The separate mtftp.h and mtftp.c files (for doing multicast TFTP)
never really got included into the SLOF repository, so it does
not make sense to keep the "#ifdef USE_MTFTP" code snippets around.

When hitting F12 during boot multiple times (to make sure that you get
to the boot menu), it is sometimes impossible to select a menu entry
from the boot list - you always get the output "Invalid choice!" and
are dropped to the SLOF prompt.
The "boot-start" function already has some code at the beginning to
flush the keyboard input to get rid of multiple F12 keys. But if you
accidentially press F12 again after that code has been executed,
the code that checks the input for the selected boot menu entry
can not handle it and gets confused.
Fix this issue by flushing the keyboard input queue as late as possible
(i.e. after printing the boot menu items, since that could also take
a short while when the list is long and when using slow VGA text
output), and by ignoring all key sequences that start with an ESC
(like the F12 key ESC sequence) in the main keyboard input loop there.

When I tried to abort the net-snk TFTP boot by pressing ESC
a couple of times, I sometimes noticed that SLOF ended up
with a negative stack depth counter. After doing some closer
investigation, I disovered that the problem can be reproduced
by simply pressing "ESC ESC RETURN" at the SLOF prompt.
The problem is in the code in accept.fs: If an ESC character is
found in the input stream, the "handle-ESC" function is called.
This reads in the next input character with "key", and if it
does not match 0x5b or 0x4f, it calls "handle-meta" for further
handling. handle-meta consumes the value from "key" on the stack
to use it as an index into a jump table, thus the stack is empty
now. If the index was a 0x1b (due to the second ESC character),
the function handle-CSI is called. But that function expects
another value as index for a jump table on the stack, and since
the stack was already empty, we end up with a negative stack
depth here.
Apparently, handle-meta should call a function instead that
uses "key" to get another character from the input stream,
before calling the handle-CSI function.

As this was done at byte granularity, erasing complete nvram(64K
default) took a lot of time. To reduce the number of rtas call per byte
write which is expensive, the erase is done at one shot using the
nvram_buffer that is initiated during the nvram_init call for
RTAS_NVRAM.
After this patch there is ~450msec improvement during boot. Default qemu
booting does not provide file backed nvram, so every boot there would be
full erase of 64K.

The whole ethernet frame can be up to 1518 bytes including the ethernet
header. So this value should be used instead of 1500 when the whole
ethernet packet is affected. Since we've already got a nice define
for this value, use ETH_MTU_SIZE where it is appropriate.
This patch also removes a "memset(n->eth_frame, 0, 1500)" in send_ipv6()
to get rid of the magic value 1500 there -- it can be removed since
the whole ethernet packet is filled into the buffer right after the
memset, so there are no gaps that should be cleared first.

The set_ipv6_address() function calls ip6_create_ll_address() to
get a link-local address. The latter function uses malloc to create
a buffer for composing that address, and returns the corresponding
poniter to the caller. However, set_ipv6_address() does not free
that buffer again, so the allocated memory is lost.
Since set_ipv6_address() already allocated space for the new IPv6
address anyway, let's fix this issue by passing the buffer from
set_ipv6_address() to ip6_create_ll_address() instead, so that
ip6_create_ll_address() does not have to allocate memory at all.

The IPv6 code uses malloc in a couple of places to allocate the memory
for a struct. But it does not properly initializes all members of the
struct after the allocation, so the uninitialized members might contain
random data. So we should better clear the whole memory for those
structs to make sure we do not run into some hard-to-reproduce random
problems later.

The "struct neighbor *n" pointer in send_ipv6() can be NULL, e.g.
when we're sending to multicast addresses or to a server that sits
behind a router (since we do not have an entry in the neighbor cache
in this case).
However, the final code in send_ipv6() is always using n->eth_frame
to assemble the ethernet packet, and thus silently writes the data
into the low memory (which happens unnoticed because SLOF does not
use the MMU for memory protection).
This issue is now fixed by using a separate buffer for assembling
those ethernet packets instead. The block for using the router's
MAC address is also moved out of the block that is supposed to handle
the unicast transfers, so that we do not accidentially end up in the
neighbour solicitation code here (which also relies on n != NULL).

The send_ipv6() function should return after doing NDP, since either
the queued packet got send out during handle_na() already, or it has
been stored to be sent out later (once the neighbor advertisment has
been received). If we don't return here, the code runs into the final
send_ether() here later, which then sends out the packet a second time.

The code in send_ipv6() currently basically looks like this:
uint8_t *mac_addr, mac[6];
mac_addr = mac;
...
n = find_neighbor (&ip_dst);
if (ip6_is_multicast (&ip_dst)) {
mac_addr = ip6_to_multicast_mac (&ip_dst, mac);
}
else {
// Check if the MAC address is already cached
if (n) {
if (memcmp(n->mac, null_mac, ETH_ALEN) != 0)
memcpy (mac_addr, &(n->mac), ETH_ALEN);
/* XXX */
}
...
}
...
fill_ethhdr (n->eth_frame, htons(ETHERTYPE_IPv6), get_mac_address(),
mac_addr);
That means mac_addr initially points to the uninitialized mac[6]
array on the stack. Now if there was already an entry in the neighbor
cache, but the MAC address has not been determined yet, that
uninitialized array could be used as final MAC address for fill_ethhdr()
(since there is no "else" path at the spot marked with XXX above),
resulting in random data in the MAC address field of the ethernet packet.
Let's fix this issue by letting mac_addr point to the null_mac by
default instead, so that it never points to invalid data. Also
rename mac[6] to mc_mac[6] to make it clear that this array is
only used for storing the multicast mac address.

Using backspaces after printing out the checkpoint numbers is fine
when printing to terminals. But if the output of SLOF is placed
into a log file instead, this can confuse certain readers like
Firefox to interpret the log file as a binary file instead of text.
To avoid this problem, we can also use '\r' to move the cursor
back to the beginning - this should be fine since the checkpoints
are always printed at the beginning of a line anyway. And '\r' is
then interpreted as normal text, not as a potential binary file byte.

The "read" function of the dev-null device currently claims that
the same amount of bytes has been read as input bytes have been
requested. This causes grub to hang forever at the boot selection
menu, since grub then thinks that there's a continuous stream of input
data. If nothing has been read (which is always the case for the
dev-null device), the "read" function should simply return 0 instead.
Then grub also boots properly again after the typical short timeout.
