This approach offers more granular capabilities than the existing Linux capabilities, which may be too generic for certain FW features. This mechanism represents each capability as a character device with root read-write access. Root processes can grant users special privileges by allowing access to these character devices (e.g., using chown). UCAP character devices are located in /dev/infiniband and the class path is /sys/class/infiniband_ucaps.
