Following is the next version of the credentials c/r patchset, on top of the c/r patchset at git://git.ncl.cs.columbia.edu/pub/git/linux-cr.git It implements checkpoint and restart of user, user namespaces, groups, supplementary groups, and struct cred. There is a question as to what to do about LSM data at restart. Right now I'm ignoring it, which means that prepare_creds() should ensure that the restart tasks get the context of the task calling sys_restart(). I suspect the right thing to do is to add two new LSM hooks, one which checks current's authorization to restart from the checkpoint file, and one which determines the task->cred->security filed based upon any of: 1. current_security() of the task calling sys_restart() 2. the task->cred->security checkpointed in the ckpt file 3. the ->security of the checkpoint file Oren, I think this version has all the changes you asked for except for restoring cred info for sysvipc. thanks, -serge _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
