I was asked about "why don't we perform a sk_net filtering in bind_conflict calls, like we do in other sock lookup places" for a couple of times. Can we please add a comment about why we do not need one? Signed-off-by: NPavel Emelyanov <xemul@openvz.org> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

These sockets now have a bit other names and are no longer global. Shame on me, I haven't provided a good comment for this when sending DCCP netnsization patches. Signed-off-by: NPavel Emelyanov <xemul@openvz.org> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Invalid states can cause out-of-bound memory accesses of the state table. Also don't insist on having a new state contained in the netlink message. Signed-off-by: NPatrick McHardy <kaber@trash.net>

Connection tracking helpers (specifically FTP) need to be called before NAT sequence numbers adjustments are performed to be able to compare them against previously seen ones. We've introduced two new hooks around 2.6.11 to maintain this ordering when NAT modules were changed to get called from conntrack helpers directly. The cost of netfilter hooks is quite high and sequence number adjustments are only rarely needed however. Add a RCU-protected sequence number adjustment function pointer and call it from IPv4 conntrack after calling the helper. Signed-off-by: NPatrick McHardy <kaber@trash.net>

New extensions may only be added to unconfirmed conntracks to avoid races when reallocating the storage. Also change NF_CT_ASSERT to use WARN_ON to get backtraces. Signed-off-by: NPatrick McHardy <kaber@trash.net>

Adding extensions to confirmed conntracks is not allowed to avoid races on reallocation. Don't setup NAT for confirmed conntracks in case NAT module is loaded late. The has one side-effect, the connections existing before the NAT module was loaded won't enter the bysource hash. The only case where this actually makes a difference is in case of SNAT to a multirange where the IP before NAT is also part of the range. Since old connections don't enter the bysource hash the first new connection from the IP will have a new address selected. This shouldn't matter at all.

Locally generated ICMP packets have a reference to the conntrack entry of the original packet manually attached by icmp_send(). Therefore the check for locally originated untracked ICMP redirects can never be true. Signed-off-by: NPatrick McHardy <kaber@trash.net>

Move the UDP-Lite conntrack checksum validation to a generic helper similar to nf_checksum() and make it fall back to nf_checksum() in case the full packet is to be checksummed and hardware checksums are available. This is to be used by DCCP conntrack, which also needs to verify partial checksums. Signed-off-by: NPatrick McHardy <kaber@trash.net>

Rule dumping is performed in two steps: first userspace gets the ruleset size using getsockopt(SO_GET_INFO) and allocates memory, then it calls getsockopt(SO_GET_ENTRIES) to actually dump the ruleset. When another process changes the ruleset in between the sizes from the first getsockopt call doesn't match anymore and the kernel aborts. Unfortunately it returns EAGAIN, as for multiple other possible errors, so userspace can't distinguish this case from real errors. Return EAGAIN so userspace can retry the operation. Fixes (with current iptables SVN version) netfilter bugzilla #104. Signed-off-by: NPatrick McHardy <kaber@trash.net>
