2018-09-06drbd: Convert from ahash to shashKees Cook5-88/+76
In preparing to remove all stack VLA usage from the kernel[1], this removes the discouraged use of AHASH_REQUEST_ON_STACK in favor of the smaller SHASH_DESC_ON_STACK by converting from ahash-wrapped-shash to direct shash. By removing a layer of indirection this both improves performance and reduces stack usage. The stack allocation will be made a fixed size in a later patch to the crypto subsystem. The bulk of the lines in this change are simple s/ahash/shash/, but the main logic differences are in drbd_csum_ee() and drbd_csum_bio(), which externalizes the page walking with k(un)map_atomic() instead of using scattergather.

2018-09-03bnxt_en: Do not adjust max_cp_rings by the ones used by RDMA.Michael Chan4-12/+9
Currently, the driver adjusts the bp->hw_resc.max_cp_rings by the number of MSIX vectors used by RDMA. There is one code path in open that needs to check the true max_cp_rings including any used by RDMA. This code is now checking for the reduced max_cp_rings which will fail when the number of cp rings is very small. To fix this in a clean way, we don't adjust max_cp_rings anymore. Instead, we add a helper bnxt_get_max_func_cp_rings_for_en() to get the reduced max_cp_rings when appropriate. Fixes: ec86f14ea506 ("bnxt_en: Add ULP calls to stop and restart IRQs.")

We also need to signal the RDMA driver to stop and clear its interrupts. We then call the RoCE driver to restart if a new set of default rings is successfully reserved.

2018-09-02net: ethernet: cpsw-phy-sel: prefer phandle for phy selTony Lindgren1-3/+6
The cpsw-phy-sel device is not a child of the cpsw interconnect target module. It lives in the system control module. Let's fix this issue by trying to use cpsw-phy-sel phandle first if it exists and if not fall back to current usage of trying to find the cpsw-phy-sel child. That way the phy sel driver can be a child of the system control module where it belongs in the device tree. Without this fix, we cannot have a proper interconnect target module hierarchy in device tree for things like genpd. Note that deferred probe is mostly not supported by cpsw and this patch does not attempt to fix that. In case deferred probe support is needed, this could be added to cpsw_slave_open() and phy_connect() so they start handling and returning errors. For documenting it, looks like the cpsw-phy-sel is used for all cpsw device tree nodes. It's missing the related binding documentation, so let's also update the binding documentation accordingly.

2018-09-02of/platform: initialise AMBA default DMA masksLinus Walleij1-0/+4
This addresses a v4.19-rc1 regression in the PL111 DRM driver in drivers/gpu/pl111/* The driver uses the CMA KMS helpers and will thus at some point call down to dma_alloc_attrs() to allocate a chunk of contigous DMA memory for the framebuffer. It appears that in v4.18, it was OK that this (and other DMA mastering AMBA devices) left dev->coherent_dma_mask blank (zero). In v4.19-rc1 the WARN_ON_ONCE(dev && !dev->coherent_dma_mask) in dma_alloc_attrs() in include/linux/dma-mapping.h is triggered. The allocation later fails when get_coherent_dma_mask() is called from __dma_alloc() and __dma_alloc() returns NULL: drm-clcd-pl111 dev:20: coherent DMA mask is unset drm-clcd-pl111 dev:20: [drm:drm_fb_helper_fbdev_setup] *ERROR* Failed to set fbdev configuration It turns out that in commit 4d8bde883bfb ("OF: Don't set default coherent DMA mask") the OF core stops setting the default DMA mask on new devices, especially those lines of the patch: - if (!dev->coherent_dma_mask) - dev->coherent_dma_mask = DMA_BIT_MASK(32); Robin Murphy solved a similar problem in a5516219b102 ("of/platform: Initialise default DMA masks") by simply assigning dev.coherent_dma_mask and the dev.dma_mask to point to the same when creating devices from the device tree, and introducing the same code into the code path creating AMBA/PrimeCell devices solved my problem, graphics now come up. The code simply assumes that the device can access all of the system memory by setting the coherent DMA mask to 0xffffffff when creating a device from the device tree, which is crude, but seems to be what kernel v4.18 assumed. The AMBA PrimeCells do not differ between coherent and streaming DMA so we can just assign the same to any DMA mask. Possibly drivers should augment their coherent DMA mask in accordance with "dma-ranges" from the device tree if more finegranular masking is needed.

These are the related 3 paths which show the deadlock: path #1: Workqueue: hv_vmbus_con vmbus_onmessage_work [hv_vmbus] Call Trace: schedule schedule_preempt_disabled __mutex_lock __device_attach bus_probe_device device_add vmbus_device_register vmbus_onoffer vmbus_onmessage_work process_one_work worker_thread kthread ret_from_fork path #2: schedule schedule_preempt_disabled __mutex_lock netvsc_probe vmbus_probe really_probe __driver_attach bus_for_each_dev driver_attach_async async_run_entry_fn process_one_work worker_thread kthread ret_from_fork path #3: Workqueue: events netvsc_subchan_work [hv_netvsc] Call Trace: schedule rndis_set_subchannel netvsc_subchan_work process_one_work worker_thread kthread ret_from_fork Before path #1 finishes, path #2 can start to run, because just before the "bus_probe_device(dev);" in device_add() in path #1, there is a line "object_uevent(&dev->kobj, KOBJ_ADD);", so systemd-udevd can immediately try to load hv_netvsc and hence path #2 can start to run. Next, path #2 offloads the subchannal's initialization to a workqueue, i.e. path #3, so we can end up in a deadlock situation like this: Path #2 gets the device lock, and is trying to get the rtnl lock; Path #3 gets the rtnl lock and is waiting for all the subchannel messages to be processed; Path #1 is trying to get the device lock, but since #2 is not releasing the device lock, path #1 has to sleep; since the VMBus messages are processed one by one, this means the sub-channel messages can't be procedded, so #3 has to sleep with the rtnl lock held, and finally #2 has to sleep... Now all the 3 paths are sleeping and we hit the deadlock. With the patch, we can make sure #2 gets both the device lock and the rtnl lock together, gets its job done, and releases the locks, so #1 and #3 will not be blocked for ever.

2018-08-31nfp: wait for posted reconfigs when disabling the deviceJakub Kicinski1-15/+33
To avoid leaking a running timer we need to wait for the posted reconfigs after netdev is unregistered. In common case the process of deinitializing the device will perform synchronous reconfigs which wait for posted requests, but especially with VXLAN ports being actively added and removed there can be a race condition leaving a timer running after adapter structure is freed leading to a crash. Add an explicit flush after deregistering and for a good measure a warning to check if timer is running just before structures are freed.

2018-08-31gpio: Fix crash due to registration raceVincent Whitchurch1-0/+1
gpiochip_add_data_with_key() adds the gpiochip to the gpio_devices list before of_gpiochip_add() is called, but it's only the latter which sets the ->of_xlate function pointer. gpiochip_find() can be called by someone else between these two actions, and it can find the chip and call of_gpiochip_match_node_and_xlate() which leads to the following crash due to a NULL ->of_xlate().

This works since the driver looking for the gpio will simply fail to find the gpio and defer its probe and be reprobed when the driver which is registering the gpiochip has fully completed its probe.

2018-08-30i2c: designware: Re-init controllers with pm_disabled set on resumeHans de Goede2-2/+6
On Bay Trail and Cherry Trail devices we set the pm_disabled flag for I2C busses which the OS shares with the PUNIT as these need special handling. Until now we called dev_pm_syscore_device(dev, true) for I2C controllers with this flag set to keep these I2C controllers always on. After commit 12864ff8545f ("ACPI / LPSS: Avoid PM quirks on suspend and resume from hibernation"), this no longer works. This commit modifies lpss_iosf_exit_d3_state() to only run if lpss_iosf_enter_d3_state() has ran before it, so that it does not run on a resume from hibernate (or from S3). On these systems the conditions for lpss_iosf_enter_d3_state() to run never become true, so lpss_iosf_exit_d3_state() never gets called and the 2 LPSS DMA controllers never get forced into D0 mode, instead they are left in their default automatic power-on when needed mode. The not forcing of D0 mode for the DMA controllers enables these systems to properly enter S0ix modes, which is a good thing. But after entering S0ix modes the I2C controller connected to the PMIC no longer works, leading to e.g. broken battery monitoring. The _PS3 method for this I2C controller looks like this: Method (_PS3, 0, NotSerialized) // _PS3: Power State 3 { If ((((PMID == 0x04) || (PMID == 0x05)) || (PMID == 0x06))) { Return (Zero) } PSAT |= 0x03 Local0 = PSAT /* \_SB_.I2C5.PSAT */ } Where PMID = 0x05, so we enter the Return (Zero) path on these systems. So even if we were to not call dev_pm_syscore_device(dev, true) the I2C controller will be left in D0 rather then be switched to D3. Yet on other Bay and Cherry Trail devices S0ix is not entered unless *all* I2C controllers are in D3 mode. This combined with the I2C controller no longer working now that we reach S0ix states on these systems leads to me believing that the PUNIT itself puts the I2C controller in D3 when all other conditions for entering S0ix states are true. Since now the I2C controller is put in D3 over a suspend/resume we must re-initialize it afterwards and that does indeed fix it no longer working. This commit implements this fix by: 1) Making the suspend_late callback a no-op if pm_disabled is set and making the resume_early callback skip the clock re-enable (since it now was not disabled) while still doing the necessary I2C controller re-init. 2) Removing the dev_pm_syscore_device(dev, true) call, so that the suspend and resume callbacks are actually called. Normally this would cause the ACPI pm code to call _PS3 putting the I2C controller in D3, wreaking havoc since it is shared with the PUNIT, but in this special case the _PS3 method is a no-op so we can safely allow a "fake" suspend / resume.

2018-08-30i2c: i801: Allow ACPI AML access I/O ports not reserved for SMBusMika Westerberg1-1/+8
Commit 7ae81952cda ("i2c: i801: Allow ACPI SystemIO OpRegion to conflict with PCI BAR") made it possible for AML code to access SMBus I/O ports by installing custom SystemIO OpRegion handler and blocking i80i driver access upon first AML read/write to this OpRegion. However, while ThinkPad T560 does have SystemIO OpRegion declared under the SMBus device, it does not access any of the SMBus registers: Device (SMBU) { ... OperationRegion (SMBP, PCI_Config, 0x50, 0x04) Field (SMBP, DWordAcc, NoLock, Preserve) { , 5, TCOB, 11, Offset (0x04) } Name (TCBV, 0x00) Method (TCBS, 0, NotSerialized) { If ((TCBV == 0x00)) { TCBV = (\_SB.PCI0.SMBU.TCOB << 0x05) } Return (TCBV) /* \_SB_.PCI0.SMBU.TCBV */ } OperationRegion (TCBA, SystemIO, TCBS (), 0x10) Field (TCBA, ByteAcc, NoLock, Preserve) { Offset (0x04), , 9, CPSC, 1 } } Problem with the current approach is that it blocks all I/O port access and because this system has touchpad connected to the SMBus controller after first AML access (happens during suspend/resume cycle) the touchpad fails to work anymore. Fix this so that we allow ACPI AML I/O port access if it does not touch the region reserved for the SMBus.
