selftests/bpf: Add tests for reference tracking
reference tracking: leak potential reference reference tracking: leak potential reference on stack reference tracking: leak potential reference on stack 2 reference tracking: zero potential reference reference tracking: copy and zero potential references reference tracking: release reference without check reference tracking: release reference reference tracking: release reference twice reference tracking: release reference twice inside branch reference tracking: alloc, check, free in one subbranch reference tracking: alloc, check, free in both subbranches reference tracking in call: free reference in subprog reference tracking in call: free reference in subprog and outside reference tracking in call: alloc & leak reference in subprog reference tracking in call: alloc in subprog, release outside reference tracking in call: sk_ptr leak into caller stack reference tracking in call: sk_ptr spill into caller stack reference tracking: allow LD_ABS reference tracking: forbid LD_ABS while holding reference reference tracking: allow LD_IND reference tracking: forbid LD_IND while holding reference reference tracking: check reference or tail call reference tracking: release reference then tail call reference tracking: leak possible reference over tail call reference tracking: leak checked reference over tail call reference tracking: mangle and release sock_or_null reference tracking: mangle and release sock reference tracking: access member reference tracking: write to member reference tracking: invalid 64-bit access of member reference tracking: access after release reference tracking: direct access for lookup unpriv: spill/fill of different pointers stx - ctx and sock unpriv: spill/fill of different pointers stx - leak sock unpriv: spill/fill of different pointers stx - sock and ctx (read) unpriv: spill/fill of different pointers stx - sock and ctx (write) Signed-off-by:Joe Stringer <joe@wand.net.nz> Signed-off-by:
