[PATCH v1 8/8] virtio-mem: kdump mode to sanitize /proc/vmcore access

Although virtio-mem currently supports reading unplugged memory in the hypervisor, this will change in the future, indicated to the device via a new feature flag. We similarly sanitized /proc/kcore access recently. [1] Let's register a vmcore callback, to allow vmcore code to check if a PFN belong

[PATCH v1 7/8] virtio-mem: factor out hotplug specifics from virtio_mem_remove() into virtio_mem_deinit_hotplug()

[PATCH v1 4/8] proc/vmcore: convert oldmem_pfn_is_ram callback to more generic vmcore callbacks

Let's support multiple registered callbacks, making sure that registering vmcore callbacks cannot fail. Make the callback return a bool instead of an int, handling how to deal with errors internally. Drop unused HAVE_OLDMEM_PFN_IS_RAM. We soon want to make use of this infrastructure from other dri

[PATCH v1 3/8] proc/vmcore: let pfn_is_ram() return a bool

The callback should deal with errors internally, it doesn't make sense to expose these via pfn_is_ram(). We'll rework the callbacks next. Right now we consider errors as if "it's RAM"; no functional change. Signed-off-by: David Hildenbrand --- fs/proc/vmcore.c | 8 1 file changed, 4 ins
