Bug description:
qemu-user passes through prctl(PR_SET_SECCOMP, SECCOMP_MODE_FILTER,
address) unmodified, but the third argument is an address to a BPF
filter, causing an EFAULT. Now, the filter is architecture-specifc, so
you can't just rewrite the addresses, so the safest bet is to just
return an error here.
I guess you should just return EINVAL, but not sure. I'd really like
something that can be identified, so seccomp errors can be ignored
when it's not supported.
