ipv6: make IPV6_RECVPKTINFO work for ipv4 datagrams

2014-01-20T03:53:18Z

We currently don't report IPV6_RECVPKTINFO in cmsg access ancillary data for IPv4 datagrams on IPv6 sockets. This patch splits the ip6_datagram_recv_ctl into two functions, one which handles both protocol families, AF_INET and AF_INET6, while the ip6_datagram_recv_specific_ctl only handles IPv6 cmsg data. ip6_datagram_recv_*_ctl never reported back any errors, so we can make them return void. Also provide a helper for protocols which don't offer dual personality to further use ip6_datagram_recv_ctl, which is exported to modules. I needed to shuffle the code for ping around a bit to make it easier to implement dual personality for ping ipv6 sockets in future.

transp_v6.h: style neatening

Use a more current code style. Remove extern from function prototypes. Align function arguments and reflow to 80 cols. Use network comment styles. Signed-off-by: Joe Perches cc: Lorenzo Colitti , Signed-off-by: David S. Miller

net: ipv6: Unify {raw,udp}6_sock_seq_show.

2013-06-04T19:56:14Z

udp6_sock_seq_show and raw6_sock_seq_show are identical, except the UDP version displays ports and the raw version displays the protocol. Refactor most of the code in these two functions into a new common ip6_dgram_sock_seq_show function, in preparation for using it to display ICMPv6 sockets as well. Also reduce the indentation in parts of include/net/transp_v6.h to improve readability. Compiles and displays reasonable results with CONFIG_IPV6={n,m,y} Signed-off-by: Lorenzo Colitti Signed-off-by: David S. Miller

Clean up indentation in net/ipv6/transp_v6.h

2013-06-04T19:56:14Z

Reduce the indentation of most of the functions and make it a bit more consistent. This allows longer function and arg names to be consistently indented without wrapping. Signed-off-by: Lorenzo Colitti Signed-off-by: David S. Miller

net: ipv6: Add IPv6 support to the ping socket.

2013-05-26T04:07:49Z

This adds the ability to send ICMPv6 echo requests without a raw socket. The equivalent ability for ICMPv4 was added in 2011. Instead of having separate code paths for IPv4 and IPv6, make most of the code in net/ipv4/ping.c dual-stack and only add a few IPv6-specific bits (like the protocol definition) to a new net/ipv6/ping.c. Hopefully this will reduce divergence and/or duplication of bugs in the future. Caveats: - Setting options via ancillary data (e.g., using IPV6_PKTINFO to specify the outgoing interface) is not yet supported. - There are no separate security settings for IPv4 and IPv6; everything is controlled by /proc/net/ipv4/ping_group_range. - The proc interface does not yet display IPv6 ping sockets properly. Tested with a patched copy of ping6 and using raw socket calls. Compiles and works with all of CONFIG_IPV6={n,m,y}. Signed-off-by: Lorenzo Colitti Signed-off-by: David S. Miller

ipv6: rename datagram_send_ctl and datagram_recv_ctl

2013-01-31T18:53:08Z

The datagram_*_ctl functions in net/ipv6/datagram.c are IPv6-specific. Since datagram_send_ctl is publicly exported it should be appropriately named to reflect the fact that it's for IPv6 only. Signed-off-by: Tom Parkin Signed-off-by: James Chapman Signed-off-by: David S. Miller

net: Remove KERNEL cpp checks from include/net

2011-04-24T17:54:56Z

These header files are never installed to user consumption, so any __KERNEL__ cpp checks are superfluous. Projects should also not copy these files into their userland utility sources and try to use them there. If they insist on doing so, the onus is on them to sanitize the headers as needed.
