Abstract:
Methods and apparatus provide for receiving a request for memory from a network stack subsystem running in user mode. The request is received at a listing of pointers that resides within the network stack but separate from kernel memory. Each available pointer in the listing of pointers references a particular free kernel memory location. In response to the request, the listing of pointers provides the network stack subsystem with at least one pointer to a free kernel memory location. Via the pointer, the network stack subsystem that received the pointer to the free kernel memory location directly writes at least one segment of a packet to the free kernel memory location.
