Preserve the whole of %esp across prot_call(). We have to split this
...
between the low half stored in the static variable rm_sp, and the high
half stored on the prot_call() stack, because:
Just using the stack would screw up when a prot_call()ed routine
executes a real_call(); it would have no way to find the current top of
the RM stack.
Extending rm_sp to rm_esp would not be safe, because the guarantee that
rm_sp must return to the correct value by the time an external
real-mode call returns applies only to %sp, not to %esp.

Add infrastructure to support access to .data16 (and .text16) variables
...
from protected-mode code.
Set up %ds to point to .data16 in prot_to_real, so that code specified
via REAL_EXEC() and friends can access variables in .data16.
Move most real-mode librm variables from .text16 to .data16.
2006-05-04 23:14:06 +00:00

Added methods for efficiently declaring and accessing variables in

address of the start of .data16.

BSS is now zeroed by libprefix (along with the otherwise non-zeroable

init_fns() are called from main(). We need to think about initial

Change semantics of network API so that packet-absorbing calls *always*
...
take ownership of the packet, rather than doing so only if they return
success. This breaks semantic compatibility with Linux's
hard_start_xmit() method, but means that we don't have to worry so much
about error cases.
Split mechanism of processing received packets (net_rx_process()) out
from policy (net_step()), preparatory to putting net_step() in a separate
object.
