For the Bluetooth bits, Gustavo says: "Some fixes for 3.15. There is a revert for the intel driver, a new device id, and two important SSP fixes from Johan." On top of that... Ben Hutchings gives us a fix for an unbalanced irq enable in an rtl8192cu error path. Colin Ian King provides an rtlwifi fix for an uninitialized variable. Felix Fietkau brings a pair of ath9k fixes, one that corrects a hardware initialization value and another that removes an (unnecessary) flag that was being used in a way that led to a software tx queue hang in ath9k. Gertjan van Wingerde pushes a MAINTAINERS change to remove himself from the rt2x00 maintainer team. Hans de Goede fixes a brcmfmac firmware load hang. Larry Finger changes rtlwifi to use the correct queue for V0 traffic on rtl8192se. Rajkumar Manoharan corrects a race in ath9k driver initialization. Stanislaw Gruszka fixes an rt2x00 bug in which disabling beaconing once on USB devices led to permanently disabling beaconing for those devices.

2014-04-30gianfar: Avoid unnecessary reg accesses in adjust_link()Claudiu Manoil
For phy devices that don't issue interrupts upon link state changes, phylib polls the link state resulting in repeated calls to adjust_link(), even if the link state didn't change. As a result, some mac registers are repeatedly read and written with the same values, which is not ok. To fix this, adjust_link() has been refactored to check first whether the link state has changed and to take action only if needed, updating mac registers and local state variables. The 'new_state' local flag, set if one of the link params changed (link, speed or duplex), has been rendered useless and removed by this refactoring.

2014-04-30Revert "macvlan : fix checksums error when we are in bridge mode"Vlad Yasevich
This reverts commit 12a2856b604476c27d85a5f9a57ae1661fc46019. The commit above doesn't appear to be necessary any more as the checksums appear to be correctly computed/validated. Additionally the above commit breaks kvm configurations where one VM is using a device that support checksum offload (virtio) and the other VM does not. In this case, packets leaving virtio device will have CHECKSUM_PARTIAL set. The packets is forwarded to a macvtap that has offload features turned off. Since we use CHECKSUM_UNNECESSARY, the host does does not update the checksum and thus a bad checksum is passed up to the guest.

2014-04-30mactap: Fix checksum errors for non-gso packets in bridge modeVlad Yasevich
The following is a problematic configuration: VM1: virtio-net device connected to macvtap0@eth0 VM2: e1000 device connect to macvtap1@eth0 The problem is is that virtio-net supports checksum offloading and thus sends the packets to the host with CHECKSUM_PARTIAL set. On the other hand, e1000 does not support any acceleration. For small TCP packets (and this includes the 3-way handshake), e1000 ends up receiving packets that only have a partial checksum set. This causes TCP to fail checksum validation and to drop packets. As a result tcp connections can not be established. Commit 3e4f8b787370978733ca6cae452720a4f0c296b8 macvtap: Perform GSO on forwarding path. fixes this issue for large packets wthat will end up undergoing GSO. This commit adds a check for the non-GSO case and attempts to compute the checksum for partially checksummed packets in the non-GSO case.

There are some corner cases where the driver could get stuck with a full tid queue that is paused, leading to a software tx queue hang. Since the tx queueing rework, pausing per-tid queues on aggregation session setup is no longer necessary. The driver will assign sequence numbers to buffered frames when a new session is established, in order to get the correct starting sequence number. mac80211 prevents new frames from entering the queue during setup.

2014-04-30ath9k_hw: do not lower ANI setting below default on AR913xFelix Fietkau
When the amount of noise fluctuates strongly, low immunity settings can sometimes disrupt signal detection on AR913x chips. When that happens, no OFDM/CCK errors are reported anymore, and ANI tunes the radio to the lowest immunity settings. Usually rx/tx fails as well in that case. To fix this, keep noise immunity settings at or above ANI default level, which will keep radio parameters at or above INI values. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

2014-04-26i40e: fix Timesync Tx interrupt handler codeJacob Keller
This patch fixes the PTP Tx timestamp interrupt handler. The original code misinterpreted the interrupt handler design. We were clearing the ena_mask bit for the Timesync interrupts. This is done to indicate that the interrupt will be handled in a scheduled work item (instead of immediately) and that work item is responsible for re-enabling the interrupts. However, the Tx timestamp was being handled immediately and nothing was ever re-enabling it. This resulted in a single interrupt working for the life of the driver. This patch fixes the issue by instead clearing the bit from icr0 which is used to indicate that the interrupt was immediately handled and can be re-enabled right away. This patch also clears up a related issue due to writing the PRTTSYN_STAT_0 register, which was unintentionally clearing the cause bits for Timesync interrupts.

Starting with commit 2dc33bbc "bnx2x: Remove the sriov VFOP mechanism", the bnx2x started enforcing vlan credits for all vlan configurations. This exposed 2 issues: - Vlan credits are not returned once a VF is removed; this causes a leak of credits, and eventually will lead to VFs with no vlan credits. - A vlan credit must be set aside for the Hypervisor to use, and should not be visible to the VF. Although linux VFs at the moment do not support vlan configuration [from the VF side] which causes them to be resilient to this sort of issue, Windows VF over linux hypervisors might fail to load as the vlan credits become depleted.

2014-04-25Revert "Bluetooth: Enable autosuspend for Intel Bluetooth device"Marcel Holtmann
This reverts commit d2bee8fb6e18f6116aada39851918473761f7ab1. Enabling autosuspend for Intel Bluetooth devices has been shown to not work reliable. It does work for some people with certain combinations of USB host controllers, but for others it puts the device to sleep and it will not wake up for any event. These events can be important ones like HCI Inquiry Complete or HCI Connection Request. The events will arrive as soon as you poke the device with a new command, but that is not something we can do in these cases. Initially there were patches to the xHCI USB controller that fixed this for some people, but not for all. This could be well a problem somewhere in the USB subsystem or in the USB host controllers or just plain a hardware issue somewhere. At this moment we just do not know and the only safe action is to revert this patch.

2014-04-24brcmfmac: Fix brcmf_chip_ai_coredisable not applying reset bits to BCMA_IOCTLHans de Goede
brcmfmac has been broken on my cubietruck with a BCM43362: brcmfmac: brcmf_chip_recognition: found AXI chip: BCM43362, rev=1 brcmfmac: brcmf_c_preinit_dcmds: Firmware version = wl0: Apr 22 2013 14:50:00 version 5.90.195.89.6 FWID 01-b30a427d since commit 53036261033: "brcmfmac: update core reset and disable routines". The problem is that since this commit brcmf_chip_ai_resetcore no longer sets BCMA_IOCTL itself before bringing the core out of reset, instead relying on brcmf_chip_ai_coredisable to do so. But brcmf_chip_ai_coredisable is a nop of the chip is already in reset. This patch modifies brcmf_chip_ai_coredisable to always set BCMA_IOCTL even if the core is already in reset. This fixes brcmfmac hanging in firmware loading on my board.

The commit "ath9k: move sc_flags to ath_common" moved setting ATH_OP_INVALID flag below ieee80211_register_hw. This is causing the flag never being cleared randomly as the drv_start is called prior to setting flag. Fix this by setting the flag prior to register_hw.

2014-04-24can: sja1000_isa: add locking for indirect register access modeOliver Hartkopp
When accessing the SJA1000 controller registers in the indirect access mode, writing the register number and reading/writing the data has to be an atomic attempt. As the sja1000_isa driver is an old style driver with a fixed number of instances the locking variable depends on the same index like all the other configuration elements given on the module command line. As a positive side effect dev->dev_id is populated by the instance index, which was missing in 3e66d0138c05d9 ("can: populate netdev::dev_id for udev discrimination").

It's suffcient to kill the TXIE bit in the message control register even if the documentation of C and D CAN says that it's not allowed to do that while MSGVAL is set. Reality tells a different story and this change gives us another 2% of CPU back for not waiting on I/O.
