Jann Horn 5c16a16fcf sys: don't hold uts_sem while accessing userspace memory ... commit 42a0cc3478584d4d63f68f2f5af021ddbea771fa upstream. Holding uts_sem as a writer while accessing userspace memory allows a namespace admin to stall all processes that attempt to take uts_sem. Instead, move data through stack buffers and don't access userspace memory while uts_sem is held.
