Staging: rtl8723bs: fix an error code in isFileReadable()

2017-06-14T10:43:54Z

The caller only cares about zero vs non-zero so this code actually works fine but we should be returning a negative error code instead of a valid pointer casted to int. Fixes: 554c0a3abf21 ("staging: Add rtl8723bs sdio wifi driver") Signed-off-by: Dan Carpenter Signed-off-by: Greg Kroah-Hartman

Jonathan writes: Second set of IIO fixes for the 4.12 cycle. * buffer-dma / buffer-dmaengine - Fix missing include of buffer_impl.h after the split of buffer.h. No driver in mainline is currently using these buffers so it wasn't picked up by automated build tests. * ad7152 - Fix a deadlock in ad7152_write_raw_samp_freq as the chip_state lock was already held. * inv_mpu6050 - Add low pass filter setting for chips newer than the MPU6500. None of use previously picked up no the fact it was different on these newer chips. It is separately set for the acceleration on these parts. There is no normal reason to set it differently so the userspace interface remains the same as for early parts. * meson-saradc: - Fix a potential crash by NULL pointer dereference in meson_sar_adc_clear_fifo. * mxs-lradc - Fix a return value check where IS_ERR is used on a function that returns NULL on error

net: Fix inconsistent teardown and release of private netdev state.

2017-06-07T19:53:24Z

Network devices can allocate reasources and private memory using netdev_ops->ndo_init(). However, the release of these resources can occur in one of two different places. Either netdev_ops->ndo_uninit() or netdev->destructor(). The decision of which operation frees the resources depends upon whether it is necessary for all netdev refs to be released before it is safe to perform the freeing. netdev_ops->ndo_uninit() presumably can occur right after the NETDEV_UNREGISTER notifier completes and the unicast and multicast address lists are flushed. netdev->destructor(), on the other hand, does not run until the netdev references all go away. Further complicating the situation is that netdev->destructor() almost universally does also a free_netdev(). This creates a problem for the logic in register_netdevice(). Because all callers of register_netdevice() manage the freeing of the netdev, and invoke free_netdev(dev) if register_netdevice() fails. If netdev_ops->ndo_init() succeeds, but something else fails inside of register_netdevice(), it does call ndo_ops->ndo_uninit(). But it is not able to invoke netdev->destructor(). This is because netdev->destructor() will do a free_netdev() and then the caller of register_netdevice() will do the same. However, this means that the resources that would normally be released by netdev->destructor() will not be. Over the years drivers have added local hacks to deal with this, by invoking their destructor parts by hand when register_netdevice() fails. Many drivers do not try to deal with this, and instead we have leaks. Let's close this hole by formalizing the distinction between what private things need to be freed up by netdev->destructor() and whether the driver needs unregister_netdevice() to perform the free_netdev(). netdev->priv_destructor() performs all actions to free up the private resources that used to be freed by netdev->destructor(), except for free_netdev(). netdev->needs_free_netdev is a boolean that indicates whether free_netdev() should be done at the end of unregister_netdevice(). Now, register_netdevice() can sanely release all resources after ndo_ops->ndo_init() succeeds, by invoking both ndo_ops->ndo_uninit() and netdev->priv_destructor(). And at the end of unregister_netdevice(), we invoke netdev->priv_destructor() and optionally call free_netdev(). Signed-off-by: David S. Miller

staging: ccree: fix buffer copy

2017-06-06T14:23:27Z

Fix a bug where the copying of scatterlist buffers incorrectly ignored bytes to skip in a scatterlist and ended 1 byte short. This fixes testmgr hmac and hash test failures currently obscured by hash import/export not being supported. Fixes: abefd6741d ("staging: ccree: introduce CryptoCell HW driver").

[media] atomisp: don't treat warnings as errors

2017-06-04T18:23:32Z

Several atomisp files use: ccflags-y += -Werror As, on media, our usual procedure is to use W=1, and atomisp has *a lot* of warnings with such flag enabled,like: ./drivers/staging/media/atomisp/pci/atomisp2/css2400/hive_isp_css_common/host/system_local.h:62:26: warning: 'DDR_BASE' defined but not used [-Wunused-const-variable=] At the end, it causes our build to fail, impacting our workflow. So, remove this crap. If one wants to force -Werror, he can still build with it enabled by passing a parameter to make. Signed-off-by: Mauro Carvalho Chehab

staging/lustre/lov: remove set_fs() call from lov_getstripe()

2017-06-03T08:17:19Z

lov_getstripe() calls set_fs(KERNEL_DS) so that it can handle a struct lov_user_md pointer from user- or kernel-space. This changes the behavior of copy_from_user() on SPARC and may result in a misaligned access exception which in turn oopses the kernel. In fact the relevant argument to lov_getstripe() is never called with a kernel-space pointer and so changing the address limits is unnecessary and so we remove the calls to save, set, and restore the address limits.
