Daniel Borkmann 3aab8884c9 bpf, x64: fix memleak when not converging after image ... While reviewing x64 JIT code, I noticed that we leak the prior allocated JIT image in the case where proglen != oldproglen during the JIT passes. Prior to the commit e0ee9c1215 ("x86: bpf_jit: fix two bugs in eBPF JIT compiler") we would just break out of the loop, and using the image as the JITed prog since it could only shrink in size anyway. After e0ee9c1215, we would bail out to out_addrs label where we free addrs and jit_data but not the image coming from bpf_jit_binary_alloc().
