"Cannot initialize system file configuration" #21

Closed magpie514 closed 2 years ago

magpie514 commented 2 years ago

System: Ubuntu 22.04 64b 123elf version: 199b81f400410d23b633ce00edd803bb4a327fd2 Terminal: Konsole (same issue with xterm)

I made a successful binary using the provided scripts and makefile, but executing it just returns a "123: Cannot initialize system file configuration" error. image Trying to run it with gdb doesn't return any form of crash or error message, it terminates normally.

Maybe I skipped some configuration step, but the binary seems fine.

taviso commented 2 years ago

Hmm interesting - thanks for the bug report.

I've never seen that error before, can you try updating to the latest commit to see if that fixes it? I made some filesystem related changes.

If it still shows that error, can you attach the strace output?

magpie514 commented 2 years ago

Thanks for replying! I tried updating, make clean and building again. Same error. Here is the strace output:

taviso commented 2 years ago

I think this must be because of the /proc/self/cwd usage. I've removed that now, so this might just start working. I have it working here in a virtual machine with 22.04, hopefully some of the recent cleanups fixed it!

magpie514 commented 2 years ago

So far it still does the same, even with the latest commits.

taviso commented 2 years ago

Is it possible you have an old ~/.l123set file? Could you try deleting it?

magpie514 commented 2 years ago

Tried deleting it, replacing it with a newer one, changing perms of that file, no change so far. Also tried using a different terminal (xterm, from Konsole) and also no difference. Currently at commit 33e945a5028e1044866979106541dc83a3393448, of course after make clean and rebuild. EDIT: Got no unusual partitions or complex mounts. Current uname -a output is Linux WINDINA 5.15.0-051500-generic #202110312130 SMP Sun Oct 31 21:33:20 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux.

magpie514 commented 2 years ago

This is interesting. I tried executing it using a temporary HOME. Like this, it runs. image image I don't think there's anything unusual about my HOME, it's a standard, unencrypted user folder in a /home mount point (ext4). What could be causing this?

taviso commented 2 years ago

Weird! I'm really confused, but I want to solve this -- everything in the strace looks totally normal.

If you don't mind trying a few things, maybe we can figure out what it's complaining about... If you run 123 under gdb, can you try breaking on lexit (that's not a typo, lexit not exit) and showing me the stack? Like this:

$ gdb ./123
(gdb) b lexit
Breakpoint 1 at 0x8117ec6
(gdb) r

That caught me off-guard. Not sure how to interpret this. Let me know if there's anything else I can try. Do you want the produced binary for a "biopsy", too?

taviso commented 2 years ago

Hmm, can you try exit with the l too? It usually calls lexit() when it can't start, so I assumed it would call that!

taviso commented 2 years ago

Hmm - I can see it reaches code that if it doesn't think your $HOME is valid (I know you had already figured that out, but just confirming from reading the code).

Things it rejects:

All of those seem fine to me:

statx(AT_FDCWD, "/home/magpie//", AT_STATX_SYNC_AS_STAT|AT_NO_AUTOMOUNT, STATX_BASIC_STATS, {stx_mask=STATX_BASIC_STATS|STATX_MNT_ID, stx_attributes=0, stx_mode=S_IFDIR|0755, stx_size=4096, ...}) = 0

The stat works, and says S_IFDIR...maybe I'm not translating it properly? 😕

Wait.. I think I have a theory, hold on for a patch!

taviso commented 2 years ago

I see this line in your strace output:

statx(1, "", AT_STATX_SYNC_AS_STAT|AT_NO_AUTOMOUNT|AT_EMPTY_PATH, STATX_BASIC_STATS, {stx_mask=STATX_BASIC_STATS|STATX_MNT_ID, stx_attributes=0, stx_mode=S_IFCHR|0600, stx_size=0, ...}) = 0

I don't think I translate S_IFCHR properly, but I don't know why it's doing that (edit: probably isatty()). Maybe just not returning an error on that case will fix it!

magpie514 commented 2 years ago

Pulled and rebuilt, but unfortunately no changes so far.

taviso commented 2 years ago

Hmm, okay.

So I think all of this is just it trying to clean up when it thinks it can't continue, the statx() is probably isatty(), and the ioctls() are trying to put the terminal back into a sane state.

statx(1, "", AT_STATX_SYNC_AS_STAT|AT_NO_AUTOMOUNT|AT_EMPTY_PATH, STATX_BASIC_STATS, {stx_mask=STATX_BASIC_STATS|STATX_MNT_ID, stx_attributes=0, stx_mode=S_IFCHR|0600, stx_size=0, ...}) = 0

exit_group(1)                           = ?

So the error must be just after this:

getcwd("/home/magpie/Repositories/123elf", 256) = 33

It only calls that from a few places, things it does:

taviso commented 2 years ago

Okay, last thing to try:

$ gdb ./123
(gdb) b *(path_exists+69)

(gdb) r

Do you also get 0x4000 if you try this?

As for the others:

taviso commented 2 years ago

Thanks, wow, it doesn't even reach there!

I am so confused!

taviso commented 2 years ago

There are only like two things that can fail before that.

I really can't see anything else that can fail.

That does cause the error you're seeing though:

Breakpoint 4, 0x0811d0b4 in unix_pathname ()
(gdb) return (int) 3
#0  0x0811d27b in path_exists ()
(gdb) c
Continuing.
123: Cannot initialize system file configuration

But "/home/magpie" is obviously a valid pathname --

Can you try this:

(gdb) b path_exists
Breakpoint 1 at 0x811d26f
(gdb) r
Breakpoint 1, 0x0811d26f in path_exists ()
(gdb) finish

Run till exit from #0  0x08110952 in config_init ()
0x0811214b in main_init ()
(gdb) p/x $eax
$2 = 0x0

I am determined to figure this out now 😆

magpie514 commented 2 years ago

Yeah, I got nothing either, this is quite strange. What makes things really confusing is it working in a different HOME. Tried a full reset of my local repository and extracting/building again, same results as well. 123.tar.gz This is my last produced binary, just in case you can spot something odd in it. EDIT: gdb session:

My keyboard is Spanish, but changing $HOME like I did should maintain the rest of the environment and DE settings. And yeah my home should be sane, or more than this would break, I think. No exotic setups there though, other than separating /home from / so it's on different disks, which is a fairly common setup.

taviso commented 2 years ago

Thanks for running all these tests! This part is interesting:

(gdb) p/x $eax
$1 = 0x3

It does think your pathname is invalid... but why? Your locale and everything else looks totally normal.

I'll have to think about this, it doesn't seem to use errno, but I pushed a change to set it just in case there is some redirection I don't understand. If that doesn't help, I'll have to sleep on it 😂

magpie514 commented 2 years ago

I'm sad to report it doesn't. I admit I'm also intrigued, I'll try a few things tomorrow, maybe changing some paths can make a difference.

taviso commented 2 years ago

Is it possible the fix for #45 might also fix this? 🤔

It is not allowed to use memcpy() with overlapping ranges, all kinds of random errors can occur, that was also true on UNIX. However.. it mostly seemed to kinda work on UNIX, and 123 does it all the time....which can make weird stuff happen on Linux, I decided to just replace every call to memmove() which is slower, but doesn't care if the ranges overlap.

If not I'm out of ideas without being able to single step through the code!

magpie514 commented 2 years ago

Pulled, cleaned, rebuilt binutils and rebuilt 123. Still no change. Tried building and running in different locations like /dev/shm or a first level subdir at $HOME and other partitions. Runtime path seems to be unrelated. It'd be really odd if it's the $HOME dir or its contents, because it doesn't seem to be trying to access other files or configs and it seems to find all files it needs before failing. The environment should still have contents of .profile or .bashrc if I just launch the program like HOME=/x/y/z 123.

Maybe Lotus really hated magpies and checks for the word in path...

So weird. What about if you do something like this:

$ env -i TERM=xterm HOME=~ ./123
magpie514 commented 2 years ago

image Hm, unfortunately no change.

taviso commented 2 years ago

I've read through every line of the code, it really seems okay!

I've been trying to do weird things to see how to reproduce it.

This works:

$ touch /tmp/foobar
$ chmod 0700 /tmp/foobar 
$ HOME=/tmp/foobar ./123 
123: Cannot initialize system file configuration

But obviously you would know if your $HOME was not a directory!

What does stat say, is your directory anything unusual, like a bind mount or something?

Maybe also the extended attributes, could this be a MAC issue, like selinux or something?

EDIT: huh that access time is in the future for some reason. I have noatime and nodiratime in my mount options, could that be?

taviso commented 2 years ago

Seems normal, although I guess it's weird that your atime is 20 years in the future... hmm, that is after 2038, the famous 2038 problem.

This is an interesting clue.

magpie514 commented 2 years ago

I actually just noticed that! Edited the post but you were faster :ninja: Yeah I have disabled access time in my mount options, maybe that's why it's off. Although it's the first time I find something that seems to care, how interesting. Maybe it's using some old-fashioned method and it's indeed running into that problem. Very interesting.

taviso commented 2 years ago

WOW

$ mkdir ~/tmp/bar
$ touch --date=2040-02-06 ~/tmp/bar/
$ HOME=~/tmp/bar ./123 
123: Cannot initialize system file configuration

This is the craziest bug I've seen for months lol.

Okay, now that I can reproduce I can track it down... hold on for a patch :)

magpie514 commented 2 years ago

touch ed my $HOME (without parameters for current date) and indeed, that makes it run normally! (of course I reset it so we can reproduce, but it's indeed the access date, that's amazing)

taviso commented 2 years ago

This is definitely the bug, if you use -D_FILE_OFFSET_BITS=64 (which I do) you get stat64, which is supposed to handle these issues. I can see the kernel reports the correct result, but glibc just returns EOVERFLOW.

Perhaps glibc also required __TIMESIZE == 64, but I tried that and no difference.

This is why your strace output looked fine, the kernel is working but glibc is returning the wrong result! Absolutely crazy combination of events.

I think you just haven't been seeing problems because it only affects 32bit processes. I think I need to check with a glibc internals expert to see if this is supposed to work.

magpie514 commented 2 years ago

This turned out to be really interesting after all! Thank you for your efforts and guesswork, this thread ended up with a plot twist! It was (the modern equivalent of) the Y2K bug all along! Technically my issue is solved, but I'll leave closing the issue to your discretion, if that's alright. In case there's more interesting information related to it. Again, thanks for your time!

Since I'm here, allow me to say this whole project is fascinating. Being able to work with such old, binary-only software and getting it to work (pretty well, all things considered!) is nothing but inspiring.

tavianator commented 2 years ago

Perhaps glibc also required __TIMESIZE == 64, but I tried that and no difference.

Does -D_TIME_BITS=64 help?

magpie514 commented 2 years ago

Can confirm that adding it to CPPFLAGS solves it. image

taviso commented 2 years ago

That was quite an adventure, wow!

Thanks @magpie514 for being willing to help track it down, and thanks @tavianator for figuring out the cpp incantation to solve it! Very relieved we figured out the mystery and things make sense again 😂

magpie514 commented 2 years ago

Glad to have been here. Thanks again for your time and ideas, this was indeed a good one!

adekorir commented 2 years ago

Fascinating.
