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.

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
the copy in flat real mode.
 2006-05-25 00:04:13 +00:00
Michael Brown f939ff7cb5 Fix printf format warning error 2006-05-25 00:02:27 +00:00
Michael Brown 3bd3c13c7b Why should pushal/popal put the registers on the stack in a logical 
order?
 2006-05-25 00:01:46 +00:00
Michael Brown dd75965057 Typo. 2006-05-25 00:00:53 +00:00
Michael Brown e4f8d6eed7 Add a "count" field to struct memory_map. 2006-05-25 00:00:30 +00:00
Michael Brown 986f6ffff1 Define a struct memory_map with a fixed number of entries, rather than 
requiring each caller to decide how many entries it wants to permit.
 2006-05-24 14:41:27 +00:00
Michael Brown edcf89e2b0 Remove the automatic segment register save and restore; most users of 
REAL_CODE() don't need it.
 2006-05-24 14:11:36 +00:00
Michael Brown 02cf755f3f Removed REAL_EXEC(); there is no longer any code using it. 2006-05-24 14:10:15 +00:00
Michael Brown 103aff3ae2 Added potentially required "\n\t" on the end of asm_code_str 2006-05-24 14:06:28 +00:00
Michael Brown 190276a8b6 NBI is due for removal 2006-05-24 13:53:35 +00:00
Michael Brown 52125e158c Will be replaced with a block-device implementation. 2006-05-24 13:52:46 +00:00
Michael Brown 8110f9b082 Updated to REAL_CODE() 2006-05-24 13:50:40 +00:00
Michael Brown 595f161b51 Updated to REAL_CODE(). 
int13_boot() now does its own segment register save and restore, ready
for the removal of segment register restoration from the libkir
generic code.
 2006-05-24 13:48:16 +00:00
Michael Brown e8550035af Updated to REAL_CODE() 2006-05-24 13:28:39 +00:00
Michael Brown c4d688c005 Updated to REAL_CODE(). 2006-05-24 13:24:22 +00:00
Michael Brown 04d6005d77 Update to REAL_CODE() 2006-05-24 12:45:50 +00:00
Michael Brown 6631f46999 Updated to REAL_CODE(). 2006-05-24 12:32:57 +00:00
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) 
- 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
Michael Brown 95956443e1 Fixed debug code 2006-05-21 16:04:41 +00:00
Michael Brown 9dfb9d84b4 Made the LBA48 example clearer. 2006-05-21 16:02:38 +00:00
Michael Brown 80958ff69c Added (untested) support for ATA devices. This code should be generic 
enough to support both real IDE chipsets and AoE.
 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)
 2006-05-20 15:33:32 +00:00
Michael Brown af4aacb978 Added missing @file block 2006-05-20 13:25:07 +00:00
Michael Brown 4d0a0f822d Use insb/outsb; it's marginally faster. 2006-05-20 12:28:44 +00:00
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
use READ CAPACITY (16) if the READ CAPACITY (10) returns "out of range".
 2006-05-19 18:54:38 +00:00
Michael Brown 444b885a7d Add EOVERFLOW==ERANGE 2006-05-19 18:53:12 +00:00
Michael Brown b9cbae58fa Expert advice tells me that we *do* have to explicitly state the 
options even when we want to use the defaults.
 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 
about format errors for %zX arguments.
 2006-05-19 14:51:59 +00:00
Michael Brown c69c1ec540 Documented login parameters that we negotiate. 2006-05-19 00:31:42 +00:00
Michael Brown a280587cde iSCSI writes seem to be working (at least, the ethereal trace shows no 
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 b531bd2bda All uses iscsi_state were removed some time ago; removing the 
declaration.
 2006-05-18 21:38:16 +00:00
Michael Brown 53b682f3a2 Re-enable -Wformat, since our printf() is now more standards-conformant. 2006-05-18 21:23:38 +00:00
Dan Lynch 2814681d20 all window primitives implemented 2006-05-18 17:51:19 +00:00
Michael Brown 813a052dc3 Set ErrorRecoveryLevel=0 (we don't want to have to handle it). 2006-05-17 17:41:50 +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 6b514393d3 Change movetoyx(), putc() and getc() to methods of the screen. 2006-05-15 09:51:18 +00:00
Dan Lynch a2799051b0 fixed build error (danjlynch, repeat: this is *not* perl, this is *not* perl...) 2006-05-15 09:34:27 +00:00
Dan Lynch dccc6aed3a lightweight xcurses implementation for etherboot (Michael made me do it...) 2006-05-15 09:29:48 +00:00
Michael Brown 295e11b2b0 Add INT 13,41 (extensions installation check). LILO's MBR now uses 
linear calls to load the MS-DOS boot sector in my test setup.
 2006-05-14 23:46:28 +00:00
Michael Brown f25731d08f Split "iSCSI as a SCSI device" out from "iSCSI as a TCP protocol". 2006-05-14 23:29:16 +00:00
Michael Brown 29fb77b0a4 Fix a couple of minor typos. 2006-05-14 18:17:29 +00:00
Michael Brown 6e42cb95bd Also capture INT 19 as a failure path, to allow for boot sectors that 
don't conform to BBS (e.g. the one created by mkdosfs).
 2006-05-14 14:13:55 +00:00
Michael Brown 4435667a00 Add int13_boot(), to allow booting from INT 13 emulated drives. 2006-05-14 13:44:47 +00:00

Michael Brown eb6b8e8d70 Handle the '"%c", 0' case correctly. 2006-05-14 11:55:30 +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

Avoid optimisation errors under -fstrict-aliasing.
 2006-05-13 11:10:24 +00:00
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.

Michael Brown f8e087767b Allow access to variables in .text16 as well as .data16. Chained 
interrupt vectors, for example, will be easiest to handle if placed in
.text16.

Michael Brown dcc1b0054e This line should not have been checked in 2006-05-04 23:22:42 +00:00
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 
.data16.  librm will need to supply "char *data16", i.e. the virtual
address of the start of .data16.

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.

Michael Brown 10c28a51bd Create two easy-to-use entry points in libprefix: install and 
install_prealloc.  I *think* these will suffice for all the 16-bit
prefixes.
 2006-05-02 20:51:07 +00:00
Michael Brown 9e1dd6402d <name>_size variable is no longer needed, since we don't copy the code. 
However, it's worth adding a .size directive so that objdump reports the
correct sizes for the code fragments.

Michael Brown d081d65d48 This should be much more elegant: we use flat real mode for the 
highmem data, so decompress16 will be able to unpack blocks bigger
than 64kB.
 2006-05-01 22:35:19 +00:00
Michael Brown cc8821a443 Checking in because I don't want to lose this rather neat code for 
running the decompresser in 16:16 protected mode using the real-mode
stack.  However, there's an even simpler way to do it...

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.

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

fls(), flsl(), ffs() and ffsl() appear in strings.h according to
POSIX.

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.

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.  :)

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 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.

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 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 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.
