Now that the debug hook dispatching code takes the triggering exception level into account, there's no need for the hooks themselves to poke around with user_mode(regs). Reviewed-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Will Deacon <will.deacon@arm.com>

Kprobes bypasses our debug hook registration code so that it doesn't get tangled up with recursive debug exceptions from things like lockdep: http://lists.infradead.org/pipermail/linux-arm-kernel/2015-February/324385.html However, since then, (a) the hook list has become RCU protected and (b) the kprobes hooks were found not to filter out exceptions from userspace correctly. On top of that, the step handler is invoked directly from single_step_handler(), which *does* use the debug hook list, so it's clearly not the end of the world. For now, have kprobes use the debug hook registration API like everybody else. We can revisit this in the future if this is found to limit coverage significantly.

Mixing kernel and user debug hooks together is highly error-prone as it relies on all of the hooks to figure out whether the exception came from kernel or user, and then to act accordingly. Make our debug hook code a little more robust by maintaining separate hook lists for user and kernel, with separate registration functions to force callers to be explicit about the exception levels that they care about.

Since the 'addr' parameter contains an UNKNOWN value for non-watchpoint debug exceptions, rename it to 'unused' for those hooks so we don't get tempted to use it in the future. Reviewed-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Will Deacon <will.deacon@arm.com>

If the initrd payload isn't completely accessible via the linear map, then we print a warning during boot and nobble the virtual address of the payload so that we ignore it later on. Unfortunately, since commit c756c592 ("arm64: Utilize phys_initrd_start/phys_initrd_size"), the virtual address isn't initialised until later anyway, so we need to nobble the size of the payload to ensure that we don't try to use it later on.

If userspace doesn't end the input with a newline (which can easily happen if the write happens from a C program that does write(fd, iface, strlen(iface))), we may end up including garbage from a previous, longer value in the device_name. For example # cat device_name # printf 'eth12' > device_name # cat device_name eth12 # printf 'eth3' > device_name # cat device_name eth32 I highly doubt anybody is relying on this behaviour, so switch to simply copying the bytes (we've already checked that size is < IFNAMSIZ) and unconditionally zero-terminate it; of course, we also still have to strip a trailing newline.

Pull IOMMU fixes from Joerg Roedel: - Fix a bug in the AMD IOMMU driver not handling exclusion ranges correctly. In fact the driver did not reserve these ranges for IOVA allocations, so that dma-handles could be allocated in an exclusion range, leading to data corruption. Exclusion ranges have not been used by any firmware up to now, so this issue remained undiscovered for quite some time. - Fix wrong warning messages that the IOMMU core code prints when it tries to allocate the default domain for an iommu group and the driver does not support any of the default domain types (like Intel VT-d). * tag 'iommu-fixes-v5.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: iommu/amd: Reserve exclusion range in iova-domain iommu: Don't print warning when IOMMU driver only supports unmanaged domains
