Michael Brown e2c0055e23 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.
2007-01-12 09:46:10 +00:00

2007-01-12 08:56:48 +00:00
Michael Brown 48e0fc3447 API change: the raw image will no longer be (hypothetically) discarded
after a call to load().

Michael Brown 475d6d1f7c 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
Michael Brown 2876197306 Allow "imgexec" with no arguments to boot the file that was loaded with

2007-01-12 03:14:15 +00:00
Michael Brown 859da6bd32 Allow external code to update hidden memory regions. 2007-01-12 03:13:04 +00:00
Michael Brown 687c1e3227 Nothing (not even hidemem.c) uses this file! 2007-01-12 02:45:46 +00:00

Michael Brown 6c894c2a2e Fix typo 2007-01-12 01:37:38 +00:00
Michael Brown e4c6418ac0 We may be required to page-align modules, so let's make sure we catch
it if we don't.
2007-01-12 00:09:16 +00:00
Michael Brown 7bf94b5ad6 Allow for named images. 2007-01-11 23:45:18 +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.
2007-01-11 23:43:29 +00:00
Michael Brown 79a399c05a alloca() can be useful in some (limited) circumstances. 2007-01-11 23:19:31 +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).
2007-01-11 16:30:21 +00:00
Michael Brown 143e3b84a4 Downloaded from current grub CVS. 2007-01-11 16:22:03 +00:00
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 d84ec0e5d5 Had this file lying around for ages; may as well check it in. 2007-01-11 15:31:50 +00:00
Michael Brown 91ac92bc86 Try image as ELF file first. (Don't yet actually try to execute it). 2007-01-11 15:27:06 +00:00
Michael Brown 3460860bef Print informative error message when boot fails. 2007-01-11 15:26:17 +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 d9204ef676 Use physical address in debug messages; they make more sense to read. 2007-01-11 15:08:58 +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 10980c12ee Add image directory back in 2007-01-11 14:43:15 +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 ceca6b185c Added user_to_phys() and memset_user(). 2007-01-11 14:27:27 +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 c6a4055fae Add phys_to_user() and copy_user(). 2007-01-11 14:01:20 +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 037da9d840 I hate NULL pointer dereferences. 2007-01-11 05:27:02 +00:00
Michael Brown 03390f0cd6 Use pkb_pad() rather than doing it the dangerous way :) 2007-01-11 05:26:16 +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 c0ef730ec4 Fix bug in buffer.c, add buffer mini-unit test. 2007-01-11 04:46:41 +00:00
Michael Brown 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
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 de042993c0 Warn when net device on an active route is not open. 2007-01-10 20:58:36 +00:00
Michael Brown d45c5e7ce7 Add "route" command (which currently only displays the routing table; it
can't modify it).
2007-01-10 20:51:14 +00:00
Michael Brown d9ba8f790b Add route() function to display routing table. 2007-01-10 20:38:20 +00:00
Michael Brown 78ded6604a 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
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 489a4004d7 Give UNDI device a more meaningful name. 2007-01-10 05:52:04 +00:00
Michael Brown f396f1f9d3 Force ordering of commands within help list. 2007-01-10 05:13:20 +00:00
Michael Brown cef551376f Force ordering of commands in help list. 2007-01-10 05:10:30 +00:00
Michael Brown 77bb7b13a7 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
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 cc9b32c405 Remove uIP; we haven't used it for quite some time now. 2007-01-10 02:52:58 +00:00
Michael Brown 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
Michael Brown 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
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 9869659895 Add interface management commands 2007-01-10 02:04:07 +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 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
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 8a268073a7 Move start/stop/expire debug messages to DBG2() level. 2007-01-09 17:39:52 +00:00
