Michael Ellerman 3210f0ecdb Restore call_usermodehelper_pipe() behaviour ... The semantics of call_usermodehelper_pipe() used to be that it would fork the helper, and wait for the kernel thread to be started. This was implemented by setting sub_info.wait to 0 (implicitly), and doing a wait_for_completion(). As part of the cleanup done in 0ab4dc9227, call_usermodehelper_pipe() was changed to pass 1 as the value for wait to call_usermodehelper_exec(). This is equivalent to setting sub_info.wait to 1, which is a change from the previous behaviour. Using 1 instead of 0 causes __call_usermodehelper() to start the kernel thread running wait_for_helper(), rather than directly calling ____call_usermodehelper(). The end result is that the calling kernel code blocks until the user mode helper finishes. As the helper is expecting input on stdin, and now no one is writing anything, everything locks up (observed in do_coredump). The fix is to change the 1 to UMH_WAIT_EXEC (aka 0), indicating that we want to wait for the kernel thread to be started, but not for the helper to finish.
