PXELINUX: Fix IPAPPEND to include BOOTIF and SYSUUID

2013-01-14T12:16:38+00:00

commit 14531c47bc95 ("core: Delete code that is duplicated in
ldlinux") erroneously deleted the BOOTIFStr and SYSUUIDStr entries
from the PXELINUX-version of IPAppends, meaning that IPAPPEND 3 and
IPAPPEND 4 didn't append the corresponding strings to the command
line.

isolinux: Update LBA in getlinsec loop

2013-01-11T08:39:27+00:00

We need to increment the Logical Block Address in eax by the number of
sectors we passed to getlinsec after every invocation, otherwise we'll
start with the same sector everytime.

This bug was discovered when booting an isohybrid image, which failed
to boot after printing the following error,

    "Image checksum error, sorry..."

because the isolinux.bin was bigger than 32K, and thus invoked the
getlinsec loop that reads the file in chunks.

core/kaboom.c: Export __bad_SEG()

2013-01-08T15:40:31+00:00

We need to add __bad_SEG() to the symbol export whitelist, otherwise
ldlinux.c32 will fail to load if compiled with -DDEBUG=1 due to not
being able to resolve __bad_SEG().

Delete 16-bit COMBOOT support

2012-12-06T10:47:31+00:00

16-bit COMBOOT files are no longer supported by Syslinux in 5.00 so
delete all references and change any 32-bit COMBOOT image references
to mention ELF instead.

Some of the COMBOOT stuff is still used internally so we can't nuke
core/comboot.inc yet, but that will disappear in a future release.

Symbol export whitelist

2012-12-05T22:41:32+00:00

Before modules were dynamically loaded the boundary between GPL and
non-GPL code was implicit because of the separate link domains for
each module. With dynamic modules we need an explicit whitelist of
core symbols that non-GPL code can link against at runtime without
needing to be re-licensed under the GPL.

Mark such symbols with __export, so that it is explicitly clear which
symbols in the core can be linked against by non-GPL code.

Reduce the visibility of symbols in both the core and ldlinux.c32 with
-fvisibility=hidden. __export changes the visibility to 'default'.

core: Fix 'NoHalt'

Use the same variable in idle.c and ldlinux.c32.

Reduce the number of global variables

2012-12-05T20:07:11+00:00

In preparation for strictly limiting the list of variables that are
exported (global) in the core, delete any unused variables, rewrite
variable declarations in C that are not referenced by asm and delete
files that are no longer included in other asm files.

comboot: Mark API functions obsolete

2012-12-05T20:06:27+00:00

Starting with Syslinux 5.00 the COMBOOT API is obsolete and should not
be used by any modules. It is still used internally for some things,
such as the ADV code in ldlinux.c32, but that will change in the
future.

ldlinux: Move DISPLAY file handling out of the core

2012-12-03T13:54:46+00:00

The code that handles the DISPLAY directive was writing directly to
the BIOS VGA page with __intcall(0x10). This caused corruption
problems on the screen because the ansi library code was also writing
to the screen.

The correct way to fix this is to always use the ansi library code
(via printf()) instead of going behind its back and using separate
code paths to write to the screen.
