* [legal] Relicense files under GPL2_OR_LATER_OR_UBDLMichael Brown2015-03-021-1/+5
| | | | | | | Relicense files for which I am the sole author (as identified by util/relicense.pl). Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [settings] Explicitly separate the concept of a completed fetched settingMichael Brown2013-12-051-2/+2
| | | | | | | | | | The fetch_setting() family of functions may currently modify the definition of the specified setting (e.g. to add missing type information). Clean up this interface by requiring callers to provide an explicit buffer to contain the completed definition of the fetched setting, if required. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [settings] Eliminate settings "tag magic"Michael Brown2013-05-011-2/+4
| | | | | | | Create an explicit concept of "settings scope" and eliminate the magic values used for numerical setting tags. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [settings] Formalise notion of setting applicabilityMichael Brown2011-03-221-0/+14
| | | | | | | | | | | | | | | Expose a function setting_applies() to allow a caller to determine whether or not a particular setting is applicable to a particular settings block. Restrict DHCP-backed settings blocks to accepting only DHCP-based settings. Restrict network device settings blocks to accepting only DHCP-based settings and network device-specific settings such as "mac".

* [nvo] Allow resizing of non-volatile stored option blocksMichael Brown2011-01-191-49/+103

* [nvo] Remove the non-volatile options fragment listMichael Brown2011-01-111-49/+24Star
| | | | | | | | | Since its implementation several years ago, no driver has used a fragment list containing more than a single fragment. Simplify the NVO core and the drivers that use it by removing the whole concept of the fragment list, and using a simple (address,length) pair instead. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [dhcp] Allow use of custom reallocation functions for DHCP option blocksMichael Brown2011-01-111-1/+2
| | | | | | | | Allow functions other than realloc() to be used to reallocate DHCP option block data, and specify the reallocation function at the time of calling dhcpopt_init(). Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [settings] Apply settings block name in register_settings()Michael Brown2010-12-011-3/+2Star
| | | | | | | | Pass the settings block name as a parameter to register_settings(), rather than defining it with settings_init() (and then possibly changing it by directly manipulating settings->name). Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [nvo] Allow fragment list to be omittedMichael Brown2010-11-251-6/+20
| | | | | | | | Allow the fragment list to be omitted when calling nvo_init(). Omitting the list will cause the whole of the NVS device to be used for NVO storage. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [build] Rename gPXE to iPXEMichael Brown2010-04-201-3/+3
| | | | | | | | | | | Access to the gpxe.org and etherboot.org domains and associated resources has been revoked by the registrant of the domain. Work around this problem by renaming project from gPXE to iPXE, and updating URLs to match. Also update README, LOG and COPYRIGHTS to remove obsolete information.

* [legal] Add a selection of FILE_LICENCE declarationsMichael Brown2009-05-181-0/+2
| | | | | Add FILE_LICENCE declarations to almost all files that make up the various standard builds of gPXE.
* [settings] Add the notion of a "tag magic" to numbered settingsMichael Brown2008-10-301-1/+1
| | | | | | | | | | | | | | | | | | | 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 "<encapsulating option>.<encapsulated option>". 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] Remove assumption that all settings have DHCP tag valuesMichael Brown2008-03-251-6/+7
| | | | | | | | | | | | 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.
