2014-01-12batman-adv: consider outgoing interface in OGM sendingSimon Wunderlich
The current OGM sending an aggregation functionality decides on which interfaces a packet should be sent when it parses the forward packet struct. However, with the network wide multi interface optimization the outgoing interface is decided by the OGM processing function. This is reflected by moving the decision in the OGM processing function and add the outgoing interface in the forwarding packet struct. This practically implies that an OGM may be added multiple times (once per outgoing interface), and this also affects aggregation which needs to consider the outgoing interface as well.

2014-01-12batman-adv: add WiFi penaltySimon Wunderlich
If the same interface is used for sending and receiving, there might be throughput degradation on half-duplex interfaces such as WiFi. Add a penalty if the same interface is used to reflect this problem in the metric. At the same time, change the hop penalty from 30 to 15 so there will be no change for single wifi mesh network. the effective hop penalty will stay at 30 due to the new wifi penalty for these networks.

2014-01-12batman-adv: split out router from orig_nodeSimon Wunderlich
For the network wide multi interface optimization there are different routers for each outgoing interface (outgoing from the OGM perspective, incoming for payload traffic). To reflect this, change the router and associated data to a list of routers. While at it, rename batadv_orig_node_get_router() to batadv_orig_router_get() to follow the new naming scheme.

2014-01-12batman-adv: split tq information in neigh_node structSimon Wunderlich
For the network wide multi interface optimization it is required to save metrics per outgoing interface in one neighbor. Therefore a new type is introduced to keep interface-specific information. This also requires some changes in access and list management. The compare and equiv_or_better API calls are changed to take the outgoing interface into consideration.

Most notable is Jacob's patch to add PTP support to i40e. Mitch cleans up additional memcpy's and use struct assignment instead. Then fixes long lines to appease checkpatch.pl. Mitch then provides a fix to keep us from spamming the log with confusing errors. If you use ip to change the MAC address of a VF while the VF driver is loaded, closing the VF interface or unloading the VF driver will cause the VF driver to remove the MAC filter for its original (now invalid) MAC address. Jesse cleans up macros which are no longer needed or used. I (Jeff) cleanup function header comments to ensure Doxygen/kdoc works correctly to generate documentation without warnings. Anjali fixes a bug where ethtool set-channels would return failure when configuring only one Rx queue. Then fixes a bug where the driver was erroneously exiting the driver unload path if one part of the unload failed. Shannon fixes if the IPV6EXADD but is set in the Rx descriptor status, there was an optional extension header with an alternate IP address detected and the hardware checksum was not handling the alternate IP address correctly. Then adjusts the ITR max and min values to match the hardware max value and recommended min value. Shannon makes sure to clear the PXE mode after the adminq is initialized. v2: - fix patch 14 "i40e: enable PTP" to address Richard Cochran's spelling catch and Ben Hutchings Kconfig, SIOCGHWTSTAMP and sizeof() suggestions - added Paul Gortmaker's i40evf fix patch v3: - fix patch 14 "i40e: enable PTP" to address Ben Hutchings concerns about a race with PTP init and cleanup and i40e_get_ts_info(). ==================== Signed-off-by: David S.

2014-01-10i40e: allow VF to remove any MAC filterMitch Williams
If you use ip to change the MAC address of a VF while the VF driver is loaded, closing the VF interface or unloading the VF driver will cause the VF driver to remove the MAC filter for its original (now invalid) MAC address. This would cause the PF driver to kick an error message to the log, and back to the VF driver. Since the VF driver has not really done anything naughty, let's not punish it. Don't check for MAC address overrides on the delete operation, just make sure it's a valid address. This keeps us from spamming the log with confusing errors.

2014-01-10Merge branch 'tcp_metrics_saddr'David S. Miller
Christoph Paasch says: ==================== Make tcp-metrics source-address aware Currently tcp-metrics only stores per-destination addresses. This brings problems, when a host has multiple interfaces (e.g., a smartphone having WiFi/3G): For example, a host contacting a server over WiFi will store the tcp-metrics per destination IP. If then the host contacts the same server over 3G, the same tcp-metrics will be used, although the path-characteristics are completly different (e.g., the ssthresh is probably not the same). In case of TFO this is not a problem, as the server will provide us a new cookie once he saw our SYN+DATA with an incorrect cookie. It may be (in case of carrier-grade NAT), that we keep the same public IP but have a different private IP. Thus, we better reuse the old cookie even if our source-IP has changed. However, this scenario is probably very uncommon, as carriers try to provide the same src-IP to the clients behind their CGN. Patches 1 + 2 add the source-IP to the tcp metrics. Patches 3 to 5 modify the netlink-api to support the source-IP. From now on, when using the command "ip tcp_metrics delete address ADDRESS" all entries which match this destination IP will be deleted. Today's iproute2 will complain when doing "ip tcp_metrics flush PREFIX" if several entries are present for the same destination-IP but with different source-IPs: root@client:~/test# ip tcp_metrics 10.2.1.2 age 3.640sec rtt 16250us rttvar 15000us cwnd 10 10.2.1.2 age 4.030sec rtt 18750us rttvar 15000us cwnd 10 root@client:~/test# ip tcp_metrics flush 10.2.1.2/16 Failed to send flush request : No such process Follow-up patches will modify iproute2 to handle this correctly and allow specifying the source-IP in the get/del commands. v2: Added the patch that allows to selectively get/del of tcp-metrics based on src-IP and moved the patch that adds the new netlink attribute before the other patches. ==================== Signed-off-by: David S.

2014-01-09xen-netback: stop vif thread spinning if frontend is unresponsivePaul Durrant
The recent patch to improve guest receive side flow control (ca2f09f2) had a slight flaw in the wait condition for the vif thread in that any remaining skbs in the guest receive side netback internal queue would prevent the thread from sleeping. An unresponsive frontend can lead to a permanently non-empty internal queue and thus the thread will spin. In this case the thread should really sleep until the frontend becomes responsive again. This patch adds an extra flag to the vif which is set if the shared ring is full and cleared when skbs are drained into the shared ring. Thus, if the thread runs, finds the shared ring full and can make no progress the flag remains set. If the flag remains set then the thread will sleep, regardless of a non-empty queue, until the next event from the frontend.

This also includes several patches to prepare the infrastructure for this new table and a new meta extension to match the layer 3 and 4 protocol numbers, from Patrick McHardy. * Load both IPv4 and IPv6 conntrack modules in nft_ct if the rule is used in NFPROTO_INET, as we don't certainly know which one would be used, also from Patrick McHardy. * Do not allow to delete a table that contains sets, otherwise these sets become orphan, from Patrick McHardy. * Hold a reference to the corresponding nf_tables family module when creating a table of that family type, to avoid the module deletion when in use, from Patrick McHardy. * Update chain counters before setting the chain policy to ensure that we don't leave the chain in inconsistent state in case of errors (aka. restore chain atomicity). This also fixes a possible leak if it fails to allocate the chain counters if no counters are passed to be restored, from Patrick McHardy. * Don't check for overflows in the table counter if we are just renaming a chain, from Patrick McHardy. * Replay the netlink request after dropping the nfnl lock to load the module that supports provides a chain type, from Patrick. * Fix chain type module references, from Patrick. * Several cleanups, function renames, constification and code refactorizations also from Patrick McHardy. * Add support to set the connmark, this can be used to set it based on the meta mark (similar feature to -j CONNMARK --restore), from Kristian Evensen. * A couple of fixes to the recently added meta/set support and nft_reject, and fix missing chain type unregistration if we fail to register our the family table/filter chain type, from myself. ==================== Signed-off-by: David S.

2014-01-09netfilter: introduce l2tp match extensionJames Chapman
Introduce an xtables add-on for matching L2TP packets. Supports L2TPv2 and L2TPv3 over IPv4 and IPv6. As well as filtering on L2TP tunnel-id and session-id, the filtering decision can also include the L2TP packet type (control or data), protocol version (2 or 3) and encapsulation type (UDP or IP). The most common use for this will likely be to filter L2TP data packets of individual L2TP tunnels or sessions. While a u32 match can be used, the L2TP protocol headers are such that field offsets differ depending on bits set in the header, making rules for matching generic L2TP connections cumbersome. This match extension takes care of all that. Signed-off-by: James Chapman <jchapman@katalix.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to i40e only. Anjali provides a fix where interrupts were not being re-enabled on ICR0 even though they were auto masked by hardware. Then provides a fix to cleanup RSS initialization because it was doing some extra work, so remove the extra work and any bugs it created when managing number of queues. Since hardware requires a full packet template to be pointed to when adding hardware flow filters, add the template and use it for programming filters. Jesse provides a fix to replace the use of driver specific defines with kernel ETH_ALEN defines. Then disables packet split because with the use of GRO, we do not need the extra bus overhead. Fixes spelling error in code comment. Kamil provides a fix for the driver where the hardware expects the MAC address in a very specific format and the driver was filing the data incorrectly. Mitch provides a fix to resolve a panic on reset by adding checks to VSI->rx_rings. Then shortens alloc_rx_buff_failed and alloc_rx_page_failed variables since both part of an RX specific structure so just remove the _rx part of the name. Then fixes badly formatted lines, long lines and mis-formatted lines. Shannon provides a fix to call AQ to release any reservation held by this PF on the NVM resource lock on startup, in order to clear anything that might have been left over from a previous run. Then removes interrupt on AQ error since nearly everything we do is synchronous, using the interrupt-on-error bit is unnecessary and causing unneeded interrupts. Adds code to handle the ability to send messages among the physical function interfaces by the admin queue. Catherine sets the MFP flag earlier in software init and uses that flag to decide if other hardware work-arounds are required which turns off flow director in MFP mode. ==================== Signed-off-by: David S.
