* [libc] Fix isdigit(), islower() and isupper().Michael Brown2008-05-191-4/+3Star
| | | | From: Stefan Hajnoczi <stefanha@gmail.com>
* [MTNIC] Minor cleanups of vendor-provided driver for Mellanox 10GigE cardsMichael Brown2008-04-221-0/+1
| | | | | | | | | Drivers are not allowed to call printf(). Converted eprintf() to DBG(), and removed spurious startup banner. Fixed hardcoded inclusion of little_bswap.h Use EIO rather than 1 as an error number.
* [NETDEV] Add notion of link stateMichael Brown2008-04-223-0/+36
| | | | | | | | | | | Add ability for network devices to flag link up/down state to the networking core. Autobooting code will now wait for link-up before attempting DHCP. IPoIB reflects the Infiniband link state as the network device link state (which is not strictly correct; we also need a succesful IPoIB IPv4 broadcast group join), but is probably more informative.
* [Infiniband] Move event-queue process from driver to Infiniband coreMichael Brown2008-04-211-1/+33
|
* [Infiniband] Add preliminary multiple port support for Hermon cardsMichael Brown2008-04-182-0/+21
| | | | | | | | | | | | Infiniband devices no longer block waiting for link-up in register_ibdev(). Hermon driver needs to create an event queue and poll for link-up events. Infiniband core needs to reread MAD parameters when link state changes. IPoIB needs to cope with Infiniband link parameters being only partially available at probe and open time.
* [Drivers-r8169] Add support for newer rtl8169 variants from Hilko BengenMarty Connor2008-03-311-0/+3
| | | | | 03-19-2008, Hilko Bengen, Cleanups and fixes for newer cards (successfully tested with 8110SC-d onboard NIC)
* [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.
* [libc] Whitespace cleanup in errno.hMichael Brown2008-03-261-1/+1

* [PXEXT] Change the PXE return code for EWOULDBLOCKH. Peter Anvin2008-03-261-2/+2
| | | | | | | | | | | Change the PXE return code for EWOULDBLOCK from PXENV_STATUS_FAILURE to PXENV_STATUS_TFTP_OPEN. This code is only used by the FILE_READ PXEXT call, and is necessary to distinguish "error" from "no data" in that call. (The only other nonblocking call is UDP_READ, where the caller doesn't care about the distinction, however, gPXE doesn't use EWOULDBLOCK internally to represent this condition in that code.)
* [PXEXT] Add FILE_API_CHECK API functionH. Peter Anvin2008-03-262-0/+27
| | | | | Add FILE_API_CHECK to the PXEXT API so the NBP can query the availability and status of the API.
* [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.
* [libc] Use __builtin_va_list et al in stdarg.hMichael Brown2008-03-241-0/+10
| | | | | The home-grown versions don't work properly for static variadic functions, when gcc can choose to use a non-standard calling convention.
* [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 Brown2008-03-235-61/+23Star
|
* [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] 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* | [PXEXT] Add PXENV_FILE_EXEC call to PXE extensions API.Michael Brown2008-03-042-0/+23
| | | | | | | | | | | | | | | | This allows pxelinux to execute arbitrary gPXE commands. This is remarkably unsafe (not least because some of the commands will assume full ownership of memory and do nasty things like edit the e820 map underneath the calling pxelinux), but it does allow access to the "sanboot" command.

* [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
