{"enrichment":{"faq":[{"a":"elf-inspection helps you examine dynamic linking dependencies using standard tools. Run `ldd <binary>` to list all required shared libraries and their paths. For more detail, use `readelf -d <binary>` to inspect the DYNAMIC section, or `objdump -p <binary>` to see program headers. elf-inspection guides you through interpreting these outputs to diagnose missing libraries and linking issues.","q":"How to check what libraries a binary depends on?"},{"a":"elf-inspection teaches you to diagnose undefined symbol and linker errors by inspecting symbol tables. Use `nm <binary>` to list symbols and identify undefined ones (marked 'U'). Check `readelf -s <binary>` for detailed symbol info including binding and visibility. elf-inspection helps you trace whether symbols are missing from dependencies, incorrectly stripped, or have visibility issues.","q":"What causes undefined reference errors in Linux binaries?"},{"a":"elf-inspection provides workflows to analyze binary size and identify bloat contributors. Use `size <binary>` for a quick overview of text, data, and bss sections. Run `readelf -S <binary>` to see all section sizes, or `objdump -h <binary>` for headers. elf-inspection helps you spot oversized debug sections, unused code, or bloated dependencies driving binary growth.","q":"How big is my ELF binary and why?"},{"a":"elf-inspection guides you to extract debug info and build metadata from executables. Use `readelf -S <binary>` and look for .debug_* sections like .debug_info and .debug_line. Run `file <binary>` to see if it's stripped. Use `objdump -g <binary>` or `readelf --debug-dump=info <binary>` to inspect DWARF debug data. elf-inspection helps you verify symbol availability for debugging.","q":"How do you check if a binary has debug symbols?"},{"a":"elf-inspection teaches you to inspect symbol tables in shared libraries using `nm -D <library>` to list dynamic symbols, or `readelf -s <library>` for full symbol details. Filter by GLOBAL and FUNC to find exported functions. Use `objdump -T <library>` for dynamic symbol table. elf-inspection helps you verify that required symbols are present and correctly bound.","q":"What symbols does a shared library export and how?"},{"a":"elf-inspection guides you to verify security properties and hardening flags. Use `readelf -l <binary>` to check for RELRO segments and stack canary indicators. Run `file <binary>` to see if it's position-independent (PIE). Use `checksec` or parse ELF headers with `readelf -e <binary>` to confirm NX, ASLR, and stack protection. elf-inspection helps you assess security posture.","q":"How do you check binary hardening flags like PIE and RELRO?"}],"shadow_tags":["binary-analysis","linux-tooling","symbol-resolution","dynamic-linking","security-hardening","performance-profiling","debugging-aids","executable-format"],"summary_rewrite":"Master Linux binary analysis with workflows for examining symbol tables, section layout, dynamic linking, and debug information.
