending a maximum-sized datagram (which is viable when using HTTP POST) will therefore fail since the Ethernet MTU will be exceeded. Reduce the hardcoded path MTU to produce a maximum datagram of 1280 bytes, which is the size required of data link layers by IPv6. It is a reasonable assumption that all intermediary data link layers will be able to convey this packet without fragmentation, even for IPv4. Note that this reduction has a minimal impact upon download throughput, since it affects only the transmit data path.

* [ipv6] Fix uninitialised-variable warningMichael Brown2013-09-031-0/+3

* [ipv6] Replace IPv6 stackMichael Brown2013-09-0316-652/+1669
| | | | | | | | | | | | | | | | Replace the existing partially-implemented IPv6 stack with a fresh implementation. This implementation is not yet complete. The IPv6 transmit and receive datapaths are functional (including fragment reassembly and parsing of arbitrary extension headers). NDP neighbour solicitations and advertisements are supported. ICMPv6 echo is supported. At present, only link-local addresses may be used, and there is no way to specify an IPv6 address as part of a URI (either directly or via a DNS lookup).

* [neighbour] Generalise concept of neighbour discoveryMichael Brown2013-09-035-357/+579
| | | | | | | | Split the protocol-independent portions of arp.c into a separate file neighbour.c, to allow for sharing of functionality between IPv4+ARP and IPv6+NDP. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [tcpip] Pass through network device to transport layer protocolsMichael Brown2013-09-038-13/+26

* [netdevice] Add concept of a network device indexMichael Brown2013-09-032-2/+5
| | | | | | | | | | | | | IPv6 link-local socket addresses require some way to specify a local network device. We cannot simply use a pointer to the network device, since a struct sockaddr_in6 may be long-lived and has no way to hold a reference to the network device. Using a network device index allows a socket address to cleanly refer to a network device without worrying about whether or not that device continues to exist.

* [netdevice] Increase maximum network-layer address lengthMichael Brown2013-09-031-1/+1

* [3c90x] Fix High-MTU packet receptionThomas Miletich2013-08-201-0/+4

* [3c90x] Don't round up transmit packet lengthThomas Miletich2013-08-202-3/+5
| | | | | | | | | | The 3c90x B and C revisions support rounding up the packet length to a specific boundary. Disable this feature to avoid overlength packets. This fixes the loopback test. Signed-off-by: Thomas Miletich <thomas.miletich@gmail.com> Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [3c90x] Stall upload engine before setting RX ring addressThomas Miletich2013-08-201-0/+4

* [http] Add support for HTTP POSTMichael Brown2013-08-191-3/+121
| | | | | | | | | | | | | | Allow HTTP POST requests to be generated when the URI includes a parameter list. For example: #!ipxe params param mac ${net0/mac} param uuid ${uuid} param asset ${asset} chain http://boot.ipxe.org/demo/boot.php##params Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [uri] Allow URIs to incorporate a parameter listMichael Brown2013-08-192-1/+34
| | | | | | | | | | | | | | | | | HTTP POST requires the ability to associate a parameter list with a URI. There is no standardised syntax for this. Use a non-standard URI syntax to incorporate the specification of a parameter list within a URI: URI = [ absoluteURI | relativeURI ] [ "#" fragment ] [ "##params" [ "=" paramsName ] ] e.g. http://boot.ipxe.org/demo/boot.php##params http://boot.ipxe.org/demo/boot.php##params=mylist Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [settings] Expose memory map via settings mechanismMichael Brown2013-08-124-0/+247
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow memory map entries to be read using the syntax ${memmap/<region>.<properties>.<scale>} where <region> is the index of the memory region, <properties> is a bitmask where bit 0 represents the start address and bit 1 represents the length (allowing the end address to be encoded by having both bits 0 and 1 set), and <scale> is the number of bits by which to shift the result. This allows for several values of interest to be encoded. For example: ${memmap/<region>.1.0:hexraw} # 64-bit start address of <region> ${memmap/<region>.2.0:hexraw} # 64-bit length of <region>, in bytes ${memmap/<region>.3.0:hexraw} # 64-bit end address of <region> ${memmap/<region>.2.10:int32} # Length of <region>, in kB ${memmap/<region>.2.20:int32} # Length of <region>, in MB The numeric encoding is slightly more sophisticated than described here, allowing a single encoding to cover multiple regions. (See the source code for details.) The primary use case for this feature is to provide the total system memory size (in MB) via the "memsize" predefined setting.

* [settings] Allow numeric_setting_value() to handle long setting valuesMichael Brown2013-08-122-4/+10
| | | | | | | | | | | Allow numeric_setting_value() to handle e.g. the byte sequence 00:00:00:00:12:34:56:78 by returning -ERANGE only if the value actually overflows the return type. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [settings] Expose CPUID instruction via settings mechanismMichael Brown2013-08-076-19/+303
| | | | | | | | | | | | | | | | | | | | | | | Allow CPUID values to be read using the syntax ${cpuid/<register>.<function>} For example, ${cpuid/2.0x80000001} will give the value of %ecx after calling CPUID with %eax=0x80000001. Values for <register> are encoded as %eax=0, %ebx=1, %ecx=2, %edx=3. The numeric encoding is more sophisticated than described above, allowing for settings such as the CPU model (obtained by calling CPUID with %eax=0x80000002-0x80000004 inclusive and concatenating the values returned in %eax:%ebx:%ecx:%edx). See the source code for details. The "cpuvendor" and "cpumodel" settings provide easy access to these more complex CPUID settings. This functionality is intended to complement the "cpuid" command, which allows for testing individual CPUID feature bits. Signed-off-by: Michael Brown <mcb30@ipxe.org>
