Recompute them before givin the packet to pfinet. * xen/net.c (recompute_checksum): New function. (hyp_net_intr): Call recompute_checksum when the checksum is blank but the data is validated.

2011-12-17Remove arbitrary limits used by the zone systemRichard Braun
The zone allocator could limit the size of its zones to an arbitrary value set at zinit() time. There is no such parameter with the slab module. As a result of removing those limits, the kern/mach_param.h header becomes empty, and is simply removed altogether. * Makefrag.am (libkernel_a_SOURCES): Remove kern/mach_param.h. * i386/i386/fpu.c: Remove #include <kern/mach_param.h>. * i386/i386/machine_task.c: Likewise. * i386/i386/pcb.c: Likewise. * ipc/ipc_init.c: Likewise.

2011-12-17Remove the defunct kernel_task_create() functionRichard Braun

2011-12-17Adjust VM initializationRichard Braun
Unlike the zone allocator, the slab code can't be fed with an initial chunk of memory. Some VM objects used early during startup now have to be statically allocated, and kernel map entries need a special path to avoid recursion when being allocated. * vm/vm_map.c (vm_submap_object_store): New variable. (vm_submap_object): Point to vm_submap_object_store. (kentry_data_size): Initialize to arbitrary value. (kentry_count): Remove variable. (kentry_pagealloc): New function. (vm_map_setup): Likewise.

(device_io_map): Point to device_io_map_store. (mach_device_init): Call kmem_submap() instead of kmem_suballoc(). * ipc/ipc_init.c (ipc_kernel_map_store): New variable.
