vmalloc: fix remap_vmalloc_range() bounds checks

2020-04-29T14:33:14Z

commit bdebd6a2831b6fab69eb85cee74a8ba77f1a1cc2 upstream. remap_vmalloc_range() has had various issues with the bounds checks it promises to perform ("This function checks that addr is a valid vmalloc'ed area, and that it is big enough to cover the vma") over time, e.g.: - not detecting pgoff< Signed-off-by: Andrew Morton Cc: stable@vger.kernel.org Cc: Alexei Starovoitov Cc: Daniel Borkmann Cc: Martin KaFai Lau Cc: Song Liu Cc: Yonghong Song Cc: Andrii Nakryiko Cc: John Fastabend Cc: KP Singh Link: http://lkml.kernel.org/r/20200415222312.236431-1-jannh@google.com Signed-off-by: Linus Torvalds Signed-off-by: Greg Kroah-Hartman

vfio-mdev/mtty: Simplify interrupt generation

2019-08-19T19:28:57Z

While generating interrupt, mdev_state is already available for which interrupt is generated. Instead of doing indirect way from state->device->uuid-> to searching state linearly in linked list on every interrupt generation, directly use the available state. Hence, simplify the code to use mdev_state and remove unused helper function with that.

treewide: remove SPDX "WITH Linux-syscall-note" from kernel-space headers again

2019-07-25T09:05:10Z

The "WITH Linux-syscall-note" exception exists for headers exported to user space. It is strange to add it to non-exported headers. Commit 687a3e4d8e61 ("treewide: remove SPDX "WITH Linux-syscall-note" from kernel-space headers") did cleanups some months ago, but it looks like we need to do this periodically. This patch was generated by the following script: git grep -l -e Linux-syscall-note \ -- :*.h :^arch/*/include/uapi/asm/*.h :^include/uapi/ :^tools | while read file do sed -i -e 's/($GPL-[^[:space:]]*$ WITH Linux-syscall-note)/\1/g' \ -e 's/ WITH Linux-syscall-note//g' $file done I did not commit drivers/staging/android/uapi/ion.h . This header is not currently exported, but somebody may plan to move it to include/uapi/ when the time comes. I am not sure. Anyway, it will be better to check the license inconsistency in drivers/staging/android/uapi/. Signed-off-by: Masahiro Yamada Reviewed-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman
