Would probably be good nevertheless to have this as a flag for
program loads, which gets then passed through to the verifier to
explicitly enable strict alignment checks.
Might certainly aide developing & testing programs on archs with
efficient unaligned access and later actually running them on archs
that don't have it. (And at minimum, it also helps for checking
the test suite against the verifier.)
Ok, I can implement this flag.
The only question is where to put it? An unused bit in the program
type? :-)
just add '__u32 prog_flags' to bpf_attr PROG_LOAD anon union.
There was no need for such flags in the past, hence no flags field
existed. Now it's time.
