- Summary
- RDMA/irdma: Replace waitqueue and flag with completion
- Details
-
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 hanguidong02@gmail.com 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.
