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 dc51af59a4 Capable of starting a multiboot kernel (albeit without the multiboot 
information table yet).
 2007-01-11 18:41:15 +00:00
Michael Brown 9196e9069c Add PHYS_CODE, for use as in __asm__ ( PHYS_CODE ( ... ) ), comparable 
to the REAL_CODE interface.
 2007-01-11 18:40:46 +00:00
Michael Brown d488a172eb Capable of loading a multiboot image into memory 2007-01-11 17:44:42 +00:00
Michael Brown 7cf4a72389 Add placeholder elf_execute() 2007-01-11 17:44:07 +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
Michael Brown 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
Michael Brown 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
Michael Brown a2ffe8c123 Allow boot sector to completely destroy real-mode stack, but still 
manage to return control.
 2007-01-09 14:13:59 +00:00
Michael Brown 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
Michael Brown 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
Michael Brown 70cc3a164a Reset character attributes before start of welcome banner, in case 
it's a serial console and remembers state from the previous program
run.
 2007-01-09 04:51:27 +00:00
Michael Brown aaca21a2b6 We can't assert that the RX engine is idle in iscsi_done(), because it 
may be called during the RX data processor, before the RX engine
transitions back to idle.  It doesn't really matter if the RX engine
isn't idle when iscsi_done() is called, because it will just pick up
where it left off on the next call.  (The same is not true for the TX
engine, so keep the TX engine assertion.)
 2007-01-09 04:42:23 +00:00
Michael Brown 6ea07b9247 Use debug auto-colourisation. 2007-01-09 04:38:39 +00:00
Michael Brown 76525294ee Clean up connection closing and permanent failure logic. 2007-01-09 04:31:33 +00:00
Michael Brown 2738bdf74b Obsoleted by drivers/net/undionly.c 2007-01-09 03:22:11 +00:00
Michael Brown d606edb41d Added UNDI root bus driver (which saves including all the PCI bus code, 
UNDI ROM code etc. when you just want a "undi.kpxe"-type image).

This driver cannot be used in conjunction with any other driver (it will
crash), or in any other format than .kpxe (it just won't find any network
devices).
 2007-01-09 03:20:22 +00:00
Michael Brown 159930862f Added missing call to undinet_remove() 2007-01-09 03:08:01 +00:00
Michael Brown 6b09dd8244 undipci_probe() has to calculate busdevfn anyway, so we may as well pass 
it directly to undi_load_pci().
 2007-01-09 02:58:07 +00:00
Michael Brown ed44e3730d Avoid erasing non-existent signatures in undi_unload() 2007-01-09 02:53:24 +00:00
Michael Brown a2be828a33 Avoid leaving preloaded_undi with invalid PXENV+/!PXE structure 
addresses if the signature checks fail.
 2007-01-09 02:52:28 +00:00
Michael Brown 697bcc9d24 Since we now always unload the base code stack (even if we keep UNDI), 
we can never return to the PXE stack and must always use INT 18.
 2007-01-09 02:46:58 +00:00
Michael Brown f2f492a536 If preloaded device matches, use that rather than going via the UNDI 
loader.
 2007-01-09 02:32:06 +00:00
Michael Brown 2436dac281 Populate preloaded_undi device when applicable. 2007-01-09 02:29:54 +00:00
Michael Brown 937289cdc8 Provide storage for an undi_device structure representing the preloaded 
UNDI stack.
 2007-01-09 02:29:18 +00:00
Michael Brown 47222d5ed8 Call PXENV_UNDI_GET_NIC_TYPE to identify NIC physical device. 
Record all information required for populating a struct undi_device.

Make debugging output more human-readable.
 2007-01-09 01:42:28 +00:00
Michael Brown cea2221737 Use fixed-width fields in struct undi_device, so that pxeprefix.S will be 
able to populate the structure.
 2007-01-09 01:41:26 +00:00
Michael Brown fbdebac5f4 Copy pxelinux's shutdown sequence: use UNLOAD_STACK without STOP_BASE, 
and call UNDI_SHUTDOWN first to make sure the NIC is in a safe state.
 2007-01-08 05:06:26 +00:00
Michael Brown 8f8af10b22 New strategy: always stop both base code and UNDI. Always free base code 
memory (unless we get an error while stopping the base code).  Leave UNDI
resident (though stopped) for .kpxe.

Still need to add code to record the device identification parameters
prior to stopping UNDI.
 2007-01-08 03:48:26 +00:00
Michael Brown 075d79f6d4 Checking in obsolete but working memory-scanning code just for the record 2007-01-08 03:45:00 +00:00
Michael Brown 67e824b539 Neaten up debug messages 2007-01-08 03:42:19 +00:00
Michael Brown f08093b0d9 Remove spurious debug message 2007-01-08 03:37:32 +00:00

Michael Brown 07e5d4e3dc Added any-PCI-device UNDI driver 2007-01-08 03:34:47 +00:00
Michael Brown 66f7bcc785 Tidied up debug messages 2007-01-08 03:34:06 +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 a6ba48e51e Added debugging statements 2007-01-08 03:04:54 +00:00
Michael Brown 239965ff3b Added missing includes 2007-01-08 03:03:42 +00:00
Michael Brown 6115356859 Added missing declarations 2007-01-08 02:51:27 +00:00
Michael Brown aff96c13d2 Added missing include 2007-01-08 02:51:04 +00:00
Michael Brown afc01a1a7f Split UNDI load/unload out into undiload.c. 2007-01-08 02:48:17 +00:00
Michael Brown 359c888aec Remove obsolete includes 2007-01-08 02:39:56 +00:00
Michael Brown 6fc75f659b Separated out UNDI ROM location code into undirom.c, and use struct 
undi_rom rather than struct pxe_driver.  (This is part of the naming
consistency fixes).
 2007-01-08 02:38:10 +00:00
Michael Brown 675fe200e5 Use "struct undi_device" instead of "struct pxe_device", and use the 
function prefix "undinet_" and the variable name "undinic" in undinet.c,
so that we can reserve the variable name "undi" for a struct undi_device.

The idea is that we preserve the Etherboot 5.4 convention that the "UNDI"
code refers to our using an underlying UNDI stack, while the "PXE" code
refers to our providing a PXE API.
 2007-01-08 02:24:53 +00:00
Michael Brown 36c1e1aa57 Renamed undi.c to undinet.c. (undi.c will become the UNDI PCI driver) 2007-01-08 02:02:07 +00:00
Michael Brown 234d81728a Obsolete 2007-01-08 02:00:55 +00:00
Michael Brown 7b9617f5df Add device to hierarchy before calling the driver's probe() function; this 
way everything remains consistent if the probe() ends up creating child
devices.
 2007-01-08 01:29:51 +00:00
Michael Brown d3558fdd3a Remove accidentally checked-in code 2007-01-07 19:05:28 +00:00
Michael Brown 85a41b25fe Move START_UNDI, UNDI_STARTUP, UNDI_INITIALIZE and 
UNDI_GET_INFORMATION calls into drivers/net/undi.c.  undi_probe() now
gets given a pxe_device representing a PXE stack that has been loaded
into memory but not initialised in any way.
 2007-01-07 19:02:17 +00:00
Michael Brown 23cb837951 Remember to enable/disable the interrupt at the PIC. 
Handle failures in undi_open() properly.
 2007-01-07 13:31:39 +00:00
Michael Brown 9ab5c0dde7 Remove redundant debug message 2007-01-05 16:15:50 +00:00
Michael Brown fa9055197d UNDI loader routine now works 2007-01-05 16:11:05 +00:00
Michael Brown 477a70697a Added PnP BIOS scanning code, separated out from the UNDI driver 2007-01-05 16:10:03 +00:00
Marty Connor 7dee2556f4 Fixed typo 2007-01-05 16:09:47 +00:00
Michael Brown d0a3cc3417 Avoid creating implicit memcpy()s 2007-01-05 14:48:20 +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 ef50ea0b2b Renamed undi_net.c to undi.c. 2007-01-04 19:43:35 +00:00
Michael Brown 6cf488dcf7 Obsolete; net driver functionality is now in undi_net.c and bus driver 
functionality is now in pxebus.c.  (Not all bus functionality is ported
across yet.)
 2007-01-04 19:42:05 +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 e28db95de6 Obsolete 2007-01-04 19:37:31 +00:00

Michael Brown b12cd68726 Ripped out everything except the ability to send EOI to the PIC. 2007-01-04 19:36:18 +00:00
Michael Brown de2fc50f4c Add as a separate file so that we can do "make bin/xxxx.kpxe" rather than 
having to edit PXELOADER_KEEP_ALL as a config option.

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%!

call.
 2007-01-04 04:32:18 +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.
 2007-01-04 04:20:08 +00:00
Michael Brown d4894f0127 We *should* use the persistent reference API for our netdev reference, 
but there's so much else missing that it's not worth doing right now.

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.

Michael Brown 718294553b Fix compiler warning 2007-01-03 15:56:15 +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 83e1340d88 Use autocolourisation 2006-12-29 14:09:23 +00:00
Michael Brown feb4f65d1e Use auto-colourisation for debug messages. 
Truncate TX length to TCP window at time of transmission rather than at
time of adding to TX packet; this is conceptually cleaner and also allows
the application to call tcp_send() multiple times to build up a single
packet.
 2006-12-29 14:03:03 +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.
 2006-12-29 00:44:31 +00:00
Michael Brown be31970e36 Don't send a second FIN if we receive a FIN while in FIN_WAIT_2 2006-12-27 23:44:05 +00:00

Michael Brown 1a11cc5c5b Added times to start/stop log messages 2006-12-27 22:56:39 +00:00
Michael Brown 4cc1c1bd4c Ensure that old TCP connection state is destroyed before attempting to 
reopen connection.  (The TCP API will soon change to render this step
unnecessary.)
 2006-12-22 13:04:50 +00:00
Michael Brown a2e3357825 Cannot immediately overwrite the peer address when we parse 
TargetAddress from the login response, because we still need the old
address while we close the connection!

Michael Brown d6f9152bfa Avoid null pointer dereferences when no username/password specified. 2006-12-21 18:38:24 +00:00
Michael Brown 6ceb55fad0 When login fails, leave the session open but not in full feature 
phase.  In iscsi_issue(), detect this state and immediately refuse the
operation.  This avoids trying multiple logins when scsi.c tries
several times to read the drive capacity.
 2006-12-21 17:43:43 +00:00
Michael Brown 024809d454 Use a bigger buffer for the initiator IQN 2006-12-21 17:42:02 +00:00

Michael Brown f58f193633 Engage brain: since when was zero >= 0x80 ? 2006-12-21 05:15:26 +00:00
Michael Brown 9c3b4e5b0b Some BIOSes return 0xe0 for extended characters. Just assume that 
anything over 0x80 is an extended character.
 2006-12-21 00:07:48 +00:00
Michael Brown 839d425c6e Added missing header 2006-12-20 23:43:44 +00:00
Michael Brown dbb7b30cca Return ANSI sequences for special keys 2006-12-20 23:42:28 +00:00
Michael Brown f33a03c1e5 Use getkey() and symbolic key names. 2006-12-20 22:25:54 +00:00
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.
 2006-12-20 22:24:45 +00:00
Michael Brown 4b2b8b02ab Use symbolic key names, and avoid moving beyond end of string 2006-12-20 22:21:09 +00:00

Michael Brown b9f8599537 Define KEY_MIN and use it in kb.c. 2006-12-20 21:10:32 +00:00
Michael Brown 43d976edd0 Prevent NULL from ever pointing to some real code or data. (This was 
causing the serial console to ignore input, because it happened to end up
linked with serial_ischar() at address 0, which core/console.c decided was
invalid).
 2006-12-20 20:28:20 +00:00
Michael Brown 6ceaa158da Return -EIO when verification fails, instead of -EINVAL. 2006-12-20 14:11:50 +00:00
Michael Brown cbeec25662 settings_ui() now returns a status code. 2006-12-20 11:42:48 +00:00

Michael Brown 84202d89f0 Split the (quick hack) boot logic out from main.c to autoboot.c, add a 
"boot" command to attempt booting from within the command shell, fall back
to shell if boot fails for any reason.
 2006-12-20 07:04:08 +00:00
Michael Brown 9ab17484d0 Explicitly call erase(), to cope with platforms where the ANSI clear 
screen sequence doesn't work (like bios_console.c on some platforms).
 2006-12-20 06:12:04 +00:00

the option config UI.
 2006-12-20 04:58:26 +00:00
Michael Brown 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.
 2006-12-20 04:20:13 +00:00
Michael Brown fc7dcc201b Added messages for some of the most common errors 2006-12-20 03:54:20 +00:00

Michael Brown 4f506328ad Use -ENOSPC rather than -ENOMEM, to distinguish the cases "generic out of 
memory" and "no space left for DHCP options"

command is linked in.
 2006-12-19 16:27:15 +00:00

Michael Brown cdfe61662b Assume a 24-line screen, since we can't (easily) avoid scrolling after 
printing in the bottom-right position.
 2006-12-19 01:16:43 +00:00
Michael Brown 0aa1223264 Optimise bios_putchar for speed(!) by avoiding two separate real-mode

the (slow) werase().

Michael Brown 426e847c4c Rename core.c->mucurses.c; bin/core.o is too generic to belong to mucurses. 2006-12-18 16:50:02 +00:00
Michael Brown 688eb60df4 Use int rather than short for bool; it will give more efficient code. 2006-12-18 16:48:09 +00:00
Michael Brown 2ed2b2efe8 Use iskey() and getchar() to interact with console, rather than object 
abstraction.
 2006-12-18 16:46:25 +00:00

Michael Brown 530bbf7cca Print welcome banner in bold (which will come out as bright white text 
on the BIOS console, or genuine bold font on a xterm "serial" console),
just to prove the concept of the ANSI escape sequence handling.
 2006-12-18 01:31:33 +00:00
Michael Brown 8b3a4c9862 Add basic ANSI escape sequence support to BIOS console 2006-12-18 01:19:38 +00:00

Michael Brown 9aa3e10d7c Use root-path option (as per RFC 4173) rather than filename option to 
determine iSCSI boot parameters.
 2006-12-08 15:53:49 +00:00
Michael Brown a1af111a87 Also request root-path. 2006-12-08 15:49:46 +00:00

Michael Brown cc697eeb1f Added "exit" back in as a standardised command. 2006-12-08 01:40:06 +00:00
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.

Michael Brown 2863d1a1de inet_aton() has a non-traditional return value 2006-12-06 20:44:29 +00:00
Michael Brown 38ae94f8ce A cleaner method of handling login redirection; just use the existing 
reconnection mechanism.  This avoids the problems of trying to reuse
the TCP connection structure before the old connection has cleanly exited.

Michael Brown cc0b92652f Call closed() method only when the connection is genuinely in the 
TCP_CLOSED state (i.e. after the final FIN/ACK exchange), and has been
removed from the list of TCP connections.

Michael Brown 89bcb57201 Update ftp.c to work with Nikhil's TCP stack. 
Remove the now-totally-obsolete sockaddr_in field from tcp.h.

Michael Brown a128b33b8b The VPD engine is broken and can't actually handle placing VPD 
anywhere other than offset 0 within the EEPROM, so we have to put our
settings at 0x100 instead.

Michael Brown 4c3e0fede5 Adjust EEPROM/flash detection to fit expected manufacturing practice. 2006-12-05 16:00:06 +00:00
Michael Brown 6a91a03409 Added options listed in 
http://www.microsoft.com/whdc/winlogo/hwrequirements.mspx as required
for iSCSI boot.  Note that options 204-206 are listed in the document
but don't seem to be defined anywhere on the web.

Michael Brown c6060a8fea Tidy up some more output. The command-line code needs some severe 
overhauling, but this is not the time to do it.
 2006-12-05 10:27:16 +00:00
Michael Brown e852f8e504 Slightly tidied up console messages. 2006-12-05 10:14:58 +00:00

Michael Brown 8bff0f0619 Avoid draining the keyboard buffer during gateA20_set(). It shouldn't 
technically be necessary, because the "enable A20" command requires
only that the keyboard controller is ready to accept input (i.e. that
its input buffer is empty), and shouldn't also require that the
keyboard is ready to send output (i.e. that its output buffer is also
empty).  See http://www.smsc.com/main/tools/io-bios/42i.pdf section
3.1 ("Command Invocation") for a justification.

gateA20_set() is called on every real-mode transition (in case some
idiot piece of external code such as Intel's PXE stack decided it
would be fun to re-disable A20), so draining the keyboard buffer means
that we end up losing keypresses on some systems.  In particular, this
makes typing at the command line almost impossible, and causes
Etherboot to ignore Ctrl-Alt-Del.

We should really implement a gateA20_test() function to verify that
gate A20 has been correctly enabled, and think about adding other
commonly-used methods such as Fast Gate A20.
