I'm not going to be able to send another pull request to Linus before -final, so please respin this against net-next and I'll queue it up for -stable. You can add the missing Fixes: tags as well when you do this. Thanks.
[PATCH net 0/3] validate variable length ll headers
From: Willem de Bruijn 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 replaces ll_header_truncated with dev_validate_header patch 3 implements the protocol specific callback for AX25 Tested with a temporary eth_header_validate function. The AX25 code is compile-tested only at this point.
