Redefine some macros that were conditioned upon SMC_DEBUG level. By allowing compiler to verify parameters used by these macros unconditionally, we can flag compilation failures. Compiler will still optimize out the unused code path depending on SMC_DEBUG, so this is a net gain. Signed-off-by:

The aggresive load balancing causes packet re-ordering as active flows are moved from a slave to another within the group. Sometime this aggresive lb is not necessary if the preference is for less re-ordering. This parameter if used with value "0" disables this dynamic flow shuffling minimizing packet re-ordering. Of course the side effect is that it has to live with the static load balancing that the hashing distribution provides. This impact is less severe if the correct xmit-hashing-policy is used for the tlb setup. The default value of the parameter is set to "1" mimicing the earlier behavior. Ran the netperf test with 200 stream for 1 min between two hosts with 4x1G trunk (xmit-lb mode with xmit-policy L3+4) before and after these changes. Following was the command used for those 200 instances - netperf -t TCP_RR -l 60 -s 5 -H <host> -- -r81920,81920 Transactions per second: Before change: 1,367.11 After change: 1,470.65 Change-Id: Ie3f75c77282cf602e83a6e833c6eb164e72a0990 Signed-off-by:Mahesh Bandewar <maheshb@google.com> Signed-off-by:

Re-organized the xmit function for the lb mode separating tlb xmit from the alb mode. This will enable use of the hashing policies like 802.3ad mode. Also extended use of xmit-hash-policy to tlb mode. Now the tlb-mode defaults to BOND_XMIT_POLICY_LAYER2 if the xmit policy module parameter is not set (just like 802.3ad, or Xor mode).

Separating the actual xmit part from the function in a separate function that can be used in the tlb_xmit in the next patch. Also there is no reason do_tx_balance to be an int so changing it to bool type. Change-Id: I9c48ff30487810f68587e621a191db616f49bd3b Signed-off-by:

Modified the hash function to return just hash separating from the modulo operation that can be performed by the caller. This is to make way for the tlb mode to use the same hashing policies that are used in the 802.3ad and Xor mode. Change-Id: I276609e87e0ca213c4d1b17b79c5e0b0f3d0dd6f Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to ixgbe, ixgbevf, e1000e, igb and i40e. Jacob converts the ixgbe low_water into an array which allows the algorithm to output different values for different TCs and we can distinguish between them. Removes vlan_filter_disable() and vlan_filter_enable() in ixgbe so that we can do the work directly in set_rx_mode(). Changes the setting of multicast filters only when the interface is not in promiscuous mode for multicast packets in ixgbe. Improves MAC filter handling by adding mac_table API based on work done for igb, which includes functions to add/delete MAC filters. Mark changes register reads in ixgbe to an out-of-line function since register reads are slow. Emil provides a ixgbevf patch to update the driver description since it supports more than just 82599 parts now. David provides several cleanup patches for e1000e which resolve some checkpatch issues as well as changing occurrences of returning 0 or 1 in bool functions to returning true false or true. Carolyn provides several cleanup patches for igb which fix checkpatch warnings. Mitch provides a fix for i40evf where the driver would correctly allow the virtual function link state to be controlled by 'ip set link', but would not report it correctly back. This is fixed by filling out the appropriate field in the VF info struct. ==================== Signed-off-by: -

Alexey Charkov says: ==================== net: via-rhine: add support for on-chip Rhine controllers This series introduces platform bus (OpenFirmware) binding for via-rhine, as used in various ARM-based Systems-on-Chip by VIA/WonderMedia. This has been tested in OF configuration by myself on a WM8950-based VIA APC Rock development board and on a WM8850-based netbook, and in PCI configuration by Roger. Please note that the initial version of these patches was signed off by Roger, but some time has passed since then, so I'm not including his sign-off until explicit notice. Changes since v1: - Fixed indentation of function arguments - Switched to 'dev_is_pci' instead of string comparison on bus name - Dropped 'rhine,revision' DT attribute, put the revision into OF match table instead - Included actual device tree nodes where applicable ==================== Signed-off-by: -

The goal of this patch is to fix rtnelink notification. The main problem was about notification for fdb entry with more than one remote. Before the patch, when a remote was added to an existing fdb entry, the kernel advertised the first remote instead of the added one. Also when a remote was removed from a fdb entry with several remotes, the deleted remote was not advertised. Signed-off-by:

In ksz9021_load_values_from_of() val2 to val4 aren't tested against their initialization value. This causes the test to always succeed, and this value to be used as if it was loaded from the devicetree instead of being ignored, in case of a missing/invalid property in the ethernet OF device node. As a result, the value "0" is written to the relevant registers. Change the conditions to test against the right initialization value. Signed-off-by:

This patch allows to switch the netns when packet is encapsulated or decapsulated. In other word, the encapsulated packet is received in a netns, where the lookup is done to find the tunnel. Once the tunnel is found, the packet is decapsulated and injecting into the corresponding interface which stands to another netns. When one of the two netns is removed, the tunnel is destroyed.

Removed recv_pkt_list and lock, and updated related code, so that the locking overhead is reduced especially when multiple channels are in use. The recv_pkt_list isn't actually necessary because the packets are processed sequentially in each channel. It has been replaced by a local variable, and the related lock for this list is also removed. The is_data_pkt field is not used in receive path, so its assignment is cleaned up. Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to i40e and i40evf. Greg provides two patches for i40e, the first adds the netdev ops to support the addition of static FDB entries in the physical function (PF) MAC/VLAN filter table so that the virtual functions (VFs) can communicate with bridged virtual Ethernet ports such as those provided by the virtio driver. The second is to fix an issue where the assignment of a port VLAN after it is already up and running requires the VF driver to be reloaded, so print a message warning the host administrator about the need to reload the VF driver. In addition, knock the VF offline so that it does not continue to receive traffic not on the port VLAN assigned to it. Jesse provides a patch for i40e and i40evf to unhide and enable the PREFENA field in the receive host memory cache (RX-HMC) for best performance. Mitch provides a i40e patch to implement the net device op for Tx bandwidth setting. Catherine removes a firmware workaround that is no longer needed with the latest firmware for i40e. She also provides some minor cleanups as well bumps the driver versions. Anjali provides a fix for i40e displaying IPv4 flow director filters which needed additional information to be communicated up above in order for it to be displayed correctly. Shannon adds tracking of the NVM busy state so that the driver won't allow a new NVM update command until a completion event is received from the current update. Updates the admin queue API to reflect recent changes in the firmware. Also rearranges the "if netdev" logic to prepare for handling non-netdev VSIs. Lastly rework the fdir setup and tear down to use the newly created i40e_vsi_open() and i40e_vsi_close(), which also fixes a memory leak of the FDIR queue buffer info structs across a reset. ==================== Signed-off-by: -

Richard Guy Briggs says: ==================== audit: implement multicast socket for journald This is a patch set Eric Paris and I have been working on to add a restricted capability read-only netlink multicast socket to kernel audit to enable userspace clients such as systemd/journald to receive audit logs, in addition to the bidirectional auditd userspace client. Currently, auditd has the CAP_AUDIT_CONTROL and CAP_AUDIT_WRITE capabilities (but uses CAP_NET_ADMIN). The CAP_AUDIT_READ capability will be added for use by read-only AUDIT_NLGRP_READLOG multicast group clients to the kaudit subsystem. This will remove the dependence on CAP_NET_ADMIN for the multicast read-only socket. Patches 1-3 provide a way for per-protocol bind functions to signal an error and to be able to clean up after themselves. The first netfilter cleanup patch has already been accepted by a netfilter maintainer, though I don't see it upstream yet, so it is included for completeness. The second patch adds the per-protocol bind function return code to signal to the netlink code that no further processing should be done and to undo the work already done. V1: This rev fixes a bug introduced by flattening the code in the last posting. *V2: This rev moves the per-protocol bind call above the socket exposure call and refactors out the unbind procedure. The third provides a way per protocol to undo bind actions on DROP. Patches 4-6 implement the audit multicast socket with capability checking. The fourth patch adds the bind function capability check to multicast join requests for audit. The fifth patch adds the audit log read multicast group. An assumption has been made that systemd/journald reside in the initial network namespace. This could be changed to check the actual network namespace of systemd/journald should this assumption no longer be true since audit now supports all network namespaces. This version of the patch now directly sends the broadcast when the packet is ready rather than waiting until it passes the queue. The sixth checks if any clients actually exist before sending. Since the net tree is busier than the audit tree, conflicts are more likely and the audit patches depend on the net patches, it is proposed to have the net tree carry this entire patchset for 3.16. Are the net maintainers ok with this? https://bugzilla.redhat.com/show_bug.cgi?id=887992 First posted: https://www.redhat.com/archives/linux-audit/2013-January/msg00008.html https://lkml.org/lkml/2013/1/27/279 Please find source for a test program at: http://people.redhat.com/rbriggs/audit-multicast-listen/ ==================== Signed-off-by:
