[block] Describe all SAN devices via ACPI tables

2017-03-28T16:12:48+00:00

Describe all SAN devices via ACPI tables such as the iBFT. For tables that can describe only a single device (i.e. the aBFT and sBFT), one table is installed per device. For multi-device tables (i.e. the iBFT), all devices are described in a single table. An underlying SAN device connection may be closed at the time that we need to construct an ACPI table. We therefore introduce the concept of an "ACPI descriptor" which enables the SAN boot code to maintain an opaque pointer to the underlying object, and an "ACPI model" which can build tables from a list of such descriptors. This separates the lifecycles of ACPI descriptions from the lifecycles of the block device interfaces, and allows for construction of the ACPI tables even if the block device interface has been closed. For a multipath SAN device, iPXE will wait until sufficient information is available to describe all devices but will not wait for all paths to connect successfully. For example: with a multipath iSCSI boot iPXE will wait until at least one path has become available and name resolution has completed on all other paths. We do this since the iBFT has to include IP addresses rather than DNS names. We will commence booting without waiting for the inactive paths to either become available or close; this avoids unnecessary boot delays. Note that the Linux kernel will refuse to accept an iBFT with more than two NIC or target structures. We therefore describe only the NICs that are actually required in order to reach the described targets. Any iBFT with at most two targets is therefore guaranteed to describe at most two NICs.

[infiniband] Return status code from ib_create_cq() and ib_create_qp()

2017-03-22T09:18:02+00:00

Any underlying errors arising during ib_create_cq() or ib_create_qp() are lost since the functions simply return NULL on error. This makes debugging harder, since a debug-enabled build is required to discover the root cause of the error. Fix by returning a status code from these functions, thereby allowing any underlying errors to be propagated. Signed-off-by: Michael Brown

[netdevice] Limit MTU by hardware maximum frame length

2017-01-25T14:55:09+00:00

Separate out the concept of "hardware maximum supported frame length" and "configured link MTU", and limit the latter according to the former. In networks where the DHCP-supplied link MTU is inconsistent with the hardware or driver capabilities (e.g. a network using jumbo frames), this will result in iPXE advertising a TCP MSS consistent with a size that can actually be received. Note that the term "MTU" is typically used to refer to the maximum length excluding the link-layer headers; we adopt this usage. Signed-off-by: Michael Brown
