ENUM DSO_BINARY_TYPE(9)

✨ enum dso_binary_type(9) ✨

okay so this is a page from the Kernel API Manual, and it's all about the enum dso_binary_type — like, the glow-up list that tells you what kind of DSO a memory region is rocking. and yes bestie, "memory region" here means a struct map, iykyk 💅

🦋 NAME 🦋

enum dso_binary_type — the kind of DSO generally associated with a memory region (that's a struct map, btw 🫶).

🎀 Constants 🎀

like, every single member of the squad, one by one, no skips 💖

• DSO_BINARY_TYPE__KALLSYMS — symbols from the /proc/kallsyms file ✨

• DSO_BINARY_TYPE__GUEST_VMLINUX — path to the guest kernel /boot/vmlinux file 🦋
• DSO_BINARY_TYPE__JAVA_JIT — symbols from the /tmp/perf.map file ⭐
• DSO_BINARY_TYPE__DEBUGLINK — a debug file you can read straight from the file path in the .gnu_debuglink ELF section of the dso 🔥
• DSO_BINARY_TYPE__BUILD_ID_CACHE — a file named after the buildid, chilling in the buildid cache with an elf filename 💅
• DSO_BINARY_TYPE__BUILD_ID_CACHE_DEBUGINFO — a file named after the buildid, chilling in the buildid cache with a debug filename 🌸
• DSO_BINARY_TYPE__FEDORA_DEBUGINFO — debug file in /usr/lib/debug with a .debug suffix 🍓
• DSO_BINARY_TYPE__UBUNTU_DEBUGINFO — debug file in /usr/lib/debug 💜
• DSO_BINARY_TYPE__MIXEDUP_UBUNTU_DEBUGINFO — the dso__long_name debuginfo file living in /usr/lib/debug/lib instead of the expected /usr/lib/debug/usr/lib 🙈 (yes, "mixedup" is literally the name, it's giving chaotic energy)
• DSO_BINARY_TYPE__BUILDID_DEBUGINFO — a file named after the buildid, located in /usr/lib/debug/.build-id/ 🌈
• DSO_BINARY_TYPE__GNU_DEBUGDATA — MiniDebuginfo, where a compressed ELF file gets placed in a .gnu_debugdata section 🎀

• DSO_BINARY_TYPE__GUEST_KMODULE — guest kernel module .ko file 🧚
• DSO_BINARY_TYPE__GUEST_KMODULE_COMP — guest kernel module .ko.gz file 😭 (compressed era)
• DSO_BINARY_TYPE__SYSTEM_PATH_KMODULE — kernel module .ko file 👑
• DSO_BINARY_TYPE__SYSTEM_PATH_KMODULE_COMP — kernel module .ko.gz file 🔥
• DSO_BINARY_TYPE__KCORE — the /proc/kcore file 💀
• DSO_BINARY_TYPE__GUEST_KCORE — the guest /proc/kcore file 🦋

• DSO_BINARY_TYPE__BPF_IMAGE — jitted BPF trampoline or dispatcher code ✨
• DSO_BINARY_TYPE__OOL — out of line code, like kprobe-replaced instructions, or optimized kprobes, or ftrace trampolines 🔥
• DSO_BINARY_TYPE__NOT_FOUND — unknown DSO kind, the "idk her" of the enum 😭
