* [dhcp] Copy exactly the required length when resizing DHCP optionsMichael Brown2014-02-261-3/+1Star
| | | | | | | | | | | When resizing DHCP options, iPXE currently calculates the length to be copied by subtracting the destination pointer from the end of buffer pointer. This works and guarantees not to write beyond the end of the buffer, but may end up reading beyond the end of the buffer. Fix by calculating the required length exactly.

* [settings] Formalise notion of setting applicabilityMichael Brown2011-03-221-0/+12
| | | | | | | | | | | | | | | 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".

* [dhcp] Allow use of custom reallocation functions for DHCP option blocksMichael Brown2011-01-111-56/+59
| | | | | | | | 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>
* [dhcp] Rename length fields for DHCP optionsMichael Brown2011-01-101-17/+17
| | | | | | Rename "len" to "used_len" and "max_len" to "alloc_len". Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [build] Rename gPXE to iPXEMichael Brown2010-04-201-2/+2
| | | | | | | | | | | Access to the gpxe.org and etherboot.org domains and associated resources has been revoked by the registrant of the domain.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.

* [dhcp] Append new DHCP options versus prependShao Miller2010-01-141-4/+15
| | | | | | | | | | | | | Change the behaviour for adding DHCP options into a DHCP packet so that we now append options, rather than insert them in front of whatever options might already be present. Apparently, the DHCP relay logic on a Nortel 470-48T layer 2 switch cares about the order of DHCP options. If we build a DHCP packet pre-populated with some options, their order will now be preserved, except for encapsulated options. Signed-off-by: Marty Connor <mdc@etherboot.org>
* [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] Remove assumption that all settings have DHCP tag valuesMichael Brown2008-03-251-3/+13
| | | | | | | | | | | | 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.

* Allow for calling find_dhcp_option() with "options" set to NULL, in orderMichael Brown2006-07-191-21/+97
| | | | | | | to search through all registered option blocks. Move some static inlines that are likely to be used frequently into dhcpopts.c as normal functions, to save space.
* Add sketch code to reassemble a DHCP packet from our internal "everythingMichael Brown2006-07-171-8/+24
| | | | | | | | | | is a DHCP option" data structures. We need this code in order to be able to return a DHCP packet to a PXE NBP which reflects options from our multiple sources (e.g. NVS and DHCP server). This is expensive, but necessary. Having paid this cost, we may as well try to use the same code to generate our DHCP request packets, since the process is similar.
