addrs2lines

addrs2lines is a utility command-line program in support of the memorizer project at Information Trust Institute at University of Illinois.

Usage

Assuming you have finished a memorizer run and have collected:

• vmlinux
• /proc/modules
• cp $(find /lib/modules/${uname -r} -name '*.ko' -print) .
• kmap, allocs, accesses, any or all of them.

Then a typical usage might look like this:

addrs2lines -e vmlinux -m modules -d . < kmap > kmap.out

Use of AI

Portions of this code were inspired by, adapted from, or copied from Github Copilot suggestions.

TODO

Faster. Maybe by making multiple copies of addr2line run in parallel.

Add tests. Currently kernel addresses are ad-hoc tested, but module addresses are untested.
