* [job] Report progress of downloader jobs via job_progress()Michael Brown2009-08-311-2/+21
|
* [job] Add missing job_progress() interface methodMichael Brown2009-08-311-0/+8
|
* [infiniband] Add support for SRP over InfinibandMichael Brown2009-08-101-0/+3
| | | | | | | | SRP is the SCSI RDMA Protocol. It allows for a method of SAN booting whereby the target is responsible for reading and writing data using Remote DMA directly to the initiator's memory. The software initiator merely sends and receives SCSI commands; it never has to touch the actual data.
* [process] Make it safe to call process_add() multiple timesMichael Brown2009-08-101-3/+10
|
* [debug] Use a delimiter to break up DBG_HD() outputMichael Brown2009-07-171-1/+2
| | | | | Reading sixteen columns of hex digits can be difficult; include a "-" character to split the output into two groups of eight columns.
* [xfer] Always nullify interface while sending close() messageMichael Brown2009-07-062-5/+3Star
| | | | | | | | | | | | | | | Objects typically call xfer_close() as part of their response to a close() message. If the initiating object has already nullified the xfer interface then this isn't a problem, but it can lead to unexpected behaviour when the initiating object is aiming to reuse the connection and so does not nullify the interface. Fix by always temporarily nullifying the interface during xfer_close() (as was already being done by xfer_vreopen() in order to work around this specific problem).

* [pxe] Add startpxe and stoppxe commandsMichael Brown2009-06-281-0/+3
| | | | | | | | | These commands can be used to activate or deactivate the PXE API (on a specifiable network interface). This is currently of limited use, since most image formats will call shutdown() before booting the image, meaning that the underlying net device gets shut down during remove_devices() anyway.
* [settings] Fix setting_cmp() to handle nameless settingsShao Miller2009-06-131-2/+6
| | | | | | | | | | setting_cmp() compares by option tag and then by name. Empty names will always match, which gives us a false positive. Fix by explicitly checking for empty names. Modified-by: Michael Brown <mcb30@etherboot.org> Signed-off-by: Michael Brown <mcb30@etherboot.org>
* [script] Allow for DOS-style line endings in scriptsMichael Brown2009-06-033-16/+52
| | | | | | | | | | | | | | | Windows text editors such as Notepad tend to use CRLF line endings, which breaks gPXE's signature detection for script images. Since scripts are usually very small, they end up falling back to being detected as valid PXE executable images (since there are no signature checks for PXE executables). Executing text files as x86 machine code tends not to work well. Fix by allowing for any isspace() character to terminate the "#!gpxe" signature, and by ensuring that CR characters get stripped during command line parsing.

* [settings] Allow for arbitrarily-named settingsMichael Brown2009-05-261-55/+241
| | | | | This provides a mechanism for using arbitrarily-named variables within gPXE, using the existing syntax for settings.
* [settings] Fix erroneous bit-masking in fetch_uintz_setting()Michael Brown2009-05-201-1/+2
|
* [legal] Add a selection of FILE_LICENCE declarationsMichael Brown2009-05-1842-0/+84
| | | | | Add FILE_LICENCE declarations to almost all files that make up the various standard builds of gPXE.
* [gdb] Allow resynchronisation with gdbStefan Hajnoczi2009-04-151-6/+4Star
| | | | | | | | | This replaces the gdbstub's polite NAK behavior with retransmission of the current outstanding reply packet. It solves situations where gdb and gPXE's gdbstub get out of sync due to the lack of flow control in the gdb protocol spec. Signed-off-by: Michael Brown <mcb30@etherboot.org>
* [resolv] Simplify xfer_redirect() logicMichael Brown2009-03-301-11/+30
| | | | | Now that we have xfer_vreopen() as the default .vredirect handler, sending redirection events can become simpler.
* [xfer] Implement xfer_vreopen() to properly handle redirectionsMichael Brown2009-03-303-2/+30
| | | | | When handling a redirection event, we need to close the existing connection before opening the new connection.

* [tables] Incorporate table data type information into table definitionMichael Brown2009-03-131-2/+2
| | | | | | | Eliminate the potential for mismatches between table names and the table entry data type by incorporating the data type into the definition of the table, rather than specifying it explicitly in each table accessor method.
* [tables] Redefine methods for accessing linker tablesMichael Brown2009-03-1311-108/+20Star
| | | | | | | | | | | | | | | 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.
* [time] Add the time commandDaniel Verkamp2009-03-061-0/+3

* [settings] Allow for autovivification of settings blocksMichael Brown2009-03-061-51/+113
| | | | | | | | | | | | | | | | | | Allow for settings blocks to be created on demand. This allows for constructions such as set defaults/filename http://bootserver/bootfile set defaults/priority 0xff dhcp net0 chain ${filename} which will boot from the DHCP-provided filename, or from "http://bootserver/bootfile" if the DHCP server does not provide a filename. (Note that "priority" gets interpreted as a signed integer, so setting "defaults/priority" to 0xff will cause the "defaults" settings block to have an effective priority of -1.)
* [image] Allow for zero embedded imagesMichael Brown2009-02-241-6/+10
| | | | | | | | | | | | | | | | | | Having a default script containing #!gpxe autoboot can cause problems when entering commands to load and start a kernel manually; the default script image will still be present when the kernel is started and so will be treated as an initrd. It is possible to work around this by typing "imgfree" before any other commands, but this is counter-intuitive. Fix by allowing the embedded image list to be empty (in which case we just call autoboot()), and making this the default. Reported by alkisg@gmail.com.
* [login] Add "login" command and UIMichael Brown2009-02-171-0/+3

* [settings] Allow store_setting() to access the root settings blockMichael Brown2009-02-171-3/+3
|
* [comboot] Fix reference counting on replacement imagesMichael Brown2009-02-171-2/+1Star
| | | | When chaining COMBOOT images, the old images now get freed correctly.
* [comboot] Allow for tail recursion of COMBOOT imagesMichael Brown2009-02-171-3/+27
| | | | | | | | | | | | Multi-level menus via COMBOOT rely on the COMBOOT program being able to exit and invoke a new COMBOOT program (the next menu). This works, but rapidly (within about five iterations) runs out of space in gPXE's internal stack, since each new image is executed in a new function context. Fix by allowing tail recursion between images; an image can now specify a replacement image for itself, and image_exec() will perform the necessary tail recursion.
* [uri] Allow use of relative URIs when calling churi()Michael Brown2009-02-161-1/+4
|
* [image] Allow multiple embedded imagesMichael Brown2009-02-162-4/+12
| | | | | | | | | | This patch extends the embedded image feature to allow multiple embedded images instead of just one. gPXE now always boots the first embedded image on startup instead of doing the hardcoded DHCP boot (aka autoboot). Based heavily upon a patch by Stefan Hajnoczi <stefanha@gmail.com>.
* [xfer] Make consistent assumptions that xfer metadata can never be NULLMichael Brown2009-02-151-2/+9
| | | | | | | | | | | | | The documentation in xfer.h and xfer.c does not say that the metadata parameter is optional in calls such as xfer_deliver_iob_meta() and the deliver_iob() method. However, some code in net/ is prepared to accept a NULL pointer, and xfer_deliver_as_iob() passes a NULL pointer directly to the deliver_iob() method. Fix this mess of conflicting assumptions by making everything assume that the metadata parameter is mandatory, and fixing xfer_deliver_as_iob() to pass in a dummy metadata structure (as is already done in xfer_deliver_iob()).
* [base64] Add base64 encoding functionsMichael Brown2009-02-131-0/+66
|
* [settings] Handle errors in fetchf_uristring()Michael Brown2009-02-121-1/+4
| | | | | | | | | fetchf_uristring() was failing to handle error values from fetch_setting(), resulting in its attempting to allocate extremely large temporary buffers on the stack (and so overrunning the stack and locking up the machine). Problem reported by Shao Miller <Shao.Miller@yrdsb.edu.on.ca>.
* [settings] Avoid duplicate settings block namesMichael Brown2009-01-311-0/+5
| | | | | | | Automatically unregister any settings with the same name (and position within the settings tree) as a newly registered settings block. This functionality is generalised out from dhcp.c.
* [settings] Add fetch_string_setting_copy()Michael Brown2009-01-271-0/+32
|
* [console] Allow KEY_xxx constants to cover F8 function keyMichael Brown2009-01-251-6/+8
| | | | | | | F8 is represented by the ANSI escape sequence "^[[19~", which is not representable as a KEY_xxx constant using the current encoding scheme. Adapt the encoding scheme to allow F8 to be represented, since PXE requires that we may need to prompt the user to press F8.
* [main] Print an "initialising devices" bannerMichael Brown2009-01-081-0/+3
| | | | | | | | | | | Some devices take a very long time to initialise. This can make it difficult to visually distinguish between the error cases of failing to start executing C code and failing to initialise a device. Add a "gPXE initialising devices..." message. The trailing ellipsis indicates to the user that this may take some time, and the presence of the message indicates to the developer that relocation etc. all succeeded.
* [i386] Move iSCSI and AoE boot code to arch/i386/interface/pcbiosMichael Brown2008-11-192-454/+0Star
|
* [i386] Change [u]int32_t to [unsigned] int, rather than [unsigned] longMichael Brown2008-11-192-3/+3
| | | | | | 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.
* [i386] Rename __cdecl to __asmcallMichael Brown2008-11-191-1/+1
| | | | | __cdecl is a misleading name, since it currently encapsulates both cdecl and regparm(0) attributes. Rename to __asmcall.
* [settings] Ensure fetch_string_setting() returns a NUL-terminated stringMichael Brown2008-11-071-0/+1
| | | | | | | | | | | | | | | This fixes a regression introduced in commit 612f4e7: [settings] Avoid returning uninitialised data on error in fetch_xxx_setting() in which the memset() was moved from fetch_string_setting() to fetch_setting(), in order that it would be useful for non-string setting types. However, this neglects to take into account the fact that fetch_string_setting() shrinks its buffer by one byte (to allow for the NUL) before calling fetch_setting(). Restore the memset() in fetch_string_setting(), so that the terminating NUL is guaranteed to actually be a NUL.
* [romprefix] Add vendor branding facilities and guidelinesMichael Brown2008-10-311-2/+14
| | | | | | | | | | | | | Some hardware vendors have been known to remove all gPXE-related branding from ROMs that they build. While this is not prohibited by the GPL, it is a little impolite. Add a facility for adding branding messages via two #defines (PRODUCT_NAME and PRODUCT_SHORT_NAME) in config/general.h. This should accommodate all known OEM-mandated branding requirements. Vendors with branding requirements that cannot be satisfied by using PRODUCT_NAME and/or PRODUCT_SHORT_NAME should contact us so that we can extended this facility as necessary.
* [settings] Add the notion of a "tag magic" to numbered settingsMichael Brown2008-10-302-1/+2
| | | | | | | | | | | | | | | | | | | 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.
* [uri] Avoid interpreting DOS-style path names as opaque URIsMichael Brown2008-10-241-2/+6
| | | | | | | | | | A DOS-style full path name such as "C:\Program Files\tftpboot\nbp.0" satisfies the syntax requirements for a URI with a scheme of "C" and an opaque portion of "\Program Files\tftpboot\nbp.0". Add a check in parse_uri() to ignore schemes that are apparently only a single character long; this avoids interpreting DOS-style paths in this way, and shouldn't affect any practical URI scheme.
* [settings] Avoid returning uninitialised data on error in fetch_xxx_setting()Michael Brown2008-10-221-5/+15
| | | | | | | | | | Callers (e.g. usr/autoboot.c) may not check the return values from fetch_xxx_setting(), assuming that in error cases the returned setting value will be "empty" (for some sensible value of "empty"). In particular, if the DHCP server did not specify a next-server address, this would result in gPXE using uninitialised data for the TFTP server IP address.
* [efi] Add EFI image format and basic runtime environmentMichael Brown2008-10-131-0/+6
| | | | | | | | | 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.
* [sanboot] Quick and dirty hack to make SAN boot protocols selectableMichael Brown2008-10-131-0/+11
|
* [monojob] Release reference on completed jobMichael Brown2008-10-131-0/+1
| | | | | | monojob_wait() was holding a reference to the completed job, meaning that various objects would not be freed until the next job was plugged in to the monojob interface.
* [timer] Remove now-obsolete references to TIMER_BIOS and TIMER_RDTSCMichael Brown2008-10-131-10/+0Star
|
* [nap] Formalise the CPU sleeping APIMichael Brown2008-10-133-6/+5Star
|
* [monojob] Allow for extremely slow system timersMichael Brown2008-10-121-1/+1
| | | | | The EFI timer runs at one tick per second, so using ">" rather than ">=" results in a two-second gap between dots.
* [timer] Formalise the timer APIMichael Brown2008-10-122-84/+13Star
| | | | | | We now have two implementations for the timer API: one using the time-of-day counter at 40:70 and one using RDTSC. Both make use of timer2_udelay().
