* ipv6: Plug sk_buff leak in ipv6_rcv (net/ipv6/ip6_input.c)Jesper Nilsson2009-03-27
| | | | | | | | | | | | | | | | | | | | | Commit 778d80be52699596bf70e0eb0761cf5e1e46088d (ipv6: Add disable_ipv6 sysctl to disable IPv6 operaion on specific interface) seems to have introduced a leak of sk_buff's for ipv6 traffic, at least in some configurations where idev is NULL, or when ipv6 is disabled via sysctl. The problem is that if the first condition of the if-statement returns non-NULL, it returns an skb with only one reference, and when the other conditions apply, execution jumps to the "out" label, which does not call kfree_skb for it. To plug this leak, change to use the "drop" label instead. (this relies on it being ok to call kfree_skb on NULL) This also allows us to avoid calling rcu_read_unlock here, and removes the only user of the "out" label.

* net: Add support for the OpenCores 10/100 Mbps Ethernet MAC.Thierry Reding2009-03-27
| | | | | | | | | | | | | | This patch adds a platform device driver that supports the OpenCores 10/100 Mbps Ethernet MAC. The driver expects three resources: one IORESOURCE_MEM resource defines the memory region for the core's memory-mapped registers while a second IORESOURCE_MEM resource defines the network packet buffer space. The third resource, of type IORESOURCE_IRQ, associates an interrupt with the driver.

| * ctnetlink: compute generic part of event more acuratelyHolger Eitzenberger2009-03-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | On a box with most of the optional Netfilter switches turned off some of the NLAs are never send, e. g. secmark, mark or the conntrack byte/packet counters. As a worst case scenario this may possibly still lead to ctnetlink skbs being reallocated in netlink_trim() later, loosing all the nice effects from the previous patches. I try to solve that (at least partly) by correctly #ifdef'ing the NLAs in the computation.

| * netfilter: ctnetlink: allocate right-sized ctnetlink skbHolger Eitzenberger2009-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Try to allocate a Netlink skb roughly the size of the actual message, with the help from the l3 and l4 protocol helpers. This is all to prevent a reallocation in netlink_trim() later. The overhead of allocating the right-sized skb is rather small, with ctnetlink_alloc_skb() actually being inlined away on my x86_64 box. The size of the per-proto space is determined at registration time of the protocol helper.

| * netfilter: nf_conntrack: use SLAB_DESTROY_BY_RCU and get rid of call_rcu()Eric Dumazet2009-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use "hlist_nulls" infrastructure we added in 2.6.29 for RCUification of UDP & TCP. This permits an easy conversion from call_rcu() based hash lists to a SLAB_DESTROY_BY_RCU one. Avoiding call_rcu() delay at nf_conn freeing time has numerous gains. First, it doesnt fill RCU queues (up to 10000 elements per cpu). This reduces OOM possibility, if queued elements are not taken into account This reduces latency problems when RCU queue size hits hilimit and triggers emergency mode. - It allows fast reuse of just freed elements, permitting better use of CPU cache. - We delete rcu_head from "struct nf_conn", shrinking size of this structure by 8 or 16 bytes. This patch only takes care of "struct nf_conn". call_rcu() is still used for less critical conntrack parts, that may be converted later if necessary.

| * netfilter: {ip,ip6,arp}_tables: fix incorrect loop detectionPatrick McHardy2009-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit e1b4b9f ([NETFILTER]: {ip,ip6,arp}_tables: fix exponential worst-case search for loops) introduced a regression in the loop detection algorithm, causing sporadic incorrectly detected loops. When a chain has already been visited during the check, it is treated as having a standard target containing a RETURN verdict directly at the beginning in order to not check it again. The real target of the first rule is then incorrectly treated as STANDARD target and checked not to contain invalid verdicts. Fix by making sure the rule does actually contain a standard target.

| * netfilter: ctnetlink: add callbacks to the per-proto nlattrsHolger Eitzenberger2009-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is added a single callback for the l3 proto helper. The two callbacks for the l4 protos are necessary because of the general structure of a ctnetlink event, which is in short: CTA_TUPLE_ORIG <l3/l4-proto-attributes> CTA_TUPLE_REPLY <l3/l4-proto-attributes> CTA_ID ... CTA_PROTOINFO <l4-proto-attributes> CTA_TUPLE_MASTER <l3/l4-proto-attributes> Therefore the formular is size := sizeof(generic-nlas) + 3 * sizeof(tuple_nlas) + sizeof(protoinfo_nlas) Some of the NLAs are optional, e. g. CTA_TUPLE_MASTER, which is only set if it's an expected connection. But the number of optional NLAs is small enough to prevent netlink_trim() from reallocating if calculated properly.
