2017-01-01net: socket: don't set sk_uid to garbage value in ->setattr()Eric Biggers
->setattr() was recently implemented for socket files to sync the socket inode's uid to the new 'sk_uid' member of struct sock. It does this by copying over the ia_uid member of struct iattr. However, ia_uid is actually only valid when ATTR_UID is set in ia_valid, indicating that the uid is being changed, e.g. by chown. Other metadata operations such as chmod or utimes leave ia_uid uninitialized. Therefore, sk_uid could be set to a "garbage" value from the stack. Fix this by only copying the uid over when ATTR_UID is set. Fixes: 86741ec25462 ("net: core: Add a UID field to struct sock.")

2016-12-31iio: accel: st_accel: fix LIS3LV02 reading and scalingLinus Walleij
The LIS3LV02 has a special bit that need to be set to get the read values left aligned. Before this patch we get gibberish like this: iio_generic_buffer -a -c10 -n lis3lv02dl_accel (...) 0.000000 -0.010042 -0.642688 19155832931907 0.000000 -0.010042 -0.642688 19155858751073 Which is because we read a raw value for 1g as 64 which is the nominal 1024 for 1g shifted 4 bits to the left by being right-aligned rather than left aligned. Since all other sensors are left aligned, add some code to set the special DAS (data alignment setting) bit to 1 so that the right value is now read like this: iio_generic_buffer -a -c10 -n lis3lv02dl_accel (...) 0.000000 -0.147095 -10.120135 24761614364956 -0.029419 -0.176514 -10.120135 24761631624540 The scaling was weird as well: we have a gain of 1000 for 1g and 3000 for 6g.

Attempting to link a device node, named pipe, or socket file into an encrypted directory through rename(2) or link(2) always failed with EPERM.

2016-12-30vfio-mdev: Fix remove raceAlex Williamson
Using the mtty mdev sample driver we can generate a remove race by starting one shell that continuously creates mtty devices and several other shells all attempting to remove devices, in my case four remove shells. The fault occurs in mdev_remove_sysfs_files() where the passed type arg is NULL, which suggests we've received a struct device in mdev_device_remove() but it's in some sort of teardown state. The solution here is to make use of the accidentally unused list_head on the mdev_device such that the mdev core keeps a list of all the mdev devices. This allows us to validate that we have a valid mdev before we start removal, remove it from the list to prevent others from working on it, and if the vendor driver refuses to remove, we can re-add it to the list.

For some paths, like vfio_pin_pages_remote(), we know we're only called from user context, so we can restore the lighter weight calls. In other cases, we're effectively already testing whether we're in the stored task context elsewhere, extend this vfio_lock_acct() as well.

2016-12-30crypto: aesni - Fix failure when built-in with modular pcbcHerbert Xu
If aesni is built-in but pcbc is built as a module, then aesni will fail completely because when it tries to register the pcbc variant of aes the pcbc template is not available. This patch fixes this by modifying the pcbc presence test so that if aesni is built-in then pcbc must also be built-in for it to be used by aesni.

2016-12-30gpio: Move freeing of GPIO hogs before numbing of the deviceGeert Uytterhoeven
When removing a gpiochip that uses GPIO hogging (e.g. by unloading the chip's DT overlay), a warning is printed: gpio gpiochip8: REMOVING GPIOCHIP WITH GPIOS STILL REQUESTED This happens because gpiochip_free_hogs() is called after the gdev->chip pointer is reset to NULL. Hence __gpiod_free() cannot determine the chip in use, and cannot clear flags nor call the optional chip-specific .free() callback. Move the call to gpiochip_free_hogs() up to fix this.

Building with an old toolchain, I ran into this warning: WARNING: vmlinux.o(.text+0x63eef0): Section mismatch in reference from the function mxs_gpio_probe() to the function .init.text:mxs_gpio_init_gc() Clearly the annotation is wrong, since the function is called from the non-init probe, so let's remove it.

2016-12-29net: ipv4: dst for local input routes should use l3mdev if relevantDavid Ahern
IPv4 output routes already use l3mdev device instead of loopback for dst's if it is applicable. Change local input routes to do the same. This fixes icmp responses for unreachable UDP ports which are directed to the wrong table after commit 9d1a6c4ea43e4 because local_input routes use the loopback device. Moving from ingress device to loopback loses the L3 domain causing responses based on the dst to get to lost.

Commit 7e7814180b33 ("signal: consolidate {TS,TLF}_RESTORE_SIGMASK code") introduced code with which the "restore sigmask" flag lives in task_struct instead of ti->flags. Let's use this optimization on parisc too. Signed-off-by: Helge Deller <deller@gmx.de>
