- Summary
- bnxt_en: Shutdown FW DMA in bnxt_shutdown()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
bnxten: Shutdown FW DMA in bnxtshutdown()
The netifclose() call in bnxtshutdown() only stops packet DMA. There may be FW DMA for trace logging (recently added) that will continue. If we kexec to a new kernel, the DMA will corrupt memory in the new kernel.
Add bnxthwrmfuncdrvunrgtr() to unregister the driver from the FW. This will stop the FW DMA. In case the call fails, call pcie_flr() to reset the function and stop the DMA.
