* [Settings] Expose SMBIOS via settings APIMichael Brown2008-03-282-3/+5
| | | | In particular, expose the system UUID as a setting ("smbios/uuid").
* [DHCP] Add support for ProxyDHCP requestsMichael Brown2008-03-271-3/+7
| | | | | | | | | | | | | | | | The PXE spec is (as usual) unclear on precisely when ProxyDHCPREQUESTs should be issued. We adapt the following, slightly paranoid approach: If an offer contains an IP address, then it is a normal DHCPOFFER. If an offer contains an option #60 "PXEClient", then it is a ProxyDHCPOFFER. Note that the same packet can be both a normal DHCPOFFER and a ProxyDHCPOFFER. After receiving the normal DHCPACK, if we have received a ProxyDHCPOFFER, we unicast a ProxyDHCPREQUEST back to the ProxyDHCP server on port 4011. If we time out waiting for a ProxyDHCPACK, we treat this as a non-fatal error.
* [Settings] Remove assumption that all settings have DHCP tag valuesMichael Brown2008-03-255-87/+122
| | | | | | | | | | | | 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!Michael Brown2008-03-241-2/+0Star

* [IPv4] Use default netmasks when no subnet mask is specified.Michael Brown2008-03-231-1/+7

* [IPv4] Tidy up some header files.Michael Brown2008-03-233-9/+23
|
* [DHCP] Fix up fake-packet creation as used by PXENV_GET_CACHED_INFOMichael Brown2008-03-231-7/+5Star
| | | | | | | | | | | Add dedicated functions create_dhcpdiscover(), create_dhcpack() and create_proxydhcpack() for use by external code such as the PXE preboot code. Register ProxyDHCP options under the global scope "proxydhcp". Unregister previously-acquired DHCP and ProxyDHCP settings when DHCP succeeds.
* [Settings] Implement simple_settings backed with extensible DHCP optionsMichael Brown2008-03-222-4/+30

* [Settings] Migrate DHCP and NVO code to the new settings API (untested)Michael Brown2008-03-216-115/+102Star

* [DHCP] Kill off some no-longer-used DHCP functionsMichael Brown2008-03-211-10/+0Star

* [Settings] Use a settings applicator to set the default TFTP URI.Michael Brown2008-03-211-3/+0Star
|
* [Settings] Use a settings applicator to configure IPv4 routes.Michael Brown2008-03-213-8/+11
|
* [Settings] Convert code in src/usr to use settings API.Michael Brown2008-03-211-0/+3
|
* [Settings] Introduce settings applicators.Michael Brown2008-03-212-31/+18Star
| | | | | | | Convert DHCP option applicators in dns.c and iscsi.c to settings applicators. Kill off DHCP option applicators.
* [Settings] Add per-netdevice settings blockMichael Brown2008-03-204-1/+17
| | | | | | | | | Add a configuration settings block for each net device. This will provide the parent scope for settings applicable only to that network device (e.g. non-volatile options stored on the NIC, options obtained via DHCP, etc.). Expose the MAC address as a setting.
* [Settings] Add settings hierarchyMichael Brown2008-03-201-46/+85
| | | | | | | | Add the notion of the settings hierarchy, complete with register/unregister routines. Rename set->store and get->fetch to avoid naming conflicts with get/put as used in reference counting.
* [Settings] Start revamping the configuration settings API.Michael Brown2008-03-202-82/+124
| | | | | | | | | | | | | | | | Add the concept of an abstract configuration setting, comprising a (DHCP) tag value and an associated byte sequence. Add the concept of a settings namespace. Add functions for extracting string, IPv4 address, and signed and unsigned integer values from configuration settings (analogous to dhcp_snprintf(), dhcp_ipv4_option(), etc.). Update functions for parsing and formatting named/typed options to work with new settings API. Update NVO commands and config UI to use new settings API.
* [Timers] Initialise timers on first useMichael Brown2008-03-181-0/+1
| | | | | | | Timers are sometimes required before the call to initialise(), so we cannot rely on initialise() to set up the timers before use. Also fix a potential integer overflow issue in generic_currticks_udelay()
* [Timers] Miscellaneous timer system fixesMichael Brown2008-03-182-21/+22
| | | | | | | | | Add missing comments to timer code. Lock system if no suitable timer source is found. Fix initialisation order so that timers are initialised before code that needs to use them.
* [Settings] show_setting() functions return snprintf()-style length.Michael Brown2008-03-181-2/+2
| | | | | | show_setting() and related functions now return an "actual length" in the style of snprintf(). This is to allow consumers to allocate buffers large enough to hold the formatted setting.
* Modify gPXE core and drivers to work with the new timer subsystemAlexey Zaytsev2008-03-022-2/+0Star

* Introduce the new timer subsystem.Alexey Zaytsev2008-03-021-0/+32
| | | | | | | | | | | | | | | | | | | | | | | | | Timer subsystem initialization code in core/timer.c Split the BIOS and RTDSC timer drivers from i386_timer.c Split arch/i386/firmware/pcbios/bios.c into the RTSDC timer driver and arch/i386/core/nap.c Split the headers properly: include/unistd.h - delay functions to be used by the gPXE core and drivers. include/gpxe/timer.h - the fimer subsystem interface to be used by the timer drivers and currticks() to be used by the code gPXE subsystems. include/latch.h - removed include/timer.h - scheduled for removal. Some driver are using currticks, which is only for core subsystems. Signed-off-by: Alexey Zaytsev <alexey.zaytsev@gmail.com>
* [Infiniband] Add preliminary support for multi-port devices.Michael Brown2008-02-271-14/+124
| | | | | | | | | | Arbel and Hermon cards both have multiple ports. Add the infrastructure required to register each port as a separate IB device. Don't yet register more than one port, since registration will currently fail unless a valid link is detected. Use ib_*_{set,get}_{drv,owner}data wrappers to access driver- and owner-private data on Infiniband structures.
* [Infiniband] Centralise MAD operationsMichael Brown2008-02-261-7/+70
