Michael Brown 2c66588f3e Add UNULL 2007-01-12 01:40:12 +00:00
Michael Brown 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.

Michael Brown 79a399c05a alloca() can be useful in some (limited) circumstances. 2007-01-11 23:19:31 +00:00
Michael Brown c468c68661 Add command line that can be passed to executed images. 2007-01-11 21:19:29 +00:00
Michael Brown 819cd3f41c Limit -ENOEXEC to mean "this is not in my format". 2007-01-11 17:06:25 +00:00
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).

Michael Brown c810baad37 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. 2007-01-11 16:07:30 +00:00
Michael Brown 4fc9333159 Move include/image.h to include/gpxe/image.h 2007-01-11 16:04:36 +00:00
Michael Brown 230f16538f 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
Michael Brown 0010e10ef3 Update TFTP to use a struct buffer rather than a callback.
Add debug autocolourisation to TFTP.
2007-01-11 15:14:54 +00:00
Michael Brown 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
copy_{to,from}_phys.
2007-01-11 05:42:06 +00:00
Michael Brown a3ed0cbbc7 Extract packet-padding login from rtl8139.c to a separate pkbpad.c file. 2007-01-11 05:25:50 +00:00
Michael Brown 6918cf9e9e Change FTP to use a data buffer rather than a callback function. 2007-01-11 04:51:20 +00:00
Michael Brown e2dcd05b67 Update buffer-handling code to enable expandable buffers. 2007-01-11 03:50:47 +00:00
Michael Brown bb2024c6d6 Move include/buffer.h to include/gpxe/buffer.h 2007-01-11 01:47:26 +00:00
Michael Brown d9ba8f790b Add route() function to display routing table. 2007-01-10 20:38:20 +00:00
Michael Brown 1fa5cd0e2b Add find_pci_netdev() 2007-01-10 16:16:05 +00:00
Michael Brown fdc97499bf Add device description fields to struct device. 2007-01-10 15:27:48 +00:00
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
to set up dummy routing entries.
2007-01-10 02:31:38 +00:00
Michael Brown f008b77ba2 Allow an explicit network device to be specified for IP-layer
transmissions.
2007-01-10 02:25:11 +00:00
Michael Brown 55e590ab3a Move header file for usr/autoboot.c to include/usr 2007-01-10 02:03:20 +00:00
Michael Brown d24b80acf2 Added network interface management commands 2007-01-10 01:55:07 +00:00
Michael Brown 98b6154c3e Add "name" field to network device, to facilitate netdev commands. 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
2007-01-09 20:18:31 +00:00
Michael Brown 76525294ee Clean up connection closing and permanent failure logic. 2007-01-09 04:31:33 +00:00
Michael Brown 79c5f0ba04 Added PCI_BASE_CLASS() macro 2007-01-08 03:32:41 +00:00
Michael Brown 5af4918356 Added support for wildcard device/vendor ID matches 2007-01-08 03:23:38 +00:00
Michael Brown 20c9fc407e Remove types and prototypes now provided in the undi*.h headers. 2007-01-08 03:05:34 +00:00
Michael Brown 9780fef360 Partial implementation of UNDI loader caller. 2007-01-05 03:24:39 +00:00
Michael Brown 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 0c03bb5a9a Make open() and close() an official part of the netdevice API.
Call netdevice's poll() and transmit() methods only when device is open.

Michael Brown 7fafa89258 A DHCP session holds a persistent reference to a network device 2007-01-04 03:42:28 +00:00
Michael Brown ac53da1790 Added missing #include 2007-01-04 03:40:07 +00:00
Michael Brown b29861a5aa IPv6 minirouting table entries hold persistent references to net devices. 2007-01-04 03:28:30 +00:00
Michael Brown b22d4405c0 An AoE session holds a persistent reference to a net device. 2007-01-04 03:21:45 +00:00
Michael Brown bdf79ec8dc Use hotplug support to notify persistent reference holders when a
net_device is unregistered.
2007-01-04 03:09:28 +00:00
Michael Brown 0063725d28 Minimal hotplug support: provide a facility for notifying persistent
reference holders that their reference is about to become invalid.
2007-01-04 03:08:16 +00:00
Michael Brown a0525a4ed3 Verify checksums on the RX datapath.
Simplify checksum generation on the TX datapath.
2007-01-03 20:48:52 +00:00
Michael Brown b91b9d3d88 Use whole bytes for the ACKED and RCVD portions of tcp_state; it
produces slightly smaller code.
2006-12-30 01:32:22 +00:00
Michael Brown 2494625702 Added auto-colourising DBGC() macro 2006-12-29 03:05:21 +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.
