Call hide_etherboot() from startup(), rather than requiring the prefix to

do it.

Make shutdown functions callable by OS image's exec methods.

Some operating systems get a nasty shock if a region of the E820 map seems
...
to start on a non-page boundary. Make life safer by rounding out our
edited regions.

Damn it; my lovely resilient scheme falls down when you have a protocol
...
that switches from line-oriented to byte-oriented partway through, such as
HTTP.

No need to maintain a received byte count; we always fill in sequential
...
order so we can just use buffer->fill.
2007-01-12 17:16:46 +00:00
Michael Brown
996b091b50
Added generic line-buffering code (a la stdio)

Let ifmgmt.c take care of calling efree(), since it's the once which
...
took out the contract to eventually call efree() when it called fetch().
Maintain the most recently loaded image at the start of the list, so that
imgautoselect() will pick it.

Rearrange struct image to reflect usage of the fields

API change: the raw image will no longer be (hypothetically) discarded

after a call to load().

Force probing of multiboot before ELF.

Michael Brown

fetch() now knows nothing about struct image; it simply loads a file and
...
returns the allocated buffer.
2007-01-12 08:02:27 +00:00

Add free_image

Add UNULL

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.
2007-01-11 23:43:29 +00:00

Use generic "struct image" rather than "struct elf".
2007-01-11 16:10:32 +00:00
Michael Brown

Rename "image" field to "data", because "image->image" is just confusing.

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

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

buffer.c should be using copy_{to,from}_user, rather than

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

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

Rename pkb_available() to pkb_tailroom() for consistency with Linux's
