Support for using UD and AF_IB is currently broken. The IB_CM_SIDR_REQ_RECEIVED message is not handled properly in cma_save_net_info() and we end up falling into code that will try and process the request as ipv4/ipv6, which will end up failing. The resolution is to add a check for the SIDR_REQ and call cma_save_ib_info() with a NULL path record. Change cma_save_ib_info() to copy the src sib info from the listen_id when the path record is NULL. Reported-by:

Problem reported by: Ted Kim <ted.h.kim@oracle.com>: We have a case where a Linux system and a non-Linux system are trying to interoperate. The Linux host is the active side and starts the connection establishment, but later decides to not go through with the connection setup and does rdma_destroy_id(). The rdma_destroy_id() eventually works its way down to cm_destroy_id() in core/cm.c, where a REJ is sent. The non-Linux system has some trouble recognizing the REJ because of: A. CM states which can't receive the REJ B. Some issues about REJ formatting (missing comm ID) ISSUE A: That part of the spec says, a Consumer Reject REJ can be sent for a connection abort, but it goes further and says: can send a REJ message with a "Consumer Reject" Reason code if they are in a CM state (i.e. REP Rcvd, MRA(REP) Sent, REQ Rcvd, MRA Sent) that allows a REJ to be sent (lines 35-38). Of the states listed there in that sentence, it would seem to limit the active side to using the Consumer Reject (for the abort case) in just the REP-Rcvd and MRA-REP-Sent states. That is basically only after the active side sees a REP (or alternatively goes down the state transitions to timeout in which case a Timeout REJ is sent). As a fix, in cm-destroy-id() move the IB-CM-MRA-REQ-RCVD case to the same as REQ-SENT. Essentially, make a REJ sent after getting an MRA on active side a timeout rather than Consumer- Reject, which is arguably more correct with the CM state diagrams previous to getting a REP.

We've got reports that ALC3226 (a Dell variant of ALC292) gives click noises at transition from D3 to D0 when the widget power-saving is enabled. Further debugging session showed that avoiding it isn't trivial, unfortunately, since paths are basically activated dynamically while the pins have been already enabled. This patch disables the widget power-saving for such codecs. Reported-by:

The widget (node) power-saves restore the widget states at each transition from D3 to D0 on each node. This was added in the commit [d545a57c:ALSA: hda - Sync node attributes at resume from widget power saving]. However, the test was rater false-positive; this wasn't needed for any codecs. Since the resync may take significant number of additional verbs to be executed, it's better to reduce it. Let's disable it for now again. Signed-off-by:

A non-percpu VIRQ (e.g., VIRQ_CONSOLE) may be freed on a different VCPU than it is bound to. This can result in a race between handle_percpu_irq() and removing the action in __free_irq() because handle_percpu_irq() does not take desc->lock. The interrupt handler sees a NULL action and oopses. Only use the percpu chip/handler for per-CPU VIRQs (like VIRQ_TIMER). # cat /proc/interrupts | grep virq 40: 87246 0 xen-percpu-virq timer0 44: 0 0 xen-percpu-virq debug0 47: 0 20995 xen-percpu-virq timer1 51: 0 0 xen-percpu-virq debug1 69: 0 0 xen-dyn-virq xen-pcpu 74: 0 0 xen-dyn-virq mce 75: 29 0 xen-dyn-virq hvc_console Signed-off-by:David Vrabel <david.vrabel@citrix.com> Cc: <stable@vger.kernel.org>

The PWM hardware on Pistachio platform has a maximum timebase steps value to 255. To fix it, let's introduce a compatible-specific data structure to contain the SoC-specific details and use it to specify a maximum timebase. Also, let's limit the minimum timebase to 16 steps, to allow a sane range of duty cycle steps. Fixes: 277bb6a2 ("pwm: Imagination Technologies PWM DAC driver") Signed-off-by:

Currently in snd_pcm_update_hw_ptr0 during interrupt, we consider there were double acknowledged interrupts when: 1. HW reported pointer is smaller than expected, and 2. Time from last update time (hdelta) is over half a buffer time. However, when HW reported pointer is only a few bytes smaller than expected, and when hdelta is just a little larger than half a buffer time (e.g. ping-pong buffer), it wrongly treats this IRQ as double acknowledged. The condition #2 uses jiffies, but jiffies is not high resolution since it is integer. We should consider jiffies inaccuracy. Signed-off-by:

Two watchdog changes that came through different trees had a non conflicting conflict, that is, one changed the semantics of a variable but no actual code conflict happened. So the merge appeared fine, but the resulting code did not behave as expected. Commit 195daf66 ("watchdog: enable the new user interface of the watchdog mechanism") changes the semantics of watchdog_user_enabled, which thereafter is only used by the functions introduced by b3738d29 ("watchdog: Add watchdog enable/disable all functions"). There further appears to be a distinct lack of serialization between setting and using watchdog_enabled, so perhaps we should wrap the {en,dis}able_all() things in watchdog_proc_mutex. This patch fixes a s2r failure reported by Michal; which I cannot readily explain. But this does make the code internally consistent again. Reported-and-tested-by:

Pull MTD fixes from Brian Norris: "Two MTD fixes for 4.1: - readtest: the signal-handling code was clobbering the error codes we should be handling/reporting in this test, rendering it useless. Noticed by Coverity. - the common SPI NOR flash DT binding (merged for 4.1-rc1) is being revised, so let's change that before 4.1 is minted" * tag 'for-linus-20150516' of git://git.infradead.org/linux-mtd: Documentation: dt: mtd: replace "nor-jedec" binding with "jedec, spi-nor" mtd: readtest: don't clobber error reports -
