Title

ftrace: Fix use-after-free for dynamic ftrace_ops

Summary

In the Linux kernel, the following vulnerability has been resolved: ftrace: Fix use-after-free for dynamic ftrace_ops KASAN reported a use-after-free with ftrace ops [1]. It was found from vmcore that perf had registered two ops with the same content successively, both dynamic. After unregistering the second ops, a use-after-free occurred. In ftrace_shutdown(), when the second ops is unregistered, the FTRACE_UPDATE_CALLS command is not set because there is another enabled ops with the same content. Also, both ops are dynamic and the ftrace callback function is ftrace_ops_list_func, so the FTRACE_UPDATE_TRACE_FUNC command will not be set. Eventually the value of 'command' will be 0 and ftrace_shutdown() will skip the rcu synchronization. However, ftrace may be activated. When the ops is released, another CPU may be accessing the ops. Add the missing synchronization to fix this problem.

After unregistering the second ops, a\nuse-after-free occurred.\n\nIn ftrace_shutdown(), when the second ops is unregistered, the\nFTRACE_UPDATE_CALLS command is not set because there is another enabled\nops with the same content.  Also, both ops are dynamic and the ftrace\ncallback function is ftrace_ops_list_func, so the\nFTRACE_UPDATE_TRACE_FUNC command will not be set. Eventually the value\nof \u0027command\u0027 will be 0 and ftrace_shutdown() will skip the rcu\nsynchronization.\n\nHowever, ftrace may be activated.
