multiple option sources (e.g. multiple DHCP replies, non-volatile
storage etc.)
 2006-06-27 17:24:07 +00:00

Michael Brown 3a660f9b25 Update ftp.c and hello.c to use the generic async_operations API. 2006-06-19 15:46:58 +00:00
Michael Brown 15397db2b4 Placeholder 2006-06-17 23:34:48 +00:00
Michael Brown 8637834031 Made the temporary buffer part of the TCP senddata() API, to ease the 
transition away from uIP.

Prepared ipv4.c for transition away from uIP.
 2006-06-17 23:20:54 +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 d393e61d8a Temporary hack to work around the "TX overflow" problem in the interim 
period before updating to the new driver API (which can cope with
having TX packets in progress).
 2006-06-16 14:38:16 +00:00
Michael Brown 52de4935f9 Add 4 bytes to maximum frame length to allow for the frame checksum. 
(This actually matters once you try using TCP, because you *will*
receive full-sized frames.)
 2006-06-16 14:30:41 +00:00
Michael Brown 7c76791730 Improve debugging output for legacy wrapper 2006-06-16 14:27:04 +00:00
Michael Brown e5865e796b Forward-port event queue fixes from 5.4 tree. 2006-06-16 14:05:43 +00:00
Michael Brown a20c565ef3 Forward-port start-of-day fixes from 5.4 tree 2006-06-16 14:03:43 +00:00
Michael Brown 50ab8c0e5b Forward-port reset-related changes from 5.4 tree. 2006-06-16 14:00:43 +00:00
Michael Brown 968501e323 For consistency 2006-06-16 13:17:40 +00:00
Michael Brown bcdcd796fb 32kB window is actually larger than our typical receive ring size. 
Shrink to 4kB for now.  We might want to see if it can be made
genuinely indicative of the RX ring size in the new TCP
implementation.
 2006-06-16 13:16:59 +00:00
Michael Brown bbd9e28061 Simplify TX datapath. 2006-06-16 00:19:46 +00:00
Michael Brown cce2e47ff4 Added iSCSI boot test code 2006-06-14 17:00:25 +00:00
Michael Brown 3b51c719d3 Generalise three-wire interface to generic SPI interface. 
Update rtl8139 driver to instantiate an SPI interface with a three-wire
device attached.
 2006-06-14 00:22:50 +00:00
Michael Brown ab4f96e525 Move per-transition delays from generic bit-bashing layer to i2c layer 
(since SPI bit-bashing will require different delay semantics).
 2006-06-14 00:20:35 +00:00
Michael Brown 714641ae6d Translate between "0 = success" and "0 = failure" call standards. 2006-06-14 00:18:13 +00:00
Michael Brown 51a36f1cfb Change read_bit() to return 0 or -1UL, rather than 0 or 1. 2006-06-12 19:29:50 +00:00
Michael Brown 2e49441535 Updated debug message to reflect change in data structure. 2006-06-12 01:10:08 +00:00
Michael Brown 2138db36ca Add "addr32" required explicitly by older gas. 2006-06-12 01:07:43 +00:00
Michael Brown c10698b8b4 Add NULL_TRAP as a config option 2006-06-11 01:55:43 +00:00
Michael Brown 55bb40c39a Fix typo 2006-06-11 01:55:12 +00:00
Michael Brown df4b503a8c Added null trap code for debugging. (Must be included by adding 
--nulltrap to the make target at the moment.)
 2006-06-11 01:48:29 +00:00
Michael Brown 7ce44f7480 Update to use the generic i2c bit-bashing code. 2006-06-11 00:57:38 +00:00
Michael Brown 3ed40686c9 Added bit-bashing i2c interface code 2006-06-11 00:57:00 +00:00
Michael Brown 476d02051f Windows Server 2003 sulks if we feed it an empty region in base memory 
as a result of our memory map editing, so strip out any empty regions.
 2006-06-09 12:20:03 +00:00
Michael Brown 6fd1bd0510 Added missing check-in 2006-06-09 10:19:17 +00:00
Michael Brown e90b64d625 Added sketch of bit-bashing interface common code 2006-06-08 19:47:09 +00:00
Michael Brown 17eea9f933 Fix bug with >256 cylinders. 
Allow our functions to return a non-zero, non-error status (since the
INT 13 Extensions Check has to return the API version in the register
that is otherwise always used for the error code).

Report a non-zero API version from the INT 13 Extensions Check; GRUB
now uses extended reads.
 2006-06-08 19:28:08 +00:00
Dan Lynch ad1aca0634 - separated curses.c out into separate source files to optimise 
library use later on
- some small mods to existing functions
 2006-06-08 17:23:37 +00:00
Michael Brown 1697c78848 Legacy drivers cannot cope with multiple active devices. 2006-06-08 15:18:27 +00:00
Michael Brown fdf62528ca It's astonishing how long really fundamental bugs can survive without 
being noticed...
 2006-06-08 15:06:09 +00:00
Michael Brown 191a906338 Fix some remarkably obvious mistakes in pcidirect.h 2006-06-08 14:57:04 +00:00
Michael Brown 763b7e2ef9 We now have just romprefix, rather than having isaprefix and pciprefix 2006-06-06 15:41:21 +00:00
Michael Brown ef37f78cbe Cut out almost all the optional code paths, drastically simplifying the 
flow of control through this code.

We now always add PCI and PnP headers even for ISA ROMs; there's no harm
in doing so.

UNDI loader is still missing.
 2006-06-06 15:33:39 +00:00
Michael Brown e7eca7b7cb Code segment may not be writable; create the temporary pointer to the GDT 
on the stack.
 2006-06-06 15:30:28 +00:00
Michael Brown 46253ba618 Calculate _rom_size for the ROM prefix 2006-06-06 15:29:39 +00:00
Michael Brown 8d0c5f3302 Use byte 6 for the checksum, rather than byte 5. (Byte 5 may be part of 
the jmp instruction).
 2006-06-06 15:29:14 +00:00
Michael Brown 02df45352c Force pci.o to be included. 
Print warning message at probe time.
 2006-06-05 16:17:52 +00:00
Michael Brown 754cfdfcf4 Legacy drivers will not pad when necessary 2006-06-05 16:10:36 +00:00
Michael Brown 7826de3f7e PNIC doesn't auto-pad. 2006-06-05 16:10:14 +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
Michael Brown c3e41e6fd1 Added soon-to-be-requisite missing include. 2006-06-05 15:41:22 +00:00
Dan Lynch 34cfbf55a4 - added most slk functions 2006-06-05 15:03:11 +00:00
Michael Brown d78581297b Improve tcpdump legibility. 2006-06-01 19:23:52 +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 48fb6c6dc2 Updated retry timer mechanism to incorporate smoothed RTT estimation. 
AoE now uses the retry timer mechanism.
 2006-06-01 14:33:52 +00:00
Michael Brown 50415b3aca Make DBG_DISCARD correct 2006-06-01 12:11:09 +00:00
Michael Brown 1f394c2f7c Backing out last change; no immediate plans to make the whole block-device 
layer asynchronous, so keeping the sync/async boundary within aoedev.c
seems cleanest for now.
 2006-06-01 11:14:59 +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 d21fc3610f Added sample AoE test code to tree 2006-06-01 11:05:36 +00:00
Michael Brown f6d20bb0f4 Put in a method to get the MAC address for the AoE target. (It's not 
elegant, but it works).
 2006-05-31 19:12:17 +00:00
Michael Brown 99ef98d0bf ATA devices are now asynchronous. The ATA layer itself now performs the 
async_wait(), though we may wish to move this higher up the stack, and
consider making the block device model asynchronous.  (There is only a
marginal cost for synchronous devices, since they can simply call
async_done() before returning; async_wait() will work seamlessly in this
situation).
 2006-05-31 18:57:11 +00:00
Michael Brown cf96d325d8 Missing from previous checkin. 
This is the core portion of the async I/O interface.
 2006-05-31 18:45:43 +00:00
Michael Brown 68125bc441 Added generic asynchronous operations code. 
Removed data_in_len and data_out_len from ata_command structure; the
lengths are implied by the sector count and the presence of the data_in
or data_out pointers.

Changed AoE code to use subcommands by default, and made aoe_issue()
nonblocking (with completion via async_wait()).
 2006-05-31 14:34:17 +00:00
Michael Brown 73a449e96b Added drivers/ata directory (forgot to check this in previously). 2006-05-31 14:31:48 +00:00
Michael Brown 552b4a178e One bit of an ASCII character can make a big difference. 2006-05-29 21:00:00 +00:00
Michael Brown 1db1a6dad3 Added first sketch of a generic retry timer mechanism. The idea is to use 
these timer objects in AoE and UDP protocols (where there is no underlying
retransmission mechanism) without requiring each protocol to implement its
own individual retry logic.  Eventually, we should be able to use the same
timer code for TCP retransmissions as well.
 2006-05-29 14:55:07 +00:00
Michael Brown 6541338897 Handle multi-sector reads by splitting them into subcommands. 2006-05-29 08:25:31 +00:00
Michael Brown 9a2a52693d Initial AoE implementation. Limitations are: 
Cannot yet handle reads of more than two sectors

  No retransmission

  No way to find out a target's MAC address (this proof of concept uses
  broadcasts)

These limitations shall not last long!  :)
 2006-05-28 23:29:43 +00:00
Michael Brown 6f998cecb3 Use separate data-in and data-out buffers. 
Increase code simplicity at the expense of around 64 bytes.
 2006-05-28 23:26:42 +00:00
Michael Brown 6d6252067f Add ETH_P_AOE 2006-05-28 21:47:52 +00:00
Michael Brown 35b04b1514 Tidy up comment 2006-05-28 14:40:04 +00:00
Michael Brown 041a04335e Fixed assembly on old versions of gas 2006-05-28 14:21:29 +00:00
Michael Brown f743de4858 Added tcp_kick(). This speed up LILO and GRUB booting by almost two 
orders of magnitude.
 2006-05-27 19:01:20 +00:00
Michael Brown cd3ecac809 Avoid causing TX overflow on small TX queues. 2006-05-27 13:55:36 +00:00
Michael Brown 70ef6dbb7c Rewrote to use the new net driver API, the updated PCI API, and the 
generic three-wire serial device support for EEPROM access.
 2006-05-27 13:45:14 +00:00
Michael Brown 69b1f24a97 I have no idea how this ever worked before. 2006-05-27 13:43:56 +00:00
Michael Brown 6c50564724 Make PKB_ZLEN the minimum possible size of packet buffer (to allow for 
hardware that can't autopad).
 2006-05-27 13:39:45 +00:00
Michael Brown 1dbafa8950 Tidied up debugging messages 2006-05-27 13:38:49 +00:00
Michael Brown aa2468babe Added abstraction layer for a three-wire serial device (e.g. the EEPROM 
used on RTL8139 cards).
 2006-05-26 15:39:24 +00:00
Michael Brown 9f86754f90 Updated to work with libprefix. 2006-05-25 22:04:47 +00:00
Michael Brown 29340d7728 Documented the fact that the prefix can prot_call(main) without 
worrying about its stack being destroyed during the Etherboot run.
 2006-05-25 22:04:17 +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
Michael Brown 3204a1e941 Removed some obsolete INIT_XXX constants. 2006-05-25 01:09:06 +00:00
Michael Brown d82f71efd0 Also hide base memory region from E820 map. 2006-05-25 00:10:58 +00:00
Michael Brown 89da833c5d init_librm() and prot_call() are now real-mode far calls. 
install() now calls relocate(), moves the protected-mode code to the new
location, and calls hide_etherboot().
 2006-05-25 00:06:45 +00:00
Michael Brown 4d81b48504 Has been obsolete for a while. 2006-05-25 00:04:37 +00:00
Michael Brown 1966945a5d Update relocate() to work with get_memmap(). 
Change semantics; relocate() now just finds a suitable location; it
doesn't actually perform the relocation itself.  Code in libprefix does

Michael Brown 53935e9dc6 Set carry flag before calling INT 15,e801 and INT 15,e820. 
Ignore carry flag for INT 15,88; the Ralf Brown interrupt list says
that CF is unreliable for this call.
 2006-05-24 12:19:16 +00:00
Michael Brown 7a53d07027 Split out REAL_CODE() from REAL_EXEC(), preparatory to removing REAL_EXEC 
completely.
 2006-05-24 09:51:04 +00:00
Michael Brown 83d80d9e79 Remove references to obsoleted REAL_CALL from documentation. 2006-05-24 09:16:48 +00:00
Michael Brown 3b525385af Removed REAL_FRAGMENT and REAL_CALL, and left just REAL_EXEC (which is 
the only one we actually use).  This allows REAL_EXEC fragments to
contain proper references to constraints (e.g. "%w0"), rather than having
to force the use of specific registers.

Note that the "num_constraints" parameter is now completely obsolete, and
that we can probably reduce the syntax to something like
  __asm__ __volatile__ ( REAL_CODE ( "asm statements" )
                         : output constraints
                         : input constraints
                         : clobber );
which would look much more natural, and avoid the need to always specify
a clobber list.


Add userptr_t to libkir.h, to allow it to at least compile.
 2006-05-24 09:14:44 +00:00
Michael Brown 77a65075a6 Replaced memsizes.c with smaller memmap.c, taking advantage of __data16, 
and creating a memory map that's easier to work with than the E820 map.
 2006-05-24 01:37:46 +00:00
Michael Brown 5e80847827 Code to install the new E820 mangler (which doesn't require copying 
down to base memory, since it is now in the base-memory-resident
.text16 section).
 2006-05-23 23:47:05 +00:00
Michael Brown 897313007b Add __{text,data}16_array, since there's no way I can see to make the 
usual __{text,data}16 trick work with arrays.  gcc seems to accept the
__asm__ ( asmlabel ) only after the [] of the array declaration, not
before.
 2006-05-23 23:42:45 +00:00
Michael Brown 5ec2b2c251 Cope with regions bigger than 4GB. 
We now split e820 regions around ourselves, rather than just
truncating the e820 region.  This avoids the worst-case scenario of
losing all memory over 4GB.

It's more important to get the memory map right now that we're
expecting to still be loaded when the OS starts in several situations
(e.g. Linux with UNDI driver, any OS with iSCSI/AoE boot, etc.).
 2006-05-23 23:33:37 +00:00
Dan Lynch bef8874842 - implemented printw (formatted string output, a la printf)

Michael Brown 80958ff69c Added (untested) support for ATA devices. This code should be generic

 2006-05-21 16:01:23 +00:00
Michael Brown ca2519cea3 Refactored to reduce code size; now down from 1304 to 1105 bytes. 
Tidied up debug messages; the log now contains one line per INT 13
operation, looking like

 INT 13,08 (80): Get drive parameters
 INT 13,02 (80): Read: C/H/S 0/47/14 = LBA 0xb9e <-> 1084:0000 (count 106)

Michael Brown 402ba15c64 READ CAPACITY (16) turns out to be an optional command (even though 
READ(16) is mandatory); we must use READ CAPACITY (10) first and then

 2006-05-19 17:50:49 +00:00
Dan Lynch acf572905c - made some of the bit shifting attribute access simpler (in my mind) 
- added extern declarations for global vars
- removed comments from static inlines (too time consuming to do them
  all, considering all so far have been due to the ridiculous amount of
  redundancy within the API spec)
- removed a few more extern func decls for funcs that cannot be
  implemented at this time
 2006-05-19 16:22:10 +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
Michael Brown d48d0fb1bb Add the concept of a "user pointer" (similar to the void __user * in 
the kernel), which encapsulates the information needed to refer to an
external buffer.  Under normal operation, this can just be a void *
equivalent, but under -DKEEP_IT_REAL it would be a segoff_t equivalent.

Use this concept to avoid the need for bounce buffers in int13.c,
which reduces memory usage and opens up the possibility of using
multi-sector reads.

Extend the block-device API and the SCSI block device implementation
to support multi-sector reads.

Update iscsi.c to use user buffers.

Move the obsolete portions of realmode.h to old_realmode.h.

MS-DOS now boots an order of magnitude faster over iSCSI (~10 seconds
from power-up to C:> prompt in bochs).
 2006-05-19 15:06:51 +00:00
Michael Brown 0ab92faedb Use typeof(sizeof(...)) to define a size_t. This stops gcc complaining

errors; still need to verify data integrity).

SCSI response PDUs are handled: status and sense data (if available) are
returned via the scsi_command structure.

Updated iSCSI session parameter usage.
 2006-05-19 00:20:08 +00:00

Michael Brown 61d7b8a5ef Added missing drivers/scsi 2006-05-17 17:31:18 +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 6b6096d28b Strip down i386 PCI configuration space I/O to the bare minimum. A 
typical build will now include 880 bytes of PCI support code, compared to
2327 bytes in Etherboot 5.4.

(There is a slight cost of around 5 extra bytes per access to a
non-constant config space address; this should be an overall win.
Driver-specific accesses will usually be to constant addresses, for
which there is no additional cost.)
 2006-05-17 01:12:11 +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 fcdab6299c Missed a reference to heap.h. 2006-05-16 15:01:26 +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!  :)

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.

Michael Brown fdb983d473 Preserve the whole of %esp across prot_call(). We have to split this 
between the low half stored in the static variable rm_sp, and the high
half stored on the prot_call() stack, because:

  Just using the stack would screw up when a prot_call()ed routine
  executes a real_call(); it would have no way to find the current top of
  the RM stack.

  Extending rm_sp to rm_esp would not be safe, because the guarantee that
  rm_sp must return to the correct value by the time an external
  real-mode call returns applies only to %sp, not to %esp.
 2006-05-06 19:44:23 +00:00
Michael Brown f8e087767b Allow access to variables in .text16 as well as .data16. Chained

Michael Brown 832807726a Add infrastructure to support access to .data16 (and .text16) variables 
from protected-mode code.

Set up %ds to point to .data16 in prot_to_real, so that code specified
via REAL_EXEC() and friends can access variables in .data16.

Move most real-mode librm variables from .text16 to .data16.
 2006-05-04 23:14:06 +00:00
Michael Brown f4429533a6 Added methods for efficiently declaring and accessing variables in

Michael Brown 01bd78d62a Created net/tcp and moved hello.c there 2006-04-30 09:34:11 +00:00
Michael Brown 7af478b30d Make tcp_connect() void; it will eventually have no failure case. 2006-04-30 02:13:52 +00:00
Michael Brown 9c9208a132 Put the TCP connection periodic processing in tcp.c, where it belongs. 2006-04-30 02:08:42 +00:00
Michael Brown 178b0a7e5e Consistency 2006-04-30 01:35:01 +00:00
Michael Brown 592a5a99c8 Moved uIP and tcp.c from proto/ to net/ 2006-04-30 01:16:37 +00:00
Michael Brown 352bf1bda2 Move init.h to gpxe/init.h. 2006-04-30 01:08:52 +00:00
Michael Brown bac97eb979 Change semantics of network API so that packet-absorbing calls *always* 
take ownership of the packet, rather than doing so only if they return
success.  This breaks semantic compatibility with Linux's
hard_start_xmit() method, but means that we don't have to worry so much
about error cases.

Split mechanism of processing received packets (net_rx_process()) out
from policy (net_step()), preparatory to putting net_step() in a separate
object.
 2006-04-29 17:17:43 +00:00
Michael Brown 23c494d14e Added basic code for implementing co-operative multitasking. 
Yes, you really can do it in 65 bytes.
 2006-04-29 16:42:09 +00:00
Michael Brown 5fe31f1014 Give uIP a static IP address for proof-of-concept testing 2006-04-28 14:15:21 +00:00
Michael Brown 129c6c3968 Network layer now works as a proof of concept 2006-04-28 14:13:50 +00:00
Michael Brown 1488cd3b73 Fix a couple of broken assertions, and align the buffer correctly. 2006-04-28 14:09:31 +00:00
Michael Brown 79f64eea55 Transmit the buffer contents, not the buffer descriptor... 2006-04-28 14:08:41 +00:00
Michael Brown 51feeab445 Add an explicit failure debug message 2006-04-28 14:07:41 +00:00
Michael Brown 084f6b18f7 Exclude bin directory from tags generation. 
Create something that might be usable as a symbol list for bochs'
internal debugger.
 2006-04-28 14:07:08 +00:00
Michael Brown d8e99bf28f Gave up on adding POSIX errno's as required, and just added (almost) all 
of them in one go.

EBADIMG has been replaced by ENOEXEC, and EIMGRET by ECANCELED.
 2006-04-28 13:44:34 +00:00
Michael Brown cfae86f6c8 Glenn managed to shrink .text by 5 more bytes. 2006-04-25 21:48:16 +00:00
Michael Brown fee8b91015 D'oh 2006-04-25 12:56:18 +00:00
Michael Brown 7a82c3eca3 Added missing ssize_t 2006-04-25 12:55:23 +00:00
Michael Brown cf3783b4ca Actually, it's probably a good idea to have packet buffers avoid 4kB 
crossings.
 2006-04-25 12:11:36 +00:00
Michael Brown 00a1de964d Update to use POSIX-like API. 2006-04-25 12:04:07 +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 2f0d412210 Add __constant_flsl(), because it's useful for finding out the next 
power-of-two up from a given constant via
  ( 1 << fls ( constant - 1 ) )

fls(), flsl(), ffs() and ffsl() appear in strings.h according to
POSIX.
 2006-04-24 23:00:32 +00:00
Michael Brown a81f96998b Added missing headers required for compilation in Etherboot. 2006-04-24 19:35:10 +00:00
Michael Brown 455b76980f Added pkb_reserve(). 2006-04-24 19:34:51 +00:00
Michael Brown 26749951dc We have our own ARP layer now. 2006-04-24 19:19:13 +00:00
Michael Brown fcf765e42d Add missing {register,free}_netdev(). 
Tie into existing driver API; we'll fix that up soon.
 2006-04-24 18:44:50 +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 4c4e4de18f (librm_base-1b) is already an offset; no need to apply OFFSET(). 
Doing so, in fact, seems to expose an assembler bug; (a-b-0) is
apparently not the same as (a-b).  Go figure.
 2006-04-24 18:29:47 +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.
 2006-04-24 15:42:49 +00:00
Michael Brown 53f78346bf Network API now allows for multiple network devices (although the 
implementation allows for only one, and does so without compromising on
the efficiency of static allocation).

Link-layer protocols are cleanly separated from the device drivers.

Network-layer protocols are cleanly separated from individual network
devices.

Link-layer and network-layer protocols are cleanly separated from each
other.
 2006-04-24 15:38:53 +00:00

 2006-04-24 15:33:06 +00:00
Michael Brown 0d97f0d482 Obviate uip_init(); our bss is zeroed at startup already. 2006-04-24 15:31:02 +00:00
Michael Brown 5423f876fb Don't bother poisoning lists; it costs code size. 2006-04-24 15:28:56 +00:00
Michael Brown 1d7cfd5acf Prototype now clashes with the macro in arch/i386. 2006-04-24 15:27:58 +00:00
Michael Brown 510ccb2900 Added __constant_memcpy() based on version in Linux's string.h. 
Added memswap().
 2006-04-24 15:25:25 +00:00
Michael Brown b6b6a0b5fe First draft of a dynamic memory allocator 2006-04-24 15:21:18 +00:00
Michael Brown e323d1a29b Add "net" directory. 
Avoid including debug information in bin/%.s output, since the whole
point is to have easy-to-read assembler.
 2006-04-24 15:20:01 +00:00
Michael Brown 6209bd873a First sketch of a new net device API. 2006-04-19 12:07:46 +00:00
Michael Brown bdc8190c8d Remove the concept of the media-independent link-layer header and replace 
it with metadata in the pkb structure.  This is required since UNDI will
want to be able to parse the link-layer header without destroying it.
 2006-04-19 11:32:24 +00:00
Michael Brown b89ccac02d Updated to remove obsolete constants 2006-04-19 02:11:56 +00:00
Michael Brown 3ca7dbe7ca Added the concept of a network interface (a network-layer concept) as 
separate from a network device (a link-layer concept).
 2006-04-19 02:09:08 +00:00
Michael Brown d65a66606b Typo 2006-04-19 02:08:27 +00:00
Michael Brown 2558439ce4 First version, based on include/linux/list.h, stripped down to just 
those functions we are likely to need.

Still need to come up with a way of getting the linker to create
static lists using this linking mechanism.
 2006-04-19 02:05:50 +00:00
Michael Brown d24042f0bb Update now that if_ether.h has moved. 2006-04-19 01:56:10 +00:00
Michael Brown 4f3581e99c Added ENOENT and EAFNOSUPPORT 2006-04-19 01:54:53 +00:00
Michael Brown ab139ceda9 Added pkb_unput() and pkb_len(). 2006-04-19 01:54:24 +00:00
Michael Brown 744b895077 Make flags more efficient. 
Add 'raw' net_addr facility (needed for ARP).
 2006-04-19 01:53:49 +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 9f67ad9db0 First version. ARP protocol independence in less than the size of uIP's 
Ethernet-and-IPv4-only ARP module.  :)
 2006-04-19 01:43:56 +00:00
Michael Brown 363905e1b6 Add missing prototype 2006-04-19 01:42:33 +00:00
Michael Brown 02d342f38f First version 2006-04-19 01:42:03 +00:00
Michael Brown 0b561ce972 First sketch 2006-04-18 17:52:51 +00:00
Michael Brown 42b659f926 First version 2006-04-18 17:49:51 +00:00
Michael Brown 0864a73347 First version, based on the concepts in linux/skbuff.h 2006-04-18 17:47:01 +00:00
Michael Brown 1a60444fe4 Added netmask and gateway global options. 
Added iSCSI testing.
 2006-04-05 11:46:18 +00:00
Michael Brown 6446767258 First draft of iSCSI protocol support. Is capable of retrieving disk 
blocks.
 2006-04-05 11:44:56 +00:00
Michael Brown 9ea782d339 Make pcap_inject non-static, so that its prototype doesn't conflict with 
the real pcap_inject in the case where we do have it.
 2006-04-05 11:44:05 +00:00
Michael Brown c8a7133e9f Added tcp_buffer, to give applications a zero-cost place to build data to 
be transmitted.
 2006-04-05 11:43:01 +00:00
Michael Brown 988bb50979 Added set_netmask() and set_gateway() 2006-04-05 11:41:15 +00:00
Michael Brown ee058362fa We don't need to know anything about ARP 2006-03-24 17:39:05 +00:00
Michael Brown 90892d5ec7 Allow specifying the local IP address via --from. 2006-03-24 17:28:40 +00:00
Michael Brown b44332eb7d Split non-TCP portions of the stack out into ip.[ch]. 
Added set_ipaddr().
 2006-03-24 17:22:09 +00:00
Michael Brown 1c607470e3 Put in a substitute pcap_inject() function, since earlier versions of 
libpcap are lacking the function.  For now, we always use the
substitute version, since there's no easy way to determine whether or
not we need it.
 2006-03-24 16:43:12 +00:00
Michael Brown 7e61f38799 Moved "hello world" protocol implementation out of prototester.c and into 
the first standalong uIP-based protocol module.
 2006-03-23 22:37:05 +00:00
Michael Brown 508dcdb303 Added container_of(). This seems about the best place to put it, since 
the definition of it uses offsetof(), and the two concepts are related.
 2006-03-23 22:07:21 +00:00
Michael Brown 99032becce Pick up the gPXE include files when building prototester. 2006-03-23 21:35:20 +00:00
Michael Brown 2299435f1c Added prototype for inet_ntoa, even though we don't have the function 
yet, in order to allow prototester.c to compile.  It might be worth
changing all the uses of "%@" in printf to use "%s" and inet_ntoa
instead, in order to improve the portability of our code.
 2006-03-23 21:34:25 +00:00
Michael Brown a4a0244aa3 Moved uIP wrapper out of prototester.c and into proto/tcp.c. 2006-03-23 21:32:03 +00:00
Michael Brown 17c0253ca0 Add include/gpxe as a directory to scan. 
Exclude proto/uip, since uip.c and uip_arp.c both have global variables
called "c", which screws up doxygen's auto-generation of links to file
documentation when it encounters a file name such as "hello.c".
 2006-03-23 21:06:36 +00:00
Michael Brown 2bc7c746a6 Updated with "doxygen -u" from doxygen 1.4.4 2006-03-23 20:39:26 +00:00
Michael Brown 05b284399e Moved old tcp.h to old_tcp.h, to avoid name clash with new (uIP-based) 
tcp.h.
 2006-03-23 20:34:08 +00:00
Michael Brown af23ff8a24 Assertions are now handled via the POSIX-like <assert.h>. 2006-03-23 19:33:57 +00:00
Michael Brown 55497b3402 Added missing #endif 2006-03-23 19:23:25 +00:00
Michael Brown cb8e89de15 Added assert.h, with assert() defined (almost) as per POSIX, and 
linker_assert() defined as gPXE-specific.
 2006-03-23 17:28:51 +00:00
Michael Brown 531371efa2 Removed to make way for the uIP-based tcp.c. 2006-03-23 16:59:25 +00:00
Michael Brown dde1c5ad18 Moved include/in.h to include/gpxe/in.h, so that it can be included by 
prototester.
 2006-03-23 16:45:01 +00:00
Michael Brown eaf40883ff Add Makefile for hijack and prototester utilities. 2006-03-23 13:11:41 +00:00
Michael Brown 21c58729ae Add debug symbols to objects. (They will be stripped out of the final 
-Obinary build anyway, so it doesn't waste any space).
 2006-03-23 13:09:29 +00:00
Michael Brown b2c94b32fc Make the application state a void *. 2006-03-23 13:08:06 +00:00
Michael Brown 218c26ff2b Can now also print data sent by the remote side. 2006-03-23 13:06:08 +00:00
Michael Brown 0d506a5c6a Now capable of sending "Hello world!" via TCP. 2006-03-23 12:25:28 +00:00
Michael Brown 911486fe41 Added basic http-specific option parsing 2006-03-22 22:35:32 +00:00
Michael Brown 5263a5abf4 Started adding structure to allow for separate protocol tests, with 
individual options.

Created the embryonic beginnings of a cleanly separated driver and
protocol stack API.
 2006-03-22 21:25:35 +00:00
Michael Brown c32e83ad8d Skeleton version: contains device driver (connecting to network via 
hijack daemon) and a functional but very ugly and very primitive
wrapper around uIP.

This passes proof-of-concept testing; it successfully initiates a TCP
connection and responds to pings.
 2006-03-22 02:23:20 +00:00
Michael Brown bb37bd47f8 Added from uip-0.9/uip/uip_arp.[ch] 2006-03-22 02:14:55 +00:00
Michael Brown 417e896f0a Remove htons(); it is provided elsewhere in Etherboot 2006-03-22 01:25:43 +00:00
Michael Brown 1c7c24f21f Basic, functional-but-extremely-pessimal versions (taken from 
uip-0.9/unix/uip_arch.c).
 2006-03-22 01:24:13 +00:00
Michael Brown c5a9c38606 Terminate cleanly on SIGINT or SIGHUP 2006-03-21 17:48:33 +00:00
Michael Brown e072baeb8c Use libpcap API to send/receive packets. 
Include automatic filtering (based on source MAC address of first
transmitted packet).

Proven to successfully elicit a ping response from a remote host.
 2006-03-21 16:50:25 +00:00
Michael Brown 4485df516c Basic structure in place: can daemonise, listen on a Unix domain 
socket, accept new connections, open a network interface using libpcap
and forward (all) traffic.
 2006-03-21 02:25:30 +00:00

Michael Brown b2909e547d They can come back when they have someone to support them. 2006-03-17 14:13:09 +00:00
Michael Brown a2b15fd1fe GPXE code cleanup and purge. 2006-03-17 14:09:45 +00:00
Michael Brown cdf1511d3e Prefix semantics have changed 2006-03-16 19:28:38 +00:00
Michael Brown 0e611719d2 Add uip on HEAD; it's safe to build, since nothing links against it at the 
moment.
