Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ftrace: Fix softlockup in ftrace_module_enable<br /> <br /> A soft lockup was observed when loading amdgpu module.<br /> If a module has a lot of tracable functions, multiple calls<br /> to kallsyms_lookup can spend too much time in RCU critical<br /> section and with disabled preemption, causing kernel panic.<br /> This is the same issue that was fixed in<br /> commit d0b24b4e91fc ("ftrace: Prevent RCU stall on PREEMPT_VOLUNTARY<br /> kernels") and commit 42ea22e754ba ("ftrace: Add cond_resched() to<br /> ftrace_graph_set_hash()").<br /> <br /> Fix it the same way by adding cond_resched() in ftrace_module_enable.
