* IPVS: make FTP work with full NAT supportHannes Eder2010-07-235-59/+165
| | | | | | | | | | | | | | | | | | | | | | | | Use nf_conntrack/nf_nat code to do the packet mangling and the TCP sequence adjusting. The function 'ip_vs_skb_replace' is now dead code, so it is removed. To SNAT FTP, use something like: % iptables -t nat -A POSTROUTING -m ipvs --vaddr 192.168.100.30/32 \ --vport 21 -j SNAT --to-source 192.168.10.10 and for the data connections in passive mode: % iptables -t nat -A POSTROUTING -m ipvs --vaddr 192.168.100.30/32 \ --vportctl 21 -j SNAT --to-source 192.168.10.10 using '-m state --state RELATED' would also works. Make sure the kernel modules ip_vs_ftp, nf_conntrack_ftp, and nf_nat_ftp are loaded.

* IPVS: make friends with nf_conntrackHannes Eder2010-07-233-37/+30
| | | | | | | | | | | | | | | Update the nf_conntrack tuple in reply direction, as we will see traffic from the real server (RIP) to the client (CIP). Once this is done we can use netfilters SNAT in POSTROUTING, especially with xt_ipvs, to do source NAT, e.g.: % iptables -t nat -A POSTROUTING -m ipvs --vaddr 192.168.100.30/32 --vport 80 \ -j SNAT --to-source 192.168.10.10 [ minor fixes by Simon Horman <horms@verge.net.au> ] Signed-off-by: Hannes Eder <heder@google.com> Signed-off-by: Simon Horman <horms@verge.net.au> Signed-off-by: Patrick McHardy <kaber@trash.net>

* netfilter: add CHECKSUM targetMichael S. Tsirkin2010-07-154-0/+105
| | | | | | | | | | | | | | | | | | | | | | | | This adds a `CHECKSUM' target, which can be used in the iptables mangle table. You can use this target to compute and fill in the checksum in a packet that lacks a checksum. This is particularly useful, if you need to work around old applications such as dhcp clients, that do not work well with checksum offloads, but don't want to disable checksum offload in your device. The problem happens in the field with virtualized applications. For reference, see Red Hat bz 605555, as well as http://www.spinics.net/lists/kvm/msg37660.html Typical expected use (helps old dhclient binary running in a VM): iptables -A POSTROUTING -t mangle -p udp --dport bootpc \ -j CHECKSUM --checksum-fill Includes fixes by Jan Engelhardt <jengelh@medozas.de> Signed-off-by: Michael S.

* netfilter: nf_ct_tcp: fix flow recovery with TCP window tracking enabledPablo Neira Ayuso2010-07-151-1/+9
| | | | | | | | | | | | | | | | | | | | This patch adds the missing bits to support the recovery of TCP flows without disabling window tracking (aka be_liberal). To ensure a successful recovery, we have to inject the window scale factor via ctnetlink. This patch has been tested with a development snapshot of conntrackd and the new clause `TCPWindowTracking' that allows to perform strict TCP window tracking recovery across fail-overs. With this patch, we don't update the receiver's window until it's not initiated. We require this to perform a successful recovery. Jozsef confirmed in a private email that this spotted a real issue since that should not happen.

* nfnetlink_log: do not expose NFULNL_COPY_DISABLED to user-spacePablo Neira Ayuso2010-07-152-1/+3
| | | | | | | | | | | | | | | | | | | | | This patch moves NFULNL_COPY_PACKET definition from linux/netfilter/nfnetlink_log.h to net/netfilter/nfnetlink_log.h since this copy mode is only for internal use. I have also changed the value from 0x03 to 0xff. Thus, we avoid a gap from user-space that may confuse users if we add new copy modes in the future. This change was introduced in: http://www.spinics.net/lists/netfilter-devel/msg13535.html Since this change is not included in any stable Linux kernel, I think it's safe to make this change now. Anyway, this copy mode does not make any sense from user-space, so this patch should not break any existing setup.

Packets are looped through veth devices, during which they are NATed to private addresses, after which they can continue normally through the stack and possibly have NAT rules applied a second time. This works well, but is needlessly complicated for cases where only a single SNAT/DNAT mapping needs to be applied to these packets. In that case, all that needs to be done is to assign each network to a seperate zone and perform NAT as usual. However this doesn't work for packets destined for the machine performing NAT itself since its corrently not possible to configure SNAT mappings for the LOCAL_IN chain. This patch adds a new INPUT chain to the NAT table and changes the targets performing SNAT to be usable in that chain. Example usage with two identical networks (192.168.0.0/24) on eth0/eth1: iptables -t raw -A PREROUTING -i eth0 -j CT --zone 1 iptables -t raw -A PREROUTING -i eth0 -j MARK --set-mark 1 iptables -t raw -A PREROUTING -i eth1 -j CT --zone 2 iptabels -t raw -A PREROUTING -i eth1 -j MARK --set-mark 2 iptables -t nat -A INPUT -m mark --mark 1 -j NETMAP --to 10.0.0.0/24 iptables -t nat -A POSTROUTING -m mark --mark 1 -j NETMAP --to 10.0.0.0/24 iptables -t nat -A INPUT -m mark --mark 2 -j NETMAP --to 10.0.1.0/24 iptables -t nat -A POSTROUTING -m mark --mark 2 -j NETMAP --to 10.0.1.0/24 iptables -t raw -A PREROUTING -d 10.0.0.0/24 -j CT --zone 1 iptables -t raw -A OUTPUT -d 10.0.0.0/24 -j CT --zone 1 iptables -t raw -A PREROUTING -d 10.0.1.0/24 -j CT --zone 2 iptables -t raw -A OUTPUT -d 10.0.1.0/24 -j CT --zone 2 iptables -t nat -A PREROUTING -d 10.0.0.0/24 -j NETMAP --to 192.168.0.0/24 iptables -t nat -A OUTPUT -d 10.0.0.0/24 -j NETMAP --to 192.168.0.0/24 iptables -t nat -A PREROUTING -d 10.0.1.0/24 -j NETMAP --to 192.168.0.0/24 iptables -t nat -A OUTPUT -d 10.0.1.0/24 -j NETMAP --to 192.168.0.0/24 Signed-off-by: Patrick McHardy <kaber@trash.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 82576 expects the second rx queue in any pool to receive L2 switch loop back packets sent from the second tx queue in another pool. The 82576 VF driver does not enable the second rx queue so if the PF driver sends packets destined to a VF from its second tx queue then the VF driver will never see them. In SR-IOV mode limit the number of tx queues used by the PF driver to one. This patch fixes a bug reported in which the PF cannot communciate with the VF and should be considered for 2.6.34 stable.

| | | | | | | | | | | | | | | | | | | | Since ehea_get_stats calls ehea_h_query_ehea_port, which can sleep, we can also sleep when allocating a page in this function. This fixes some memory allocation failure warnings seen under low memory conditions. Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow selection of minstrel_ht as default rate control algorithm. At the moment minstrel_ht can only be requested by the driver code but not selected as default in make menuconfig. Fix this by using minstrel_ht when minstrel was selected as default and minstrel_ht is available. This change won't affect legacy devices as minstrel_ht falls back to minstrel in that case.

| * | ath9k: fix TSF after reset on AR913xFelix Fietkau2010-06-301-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When issuing a reset, the TSF value is lost in the hardware because of the 913x specific cold reset. As with some AR9280 cards, the TSF needs to be preserved in software here. Additionally, there's an issue that frequently prevents a successful TSF write directly after the chip reset. In this case, repeating the TSF write after the initval-writes usually works. This patch detects failed TSF writes and recovers from them, taking into account the delay caused by the initval writes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Latest rt2870 legacy driver also sets BBP_CSR_CFG_BBP_RW_MODE to 1 when reading or writing the EEPROM. This means we can make the BBP reading and writing completely equal on all platforms. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Legacy driver indicates that BBP1_TX_ANTENNA must be set to 0 for TXPATH values of 1 and 3. So the previous statement that nothing should be done for TXPATH = 3, is false. Furthermore, remove the false BBP3_RX_ANTENNA initialization when TXPATH is 1 for PCI and SOC devices. This field will always be overridden in the next switch statement, making this initialization bogus. History of this line indicates it was there from the beginning, and was once caught as typo. Instead of replacing the line with the correct line, the correct line was added...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | IEEE80211_HT_CAP_RX_STBC is a 2 bit flag, and should thus never be set as normal flag. Instead we must read the number of RX paths from the EEPROM and set the IEEE80211_HT_CAP_RX_STBC with the correct value (using the same logic as the number of TX streams).
