2020-08-07mm, treewide: rename kzfree() to kfree_sensitive()Waiman Long3-3/+3
As said by Linus: A symmetric naming is only helpful if it implies symmetries in use. Otherwise it's actively misleading. In "kzalloc()", the z is meaningful and an important part of what the caller wants. In "kzfree()", the z is actively detrimental, because maybe in the future we really _might_ want to use that "memfill(0xdeadbeef)" or something. The "zero" part of the interface isn't even _relevant_. The main reason that kzfree() exists is to clear sensitive information that should not be leaked to other future users of the same memory objects. Rename kzfree() to kfree_sensitive() to follow the example of the recently added kvfree_sensitive() and make the intention of the API more explicit. In addition, memzero_explicit() is used to clear the memory to make sure that it won't get optimized away by the compiler. The renaming is done by using the command sequence: git grep -w --name-only kzfree |\ xargs sed -i 's/kzfree/kfree_sensitive/' followed by some editing of the kfree_sensitive() kerneldoc and adding a kzfree backward compatibility macro in slab.h.

2020-08-06media: allegro: fix potential null dereference on headerColin Ian King1-2/+1
The pointer header is an alias to msg and msg is being null checked. However, if msg is null then header is also null and this can lead to a null pointer dereference on the assignment type = header->type. Fix this just using header->type after the null check and removing the need for type as it is only used once.

2020-07-31staging: android: ashmem: Fix lockdep warning for write operationSuren Baghdasaryan1-0/+12
syzbot report [1] describes a deadlock when write operation against an ashmem fd executed at the time when ashmem is shrinking its cache results in the following lock sequence: Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock(fs_reclaim); lock(&sb->s_type->i_mutex_key#13); lock(fs_reclaim); lock(&sb->s_type->i_mutex_key#13); kswapd takes fs_reclaim and then inode_lock while generic_perform_write takes inode_lock and then fs_reclaim. However ashmem does not support writing into backing shmem with a write syscall. The only way to change its content is to mmap it and operate on mapped memory. Therefore the race that lockdep is warning about is not valid. Resolve this by introducing a separate lockdep class for the backing shmem inodes.

Currently you can't enable the Gey Bus Audio Codec because there is no entry for it in the Kconfig file. Originally the config name was going to be AUDIO_MSM8994 but that's not correct because other types of hardware are supported now. I have chosen the name AUDIO_APB_CODEC instead. Also I had to update the dependencies for GREYBUS_AUDIO to make the compile work.

2020-07-29staging: sm750fb: use generic power managementVaibhav Gupta1-74/+17
Drivers using legacy power management .suspen()/.resume() callbacks have to manage PCI states and device's PM states themselves. They also need to take care of standard configuration registers. Switch to generic power management framework using a single "struct dev_pm_ops" variable to take the unnecessary load from the driver. This also avoids the need for the driver to directly call most of the PCI helper functions and device power state control functions, as through the generic framework PCI Core takes care of the necessary operations, and drivers are required to do only device-specific jobs.

One serious bug was fixed by 9d32c0cde4e2 ("staging/speakup: fix get_word non-space look-ahead"), which does not seem to really be related to the bug mentioned in TODO.
