Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next

2012-12-13T02:07:07Z

Pull networking changes from David Miller: 1) Allow to dump, monitor, and change the bridge multicast database using netlink. From Cong Wang. 2) RFC 5961 TCP blind data injection attack mitigation, from Eric Dumazet. 3) Networking user namespace support from Eric W. Biederman. 4) tuntap/virtio-net multiqueue support by Jason Wang. 5) Support for checksum offload of encapsulated packets (basically, tunneled traffic can still be checksummed by HW). From Joseph Gasparakis. 6) Allow BPF filter access to VLAN tags, from Eric Dumazet and Daniel Borkmann. 7) Bridge port parameters over netlink and BPDU blocking support from Stephen Hemminger. 8) Improve data access patterns during inet socket demux by rearranging socket layout, from Eric Dumazet. 9) TIPC protocol updates and cleanups from Ying Xue, Paul Gortmaker, and Jon Maloy. 10) Update TCP socket hash sizing to be more in line with current day realities. The existing heurstics were choosen a decade ago. From Eric Dumazet. 11) Fix races, queue bloat, and excessive wakeups in ATM and associated drivers, from Krzysztof Mazur and David Woodhouse. 12) Support DOVE (Distributed Overlay Virtual Ethernet) extensions in VXLAN driver, from David Stevens. 13) Add "oops_only" mode to netconsole, from Amerigo Wang. 14) Support set and query of VEB/VEPA bridge mode via PF_BRIDGE, also allow DCB netlink to work on namespaces other than the initial namespace. From John Fastabend. 15) Support PTP in the Tigon3 driver, from Matt Carlson. 16) tun/vhost zero copy fixes and improvements, plus turn it on by default, from Michael S. Tsirkin. 17) Support per-association statistics in SCTP, from Michele Baldessari. And many, many, driver updates, cleanups, and improvements. Too numerous to mention individually. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1722 commits) net/mlx4_en: Add support for destination MAC in steering rules net/mlx4_en: Use generic etherdevice.h functions. net: ethtool: Add destination MAC address to flow steering API bridge: add support of adding and deleting mdb entries bridge: notify mdb changes via netlink ndisc: Unexport ndisc_{build,send}_skb(). uapi: add missing netconf.h to export list pkt_sched: avoid requeues if possible solos-pci: fix double-free of TX skb in DMA mode bnx2: Fix accidental reversions. bna: Driver Version Updated to 3.1.2.1 bna: Firmware update bna: Add RX State bna: Rx Page Based Allocation bna: TX Intr Coalescing Fix bna: Tx and Rx Optimizations bna: Code Cleanup and Enhancements ath9k: check pdata variable before dereferencing it ath5k: RX timestamp is reported at end of frame ath9k_htc: RX timestamp is reported at end of frame ...

ptp: remove use of __devexit

2012-11-28T20:12:32Z

CONFIG_HOTPLUG is going away as an option so __devexit is no longer needed. Signed-off-by: Bill Pemberton Acked-by: Richard Cochran Signed-off-by: Greg Kroah-Hartman

ptp: reduce stack usage when measuring the system time offset

2012-11-26T22:22:14Z

This patch removes the large buffer from the stack of the system offset ioctl and replaces it with a kmalloced buffer. Signed-off-by: Richard Cochran Signed-off-by: David S. Miller

pch_gbe, ptp_pch: Fix the dependency direction between these drivers

2012-11-18T03:11:45Z

In commit a24006ed12616bde1bbdb26868495906a212d8dc ('ptp: Enable clock drivers along with associated net/PHY drivers') I wrongly made PTP_1588_CLOCK_PCH depend on PCH_GBE. The dependency is really the other way around. Therefore make PCH_GBE select PTP_1588_CLOCK_PCH and remove the 'default y' from the latter.

ptp: add an ioctl to compare PHC time with system time

2012-11-01T15:41:34Z

This patch adds an ioctl for PTP Hardware Clock (PHC) devices that allows user space to measure the time offset between the PHC and the system clock. Rather than hard coding any kind of estimation algorithm into the kernel, this patch takes the more flexible approach of just delivering an array of raw clock readings. In that way, the user space clock servo may be adapted to new and different hardware clocks. Signed-off-by: Richard Cochran Acked-by: Jacob Keller Signed-off-by: David S. Miller

ptp: Enable clock drivers along with associated net/PHY drivers

2012-11-01T15:35:18Z

Where a PTP clock driver is associated with a net or PHY driver, it should be enabled automatically whenever that driver is enabled. Therefore: - Make PTP clock drivers select rather than depending on PTP_1588_CLOCK - Remove separate boolean options for PTP clock drivers that are built as part of net driver modules. (This also fixes cases where the PTP subsystem is wrongly forced to be built-in.) - Set 'default y' for PTP clock drivers that depend on specific net drivers but are built separately Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller

ptp: Make PTP_1588_CLOCK select rather than depend on PPS

2012-11-01T15:35:18Z

PTP hardware clock drivers that select PTP_1588_CLOCK must currently also select PPS. For those drivers that don't, the user must enable PPS, then enable PTP_1588_CLOCK, then the driver. Simplify things for developers and users by putting this selection in one place. Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller

pps, ptp: Remove dependencies on EXPERIMENTAL

2012-11-01T15:35:17Z

These are now established subsystems, and we want drivers to be able to select PPS and PTP_1588_CLOCK without depending on EXPERIMENTAL. Further, the use of EXPERIMENTAL is now deprecated in general. Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller
