close_olds_fds() knows nothing about more than one set of service file descriptros, so it's better to call it before forking children as it was bedore 9d60724e ("restore: restore mntns before creating private vma-s") The root task restores all processes and pin them with file descriptors, then a task restores a mount namespace by opening the file descriptor of the root task via /proc/pid/fd/X.

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: -

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:
