* Merge syslinux/extlinux patch code and core codeH. Peter Anvin2010-06-201-102/+12
| | | | | | | | Merge the SYSLINUX and EXTLINUX patching code and core code, removing EXTLINUX as a separate derivative. All the disk-based systems now use the same code. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* Reduce sector 1 space pressure; further merge installer codesyslinux-4.00-pre52H. Peter Anvin2010-06-201-130/+32
| | | | | | | | | | Reduce sector 1 space pressure by moving objects that aren't needed by Sector 1 proper into an "extended patch area". While we're mucking with the installer code, make the syslxint and extlinux installer code even more similar. It should now be pretty straightforward to outright merge the code. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* fat: fix off-by-one error in the FAT installersyslinux-4.00-pre51H. Peter Anvin2010-06-201-3/+4
| | | | | | | Fix off-by-one error in the FAT installer, which caused the install to incorrectly abort without the patched version of the data. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* dos: fix get_64_sl() and set_64_sl()H. Peter Anvin2010-06-151-5/+2
| | | | | | | We must make sure we actually use the modified pointer returned from set_fs(), otherwise bad things happen... Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
* Fix prototype for generate_extentsH. Peter Anvin2010-06-151-1/+1

* syslinux: synchronize generate_extents() with extlinuxH. Peter Anvin2010-06-151-16/+15
| | | | | | Synchronize the code for generate_extents() from extlinux to syslinux. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
* Switch to 64-bit sector pointers everywhereH. Peter Anvin2010-06-151-30/+114
| | | | | | | | | | | | Switch to consistent use of 64-bit sector pointers; this should enable booting even for individual *partitions* larger than 2 TB. In order to not slow down the boot too much, switch the initial load from an enumeration to an extent map. This means the table gets larger (since we have to assume the worst case), but it simplifies the Sector 1 code (since we can push all the hard stuff into the installer), and will speed up booting in the general case.

* Implement !GPT protocol in Syslinux core; handle offset > 2 TBH. Peter Anvin2010-06-141-7/+8
| | | | | | | | | | | | | | | Implement the !GPT handover protocol in the Syslinux core, and handle partition offsets above 2 TB. We do not yet handle filesystem sizes above 2 TB, but that should be a reasonably straightforward extension at this time (need to switch to 8-byte block pointers). This finally meant moving getlinsec out of the boot sector, since it no longer fits. Instead have a very simple getonesec implementation in the boot sector. getlinsec still fits in Sector 1, although it doesn't leave space for very many block pointers. That's still better than adding yet another boot loader stage, however. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
* Clean up warnings in previous checkinH. Peter Anvin2010-06-091-2/+3

* Make syslinux installer real "pathbased"Alek Du2010-06-091-11/+21
| | | | | | | | | | | | | The previous merging extlinux/syslinux patch is not sufficient, the syslinux is not real "patchbased", hence: * fill currentdir in patcharea * search "extlinux.conf" and "syslinux.cfg" for generic_load_config * define boot_image and boot_sector macro for ldsyslinux this could make further merging extlinux and syslinux possible Signed-off-by: Alek Du <alek.du@intel.com> Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
* unify common parts of extlinux and syslinux installerAlek Du2010-05-201-1/+2
| | | | | | | | | | | Thus we can share same command line options and reduce a lot of dup code... Seems like a big patch, but the changes are quite safe, no much logical change. Signed-off-by: Alek Du <alek.du@intel.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* syslinux: fix sector arraysAlek Du2010-05-201-1/+1
| | | | | | | | | The first sector ptr is in bs->NextSector not in the array in the patch_area. And actually the ADV sectors counting is wrong for a while ... Signed-off-by: Alek Du <alek.du@intel.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| * FAT: be more explicit why we think a filesystem is badH. Peter Anvin2010-01-241-14/+21
| | | | | | | | | | | | | | | | Give readable error messages as to why we think a filesystem is bad. Given the current sizes of the installer, these extra strings are worth it. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* | core: initial work on path-based cwd selectionH. Peter Anvin2010-01-061-1/+0
|/ | | | | | | | | | | Work on picking the initial cwd by storing a path instead of by storing an inode number. This should be both more general (in the sense of supporting filesystems in a generic way) as well as conceptually cleaner. The code doesn't work yet, but this at least provides support for the extlinux installer to store its subpath into the installed image. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

* | FAT: change DOS installer to EXE; additional 32K limit fixesH. Peter Anvin2009-05-191-16/+104
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Additional fixes for the 32K limits in the installers. In the case of the DOS installer, that means changing it from COM format to EXE format (since COM format has a 63K hard limit); retain the name syslinux.com for user compatibility, though (DOS doesn't care what the extension except for pathname search; if it finds an MZ EXE header it will use it.) With the change to EXE means having to handle more than one segment. Since we don't have a real DOS compiler we have to wing it a bit. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* | libinstaller: "nsect" is the size of ldlinux.sys, not the totalH. Peter Anvin2009-05-191-1/+0
| | | | | | | | | | | | | | | | | | | | "nsect" here is the size of ldlinux.sys, not the total structure; therefore it should not be decremented. Again, all this should really be unified. With this patch the FAT derivatives boot with the current code. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* | FAT: update the FAT installers to match the new diskstart.incH. Peter Anvin2009-05-191-150/+53
|/ | | | | | | | | | | | Update the FAT installers to match the new patch area format in diskstart.inc. Also, update the coding style to match extlinux; this code should eventually get unified. This does not resolve the current issues with the DOS installer when ldlinux.sys exceeds about 48K, at which point the DOS installer needs to become a segment-aware EXE program. Signed-off-by: H.

--once now supported for extlinux; some infrastructure for syslinux there as well, need implementation in all the various installers, however.
