Date: Fri, 11 May 2007 06:01:03 -0400 From: "Marc A. Pelletier" <marc@...vesecurity.com> To: netdev@...r.kernel.org Subject: [PATCH 2.6.20] Corrects small word-size dependency in exposed kernel structure Corrects a small word-size dependency in an exposed kernel structure so that mmaped packet sockets will work correctly from 32-bit userspace on a 64-bit kernel. Signed-off-by: Marc A. Pelletier <marc@...vesecurity.com> --- As an aside, I've considered changing the setsockopt() for that feature so that it returns critical values back to userspace (stride between frames, actual offsets of substructures) rather than needing userspace to guess them, but that can't be done without (a) breaking current users of PACKET_RX_RING; or (b) adding a new setsockopt. Which is best? Also, I have a couple of sanity fixes for the ring packet implementation I'd like to discuss. Anyone specific maintaining that bit of code? -- Marc A.
