From: Willem de Bruijn <will...@google.com> Allow device-specific validation of link layer headers. Existing checks drop all packets shorter than hard_header_len. For variable length protocols, such packets can be valid.
patch 1 adds header_ops.validate and dev_validate_header patch 2 implements the protocol specific callback for AX25 patch 3 replaces ll_header_truncated with dev_validate_header Willem de Bruijn (3): net: validate variable length ll headers ax25: add link layer header validation function packet: validate variable length ll headers include/linux/netdevice.h | 22 ++++++++++++++++++++-- net/ax25/ax25_ip.c | 15 +++++++++++++++ net/packet/af_packet.c | 43 ++++++++++++++++++------------------------- 3 files changed, 53 insertions(+), 27 deletions(-) -- 2.7.0.rc3.207.g0ac5344
