2018-12-19powerpc/uaccess: fix warning/error with access_ok()Christophe Leroy
With the following piece of code, the following compilation warning is encountered: if (_IOC_DIR(ioc) != _IOC_NONE) { int verify = _IOC_DIR(ioc) & _IOC_READ ? VERIFY_WRITE : VERIFY_READ; if (!access_ok(verify, ioarg, _IOC_SIZE(ioc))) { drivers/platform/test/dev.c: In function 'my_ioctl': drivers/platform/test/dev.c:219:7: warning: unused variable 'verify' [-Wunused-variable] int verify = _IOC_DIR(ioc) & _IOC_READ ? VERIFY_WRITE : VERIFY_READ; This patch fixes it by referencing 'type' in the macro allthough doing nothing with it.

2018-12-19usb: r8a66597: Fix a possible concurrency use-after-free bug in ↵Jia-Ju Bai
r8a66597_endpoint_disable() The function r8a66597_endpoint_disable() and r8a66597_urb_enqueue() may be concurrently executed. The two functions both access a possible shared variable "hep->hcpriv". This shared variable is freed by r8a66597_endpoint_disable() via the call path: r8a66597_endpoint_disable kfree(hep->hcpriv) (line 1995 in Linux-4.19) This variable is read by r8a66597_urb_enqueue() via the call path: r8a66597_urb_enqueue spin_lock_irqsave(&r8a66597->lock) init_pipe_info enable_r8a66597_pipe pipe = hep->hcpriv (line 802 in Linux-4.19) The read operation is protected by a spinlock, but the free operation is not protected by this spinlock, thus a concurrency use-after-free bug may occur. To fix this bug, the spin-lock and spin-unlock function calls in r8a66597_endpoint_disable() are moved to protect the free operation.

2018-12-19usb: typec: tcpm: Extend the matching rules on PPS APDO selectionKyle Tso
Current matching rules ensure that the voltage range of selected Source Capability is entirely within the range defined in one of the Sink Capabilities. This is reasonable but not practical because Sink may not support wide range of voltage when sinking power while Source could advertise its capabilities in relatively wider range. For example, a Source PDO advertising 3.3V-11V@3A (9V Prog of Fixed Nominal Voltage) will not be selected if the Sink requires 5V-12V@3A PPS power. However, the Sink could work well if the requested voltage range in RDOs is 5V-11V@3A. Currently accepted: |--------- source -----| |----------- sink ---------------| Currently not accepted: |--------- source -----| |----------- sink ---------------| |--------- source -----| |----------- sink ---------------| |--------- source -----------------| |------ sink -------| To improve the usability, change the matching rules to what listed below: a. The Source PDO is selectable if any portion of the voltage range overlaps one of the Sink PDO's voltage range. b. The maximum operational voltage will be the lower one between the selected Source PDO and the matching Sink PDO. c. The maximum power will be the maximum operational voltage times the maximum current defined in the selected Source PDO d. Select the Source PDO with the highest maximum power Signed-off-by: Kyle Tso <kyletso@google.com> Acked-by: Adam Thomson <Adam.Thomson.Opensource@diasemi.com> Reviewed-by: Heikki Krogerus <heikki.krogerus@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2018-12-18net/smc: fix TCP fallback socket releaseMyungho Jung
clcsock can be released while kernel_accept() references it in TCP listen worker. Also, clcsock needs to wake up before released if TCP fallback is used and the clcsock is blocked by accept. Add a lock to safely release clcsock and call kernel_sock_shutdown() to wake up clcsock from accept in smc_release().
