Access to the gpxe.org and etherboot.org domains and associated
resources has been revoked by the registrant of the domain. Work
around this problem by renaming project from gPXE to iPXE, and
updating URLs to match.
Also update README, LOG and COPYRIGHTS to remove obsolete information.

Christopher Armenio reported link detection problems with an
integrated eepro100 NIC. Thomas Miletich removed link detection code
from the eepro100 driver and verified that the driver continued to
function. Christopher verified Thomas' patch on his integrated

gPXE currently overwrites the filename stored in the cached DHCP
packets when a call to PXENV_TFTP_READ_FILE or PXENV_RESTART_TFTP is
made. This code has existed for many years as a workaround for RIS,
which seemed to require that this be done.
pxe_set_cached_filename() causes problems with the Bootix NBP, and a
recent test demonstrates that RIS will complete successfully even with
pxe_set_cached_filename() removed. There have been many changes to
the DHCP and PXE logic since this code was first added, and it is
quite plausible that it was masking a bug that no longer exists.

Current gPXE code always returns "OURS" in response to
PXENV_UNDI_ISR:START. This is harmless for non-shared interrupt
lines, and avoids the complexity of trying to determine whether or not
we really did cause the interrupt. (This is a non-trivial
determination; some drivers don't have interrupt support and hook the
system timer interrupt instead, for example.)
A problem occurs when we have a shared interrupt line, the other
device asserts an interrupt, and the controlling ISR does not chain to
the other device's ISR when we return "OURS". Under these
circumstances, the other device's ISR never executes, and so the
interrupt remains asserted, causing an interrupt storm.
Work around this by returning "OURS" if and only if our net device's
interrupt is currently recorded as being enabled. Since we always
disable interrupts as a result of a call to PXENV_UNDI_ISR:START, this
guarantees that we will eventually (on the second call) return "NOT
OURS", allowing the other ISR to be called. Under normal operation,
including a non-shared interrupt situation, this change will make no
difference since PXENV_UNDI_ISR:START would be called only when
interrupts were enabled anyway.

The function recorder is a crash and hang debugging tool. It logs each
function call into a memory buffer while gPXE runs. After the machine
is reset, and if the contents of memory have not been overwritten, gPXE
will detect the memory buffer and print out its contents.
This allows developers to see a trace of the last functions called
before a crash or hang. The util/fnrec.sh script can be used to convert
the function addresses back into symbol names.
To build with fnrec:
make FNREC=1

Loading multiple UNDI instances would be useful in systems that have
several network cards with vendor PXE ROMs. However, we cannot rely on
UNDI ROMs working correctly with multiple instances loaded
simultaneously.
The gPXE UNDI driver supports the following multi-NIC configurations:
1. Chainloading undionly.kpxe on a specific NIC.
2. Loading the UNDI driver for the first probed device and ignoring all
other UNDI devices in the system.
This patch refuses to probe additional UNDI devices so there can never
be multiple instances of UNDI loaded.

It might be the case that we wish to chain to an NBP without
being "in the way". We now implement a hook in our exit path
for gPXE *.*pxe build targets. The hook is a pointer to a
SEG16:OFF16 which we try to jump to during exit. By default,
this pointer results in the usual exit path.
We also implement the "pxenv_file_exit_hook" PXE API routine
to allow the user to specify an alternate SEG16:OFF16 to jump
to during exit.
Unfortunately, this additional PXE extension has a cost
in code size. Fortunately, a look at the size difference
for a gPXE .rom build target shows zero size difference
after compression.
The routine is documented in doc/pxe_extensions as follows:
FILE EXIT HOOK
Op-Code: PXENV_FILE_EXIT_HOOK (00e7h)
Input: Far pointer to a t_PXENV_FILE_EXIT_HOOK parameter
structure that has been initialized by the caller.
Output: PXENV_EXIT_SUCCESS or PXENV_EXIT_FAILURE must be
returned in AX. The Status field in the parameter
structure must be set to one of the values represented
by the PXENV_STATUS_xxx constants.
Description:Modify the exit path to jump to the specified code.
Only valid for pxeprefix-based builds.
typedef struct s_PXENV_FILE_EXIT_HOOK {
PXENV_STATUS_t Status;
SEGOFF16_t Hook;
} t_PXENV_FILE_EXIT_HOOK;
Set before calling API service:
Hook: The SEG16:OFF16 of the code to jump to.
Returned from API service:
Status: See PXENV_STATUS_xxx constants.

Instead of keeping only the best IP and PXE offers, store all of them,
and pick the best to use just before a request is sent. This allows
priority differentiation to work even when lower-priority offers
provide PXE options, and improves robustness at sites with broken PXE
servers intermingled with working ones: when a ProxyDHCP request times
out, instead of giving up, we try the next PXE offer we've received.
It also allows us to avoid breaking up combined IP+PXE offers, which
can be important with some firewall configurations. This behavior
matches that of most vendor PXE ROMs.
Store a reference to the DHCPOFFER packet in the offer structure, so
that when registering settings after a successful ACK we can register
the proxy PXE settings we originally received; this removes the need
for a nonstandard duplicate REQUEST/ACK to port 67 of proxy servers
like dnsmasq that provide PXE options in the OFFER.
Total cost: 450 bytes uncompressed.

Currently, handling of URI escapes is ad-hoc; escaped strings are
stored as-is in the URI structure, and it is up to the individual
protocol to unescape as necessary. This is error-prone and expensive
in terms of code size. Modify this behavior by unescaping in
parse_uri() and escaping in unparse_uri() those fields that typically
handle URI escapes (hostname, user, password, path, query, fragment),
and allowing unparse_uri() to accept a subset of fields to print so
it can be easily used to generate e.g. the escaped HTTP path?query
request.

A script loaded via autoboot may want to get some of the settings (MAC
address, IP address, et cetera) for the interface via which it was
loaded, in order to pass them to the operating system. Previously such
a script had no way to determine what to put in the X of ${netX/foo}.
Solve this problem by transparently forwarding accesses to the real
settings associated with the most recently opened network device,
so scripts in this situation can say literally ${netX/foo} and get
the foo setting they want.

The standard option ROM format provides a header indicating the size
of the entire ROM, which the BIOS will reserve space for, load, and
call as necessary. However, this space is strictly limited to 128k for
all ROMs. gPXE ameliorates this somewhat by reserving space for itself
in high memory and relocating the majority of its code there, but on
systems prior to PCI3 enough space must still be present to load the
ROM in the first place. Even on PCI3 systems, the BIOS often limits the
size of ROM it will load to a bit over 64kB.
These space problems can be solved by providing an artificially small
size in the ROM header: just enough to let the prefix code (at the
beginning of the ROM image) be loaded by the BIOS. To the BIOS, the
gPXE ROM will appear to be only a few kilobytes; it can then load
the rest of itself by accessing the ROM directly using the PCI
interface reserved for that task.
There are a few problems with this approach. First, gPXE needs to find
an unmapped region in memory to map the ROM so it can read from it;
this is done using the crude but effective approach of scanning high
memory (over 0xF0000000) for a sufficiently large region of all-ones
(0xFF) reads. (In x86 architecture, all-ones is returned for accesses
to memory regions that no mapped device can satisfy.) This is not
provably valid in all situations, but has worked well in practice.
More importantly, this type of ROM access can only work if the PCI ROM
BAR exists at all. NICs on physical add-in PCI cards generally must
have the BAR in order for the BIOS to be able to load their ROM, but
ISA cards and LAN-on-Motherboard cards will both fail to load gPXE
using this scheme.
Due to these uncertainties, it is recommended that .xrom only be used
when a regular .rom image is infeasible due to crowded option ROM
space. However, when it works it could allow loading gPXE images
as large as a flash chip one could find - 128kB or even higher.

For extremely tight space requirements and specific applications, it is
sometimes desirable to create gPXE images that cannot provide the PXE API
functionality to client programs. Add a configuration header option,
PXE_STACK, that can be removed to remove this stack. Also add PXE_MENU
to control the PXE boot menu, which most uses of gPXE do not need.

If we don't unload the PXE stack before executing gPXE, automatically
take advantage of the cached DHCPACK that the underlying/parent PXE
stack can provide. If that cached DHCPACK contains option 175.178, or
the user sets the use-cached setting before invoking DHCP, the real
DHCP request will be skipped and the cached DHCPACK will be used for
network configuration. Otherwise, the cached settings block is thrown
away as soon as a fresh one is acquired.
