Something wrong with i686 (magic numbers) #8

tieugene · 2021-01-21T15:56:31Z

Due this log make check on x86 ends with:

This is exactly i686 error. Other builds OK.

Thanks for catching it. The first thing I want to distinguish is whether the error happens always or not. I mean, I want to distinguish whether it is a threading problem (race condition) or not. Do you reproduce the same error if you run the check command again?

The say - not always.

I mean, I want to distinguish whether it is a threading problem (race condition) or not. Do you reproduce the same error if you run the check command again?

As for me I'm at x64 host (Fedora 33) and have no i686 near (Fedora not distributed in i686 version starting from F32).
But koji system bulds i686 yet. Somewhere in clouds.
Seems anybody with i686 linux host wanted.

Hi, I am the reviewer in the linked Fedora bug. To clarify, this error occurs every time. I can easily reproduce it outside the Fedora build system, and even without any patches or extra build flags from the distribution. All it takes, on my x86_64 system, is ./configure && make && make check in a 32-bit (i386/i686) chroot.

The tests do occasionally die with “Aborted (core dumped)” in check-treedbm-perf on some platforms, but this is a different problem, and I do not know if it reflects a bug in tkrzw or a problem in the environment. That may be what caused the confusion.

estraier · 2021-01-22T14:49:08Z

Hi Ben, Thanks for the explanation. I don't have an i686 environment either. By design, Trkzw doesn't depend on specific CPU design, bus width, or endian. So, it's strange to me that the test fails on i686 only. Do you know other environments where the test fails?

May be the problem is not in exactly i686 but in 32-bit.
Fedora's koji system builds for: s390x (IBM System Z), PPC64 (PowerPC), AARCH64 (ARM64), x86_64, i686, ARMv7.
But only i686 is 32-bit (don't know about ARMv7) and produces test error.

What about byte align?

musicinmybrain · 2021-01-22T15:19:29Z

ARMv7 is 32-bit, so it is not just that. And ARM is stricter about alignment than x86, and has a weaker memory model.

Passing --enable-debug or --disable-opt to configure makes no difference, by the way.

I’m happy to try any tests that are helpful.

estraier · 2021-01-22T15:39:30Z

I'd like to know this test fails or not. The difference is the number of threads is 1.

./tkrzw_dbm_perf sequence --dbm skip --file mmap-para --path casket.tks --iter 20000 --threads 1 --size 8 --step_unit 4 --max_level 10

If it doesn't fail, please increase the iteration (the value of --iter) to 100000.
The point is, I'd like to locate the reproducible point where the segmentation fault (or bus error or anything critical) happens.
If it tails, I'd like to see the stack trace.

BTW, running the same test with "valgrind" doesn't report any abnormality on my x86_64 environment.
It means that memory violation doesn't happen in the test, on my environment.
Is it possible to run the test with valgrind on i686?

The same test does not fail under valgrind:

Nor does it fail under valgrind with --iter 100000, or --threads 5.

estraier · 2021-01-22T17:46:38Z

Thanks. If the test with --threads 1 fails, the problem is not related to threading. There should be some deterministic wrong behavior in Tkrzw's implementation. But, one weird thing is that running on valgrind avoids the failure. Anyway, I'll go over the code to locate the cause.

I'm now trying to verify this issue on VMware.
Where's the ISO image of the exact version on which you found the bug?

musicinmybrain · 2021-04-28T19:05:16Z

Fedora Linux builds some “multilib” i686 packages as part of the x86_64 architecture, but doesn’t build a complete 32-bit release anymore.

I expect you can best reproduce this by using the x86_64 DVD ISO for the just-released Fedora 34 from here, and adding -m32 to the compiler and linker flags. I’ll try it out myself and report back.

musicinmybrain · 2021-04-28T20:03:04Z

OK, so I started the live DVD I linked, started “Terminal” (gnome-terminal), and ran:

sudo dnf install gcc-c++ libstdc++-devel.x86_64 libstdc++-devel.i686 libgcc.i686 glibc-devel.i686

wget https://github.com/estraier/tkrzw/archive/0d7badb65abcac72381ecc6fbd8f980ce6a53305.zip
unzip 0d7badb65abcac72381ecc6fbd8f980ce6a53305.zip
cd tkrzw-0d7badb65abcac72381ecc6fbd8f980ce6a53305/

CXXFLAGS=-m32 LDFLAGS=-m32 ./configure
# Change the number of parallel jobs as desired; my VM had 4 CPUs and adequate memory
make -j4
make check

After a while (my workstation is an antique) I get:

make check-skipdbm-perf

Manually running the test we were looking at previously,

LD_LIBRARY_PATH=$PWD ./tkrzw_dbm_perf sequence --dbm skip --file mmap-para --path casket.tks --iter 20000 --threads 1 --size 8 --step_unit 4 --max_level 10

fails too.

So it seems that’s a good way to reproduce it.

Thanks. Reproduction is the greatest step to fix an issue! BTW, the ISO image you wrote is for 64 bit. Is it intended?

This issue could be reproducible on Ubuntu 20.01 x64 if -m32 is attached to the build command.
And, I found the bug.
A pointer variable could overflow on 32-bit systems.
I committed the CL to fix it.

Thanks so much.
I appreciate people who test the product on various environments/settings.
