Linux Linux — RDMA/irdma: Replace waitqueue and flag with completion
Description · from the CVE record
In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Replace waitqueue and flag with completion The driver previously used a waitqueue along with an explicit request_done flag, but without proper barriers around request_done. An earlier patch by Gui-Dong Han <[email protected]> attempted to fix this by adding the missing memory barriers. Rather than adding the barriers, this patch replaces the waitqueue+flag with a completion, which is designed for this exact purpose.
