pxelinux: actually stop parsing on a null option

Stop the OACK parsing on a null option, even if it isn't the very
first option.

pxelinux: revert to using TFTP error 8

2009-06-09T15:51:45+00:00

The main reason for ERROR is OACK parsing failure, so revert to using
error code 8 (but a fixed text error.)

pxelinux: cleaner test for OACK trailing null bytes

2009-06-09T14:29:13+00:00

Instead of looking for a string of null bytes at the end of the OACK
string, simply abort parsing if we run into a null byte where an
option is expected; either we are seeing junk at the end of the
packet, or we are hopelessly confused about how to make sense of the
rest of the packet -- in either case, ignoring is the "liberal"
option.

PXELINUX: handle OACK packets with extra NULs, cleaner TFTP error

2009-06-09T05:19:41+00:00

There are apparently TFTP servers in the field which will send OACK
packets with extra NUL bytes appended at the end.  If we find an OACK
packet where the only thing left at some point during processing is
NULs, then just consider the packet processed.

We have reported all TFTP protocol errors as "tsize required", which
is definitely not true anymore.  Change error code to 0 (undefined)
and the error string to "TFTP error".  When this code gets converted
to C we'll do better.

core: prevent buggy INT 13h from leaving IF=0

2009-06-05T00:24:58+00:00

If it can happen for CD-ROM BIOSes, it can probably happen elsewhere,
too; make sure we don't leave interrupts disabled after broken INT 13h
calls.

simple menu: make ONTIMEOUT work with MENU HIDDEN

2009-06-04T16:38:37+00:00

The command invoked when no keys were pressed for the specified time
(ONTIMEOUT) may be different from the menu item initially selected
when the menu is displayed (DEFAULT or MENU DEFAULT).  Unfortunately,
this did not work together with MENU HIDDEN (which is exactly the case
when having a separate ONTIMEOUT command makes the most sense).

bin2hex: actually account for the number of bytes written

2009-06-01T04:53:18+00:00

Unlike C, in Perl printf() doesn't return the number of bytes written.

isohdpfx: actually generate the stack frame isolinux expects

2009-06-01T04:29:59+00:00

Actually generate the stack frame isolinux expects.  This is not the
optimal order, but it appears to be what both earlier and later
versions of isolinux expects...

isolinux: can't clobber edx when dx contains the drive number...

2009-06-01T04:29:12+00:00

Use ebx to hold the upper half of the partition offset, not edx.
