[SOLVED] Debugging enlightenment (with ASAN)

Message

lebarjack · Post by **lebarjack** » Fri Dec 02, 2022 5:15 pm

Hi everybody,

I encounter frequent crashes of enlightenment when interacting with discord (I suspect).
I would like to provide a useful stack trace or core dump and enlightenment has some safeguard which permit this [1].

I have read the gentoo wiki and applied what was suggested [2].
Enlightenment and efl are compiled with debugsyms and installsources but still, when a crash occurs, the enlightenment safeguard tells it is not able to launch gdb.

Anybody knows how to install efl & enlightenment with portage so that I obtain useful debugging information?

Do the instructions not work? Doesn't the the enlightenment-start process display the "Enlightenment Error" pop-up after a segfault? Does attaching GDB to the enlightenment process fail? How exactly?

The instructions seem to work if I send a SIGSEGV, but when the real crash occurs, I get the guru meditation which says that it couldn't run gdb to get a backtrace.

.e-crashdump.txt read:

Code: Select all

The program is not being run.

I was to quick to cancel the dialog, but I will try to attach to the process with

Code: Select all

gdb enlightenment $(pidof enlightenment)

the next time enlightenment crash.

You could attach gdb prior to the crash, and it will automatically trap when the signal occurs.

It seems I cannot attach gdb to the process. It's already monitored by enlightenment_start

I tried to get rid of the "ptrace: Operation not permitted." but I have no hardened kernel, nor have I any yama directory in my /proc

Hi,

I got the crash to reproduce and got some information in enlightenment's crashdump file.
Yet, the guru meditation dialog announce that it couldn't launch a gdb session.

At this point, I think I will contact upstream.

If someone is interested, I published some information here:
https://pastebin.com/13XUNNru

Thanks a lot for your time and your help.

I find it weird and a bit concerning that upstream rigged their own ptrace monitor to manage this constantly. That seems like a lot of effort for a stable program that should not need monitoring, which suggests they think it is not stable.

The backtrace would be more useful if libc had symbols, but I think this is the guilty part:

If I had to guess, the heap is corrupted, the call to malloc detected that corruption, and led to a call to abort. If so, running under a heap debugger might yield more information. Valgrind is very good at that, but also quite slow.

I was told to build efl and enlightenment with ASan to produce a better crash dump.
I naively thought I would just add some -fsanitize to my CFLAGS, but this does not work...
Meson quickly spits some error

Here is my efl env file

Code: Select all

$ cat /etc/portage/env/dev-libs/efl
CFLAGS="${CFLAGS} -fsanitize=address"
CXXFLAGS="${CXXFLAGS} -fsanitize=address"
LDFLAGS="${LDFLAGS} -fsanitize=address"

in short, it stops here

I seems I have problem emerging any package with ASAN as long as it uses meson building tools.
I will open a new thread concerning this subject on portage & programming.

Post by **sam_** » Fri Jan 27, 2023 9:19 am

Try FEATURES="-sandbox -usersandbox" emerge -v1 ...

This is required because both ASAN and sandbox use LD_PRELOAD. I'll document this on the wiki later.

Enabling ASan is done by passing the -Db_sanitize=address option to the meson build system,

I found this while googling the problem.
I will try that later.

Post by **sam_** » Fri Feb 03, 2023 11:24 am

Could you maybe share the meson log in full? Also, is USE=sanitize enabled on gcc?

lebarjack · Post by **lebarjack** » Fri Feb 03, 2023 11:57 am

Yes, gcc is installed with the use sanitize

Thanks! Could you try the settings at https://wiki.gentoo.org/wiki/AddressSanitizer#Per-package?

Note that you may need to comment out the *FLAGS bits and only set MYMESONARGS for a Meson package (because it'll handle putting the flags in the right place for you).
