The original FDB code submission wasn't correct and the code wasn't enabled. This removes some dead code (can use the common kernel code for fdb_del and fdb_dump) and correctly enables the fdb_add function pointer.

Pull ACPI power management fix from Rafael Wysocki: "This is just a one-liner fixing a regression introduced in 3.13 that broke system suspend on some Chromebooks. On those machines there are ACPI device objects for some I2C devices that can wake up the system from sleep states, but that is done via a platform-specific mechanism and the ACPI objects don't contain any wakeup-related information. When we started to use ACPI power management with those devices (which happened during the 3.13 cycle), their configuration confused the ACPI PM layer that returned error codes from suspend callbacks for them causing system suspend to fail. However, the ACPI PM layer can safely ignore the wakeup setting from a device driver if the ACPI object corresponding to the device in question doesn't contain wakeup information in which case the driver itself is responsible for setting up the device for system wakeup" * tag 'pm+acpi-3.18-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / PM: Ignore wakeup setting if the ACPI companion can't wake up

Most of it is again fixes and cleanups to ieee802154 related code from Alexander Aring. We've also got better handling of hardware error events along with a proper API for HCI drivers to notify the HCI core of such situations. There's also a minor fix for mgmt events as well as a sparse warning fix. The code for sending HCI commands synchronously also gets a fix where we might loose the completion event in the case of very fast HW (particularly easily reproducible with an emulated HCI device)." And... "Here's another bluetooth-next pull request for 3.19. We've got: - Various fixes, cleanups and improvements to ieee802154/mac802154 - Support for a Broadcom BCM20702A1 variant - Lots of lockdep fixes - Fixed handling of LE CoC errors that should trigger SMP" For the Atheros bits, Kalle says: "One ath6kl patch and rest for ath10k, but nothing really major which stands out. Most notable: o fix resume (Bartosz) o firmware restart is now faster and more reliable (Michal) o it's now possible to test hardware restart functionality without crashing the firmware using hw-restart parameter with simulate_fw_crash debugfs file (Michal)" On top of that...both ath9k and mwifiex get their usual level of updates.

Maciej W. Rozycki says: ==================== defxx: Assorted fixes, mainly for EISA This is another small series fixing issues with the defxx driver, mainly for EISA boards, but there's one patch for PCI as well. In the end, with the inexistent second IDE channel forcefully disabled in the IDE driver, I wasn't able to retrigger spurious IRQ 15 interrupts I previously saw and suspected the DEFEA to be the cause. So it looks to me these were real noise on IRQ 15 rather than the latency in interrupt acknowledge in the DEFEA board causing the slave 8259A to issue the spurious interrupt vector. In any case not an issue with the defxx driver, so nothing to do here unless the problem resurfaces. I haven't seen your announcement about opening net-next since the closure on Oct 6th, but from the patch traffic and the policy described in Documentation/networking/netdev-FAQ.txt I gather your tree is open. And these are bug fixes anyway, not new features, so please apply. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Use ESIC's memory area 1 (MEMCS1) and its Memory Address High Compare and Memory Address Low Compare registers to set up the MMIO range for decoding accesses to PDQ ASIC registers. Previously the PDQ ASIC was thought to be addressable with the memory area 0 (MEMCS0) and its Memory Address Compare and Memory Address Mask registers.

Commit c3ae62af ("tcp: should drop incoming frames without ACK flag set") was created to mitigate a security vulnerability in which a local attacker is able to inject data into locally-opened sockets by using TCP protocol statistics in procfs to quickly find the correct sequence number. This broke the RFC5961 requirement to send a challenge ACK in response to spurious RST packets, which was subsequently fixed by commit 7b514a88 ("tcp: accept RST without ACK flag"). Unfortunately, the RFC5961 requirement that spurious SYN packets be handled in a similar manner remains broken. RFC5961 section 4 states that: ... the handling of the SYN in the synchronized state SHOULD be performed as follows: 1) If the SYN bit is set, irrespective of the sequence number, TCP MUST send an ACK (also referred to as challenge ACK) to the remote peer: <SEQ=SND.NXT><ACK=RCV.NXT><CTL=ACK> After sending the acknowledgment, TCP MUST drop the unacceptable segment and stop processing further. By sending an ACK, the remote peer is challenged to confirm the loss of the previous connection and the request to start a new connection. A legitimate peer, after restart, would not have a TCB in the synchronized state. Thus, when the ACK arrives, the peer should send a RST segment back with the sequence number derived from the ACK field that caused the RST. This RST will confirm that the remote peer has indeed closed the previous connection. Upon receipt of a valid RST, the local TCP endpoint MUST terminate its connection. The local TCP endpoint should then rely on SYN retransmission from the remote end to re-establish the connection. This patch lets SYN packets through the discard added in c3ae62af, so that spurious SYN packets are properly dealt with as per the RFC. The challenge ACK is sent unconditionally and is rate-limited, so the original vulnerability is not reintroduced by this patch.

Not sure what I was thinking, but doing anything after releasing a refcount is suicidal or/and embarrassing. By the time we set skb->fclone to SKB_FCLONE_FREE, another cpu could have released last reference and freed whole skb. We potentially corrupt memory or trap if CONFIG_DEBUG_PAGEALLOC is set.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-11-20 This series contains updates to ixgbevf, i40e and i40evf. Emil updates ixgbevf with much of the work that Alex Duyck did while at Intel. First updates the driver to clear the status bits on allocation instead of in the cleanup routine, this way we can leave the recieve descriptor rings as a read only memory block until we actually have buffers to give back to the hardware. Clean up ixgbevf_clean_rx_irq() by creating ixgbevf_process_skb_field() to merge several similar operations into this new function. Cleanup temporary variables within the receive hot-path and reducing the scope of variables that do not need to exist outside the main loop. Save on stack space by just storing our updated values back in next_to_clean instead of using a stack variable, which also collapses the size the function. Improve performace on IOMMU enabled systems and reduce cache misses by changing the basic receive patch for ixgbevf so that instead of receiving the data into an skb, it is received into a double buffered page. Add netpoll support by creating ixgbevf_netpoll(), which is a callback for .ndo_poll_controller to allow for the VF interface to be used with netconsole. Mitch provides several cleanups and trivial fixes for i40e and i40evf. First is a fix the overloading of the msg_size field in the arq_event_info struct by splitting the field into two and renaming to indicate the actual function of each field. Updates code comments to match the actual function. Cleanup several checkpatch.pl warnings by adding or removing blank lines, aligning function parameters, and correcting over-long lines (which makes the code more readable). Shannon provides a patch for i40e to write the extra bits that will turn off the ITR wait for the interrupt, since we want the SW INT to go off as soon as possible. v2: updated patch 07 based on feedback from Alex Duyck by - adding pfmemalloc check to a new function for reusable page - moved atomic_inc outside of #if/else in ixgbevf_add_rx_frag() - reverted the removal of the API check in ixgbevf_change_mtu() ==================== Signed-off-by: NDavid S.

The current form of Tx coalescing works on a descriptor basis instead of on a packet basis and doesn't take into account TSO packets. Update the Tx coalescing support to work on a packet basis, taking into account the number of packets associated with a TSO transmit. Also, only activate the Tx timer if a timer value is set.
