shuffler: when looking for temporary memory, it has to be free!

2009-05-03T22:23:01+00:00

free_area() ended up looking for any area of memory, not necessarily a
*free* area of memory.  This had predictably disastrous consequences.

movebits: make the user-space test cases slightly easier

2009-05-03T22:07:52+00:00

Make it a bit easier to write user-space test cases; use fgets+sscanf
so comment lines end up getting ignored.

shuffler: correctly handle one-to-many relationships

2009-05-03T00:27:03+00:00

One-to-many relationships, in which one chunk of a file is used in
more than one place, tends to naturally show up in decoding certain
fileformats, including (but not limited to) Microsoft SDI.  Make the
shuffler library handle those cases correctly, and remove a
special-purpose hack in sdi.c.

This is based on the observation that all one-to-many relationships
can be treated as a one-to-one shuffle followed by
destination-to-destination copies; i.e. one copy is (arbitrarily)
assigned the "master copy" status, and all aliases are then copied
from the master copy when the master copy is already in its final
place.  All other copies can then be simply ignored for the duration
of the shuffle, just as zero-memory is.

syslinux_dump_memmap(): make it easier to spot errors

2009-05-03T00:00:38+00:00

Instead of stopping the memmap dump on SMT_END, stop it only on a null
pointer.  That way we can see if we have any bogus entries with
SMT_END.

syslinux_add_memmap(): fix failures at address zero, more?

2009-05-02T23:58:46+00:00

syslinux_add_memmap() would fail miserably and corrupt the list if an
entry was added at address zero.  Quite possibly other addresses would
have similar problems.  Furthermore, we did an extra "optimization
pass" which should never have been necessary if the algorithm had been
correct in the first place.

This should hopefully fix ALL those bugs.

mboot: align the stack to a 16-byte boundary

Align the stack to a 16-byte boundary, just in case...

mboot: move setting regs.eax to mboot_run()

2009-05-02T20:52:04+00:00

The setting of regs.eax in map_image() doesn't really make any sense;
move it to mboot_run() instead.

mboot: move map initialization out of map_image()

2009-05-02T20:50:17+00:00

The amap/mmap initialization were buried randomly inside map_image(),
which at the very least makes the code needlessly hard to read.
Furthermore, it is at least possible that we may want to be able to
map multiple images in the future.
