From Floria Fainelli. 3) Allow 'ip address' commands to initiate multicast group join/leave, from Madhu Challa. 4) Many ipv4 FIB lookup optimizations from Alexander Duyck. 5) Support EBPF in cls_bpf classifier and act_bpf action, from Daniel Borkmann. 6) Remove the ugly compat support in ARP for ugly layers like ax25, rose, etc. And use this to clean up the neigh layer, then use it to implement MPLS support. All from Eric Biederman. 7) Support L3 forwarding offloading in switches, from Scott Feldman. 8) Collapse the LOCAL and MAIN ipv4 FIB tables when possible, to speed up route lookups even further. From Alexander Duyck. 9) Many improvements and bug fixes to the rhashtable implementation, from Herbert Xu and Thomas Graf. In particular, in the case where an rhashtable user bulk adds a large number of items into an empty table, we expand the table much more sanely. 10) Don't make the tcp_metrics hash table per-namespace, from Eric Biederman. 11) Extend EBPF to access SKB fields, from Alexei Starovoitov. 12) Split out new connection request sockets so that they can be established in the main hash table. Much less false sharing since hash lookups go direct to the request sockets instead of having to go first to the listener then to the request socks hashed underneath. From Eric Dumazet. 13) Add async I/O support for crytpo AF_ALG sockets, from Tadeusz Struk. 14) Support stable privacy address generation for RFC7217 in IPV6. From Hannes Frederic Sowa. 15) Hash network namespace into IP frag IDs, also from Hannes Frederic Sowa. 16) Convert PTP get/set methods to use 64-bit time, from Richard Cochran. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1816 commits) fm10k: Bump driver version to 0.15.2 fm10k: corrected VF multicast update fm10k: mbx_update_max_size does not drop all oversized messages fm10k: reset head instead of calling update_max_size fm10k: renamed mbx_tx_dropped to mbx_tx_oversized fm10k: update xcast mode before synchronizing multicast addresses fm10k: start service timer on probe fm10k: fix function header comment fm10k: comment next_vf_mbx flow fm10k: don't handle mailbox events in iov_event path and always process mailbox fm10k: use separate workqueue for fm10k driver fm10k: Set PF queues to unlimited bandwidth during virtualization fm10k: expose tx_timeout_count as an ethtool stat fm10k: only increment tx_timeout_count in Tx hang path fm10k: remove extraneous "Reset interface" message fm10k: separate PF only stats so that VF does not display them fm10k: use hw->mac.max_queues for stats fm10k: only show actual queues, not the maximum in hardware fm10k: allow creation of VLAN on default vid fm10k: fix unused warnings ...

The conflict hunks generated by GIT were very unhelpful, to say the least. It split functions in half and moved them around, when the real actual conflict only existed solely inside of one function, that being be_map_pci_bars(). So instead, to resolve this, I checked out be_main.c from the top of net-next, then I applied the be_main.c changes from 'net' since the last time I merged. And this worked beautifully. The inet_diag.c and sysctl_net_core.c conflicts were simple overlapping changes, and were easily to resolve. Signed-off-by: David S. Miller <davem@davemloft.net>

* | isdn: fix misspelling of current function in stringJulia Lawall2014-12-098-10/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | Replace a misspelled function name by %s and then __func__. In the first case, the print is just dropped, because kmalloc itself does enough error reporting. This was done using Coccinelle, including the use of Levenshtein distance, as proposed by Rasmus Villemoes. Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: David S.

* | mISDN: Deletion of unnecessary checks before the function call "vfree"Markus Elfring2014-11-211-4/+2
| | | | | | | | | | | | | | | | | | | | The vfree() function performs also input parameter validation. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: David S. Miller <davem@davemloft.net>
* | net: Add and use skb_copy_datagram_msg() helper.David S. Miller2014-11-051-1/+1
|/ | | | | | | | | | | | | | | This encapsulates all of the skb_copy_datagram_iovec() callers with call argument signature "skb, offset, msghdr->msg_iov, length". When we move to iov_iters in the networking, the iov_iter object will sit in the msghdr. Having a helper like this means there will be less places to touch during that transformation. Based upon descriptions and patch from Al Viro. Signed-off-by: David S. Miller <davem@davemloft.net>
* isdn/gigaset: fix usb_gigaset write_cmd result raceTilman Schmidt2014-10-141-1/+3
| | | | | | | | | | In usb_gigaset function gigaset_write_cmd(), the length field of the command buffer structure could be cleared by the transmit tasklet before it was used for the function's return value. Fix by copying to a local variable before scheduling the tasklet. Signed-off-by: Tilman Schmidt <tilman@imap.cc> Signed-off-by: David S. Miller <davem@davemloft.net>
* isdn/capi: don't return NULL from capi_cmd2str()Tilman Schmidt2014-10-141-2/+7
| | | | | | | | | | capi_cmd2str() is used in many places to build log messages. None of them is prepared to handle NULL as a result. Change the function to return printable string "INVALID_COMMAND" instead. Signed-off-by: Tilman Schmidt <tilman@imap.cc> Signed-off-by: David S. Miller <davem@davemloft.net>

* isdn/capi: prevent NULL pointer dereference on invalid CAPI commandTilman Schmidt2014-10-141-0/+7
| | | | | | | | | | An invalid CAPI 2.0 command/subcommand combination may retrieve a NULL pointer from the cpars[] array which will later be dereferenced by the parser routines. Fix by adding NULL pointer checks in strategic places. Signed-off-by: Tilman Schmidt <tilman@imap.cc> Signed-off-by: David S. Miller <davem@davemloft.net>
* isdn/capi: refactor command/subcommand table accessesTilman Schmidt2014-10-141-5/+18

* isdn/capi: prevent index overrun from command_2_index()Tilman Schmidt2014-10-141-0/+2
| | | | | | | | | | | | | | The result of the function command_2_index() is used to index two arrays mnames[] and cpars[] with max. index 0x4e but in its current form that function can produce results up to 3*(0x9+0x9)+0x7f = 0xb5. Fix by clamping all result values potentially overrunning the arrays to zero which is already handled as an invalid value. Re-spotted with Coverity.

| | | | | | | | | | | | Function capi20_manufacturer() is declared with unsigned int cmd argument but called with unsigned long. Fix by correcting the function prototype since the actual argument is part of the user visible API. Spotted with Coverity. Signed-off-by: Tilman Schmidt <tilman@imap.cc> Signed-off-by: David S. Miller <davem@davemloft.net>
* isdn/gigaset: fix non-heap pointer deallocationTilman Schmidt2014-10-141-41/+70
| | | | | | | | | | | | | | | at_state structures may be allocated individually or as part of a cardstate or bc_state structure. The disconnect() function handled both cases, creating a risk that it might try to deallocate an at_state structure that had not been allocated individually. Fix by splitting disconnect() into two variants handling cases with and without an associated B channel separately, and adding an explicit check. Spotted with Coverity.

* isdn/gigaset: limit raw CAPI message dump lengthTilman Schmidt2014-10-141-0/+2
| | | | | | | | | | | | In dump_rawmsg, the length field from a received data package was used unscrutinized, allowing an attacker to control the size of the allocated buffer and the number of times the output loop iterates. Fix by limiting to a reasonable value. Spotted with Coverity. Signed-off-by: Tilman Schmidt <tilman@imap.cc> Signed-off-by: David S. Miller <davem@davemloft.net>
* isdn/gigaset: make sure controller name is null terminatedTilman Schmidt2014-10-141-2/+2
| | | | | | | | | | | | In gigaset_isdn_regdev, the name field may not have a null terminator if the source string's length is equal to the buffer size. Fix by zero filling the structure and excluding the last byte of the name field from the copy. Spotted with Coverity. Signed-off-by: Tilman Schmidt <tilman@imap.cc> Signed-off-by: David S.

This is the result of discussions back in Chicago, and the hard work of several individuals. Now, when the ->ndo_start_xmit() method of a driver sees skb->xmit_more as true, it can choose to defer the doorbell telling the driver to start processing the new TX queue entires. skb->xmit_more means that the generic networking is guaranteed to call the driver immediately with another SKB to send. There is logic added to the qdisc layer to dequeue multiple packets at a time, and the handling mis-predicted offloads in software is now done with no locks held. Finally, pktgen is extended to have a "burst" parameter that can be used to test a multi-send implementation. Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4, virtio_net Adding support is almost trivial, so export more drivers to support this optimization soon. I want to thank, in no particular or implied order, Jesper Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann, David Tat, Hannes Frederic Sowa, and Rusty Russell. 2) PTP and timestamping support in bnx2x, from Michal Kalderon. 3) Allow adjusting the rx_copybreak threshold for a driver via ethtool, and add rx_copybreak support to enic driver. From Govindarajulu Varadarajan. 4) Significant enhancements to the generic PHY layer and the bcm7xxx driver in particular (EEE support, auto power down, etc.) from Florian Fainelli. 5) Allow raw buffers to be used for flow dissection, allowing drivers to determine the optimal "linear pull" size for devices that DMA into pools of pages. The objective is to get exactly the necessary amount of headers into the linear SKB area pre-pulled, but no more. The new interface drivers use is eth_get_headlen(). From WANG Cong, with driver conversions (several had their own by-hand duplicated implementations) by Alexander Duyck and Eric Dumazet. 6) Support checksumming more smoothly and efficiently for encapsulations, and add "foo over UDP" facility. From Tom Herbert. 7) Add Broadcom SF2 switch driver to DSA layer, from Florian Fainelli. 8) eBPF now can load programs via a system call and has an extensive testsuite. Alexei Starovoitov and Daniel Borkmann. 9) Major overhaul of the packet scheduler to use RCU in several major areas such as the classifiers and rate estimators. From John Fastabend. 10) Add driver for Intel FM10000 Ethernet Switch, from Alexander Duyck. 11) Rearrange TCP_SKB_CB() to reduce cache line misses, from Eric Dumazet. 12) Add Datacenter TCP congestion control algorithm support, From Florian Westphal. 13) Reorganize sk_buff so that __copy_skb_header() is significantly faster.
