* shuffler: when looking for temporary memory, it has to be *free!*syslinux-3.80-pre8H. Peter Anvin2009-05-031-0/+2
| | | | | | | free_area() ended up looking for any area of memory, not necessarily a *free* area of memory. This had predictably disastrous consequences. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* movebits: make the user-space test cases slightly easierH. Peter Anvin2009-05-031-9/+12
| | | | | | | Make it a bit easier to write user-space test cases; use fgets+sscanf so comment lines end up getting ignored. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* shuffler: correctly handle one-to-many relationshipssyslinux-3.80-pre7H. Peter Anvin2009-05-022-26/+133
| | | | | | | | | | | | | | | | | | 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. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* shuffle: align the shuffle safe areaH. Peter Anvin2009-05-021-2/+3
| | | | | | For performance, align the shuffle safe area to a dword boundary. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* syslinux_dump_memmap(): make it easier to spot errorsH. Peter Anvin2009-05-021-1/+1
| | | | | | | | 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. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* syslinux_add_memmap(): fix failures at address zero, more?H. Peter Anvin2009-05-021-38/+63
| | | | | | | | | | | | 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 boundaryH. Peter Anvin2009-05-021-1/+1

* mboot: move setting regs.eax to mboot_run()H. Peter Anvin2009-05-021-2/+1
| | | | | | | The setting of regs.eax in map_image() doesn't really make any sense; move it to mboot_run() instead. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* mboot: move map initialization out of map_image()H. Peter Anvin2009-05-023-35/+38
| | | | | | | | | 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. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* cmenu: add .gitignore fileH. Peter Anvin2009-04-301-0/+2

* linux.c32: move handling of mem= and vga= into the library functionsyslinux-3.80-pre5H. Peter Anvin2009-04-294-78/+99
| | | | | | | Move the handling of mem= and vga= into syslinux_boot_linux(), so that the user of that function doesn't need to worry about it. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

* mboot: include module filenames in the command lineH. Peter Anvin2009-04-281-1/+4
| | | | | | | Grub includes the kernel and module filenames in the command lines it passes, so match that behavior and don't strip them off. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* Unify dependency generation: com32/lib, com32/cmenuH. Peter Anvin2009-04-273-18/+19

* Unify dependency generationH. Peter Anvin2009-04-271-8/+10
| | | | | | | | | | | | Make the dependency generation more common; have a general pattern in MCONFIG, and use it in rules (not in CFLAGS). For NASM source, in order to stay compatible with old versions of NASM, run NASM twice; newer versions of NASM is capable of generating dependencies simultaneously like gcc can, but that would break compatibility with older distros.

* mboot: add header guards; use <inttypes.h>; formatting changesH. Peter Anvin2009-04-272-46/+36
| | | | | | | Reformat the mboot header files slightly, use <inttypes.h> types, and add header inclusion guards. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* mboot/solaris.c: fix failure case; correct copyright noticeH. Peter Anvin2009-04-271-5/+6

* mboot: reimplement the Solaris DHCP hack, add compliant a.out modesyslinux-3.80-pre1H. Peter Anvin2009-04-265-6/+83
| | | | | | | | | | | | | Reimplement the Solaris DHCP information passing hack. Add a spec-compliant mode for the "a.out kludge". The spec is pretty clear that the bit should override the ELF header (after all, otherwise there wouldn't be any need for the bit), but Grub disagrees. We default to Grub-compliant mode, as Solaris seems to set the bit even though it's an ELF kernel, but add the option to enable spec-compliant mode, as apparently some versions of FreeBSD need it.

* mboot: fix cmdline; a few more layout tweaksH. Peter Anvin2009-04-264-30/+38
| | | | | | | | | | Fix module command lines (it was overwriting the main kernel command line); a few minor layout tweaks. In particular, we require the section header to be page-aligned, but not the subsequent sections. With this, I can get Xen to boot. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* mboot: skip --- marker; decompress all filesH. Peter Anvin2009-04-261-7/+5
| | | | | | | | | When walking the argument list we need to skip --- markers. Grub, and the old mboot.c32, seem to transparently decompress all files, not just the main one, so do the same. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* mboot: make sure we actually succeed when we finishedH. Peter Anvin2009-04-262-18/+44
