Boot loader network stack never cleaned up
|Reported by:||andreasf||Owned by:||jessicah|
|Has a Patch:||no||Platform:||All|
The boot loader's network stack, currently used for OpenFirmware and PXE only, is not cleaned up before entering the kernel.
With #5193 patches on ppc the OpenFirmware memory is successfully retained while unmapping the boot loader memory (including its network stack) along with any non-kernel memory. The
dma-alloc'ed send/receive buffer is retained inside OpenFirmware though (here 0xff9d1000-0xff9d3000 and OpenFirmware at 0xff800000-0xffa00000), with no proper way to access or free the memory afterwards.
