| H A D | bpf_zerocopy.c | diff 180310 Sat Jul 05 18:25:52 MDT 2008 csjp Make sure we are clearing the ZBUF_FLAG_IMMUTABLE any time a free buffer is reclaimed by the kernel. This fixes a bug resulted in the kernel over writing packet data while user-space was still processing it when zerocopy is enabled. (Or a panic if invariants was enabled). Discussed with: rwatson |
