2014-04-16[media] media: davinci: vpbe: use v4l2_fh for priority handlingLad, Prabhakar1-32/+7
This patch migrates the vpbe driver to use v4l2_fh for priority handling. This also fixes v4l2-compliance test. Signed-off-by: Lad, Prabhakar <prabhakar.csengg@gmail.com> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-04-16[media] bttv: Add support for PCI-8604PWDaniel Glöckner2-0/+111
This patch adds support for the PCI-8604PW card equipped with four 878A. It is unknown who the manufacturer of this card is and no drivers were available during development of the patch. According to images found online, the card is originally sold with Linux DVR software. A CPLD on the card prevents the 878A from requesting access to the bus until an initialization sequence has been issued via GPIOs. The implemented sequence uses the minimum number of GPIOs needed to successfully unlock bus access. As there are many more GPIOs connected to the CPLD, it is very likely that some of the others have an influence on the bus arbitration scheduling. This should be investigated further in case of performance issues. The tested card contains an EEPROM on one of the 878A, but it is completely empty (i.e. contains only 0xff), so it is not possible to detect the card.

2014-04-16[media] adv7842: Disable access to EDID DDC lines before chip power upMartin Bugge1-3/+6
In core_init make sure access to EDID DDC lines are disabled before chip is powered up. Also DISABLE_AUTO_EDID before power up. The correct setting is applied later when setting the EDID. Some sources (MAC) kept on reading EDID even when Hotplug was low and in the short period in core_init before the DDC lines was enabled read a corrupt EDID.

2014-04-16[media] v4l2-ioctl.c: fix sparse __user-related warningsHans Verkuil1-5/+5
Fix the use of __user in the check_array_args() prototype: instead of using 'void * __user *' you should use 'void __user **' for sparse to understand this correctly. This also required the use of __force in the '*kernel_ptr = user_ptr' assignment. Also replace a wrong cast (void *) with the correct one (void **) in check_array_args(). This fixes these sparse warnings: drivers/media/v4l2-core/v4l2-ioctl.c:2284:35: warning: incorrect type in assignment (different address spaces) drivers/media/v4l2-core/v4l2-ioctl.c:2301:35: warning: incorrect type in assignment (different address spaces) drivers/media/v4l2-core/v4l2-ioctl.c:2319:35: warning: incorrect type in assignment (different address spaces) drivers/media/v4l2-core/v4l2-ioctl.c:2386:57: warning: incorrect type in argument 4 (different address spaces) drivers/media/v4l2-core/v4l2-ioctl.c:2420:29: warning: incorrect type in assignment (different address spaces) Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

Hence the sparse errors. I've replaced this by introducing three variants of the call_ macros: call_*op for int returns, call_void_*op for void returns and call_ptr_*op for pointer returns. That's the bad news. The good news is that the fail_*op macros could be removed since the call_*op macros now have enough information to determine if the op succeeded or not and can increment the op counter only on success. This at least makes it more robust w.r.t. future changes.

2014-04-15[media] Prefer gspca_sonixb over sn9c102 for all devicesJean Delvare2-4/+0
The sn9c102 driver is deprecated. It was moved to staging in anticipation of its removal in a future kernel version. However, USB devices 0C45:6024 and 0C45:6025 are still handled by sn9c102 when both sn9c102 and gspca_sonixb are enabled. We must migrate all the users of these devices to the gspca_sonixb driver now, so that it gets sufficient testing before the sn9c102 driver is finally phased out.

2014-04-12sym53c8xx_2: Set DID_REQUEUE return code when aborting squeueMikulas Patocka1-0/+4
This patch fixes I/O errors with the sym53c8xx_2 driver when the disk returns QUEUE FULL status. When the controller encounters an error (including QUEUE FULL or BUSY status), it aborts all not yet submitted requests in the function sym_dequeue_from_squeue. This function aborts them with DID_SOFT_ERROR. If the disk has full tag queue, the request that caused the overflow is aborted with QUEUE FULL status (and the scsi midlayer properly retries it until it is accepted by the disk), but the sym53c8xx_2 driver aborts the following requests with DID_SOFT_ERROR --- for them, the midlayer does just a few retries and then signals the error up to sd. The result is that disk returning QUEUE FULL causes request failures. The error was reproduced on 53c895 with COMPAQ BD03685A24 disk (rebranded ST336607LC) with command queue 48 or 64 tags. The disk has 64 tags, but under some access patterns it return QUEUE FULL when there are less than 64 pending tags. The SCSI specification allows returning QUEUE FULL anytime and it is up to the host to retry.

Pull yet more networking updates from David Miller: 1) Various fixes to the new Redpine Signals wireless driver, from Fariya Fatima. 2) L2TP PPP connect code takes PMTU from the wrong socket, fix from Dmitry Petukhov. 3) UFO and TSO packets differ in whether they include the protocol header in gso_size, account for that in skb_gso_transport_seglen(). From Florian Westphal. 4) If VLAN untagging fails, we double free the SKB in the bridging output path. From Toshiaki Makita. 5) Several call sites of sk->sk_data_ready() were referencing an SKB just added to the socket receive queue in order to calculate the second argument via skb->len. This is dangerous because the moment the skb is added to the receive queue it can be consumed in another context and freed up. It turns out also that none of the sk->sk_data_ready() implementations even care about this second argument. So just kill it off and thus fix all these use-after-free bugs as a side effect. 6) Fix inverted test in tcp_v6_send_response(), from Lorenzo Colitti. 7) pktgen needs to do locking properly for LLTX devices, from Daniel Borkmann. 8) xen-netfront driver initializes TX array entries in RX loop :-) From Vincenzo Maffione. 9) After refactoring, some tunnel drivers allow a tunnel to be configured on top itself.

Mark fixes an issue with ixgbe and ixgbevf by adding a bit to indicate when workqueues have been initialized. This permits the register read error handling from attempting to use them prior to that, which also generates warnings. Checking for a detected removal after initializing the work queues allows the probe function to return an error without getting the workqueue involved. Further, if the error_detected callback is entered before the workqueues are initialized, exit without recovery since the device initialization was so truncated. Francois Romieu provides several patches to all the drivers to remove the open coded skb_cow_head. Jakub Kicinski provides a fix for igb where last_rx_timestamp should be updated only when Rx time stamp is read. Mitch provides a fix for i40evf where a recent change broke the RSS LUT programming causing it to be programmed with all 0's. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

The sun4i-emac driver is rather primitive, and doesn't support promiscuous mode. This makes usage such as bridging impossible, which is a shame on virtualization capable HW such as the Allwinner A20. The fix is fairly simple: move the RX setup code to the ndo_set_rx_mode vector, and add the required HW configuration when IFF_PROMISC is passed by the core code. This has been tested on a generic A20 box running a few virtual machines hanging off a bridge with the EMAC chip as the link to the outside world.

2014-04-11target/tcm_fc: Fix use-after-free of ft_tpgAndy Grover1-0/+1
ft_del_tpg checks tpg->tport is set before unlinking the tpg from the tport when the tpg is being removed. Set this pointer in ft_tport_create, or the unlinking won't happen in ft_del_tpg and tport->tpg will reference a deleted object. This patch sets tpg->tport in ft_tport_create, because that's what ft_del_tpg checks, and is the only way to get back to the tport to clear tport->tpg. The bug was occuring when: - lport created, tport (our per-lport, per-provider context) is allocated. tport->tpg = NULL - tpg created - a PRLI is received. ft_tport_create is called, tpg is found and tport->tpg is set - tpg removed. ft_tpg is freed in ft_del_tpg. Since tpg->tport was not set, tport->tpg is not cleared and points at freed memory - Future calls to ft_tport_create return tport via first conditional, instead of searching for new tpg by calling ft_lport_find_tpg. tport->tpg is still invalid, and will access freed memory. see https://bugzilla.redhat.com/show_bug.cgi?id=1071340 Cc: stable@vger.kernel.org # 3.0+ Signed-off-by: Andy Grover <agrover@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
2014-04-11target: Add check to prevent Abort Task from aborting itselfAlex Leung1-0/+5
This patch addresses an issue that occurs when an ABTS is received for an se_cmd that completes just before the sess_cmd_list is searched in core_tmr_abort_task(). When the sess_cmd_list is searched, since the ABTS and the FCP_CMND being aborted (that just completed) both have the same OXID, TFO->get_task_tag(TMR) returns a value that matches tmr->ref_task_tag (from TFO->get_task_tag(FCP_CMND)), and the Abort Task tries to abort itself. When this occurs, transport_wait_for_tasks() hangs forever since the TMR is waiting for itself to finish. This patch adds a check to core_tmr_abort_task() to make sure the TMR does not attempt to abort itself.

previous interrupts When the Ethernet interface is put down and up with heavy Ethernet traffic, then there is prossibility of an interrupt waiting in irq controller to be processed, so when the interface is brought up again just after enable interrupt, it goes to ISR due to the previous unhandled interrutp and in ISR napi is not scheduled as the napi is not enabled in ndo_open which results in disabled interrupt for CPSW and no packets are received in cpsw.

2014-04-11drivers: net: cpsw: discard all packets received when interface is downMugunthan V N1-1/+1
When the Ethernet interface is brought down during high Ethernet traffic, then cpsw creates the following warn dump. When cpdma has already processed the packet then the status will be greater than 0, so the cpsw_rx_handler considers that the interface is up and try to resubmit one more rx buffer to cpdma which fails as the DMA is in teardown process. This can be avoided by checking the interface state and then process the received packet, if the interface is down just discard and free the skb and return.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull more ACPI and power management fixes and updates from Rafael Wysocki: "This is PM and ACPI material that has emerged over the last two weeks and one fix for a CPU hotplug regression introduced by the recent CPU hotplug notifiers registration series. Included are intel_idle and turbostat updates from Len Brown (these have been in linux-next for quite some time), a new cpufreq driver for powernv (that might spend some more time in linux-next, but BenH was asking me so nicely to push it for 3.15 that I couldn't resist), some cpufreq fixes and cleanups (including fixes for some silly breakage in a couple of cpufreq drivers introduced during the 3.14 cycle), assorted ACPI cleanups, wakeup framework documentation fixes, a new sysfs attribute for cpuidle and a new command line argument for power domains diagnostics. Specifics: - Fix for a recently introduced CPU hotplug regression in ARM KVM from Ming Lei. - Fixes for breakage in the at32ap, loongson2_cpufreq, and unicore32 cpufreq drivers introduced during the 3.14 cycle (-stable material) from Chen Gang and Viresh Kumar. - New powernv cpufreq driver from Vaidyanathan Srinivasan, with bits from Gautham R Shenoy and Srivatsa S Bhat. - Exynos cpufreq driver fix preventing it from being included into multiplatform builds that aren't supported by it from Sachin Kamat. - cpufreq cleanups related to the usage of the driver_data field in struct cpufreq_frequency_table from Viresh Kumar. - cpufreq ppc driver cleanup from Sachin Kamat. - Intel BayTrail support for intel_idle and ACPI idle from Len Brown. - Intel CPU model 54 (Atom N2000 series) support for intel_idle from Jan Kiszka. - intel_idle fix for Intel Ivy Town residency targets from Len Brown. - turbostat updates (Intel Broadwell support and output cleanups) from Len Brown. - New cpuidle sysfs attribute for exporting C-states' target residency information to user space from Daniel Lezcano. - New kernel command line argument to prevent power domains enabled by the bootloader from being turned off even if they are not in use (for diagnostics purposes) from Tushar Behera. - Fixes for wakeup sysfs attributes documentation from Geert Uytterhoeven. - New ACPI video blacklist entry for ThinkPad Helix from Stephen Chandler Paul. - Assorted ACPI cleanups and a Kconfig help update from Jonghwan Choi, Zhihui Zhang, Hanjun Guo" * tag 'pm+acpi-3.15-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (28 commits) ACPI: Update the ACPI spec information in Kconfig arm, kvm: fix double lock on cpu_add_remove_lock cpuidle: sysfs: Export target residency information cpufreq: ppc: Remove duplicate inclusion of fsl_soc.h cpufreq: create another field .flags in cpufreq_frequency_table cpufreq: use kzalloc() to allocate memory for cpufreq_frequency_table cpufreq: don't print value of .driver_data from core cpufreq: ia64: don't set .driver_data to index cpufreq: powernv: Select CPUFreq related Kconfig options for powernv cpufreq: powernv: Use cpufreq_frequency_table.driver_data to store pstate ids cpufreq: powernv: cpufreq driver for powernv platform cpufreq: at32ap: don't declare local variable as static cpufreq: loongson2_cpufreq: don't declare local variable as static cpufreq: unicore32: fix typo issue for 'clk' cpufreq: exynos: Disable on multiplatform build PM / wakeup: Correct presence vs. emptiness of wakeup_* attributes PM / domains: Add pd_ignore_unused to keep power domains enabled ACPI / dock: Drop dock_device_ids[] table ACPI / video: Favor native backlight interface for ThinkPad Helix ACPI / thermal: Fix wrong variable usage in debug statement ...
