Pull networking updates from David Miller: "Highlights: 1) Steady transitioning of the BPF instructure to a generic spot so all kernel subsystems can make use of it, from Alexei Starovoitov. 2) SFC driver supports busy polling, from Alexandre Rames. 3) Take advantage of hash table in UDP multicast delivery, from David Held. 4) Lighten locking, in particular by getting rid of the LRU lists, in inet frag handling. From Florian Westphal. 5) Add support for various RFC6458 control messages in SCTP, from Geir Ola Vaagland. 6) Allow to filter bridge forwarding database dumps by device, from Jamal Hadi Salim. 7) virtio-net also now supports busy polling, from Jason Wang. 8) Some low level optimization tweaks in pktgen from Jesper Dangaard Brouer. 9) Add support for ipv6 address generation modes, so that userland can have some input into the process. From Jiri Pirko. 10) Consolidate common TCP connection request code in ipv4 and ipv6, from Octavian Purdila. 11) New ARP packet logger in netfilter, from Pablo Neira Ayuso. 12) Generic resizable RCU hash table, with intial users in netlink and nftables. From Thomas Graf. 13) Maintain a name assignment type so that userspace can see where a network device name came from (enumerated by kernel, assigned explicitly by userspace, etc.) From Tom Gundersen. 14) Automatic flow label generation on transmit in ipv6, from Tom Herbert. 15) New packet timestamping facilities from Willem de Bruijn, meant to assist in measuring latencies going into/out-of the packet scheduler, latency from TCP data transmission to ACK, etc" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1536 commits) cxgb4 : Disable recursive mailbox commands when enabling vi net: reduce USB network driver config options. tg3: Modify tg3_tso_bug() to handle multiple TX rings amd-xgbe: Perform phy connect/disconnect at dev open/stop amd-xgbe: Use dma_set_mask_and_coherent to set DMA mask net: sun4i-emac: fix memory leak on bad packet sctp: fix possible seqlock seadlock in sctp_packet_transmit() Revert "net: phy: Set the driver when registering an MDIO bus device" cxgb4vf: Turn off SGE RX/TX Callback Timers and interrupts in PCI shutdown routine team: Simplify return path of team_newlink bridge: Update outdated comment on promiscuous mode net-timestamp: ACK timestamp for bytestreams net-timestamp: TCP timestamping net-timestamp: SCHED timestamp on entering packet scheduler net-timestamp: add key to disambiguate concurrent datagrams net-timestamp: move timestamp flags out of sk_flags net-timestamp: extend SCM_TIMESTAMPING ancillary data struct cxgb4i : Move stray CPL definitions to cxgb4 driver tcp: reduce spurious retransmits due to transient SACK reneging qlcnic: Initialize dcbnl_ops before register_netdev ...

netlabel: shorter names for the NetLabel catmap funcs/structs

2014-08-01T15:17:37Z

Historically the NetLabel LSM secattr catmap functions and data structures have had very long names which makes a mess of the NetLabel code and anyone who uses NetLabel. This patch renames the catmap functions and structures from "*_secattr_catmap_*" to just "*_catmap_*" which improves things greatly. There are no substantial code or logic changes in this patch.

netlabel: fix the catmap walking functions

2014-08-01T15:17:29Z

The two NetLabel LSM secattr catmap walk functions didn't handle certain edge conditions correctly, causing incorrect security labels to be generated in some cases. This patch corrects these problems and converts the functions to use the new _netlbl_secattr_catmap_getnode() function in order to reduce the amount of repeated code.

netlabel: fix the horribly broken catmap functions

2014-08-01T15:17:17Z

The NetLabel secattr catmap functions, and the SELinux import/export glue routines, were broken in many horrible ways and the SELinux glue code fiddled with the NetLabel catmap structures in ways that we probably shouldn't allow. At some point this "worked", but that was likely due to a bit of dumb luck and sub-par testing (both inflicted by yours truly). This patch corrects these problems by basically gutting the code in favor of something less obtuse and restoring the NetLabel abstractions in the SELinux catmap glue code. Everything is working now, and if it decides to break itself in the future this code will be much easier to debug than the code it replaces. One noteworthy side effect of the changes is that it is no longer necessary to allocate a NetLabel catmap before calling one of the NetLabel APIs to set a bit in the catmap. NetLabel will automatically allocate the catmap nodes when needed, resulting in less allocations when the lowest bit is greater than 255 and less code in the LSMs. Cc: stable@vger.kernel.org Reported-by: Christian Evans Signed-off-by: Paul Moore Tested-by: Casey Schaufler

netlabel: fix a problem when setting bits below the previously lowest bit

2014-08-01T15:17:03Z

The NetLabel category (catmap) functions have a problem in that they assume categories will be set in an increasing manner, e.g. the next category set will always be larger than the last. Unfortunately, this is not a valid assumption and could result in problems when attempting to set categories less than the startbit in the lowest catmap node. In some cases kernel panics and other nasties can result. This patch corrects the problem by checking for this and allocating a new catmap node instance and placing it at the front of the list.

netlabel: Fix FSF address in file headers

2013-12-06T17:37:56Z

Several files refer to an old address for the Free Software Foundation in the file header comment. Resolve by replacing the address with the URL so that we do not have to keep updating the header comments anytime the address changes.

genetlink: only pass array to genl_register_family_with_ops()

2013-11-19T21:39:05Z

As suggested by David Miller, make genl_register_family_with_ops() a macro and pass only the array, evaluating ARRAY_SIZE() in the macro, this is a little safer. The openvswitch has some indirection, assing ops/n_ops directly in that code. This might ultimately just assign the pointers in the family initializations, saving the struct genl_family_and_ops and code (once mcast groups are handled differently.)
