Lu <[email protected]> Date: Wed Jul 1 10:15:30 2026 +0800 readelf: Update dynamic tag processing and validate section info Count DT_RELR relocations using dynamic tags when section header isn't used. Ignore section sh_offset and sh_size if they are larger than file size. One side effect is that we now display readelf: Warning: Ignore the out of range sh_offset value of 2199023261148 for section 17 readelf: Warning: Ignore the out of range sh_size value of 13 for section 17 with sh_offset value of 2199023261148 ...
