Section 9.23.3.5 of IEEE 80211s standard describes the protection rules for HT mesh STA in a MBSS. Three HT protection modes are supported for now: non-HT mixed mode - is selected if any non-HT peers are present in our MBSS. 20MHz-protection mode - is selected if all peers in our 20/40MHz MBSS support HT and atleast one HT20 peer is present. no-protection mode - is selected otherwise.

2012-05-08netfilter: nf_conntrack: fix explicit helper attachment and NATPablo Neira Ayuso1-1/+12
Explicit helper attachment via the CT target is broken with NAT if non-standard ports are used. This problem was hidden behind the automatic helper assignment routine. Thus, it becomes more noticeable now that we can disable the automatic helper assignment with Eric Leblond's: 9e8ac5a netfilter: nf_ct_helper: allow to disable automatic helper assignment Basically, nf_conntrack_alter_reply asks for looking up the helper up if NAT is enabled. Unfortunately, we don't have the conntrack template at that point anymore. Since we don't want to rely on the automatic helper assignment, we can skip the second look-up and stick to the helper that was attached by iptables. With the CT target, the user is in full control of helper attachment, thus, the policy is to trust what the user explicitly configures via iptables (no automatic magic anymore). Interestingly, this bug was hidden by the automatic helper look-up code. But it can be easily trigger if you attach the helper in a non-standard port, eg. iptables -I PREROUTING -t raw -p tcp --dport 8888 \ -j CT --helper ftp And you disabled the automatic helper assignment. I added the IPS_HELPER_BIT that allows us to differenciate between a helper that has been explicitly attached and those that have been automatically assigned. I didn't come up with a better solution (having backward compatibility in mind). Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2012-05-08netfilter: nf_ct_expect: partially implement ctnetlink_change_expectKelvie Wong1-1/+9
This refreshes the "timeout" attribute in existing expectations if one is given. The use case for this would be for userspace helpers to extend the lifetime of the expectation when requested, as this is not possible right now without deleting/recreating the expectation. I use this specifically for forwarding DCERPC traffic through: DCERPC has a port mapper daemon that chooses a (seemingly) random port for future traffic to go to. We expect this traffic (with a reasonable timeout), but sometimes the port mapper will tell the client to continue using the same port. This allows us to extend the expectation accordingly.

2012-05-08ipvs: add support for sync threadsPablo Neira Ayuso3-157/+280
Allow master and backup servers to use many threads for sync traffic. Add sysctl var "sync_ports" to define the number of threads. Every thread will use single UDP port, thread 0 will use the default port 8848 while last thread will use port 8848+sync_ports-1. The sync traffic for connections is scheduled to many master threads based on the cp address but one connection is always assigned to same thread to avoid reordering of the sync messages. Remove ip_vs_sync_switch_mode because this check for sync mode change is still risky. Instead, check for mode change under sync_buff_lock. Make sure the backup socks do not block on reading.

2012-05-08ipvs: reduce sync rate with time thresholdsJulian Anastasov4-46/+137
Add two new sysctl vars to control the sync rate with the main idea to reduce the rate for connection templates because currently it depends on the packet rate for controlled connections. This mechanism should be useful also for normal connections with high traffic. sync_refresh_period: in seconds, difference in reported connection timer that triggers new sync message. It can be used to avoid sync messages for the specified period (or half of the connection timeout if it is lower) if connection state is not changed from last sync. sync_retries: integer, 0..3, defines sync retries with period of sync_refresh_period/8. Useful to protect against loss of sync messages. Allow sysctl_sync_threshold to be used with sysctl_sync_period=0, so that only single sync message is sent if sync_refresh_period is also 0. Add new field "sync_endtime" in connection structure to hold the reported time when connection expires. The 2 lowest bits will represent the retry count. As the sysctl_sync_period now can be 0 use ACCESS_ONCE to avoid division by zero. Special thanks to Aleksey Chudov for being patient with me, for his extensive reports and helping in all tests.

2012-05-08ipvs: wakeup master threadPablo Neira Ayuso2-32/+133
High rate of sync messages in master can lead to overflowing the socket buffer and dropping the messages. Fixed sleep of 1 second without wakeup events is not suitable for loaded masters, Use delayed_work to schedule sending for queued messages and limit the delay to IPVS_SYNC_SEND_DELAY (20ms). This will reduce the rate of wakeups but to avoid sending long bursts we wakeup the master thread after IPVS_SYNC_WAKEUP_RATE (8) messages. Add hard limit for the queued messages before sending by using "sync_qlen_max" sysctl var. It defaults to 1/32 of the memory pages but actually represents number of messages. It will protect us from allocating large parts of memory when the sending rate is lower than the queuing rate. As suggested by Pablo, add new sysctl var "sync_sock_size" to configure the SNDBUF (master) or RCVBUF (slave) socket limit. Default value is 0 (preserve system defaults). Change the master thread to detect and block on SNDBUF overflow, so that we do not drop messages when the socket limit is low but the sync_qlen_max limit is not reached. On ENOBUFS or other errors just drop the messages. Change master thread to enter TASK_INTERRUPTIBLE state early, so that we do not miss wakeups due to messages or kthread_should_stop event.

2012-05-08netfilter: bridge: optionally set indev to vlanPablo Neira Ayuso1-2/+24
if net.bridge.bridge-nf-filter-vlan-tagged sysctl is enabled, bridge netfilter removes the vlan header temporarily and then feeds the packet to ip(6)tables. When the new "bridge-nf-pass-vlan-input-device" sysctl is on (default off), then bridge netfilter will also set the in-interface to the vlan interface; if such an interface exists. This is needed to make iptables REDIRECT target work with "vlan-on-top-of-bridge" setups and to allow use of "iptables -i" to match the vlan device name. Also update Documentation with current brnf default settings.

2012-05-08netfilter: nf_ct_helper: allow to disable automatic helper assignmentEric Leblond2-19/+105
This patch allows you to disable automatic conntrack helper lookup based on TCP/UDP ports, eg. echo 0 > /proc/sys/net/netfilter/nf_conntrack_helper [ Note: flows that already got a helper will keep using it even if automatic helper assignment has been disabled ] Once this behaviour has been disabled, you have to explicitly use the iptables CT target to attach helper to flows. There are good reasons to stop supporting automatic helper assignment, for further information, please read: http://www.netfilter.org/news.html#2012-04-03 This patch also adds one message to inform that automatic helper assignment is deprecated and it will be removed soon (this is spotted only once, with the first flow that gets a helper attached to make it as less annoying as possible).

In 'net' we added a bug fix to make iwlwifi report a more accurate skb->truesize but this conflicted with RX path changes that happened meanwhile in net-next. In e1000e a conflict arose in the validation code for settings of adapter->itr. 'net-next' had more sophisticated logic so that logic was used. Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-08net: IP_MULTICAST_IF setsockopt now recognizes struct mreqJiri Pirko1-4/+9
Until now, struct mreq has not been recognized and it was worked with as with struct in_addr. That means imr_multiaddr was copied to imr_address. So do recognize struct mreq here and copy that correctly. Signed-off-by: Jiri Pirko <jpirko@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-06skb: Add inline helper for getting the skb end offset from headAlexander Duyck1-6/+6
With the recent changes for how we compute the skb truesize it occurs to me we are probably going to have a lot of calls to skb_end_pointer - skb->head. Instead of running all over the place doing that it would make more sense to just make it a separate inline skb_end_offset(skb) that way we can return the correct value without having gcc having to do all the optimization to cancel out skb->head - skb->head.

2012-05-06skb: Drop "fastpath" variable for skb_cloned check in pskb_expand_headAlexander Duyck1-14/+8
Since there is now only one spot that actually uses "fastpath" there isn't much point in carrying it. Instead we can just use a check for skb_cloned to verify if we can perform the fast-path free for the head or not.
