RecursionError when connecting to qemu target

[justfoxing]

Description

• pwndbg after commit dc0e1f4 (including current latest 2bef07f) continuously throws RecursionErrors when connecting to a qemu target (qemu-arm and qemu-x86_64 both show the same behaviour) and doesn't display the pwndbg UI.
• Before commit dc0e1f4, no errors occur. This commit is "elf.py: optimize get_ehdr" and adds the pwndbg.vmmap.find() call into get_ehdr(), which is where the recursion seems to come into play, so I'm pretty sure it's the problem.
• Using a non-qemu target (including a native one running under gdbserver), no errors occur.

Steps to reproduce

qemu-x86_64 -g 1234 `which ps`
gdb `which ps` # note: need to provide the target binary on the command line or the issue won't trigger.
pwndbg> target remote :1234

Output is then:

(If you want the full traceback for some reason, let me know, but it's just recursing through the same functions until it falls over).

Hey, thanks for reporting this. I'll try to investigate this issue

[disconnect3d]

note: need to provide the target binary on the command line or the issue won't trigger.

Interesting, it seems this could be some caching issue, but when we disable memoization/caching with memoize command (or by changing pwndbg/memoize.py caching=False) this still triggers.

[disconnect3d]

This can maybe be diagnosed/compared by using set debug-events on in config.

[disconnect3d]

The issue is that I introduced a cyclic dependency between pwndbg.vmmap.find and get_ehdr functions in some cases: when vmmap.find can't use proc_pid_maps (e.g. on qemu-user) it tries to fetch things via AUXV: if it doesn't find it, it will use pwndbg.vmmap.info_files function which parses the info files command from GDB and may then execute pwndbg.elf.map function which then uses get_ehdr which uses vmmap.find and we get the recursion.

Now:

• if we launch gdb <file> -ex 'target remote :1234' - info files will return data which will be processed and pwndbg.elf.map is executed - causing recursion error
• if we launch gdb -ex 'target remote :1234 - pwndbg does not crash, but our vmmap information is still bad (we only get them through register exploration :/)

FWIW gef also did not figure this out: they only have a single vmmap page: 0-xffff.... on qemu-user targets.

[disconnect3d]

@justfoxing this should be fixed with the recent commit.

Although its not ideal: I made it so we just return a Page(0, 0xfffffffff...) which is not quite correct.

[justfoxing]

Cheers, confirmed working for me, thanks for the quick fix.

@stong eh, can you see if this fixed your issue? e239e9c

Is this a qemu user mode or qemu kernel?

Can you provide a testcase so I can improve this?

[stong]

Actually this binary is not qemu whatsoever. It is just a normal ELF compiled by clang.

By the way, I forgot to say this but thank you @justfoxing for the accurate issue description with the offending commit hashes. I was able to workaround by checking out commits prior to that

[disconnect3d]

Is this on ARM64 linux then? Or is it a binfmt misc that actually runs qemu user mode under th hood?

[stong]

Yes, it's running on a Raspberry Pi.

Something else I might add --- commands like bins and tcache don't seem to work as these values got optimized out and pwndbg can't find them by symbol -- unfortunate :( But that is a separate issue.

[disconnect3d]

Can you show output of this command?: gdb --quiet /bin/ls -ex 'set context-sections ""' -ex entry -ex 'info proc mapping' -ex vmmap

[stong]

Ah, interesting it seems to be an issue specific to core files.

[disconnect3d]

Wait, why doesn't it trigger now?

EDIT: Btw it may be better to communicate via Discord: we have a Pwndbg server at https://discord.gg/pNhrz52s

[stong]

OK, will do. It seems to happen when I do gdb a.out core but indeed doesn't happen with the above command line

[Sparrrgh]

I'm getting this same error, in the same parts of the code, but on an amd64 binary. It happens inside of a recursive function, after the first level of recursion

Just to make sure it's exactly the same issue

[disconnect3d]

@Sparrrgh can u show how we can reproduce this? e.g. exact binary/setup?

[cnwangjihe]

have the same issue when loading coredump.
using gdb ./test ./core
test.tar.gz

[disconnect3d]

@cnwangjihe are u using latest pwndbg? and which version of gdb? for @Sparrrgh it seemed that a gdb or pwndbg update helped..

Can u show output of the version command?

[cnwangjihe]

Hey,

There are three separate issues here:

1. Us not handling some cases gracefully, and so crashing on them
2. Getting memory maps info when debugging core dumps
3. Getting memory maps info when debugging a QEMU user emulated process

The first case has hopefully been resolved with #1079 and a recent commit.

The 2nd case has been mainly resolved in #1079. However, this is not perfect: it does not give 100% accurate vmmap info because the data we fetch vmmap information from, namely: info proc mappings and maintenance info sections commands, may not give us ALL information.

For what is worth, the GDB's generate-core-file command has also this problem where it does not provide all possible info into the generated corefile. I have filled a GDB bugzilla issue about it here: https://sourceware.org/bugzilla/show_bug.cgi?id=29508

For the 3rd case, the problem is related to the QEMU user emulation's gdbstub being underdeveloped. It lacks a few features related to getting files from the debugged target. I have been working some time ago on a patch to fix that in QEMU, which you can find here: https://lore.kernel.org/all/20220221030910.3203063-1-dominik.b.czarnota@gmail.com/ and while it works, it need a few improvements and tests. I hope to find some time in the soonish future to work on that and finish that.

In theory, for 3rd we could parse the QEMU's process memory maps and filter them by ourselves. However, this would only work if the QEMU process is run locally and would not work if it hosts its gdbstub from a remote server.

Anyway, I am closing this issue for now, as the main problem, which is recursion error - should now be fixed.

@kevinpark1217 hey, can you try updating ur pwndbg version? The f2fcc95 version is from may and we have had some fixes to this problem recently. Please, let me know if the latest dev branch or current release (those are the same version fwiw) work for you.

That's interesting, thanks, we will have to fix this:

@Erebua just to be sure, you installed pwndbg inside the qemu system image, right?

If you have direct steps how to reproduce ur case I'd appreciate that

[disconnect3d]

@Erebua #1107 may have fixed your cause, but I still haven't been able to reproduce it so I can't really check

[Erebua]

I installed pwndbg in attifyos
I also installed qemu-system in this system.

qemu-system

chroot . ./gdbserver 192.168.134.143:6666 ./pwnable/Intro/stack_bof_01 "aaaa"

attifyos

gdb-multiarch
set arch mips
target remote 192.168.134.143:6666

but what is the 'explored' mean?
Is there some way to get the libc path?

[disconnect3d]

Wait, how exactly are u running all this? How do u run the qemu-system? Can u give commands for that?

The vmmap u showed is a bit weird: that's what you usually may get if we can't get memory maps information, e.g. when debugging a core dump.

but what is the 'explored' mean?

The <explored> part is memory map created by exploring the addresses your registers were pointing at and which were not mapped in any other existing memory map. To be honest that's still not ideal and I thought to remove this functionality at one point but it seems it is helpful here, heh.

Is there some way to get the libc path?

Usually, the GDB's info sharedlibrary should show you something like this:

pwndbg> info sharedlibrary
From                To                  Syms Read   Shared Object Library
0x00007ffff7dd3f10  0x00007ffff7df4550  Yes         /lib64/ld-linux-x86-64.so.2
0x00007ffff7bb1210  0x00007ffff7bc84cf  Yes (*)     /lib/x86_64-linux-gnu/libselinux.so.1
0x00007ffff77db360  0x00007ffff7953afc  Yes         /lib/x86_64-linux-gnu/libc.so.6
0x00007ffff754a570  0x00007ffff759b35d  Yes (*)     /lib/x86_64-linux-gnu/libpcre.so.3
0x00007ffff7345e50  0x00007ffff7346bee  Yes         /lib/x86_64-linux-gnu/libdl.so.2
0x00007ffff712bbb0  0x00007ffff713a1f1  Yes         /lib/x86_64-linux-gnu/libpthread.so.0
(*): Shared library is missing debugging information.

But given your vmmap output the info sharedlibrary command from GDB will likely not work? :(

[disconnect3d]

@Erebua since this is not anymore about a recursion error, can you provide all necessary information to reproduce your issue in a new one and I will close this one?
