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).

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 f08093b0d9 Remove spurious debug message 2007-01-08 03:37:32 +00:00
Michael Brown f0edd11c7d Now split out into undirom.c and undiload.c 2007-01-08 03:35:51 +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 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 3b2f6e4585 Currently unusable; do not attempt to compile 2007-01-04 19:37:21 +00:00
Michael Brown 70acce06e4 This file is no longer used 2007-01-04 19:36:31 +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.
 2007-01-04 19:35:10 +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 20681d6168 Allow empty checksums on received packets 2007-01-04 05:17:28 +00:00
Michael Brown 290c5ee779 Don't automatically call gateA20_set() when returning from a real-mode 
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.
 2007-01-04 03:44:36 +00:00
Michael Brown 7fafa89258 A DHCP session holds a persistent reference to a network device 2007-01-04 03:42:28 +00:00

Michael Brown 35b5e5d3f5 Minirouting table entries hold a persistent reference to a net_device. 2007-01-04 03:10:21 +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 b0daa99dce Send RST packets when we get a non-matching connection, or receive an 
out-of-range ACK.

Michael Brown 285beeff7c Tidy up debug messages 
Move routing into a separate function
 2007-01-03 16:39:11 +00:00
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 61ed298bc7 Merge changes from mcb-tcp-fixes branch. 2006-12-27 23:09:46 +00:00
Michael Brown b6def29f2b Keep running the main processing loop while waiting for input. 2006-12-27 22:59:40 +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 9485478acc ibft_fill_data() prototype change. 2006-12-21 18:42:51 +00:00
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.

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 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 a6d1815bc6 Obsolete for some time now. 2006-12-20 07:05:32 +00:00
Michael Brown 84202d89f0 Split the (quick hack) boot logic out from main.c to autoboot.c, add a

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

 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

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 
calls.  This does make a visible difference when clearing the screen with
werase() inside bochs or qemu.
 2006-12-19 01:15:05 +00:00
Michael Brown e85bf52446 Avoid cursor move on every single character 2006-12-19 00:51:32 +00:00
Michael Brown 8e460de6be Obsolete, and no longer functions 2006-12-19 00:34:54 +00:00

the (slow) werase().
 2006-12-19 00:33:36 +00:00

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

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
