Do so as in user-namespace on mainstream kernel writing to file with suid bit set always cleares these bit, regardless to CAP_FSETID. (see in should_remove_suid plane capable() is used, and same in VZ7) Also we have an alternative to wait while several patches will get in MS kernel: [PATCH v4 0/7] Initial support for user namespace owned mounts https://lkml.org/lkml/2015/9/23/591 [PATCH v2 12/18] fs: Don't remove suid for CAP_FSETID in s_user_ns http://www.spinics.net/lists/linux-fsdevel/msg92533.html Got error while suspending/resuming file_attr test in VZ7CT: CT-102 criu# cat test/zdtm/live/static/file_attr.out 13:11:01.952: 30635: FAIL: file_attr.c:96: permissions have changed (errno = 11 (Resource temporarily unavailable)) https://jira.sw.ru/browse/PSBM-41401Signed-off-by:

Currently criu dump may hang indefinitely. E.g. in wait for task that blocked in vfork() or task could be in D state for some other reason. This patch adds time limit on collecting tasks during the dump operation. If collecting processes takes too long, the dump process will be terminated. Timeout is 5 seconds by default, but it could be changed via parameter. Signed-off-by:

Use 'goto err;' everywhere. Remove 'pstree_switch_state(root_item, TASK_ALIVE)' on error path as all collect_pstree() callers do this if collect_pstree() failed. Signed-off-by:

This patch brings add_to_string() and construct_string() helpers. They allow to create a string with variable amount of parameters in sprintf() manner, but supporting string allocation (and reallocation if necessary) v2: 1) Helpers were renamed to xstrcat() and xsprintf() respectively. 2) Added printf attributes to force compiler check Signed-off-by:

restore_creds uses prctl, so if we block this call in the seccomp filter test, it causes things to fail (hang actually, seems we have some unhandled error path here). Signed-off-by:
