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.

alloca() can be useful in some (limited) circumstances.

Michael Brown
6a03552381
Distinguish between ENOMEM (as representing a lack of internal memory
...
as allocated by malloc()) versus all other errors, in particular
ENOBUFS (representing a lack of external buffer space, e.g. in a
device's TX queue or a user buffer).
2007-01-11 16:30:21 +00:00

Use generic "struct image" rather than "struct elf".
2007-01-11 16:10:32 +00:00
Michael Brown
c6c63d954d
Rename "image" field to "data", because "image->image" is just confusing.

Move include/image.h to include/gpxe/image.h

Michael Brown
230f16538f
Create include/gpxe/elf.h for the ELF bits that aren't part of the ELF

7ad1c2eaa8
Removed the Etherboot-specific ELF-image code and replaced it with a

generic ELF loader, to be used by the multiboot code.
2007-01-11 14:44:03 +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
c980cdd0aa
Move memmap.h out of arch/i386; it no longer contains anything
...
architecture-dependent and is needed by the ELF code.
2007-01-11 14:08:44 +00:00
Michael Brown
fbfed96965
buffer.c should be using copy_{to,from}_user, rather than

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
c821a7b20d
Add udp_sendto_via() to allow e.g. DHCP to transmit without first having

2007-01-09 23:48:18 +00:00
Michael Brown
c65fae2475
Add RX quotas to the net device poll() method. This avoids the problem
...
of alloc_pkb() exhaustion when e.g. an iSCSI-booted DOS session is left
idle for a long time at the C:\ prompt and builds up a huge packet
backlog.
2007-01-09 21:47:01 +00:00
Michael Brown
18e5353bed
Rename pkb_available() to pkb_tailroom() for consistency with Linux's
...
skb_tailroom(). Add pkb_headroom().
2007-01-09 20:56:31 +00:00
Michael Brown
b7fcfe8ece
Added net device TX queue; this will be needed to support the PXE UNDI API
...
(which will need us to wait for TX completions).
Added debug autocolourisation to netdevice.c

0638945c7e
Add PXE driver-scanning code, capable of locating all PXE ROMs in a system
...
and matching them up to (e.g. PCI) devices.
2007-01-05 01:52:06 +00:00
Michael Brown
7e07dfb2f4
Added PXE bus driver (with support only for using PXE structures found
...
lying about in memory, not for loading from ROM), and UNDI net driver.
2007-01-04 19:38:34 +00:00
Michael Brown
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%!
2007-01-04 13:48:13 +00:00

Michael Brown
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.

Cannot immediately overwrite the peer address when we parse

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

curses.h so that you don't have to suffer the curses namespace pollution
just to get the symbolic key names.

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.

Michael Brown
7de5d32ff5
cmdlinelib.c now calls system() rather than doing its own tokenisation
...
(which was extremely heavy on calls to malloc()).
Moved include/command.h to include/gpxe/command.h, since it's
gPXE-specific.
2006-12-08 01:26:11 +00:00

Michael Brown
931f94dca3
Generalised the SPI abstraction layer to also be able to handle interfaces

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.

Remove unused attribute from __table macros; the tables are no longer

static since otherwise gcc4 optimises them away completely. Also, it

udp_connect() now follows the standard BSD sockets semantics and simply

Split DHCP packet creation into two parts: creating the basic packet
...
structure, and populating it with options. This should allow us to
use the same basic options list for both DHCPDISCOVER and DHCPREQUEST,

(e.g. requested IP address) in request packets.

Add sketch code to reassemble a DHCP packet from our internal "everything
...
is a DHCP option" data structures.
We need this code in order to be able to return a DHCP packet to a PXE NBP
which reflects options from our multiple sources (e.g. NVS and DHCP
server). This is expensive, but necessary. Having paid this cost, we may
as well try to use the same code to generate our DHCP request packets,
since the process is similar.
