Constant F_ANY_ALIGNMENT [src]

If BPF_F_ANY_ALIGNMENT is used in BPF_PROF_LOAD command, the verifier will allow any alignment whatsoever. On platforms with strict alignment requirements for loads and stores (such as sparc and mips) the verifier validates that all loads and stores provably follow this requirement. This flag turns that checking and enforcement off. It is mostly used for testing when we want to validate the context and memory access aspects of the verifier, but because of an unaligned access the alignment check would trigger before the one we are interested in.
