* [ipv6] Allow for multiple routersMichael Brown2016-07-252-2/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Select the IPv6 source address and corresponding router (if any) using a very simplified version of the algorithm from RFC6724: - Ignore any source address that has a smaller scope than the destination address. For example, do not use a link-local source address when sending to a global destination address. - If we have a source address which is on the same link as the destination address, then use that source address. - If we are left with multiple possible source addresses, then choose the address with the smallest scope. For example, if we are sending to a site-local destination address and we have both a global source address and a site-local source address, then use the site-local source address. - If we are still left with multiple possible source addresses, then choose the address with the longest matching prefix. For the purposes of this algorithm, we treat RFC4193 Unique Local Addresses as having organisation-local scope. Since we use only link-local scope for our multicast transmissions, this approximation should remain valid in all practical situations.

* [ipv6] Create routing table based on IPv6 settingsMichael Brown2016-07-201-4/+6
| | | | | | | | | | | | | | | | | | | | | | Use the IPv6 settings to construct the routing table, in a matter analogous to the construction of the IPv4 routing table. This allows for manual assignment of IPv6 addresses via e.g. set net0/ip6 2001:ba8:0:1d4::6950:5845 set net0/len6 64 set net0/gateway6 fe80::226:bff:fedd:d3c0 The prefix length ("len6") may be omitted, in which case a default prefix length of 64 will be assumed. Multiple IPv6 addresses may be assigned manually by implicitly creating child settings blocks. For example: set net0/ip6 2001:ba8:0:1d4::6950:5845 set net0.ula/ip6 fda4:2496:e992::6950:5845 Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [ipv6] Match user expectations for IPv6 settings prioritiesMichael Brown2016-07-191-0/+12
| | | | | | | | | | | | | | A reasonable user expectation is that ${net0/ip6} should show the "highest-priority" of the IPv6 addresses, even when multiple IPv6 addresses are active. The expected order of priority is likely to be manually-assigned addresses first, then stateful DHCPv6 addresses, then SLAAC addresses, and lastly link-local addresses. Using ${priority} to enforce an ordering is undesirable since that would affect the priority assigned to each of the net<N> blocks as a whole, so use the sibling ordering capability instead.

* [efi] Install the HII config access protocol on a child of the SNP handleLaszlo Ersek2016-07-081-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In edk2, there are several drivers that associate HII forms (and corresponding config access protocol instances) with each individual network device. (In this context, "network device" means the EFI handle on which the SNP protocol is installed, and on which the device path ending with the MAC() node is installed also.) Such edk2 drivers are, for example: Ip4Dxe, HttpBootDxe, VlanConfigDxe. In UEFI, any given handle can carry at most one instance of a specific protocol (see e.g. the specification of the InstallProtocolInterface() boot service). This implies that the class of drivers mentioned above can't install their EFI_HII_CONFIG_ACCESS_PROTOCOL instances on the SNP handle directly -- they would conflict with each other. Accordingly, each of those edk2 drivers creates a "private" child handle under the SNP handle, and installs its config access protocol (and corresponding HII package list) on its child handle. The device path for the child handle is traditionally derived by appending a Hardware Vendor Device Path node after the MAC() node. The VenHw() nodes in question consist of a GUID (by definition), and no trailing data (by choice). The purpose of these VenHw() nodes is only that all the child nodes can be uniquely identified by device path. At the moment iPXE does not follow this pattern. It doesn't run into a conflict when it installs its EFI_HII_CONFIG_ACCESS_PROTOCOL directly on the SNP handle, but that's only because iPXE is the sole driver not following the pattern. This behavior seems risky (one might call it a "latent bug"); better align iPXE with the edk2 custom.

* [profile] Allow profiling to be globally enabled or disabledMichael Brown2016-07-051-0/+2

* [libc] Allow assertions to be globally enabled or disabledMichael Brown2016-07-051-0/+2
| | | | | | | | | | | | | | | | | | | | | | | Assertions are enabled for objects built with any debug level (including an explicit debug level of zero). It is sometimes useful to be able to enable assertions across all objects; this currently requires manually hacking include/assert.h. Allow assertions to be globally enabled by adding ASSERT=1 to the build command line. For example: make bin/8086100e.mrom ASSERT=1 Similarly, allow assertions to be globally disabled by adding ASSERT=0 to the build command line. If no ASSERT=... is specified on the build command line, then only objects mentioned in DEBUG=... will have assertions enabled (as is currently the case). Note than globally enabling assertions imposes a relatively heavy runtime penalty, primarily due to the various sanity checks performed by list_add(), list_for_each_entry(), etc. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [debug] Allow debug messages to be initially disabled at runtimeMichael Brown2016-07-051-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extend the DEBUG=... syntax to allow debug messages to be compiled in but disabled by default. For example: make bin/undionly.kpxe DEBUG=netdevice:3:1 would compile in the messages as for DEBUG=netdevice:3, but would set the debug level mask so that only the DEBUG=netdevice:1 messages would be displayed. This allows for external code to selectively enable the additional debug messages at runtime, without being overwhelmed by unwanted initial noise. For example, a developer of a new protocol may want to temporarily enable tracing of all packets received: this can be done by building with DEBUG=netdevice:3:1 and using // temporarily enable per-packet messages DBG_ENABLE_OBJECT ( netdevice, DBGLVL_EXTRA ); ... // disable per-packet messages DBG_DISABLE_OBJECT ( netdevice, DBGLVL_EXTRA ); Note that unlike the usual DBG_ENABLE() and DBG_DISABLE() macros, DBG_ENABLE_OBJECT() and DBG_DISABLE_OBJECT() will not be removed via dead code elimination if debugging is disabled in the specified object. In particular, this means that using either of these macros will always result in a symbol reference to the specified object. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [debug] Allow per-object runtime enabling/disabling of debug messagesMichael Brown2016-07-051-4/+13
| | | | | | | | | | | | | | | | | | | | | | | | | The DBG_ENABLE() and DBG_DISABLE() macros currently affect the debug level of all objects that were built with debugging enabled. This is undesirable, since it is common to use different debug levels in each object. Make the debug level mask a per-object variable. DBG_ENABLE() and DBG_DISABLE() now control only the debug level for the containing object (which is consistent with the intended usage across the existing codebase). DBG_ENABLE_OBJECT() and DBG_DISABLE_OBJECT() may be used to control the debug level for a specified object. For example: // Enable DBG() messages from tcpip.c DBG_ENABLE_OBJECT ( tcpip, DBGLVL_LOG ); Note that the existence of debug messages continues to be gated by the DEBUG=... list specified on the build command line. If an object was built without the relevant debug level, then DBG_ENABLE_OBJECT() will have no effect on that object at runtime (other than to explicitly drag in the object via a symbol reference).

* [dhcp] Automatically generate vendor class identifier stringMichael Brown2016-07-041-0/+23

* [dhcpv6] Include vendor class identifier option in DHCPv6 requestsMichael Brown2016-07-041-11/+32
| | | | | | | | | | | | | | | | | | | | | | | | RFC3315 defines DHCPv6 option 16 (vendor class identifier) but does not define any direct relationship with the roughly equivalent DHCPv4 option 60. The PXE specification predates IPv6, and the UEFI specification is expectedly vague on the subject. Examination of the reference EDK2 codebase suggests that the DHCPv6 vendor class identifier will be formatted in accordance with RFC3315, using a single vendor-class-data item in which the opaque-data field is the string as would appear in DHCPv4 option 60. RFC3315 requires the vendor class identifier to specify an IANA enterprise number, as a way of disambiguating the vendor-class-data namespace. The EDK2 code uses the value 343, described as: // TODO: IANA TBD: temporarily using Intel's Since this "TODO" has been present since at least 2010, it is probably safe to assume that it has now become a de facto standard.

* [tcp] Send TCP keepalives on idle established connectionsMichael Brown2016-06-131-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | In some circumstances, intermediate devices may lose state in a way that temporarily prevents the successful delivery of packets from a TCP peer. For example, a firewall may drop a NAT forwarding table entry. Since iPXE spends most of its time downloading files (and hence purely receiving data, sending only TCP ACKs), this can easily happen in a situation in which there is no reason for iPXE's TCP stack to generate any retransmissions. The temporary loss of connectivity can therefore effectively become permanent. Work around this problem by sending TCP keepalives after a period of inactivity on an established connection. TCP keepalives usually send a single garbage byte in sequence number space that has already been ACKed by the peer. Since we do not need to elicit a response from the peer, we instead send pure ACKs (with no garbage data) in order to keep the transmit code path simple.

RFC4578 section 2.1 defines type 7 as "EFI BC" and type 9 as "EFI x86-64"; the IANA registry quotes RFC4578 as its source but has these values erroneously swapped.
