| * [NETNS]: Lookup in FIB semantic hashes taking into account the namespace.Denis V. Lunev2008-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | The namespace is not available in the fib_sync_down_addr, add it as a parameter. Looking up a device by the pointer to it is OK. Looking up using a result from fib_trie/fib_hash table lookup is also safe. No need to fix that at all. So, just fix lookup by address and insertion to the hash table path. Signed-off-by: Denis V.

| * [NETNS]: Add a namespace mark to fib_info.Denis V. Lunev2008-01-31
| | | | | | | | | | | | | | | | | | This is required to make fib_info lookups namespace aware. In the other case initial namespace devices are marked as dead in the local routing table during other namespace stop. Signed-off-by: Denis V. Lunev <den@openvz.org> Signed-off-by: David S.

| * [IPV4]: fib_sync_down rework.Denis V. Lunev2008-01-31
| | | | | | | | | | | | | | | | | | | | fib_sync_down can be called with an address and with a device. In reality it is called either with address OR with a device. The codepath inside is completely different, so lets separate it into two calls for these two cases. Signed-off-by: Denis V. Lunev <den@openvz.org> Signed-off-by: David S.

| * [NET_SCHED]: Add flow classifierPatrick McHardy2008-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new "flow" classifier, which is meant to extend the SFQ hashing capabilities without hard-coding new hash functions and also allows deterministic mappings of keys to classes, replacing some out of tree iptables patches like IPCLASSIFY (maps IPs to classes), IPMARK (maps IPs to marks, with fw filters to classes), ... Some examples: - Classic SFQ hash: tc filter add ... flow hash \ keys src,dst,proto,proto-src,proto-dst divisor 1024 - Classic SFQ hash, but using information from conntrack to work properly in combination with NAT: tc filter add ... flow hash \ keys nfct-src,nfct-dst,proto,nfct-proto-src,nfct-proto-dst divisor 1024 - Map destination IPs of 192.168.0.0/24 to classids 1-257: tc filter add ... flow map \ key dst addend -192.168.0.0 divisor 256 - alternatively: tc filter add ... flow map \ key dst and 0xff - similar, but reverse ordered: tc filter add ... flow map \ key dst and 0xff xor 0xff Perturbation is currently not supported because we can't reliable kill the timer on destruction.

| * [IPV4] route cache: Introduce rt_genid for smooth cache invalidationEric Dumazet2008-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current ip route cache implementation is not suited to large caches. We can consume a lot of CPU when cache must be invalidated, since we currently need to evict all cache entries, and this eviction is sometimes asynchronous. min_delay & max_delay can somewhat control this asynchronism behavior, but whole thing is a kludge, regularly triggering infamous soft lockup messages. When entries are still in use, this also consumes a lot of ram, filling dst_garbage.list. A better scheme is to use a generation identifier on each entry, so that cache invalidation can be performed by changing the table identifier, without having to scan all entries. No more delayed flushing, no more stalling when secret_interval expires. Invalidated entries will then be freed at GC time (controled by ip_rt_gc_timeout or stress), or when an invalidated entry is found in a chain when an insert is done. Thus we keep a normal equilibrium. This patch : - renames rt_hash_rnd to rt_genid (and makes it an atomic_t) - Adds a new rt_genid field to 'struct rtable' (filling a hole on 64bit) - Checks entry->rt_genid at appropriate places :
| * [VLAN]: set_rx_mode support for unicast address listChris Leech2008-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reuse the existing logic for multicast list synchronization for the unicast address list. The core of dev_mc_sync/unsync are split out as __dev_addr_sync/unsync and moved from dev_mcast.c to dev.c. These are then used to implement dev_unicast_sync/unsync as well. I'm working on cleaning up Intel's FCoE stack, which generates new MAC addresses from the fibre channel device id assigned by the fabric as per the current draft specification in T11. When using such a protocol in a VLAN environment it would be nice to not always be forced into promiscuous mode, assuming the underlying Ethernet driver supports multiple unicast addresses as well.

| * [IPV4] fib_trie: rescan if key is lost during dumpStephen Hemminger2008-01-31
| | | | | | | | | | | | | | | | | | | | Normally during a dump the key of the last dumped entry is used for continuation, but since lock is dropped it might be lost. In that case fallback to the old counter based N^2 behaviour. This means the dump will end up skipping some routes which matches what FIB_HASH does.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduces the xt_hashlimit match revision 1. It adds support for kernel-level inversion and grouping source and/or destination IP addresses, allowing to limit on a per-subnet basis. While this would technically obsolete xt_limit, xt_hashlimit is a more expensive due to the hashbucketing. Kernel-level inversion: Previously you had to do user-level inversion: iptables -N foo iptables -A foo -m hashlimit --hashlimit(-upto) 5/s -j RETURN iptables -A foo -j DROP iptables -A INPUT -j foo now it is simpler: iptables -A INPUT -m hashlimit --hashlimit-over 5/s -j DROP Signed-off-by: Jan Engelhardt <jengelh@computergmbh.de> Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

| * [NETFILTER]: ip_tables: per-netns FILTER, MANGLE, RAWAlexey Dobriyan2008-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now, iptables show and configure different set of rules in different netnss'. Filtering decisions are still made by consulting only init_net's set. Changes are identical except naming so no splitting. P.S.: one need to remove init_net checks in nf_sockopt.c and inet_create() to see the effect.

| * [NETFILTER]: x_tables: return new table from {arp,ip,ip6}t_register_table()Alexey Dobriyan2008-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Typical table module registers xt_table structure (i.e. packet_filter) and link it to list during it. We can't use one template for it because corresponding list_head will become corrupted. We also can't unregister with template because it wasn't changed at all and thus doesn't know in which list it is. So, we duplicate template at the very first step of table registration. Table modules will save it for use during unregistration time and actual filtering. Do it at once to not screw bisection. P.S.: renaming i.e. packet_filter => __packet_filter is temporary until full netnsization of table modules is done.

| * [NETFILTER]: x_tables: per-netns xt_tablesAlexey Dobriyan2008-01-31
| | | | | | | | | | | | | | | | | | | | | | | | In fact all we want is per-netns set of rules, however doing that will unnecessary complicate routines such as ipt_hook()/ipt_do_table, so make full xt_table array per-netns. Every user stubbed with init_net for a while. Signed-off-by: Alexey Dobriyan <adobriyan@sw.ru> Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

| * [NETFILTER]: bridge netfilter: remove nf_bridge_info read-only netoutdev memberPatrick McHardy2008-01-31
| | | | | | | | | | | | | | | | | | | | | | Before the removal of the deferred output hooks, netoutdev was used in case of VLANs on top of a bridge to store the VLAN device, so the deferred hooks would see the correct output device. This isn't necessary anymore since we're calling the output hooks for the correct device directly in the IP stack. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

| * [RAW]: Wrong content of the /proc/net/raw6.Denis V. Lunev2008-01-31
| | | | | | | | | | | | | | | | | | | | | | | | The address of IPv6 raw sockets was shown in the wrong format, from IPv4 ones. The problem has been introduced by the commit 42a73808ed4f30b739eb52bcbb33a02fe62ceef5 ("[RAW]: Consolidate proc interface.") Thanks to Adrian Bunk who originally noticed the problem.
