QKEY Mitigation in the Kernel

QKEY creation with the MSB set is available now for non-privileged users as well.

To allow non-privileged users to create QKEY with MSB set, the below new module parameter was added to ib_uverbs module:

  • Module Parameter: enforce_qkey_check

  • Description: Force QKEY MSB check for non-privileged user on UD QP creation

  • Default: 0 (disabled)

Note: In this release, this module parameter is disabled by default to ensure backward compatibility and give customers the opportunity to update their applications accordingly. In the upcoming release, it will be enabled by default, and later on deprecated.
