* [linux] Add empty smbiosPiotr Jaroszyński2010-08-191-0/+37
| | | | | | | | | There exists an smbios userspace library so implementing this is probably possible, but doesn't seem really important to have in userspace. Hence provide a dummy implementation returning an error. Signed-off-by: Piotr Jaroszyński <p.jaroszynski@gmail.com> Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [linux] Add uaccessPiotr Jaroszyński2010-08-191-0/+38
| | | | | | | | | | | | | | | Add user access API for linux. On linux userspace virtual == user == phys addresses. Physical addresses also being the same is wrong, but there is no general way of converting userspace addresses to physical as what appears to be contiguous in userspace is physically fragmented. Currently only the DMA memory is special-cased, but its conversion to bus addresses is done in phys_to_bus. This is known to break virtio as it is passing phys addresses to the virtual device.

* [ioapi] Move get_memmap() to the I/O API groupPiotr Jaroszyński2010-08-161-0/+12
| | | | | | | | | pcbios specific get_memmap() is used by the b44 driver making all-drivers builds fail on other platforms. Move it to the I/O API group and provide a dummy implementation on EFI.

* [efi] Add the "snpnet" driverGeoff Lywood2010-06-021-1/+22
| | | | | | | | | Add a new network driver that consumes the EFI Simple Network Protocol. Also add a bus driver that can find the Simple Network Protocol that iPXE was loaded from; the resulting behavior is similar to the "undionly" driver for BIOS systems.

* [build] Rename gPXE to iPXEMichael Brown2010-04-2012-50/+50
| | | | | | | | | | | Access to the gpxe.org and etherboot.org domains and associated resources has been revoked by the registrant of the domain.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.

* [netdevice] Add netdev_is_open() wrapper functionMichael Brown2010-03-231-2/+2
| | | | Signed-off-by: Michael Brown <mcb30@etherboot.org>
* [netdevice] Allow the hardware and link-layer addresses to differ in sizeMichael Brown2009-08-121-4/+5
| | | | | | | | | | IPoIB has a 20-byte link-layer address, of which only eight bytes represent anything relating to a "hardware address". The PXE and EFI SNP APIs expect the permanent address to be the same size as the link-layer address, so fill in the "permanent address" field with the initial link layer address (as generated by register_netdev() based upon the real hardware address).
* [netdevice] Separate out the concept of hardware and link-layer addressesMichael Brown2009-08-121-1/+1
| | | | | | | | | | | The hardware address is an intrinsic property of the hardware, while the link-layer address can be changed at runtime. This separation is exposed via APIs such as PXE and EFI, but is currently elided by gPXE. Expose the hardware and link-layer addresses as separate properties within a net device. Drivers should now fill in hw_addr, which will be used to initialise ll_addr at the time of calling register_netdev().
* [netdevice] Make ll_broadcast per-netdevice rather than per-ll_protocolMichael Brown2009-07-181-2/+1Star
| | | | | | | | | IPoIB has a link-layer broadcast address that varies according to the partition key. We currently go through several contortions to pretend that the link-layer address is a fixed constant; by making the broadcast address a property of the network device rather than the link-layer protocol it will be possible to simplify IPoIB's broadcast handling.
* [netdevice] Add netdev argument to link-layer push and pull handlersJoshua Oreman2009-06-231-3/+4
| | | | | | | | | | | | | | | In order to construct outgoing link-layer frames or parse incoming ones properly, some protocols (such as 802.11) need more state than is available in the existing variables passed to the link-layer protocol handlers. To remedy this, add struct net_device *netdev as the first argument to each of these functions, so that more information can be fetched from the link layer-private part of the network device. Updated all three call sites (netdevice.c, efi_snp.c, pxe_undi.c) and both implementations (ethernet.c, ipoib.c) of ll_protocol to use the new argument.

* [settings] Allow for arbitrarily-named settingsMichael Brown2009-05-261-17/+0Star
| | | | | This provides a mechanism for using arbitrarily-named variables within gPXE, using the existing syntax for settings.
* [legal] Add a selection of FILE_LICENCE declarationsMichael Brown2009-05-1812-0/+24
| | | | | Add FILE_LICENCE declarations to almost all files that make up the various standard builds of gPXE.
* [smbios] Add asset tag settingTimothy Stack2009-04-151-0/+8
| | | | | | Add SMBIOS asset tag as a named setting. Signed-off-by: Michael Brown <mcb30@etherboot.org>
* [tables] Redefine methods for accessing linker tablesMichael Brown2009-03-131-14/+2Star
| | | | | | | | | | | | | | | Intel's C compiler (icc) chokes on the zero-length arrays that we currently use as part of the mechanism for accessing linker table entries. Abstract away the zero-length arrays, to make a port to icc easier. Introduce macros such as for_each_table_entry() to simplify the common case of iterating over all entries in a linker table. Represent table names as #defined string constants rather than unquoted literals; this avoids visual confusion between table names and C variable or type names, and also allows us to force a compilation error in the event of incorrect table names.
* [iobuf] Add iob_disown() and use it where it simplifies codeMichael Brown2009-02-011-2/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | There are many functions that take ownership of the I/O buffer they are passed as a parameter. The caller should not retain a pointer to the I/O buffer. Use iob_disown() to automatically nullify the caller's pointer, e.g.: xfer_deliver_iob ( xfer, iob_disown ( iobuf ) ); This will ensure that iobuf is set to NULL for any code after the call to xfer_deliver_iob(). iob_disown() is currently used only in places where it simplifies the code, by avoiding an extra line explicitly setting the I/O buffer pointer to NULL. It should ideally be used with each call to any function that takes ownership of an I/O buffer. (The SSA optimisations will ensure that use of iob_disown() gets optimised away in cases where the caller makes no further use of the I/O buffer pointer anyway.) If gcc ever introduces an __attribute__((free)), indicating that use of a function argument after a function call should generate a warning, then we should use this to identify all applicable function call sites, and add iob_disown() as necessary.
* [efi] Expose both GUIDs for the EFI_NETWORK_INTERFACE_IDENTIFIER_PROTOCOLMichael Brown2009-01-121-7/+12
| | | | | | | At some point, it seems that someone decided to change the GUID for the EFI_NETWORK_INTERFACE_IDENTIFIER_PROTOCOL. Current EFI builds ignore the older GUID, older EFI builds ignore the newer GUID, so we have to expose both.
* [efi] Add an EFI_NETWORK_INTERFACE_IDENTIFIER_PROTOCOL interfaceMichael Brown2009-01-121-0/+24
| | | | | This allegedly optional interface seems to be compulsory if you want EFI's PXE code to bother trying to use your network interface.
* [efi] Provide component name protocol and device path protocol interfacesMichael Brown2009-01-121-22/+151
| | | | | | | | | | | | | | Include a minimal component name protocol so that the driver name shows up as something other than "<UNKNOWN>" in the driver list, and a device path protocol so that the network interface shows up as a separate device in the device list, rather than being attached directly to the PCI device. Incidentally, the EFI component name protocol reaches new depths for signal-to-noise ratio in program code. A typical instance within the EFI development kit will use an additional 300 lines of code to provide slightly less functionality than GNU gettext achieves with three additional characters.
* [efi] Use elf2efi utility in place of efilinkMichael Brown2009-01-071-6/+4Star
| | | | | | | | | | | elf2efi converts a suitable ELF executable (containing relocation information, and with appropriate virtual addresses) into an EFI executable. It is less tightly coupled with the gPXE build process and, in particular, does not require the use of a hand-crafted PE image header in efiprefix.S. elf2efi correctly handles .bss sections, which significantly reduces the size of the gPXE EFI executable.
* [efi] Use EFI-native mechanism for accessing SMBIOS tableMichael Brown2008-12-053-0/+441
| | | | | | EFI provides a copy of the SMBIOS table accessible via the EFI system table, which we should use instead of manually scanning through the F000:0000 segment.
* [efi] Allow use of EFI configuration tablesMichael Brown2008-12-051-4/+45
| | | | | | | EFI passes in copies of SMBIOS and other system configuration tables via the EFI system table. Allow configuration tables to be requested using a mechanism similar to the current method for requesting EFI protocols.
* [x86_64] Fix assorted 64-bit compilation errors and warningsMichael Brown2008-11-191-18/+25
| | | | | | Remove various 32-bit assumptions scattered throughout the codebase. The code is still not necessarily 64-bit clean, but will at least compile.
* [efi] Add efi_strerror()Michael Brown2008-11-197-25/+73
| | | | | | | | | EFI_STATUS is defined as an INTN, which maps to UINT32 (i.e. unsigned int) on i386 and UINT64 (i.e. unsigned long) on x86_64. This would require a cast each time the error status is printed. Add efi_strerror() to avoid this ickiness and simultaneously enable prettier reporting of EFI status codes.
* [i386] Change [u]int32_t to [unsigned] int, rather than [unsigned] longMichael Brown2008-11-196-27/+27
| | | | | | This brings us in to line with Linux definitions, and also simplifies adding x86_64 support since both platforms have 2-byte shorts, 4-byte ints and 8-byte long longs.
* [pxe] Move all PXE files to arch/i386Michael Brown2008-11-187-2441/+0Star
| | | | | The initial PXE implementation in Etherboot had the goal of being architecture-agnostic, but this goal has not been realised.
* [netdevice] Retain and report detailed error breakdownsMichael Brown2008-11-082-15/+18
| | | | | | | | | | netdev_rx_err() and netdev_tx_complete_err() get passed the error code, but currently use it only in debug messages. Retain error numbers and frequencey counts for up to NETDEV_MAX_UNIQUE_ERRORS (4) different errors for each of TX and RX. This allows the "ifstat" command to report the reasons for TX/RX errors in most cases, even in non-debug builds.
* [efi] Add basic implementation of EFI SIMPLE_NETWORK_PROTOCOLMichael Brown2008-10-161-0/+978
| | | | | This implementation is tested and working, but not currently tied in to the EFI build.
* [netdevice] Change link-layer push() and pull() methods to take raw typesMichael Brown2008-10-161-9/+10
| | | | | | | | | | EFI requires us to be able to specify the source address for individual transmitted packets, and to be able to extract the destination address on received packets. Take advantage of this to rationalise the push() and pull() methods so that push() takes a (dest,source,proto) tuple and pull() returns a (dest,source,proto) tuple.
* [efi] Add EFI image format and basic runtime environmentMichael Brown2008-10-137-0/+886
| | | | | | | | | We have EFI APIs for CPU I/O, PCI I/O, timers, console I/O, user access and user memory allocation. EFI executables are created using the vanilla GNU toolchain, with the EXE header handcrafted in assembly and relocations generated by a custom efilink utility.
* [pxe] Display PXE_LOADER debug message after call to initialise()Michael Brown2008-09-231-3/+3
| | | | | | | At least one Dell system calls the UNDI loader entry point with the BIOS console disabled. The serial console is active only after a call to initialise(), so move the debug message in undi_loader() so that it can be displayed via the serial console.
* [pxe] Add extra debug messages to the PXE UDP API callsMichael Brown2008-08-211-4/+16

* [pxe] Fix broadcast transmissions via PXENV_UDP_WRITEMichael Brown2008-08-211-0/+1
| | | | | pxenv_udp_write() needs to specify a net device, otherwise ipv4 is unable to route broadcast transmissions.
* [undi] Fill in ProtType correctly in PXENV_UNDI_ISRMichael Brown2008-08-201-12/+61
| | | | | | | | | Determine the network-layer packet type and fill it in for UNDI clients. This is required by some NBPs such as emBoot's winBoot/i. This change requires refactoring the link-layer portions of the gPXE netdevice API, so that it becomes possible to strip the link-layer header without passing the packet up the network stack.
* [undi] Work around broken UNDI polling behaviour in winBoot/iMichael Brown2008-08-201-3/+17
| | | | | | | | Some dumb NBPs (e.g. emBoot's winBoot/i) never call PXENV_UNDI_ISR with FuncFlag=PXENV_UNDI_ISR_START; they just sit in a tight polling loop merrily violating the PXE spec with repeated calls to PXENV_UNDI_ISR_IN_PROCESS. Force a extra calls to netdev_poll() to cope with these out-of-spec clients.
* [iSCSI] Support Windows Server 2008 direct iSCSI installationMichael Brown2008-07-171-1/+1
| | | | | | | | | | | | | Add yet another ugly hack to iscsiboot.c, this time to allow the user to inhibit the shutdown/removal of the iSCSI INT13 device (and the network devices, since they are required for the iSCSI device to function). On the plus side, the fact that shutdown() now takes flags to differentiate between shutdown-for-exit and shutdown-for-boot means that another ugly hack (to allow returning via the PXE stack on BIOSes that have broken INT 18 calls) will be easier. I feel dirty.
* [i386] Change semantics of __from_data16 and __from_text16Michael Brown2008-07-013-8/+4Star
| | | | | | | | | __from_data16 and __from_text16 now take a pointer to a .data16/.text16 variable, and return the real-mode offset within the appropriate segment. This matches the use case for every occurrence of these macros, and prevents potential future bugs such as that fixed in commit d51d80f. (The bug arose essentially because "&pointer" is still syntactically valid.)
* [pxe] Fix a typo in PXENV_GET_CACHED_INFO that broke AltirisMichael Brown2008-07-011-1/+1
| | | | | | __from_data16 takes the value pointed to, rather than the pointer itself. This was silently causing gPXE to return a dud buffer pointer when the caller did not supply a buffer for PXENV_GET_CACHED_INFO.
* [misc] Fix building on OpenBSDMichael Brown2008-06-271-1/+1
| | | | | | | OpenBSD throws compiler warnings that we can't reproduce on Linux, for some reason. Original patch from Dewey Hylton <dewey@hyltown.com>.
* [PXEXT] Add FILE_API_CHECK API functionH. Peter Anvin2008-03-261-0/+35
| | | | | 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 Brown2008-03-251-4/+4
| | | | | | | | | | | | 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.
* [DHCP] Fix up fake-packet creation as used by PXENV_GET_CACHED_INFOMichael Brown2008-03-231-25/+34
| | | | | | | | | | | 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] Migrate DHCP and NVO code to the new settings API (untested)Michael Brown2008-03-211-7/+8
|
* [PXE] Work around a buffer-size bug in WinPEMichael Brown2008-03-101-2/+12
| | | | | | | | | | | WinPE's pxeboot.n12 takes the BufferLimit returned by gPXE (indicating the size of gPXE's internal DHCP packet buffers) and erroneously passes it in as BufferSize (indicating the size of pxeboot.n12's DHCP packet buffer). If these don't match, then pxeboot.n12 ends up instructing gPXE to overwrite parts of its data segment. Change gPXE's internal DHCP packet buffers to be exactly sizeof(BOOTPLAYER_t) bytes to work around this problem.
* [PXEXT] Add PXENV_FILE_EXEC call to PXE extensions API.Michael Brown2008-03-041-1/+39
| | | | | | | | 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.
* Start restructuring pxe_tftp.c to cope with multicast (MTFTP) receives.Michael Brown2008-02-021-147/+231
