Modern kernels include:

 CAP_PERFMON = 38 (supported in upstream libcap-2.36)
 CAP_BPF = 39 (supported in upstream libcap-2.37)
 CAP_CHECKPOINT_RESTORE = 40 (supported in upstream libcap-2.43)

If your kernel supports the capability, but your build of libcap does not, you can work around this by specifying the numerical value of the capability instead. For example:

 sudo setcap cap_perfmon+ep foo

can be worked around as:

 sudo setcap 38=ep foo

At time of writing, upstream libcap is at version 2.66.
