Michael Brown 3a505dfc35 [netdevice] Change link-layer push() and pull() methods to take raw types 
EFI requires us to be able to specify the source address for
individual transmitted packets, and to be able to extract the
destination address on received packets.

Take advantage of this to rationalise the push() and pull() methods so
that push() takes a (dest,source,proto) tuple and pull() returns a
(dest,source,proto) tuple.

Michael Brown 6b9cc25556 [netdevice] Split multicast hashing out into an mc_hash method 
Multicast hashing is an ugly overlap between network and link layers.
EFI requires us to provide access to this functionality, so move it
out of ipv4.c and expose it as a method of the link layer.

Michael Brown 832668105e [netdevice] Add maximum packet length as a net device property

Michael Brown 81d92c6d34 [efi] Add EFI image format and basic runtime environment 
We have EFI APIs for CPU I/O, PCI I/O, timers, console I/O, user
access and user memory allocation.

EFI executables are created using the vanilla GNU toolchain, with the
EXE header handcrafted in assembly and relocations generated by a
custom efilink utility.

Michael Brown 6554b79ff9 [uaccess] Formalise the uaccess API 
The userptr_t is now the fundamental type that gets used for conversions.
For example, virt_to_phys() is implemented in terms of virt_to_user() and
user_to_phys().

Michael Brown 16f1e35775 [timer] Formalise the timer API 
We now have two implementations for the timer API: one using the
time-of-day counter at 40:70 and one using RDTSC.  Both make use of
timer2_udelay().

Michael Brown f945d6d201 [retry] Use a separate flag to indicate that a retry timer is running 
Using start==0 to indicate a stopped timer is dangerous, because 0 is a
valid value for the current tick counter.

Michael Brown 2e812235f4 [makefile] Add -Wformat-nonliteral as an extra warning category 
-Wformat-nonliteral is not enabled by -Wall and needs to be explicitly
 specified.

Modified the few files that use nonliteral format strings to work with
this new setting in place.

Inspired by a patch from Carl Karsten <carl@personnelware.com> and an
identical patch from Rorschach <r0rschach@lavabit.com>.

Michael Brown ac663cf509 [efi] Add EFI headers from the EFI Development Kit (edk2) 
The intention is to include near-verbatim copies of the EFI headers
required by gPXE.  This is achieved using the import.pl script in
src/include/gpxe/efi.

Note that import.pl will modify any #include lines in each imported
header to reflect its new location within the gPXE tree.  It will also
tidy up the file by removing carriage return characters and trailing
whitespace.

Michael Brown 160b950af8 [libc] Define wchar_t in a gcc-compatible way

Michael Brown 9dccbc0af2 [i2c] Generalise i2c bit-bashing support to addressless devices 
Some devices (e.g. the Atmel AT24C11) have no concept of a device
address; they respond to every device address and use this value as
the word address.  Some other devices use part of the device address
field to extend the word address field.

Generalise the i2c bit-bashing support to handle this by defining the
device address length and word address length as properties of an i2c
device.  The word address is assumed to overflow into the device
address field if the address used exceeds the width of the word
address field.

Also add a bus reset mechanism.  i2c chips don't usually have a reset
line, so rebooting the host will not clear any bizarre state that the
chip may be in.  We reset the bus by clocking SCL until we see SDA
high, at which point we know we can generate a start condition and
have it seen by all devices.  We then generate a stop condition to
leave the bus in a known state prior to use.

Finally, add some extra debugging messages to i2c_bit.c.

Michael Brown afe1323c76 [compiler] Allow for selective disabling of debug levels at runtime 
The usefulness of DBGLVL_IO is limited by the fact that many cards
require large numbers of uninteresting I/O reads/writes at device
probe time, typically when driving a bit-bashing I2C/SPI bus to read
the MAC address.

This patch adds the DBG_DISABLE() and DBG_ENABLE() macros, which can
be used to temporarily disable and re-enable selected debug levels.
Note that debug levels must still be enabled in the build in order to
function at all: you can't use DBG_ENABLE(DBGLVL_IO) in an object
built with DEBUG=object:1 and expect it to do anything.

Michael Brown 30fb3b3810 [undi] Fill in ProtType correctly in PXENV_UNDI_ISR 
Determine the network-layer packet type and fill it in for UNDI
clients.  This is required by some NBPs such as emBoot's winBoot/i.

This change requires refactoring the link-layer portions of the
gPXE netdevice API, so that it becomes possible to strip the
link-layer header without passing the packet up the network stack.

Michael Brown 320b072c7a [pcbios] Support arbitrary splits of the e820 memory map 
Allow for an arbitrary number of splits of the system memory map via
INT 15,e820.

Features of the new map-mangling algorithm include:

  Supports random access to e820 map entries.

  Requires only sequential access support from the underlying e820
  map, even if our caller uses random access.

  Empty regions will always be stripped.

  Always terminates with %ebx=0, even if the underlying map terminates
  with CF=1.

  Allows for an arbitrary number of hidden regions, with underlying
  regions split into as many subregions as necessary.

Total size increase to achieve this is 193 bytes.

Andrew Schran ff2b6a512d [retry] Added configurable timeouts to retry timer 
New min_timeout and max_timeout fields in struct retry_timer allow
users of this timer to set their own desired minimum and maximum
timeouts, without being constrained to a single global minimum and
maximum. Users of the timer can still elect to use the default global
values by leaving the min_timeout and max_timeout fields as 0.

Michael Brown 481a21798d [autoboot] Retain initial-slash (if present) when constructing TFTP URIs 
When we boot from a DHCP-supplied filename, we previously relied on
the fact that the current working URI is set to tftp://[next-server]/
in order to resolve the filename into a full tftp:// URI.  However,
this process will eliminate the distinction between filenames with and
without initial slashes:

 cwuri="tftp://10.0.0.1/" filename="vmlinuz"  => URI="tftp://10.0.0.1/vmlinuz"
 cwuri="tftp://10.0.0.1/" filename="/vmlinuz" => URI="tftp://10.0.0.1/vmlinuz"

This distinction is important for some TFTP servers.  We now
explicitly construct a string of the form

 "tftp://[next-server]/filename"

so that a filename with an initial slash will result in a URI
containing a double-slash, e.g.

 "tftp://10.0.0.1//vmlinuz"

The TFTP code always strips a single initial slash, and so ends up
presenting the correct path to the server.

URIs entered explicitly by users at the command line must include a
double slash if they want an initial slash presented to the TFTP
server:

  "kernel tftp://10.0.0.1/vmlinuz"  => filename="vmlinuz"
  "kernel tftp://10.0.0.1//vmlinuz" => filename="/vmlinuz"

Andrew Schran 6b58992318 [tg3] Added support for tg3-5754. 
In tg3_chip_reset(), the PCI_EXPRESS change is taken from the Linux
tg3 driver. I am not sure what exactly it does (it is not documented
in the Linux driver), but it is necessary for the NIC to work
correctly.

Michael Brown 03c80c12b8 [iSCSI] Support Windows Server 2008 direct iSCSI installation 
Add yet another ugly hack to iscsiboot.c, this time to allow the user to
inhibit the shutdown/removal of the iSCSI INT13 device (and the network
devices, since they are required for the iSCSI device to function).

On the plus side, the fact that shutdown() now takes flags to
differentiate between shutdown-for-exit and shutdown-for-boot means that
another ugly hack (to allow returning via the PXE stack on BIOSes that
have broken INT 18 calls) will be easier.

I feel dirty.

Michael Brown dbe9269f3a [bzimage] Kill off the initrd image type 
We can just treat all non-kernel images as initrds, which matches our
behaviour for multiboot kernels.  This allows us to eliminate initrd as
an image type, and treat the "initrd" command as just another synonym for
"imgfetch".

Stefan Hajnoczi 6e670b5f38 [GDB] Remote debugging over UDP 
This commit implements GDB over UDP.  Using UDP is more complex than
serial and has required some restructuring.

The GDB stub is now built using one or both of GDBSERIAL and GDBUDP
config.h options.

To enter the debugger, execute the gPXE shell command:
gdbstub <transport> [<options>...]

Where <transport> is "serial" or "udp".  For "udp", the name of a
configured network device is required:
gdbstub udp net0

The GDB stub listens on UDP port 43770 by default.

Michael Brown 0d91c37ce5 [legacy] Align legacy drivers' __shared data to the maximum possible 
Some drivers that still use the legacy-driver wrapper (tg3 in particular)
apparently do not specify their alignment constraints properly.  This
hack forces any __shared data to be maximally aligned.

Note that this provides only 16-byte alignment; it is not possible to
request alignment to any greater than 16 bytes using
__attribute__((aligned)), since the relocation code will preserve only 16
byte alignment (and operation under -DKEEP_IT_REAL cannot preserve more
that 16 byte alignment).

Michael Brown aa160211c2 [udp] Verify local socket address (if specified) for UDP sockets 
UDP sockets can be used for multicast, at which point it becomes
plausible that we could receive packets that aren't destined for us
but that still match on a port number.

Michael Brown 77a5cc6b13 [ELF] Add ability to boot ELF images generated by wraplinux and mkelfImage 
Delete ELF as a generic image type.  The method for invoking an
ELF-based image (as well as any tables that must be set up to allow it
to boot) will always depend on the specific architecture.  core/elf.c
now only provides the elf_load() function, to avoid duplicating
functionality between ELF-based image types.

Add arch/i386/image/elfboot.c, to handle the generic case of 32-bit
x86 ELF images.  We don't currently set up any multiboot tables, ELF
notes, etc.  This seems to be sufficient for loading kernels generated
using both wraplinux and coreboot's mkelfImage.

Note that while Etherboot 5.4 allowed ELF images to return, we don't.
There is no callback mechanism for the loaded image to shut down gPXE,
which means that we have to shut down before invoking the image.  This
means that we lose device state, protection against being trampled on,
etc.  It is not safe to continue afterwards.

Michael Brown 30cd348689 [SMBIOS] Interpret UUIDs as being in network-endian order 
Various specification documents disagree about the byte ordering of

This doesn't affect anything sent on the wire; only what gets printed on
the screen when the "uuid" variable is displayed.

Michael Brown 1ba959c6b3 [NETDEV] Add notion of link state 
Add ability for network devices to flag link up/down state to the
networking core.

Autobooting code will now wait for link-up before attempting DHCP.

IPoIB reflects the Infiniband link state as the network device link state
(which is not strictly correct; we also need a succesful IPoIB IPv4
broadcast group join), but is probably more informative.

Infiniband devices no longer block waiting for link-up in

Infiniband core needs to reread MAD parameters when link state changes.

IPoIB needs to cope with Infiniband link parameters being only partially

Michael Brown aa74a7d53c [DHCP] Add support for ProxyDHCP requests 
The PXE spec is (as usual) unclear on precisely when ProxyDHCPREQUESTs
should be issued.  We adapt the following, slightly paranoid approach:

  If an offer contains an IP address, then it is a normal DHCPOFFER.

  If an offer contains an option #60 "PXEClient", then it is a
  ProxyDHCPOFFER.  Note that the same packet can be both a normal
  DHCPOFFER and a ProxyDHCPOFFER.

  After receiving the normal DHCPACK, if we have received a
  ProxyDHCPOFFER, we unicast a ProxyDHCPREQUEST back to the ProxyDHCP
  server on port 4011.  If we time out waiting for a ProxyDHCPACK, we
  treat this as a non-fatal error.

Change the PXE return code for EWOULDBLOCK from PXENV_STATUS_FAILURE
to PXENV_STATUS_TFTP_OPEN.  This code is only used by the FILE_READ
PXEXT call, and is necessary to distinguish "error" from "no data" in
that call.

(The only other nonblocking call is UDP_READ, where the caller doesn't
care about the distinction, however, gPXE doesn't use EWOULDBLOCK
internally to represent this condition in that code.)

Michael Brown 5a08b434c7 [Settings] show_setting() functions return snprintf()-style length. 
show_setting() and related functions now return an "actual length" in the
style of snprintf().  This is to allow consumers to allocate buffers large
enough to hold the formatted setting.

Michael Brown b62f2325ba [PXEXT] Add PXENV_FILE_EXEC call to PXE extensions API. 
This allows pxelinux to execute arbitrary gPXE commands.  This is
remarkably unsafe (not least because some of the commands will assume
full ownership of memory and do nasty things like edit the e820 map
underneath the calling pxelinux), but it does allow access to the
"sanboot" command.

Alexey Zaytsev 4006d229e5 Introduce the new timer subsystem. 
Timer subsystem initialization code in core/timer.c

	Split the BIOS and RTDSC timer drivers from i386_timer.c

	Split arch/i386/firmware/pcbios/bios.c into the RTSDC
	timer driver and arch/i386/core/nap.c

	Split the headers properly:
		include/unistd.h - delay functions to be used by the
					gPXE core and drivers.

		include/gpxe/timer.h - the fimer subsystem interface
					to be used by the timer drivers
					and currticks() to be used by
					the code gPXE subsystems.

		include/latch.h	- removed
		include/timer.h - scheduled for removal. Some driver
					are using currticks, which is
					only for core subsystems.

Michael Brown bc3f0a25c6 [Infiniband] Add preliminary support for multi-port devices. 
Arbel and Hermon cards both have multiple ports.  Add the
infrastructure required to register each port as a separate IB
device.  Don't yet register more than one port, since registration
will currently fail unless a valid link is detected.

Michael Brown 4c418d2100 Use net_device_operations structure and netdev_nullify() to allow for 
safe dropping of the netdev ref by the driver while other refs still
exist.

Add netdev_irq() method.  Net device open()/close() methods should no
longer enable or disable IRQs.

Remove rx_quota; it wasn't used anywhere and added too much complexity
to implementing correct interrupt-masking behaviour in pxe_undi.c.
 2007-07-07 16:43:39 +01:00
Michael Brown 934b70d62c Apply global DHCP options when register_dhcp_options() is called. Do

Michael Brown 10d0a1f8c7 Modify data-xfer semantics: it is no longer necessary to call one of 
request(), seek() or deliver_xxx() in order to start the data flow.
Autonomous generators must be genuinely autonomous (having their own

starting the retry timer immediately.

 2007-05-18 14:16:06 +00:00
Michael Brown b1755462ab Do not hold self-references. This then avoids the problem of having to 
ensure that we only drop our self-reference exactly once.

To maintain the guarantee that an object won't go out of scope
unexpectedly while one of its event handlers is being called, the
event-calling functions now automatically obtain and drop extra
references.

Michael Brown 544fa25928 Rename e{malloc,realloc,free} to u{malloc,realloc,free}, to more obviously 
reflect the fact that they allocate and deallocate user memory (i.e.
things reached through a userptr_t).
 2007-01-16 08:36:42 +00:00
Michael Brown ff8528ea9a Create and use async_block() macro; it cuts down on the visual overhead 
of blocking on asynchronous operations, when that isn't an important
aspect of the code.

Michael Brown 9af12d5fba A working DNS resolver (not yet tied in to anything) 2007-01-15 17:31:35 +00:00
Michael Brown df0397f334 Update TFTP and FTP to take the same temporary URI scheme as HTTP 2007-01-15 09:58:26 +00:00
Michael Brown c676591cd1 Unmaintained example code is probably worse than useless. 2007-01-15 09:06:12 +00:00
Michael Brown 4e20d73bb5 Gave asynchronous operations approximate POSIX signal semantics. This 
will enable us to cascade async operations, which is necessary in order to
properly support DNS.  (For example, an HTTP request may have to redirect
to a new location and will have to perform a new DNS lookup, so we can't
just rely on doing the name lookup at the time of parsing the initial
URL).

Anything other than HTTP is probably broken right now; I'll fix the others
up asap.
 2007-01-15 08:49:10 +00:00
Michael Brown 26166cf5e0 Added a URI parser that should be standards conformant. (It can certainly 
handle something as convoluted as

Michael Brown dca369ddc3 Call hide_etherboot() from startup(), rather than requiring the prefix to 
do it.

Michael Brown c2708df14a Make shutdown functions callable by OS image's exec methods. 2007-01-14 00:16:41 +00:00
Michael Brown aaed3d50a8 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

Michael Brown 369754f959 Whitespace fix 2007-01-12 19:17:25 +00:00
Michael Brown 83b7933f8a 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.
 2007-01-12 18:09:14 +00:00
Michael Brown ad22cccc09 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) 2007-01-12 17:08:37 +00:00
Michael Brown b45a9bfa2d Added missing declaration. 2007-01-12 10:07:56 +00:00
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
Michael Brown 39ede8c7e8 Added dhcp() user-level command. 2007-01-12 09:20:11 +00:00

Michael Brown 48e0fc3447 API change: the raw image will no longer be (hypothetically) discarded 
after a call to load().

Michael Brown 6fdc6c81a6 Force probing of multiboot before ELF. 2007-01-12 08:10:35 +00:00
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 
"kernel".

Michael Brown 859da6bd32 Allow external code to update hidden memory regions. 2007-01-12 03:13:04 +00:00
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.
 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 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).
 2007-01-11 16:30:21 +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 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.

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 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 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.
 2006-12-29 00:44:31 +00:00
Michael Brown 61ed298bc7 Merge changes from mcb-tcp-fixes branch. 2006-12-27 23:09:46 +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 ab242a760d Add ability to shut down iSCSI connection 2006-12-21 17:17:47 +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 46c3eeba2a Fix definition of KEY_END 2006-12-20 22:17:44 +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 f8910410fe Add attr_{get,set,on,off} as static inlines. 2006-12-20 06:06:38 +00:00
Michael Brown 8f9336e0c1 Add "config" command to access config UI 2006-12-20 05:37:33 +00:00
Michael Brown b93ff48173 Added descriptive text for settings and setting types, and display it in 
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 4b33c03942 Increase colour pair limit 2006-12-20 03:42:35 +00:00

command is linked in.
 2006-12-19 16:27:15 +00:00
Michael Brown e85bf52446 Avoid cursor move on every single character 2006-12-19 00:51:32 +00:00
Michael Brown edbdce6e3d Now basically functioning on ANSI-supporting consoles. 2006-12-19 00:27:25 +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 8b3a4c9862 Add basic ANSI escape sequence support to BIOS console 2006-12-18 01:19:38 +00:00
Michael Brown 1cd45decc4 Added support for interpreting ANSI escape sequences on behalf of 
non-ANSI-capable consoles.
 2006-12-18 00:01:30 +00:00
Michael Brown a39b111684 Automatically select between the "10" and "16" variants of command set, 
based on the device size.
 2006-12-12 18:54:35 +00:00
Michael Brown 007ca97f25 Added clear_setting() 2006-12-12 15:49:46 +00:00
Michael Brown 72b1629cee Add placeholder ibft.h 2006-12-08 16:16:21 +00:00
Michael Brown c343a3a8ee Including the final (char *)NULL is the responsibility of the caller 
of execl().
 2006-12-08 09:15:12 +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.
 2006-12-08 01:26:11 +00:00

Michael Brown 946967f09c Abstracted out part of the concept of an SPI device to a generalised NVS 
device.

Separated the mechanisms of non-volatile storage access and non-volatile
stored options.
 2006-12-04 18:23:06 +00:00
Michael Brown dc06c895fc Changed length parameter in SPI methods to be a byte length, rather than 
a word length.
 2006-12-04 16:09:59 +00:00
Michael Brown 931f94dca3 Generalised the SPI abstraction layer to also be able to handle interfaces 
that don't provide the full flexibility of a bit-bashing interface.

Temporarily hacked rtl8139.c to use the new interface.
 2006-12-04 15:36:51 +00:00
Michael Brown 2e41bfd268 Force syntax-checking on assertions even in non-asserting builds. 2006-12-04 15:09:57 +00:00
Michael Brown 3e0286dee3 Move ANSI C standard prototypes to stdlib.h; leave the gPXE-specific 
function prototypes (e.g. malloc_dma()) in malloc.h.
 2006-12-02 20:10:21 +00:00
Michael Brown 4cd56820ea Basic non-volatile storage support 2006-11-29 02:41:08 +00:00

information in NVS.
 2006-11-28 02:14:20 +00:00
Michael Brown 3f0b4d9ed8 Updated to use asynchronous operation model for iSCSI requests 
Added CHAP authentication
 2006-11-28 00:29:02 +00:00
Michael Brown 82342e0b8f Marked memcmp/strcmp as "pure" functions, to allow gcc to optimise 
away code such as

  if ( strcmp ( some_string, "some_value" ) != 0 ) {
     DBG ( "Bad value received!" );
  }
 2006-11-27 23:50:24 +00:00
Michael Brown c4677c7e73 Implemented realloc(), and changed the semantics of malloc(0) to allow 
for realloc(0) being a valid way to free memory.
 2006-11-24 16:51:18 +00:00
Michael Brown fdaddd969a Added "name" field to digest algorithms 2006-11-21 16:14:50 +00:00
Michael Brown c5428303e4 Added generic CHAP layer, independent of iSCSI 2006-11-21 13:26:59 +00:00
Michael Brown 57d539aab0 Made it temporarily possible to call MD5 routines directly from external 
code, rather than going through the digest layer.

Removed a spurious line of constants.
 2006-11-15 04:22:22 +00:00
Michael Brown fedc186fd7 Split login into security negotation and operational parameter 
negotiation phases, to allow inclusion of CHAP authentication.
 2006-10-03 09:17:38 +00:00
Michael Brown b16de6ae66 Inhibit compiler warnings on DBG() when building a non-debug object, 
while retaining the format string checking.
 2006-09-27 11:09:56 +00:00
Michael Brown b8baee7632 Removed as a gesture of goodwill following a request from Microsoft 2006-09-18 21:56:15 +00:00
Michael Brown 2f60aa42e7 Killed 2006-09-18 21:55:27 +00:00

Marty Connor e2aca77132 update DBG_DISCARD macro to allow the compiler to see the argument for compile-time checking, while still having it optimized away during compilation 2006-09-14 17:38:17 +00:00
Michael Brown bb8725bffa Added the "swap in place" macros 2006-09-11 17:54:19 +00:00

Michael Brown cf2178f885 Added debug strings. 2006-08-16 00:05:24 +00:00
Michael Brown 97439cb6eb Kill off poll_interruptions(); it is lethal when we're acting as a PXE 
stack or INT 13 emulator etc.
 2006-08-14 22:29:51 +00:00
Michael Brown 7029fb8eff Add string configuration type 2006-08-11 18:16:57 +00:00

include/linux/acpi.h.
 2006-08-10 00:09:31 +00:00
Michael Brown c3a4f3c5da Towards an RFC2988-compliant timer. 2006-08-09 15:54:17 +00:00
Marty Connor ee9ae8130a Remove _PROTOCOL macros for gcc 3.2 compatibility 2006-08-09 04:42:14 +00:00
Michael Brown 75d26d884a Added pxe_netdev; a slight hack for now, but will need to be done 
properly for the PXE UNDI API anyway.
 2006-08-09 02:58:27 +00:00
Michael Brown e9561aafc0 Derive xid dynamically from the netdev, so that we can call 
create_dhcp_packet() from pxe_preboot.c, after the dhcp_session is long
gone.

Expose the functions required by pxe_preboot.c
 2006-08-09 02:56:40 +00:00
Marty Connor 41af7457a8 Merge of Fredrik Hultin command_line 2006-08-09 02:30:35 +00:00
Michael Brown a3d508b648 Clarified packet ownership transfer between a few functions. 
Added a large number of missing calls to free_pkb().  In the case of UDP,
no received packets were ever freed, which lead to memory exhaustion
remarkably quickly once pxelinux started up.

In general, any function with _rx() in its name which accepts a pk_buff
*must* either call free_pkb() or pass the pkb to another _rx() function
(e.g. the next layer up the stack).  Since the UDP (and TCP) layers don't
pass packet buffers up to the higher-layer protocols (the
"applications"), they must free the packet buffer after calling the
application's newdata() method.
 2006-08-09 01:24:32 +00:00
Michael Brown d1a123b1f4 Added TFTP test code (currently just dumps file to console). 2006-08-09 00:09:29 +00:00
Michael Brown 3611cb17b7 Initial (untested) implementation of TFTP over the new UDP API. 2006-08-08 23:45:52 +00:00
Michael Brown eda79ec32b The prototype for strcasecmp() is apparently in strings.h. 2006-08-08 22:52:16 +00:00
Michael Brown 72cd29f13c Added some TFTP definitions for use with the new UDP API. 2006-08-08 22:01:16 +00:00
Michael Brown d12383f1d3 Update to match the daft capitalisation in the actual PXE spec 2006-08-08 20:43:05 +00:00
Michael Brown 68e33224ef gcc3 compatibility: removed ARP_NET_PROTOCOL(). 2006-08-08 17:44:25 +00:00
Nikhil Chandru Rao d2bdf81505 Removed some bugs in TCP 2006-08-08 03:42:30 +00:00
Nikhil Chandru Rao cb42e573a0 Added retransmissions to TCP 2006-08-07 18:52:26 +00:00
Michael Brown ecdcdea1af Remove unused attribute from __table macros; the tables are no longer 
static since otherwise gcc4 optimises them away completely.  Also, it
really *is* an error if the table start and end are unused, so they
certainly shouldn't be marked with attribute unused.
 2006-08-07 17:06:31 +00:00
Michael Brown eb24eece0e Convert some trivial functions to static inlines. 2006-08-03 23:42:03 +00:00
Michael Brown ffe0e24249 Make the UDP senddata() methods return a status code. 
udp_connect() now follows the standard BSD sockets semantics and simply
sets the default address for outgoing packets; it doesn't filter incoming
packets.
 2006-08-03 23:10:14 +00:00
Michael Brown a0a872f7f1 Updated PXE UDP implementation to use the new Etherboot UDP API. 
Updated PXE API dispatcher to use copy_{to,from}_user, and moved to
arch/i386 since the implementation is quite architecture-dependent.
(The individual PXE API calls can be largely
architecture-independent.)
