Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> IB/rdmavt: add lock to call to rvt_error_qp to prevent a race condition<br /> <br /> The documentation of the function rvt_error_qp says both r_lock and s_lock<br /> need to be held when calling that function. It also asserts using lockdep<br /> that both of those locks are held. However, the commit I referenced in<br /> Fixes accidentally makes the call to rvt_error_qp in rvt_ruc_loopback no<br /> longer covered by r_lock. This results in the lockdep assertion failing<br /> and also possibly in a race condition.
