Miller <davem@davemloft.net> commit 515b76147e907579254cd5997a4ab9e64da32268 Author: Lorenzo Colitti <lorenzo@google.com> Date: Wed Jan 16 22:09:49 2013 +0000 net: ipv6: Add IPv6 support to the ping socket. [backport of net-next 6d0bfe22611602f36617bc7aa2ffa1bbb2f54c67] 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}.

In the IP header of the ACK message, we choose to reflect TOS field of incoming message, and this might break some setups. Example of things that were broken : - Routing using TOS as a selector - Firewalls - Trafic classification / shaping We now remember in timewait structure the inet tos field and use it in ACK generation, and route lookup. Notes : - We still reflect incoming TOS in RST messages. - We could extend MuraliRaja Muniraju patch to report TOS value in netlink messages for TIME_WAIT sockets. - A patch is needed for IPv6 Change-Id: Ic7ad8a7b858de181bfe2a789c472f84955397d4c Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

* ipv6: make fragment identifications less predictableEric Dumazet2011-08-151-0/+2
| | | | | | | | | | | | | | | | | | | | | [ Backport of upstream commit 87c48fa3b4630905f98268dde838ee43626a060c ] Fernando Gont reported current IPv6 fragment identification generation was not secure, because using a very predictable system-wide generator, allowing various attacks. IPv4 uses inetpeer cache to address this problem and to get good performance. We'll use this mechanism when IPv6 inetpeer is stable enough in linux-3.1 For the time being, we use jhash on destination address to provide less predictable identifications. Also remove a spinlock and use cmpxchg() to get better SMP performance. Reported-by: Fernando Gont <fernando@gont.com.ar> Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

* net: Remove __KERNEL__ cpp checks from include/netDavid S. Miller2011-04-241-4/+0
| | | | | | | | | | | 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.

* [IPV6]: make the protocol initialization to return an error codeDaniel Lezcano2008-01-281-4/+8
| | | | | | | | | | | | | This patchset makes the different protocols to return an error code, so the af_inet6 module can check the initialization was correct or not. The raw6 was taken into account to be consistent with the rest of the protocols, but the registration is at the same place. Because the raw6 has its own init function, the proto and the ops structure can be moved inside the raw6.c file. Signed-off-by: Daniel Lezcano <dlezcano@fr.ibm.com> Signed-off-by: David S.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
