[dhcp] Fall back to using the hardware address to populate the chaddr field

2009-08-11T23:27:08+00:00

For IPoIB, the chaddr field is too small (16 bytes) to contain the 20-byte IPoIB link-layer address. RFC4390 mandates that we should pass an empty chaddr field and rely on the DHCP client identifier instead. This has many problems, not least of which is that a client identifier containing an IPoIB link-layer address is not very useful from the point of view of creating DHCP reservations, since the QPN component is assigned at runtime and may vary between boots. Leave the DHCP client identifier as-is, to avoid breaking existing setups as far as possible, but expose the real hardware address (the port GUID) via the DHCP chaddr field, using the broadcast flag to instruct the DHCP server not to use this chaddr value as a link-layer address. This makes it possible (at least with ISC dhcpd) to create DHCP reservations using host declarations such as: host duckling { fixed-address 10.252.252.99; hardware unknown-32 00:02:c9:02:00:25:a1:b5; }

[netdevice] Separate out the concept of hardware and link-layer addresses

2009-08-11T23:19:14+00:00

The hardware address is an intrinsic property of the hardware, while the link-layer address can be changed at runtime. This separation is exposed via APIs such as PXE and EFI, but is currently elided by gPXE. Expose the hardware and link-layer addresses as separate properties within a net device. Drivers should now fill in hw_addr, which will be used to initialise ll_addr at the time of calling register_netdev().

[ifmgmt] Move link-up status messages from autoboot() to iflinkwait()

2009-06-24T12:15:27+00:00

With the addition of link status codes, we can now display a detailed error indication if iflinkwait() fails. Putting the error output in iflinkwait avoids code duplication, and gains symmetry with the other interface management routines; ifopen() already prints an error directly if it cannot open its interface.

[netdevice] Add mechanism for reporting detailed link status codes

2009-06-24T12:04:36+00:00

Expand the NETDEV_LINK_UP bit into a link_rc status code field, allowing specific reasons for link failure to be reported via "ifstat". Originally-authored-by: Joshua Oreman

[legal] Add a selection of FILE_LICENCE declarations

2009-05-18T07:33:25+00:00

Add FILE_LICENCE declarations to almost all files that make up the various standard builds of gPXE.

[tables] Redefine methods for accessing linker tables

2009-03-13T02:06:30+00:00

Intel's C compiler (icc) chokes on the zero-length arrays that we currently use as part of the mechanism for accessing linker table entries. Abstract away the zero-length arrays, to make a port to icc easier. Introduce macros such as for_each_table_entry() to simplify the common case of iterating over all entries in a linker table. Represent table names as #defined string constants rather than unquoted literals; this avoids visual confusion between table names and C variable or type names, and also allows us to force a compilation error in the event of incorrect table names.

[pxe] Allow Escape to abort PXE menu selections

2009-02-17T07:35:57+00:00

Other vendor PXE stacks tend to allow the Escape key to be used to abort menu selection. Allow Escape (as well as Ctrl-C) to abort selection.

[image] Allow multiple embedded images

2009-02-16T00:30:36+00:00

This patch extends the embedded image feature to allow multiple embedded images instead of just one. gPXE now always boots the first embedded image on startup instead of doing the hardcoded DHCP boot (aka autoboot). Based heavily upon a patch by Stefan Hajnoczi .
