![]() We validated resync_after dependencies, if changed via disk-options. But we did not validate them when first created via attach. We also did not check or cleanup dependencies that used to be correct, but now point to meanwhile removed minor devices. If the drbd_resync_after_valid() validation in disk-options tried to follow a dependency chain in this way, this could lead to NULL pointer dereference. Validate resync_after settings in drbd_adm_attach() already, as well as in drbd_adm_disk_opts(), and and only reject dependency loops. Depending on non-existing disks is allowed and equivalent to no dependency.
