We need to open a file to restore a file mapping and this file can be from a current mntns. v2: All namespaces are resotred from the root task and then other tasks calls setns() to set a proper mntns. v3: fix comments from Pavel Signed-off-by:

There might be several same terminals opened (say tty6 or whatever) which gonna look as separate files but actually pointing to the same tty kernel instance. Moreover if it's a controlling terminal we will be trying to restore it as many times as find non zero sid on a peer. Instead lets do a simple trick first: choose a leader from a terminal group and use it only for controlling terminal restoration. https://jira.sw.ru/browse/PSBM-40969Signed-off-by:

open_mountpoint() have to operate in target's mount namespace, which may differ from root's namespace - root_item->pid.real. So obtain the correct mount namespace from mount_info and use it in switch_ns(). Signed-off-by:

If the pagemap we read at some point covers two (or more) pagemaps in parent images, we cannot just call the parent page read for all those pages. Instead, we must call parent page read with shorter requests so that it handles its own pagemaps properly. Signed-off-by: -

When the VMA being restored is not COW-ed we read pages from images one-by-one which results in suboptimal pages.img access. Fix this by reading as many pages from iamge at once as possible withing the active pagemap and VMA. Signed-off-by: -

In order to restore seccomp filters, we need to have access to dynamically allocated memory from the restorer blob, so we should unmap this memory afterwards. In order to do this, we need to suspend seccomp earlier, right after we attach to the tasks instead of just before we do the unmap of the restorer blob itself. Signed-off-by:
