While looking for kuid_t and kgid_t conversions I found this structure that has never been used since it was added to the kernel in 2007. The obvious for this structure to be used is in xdr_encode_AFS_StoreStatus and that function uses a small handful of local variables instead. So remove the unnecessary structure to prevent confusion.

There is no backing store to tmpfs and file creation rules are the same as for any other filesystem so it is semantically safe to allow unprivileged users to mount it. ramfs is safe for the same reasons so allow either flavor of tmpfs to be mounted by a user namespace root user.

When I initially wrote the code for /proc/<pid>/uid_map. I was lazy and avoided duplicate mappings by the simple expedient of ensuring the first number in a new extent was greater than any number in the previous extent. Unfortunately that precludes a number of valid mappings, and someone noticed and complained. So use a simple check to ensure that ranges in the mapping extents don't overlap.

When freeing a deeply nested user namespace free_user_ns calls put_user_ns on it's parent which may in turn call free_user_ns again. When -fno-optimize-sibling-calls is passed to gcc one stack frame per user namespace is left on the stack, potentially overflowing the kernel stack. CONFIG_FRAME_POINTER forces -fno-optimize-sibling-calls so we can't count on gcc to optimize this code. Remove struct kref and use a plain atomic_t. Making the code more flexible and easier to comprehend. Make the loop in free_user_ns explict to guarantee that the stack does not overflow with CONFIG_FRAME_POINTER enabled. I have tested this fix with a simple program that uses unshare to create a deeply nested user namespace structure and then calls exit. With 1000 nesteuser namespaces before this change running my test program causes the kernel to die a horrible death. With 10,000,000 nested user namespaces after this change my test program runs to completion and causes no harm.

Oleg pointed out that in a pid namespace the sequence. - pid 1 becomes a zombie - setns(thepidns), fork,... - reaping pid 1. - The injected processes exiting. Can lead to processes attempting access their child reaper and instead following a stale pointer. That waitpid for init can return before all of the processes in the pid namespace have exited is also unfortunate. Avoid these problems by disabling the allocation of new pids in a pid namespace when init dies, instead of when the last process in a pid namespace is reaped.

The sequence: unshare(CLONE_NEWPID) clone(CLONE_THREAD|CLONE_SIGHAND|CLONE_VM) Creates a new process in the new pid namespace without setting pid_ns->child_reaper.
