Gustavo A. R. Silva	6f39345768	net: ipv6: Use struct_size() helper and kcalloc() ... Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. Also, remove unnecessary function ipv6_rpl_srh_alloc_size() and replace kzalloc() with kcalloc(), which has a 2-factor argument form for multiplication. This code was detected with the help of Coccinelle and, audited and fixed manually. Signed-off-by: Gustavo A. R. Silva <gustavoars@kernel.org> Signed-off-by: David S.

Alexander Aring	8610c7c6e3	net: ipv6: add support for rpl sr exthdr ... This patch adds rpl source routing receive handling. Everything works only if sysconf "rpl_seg_enabled" and source routing is enabled. Mostly the same behaviour as IPv6 segmentation routing. To handle compression and uncompression a rpl.c file is created which contains the necessary functionality. The receive handling will also care about IPv6 encapsulated so far it's specified as possible nexthdr in RFC 6554. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: David S.
