this code.
 2007-08-09 17:44:20 -07:00
Michael Brown cfcc41d407 Set current working URI to be that of the executable image when 
executing any image, not just a script.  (This will enable pxelinux to
use relative URIs, should it wish to.)

Michael Brown d4947c05b2 Allow images to hold references to the originating URI. 
Some shuffling around of the image management code; this needs tidying up.

Michael Brown 4ce8d61a5c Import various libgcc functions from syslinux. 
Experimentation reveals that gcc ignores -mrtd for the implicit
arithmetic functions (e.g. __udivdi3), but not for the implicit
memcpy() and memset() functions.  Mark the implicit arithmetic
functions with __attribute__((cdecl)) to compensate for this.

(Note: we cannot mark with with __cdecl, because we define __cdecl to
incorporate regparm(0) as well.)

Michael Brown b34d4d0449 Separate the "is data ready" function of xfer_seek() into an 
xfer_window() function, which can return a scalar rather than a
boolean.

Michael Brown 438d1cc0b9 Should be using the generic device probe mechanism, when (if) they 
eventually get updated.
 2007-07-03 20:39:30 +01:00
Michael Brown fae10a7ca1 We don't actually use the reset functions anywhere, and nothing really 
provides them.
 2007-07-03 20:34:51 +01:00
Michael Brown fd86c819ba Use a linker-table based system to automatically mark and start up 
permanent processes, rather than requiring each one to have its own
initialisation function.

Michael Brown 6209d20779 Added monojob controller in lieu of a full working shell. 2007-06-28 14:53:12 +01:00
Michael Brown 73fe1ba9dd Kill off job::start() (it was only ever added as part of an aborted 
attempt at triggering TCP-related protocols to start).
 2007-06-28 01:09:45 +01:00
Michael Brown 07dc294de8 Update DHCP to use data-xfer interface (not yet tested). 2007-06-27 23:20:36 +01:00
Michael Brown f77815f2b1 Kill off hotplug.h and just make net devices normal reference-counted 
structures.

DHCP still broken and #if 0'd out.
 2007-06-27 14:48:31 +01:00

Michael Brown 95adce0ce1 Add concept of transfer metadata, to be used by UDP in order to 
implement sendto()/recvfrom() equivalents.
 2007-06-11 15:04:39 +01:00
Michael Brown b256900d4f Scripts temporarily deregister themselves while executing. This 
allows us to avoid execution loops without having to hack around the
image registration order.
 2007-06-09 19:00:34 +01:00
Michael Brown 2c569fb240 Allow xfer_open() to take a struct uri as well as a URI string. 2007-06-09 18:20:08 +01:00

Michael Brown 335b99a39d Move [v]ssnprintf() from iscsi.c into vsprintf.c; we need them 
elsewhere as well.
 2007-05-31 13:26:50 +00:00
Michael Brown 735e07268e Update HTTP to use data-xfer interface. 2007-05-29 15:37:09 +00:00

Michael Brown bc694ec768 Move increment/decrement debug messages to DBG2 level 2007-05-27 01:04:52 +00:00
Michael Brown a1210e4fca Eliminate PF_INET; just use the AF_INET from the struct sockaddr instead. 2007-05-26 20:41:23 +00:00
Michael Brown 10d0a1f8c7 Modify data-xfer semantics: it is no longer necessary to call one of 
request(), seek() or deliver_xxx() in order to start the data flow.
Autonomous generators must be genuinely autonomous (having their own
process), or otherwise arrange to be called.  TCP does this by
starting the retry timer immediately.

Add some debugging statements.
 2007-05-26 15:04:36 +00:00
Michael Brown 3601103381 Modify process semantics; rescheduling is now automatic. 
Add reference-counting to processes.

Add timer_running() test.
 2007-05-26 15:00:56 +00:00

Michael Brown 68dd826b86 Add alloc_iob() and free_iob(). (Direct search-and-replace 
equivalents for alloc_pkb() and free_pkb(), which will be retired in
due course).
 2007-05-18 14:45:16 +00:00
Michael Brown 86a948ccbe Added POSIX-style blocking I/O calls, for use by PXE TFTP API. 2007-05-18 14:19:22 +00:00
Michael Brown 59e738d756 Prefix all the open()-family routines with xfer_, to disambiguate them 
from the normal POSIX-style open()
 2007-05-18 14:16:06 +00:00
Michael Brown b1755462ab Do not hold self-references. This then avoids the problem of having to 
ensure that we only drop our self-reference exactly once.

To maintain the guarantee that an object won't go out of scope
unexpectedly while one of its event handlers is being called, the
event-calling functions now automatically obtain and drop extra
references.
 2007-05-15 16:53:46 +00:00
Michael Brown 5471bfbbbe Data-transfer interface should now be functionally complete. 2007-05-15 15:23:09 +00:00
Michael Brown 53da1f1402 Initial sketch for a downloader object 2007-05-01 00:09:19 +00:00

 2007-05-01 00:07:57 +00:00
Michael Brown a90a9adbd7 Clarify behaviour of plug() by using intf_put() and intf_get(). 2007-05-01 00:06:21 +00:00
Michael Brown 31f1bf4426 D'oh 2007-04-30 01:24:52 +00:00
Michael Brown 0898b0b3b1 Added plug_plug() 2007-04-30 01:23:01 +00:00
Michael Brown d40761d725 Add (and use) generic reference counter, to improve signal:noise ratio 
in code defining reference-counted objects.
 2007-04-29 23:53:39 +00:00
Michael Brown 36bfb6edbb Skeleton job control interface 2007-04-29 02:08:39 +00:00

download
 2007-01-29 04:19:45 +00:00
Michael Brown 1a79437888 Added async_block_progress() and default SIGUPDATE handler. 2007-01-29 04:15:24 +00:00
Michael Brown c42a384709 Moved most buffer debug messages to DBG2. 
Make expand_buffer() a non-inline function, so that we can add debug
messages.

Expandable buffers now don't *always* round up to the next power of two.
This allows e.g. loading a 137MB ISO image on a machine with only 256MB
RAM...

Michael Brown 13d9a660ca Zeroing out memory before using it can be so important. 2007-01-19 14:44:59 +00:00
Michael Brown d6909f65f0 Actually, it's probably safer *not* to leave child processes hanging 
around which still hold pointers to variables belonging to our parent...
 2007-01-19 14:20:41 +00:00
Michael Brown b6194b8cb9 Note that the SIGCHLD handler could be re-entered. 2007-01-19 14:10:13 +00:00
Michael Brown 1411876e26 Propagate return status code from last child to fail. 2007-01-19 14:00:51 +00:00
Michael Brown 4256b3338a Split random number generation out into core/random.c, and create the 
correct prototypes for srandom(), rand() and srand().
 2007-01-19 02:02:59 +00:00
Michael Brown f4c1e564a1 vsprintf.h is gPXE-specific; move it to include/gpxe 2007-01-19 01:17:23 +00:00

Michael Brown 8bb9f726a0 When an async operation dies, orphan its children. 2007-01-18 22:36:57 +00:00
Michael Brown 6d4e37cf42 Move include/malloc.h to include/gpxe/malloc.h, since everything in there 
is now gPXE-specific.  (The standard malloc() et al have been in stdlib.h
for a while).

Add free memory counter.
 2007-01-18 20:11:04 +00:00
Michael Brown c8b3e969a0 Allow buffers to be pre-expanded on demand. 2007-01-18 15:13:41 +00:00
Michael Brown 08da93a311 Reorder functions to more closely reflect the flow of control 2007-01-18 13:10:26 +00:00
Michael Brown 35776f481c Don't always zero memory in malloc(). This saves around 2us on a 
full-length PKB allocation.
 2007-01-18 12:54:18 +00:00
Michael Brown 0b11733b75 Replacement for fetch() which operates asynchronously and identifies 
protocols by URI scheme.
 2007-01-18 03:37:05 +00:00
Michael Brown 6601a7da6a Added async_uninit() to simplify failure paths. 2007-01-18 03:29:40 +00:00
Michael Brown 5a807994d8 Add utility function to parse port from URI 2007-01-18 03:28:55 +00:00
Michael Brown 9828181e3b Obsolete 2007-01-18 01:05:09 +00:00
Michael Brown 544fa25928 Rename e{malloc,realloc,free} to u{malloc,realloc,free}, to more obviously 
reflect the fact that they allocate and deallocate user memory (i.e.
things reached through a userptr_t).
 2007-01-16 08:36:42 +00:00
Michael Brown 4e20d73bb5 Gave asynchronous operations approximate POSIX signal semantics. This 
will enable us to cascade async operations, which is necessary in order to
properly support DNS.  (For example, an HTTP request may have to redirect
to a new location and will have to perform a new DNS lookup, so we can't
just rely on doing the name lookup at the time of parsing the initial
URL).

Anything other than HTTP is probably broken right now; I'll fix the others
up asap.
 2007-01-15 08:49:10 +00:00
Michael Brown ec75b269d3 Add missing include 2007-01-15 08:44:05 +00:00
Michael Brown 26166cf5e0 Added a URI parser that should be standards conformant. (It can certainly 
handle something as convoluted as

Michael Brown 98240d99f0 Do not go past the end of the argv[] array. 
This bug found by setting read and write watchpoints at NULL in bochs.
 2007-01-14 02:01:26 +00:00
Michael Brown dca369ddc3 Call hide_etherboot() from startup(), rather than requiring the prefix to 
do it.
 2007-01-14 00:53:56 +00:00
Michael Brown c2708df14a Make shutdown functions callable by OS image's exec methods. 2007-01-14 00:16:41 +00:00
Michael Brown beb941ed81 Rename "boot" to "autoboot" 2007-01-14 00:06:23 +00:00
Michael Brown f11900a9c6 I prefer IMAGE_XXX to XXX_IMAGE. 
Add IMAGE_PXE to use the new image format framework.  "kernel pxelinux.0"
now works.
 2007-01-13 17:28:51 +00:00
Michael Brown 3b77c7aa1b Hex dumps are now integrated into the DBG() framework. 2007-01-13 16:49:38 +00:00
Michael Brown ca3db0bf11 Added isspace() and made strtoul() accept whitespace, as per POSIX. 2007-01-12 19:11:28 +00:00
Michael Brown 83b7933f8a Damn it; my lovely resilient scheme falls down when you have a protocol 
that switches from line-oriented to byte-oriented partway through, such as
HTTP.
 2007-01-12 18:09:14 +00:00
Michael Brown 996b091b50 Added generic line-buffering code (a la stdio) 2007-01-12 17:08:37 +00:00
Michael Brown 5c72d9c4e0 Print image physical location in registration message. 2007-01-12 16:20:51 +00:00
Michael Brown 9952df9b52 Add "dhcp" command 2007-01-12 09:53:28 +00:00
Michael Brown e2c0055e23 Let ifmgmt.c take care of calling efree(), since it's the once which 
took out the contract to eventually call efree() when it called fetch().

Maintain the most recently loaded image at the start of the list, so that
imgautoselect() will pick it.
 2007-01-12 09:46:10 +00:00
Michael Brown 67aedf34fa Use systematic names for XXX_IMAGE. 
Add scripts as an image format (since it's trivial to do).
 2007-01-12 09:00:48 +00:00
Michael Brown eba3609e7f Add debug message 2007-01-12 08:57:51 +00:00
Michael Brown 5162f30028 Ignore comment lines. 
Avoid returning errors for comments and empty lines.
 2007-01-12 08:56:48 +00:00
Michael Brown 475d6d1f7c fetch() now knows nothing about struct image; it simply loads a file and 
returns the allocated buffer.
 2007-01-12 08:02:27 +00:00
Michael Brown 742f242863 Add free_image 2007-01-12 06:26:59 +00:00
Michael Brown 9817f93094 Add basic "fetch" and "imgstat" commands. 2007-01-12 06:05:27 +00:00
Michael Brown b9fea9cbac Added IMAGE_LOADED flag and find_image() 2007-01-12 06:03:02 +00:00
Michael Brown f15482d85f Added basename() to make automatically naming images easier. 2007-01-12 05:24:51 +00:00

Michael Brown 7bf94b5ad6 Allow for named images. 2007-01-11 23:45:18 +00:00
Michael Brown f59ad50504 Provide registration mechanism for loaded images, so that we can e.g. 
refer to them by name from the command line, or build them into a
multiboot module list.

Use setting image->type to disambiguate between "not my image" and "bad
image"; this avoids relying on specific values of the error code.
 2007-01-11 23:43:29 +00:00
Michael Brown 4fc9333159 Move include/image.h to include/gpxe/image.h 2007-01-11 16:04:36 +00:00

Michael Brown 3634e705b7 Remove osloader.c and replace with a prep_segment() that uses userptr_t 
and get_memmap() in image/segment.c
 2007-01-11 14:32:26 +00:00
Michael Brown fbfed96965 buffer.c should be using copy_{to,from}_user, rather than 
copy_{to,from}_phys.
 2007-01-11 05:42:06 +00:00
Michael Brown c0ef730ec4 Fix bug in buffer.c, add buffer mini-unit test. 2007-01-11 04:46:41 +00:00

Michael Brown d45c5e7ce7 Add "route" command (which currently only displays the routing table; it 
can't modify it).
 2007-01-10 20:51:14 +00:00
Michael Brown 77bb7b13a7 Having forced __table() to natural structure alignment, it now seems 
that we *can* place arrays in tables, which means we can force the
order within a table without having to resort to explicitly numbered
sections on everything.
 2007-01-10 05:08:05 +00:00
Michael Brown dad5274522 Add "name" field to struct device to allow human-readable hardware device 
names.

Add "dev" pointer in struct net_device to tie network interfaces back to a
hardware device.

Force natural alignment of data types in __table() macros.  This seems to
prevent gcc from taking the unilateral decision to occasionally increase
their alignment (which screws up the table packing).
 2007-01-10 04:22:09 +00:00
Michael Brown 55e590ab3a Move header file for usr/autoboot.c to include/usr 2007-01-10 02:03:20 +00:00
Michael Brown d24b80acf2 Added network interface management commands 2007-01-10 01:55:07 +00:00
Michael Brown 7b9617f5df Add device to hierarchy before calling the driver's probe() function; this 
way everything remains consistent if the probe() ends up creating child
devices.
 2007-01-08 01:29:51 +00:00
Michael Brown 0063725d28 Minimal hotplug support: provide a facility for notifying persistent 
reference holders that their reference is about to become invalid.
 2007-01-04 03:08:16 +00:00

Michael Brown c21502acad No longer needed 2006-12-20 07:13:46 +00:00
Michael Brown 84202d89f0 Split the (quick hack) boot logic out from main.c to autoboot.c, add a 
"boot" command to attempt booting from within the command shell, fall back
to shell if boot fails for any reason.
 2006-12-20 07:04:08 +00:00
Michael Brown 8f9336e0c1 Add "config" command to access config UI 2006-12-20 05:37:33 +00:00
Michael Brown 2b97d2ebc5 8-bit integers are 1 byte long, not 8... 2006-12-20 05:04:17 +00:00
Michael Brown b93ff48173 Added descriptive text for settings and setting types, and display it in 
the option config UI.
 2006-12-20 04:58:26 +00:00
Michael Brown 35edecac34 Move {show,set,clear}_setting() to {show,set,clear}_named_setting(). 
Introduce new {show,set,clear}_setting() that take a struct setting *
rather than a const char *.

set_setting() handles calling clear_setting() when appropriate, so that
individual setting types don't have to check for empty strings.
 2006-12-20 04:20:13 +00:00
Michael Brown 7766e34ed1 Split strerror() out from errno.c 2006-12-20 03:49:36 +00:00

command is linked in.
 2006-12-19 16:27:15 +00:00

in our commands.

completely forgot I'd written ages ago.

Michael Brown ab4e1dba3f Added nvo_save() 2006-12-04 22:04:10 +00:00
Michael Brown cc9bcb99a0 Add the concept of a fragment list for non-volatile stored options. 2006-12-04 21:46:13 +00:00
Michael Brown 946967f09c Abstracted out part of the concept of an SPI device to a generalised NVS 
device.

Separated the mechanisms of non-volatile storage access and non-volatile
stored options.
 2006-12-04 18:23:06 +00:00
Michael Brown 4cd56820ea Basic non-volatile storage support 2006-11-29 02:41:08 +00:00
Michael Brown c4677c7e73 Implemented realloc(), and changed the semantics of malloc(0) to allow 
for realloc(0) being a valid way to free memory.
 2006-11-24 16:51:18 +00:00
Michael Brown 6a18721ce8 Fixed off-by-one error 2006-11-22 04:54:17 +00:00

Michael Brown 5753f2c58b May as well add octal support to strtoul() 2006-11-15 02:57:24 +00:00
Michael Brown bbfb2e02fd Fixed endp bug in strtoul() 2006-11-15 02:54:28 +00:00
Michael Brown 65ff5357f1 Extend strtoul() to cope with hex as well as decimal. Doesn't cope 
with octal yet, but we can probably live without that.
 2006-11-15 02:52:06 +00:00
Michael Brown 88e38fa148 We don't actually have a stdio.h header file. Our printf() functions are 
defined in vsprintf.h.  (This may change, since vsprintf.h is a
non-standard name, but for now it's the one to use.)

There should be no need to include vsprintf.h just for DBG() statements,
since include/compiler.h forces it in for a debug build anyway.
 2006-09-27 10:58:14 +00:00
Marty Connor 6ac78f6aff added stdio.h to includes for DBG compilation 2006-09-27 05:57:06 +00:00

dependency on dev.o.

stack or INT 13 emulator etc.
 2006-08-14 22:29:51 +00:00
Michael Brown 3c35a0b16d Added cmdl_show proof-of-concept 2006-08-11 18:40:27 +00:00

Dan Lynch 446c1a3372 - deprecated in favour of a split library model 2006-06-27 11:05:13 +00:00
Michael Brown 3c8aafa209 Simplify RX data path. 
Kill off the static single net device and move to proper dynamic
registration (which we need with the new device model).

Break the (flawed) assumption that all network-layer protocols can use
ARP; such network-layer protocols (i.e. IPv4) must now register as an ARP
protocol using ARP_NET_PROTOCOL() and provide a single method for checking
the existence of a local network-layer address.
 2006-06-17 22:36:27 +00:00
Michael Brown 8aeead7c1c Remove dependency on arptable[] (which is no longer used). 2006-06-16 14:48:31 +00:00
Michael Brown c10698b8b4 Add NULL_TRAP as a config option 2006-06-11 01:55:43 +00:00
Michael Brown 286bf68faf Added a very quick and dirty compatibility layer, to allow 
not-yet-updated drivers to at least function.
 2006-06-05 15:45:21 +00:00
Dan Lynch 34cfbf55a4 - added most slk functions 2006-06-05 15:03:11 +00:00
Michael Brown 6ab4b99f41 Quick hack to avoid trying to use an uninitialised net device. 2006-06-01 15:53:05 +00:00
Michael Brown d6866202f9 Until we have a functioning UDP stack and PXE API again, there's not much 
point trying to use the old boot sequence.  Replaced with a call to the
AoE demo code, so that people can at least build and try something useful.
 2006-06-01 11:07:31 +00:00
Michael Brown cf96d325d8 Missing from previous checkin. 
This is the core portion of the async I/O interface.

Michael Brown 1dbafa8950 Tidied up debugging messages 2006-05-27 13:38:49 +00:00
Michael Brown 0479e9f541 relocate.o is now dragged in by the objects that require it; there is no 
need for a CONFIG_RELOCATE.
 2006-05-25 01:34:13 +00:00
Dan Lynch bef8874842 - implemented printw (formatted string output, a la printf) 
- implemented hline/vline (part of wborder family)
- screen cursor now relocates at same time as window cursor when
  restoring after a non-wrapping function
 2006-05-22 17:03:41 +00:00
Michael Brown 84a493b88d Allow vcprintf() to be called by external code such as the curses library. 
Also trim another eight bytes from vsprintf.o.  :)
 2006-05-22 15:41:01 +00:00
Dan Lynch f778500739 - fixes to _wputch to get positioning and wrap working properly 
- fixes to wborder (same)
- addition of a few minor functions
 2006-05-22 13:10:19 +00:00
Dan Lynch d166dc57ab - made _wputch wrap lines as well as cols (wraps back to line 0, as we have not way to scroll...) 
- implemented color_content, wborder, wblrtobot, wclrtoeol, wcolor_set and several small functions
- added rest of expected global variables
 2006-05-19 16:18:08 +00:00
Dan Lynch 2814681d20 all window primitives implemented 2006-05-18 17:51:19 +00:00
Michael Brown a4143e8c87 Split debug functions out into core/debug.c, so that they can be 
automatically linked in on demand.

Corrected warnings in misc.c.  strtoul() really should be
  unsigned long strtoul ( const char *p, const char **endp, int base )
but such is not the ANSI standard.
 2006-05-17 17:16:24 +00:00
Michael Brown 15ee09ed10 Restructured PCI subsystem to fit the new device model. 
Generic PCI code now handles 64-bit BARs correctly when setting
"membase"; drivers should need to call pci_bar_start() only if they want
to use BARs other than the first memory or I/O BAR.

Split rarely-used PCI functions out into pciextra.c.

Core PCI code is now 662 bytes (down from 1308 bytes in Etherboot 5.4).
284 bytes of this saving comes from the pci/pciextra split.

Cosmetic changes to lots of drivers (e.g. vendor_id->vendor in order to
match the names used in Linux).
 2006-05-16 15:12:06 +00:00
Michael Brown 0afa9db2de Tear out old heap code, replace with code that simply allocates memory 
for use by malloc().

This breaks the image-loading code (which previously used the heap to
allocate the buffer for downloading the image), but that's not a major
concern since I'm going to tear out all the image formats within the next
couple of days anyway.  Byebye, NBI!  :)
 2006-05-16 15:00:36 +00:00

Michael Brown efd6281a35 Correctly handle zero-length buffers. 2006-05-14 11:18:42 +00:00
Michael Brown 25f5d114a0 Updated documentation. 
Shaved around 100 bytes off vsprintf.o.  It's now 50 bytes smaller than
the old implementation and provides much more conformant semantics,
including the ability to return the number of characters that would have
been printed to the string had the buffer been big enough.  (iSCSI needs
this functionality).
 2006-05-14 03:31:20 +00:00
Michael Brown 2421723a15 Rewrote printf and friends to better support standard C semantics. 2006-05-14 02:51:55 +00:00
Michael Brown f99e7a375e At least cope with "%llx" by reading the correct-sized va_arg from the 
stack, even if we don't yet print it out.

At some point, vsprintf() needs to be fixed up so that it can correctly
cope with limited-sized buffers (i.e. vsnprintf), long longs, and
standard format specifiers (e.g. "%04x").  We should also remove the
special types (MAC addresses and IP addresses).  This would then enable
us to use gcc's ability to type-check printf format strings.
 2006-05-13 11:50:52 +00:00
Michael Brown f8f75cef5b BSS is now zeroed by libprefix (along with the otherwise non-zeroable 
portions such as the stack) during the installation process.

init_fns() are called from main().  We need to think about initial
control flow some more.
 2006-05-02 21:10:45 +00:00
Michael Brown a42092d2a0 Add a temporary snprintf, so that safely-written code can at least 
compile, even if it won't yet be safe.
 2006-04-30 12:01:31 +00:00

Michael Brown cfae86f6c8 Glenn managed to shrink .text by 5 more bytes. 2006-04-25 21:48:16 +00:00
Michael Brown face774c4c Fixed erroneous comparison 2006-04-25 11:54:58 +00:00
Michael Brown 95f8a42930 Removed incorrect comment; malloc() is inefficient only when the 
alignment and size are both powers of two, and there's no way to
specify an alignment through the malloc() interface anyway.
 2006-04-25 10:41:49 +00:00
Michael Brown 4e92f29c9e Now passes trivial tests. free_memblock() needs neatening up. 2006-04-25 04:01:58 +00:00
Michael Brown b601a7d355 Updated memory allocator to improve support for unaligned or partially 
aligned blocks.

Moved header to include/malloc.h, since we now also provide the
POSIX-like malloc()/free() pair.

Not yet tested.
 2006-04-25 03:30:46 +00:00
Michael Brown 832e86246b gcc is rather over-aggressive about optimising out static data structures 
even when __atribute__ (( unused )) is correctly set...
 2006-04-24 18:31:37 +00:00
Michael Brown 824d6ffa7f Header rearrangement. 
I want to get to the point where any header in include/ reflects a
standard user-level header (e.g. a POSIX header), while everything that's
specific to gPXE lives in include/gpxe/.  Headers that reflect a Linux
header (e.g. if_ether.h) should also be in include/gpxe/, with the same
name as the Linux header and, preferably, the same names used for the
definitions.

Michael Brown b6b6a0b5fe First draft of a dynamic memory allocator 2006-04-24 15:21:18 +00:00
Michael Brown d24042f0bb Update now that if_ether.h has moved. 2006-04-19 01:56:10 +00:00
Michael Brown 49f933fbc3 Moved if_ether.h and if_arp.h to include/gpxe, for consistency with Linux 
kernel.

Removed obsolete struct arprequest from if_arp.h and put it in nic.c so
that nic.c will still compile.  ARP will very shortly be handled by
net/arp.c instead.
 2006-04-19 01:52:41 +00:00

Michael Brown ab07740755 First version 2005-05-17 18:39:27 +00:00
Michael Brown ff9104e029 Added errno, strerror and the "%m" printf metacharacter. These will allow 
us to return proper PXE status codes, while simultaneously allowing for
more consistent error reporting (complete with verbose error messages as a
build-time option).

 2005-05-09 13:24:01 +00:00
Michael Brown ef05a27f25 Start of an implementation using doubly-linked lists and virtual
