2013-06-13xen-netback: don't de-reference vif pointer after having called xenvif_put()Jan Beulich1-5/+6
When putting vif-s on the rx notify list, calling xenvif_put() must be deferred until after the removal from the list and the issuing of the notification, as both operations dereference the pointer. Changing this got me to notice that the "irq" variable was effectively unused (and was of too narrow type anyway).

2013-06-13macvlan: don't touch promisc without passthroughMichael S. Tsirkin1-7/+13
commit df8ef8f3aaa6692970a436204c4429210addb23a "macvlan: add FDB bridge ops and macvlan flags" added a way to control NOPROMISC macvlan flag through netlink. However, with a non passthrough device we never set promisc on open, even if NOPROMISC is off. As a result: If userspace clears NOPROMISC on open, then does not clear it on a netlink command, promisc counter is not decremented on stop and there will be no way to clear it once macvlan is detached. If userspace does not clear NOPROMISC on open, then sets NOPROMISC on a netlink command, promisc counter will be decremented from 0 and overflow to fffffffff with no way to clear promisc. To fix, simply ignore NOPROMISC flag in a netlink command for non-passthrough devices, same as we do at open/close. Since we touch this code anyway - check dev_set_promiscuity return code and pass it to users (though an error here is unlikely). Cc: "David S.

2013-06-12rtc-at91rm9200: add shadow interrupt maskJohan Hovold1-1/+38
Add shadow interrupt-mask register which can be used on SoCs where the actual hardware register is broken. Note that some care needs to be taken to make sure the shadow mask corresponds to the actual hardware state. The added overhead is not an issue for the non-broken SoCs due to the relatively infrequent interrupt-mask updates. We do, however, only use the shadow mask value as a fall-back when it actually needed as there is still a theoretical possibility that the mask is incorrect (see the code for details).

2013-06-12rtc-at91rm9200: add match-table compile guardJohan Hovold1-0/+2
The members of Atmel's at91sam9x5 family (9x5) have a broken RTC interrupt mask register (AT91_RTC_IMR). It does not reflect enabled interrupts but instead always returns zero. The kernel's rtc-at91rm9200 driver handles the RTC for the 9x5 family. Currently when the date/time is set, an interrupt is generated and this driver neglects to handle the interrupt. The kernel complains about the un-handled interrupt and disables it henceforth. This not only breaks the RTC function, but since that interrupt is shared (Atmel's SYS interrupt) then other things break as well (e.g. the debug port no longer accepts characters). Tested on the at91sam9g25. Bug confirmed by Atmel. This patch (of 5): Add missing match-table compile guard.

2013-06-12drivers/rtc/rtc-twl.c: fix missing device_init_wakeup() when booted with ↵Tony Lindgren1-0/+1
device tree When booted in legacy mode device_init_wakeup() gets called by drivers/mfd/twl-core.c when the children are initialized. However, when booted using device tree, the children are created with of_platform_populate() instead add_children(). This means that the RTC driver will not have device_init_wakeup() set, and we need to call it from the driver probe like RTC drivers typically do. Without this we cannot test PM wake-up events on omaps for cases where there may not be any physical wake-up event.

If a new logical drive is added and the CCISS_REGNEWD ioctl is invoked (as is normal with the Array Configuration Utility) the process will hang as below. It attempts to acquire the same mutex twice, once in do_ioctl() and once in cciss_unlocked_open(). The BKL was recursive, the mutex isn't.

2013-06-12drivers/rtc/rtc-cmos.c: fix accidentally enabling rtc channelDerek Basehore1-1/+3
During resume, we call hpet_rtc_timer_init after masking an irq bit in hpet. This will cause the call to hpet_disable_rtc_channel to be undone if RTC_AIE is the only bit not masked. Allowing the cmos interrupt handler to run before resuming caused some issues where the timer for the alarm was not removed. This would cause other, later timers to not be cleared, so utilities such as hwclock would time out when waiting for the update interrupt.

Reports of DMA problems are still trickling in and are sitting in the kernel bugzilla. Until the PS code in ath9k is given a thorough review, disbale it by default.

Fix this by updating bss_modes[] to support the current list of modes and adding a check to prevent the out-of-bounds access from occuring in the future when more modes are added.

2013-06-12HID: multitouch: prevent memleak with the allocated nameBenjamin Tissoires1-4/+7
mt_free_input_name() was never called during .remove(): hid_hw_stop() removes the hid_input items in hdev->inputs, and so the list is therefore empty after the call. In the end, we never free the special names that has been allocated during .probe(). Restore the original name before freeing it to avoid acessing already freed pointer.

2013-06-12team: move add to port list before port enablementJiri Pirko1-1/+1
team_port_enable() adds port to port_hashlist. Reader sees port in team_get_port_by_index_rcu() and returns it, but team_get_first_port_txable_rcu() tries to go through port_list, where the port is not inserted yet -> NULL pointer dereference. Fix this by reordering port_list and port_hashlist insertion. Panic is easily triggeable when txing packets and adding/removing port in a loop.

2013-06-11qmi_wwan/cdc_ether: let qmi_wwan handle the Huawei E1820Bjørn Mork2-0/+7
Another QMI speaking Qualcomm based device, which should be driven by qmi_wwan, while cdc_ether should ignore it. Like on other Huawei devices, the wwan function can appear either as a single vendor specific interface or as a CDC ECM class function using separate control and data interfaces. The ECM control interface protocol is 0xff, likely in an attempt to indicate that vendor specific management is required. In addition to the near standard CDC class, Huawei also add vendor specific AT management commands to their firmwares. This is probably an attempt to support non-Windows systems using standard class drivers. Unfortunately, this part of the firmware is often buggy. Linux is much better off using whatever native vendor specific management protocol the device offers, and Windows uses, whenever possible. This means QMI in the case of Qualcomm based devices. The E1820 has been verified to work fine with QMI. Matching on interface number is necessary to distiguish the wwan function from serial functions in the single interface mode, as both function types will have class/subclass/function set to ff/ff/ff. The control interface number does not change in CDC ECM mode, so the interface number matching rule is sufficient to handle both modes. The cdc_ether blacklist entry is only relevant in CDC ECM mode, but using a similar interface number based rule helps document this as a transfer from one driver to another. Other Huawei 02/06/ff devices are left with the cdc_ether driver because we do not know whether they are based on Qualcomm chips. The Huawei specific AT command management is known to be somewhat hardware independent, and their usage of these class codes may also be independent of the modem hardware.

Complier may generate codes that re-read the tun->numqueues during tun_select_queue(). This may be a race if vlan->numqueues were changed in the same time and can lead unexpected result (e.g. very huge value). We need prevent the compiler from generating such codes by adding an ACCESS_ONCE() to make sure tun->numqueues were only read once.
