8f8af10b22 New strategy: always stop both base code and UNDI. Always free base code 
memory (unless we get an error while stopping the base code).  Leave UNDI
resident (though stopped) for .kpxe.

Still need to add code to record the device identification parameters
prior to stopping UNDI.

6fc75f659b Separated out UNDI ROM location code into undirom.c, and use struct 
undi_rom rather than struct pxe_driver.  (This is part of the naming
consistency fixes).
 2007-01-08 02:38:10 +00:00
Michael Brown
675fe200e5 Use "struct undi_device" instead of "struct pxe_device", and use the 
function prefix "undinet_" and the variable name "undinic" in undinet.c,
so that we can reserve the variable name "undi" for a struct undi_device.

The idea is that we preserve the Etherboot 5.4 convention that the "UNDI"
code refers to our using an underlying UNDI stack, while the "PXE" code
refers to our providing a PXE API.
 2007-01-08 02:24:53 +00:00

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.

85a41b25fe Move START_UNDI, UNDI_STARTUP, UNDI_INITIALIZE and 
UNDI_GET_INFORMATION calls into drivers/net/undi.c.  undi_probe() now
gets given a pxe_device representing a PXE stack that has been loaded
into memory but not initialised in any way.

6cf488dcf7 Obsolete; net driver functionality is now in undi_net.c and bus driver 
functionality is now in pxebus.c.  (Not all bus functionality is ported
across yet.)
 2007-01-04 19:42:05 +00:00
Michael Brown
7e07dfb2f4 Added PXE bus driver (with support only for using PXE structures found

de2fc50f4c Add as a separate file so that we can do "make bin/xxxx.kpxe" rather than 
having to edit PXELOADER_KEEP_ALL as a config option.

350603cb86 Don't include __FUNCTION__ in assert() messages; it was causing the 
function name to appear within the objects even in non-asserting
builds.  (This could be considered a gcc bug.)

Removing __FUNCTION__ from assert() reduces the size of bin/blib.a by
around 2.5%!

Michael Brown
feb4f65d1e Use auto-colourisation for debug messages. 
Truncate TX length to TCP window at time of transmission rather than at
time of adding to TX packet; this is conceptually cleaner and also allows
the application to call tcp_send() multiple times to build up a single
packet.

ce9819af27 Redefine TCP state to include "flags that have been sent" rather than 
"flags that are currently being sent".  This allows at least one special
case (checking that we haven't already sent a FIN in tcp_rx_fin()) to be
collapsed.

6ceb55fad0 When login fails, leave the session open but not in full feature 
phase.  In iscsi_issue(), detect this state and immediately refuse the

cacd6b1d04 KEY_XXX constants are now defined in gpxe/keys.h. Kept separate from

43d976edd0 Prevent NULL from ever pointing to some real code or data. (This was 
causing the serial console to ignore input, because it happened to end up

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.

8bff0f0619 Avoid draining the keyboard buffer during gateA20_set(). It shouldn't 
technically be necessary, because the "enable A20" command requires
only that the keyboard controller is ready to accept input (i.e. that
its input buffer is empty), and shouldn't also require that the
keyboard is ready to send output (i.e. that its output buffer is also
empty).  See http://www.smsc.com/main/tools/io-bios/42i.pdf section
3.1 ("Command Invocation") for a justification.

gateA20_set() is called on every real-mode transition (in case some
idiot piece of external code such as Intel's PXE stack decided it
would be fun to re-disable A20), so draining the keyboard buffer means
that we end up losing keypresses on some systems.  In particular, this
makes typing at the command line almost impossible, and causes
Etherboot to ignore Ctrl-Alt-Del.

We should really implement a gateA20_test() function to verify that
gate A20 has been correctly enabled, and think about adding other
commonly-used methods such as Fast Gate A20.

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.

a3d508b648 Clarified packet ownership transfer between a few functions. 
Added a large number of missing calls to free_pkb().  In the case of UDP,
no received packets were ever freed, which lead to memory exhaustion
remarkably quickly once pxelinux started up.

In general, any function with _rx() in its name which accepts a pk_buff
*must* either call free_pkb() or pass the pkb to another _rx() function
(e.g. the next layer up the stack).  Since the UDP (and TCP) layers don't
pass packet buffers up to the higher-layer protocols (the
"applications"), they must free the packet buffer after calling the
application's newdata() method.
