ipv6: Handle PMTU in ICMP error handlers. One tricky issue on the ipv6 side vs. ipv4 is that the ICMP callouts to handle the error pass the 32-bit info cookie in network byte order whereas ipv4 passes it around in host byte order. Like the ipv4 side, we have two helper functions. One for when we have a socket context and one for when we do not. ip6ip6 tunnels are not handled here, because they handle PMTU events by essentially relaying another ICMP packet-too-big message back to the original sender. This patch allows us to get rid of rt6_do_pmtu_disc(). It handles all kinds of situations that simply cannot happen when we do the PMTU update directly using a fully resolved route. In fact, the "plen == 128" check in ip6_rt_update_pmtu() can very likely be removed or changed into a BUG_ON() check. We should never have a prefixed ipv6 route when we get there. Another piece of strange history here is that TCP and DCCP, unlike in ipv4, never invoke the update_pmtu() method from their ICMP error handlers. This is incredibly astonishing since this is the context where we have the most accurate context in which to make a PMTU update, namely we have a fully connected socket and associated cached socket route.

net: inet: Support UID-based routing in IP protocols. - Use the UID in routing lookups made by protocol connect() and sendmsg() functions. - Make sure that routing lookups triggered by incoming packets (e.g., Path MTU discovery) take the UID of the socket into account. - For packets not associated with a userspace socket, (e.g., ping replies) use UID 0 inside the user namespace corresponding to the network namespace the socket belongs to. This allows all namespaces to apply routing and iptables rules to kernel-originated traffic in that namespaces by matching UID 0. This is better than using the UID of the kernel socket that is sending the traffic, because the UID of kernel sockets created at namespace creation time (e.g., the per-processor ICMP and TCP sockets) is the UID of the user that created the socket, which might not be mapped in the namespace.

xfrm: delete x->tunnel as we delete x The ipcomp fallback tunnels currently get deleted (from the various lists and hashtables) as the last user state that needed that fallback is destroyed (not deleted). If a reference to that user state still exists, the fallback state will remain on the hashtables/lists, triggering the WARN in xfrm_state_fini. Because of those remaining references, the fix in commit f75a2804da39 ("xfrm: destroy xfrm_state synchronously on net exit path") is not complete. We recently fixed one such situation in TCP due to defered freeing of skbs (commit 9b6412e6979f ("tcp: drop secpath at the same time as we currently drop dst")). This can also happen due to IP reassembly: skbs with a secpath remain on the reassembly queue until netns destruction. If we can't guarantee that the queues are flushed by the time xfrm_state_fini runs, there may still be references to a (user) xfrm_state, preventing the timely deletion of the corresponding fallback state. Instead of chasing each instance of skbs holding a secpath one by one, this patch fixes the issue directly within xfrm, by deleting the fallback state as soon as the last user state depending on it has been deleted. Destruction will still happen when the final reference is dropped. A separate lockdep class for the fallback state is required since we're going to lock x->tunnel while x is locked.

[IPSEC]: Fix tunnel error handling in ipcomp6 The error handling in ipcomp6_tunnel_create is broken in two ways: 1) If we fail to allocate an SPI (this should never happen in practice since there are plenty of 32-bit SPI values for us to use), we will still go ahead and create the SA. 2) When xfrm_init_state fails, we first of all may trigger the BUG_TRAP in __xfrm_state_destroy because we didn't set the state to DEAD.

[IPSEC]: Forbid BEET + ipcomp for now While BEET can theoretically work with IPComp the current code can't do that because it tries to construct a BEET mode tunnel type which doesn't (and cannot) exist. In fact as it is it won't even attach a tunnel object at all for BEET which is bogus. To support this fully we'd also need to change the policy checks on input to recognise a plain tunnel as a legal variant of an optional BEET transform.

xfrm: add extack to xfrm_init_state Add a struct extack parameter to xfrm_init_state() and pass it through to __xfrm_init_state(). This allows validation errors detected during state initialization to propagate meaningful error messages back to userspace. xfrm_state_migrate() now passes extack so that errors from the XFRM_MSG_MIGRATE_STATE path are properly reported. Callers without an extack context (af_key, ipcomp4, ipcomp6) pass NULL, preserving their existing behaviour.

[IPSEC]: Fix tunnel error handling in ipcomp6 The error handling in ipcomp6_tunnel_create is broken in two ways: 1) If we fail to allocate an SPI (this should never happen in practice since there are plenty of 32-bit SPI values for us to use), we will still go ahead and create the SA. 2) When xfrm_init_state fails, we first of all may trigger the BUG_TRAP in __xfrm_state_destroy because we didn't set the state to DEAD. More importantly we end up returning the freed state as if we succeeded! This patch fixes them both. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

Linux-2.6.12-rc2 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!

[XFRM]: Add module alias for transformation type. It is clean-up for XFRM type modules and adds aliases with its protocol: ESP, AH, IPCOMP, IPIP and IPv6 for IPsec ROUTING and DSTOPTS for MIPv6 It is almost the same thing as XFRM mode alias, but it is added new defines XFRM_PROTO_XXX for preprocessing since some protocols are defined as enum.
