Commit Message

api: fix seccomp_export_bpf_mem out-of-bounds read

*len is the length of the destination buffer, but program->blks is
probably not anywhere near that long.  It's already been checked above
that BPF_PGM_SIZE(program) is less than or equal to *len, so that's
the correct value to use here to avoid either reading or writing too
much.

I noticed this because tests/11-basic-basic_errors started failing on
musl after e797591 ("all: add seccomp_precompute() functionality").
