2018-08-03media: omap3isp: fix unbalanced dma_iommu_mappingSuman Anna
[ Upstream commit b7e1e6859fbf60519fd82d7120cee106a6019512 ] The OMAP3 ISP driver manages its MMU mappings through the IOMMU-aware ARM DMA backend. The current code creates a dma_iommu_mapping and attaches this to the ISP device, but never detaches the mapping in either the probe failure paths or the driver remove path resulting in an unbalanced mapping refcount and a memory leak. Fix this properly.

2018-08-03serial: core: Make sure compiler barfs for 16-byte earlycon namesDouglas Anderson
[ Upstream commit c1c734cb1f54b062f7e67ffc9656d82f5b412b9c ] As part of bringup I ended up wanting to call an earlycon driver by a name that was exactly 16-bytes big, specifically "qcom_geni_serial". Unfortunately, when I tried this I found that things compiled just fine. They just didn't work. Specifically the compiler felt perfectly justified in initting the ".name" field of "struct earlycon_id" with the full 16-bytes and just skipping the '\0'. Needless to say, that behavior didn't seem ideal, but I guess someone must have allowed it for a reason. One way to fix this is to shorten the name field to 15 bytes and then add an extra byte after that nobody touches. This should always be initted to 0 and we're golden. There are, of course, other ways to fix this too. We could audit all the users of the "name" field and make them stop at both null termination or at 16 bytes. We could also just make the name field much bigger so that we're not likely to run into this. ...but both seem like we'll just hit the bug again.

2018-08-03ipconfig: Correctly initialise ic_nameserversChris Novakovic
[ Upstream commit 300eec7c0a2495f771709c7642aa15f7cc148b83 ] ic_nameservers, which stores the list of name servers discovered by ipconfig, is initialised (i.e. has all of its elements set to NONE, or 0xffffffff) by ic_nameservers_predef() in the following scenarios: - before the "ip=" and "nfsaddrs=" kernel command line parameters are parsed (in ip_auto_config_setup()); - before autoconfiguring via DHCP or BOOTP (in ic_bootp_init()), in order to clear any values that may have been set after parsing "ip=" or "nfsaddrs=" and are no longer needed. This means that ic_nameservers_predef() is not called when neither "ip=" nor "nfsaddrs=" is specified on the kernel command line. In this scenario, every element in ic_nameservers remains set to 0x00000000, which is indistinguishable from ANY and causes pnp_seq_show() to write the following (bogus) information to /proc/net/pnp: #MANUAL nameserver 0.0.0.0 nameserver 0.0.0.0 nameserver 0.0.0.0 This is potentially problematic for systems that blindly link /etc/resolv.conf to /proc/net/pnp. Ensure that ic_nameservers is also initialised when neither "ip=" nor "nfsaddrs=" are specified by calling ic_nameservers_predef() in ip_auto_config(), but only when ip_auto_config_setup() was not called earlier. This causes the following to be written to /proc/net/pnp, and is consistent with what gets written when ipconfig is configured manually but no name servers are specified on the kernel command line: #MANUAL Signed-off-by: Chris Novakovic <chris@chrisn.me.uk> Signed-off-by: David S.

2018-08-03arm64: defconfig: Enable Rockchip io-domain driverEnric Balletbo i Serra
[ Upstream commit 7c8b77f81552c2b0e5d9c560da70bc4149ce66a5 ] Heiko Stübner justified pretty well the change in commit e330eb86ba0b ("ARM: multi_v7_defconfig: enable Rockchip io-domain driver"). This change is also needed for arm64 rockchip boards, so, do the same for arm64. The io-domain driver is necessary to notify the soc about voltages changes happening on supplying regulators. Probably the most important user right now is the mmc tuning code, where the soc needs to get notified when the voltage is dropped to the 1.8V point. As this option is necessary to successfully tune UHS cards etc, it should get built in. Otherwise, tuning will fail with, dwmmc_rockchip fe320000.dwmmc: All phases bad! mmc0: tuning execution failed: -5 Signed-off-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> Acked-by: Robin Murphy <robin.murphy@arm.com> Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Sasha Levin <alexander.levin@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

[ Upstream commit 486e6661367b40f927aadbed73237693396cbf94 ] The use of stack Variable Length Arrays needs to be avoided, as they can be a vector for stack exhaustion, which can be both a runtime bug (kernel Oops) or a security flaw (overwriting memory beyond the stack). Also, in general, as code evolves it is easy to lose track of how big a VLA can get. Thus, we can end up having runtime failures that are hard to debug. As part of the directive[1] to remove all VLAs from the kernel, and build with -Wvla. Currently driver is using a VLA declared using the number of descriptors. This array is used to store integer values and is later used as an argument to `gpiod_set_array_value_cansleep()` This can be avoided by using `kmalloc_array()` to allocate memory for the array of integer values. Memory is free'd before return from function. >From the code it appears that it is safe to sleep so we can use GFP_KERNEL (based _cansleep() suffix of function `gpiod_set_array_value_cansleep()`.

[ Upstream commit 9899e4d3523faaef17c67141aa80ff2088f17871 ] In tw_chrdev_ioctl(), the length of the data buffer is firstly copied from the userspace pointer 'argp' and saved to the kernel object 'data_buffer_length'. Then a security check is performed on it to make sure that the length is not more than 'TW_MAX_IOCTL_SECTORS * 512'. Otherwise, an error code -EINVAL is returned. If the security check is passed, the entire ioctl command is copied again from the 'argp' pointer and saved to the kernel object 'tw_ioctl'. Then, various operations are performed on 'tw_ioctl' according to the 'cmd'. Given that the 'argp' pointer resides in userspace, a malicious userspace process can race to change the buffer length between the two copies. This way, the user can bypass the security check and inject invalid data buffer length. This can cause potential security issues in the following execution. This patch checks for capable(CAP_SYS_ADMIN) in tw_chrdev_open() to avoid the above issues.

[ Upstream commit 9c4a121e82634aa000a702c98cd6f05b27d6e186 ] Add support for the BCM43364 chipset via an SDIO interface, as used in e.g. the Murata 1FX module. The BCM43364 uses the same firmware as the BCM43430 (which is already included), the only difference is the omission of Bluetooth. However, the SDIO_ID for the BCM43364 is 02D0:A9A4, giving it a MODALIAS of sdio:c00v02D0dA9A4, which doesn't get recognised and hence doesn't load the brcmfmac module. Adding the 'A9A4' ID in the appropriate place triggers the brcmfmac driver to load, and then correctly use the firmware file 'brcmfmac43430-sdio.bin'.

2018-08-03HID: i2c-hid: check if device is there before really probingDmitry Torokhov
[ Upstream commit b3a81b6c4fc6730ac49e20d789a93c0faabafc98 ] On many Chromebooks touch devices are multi-sourced; the components are electrically compatible and one can be freely swapped for another without changing the OS image or firmware. To avoid bunch of scary messages when device is not actually present in the system let's try testing basic communication with it and if there is no response terminate probe early with -ENXIO.

2018-08-03powerpc/embedded6xx/hlwd-pic: Prevent interrupts from being handled by StarletJonathan Neuschäfer
[ Upstream commit 9dcb3df4281876731e4e8bff7940514d72375154 ] The interrupt controller inside the Wii's Hollywood chip is connected to two masters, the "Broadway" PowerPC and the "Starlet" ARM926, each with their own interrupt status and mask registers. When booting the Wii with mini[1], interrupts from the SD card controller (IRQ 7) are handled by the ARM, because mini provides SD access over IPC. Linux however can't currently use or disable this IPC service, so both sides try to handle IRQ 7 without coordination. Let's instead make sure that all interrupts that are unmasked on the PPC side are masked on the ARM side; this will also make sure that Linux can properly talk to the SD card controller (and potentially other devices). If access to a device through IPC is desired in the future, interrupts from that device should not be handled by Linux directly.

[ Upstream commit 7a47f20eb1fb8fa8d7a8fe3a4fd8c721f04c2174 ] The method struct drm_connector_helper_funcs::mode_valid is defined as returning an 'enum drm_mode_status' but the driver implementation for this method uses an 'int' for it. Fix this by using 'enum drm_mode_status' in the driver too.

[ Upstream commit 1cfc63b5ae60fe7e01773f38132f98d8b13a99a0 ] When waiting for a cacheline to change state in cmpwait, we may immediately wake-up the first time around the outer loop if the event register was already set (for example, because of the event stream). Avoid these spurious wakeups by explicitly clearing the event register before loading the cacheline and setting the exclusive monitor.
