Pull networking fixes from David Miller: 1) The value choosen for the new SO_MAX_PACING_RATE socket option on parisc was very poorly choosen, let's fix it while we still can. From Eric Dumazet. 2) Our generic reciprocal divide was found to handle some edge cases incorrectly, part of this is encoded into the BPF as deep as the JIT engines themselves. Just use a real divide throughout for now. From Eric Dumazet. 3) Because the initial lookup is lockless, the TCP metrics engine can end up creating two entries for the same lookup key. Fix this by doing a second lookup under the lock before we actually create the new entry. From Christoph Paasch. 4) Fix scatter-gather list init in usbnet driver, from Bjørn Mork. 5) Fix unintended 32-bit truncation in cxgb4 driver's bit shifting. From Dan Carpenter. 6) Netlink socket dumping uses the wrong socket state for timewait sockets. Fix from Neal Cardwell. 7) Fix netlink memory leak in ieee802154_add_iface(), from Christian Engelmayer. 8) Multicast forwarding in ipv4 can overflow the per-rule reference counts, causing all multicast traffic to cease. Fix from Hannes Frederic Sowa. 9) via-rhine needs to stop all TX queues when it resets the device, from Richard Weinberger. 10) Fix RDS per-cpu accesses broken by the this_cpu_* conversions.

ipv6: simplify detection of first operational link-local address on interface

2014-01-18T02:10:01Z

In commit 1ec047eb4751e3 ("ipv6: introduce per-interface counter for dad-completed ipv6 addresses") I build the detection of the first operational link-local address much to complex. Additionally this code now has a race condition. Replace it with a much simpler variant, which just scans the address list when duplicate address detection completes, to check if this is the first valid link local address and send RS and MLD reports then.

i2c: Re-instate body of i2c_parent_is_i2c_adapter()

2014-01-14T16:11:13Z

The body of i2c_parent_is_i2c_adapter() is currently guarded by I2C_MUX. It should be CONFIG_I2C_MUX instead. Among potentially other problems, this resulted in i2c_lock_adapter() only locking I2C mux child adapters, and not the parent adapter. In turn, this could allow inter-mingling of mux child selection and I2C transactions, which could result in I2C transactions being directed to the wrong I2C bus, and possibly even switching between busses in the middle of a transaction. One concrete issue caused by this bug was corrupted HDMI EDID reads during boot on the NVIDIA Tegra Seaboard system, although this only became apparent in recent linux-next, when the boot timing was changed just enough to trigger the race condition.

seqlock: Use raw_ prefix instead of _no_lockdep

2014-01-12T09:13:59Z

Linus disliked the _no_lockdep() naming, so instead use the more-consistent raw_* prefix to the non-lockdep enabled seqcount methods. This also adds raw_ methods for the write operations as well, which will be utilized in a following patch.

net: core: explicitly select a txq before doing l2 forwarding

2014-01-10T18:23:08Z

Currently, the tx queue were selected implicitly in ndo_dfwd_start_xmit(). The will cause several issues: - NETIF_F_LLTX were removed for macvlan, so txq lock were done for macvlan instead of lower device which misses the necessary txq synchronization for lower device such as txq stopping or frozen required by dev watchdog or control path. - dev_hard_start_xmit() was called with NULL txq which bypasses the net device watchdog. - dev_hard_start_xmit() does not check txq everywhere which will lead a crash when tso is disabled for lower device. Fix this by explicitly introducing a new param for .ndo_select_queue() for just selecting queues in the case of l2 forwarding offload. netdev_pick_tx() was also extended to accept this parameter and dev_queue_xmit_accel() was used to do l2 forwarding transmission. With this fixes, NETIF_F_LLTX could be preserved for macvlan and there's no need to check txq against NULL in dev_hard_start_xmit(). Also there's no need to keep a dedicated ndo_dfwd_start_xmit() and we can just reuse the code of dev_queue_xmit() to do the transmission. In the future, it was also required for macvtap l2 forwarding support since it provides a necessary synchronization method.

Pull ACPI and PM fixes and new device IDs from Rafael Wysocki: "These commits, except for one, are regression fixes and the remaining one fixes a divide error leading to a kernel panic. The majority of the regressions fixed here were introduced during the 3.12 cycle, one of them is from this cycle and one is older. Specifics: - VGA switcheroo was broken for some users as a result of the ACPI-based PCI hotplug (ACPIPHP) changes in 3.12, because some previously ignored hotplug events started to be handled. The fix causes them to be ignored again. - There are two more issues related to cpufreq's suspend/resume handling changes from the 3.12 cycle addressed by Viresh Kumar's fixes. - intel_pstate triggers a divide error in a timer function if the P-state information it needs is missing during initialization. This leads to kernel panics on nested KVM clients and is fixed by failing the initialization cleanly in those cases. - PCI initalization code changes during the 3.9 cycle uncovered BIOS issues related to ACPI wakeup notifications (some BIOSes send them for devices that aren't supposed to support ACPI wakeup). Work around them by installing an ACPI wakeup notify handler for all PCI devices with ACPI support. - The Calxeda cpuilde driver's probe function is tagged as __init, which is incorrect and causes a section mismatch to occur during build. Fix from Andre Przywara removes the __init tag from there. - During the 3.12 cycle ACPIPHP started to print warnings about missing _ADR for devices that legitimately don't have it. Fix from Toshi Kani makes it only print the warnings where they make sense" * tag 'pm+acpi-3.13-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPIPHP / radeon / nouveau: Fix VGA switcheroo problem related to hotplug intel_pstate: Fail initialization if P-state information is missing ARM/cpuidle: remove __init tag from Calxeda cpuidle probe function PCI / ACPI: Install wakeup notify handlers for all PCI devs with ACPI cpufreq: preserve user_policy across suspend/resume cpufreq: Clean up after a failing light-weight initialization ACPI / PCI / hotplug: Avoid warning when _ADR not present
