[settings] Add the notion of a "tag magic" to numbered settings

2008-10-30T21:47:14+00:00

Settings can be constructed using a dotted-decimal notation, to allow for access to unnamed settings. The default interpretation is as a DHCP option number (with encapsulated options represented as ".". In several contexts (e.g. SMBIOS, Phantom CLP), it is useful to interpret the dotted-decimal notation as referring to non-DHCP options. In this case, it becomes necessary for these contexts to ignore standard DHCP options, otherwise we end up trying to, for example, retrieve the boot filename from SMBIOS. Allow settings blocks to specify a "tag magic". When dotted-decimal notation is used to construct a setting, the tag magic value of the originating settings block will be ORed in to the tag number. Store/fetch methods can then check for the magic number before interpreting arbitrarily-numbered settings.

[settings] Expose MAC address setting for general use

[autoboot] Retain initial-slash (if present) when constructing TFTP URIs

2008-07-31T15:55:46+00:00

When we boot from a DHCP-supplied filename, we previously relied on the fact that the current working URI is set to tftp://[next-server]/ in order to resolve the filename into a full tftp:// URI. However, this process will eliminate the distinction between filenames with and without initial slashes: cwuri="tftp://10.0.0.1/" filename="vmlinuz" => URI="tftp://10.0.0.1/vmlinuz" cwuri="tftp://10.0.0.1/" filename="/vmlinuz" => URI="tftp://10.0.0.1/vmlinuz" This distinction is important for some TFTP servers. We now explicitly construct a string of the form "tftp://[next-server]/filename" so that a filename with an initial slash will result in a URI containing a double-slash, e.g. "tftp://10.0.0.1//vmlinuz" The TFTP code always strips a single initial slash, and so ends up presenting the correct path to the server. URIs entered explicitly by users at the command line must include a double slash if they want an initial slash presented to the TFTP server: "kernel tftp://10.0.0.1/vmlinuz" => filename="vmlinuz" "kernel tftp://10.0.0.1//vmlinuz" => filename="/vmlinuz"

[Settings] Expose SMBIOS via settings API

2008-03-28T15:35:06+00:00

In particular, expose the system UUID as a setting ("smbios/uuid").

[Settings] Remove assumption that all settings have DHCP tag values

2008-03-25T20:46:16+00:00

Allow for settings to be described by something other than a DHCP option tag if desirable. Currently used only for the MAC address setting. Separate out fake DHCP packet creation code from dhcp.c to fakedhcp.c. Remove notion of settings from dhcppkt.c. Rationalise dhcp.c to use settings API only for final registration of the DHCP options, rather than using {store,fetch}_setting throughout.

[Settings] copy_settings() should not fail if some settings are missing!

2008-03-23T23:28:21+00:00

[Settings] Implement simple_settings backed with extensible DHCP options

2008-03-22T00:31:08+00:00

[Settings] Migrate DHCP and NVO code to the new settings API (untested)

2008-03-21T22:15:31+00:00

[Settings] Convert code in src/usr to use settings API.

2008-03-20T23:42:11+00:00

[Settings] Introduce settings applicators.

2008-03-20T23:15:48+00:00

Convert DHCP option applicators in dns.c and iscsi.c to settings applicators. Kill off DHCP option applicators.
