This patch set is a collection of unrelated fixes for libbpf. Patch #1 fixes detection of corrupted BPF section w/ instructions. Patch #2 fixes possible errno clobbering. Patch #3 simplifies endianness check and brings it in line with few other similar checks in libbpf. Patch #4 adds check for failed map name retrieval from ELF symbol name. Patch #5 fixes return error code to be negative. Patch #6 fixes using valid fd (0) as a marker of missing associated BTF. Patch #7 removes redundant logic in two places. Patch #8 fixes typos in comments and debug output, and fixes formatting. Patch #9 unwraps a bunch of multi-line statements and comments. If patches #8 and #9 create too much history noise, I can drop them, they don't have functional changes.
