tetragon: probe_read usage may cause issues with newer kernels #2925

Closed jrfastab closed 2 months ago

jrfastab commented 2 months ago

Newer kernels should not use probe_read so convert to probe_read_kernel. We have logic to revert to probe_read on older kernels. Further using probe_read instead of correct proberead{kernel|user} may fault on some architectures.

Changelog

Convert probe_read to probe_read_kernel.

Convert probe_read to probe_read_kernel to avoid possible runtime faults with probe_read on some architectures.
