2017-03-31serial: 8250_EXAR: fix duplicate Kconfig text and add missing help textPaul Gortmaker1-2/+6
In commit d0aeaa83f0b0f7a92615bbdd6b1f96812f7dcfd2 ("serial: exar: split out the exar code from 8250_pci") the exar driver got its own Kconfig. However the text for the new option was never changed from the original 8250_PCI text, and hence it appears confusing when you get asked the same question twice: 8250/16550 PCI device support (SERIAL_8250_PCI) [Y/n/m/?] (NEW) 8250/16550 PCI device support (SERIAL_8250_EXAR) [Y/n/m] (NEW) Adding to the confusion, is that there is no help text for this new option to indicate it is specific to a certain family of cards. Fix both issues at the same time, as well as the space vs. tab issues introduced in the same commit.

2017-03-31serial: mxs-auart: Fix baudrate calculationUwe Kleine-König1-1/+1
The reference manual for the i.MX28 recommends to calculate the divisor as divisor = (UARTCLK * 32) / baud rate, rounded to the nearest integer , so let's do this. For a typical setup of UARTCLK = 24 MHz and baud rate = 115200 this changes the divisor from 6666 to 6667 and so the actual baud rate improves from 115211.521 Bd (error ≅ 0.01 %) to 115194.240 Bd (error ≅ 0.005 %).

2017-03-31dm raid: fix NULL pointer dereference for raid1 without bitmapDmitry Bilunov1-1/+1
Commit 4257e08 ("dm raid: support to change bitmap region size") introduced a bitmap resize call during preresume phase. User can create a DM device with "raid" target configured as raid1 with no metadata devices to hold superblock/bitmap info. It can be achieved using the following sequence: truncate -s 32M /dev/shm/raid-test LOOP=$(losetup --show -f /dev/shm/raid-test) dmsetup create raid-test-linear0 --table "0 1024 linear $LOOP 0" dmsetup create raid-test-linear1 --table "0 1024 linear $LOOP 1024" dmsetup create raid-test --table "0 1024 raid raid1 1 2048 2 - /dev/mapper/raid-test-linear0 - /dev/mapper/raid-test-linear1" This results in the following crash: [ 4029.110216] device-mapper: raid: Ignoring chunk size parameter for RAID 1 [ 4029.110217] device-mapper: raid: Choosing default region size of 4MiB [ 4029.111349] md/raid1:mdX: active with 2 out of 2 mirrors [ 4029.114770] BUG: unable to handle kernel NULL pointer dereference at 0000000000000030 [ 4029.114802] IP: bitmap_resize+0x25/0x7c0 [md_mod] [ 4029.114816] PGD 0 … [ 4029.115059] Hardware name: Aquarius Pro P30 S85 BUY-866/B85M-E, BIOS 2304 05/25/2015 [ 4029.115079] task: ffff88015cc29a80 task.stack: ffffc90001a5c000 [ 4029.115097] RIP: 0010:bitmap_resize+0x25/0x7c0 [md_mod] [ 4029.115112] RSP: 0018:ffffc90001a5fb68 EFLAGS: 00010246 [ 4029.115127] RAX: 0000000000000005 RBX: 0000000000000000 RCX: 0000000000000000 [ 4029.115146] RDX: 0000000000000000 RSI: 0000000000000400 RDI: 0000000000000000 [ 4029.115166] RBP: ffffc90001a5fc28 R08: 0000000800000000 R09: 00000008ffffffff [ 4029.115185] R10: ffffea0005661600 R11: ffff88015cc29a80 R12: ffff88021231f058 [ 4029.115204] R13: 0000000000000000 R14: 0000000000000000 R15: 0000000000000000 [ 4029.115223] FS: 00007fe73a6b4740(0000) GS:ffff88021ea80000(0000) knlGS:0000000000000000 [ 4029.115245] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 4029.115261] CR2: 0000000000000030 CR3: 0000000159a74000 CR4: 00000000001426e0 [ 4029.115281] Call Trace: [ 4029.115291] ? raid_iterate_devices+0x63/0x80 [dm_raid] [ 4029.115309] ? dm_table_all_devices_attribute.isra.23+0x41/0x70 [dm_mod] [ 4029.115329] ? dm_table_set_restrictions+0x225/0x2d0 [dm_mod] [ 4029.115346] raid_preresume+0x81/0x2e0 [dm_raid] [ 4029.115361] dm_table_resume_targets+0x47/0xe0 [dm_mod] [ 4029.115378] dm_resume+0xa8/0xd0 [dm_mod] [ 4029.115391] dev_suspend+0x123/0x250 [dm_mod] [ 4029.115405] ? table_load+0x350/0x350 [dm_mod] [ 4029.115419] ctl_ioctl+0x1c2/0x490 [dm_mod] [ 4029.115433] dm_ctl_ioctl+0xe/0x20 [dm_mod] [ 4029.115447] do_vfs_ioctl+0x8d/0x5a0 [ 4029.115459] ? ____fput+0x9/0x10 [ 4029.115470] ? task_work_run+0x79/0xa0 [ 4029.115481] SyS_ioctl+0x3c/0x70 [ 4029.115493] entry_SYSCALL_64_fastpath+0x13/0x94 The raid_preresume() function incorrectly assumes that the raid_set has a bitmap enabled if RT_FLAG_RS_BITMAP_LOADED is set. But RT_FLAG_RS_BITMAP_LOADED is getting set in __load_dirty_region_bitmap() even if there is no bitmap present (and bitmap_load() happily returns 0 even if a bitmap isn't present). So the only way forward in the near-term is to check if the bitmap is present by seeing if mddev->bitmap is not NULL after bitmap_load() has been called. By doing so the above NULL pointer is avoided.

2017-03-31irqchip/mips-gic: Fix Local compare interruptMatt Redfearn1-0/+4
Commit 4cfffcfa5106 ("irqchip/mips-gic: Fix local interrupts") added mapping of several local interrupts during initialisation of the gic driver. This associates virq numbers with these interrupts. Unfortunately, as not all of the interrupts are mapped in hardware order, when drivers subsequently request these interrupts they conflict with the mappings that have already been set up. For example, this manifests itself in the gic clocksource driver, which fails to probe with the message: clocksource: GIC: mask: 0xffffffffffffffff max_cycles: 0x7350c9738, max_idle_ns: 440795203769 ns GIC timer IRQ 25 setup failed: -22 This is because virq 25 (the correct IRQ number specified via device tree) was allocated to the PERFCTR interrupt (and 24 to the timer, 26 to the FDC). To fix this, map all of these local interrupts in the hardware order so as to associate their virq numbers with the correct hw interrupts.

2017-03-31drm/i915: Use a dummy timeline name for a signaled fenceChris Wilson1-0/+11
Michał Winiarski pointed out that the debugging infrastructure (such as trace_dma_fence_release) likes to pretty print the timeline name, long after we have freed the timeline. Our timelines currently live as part of the GTT (due to the strict ordering we currently use through each) which belong to the context. We aim to free the context and release its hardware resources as soon as we able to (i.e. when the last fence/request using it has been signaled and retired). As the .get_timeline_name is purely a debug feature, rather than extending the lifetime of the context, or splitting it into many different release phases just to keep the name around, replace the timeline name with a constant after the fence has been signaled. This avoids the potential use-after-free.

2017-03-31drm/i915: Avoid lock dropping between reschedulingChris Wilson1-29/+24
Unlocking is dangerous. In this case we combine an early update to the out-of-queue request, because we know that it will be inserted into the correct FIFO priority-ordered slot when it becomes ready in the future. However, given sufficient enthusiasm, it may become ready as we are continuing to reschedule, and so may gazump the FIFO if we have since dropped its spinlock. The result is that it may be executed too early, before its dependencies. v2: Move all work into the second phase over the topological sort. This removes the shortcut on the out-of-rbtree request to ensure that we only adjust its priority after adjusting all of its dependencies.

We found the pin 0x1a is assigned to lineout on this machine, and in the past, we applied ALC298_FIXUP_DELL1_MIC_NO_PRESENCE to fix the heaset-set mic problem for this machine, this fixup will redefine the pin 0x1a to headphone-mic, as a result the lineout doesn't work anymore.

MCA bank 3 is reserved on systems pre-Fam17h, so it didn't have a name. However, MCA bank 3 is defined on Fam17h systems and can be accessed using legacy MSRs. Without a name we get a stack trace on Fam17h systems when trying to register sysfs files for bank 3 on kernels that don't recognize Scalable MCA. Call MCA bank 3 "decode_unit" since this is what it represents on Fam17h. This will allow kernels without SMCA support to see this bank on Fam17h+ and prevent the stack trace. This will not affect older systems since this bank is reserved on them, i.e. it'll be ignored. Tested on AMD Fam15h and Fam17h systems.

2017-03-30target: Fix ALUA transition state race between multiple initiatorsMike Christie3-95/+51
Multiple threads could be writing to alua_access_state at the same time, or there could be multiple STPGs in flight (different initiators sending them or one initiator sending them to different ports), or a combo of both and the core_alua_do_transition_tg_pt calls will race with each other. Because from the last patches we no longer delay running core_alua_do_transition_tg_pt_work, there does not seem to be any point in running that in a workqueue. And, we always wait for it to complete one way or another, so we can sleep in this code path. So, this patch made over target-pending just adds a mutex and does the work core_alua_do_transition_tg_pt_work was doing in core_alua_do_transition_tg_pt. There is also no need to use an atomic for the tg_pt_gp_alua_access_state. In core_alua_do_transition_tg_pt we will test and set it under the transition mutex. And, it is a int/32 bits so in the other places where it is read, we will never see it partially updated.

2017-03-30iser-target: Fix queue-full response handlingNicholas Bellinger1-18/+35
This patch addresses two queue-full handling bugs in iser-target. The first is propagating isert_rdma_rw_ctx_post() return back to target-core via isert_put_datain() + isert_get_dataout() callbacks, in order to trigger queue-full logic in target-core. Note target-core expects -EAGAIN or -ENOMEM error to signal RDMA WRITE/READ data-transfer callbacks should be retried, after queue-full logic been invoked. Other types of errors propagated up from RDMA RW API will result in target-core generating internal CHECK_CONDITION status, avoiding subsequent isert_put_datain() and isert_get_dataout() iscsit_transport callback retry attempts. The second is to use transport_generic_request_failure() during T10-PI hw-offload errors in isert_rdma_write_done() and isert_rdma_read_done(), so CHECK_CONDITION queue-full is handled internally by target-core. Also add isert_put_response() T10-PI failure case fixme in isert_rdma_write_done(), which is currently not internally retried or released until session reinstatement.

This patch fixes a set of queue-full response handling bugs, where outgoing responses are leaked when a fabric driver is propagating non -EAGAIN or -ENOMEM errors to target-core. It introduces TRANSPORT_COMPLETE_QF_ERR state used to signal when CHECK_CONDITION status should be generated, when fabric driver ->write_pending(), ->queue_data_in(), or ->queue_status() callbacks fail with non -EAGAIN or -ENOMEM errors, and data-transfer should not be retried. Note all fabric driver -EAGAIN and -ENOMEM errors are still retried indefinately with associated data-transfer callbacks, following existing queue-full logic. Also fix two missing ->queue_status() queue-full cases related to CMD_T_ABORTED w/ TAS status handling.

2017-03-30xtensa: make __pa work with uncached KSEG addressesMax Filippov1-0/+13
When __pa is applied to virtual address in uncached KSEG region the result is incorrect. Fix it by checking if the original address is in the uncached KSEG and adjusting the result. It looks better than masking off bits because pfn_valid would correctly work with new __pa results and it may be made working in noMMU case, once we get definition for uncached memory view. This is required for the dma_common_mmap and DMA debug code to work correctly: they both indirectly use __pa with coherent DMA addresses. In case of DMA debug the visible effect is false reports that an address mapped for DMA is accessed by CPU.

git://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi-fixes iwlwifi fixes for 4.11 Here are three patches intended for 4.11. The first one is an RCU fix by Sari. The second one is a fix for a potential out-of-bounds access crash by Dan. And finally, the third and bigger one, is a fix for IBSS, which has been broken since DQA was enabled in the driver.
2017-03-30arm64: fix NULL dereference in have_cpu_die()Mark Salter1-1/+1
Commit 5c492c3f5255 ("arm64: smp: Add function to determine if cpus are stuck in the kernel") added a helper function to determine if die() is supported in cpu_ops. This function assumes a cpu will have a valid cpu_ops entry, but that may not be the case for cpu0 is spin-table or parking protocol is used to boot secondary cpus. In that case, there is a NULL dereference if have_cpu_die() is called by cpu0. So add a check for a valid cpu_ops before dereferencing it.

2017-03-30ARM: orion5x: only call into phylib when availableArnd Bergmann2-0/+6
Board code cannot call mdiobus_register_board_info() when phylib or mdio_device is a loadable module: arch/arm/plat-orion/common.o: In function `orion_ge00_switch_init': :(.init.text+0x474): undefined reference to `mdiobus_register_board_info' I had a number of ideas for how this could be solved, but after the MDIO code got split out from PHYLIB it has gotten too hard, so I'm basically giving up, and only call the mdiobus_register_board_info() function if the MDIO layer is built-in to avoid the link error. This is similar to how we handle PHY registration on other ARM platforms.
