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).

2421723a15 Rewrote printf and friends to better support standard C semantics. 2006-05-14 02:51:55 +00:00

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.

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.

f8e087767b Allow access to variables in .text16 as well as .data16. Chained

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.

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.

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.

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.

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

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.

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.

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.

devices.

Link-layer and network-layer protocols are cleanly separated from each

49f933fbc3 Moved if_ether.h and if_arp.h to include/gpxe, for consistency with Linux

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.

1c607470e3 Put in a substitute pcap_inject() function, since earlier versions of 
libpcap are lacking the function.  For now, we always use the

not we need it.

7e61f38799 Moved "hello world" protocol implementation out of prototester.c and into 
the first standalong uIP-based protocol module.

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.

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.

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".

2bc7c746a6 Updated with "doxygen -u" from doxygen 1.4.4 2006-03-23 20:39:26 +00:00

 2006-03-23 17:28:51 +00:00

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

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.
