Issuing set_termios() from irtty_close() causes kernel Oops for unplugged usb-serial devices. Since no other tty_ldisc calls set_termios() on close and no tty driver seem to check if tty->device_data is NULL or not on entry to set_termios(), the only solution I can come up with is to remove the irtty_stop_receiver() call, which only updates termios.

2014-02-17bonding: 802.3ad: make aggregator_identifier bond-privateJiri Bohac
aggregator_identifier is used to assign unique aggregator identifiers to aggregators of a bond during device enslaving. aggregator_identifier is currently a global variable that is zeroed in bond_3ad_initialize(). This sequence will lead to duplicate aggregator identifiers for eth1 and eth3: create bond0 change bond0 mode to 802.3ad enslave eth0 to bond0 //eth0 gets agg id 1 enslave eth1 to bond0 //eth1 gets agg id 2 create bond1 change bond1 mode to 802.3ad enslave eth2 to bond1 //aggregator_identifier is reset to 0 //eth2 gets agg id 1 enslave eth3 to bond0 //eth3 gets agg id 2 Fix this by making aggregator_identifier private to the bond.

2014-02-17usbnet: remove generic hard_header_len checkEmil Goode
This patch removes a generic hard_header_len check from the usbnet module that is causing dropped packages under certain circumstances for devices that send rx packets that cross urb boundaries. One example is the AX88772B which occasionally send rx packets that cross urb boundaries where the remaining partial packet is sent with no hardware header. When the buffer with a partial packet is of less number of octets than the value of hard_header_len the buffer is discarded by the usbnet module. With AX88772B this can be reproduced by using ping with a packet size between 1965-1976. The bug has been reported here: https://bugzilla.kernel.org/show_bug.cgi?id=29082 This patch introduces the following changes: - Removes the generic hard_header_len check in the rx_complete function in the usbnet module. - Introduces a ETH_HLEN check for skbs that are not cloned from within a rx_fixup callback. - For safety a hard_header_len check is added to each rx_fixup callback function that could be affected by this change. These extra checks could possibly be removed by someone who has the hardware to test. - Removes a call to dev_kfree_skb_any() and instead utilizes the dev->done list to queue skbs for cleanup. The changes place full responsibility on the rx_fixup callback functions that clone skbs to only pass valid skbs to the usbnet_skb_return function.

2014-02-17HID: hid-sensor-hub: quirk for STM Sensor hubArchana Patni
Added STM sensor hub vendor id in HID_SENSOR_HUB_ENUM_QUIRK to fix report descriptors. These devices uses old FW which uses logical 0 as minimum. In these, HID reports are not using proper collection classes. So we need to fix report descriptors,for such devices. This will not have any impact, if the FW uses logical 1 as minimum. We look for usage id for "power and report state", and modify logical minimum value to 1. This is a follow-up patch to commit id 875e36f8.

2014-02-17netdevice: add queue selection fallback handler for ndo_select_queueDaniel Borkmann
Add a new argument for ndo_select_queue() callback that passes a fallback handler. This gets invoked through netdev_pick_tx(); fallback handler is currently __netdev_pick_tx() as most drivers invoke this function within their customized implementation in case for skbs that don't need any special handling. This fallback handler can then be replaced on other call-sites with different queue selection methods (e.g. in packet sockets, pktgen etc). This also has the nice side-effect that __netdev_pick_tx() is then only invoked from netdev_pick_tx() and export of that function to modules can be undone. Suggested-by: David S.

2014-02-16ata: sata_mv: Cleanup only the initialized portsEzequiel Garcia
When an error occurs in the port initialization loop, currently the driver tries to cleanup all the ports. This results in a NULL pointer dereference if the ports were only partially initialized. Fix this by updating only the number of initialized ports (either with failure or successfully), before jumping to the error path and looping over that number in the cleanup loop.

2014-02-15of: search the best compatible match first in __of_match_node()Kevin Hao
Currently, of_match_node compares each given match against all node's compatible strings with of_device_is_compatible. To achieve multiple compatible strings per node with ordering from specific to generic, this requires given matches to be ordered from specific to generic. For most of the drivers this is not true and also an alphabetical ordering is more sane there. Therefore, this patch introduces a function to match each of the node's compatible strings against all given compatible matches without type and name first, before checking the next compatible string. This implies that node's compatibles are ordered from specific to generic while given matches can be in any order. If we fail to find such a match entry, then fall-back to the old method in order to keep compatibility.

2014-02-15i2c: mv64xxx: refactor message start to ensure proper initializationWolfram Sang
Because the offload mechanism can fall back to a standard transfer, having two seperate initialization states is unfortunate. Let's just have one state which does things consistently. This fixes a bug where some preparation was missing when the fallback happened. And it makes the code much easier to follow. To implement this, we put the check if offload is possible at the top of the offload setup function.

The struct driver_info ax88178_info is assigned the function asix_rx_fixup_common as it's rx_fixup callback. This means that FLAG_MULTI_PACKET must be set as this function is cloning the data and calling usbnet_skb_return. Not setting this flag leads to usbnet_skb_return beeing called a second time from within the rx_process function in the usbnet module.

2014-02-14Revert "OF: base: match each node compatible against all given matches first"Kevin Hao
This reverts commit 105353145eafb3ea919f5cdeb652a9d8f270228e. Stephen Chivers reported this is broken as we will get a match entry '.type = "serial"' instead of the '.compatible = "ns16550"' in the following scenario: serial0: serial@4500 { compatible = "fsl,ns16550", "ns16550"; } struct of_device_id of_platform_serial_table[] = { { .compatible = "ns8250", .data = (void *)PORT_8250, }, { .compatible = "ns16450", .data = (void *)PORT_16450, }, { .compatible = "ns16550a", .data = (void *)PORT_16550A, }, { .compatible = "ns16550", .data = (void *)PORT_16550, }, { .compatible = "ns16750", .data = (void *)PORT_16750, }, { .compatible = "ns16850", .data = (void *)PORT_16850, }, ... { .type = "serial", .data = (void *)PORT_UNKNOWN, }, { /* end of list */ }, }; So just revert this patch, we will use another implementation to find the best compatible match in a follow-on patch.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and power management fixes from Rafael Wysocki: "These include a fix for a recent intel_pstate regression, a fix for a regression in the ACPI-based PCI hotplug (ACPIPHP) code introduced during the 3.12 cycle, fixes for two bugs in the ACPI core introduced recently and a MAINTAINERS update related to cpufreq. Specifics: - Fix for a recent regression in the intel_pstate driver that introduced a race condition causing systems to crash during initialization in some situations. This removes the affected code altogether. From Dirk Brandewie. - ACPIPHP fix for a regression introduced during the 3.12 cycle causing devices to be dropped as a result of bus check notifications after system resume on some systems due to the way ACPIPHP interprets _STA return values (arguably incorrectly). From Mika Westerberg. - ACPI dock driver fix for a problem causing docking to fail due to a check that always fails after recent ACPI core changes (found by code inspection). - ACPI container driver fix to prevent memory from being leaked in an error code path after device_register() failures. - Update of the arm_big_little cpufreq driver maintainer's e-mail address" * tag 'pm+acpi-3.14-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: MAINTAINERS / cpufreq: update Sudeep's email address intel_pstate: Remove energy reporting from pstate_sample tracepoint ACPI / container: Fix error code path in container_device_attach() ACPI / hotplug / PCI: Relax the checking of _STA return values ACPI / dock: Use acpi_device_enumerated() to check if dock is present

Pull EDAC fixes from Borislav Petkov: "Fix polling timeout setting through sysfs. You're surely wondering why the patches are not based on an rc. Well, Andrew sent you 79040cad3f82 ("drivers/edac/edac_mc_sysfs.c: poll timeout cannot be zero sent you") already (it got in in -rc2) but it is not enough as a fix because for one, setting too low polling intervals (< 1sec) don't make any sense and cause unnecessary polling load on the system. Then, even if we set some interval, we explode with [ 4143.094342] WARNING: CPU: 1 PID: 0 at kernel/workqueue.c:1393 __queue_work+0x1d7/0x340() because the workqueue setup path is used also for the timeout period resetting and we're doing INIT_DELAYED_WORK() on an already active workqueue.
