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:

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:

Add a netlink multicast socket with one group to kaudit for "best-effort" delivery to read-only userspace clients such as systemd, in addition to the existing bidirectional unicast auditd userspace client. Currently, auditd is intended to use the CAP_AUDIT_CONTROL and CAP_AUDIT_WRITE capabilities, but actually uses CAP_NET_ADMIN. The CAP_AUDIT_READ capability is added for use by read-only AUDIT_NLGRP_READLOG netlink multicast group clients to the kaudit subsystem. This will safely give access to services such as systemd to consume audit logs while ensuring write access remains restricted for integrity. Signed-off-by:

Have the netlink per-protocol optional bind function return an int error code rather than void to signal a failure. This will enable netlink protocols to perform extra checks including capabilities and permissions verifications when updating memberships in multicast groups. In netlink_bind() and netlink_setsockopt() the call to the per-protocol bind function was moved above the multicast group update to prevent any access to the multicast socket groups before checking with the per-protocol bind function. This will enable the per-protocol bind function to be used to check permissions which could be denied before making them available, and to avoid the messy job of undoing the addition should the per-protocol bind function fail. The netfilter subsystem seems to be the only one currently using the per-protocol bind function. Signed-off-by:

Added a new ancillary load (bpf call in eBPF parlance) that produces a 32-bit random number. We are implementing it as an ancillary load (instead of an ISA opcode) because (a) it is simpler, (b) allows easy JITing, and (c) seems more in line with generic ISAs that do not have "get a random number" as a instruction, but as an OS call. The main use for this ancillary load is to perform random packet sampling. Signed-off-by:
