COREINJECT(1)

💖 COREINJECT(1) 💖

okay bestie, welcome to the coreinject page from the minicoredumper manual 💅 — yes the whole thing is in section 1, she's a user command, she's iconic, let's go 🫶

🌸 NAME 🌸

coreinject — inject binary dumps from minicoredumper(8) into a core file ✨

---

🎀 SYNOPSIS 🎀

coreinject [OPTION]... core symbol.map binary-dump...

---

🦋 DESCRIPTION 🦋

okay so picture this 😌 — an application is using libminicoredumper(7) and it registers a binary dump and is like "do NOT put this in the core file babes". so minicoredumper(8) is like say less, and makes a separate dump file holding the contents of that variable 💾. it also makes a symbol map file, symbol.map, because of course it does, she's thorough 👑

and that's where our girl coreinject comes in — using these files, coreinject can inject that binary data into the stripped core file so you can actually use it with gdb(1) 🙌 (no cap, this is the whole point).

now the options, bestie 👇

• --data=IDENT:SIZE@SRCFILE+SRCOFF — inject SIZE bytes of data from offset SRCOFF of file SRCFILE into the core(5). it drops that data at the location of the IDENT as stored in the symbol map. this one is lowkey the flex option: it's useful for injecting data other than the stuff that minicoredumper(8) actually dumped 👀✨

---

⭐ NOTES ⭐

listen, this part matters, don't skip it 🙈

• if the binary dump used MCD_DATA_PTR_DIRECT, then the separate binary file contains exactly that data. simple. clean. gorgeous 🌈
• if MCD_DATA_PTR_INDIRECT was used, then the separate binary file contains first the pointer value, followed by the data pointed to by the pointer. so like, pointer first, data second, that's the order, fr fr 💀

---

🔥 EXAMPLE 🔥

insert the binary data in bdump.bin into core 💫

coreinject core symbol.map bdump.bin
