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'.

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.

pxe: move hardwired DHCP options into high memory

2012-05-29T19:22:32+00:00

If we have hardwired DHCP options, move them into high memory instead
of into the trackbuf.  This eliminates yet another trackbuf user.

core: Delete the aux segment

2012-03-23T16:34:41+00:00

We don't need to use a special aux segment because we can represent
'fontbuf' with OFFS() and SEG(). We're guaranteed to be able to break
the 32-bit pointer up with these macros because we control where in
the address space the core is loaded. (Not all 32-bit pointers can be
represented with OFFS() and SEG(), only addresses in the range
0..0xFFFFF.)

This fixes the breakage that was introduced in commit 14531c47bc95
("core: Delete code that is duplicated in ldlinux").

This allows the default font to be displayed. Previously junk was
being returned in the COMBOOT API call to query the userfont, leading
the caller to believe that a user font was installed even when it
wasn't.

core: layout.inc: remove duplicate .stack segment definition

2011-04-25T23:36:36+00:00

.stack was redefined for unknown reasons.  This is not present in the
master branch.

core: add .stack16 to layout.inc

2011-04-10T01:27:07+00:00

It seems to get the right flags by default, but since .stack needed it
we might as well put in .stack16 too...

core: add .stack to layout.inc so it gets the proper flags

2011-04-10T01:27:07+00:00

Add the .stack segment to layout.inc even as just a dummy, so that we
end up with the correct flags in the output.

core: use assembly for the .stack section

2010-03-07T05:29:47+00:00

Use assembly to define the .stack section, so that it get proper
attributes.

core: use better malloc; add low memory malloc; fix com32 exit

2010-02-24T06:32:32+00:00

Use a better malloc for the core.  In particular, use the same core
that we should eventually be able to use for the entire system in
Syslinux 5 -- with module awareness, etc.

This code can also accommodate multiple heaps.  Set up a separate heap
for lowmem; the intent is to use explicit lowmem allocations instead
of the static bounce buffer.  The lowmem allocation is also exported
via the pmapi mechanism, so modules can safely allocate lowmem.
