remap: add remap_type field and use it Maintain backwards compatibility for old images, but don't set the REMAP_GHOST bit going forward, only use the remap_type field. v2: * preserve remap_id in GHOST_REMAP case * protobuf field is remap_type enum not u32 Signed-off-by: Tycho Andersen <tycho.andersen@canonical.com> Signed-off-by: Pavel Emelyanov <xemul@parallels.com> 2014-09-18 00:32:00 +04:00			`enum remap_type {`

remap: add a dead pid /proc remap If a file like /proc/20/mountinfo is open, but 20 is a zombie (or doesn't exist any more), we can't read this file at all, so a link remap won't work. Instead, we add a new remap, called the dead process remap, which forks a TASK_HELPER as that dead pid so that the restore task can open the new /proc/20/mountinfo instead. This commit also adds a new stage CR_STATE_RESTORE_SHARED. Since new TASK_HELPERS are added when loading the shared resource images, we need to wait to start forking tasks until after these resources are loaded. v2: fix a mutex bug Signed-off-by: Tycho Andersen <tycho.andersen@canonical.com> Signed-off-by: Pavel Emelyanov <xemul@parallels.com> 2014-09-17 15:32:17 -05:00			`PROCFS = 2;`
