2006-01-14x86: Work around compiler code generation bug with -OsLinus Torvalds
Some versions of gcc generate incorrect code for the inet_check_attr() function, apparently due to a totally bogus index -> pointer comparison transformation. At least "gcc version 4.0.1 20050727 (Red Hat 4.0.1-5)" from FC4 is affected, possibly others too. This changes the function subtly so that the buggy gcc transformation doesn't trigger.

2006-01-13[XFRM]: IPsec tunnel wildcard address supportPatrick McHardy
When the source address of a tunnel is given as 0.0.0.0 do a routing lookup to get the real source address for the destination and fill that into the acquire message. This allows to specify policies like this: spdadd 172.16.128.13/32 172.16.0.0/20 any -P out ipsec esp/tunnel/0.0.0.0-x.x.x.x/require; spdadd 172.16.0.0/20 172.16.128.13/32 any -P in ipsec esp/tunnel/x.x.x.x-0.0.0.0/require; Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2006-01-12[NETFILTER] x_tables: Abstraction layer for {ip,ip6,arp}_tablesHarald Welte
This monster-patch tries to do the best job for unifying the data structures and backend interfaces for the three evil clones ip_tables, ip6_tables and arp_tables. In an ideal world we would never have allowed this kind of copy+paste programming... but well, our world isn't (yet?) ideal. o introduce a new x_tables module o {ip,arp,ip6}_tables depend on this x_tables module o registration functions for tables, matches and targets are only wrappers around x_tables provided functions o all matches/targets that are used from ip_tables and ip6_tables are now implemented as xt_FOOBAR.c files and provide module aliases to ipt_FOOBAR and ip6t_FOOBAR o header files for xt_matches are in include/linux/netfilter/, include/linux/netfilter_{ipv4,ipv6} contains compatibility wrappers around the xt_FOOBAR.h headers Based on this patchset we're going to further unify the code, gradually getting rid of all the layer 3 specific assumptions.

2006-01-10[NETFILTER]: Fix timeout sysctls on big-endian 64bit architecturesPatrick McHardy

2006-01-10[NETFILTER]: Fix another crash in ip_nat_pptpPatrick McHardy
The PPTP NAT helper calculates the offset at which the packet needs to be mangled as difference between two pointers to the header. With non-linear skbs however the pointers may point to two seperate buffers on the stack and the calculation results in a wrong offset beeing used.

2006-01-10[NETFILTER]: Fix crash in ip_nat_pptpPatrick McHardy
When an inbound PPTP_IN_CALL_REQUEST packet is received the PPTP NAT helper uses a NULL pointer in pointer arithmentic to calculate the offset in the packet which needs to be mangled and corrupts random memory or crashes.

2006-01-07[NETFILTER]: Keep conntrack reference until IPsec policy checks are donePatrick McHardy
Keep the conntrack reference until policy checks have been performed for IPsec NAT support.

Miller <davem@davemloft.net>
2006-01-07[NETFILTER]: Redo policy lookups after NAT when neccessaryPatrick McHardy
When NAT changes the key used for the xfrm lookup it needs to be done again. If a new policy is returned in POST_ROUTING the packet needs to be passed to xfrm4_output_one manually after all hooks were called because POST_ROUTING is called with fixed okfn (ip_finish_output).

2006-01-07[NETFILTER]: Use conntrack information to determine if packet was NATedPatrick McHardy

2006-01-07[NETFILTER]: Fix xfrm lookup in ip_route_me_harder/ip6_route_me_harderPatrick McHardy
ip_route_me_harder doesn't use the port numbers of the xfrm lookup and uses ip_route_input for non-local addresses which doesn't do a xfrm lookup, ip6_route_me_harder doesn't do a xfrm lookup at all. Use xfrm_decode_session and do the lookup manually, make sure both only do the lookup if the packet hasn't been transformed already. Makeing sure the lookup only happens once needs a new field in the IP6CB, which exceeds the size of skb->cb. The size of skb->cb is increased to 48b. Apparently the IPv6 mobile extensions need some more room anyway. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-01-07[IPV4]: reset IPCB flags when neccessaryPatrick McHardy
Reset IPSKB_XFRM_TUNNEL_SIZE flags in ipip and ip_gre hard_start_xmit function before the packet reenters IP. This is neccessary so the encapsulated packets are checked not to be oversized in xfrm4_output.c again. Reset all flags in sit when a packet changes its address family. Also remove some obsolete IPSKB flags. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-01-07[IPV4/6]: Netfilter IPsec input hooksPatrick McHardy
When the innermost transform uses transport mode the decapsulated packet is not visible to netfilter. Pass the packet through the PRE_ROUTING and LOCAL_IN hooks again before handing it to upper layer protocols to make netfilter-visibility symetrical to the output path.

2006-01-07[XFRM]: Netfilter IPsec output hooksPatrick McHardy
Call netfilter hooks before IPsec transforms. Packets visit the FORWARD/LOCAL_OUT and POST_ROUTING hook before the first encapsulation and the LOCAL_OUT and POST_ROUTING hook before each following tunnel mode transform. Patch from Herbert Xu <herbert@gondor.apana.org.au>: Move the loop from dst_output into xfrm4_output/xfrm6_output since they're the only ones who need to it. xfrm{4,6}_output_one() processes the first SA all subsequent transport mode SAs and is called in a loop that calls the netfilter hooks between each two calls. In order to avoid the tail call issue, I've added the inline function nf_hook which is nf_hook_slow plus the empty list check. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.
