2020-01-10Input: pegasus_notetaker - fix endpoint sanity checkJohan Hovold
The driver was checking the number of endpoints of the first alternate setting instead of the current one, something which could be used by a malicious device (or USB descriptor fuzzer) to trigger a NULL-pointer dereference.

2020-01-10Input: evdev - convert kzalloc()/vzalloc() to kvzalloc()Miles Chen
We observed a large(order-3) allocation in evdev_open() and it may cause an OOM kernel panic in kzalloc(), before we getting to the vzalloc() fallback. Fix it by converting kzalloc()/vzalloc() to kvzalloc() to avoid the OOM killer logic as we have a vmalloc fallback.

2020-01-10platform/x86: GPD pocket fan: Use default values when wrong modparams are givenHans de Goede
Use our default values when wrong module-parameters are given, instead of refusing to load. Refusing to load leaves the fan at the BIOS default setting, which is "Off". The CPU's thermal throttling should protect the system from damage, but not-loading is really not the best fallback in this case. This commit fixes this by re-setting module-parameter values to their defaults if they are out of range, instead of failing the probe with -EINVAL.

2020-01-10platform/mellanox: fix potential deadlock in the tmfifo driverLiming Sun
This commit fixes the potential deadlock caused by the console Rx and Tx processing at the same time. Rx and Tx both take the console and tmfifo spinlock but in different order which causes potential deadlock. The fix is to use different tmfifo spinlock for Rx and Tx since they protect different resources and it's safe to split the lock. Below is the reported call trace when copying/pasting large string in the console.

2020-01-10scsi: enclosure: Fix stale device oops with hot replugJames Bottomley
Doing an add/remove/add on a SCSI device in an enclosure leads to an oops caused by poisoned values in the enclosure device list pointers. The reason is because we are keeping the enclosure device across the enclosed device add/remove/add but the current code is doing a device_add/device_del/device_add on it. This is the wrong thing to do in sysfs, so fix it by not doing a device_del on the enclosure device simply because of a hot remove of the drive in the slot.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2020-01-09 This series contains fixes to e1000e, igb, ixgbe, ixgbevf, i40e and iavf drivers. Brett fixes the validation of the virtchnl queue select bitmaps by comparing the bitmaps against BIT(I40E_MAX_VF_QUEUES). Radoslaw removes the limitation of only 10 filter entries for a VF and allows use of all free RAR entries for the forwarding database, if needed. Cambda Zhu fixes the calculation of queue when restoring flow director filters after resetting the adapter for ixgbe. Manfred Rudigier fixes the SGMIISFP module discovery for 100FX/LX modules for igb. Stefan Assmann fixes iavf where during a VF reset event, MAC filters were not altered, which could lead to a stale filter when an administratively set MAC address is forced by the PF. Adam adds the missing code to set the PHY access flag on X722 devices, which supports accessing PHY registers with the admin queue command. Revert a previous commit for e1000e to use "delayed work" which was causing connections to reset unexpectedly and possible driver crashes. ==================== Signed-off-by: David S.

2020-01-09i2c: fix bus recovery stop mode timingRussell King
The I2C specification states that tsu:sto for standard mode timing must be at minimum 4us. Pictographically, this is: SCL: ____/~~~~~~~~~ SDA: _________/~~~~ ->| |<- 4us minimum We are currently waiting 2.5us between asserting SCL and SDA, which is in violation of the standard. Adjust the timings to ensure that we meet what is stipulated as the minimum timings to ensure that all devices correctly interpret the STOP bus transition. This is more important than trying to generate a square wave with even duty cycle. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2020-01-09mtd: spi-nor: Fix the writing of the Status Register on micron flashesTudor Ambarus
Micron flashes do not support 16 bit writes on the Status Register. According to micron datasheets, when using the Write Status Register (01h) command, the chip select should be driven LOW and held LOW until the eighth bit of the last data byte has been latched in, after which it must be driven HIGH. If CS is not driven HIGH, the command is not executed, flag status register error bits are not set, and the write enable latch remains set to 1. This fixes the lock operations on micron flashes.
