Create include/gpxe/elf.h for the ELF bits that aren't part of the ELF
...
standard and so don't belong in include/elf.h
2007-01-11 15:25:07 +00:00

Update TFTP to use a struct buffer rather than a callback.
...
Add debug autocolourisation to TFTP.

Use physical address in debug messages; they make more sense to read.

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
10980c12ee
Add image directory back in
2007-01-11 14:43:15 +00:00
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
ceca6b185c
Added user_to_phys() and memset_user().
2007-01-11 14:27:27 +00:00
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
c6a4055fae
Add phys_to_user() and copy_user().
2007-01-11 14:01:20 +00:00
fbfed96965
buffer.c should be using copy_{to,from}_user, rather than
...
copy_{to,from}_phys.

I hate NULL pointer dereferences.

Use pkb_pad() rather than doing it the dangerous way :)
2007-01-11 05:26:16 +00:00
a3ed0cbbc7
Extract packet-padding login from rtl8139.c to a separate pkbpad.c file.

Change FTP to use a data buffer rather than a callback function.
2007-01-11 04:51:20 +00:00
c0ef730ec4
Fix bug in buffer.c, add buffer mini-unit test.
2007-01-11 04:46:41 +00:00
83fa318b86
Added strerror(0)=="No error", so that TCP protocols can use
...
strerror(rc) in their closed() methods without producing "Error
0x0000" when the connection is closed normally.
2007-01-11 04:01:31 +00:00
e2dcd05b67
Update buffer-handling code to enable expandable buffers.
2007-01-11 03:50:47 +00:00
bb2024c6d6
Move include/buffer.h to include/gpxe/buffer.h

Warn when net device on an active route is not open.
2007-01-10 20:58:36 +00:00
d45c5e7ce7
Add "route" command (which currently only displays the routing table; it
...
can't modify it).
2007-01-10 20:51:14 +00:00
d9ba8f790b
Add route() function to display routing table.
2007-01-10 20:38:20 +00:00

Try booting from the "boot" network device first (i.e. the one which we
...
were loaded from). The code to identify this device isn't present yet,
but the code to act upon the knowledge is.
2007-01-10 20:21:42 +00:00
1fa5cd0e2b
Add find_pci_netdev()
2007-01-10 16:16:05 +00:00
fdc97499bf
Add device description fields to struct device.
2007-01-10 15:27:48 +00:00
489a4004d7
Give UNDI device a more meaningful name.
2007-01-10 05:52:04 +00:00

Force ordering of commands within help list.
2007-01-10 05:13:20 +00:00

Force ordering of commands in help list.

Having forced __table() to natural structure alignment, it now seems
...
that we *can* place arrays in tables, which means we can force the
order within a table without having to resort to explicitly numbered
sections on everything.
2007-01-10 05:08:05 +00:00
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
cc9b32c405
Remove uIP; we haven't used it for quite some time now.
2007-01-10 02:52:58 +00:00
753e156844
Allow udp_{send,sendto,sendto_via} to be called outside of the
...
udp_senddata() callback. This will simplify any UDP protocols that don't
need the temporary buffer.
2007-01-10 02:46:39 +00:00
649b789e93
DHCP transmits via specified net device, so no need to create a dummy
...
routing table entry just to fool ipv4.c any more.
2007-01-10 02:37:23 +00:00
c821a7b20d
Add udp_sendto_via() to allow e.g. DHCP to transmit without first having
...
to set up dummy routing entries.
2007-01-10 02:31:38 +00:00
f008b77ba2
Allow an explicit network device to be specified for IP-layer
...
transmissions.
2007-01-10 02:25:11 +00:00
9869659895
Add interface management commands
2007-01-10 02:04:07 +00:00
55e590ab3a
Move header file for usr/autoboot.c to include/usr
2007-01-10 02:03:20 +00:00
d24b80acf2
Added network interface management commands
2007-01-10 01:55:07 +00:00
98b6154c3e
Add "name" field to network device, to facilitate netdev commands.
2007-01-09 23:48:18 +00:00
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
e822bc2a90
Autopadding was sometimes overwriting the struct list_head at the end
...
of the packet buffer. Although pkbuffs are guaranteed to be at least
PKB_ZLEN bytes long, there's no guarantee that the data starts at the
start of the packet buffer.
Since we have to align data for rtl8139 anyway, and since the start of
the packet buffer is guaranteed to be aligned to PKB_ALIGN, we may as
well just shuffle the packet down so that it starts at the start of
the packet buffer. This simultaneously aligns the packet and ensures
that there is enough room for the zero-padding.
2007-01-09 21:01:55 +00:00
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
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
2007-01-09 20:18:31 +00:00
8a268073a7
Move start/stop/expire debug messages to DBG2() level.
2007-01-09 17:39:52 +00:00
3c2cc59d25
Added ability to break ISR processing over several calls to poll().
...
This will allow us to implement RX quotas.
2007-01-09 17:04:10 +00:00
aa7bda7b47
Send EOI after enabling interrupt, in case the device had asserted IRQ
...
to the PIC while it was disabled.
2007-01-09 14:53:19 +00:00
a2ffe8c123
Allow boot sector to completely destroy real-mode stack, but still
...
manage to return control.
2007-01-09 14:13:59 +00:00
a9369bb503
Leave protected-mode return address on PM stack when issuing a
...
real_call(), rather than moving it to the RM stack and back again.
This allows the real-mode function to completely destroy the stack
contents, provided that it manages to return to real_call().
2007-01-09 14:13:06 +00:00
2eeb7c4fe7
Define "connected" as
...
"when SYN is ACKed and we have already received SYN", or
"when SYN is received and we have already had SYN ACKed"
rather than just
"when SYN is ACKed"
This avoids spuriously calling the connected() method when we receive
a RST,ACK in response to a SYN.
2007-01-09 05:01:22 +00:00
70cc3a164a
Reset character attributes before start of welcome banner, in case
...
it's a serial console and remembers state from the previous program
run.
