* [IPV6] ADDRCONF: Support RFC3484 configurable address selection policy table.YOSHIFUJI Hideaki2008-01-28
| | | | | | | | Policy table is implemented as an RCU linear list since we do not expect large list nor frequent updates. Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: David S. Miller <davem@davemloft.net>

* [NETFILTER]: Introduce NF_INET_ hook valuesPatrick McHardy2008-01-28
| | | | | | | | | | | The IPv4 and IPv6 hook values are identical, yet some code tries to figure out the "correct" value by looking at the address family. Introduce NF_INET_* values for both IPv4 and IPv6. The old values are kept in a #ifndef __KERNEL__ section for userspace compatibility.

* [IPSEC]: Add async resume support on inputHerbert Xu2008-01-28
| | | | | | | | | This patch adds support for async resumptions on input. To do so, the transform would return -EINPROGRESS and subsequently invoke the function xfrm_input_resume to resume processing.

* [IPSEC]: Remove nhoff from xfrm_inputHerbert Xu2008-01-28
| | | | | | | | | | | | | | | | | | The nhoff field isn't actually necessary in xfrm_input. For tunnel mode transforms we now throw away the output IP header so it makes no sense to fill in the nexthdr field. For transport mode we can now let the function transport_finish do the setting and it knows where the nexthdr field is. The only other thing that needs the nexthdr field to be set is the header extraction code. However, we can simply move the protocol extraction out of the generic header extraction. We want to minimise the amount of info we have to carry around between transforms as this simplifies the resumption process for async crypto.

* [IPSEC]: Make x->lastused an unsigned longHerbert Xu2008-01-28
| | | | | | | | | | | | | | Currently x->lastused is u64 which means that it cannot be read/written atomically on all architectures. David Miller observed that the value stored in it is only an unsigned long which is always atomic. So based on his suggestion this patch changes the internal representation from u64 to unsigned long while the user-interface still refers to it as u64.

* [IPSEC]: Move state lock into x->type->inputHerbert Xu2008-01-28
| | | | | | | | | | | | This patch releases the lock on the state before calling x->type->input. It also adds the lock to the spots where they're currently needed. Most of those places (all except mip6) are expected to disappear with async crypto. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPSEC]: Move integrity stat collection into xfrm_inputHerbert Xu2008-01-28
| | | | | | | | | | | | | | | | Similar to the moving out of the replay processing on the output, this patch moves the integrity stat collectin from x->type->input into xfrm_input. This would eventually allow transforms such as AH/ESP to be lockless. The error value EBADMSG (currently unused in the crypto layer) is used to indicate a failed integrity check. In future this error can be directly returned by the crypto layer once we switch to aead algorithms. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPSEC]: Store xfrm states in security path directlyHerbert Xu2008-01-28
| | | | | | | | | | | | | | As it is xfrm_input first collects a list of xfrm states on the stack before storing them in the packet's security path just before it returns. For async crypto, this construction presents an obstacle since we may need to leave the loop after each transform. In fact, it's much easier to just skip the stack completely and always store to the security path. This is proven by the fact that this patch actually shrinks the code.

* [IPSEC]: Merge most of the input pathHerbert Xu2008-01-28
| | | | | | | | | | | | As part of the work on asynchronous cryptographic operations, we need to be able to resume from the spot where they occur. As such, it helps if we isolate them to one spot.

* [IPV6]: Add ip6_local_outHerbert Xu2008-01-28
| | | | | | | | | | | | | | Most callers of the LOCAL_OUT chain will set the IP packet length before doing so. They also share the same output function dst_output. This patch creates a new function called ip6_local_out which does all of that and converts the appropriate users over to it.

* [IPSEC]: Separate inner/outer mode processing on inputHerbert Xu2008-01-28
| | | | | | | | | | | | | | | | | | | With inter-family transforms the inner mode differs from the outer mode. Attempting to handle both sides from the same function means that it needs to handle both IPv4 and IPv6 which creates duplication and confusion. This patch separates the two parts on the input path so that each function deals with one family only. In particular, the functions xfrm4_extract_inut/xfrm6_extract_inut moves the pertinent fields from the IPv4/IPv6 IP headers into a neutral format stored in skb->cb. This is then used by the inner mode input functions to modify the inner IP header. In this way the input function no longer has to know about the outer address family.

Since the extract functions are only called by tunnel modes (the only modes that can support inter-family transforms), I've also moved the xfrm*_tunnel_check_size calls into them. This allows the correct ICMP message to be sent as opposed to now where you might call icmp_send with an IPv6 packet and vice versa.

* [INET]: Give outer DSCP directly to ip*_copy_dscpHerbert Xu2008-01-28
| | | | | | | | | This patch changes the prototype of ipv4_copy_dscp and ipv6_copy_dscp so that they directly take the outer DSCP rather than the outer IP header.

* [IPSEC]: Move x->outer_mode->output out of locked sectionHerbert Xu2008-01-28
| | | | | | | | | | | | | RO mode is the only one that requires a locked output function. So it's easier to move the lock into that function rather than requiring everyone else to run under the lock. In particular, this allows us to move the size check into the output function without causing a potential dead-lock should the ICMP error somehow hit the same SA on transmission.

* [IPSEC]: Forbid BEET + ipcomp for nowHerbert Xu2008-01-28
| | | | | | | | | | | | | | | | 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. This patch simply fails such constructions for now. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPSEC]: Merge common code into xfrm_bundle_createHerbert Xu2008-01-28
| | | | | | | | | | | | | | | | Half of the code in xfrm4_bundle_create and xfrm6_bundle_create are common. This patch extracts that logic and puts it into xfrm_bundle_create. The rest of it are then accessed through afinfo. As a result this fixes the problem with inter-family transforms where we treat every xfrm dst in the bundle as if it belongs to the top family. This patch also fixes a long-standing error-path bug where we may free the xfrm states twice. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

* [IPSEC]: Move flow construction into xfrm_dst_lookupHerbert Xu2008-01-28
| | | | | | | | | | | | | | This patch moves the flow construction from the callers of xfrm_dst_lookup into that function. It also changes xfrm_dst_lookup so that it takes an xfrm state as its argument instead of explicit addresses. This removes any address-specific logic from the callers of xfrm_dst_lookup which is needed to correctly support inter-family transforms.

* [IPSEC]: Replace x->type->{local,remote}_addr with flagsHerbert Xu2008-01-28
| | | | | | | | | | The functions local_addr and remote_addr are more than what they're needed for. The same thing can be done easily with flags on the type object.

* [IPSEC]: Make sure idev is consistent with dev in xfrm_dstHerbert Xu2008-01-28
| | | | | | | | | | | | | | | | | | | Previously we took the device from the bottom route and idev from the top route. This is bad because idev may well point to a different device. This patch changes it so that we get the idev from the device directly. It also makes it an error if either dev or idev is NULL. This is consistent with the rest of the routing code which also treats these cases as errors. I've removed the err initialisation in xfrm6_policy.c because it achieves no purpose and hid a bug when an initial version of this patch neglected to set err to -ENODEV (fortunately the IPv4 version warned about it).

* [IPSEC]: Set dst->input to dst_discardHerbert Xu2008-01-28
| | | | | | | | | The input function should never be invoked on IPsec dst objects. This is because we don't apply IPsec on input until after we've made the routing decision. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPSEC]: Only set neighbour on top xfrm dstHerbert Xu2008-01-28
| | | | | | | | | | The neighbour field is only used by dst_confirm which only ever happens on the top-most xfrm dst. So it's a waste to duplicate for every other xfrm dst.

* [NET]: Remove unnecessary inclusion of dst.hHerbert Xu2008-01-28

* [NET]: Eliminate duplicate copies of dst_discardHerbert Xu2008-01-28
| | | | | | | | | | | | | | | | | | | | | We have a number of copies of dst_discard scattered around the place which all do the same thing, namely free a packet on the input or output paths. This patch deletes all of them except dst_discard and points all the users to it. The only non-trivial bit is decnet where it returns an error. However, conceptually this is identical to the blackhole functions used in IPv4 and IPv6 which do not return errors. So they should either all return errors or all return zero. For now I've stuck with the majority and picked zero as the return value. It doesn't really matter in practice since few if any driver would react differently depending on a zero return value or NET_RX_DROP.

* [IPV6]: Move nfheader_len into rt6_infoHerbert Xu2008-01-28
| | | | | | | | | | | The dst member nfheader_len is only used by IPv6. It's also currently creating a rather ugly alignment hole in struct dst. Therefore this patch moves it from there into struct rt6_info. It also reorders the fields in rt6_info to minimize holes.

* [IPSEC]: Use dst->header_len when resizing on outputHerbert Xu2008-01-28
| | | | | | | | | Currently we use x->props.header_len when resizing on output. However, if we're resizing at all we might as well go the whole hog and do it for the whole dst. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPV6]: Only set nfheader_len for top xfrm dstHerbert Xu2008-01-28
| | | | | | | | | | | | We only need to set nfheader_len in the top xfrm dst. This is because we only ever read the nfheader_len from the top xfrm dst. It is also easier to count nfheader_len as part of header_len which then lets us remove the ugly wrapper functions for incrementing and decrementing header lengths in xfrm6_policy.c.

The pci interrupts and the push switch all work well with and without this patch. CF and AX88796 are not ok though and the source of the problem is unknown at this point. The AX88796 does for not detect it's proper mac address (IPL gets it right) and the kernel hangs on CF access.
