Add missing "prog '%s': " prefixes in few places and use consistently markers for beginning and end of program load logs. Here's an example of log output: libbpf: prog 'handler': BPF program load failed: Permission denied libbpf: -- BEGIN PROG LOAD LOG --- arg#0 reference type('UNKNOWN ') size cannot be determined: -22 ; out1 = in1; 0: (18) r1 = 0xffffc9000cdcc000 2: (61) r1 = *(u32 *)(r1 +0) ... 81: (63) *(u32 *)(r4 +0) = r5 R1_w=map_value(id=0,off=16,ks=4,vs=20,imm=0) R4=map_value(id=0,off=400,ks=4,vs=16,imm=0) invalid access to map value, value_size=16 off=400 size=4 R4 min value is outside of the allowed memory range processed 63 insns (limit 1000000) max_states_per_insn 0 total_states 0 peak_states 0 mark_read 0 -- END PROG LOAD LOG -- libbpf: failed to load program 'handler' libbpf: failed to load object 'test_skeleton' The entire verifier log, including BEGIN and END markers are now always youtput during a single print callback call. This should make it much easier to post-process or parse it, if necessary. It's not an explicit API guarantee, but it can be reasonably expected to stay like that. Also __bpf_object__open is renamed to bpf_object_open() as it's always an adventure to find the exact function that implements bpf_object's open phase, so drop the double underscored and use internal libbpf naming convention.
