[Xenomai] beaglebone: arm: xeno-test gives segmentation fault - test dlopen failed

[Xenomai] beaglebone: arm: xeno-test gives segmentation fault - test dlopen failed

[Pintu Kumar]

Hi,
I am using Kernel 4.9.51 for beagle bone black with xenomai patches
from xenomai-next repo.

I have installed xenomai-3-next using below:
# ./scripts/bootstrap
# ./configure --with-pic --with-core=cobalt --enable-smp --disable-tls
--enable-dlopen-libs
# make
# make install

After that when I run xeno-test I get below error, and the test stopped.

# root@bdk:~# /usr/xenomai/bin/xeno-test
....
....
vdso_access OK
xddp skipped (no kernel support)
Segmentation fault
/usr/xenomai/bin/smokey: test dlopen failed: Unknown error -1

If you have any clue about this error, please let me know.


Thanks,
Pintu

Re: [Xenomai] beaglebone: arm: xeno-test gives segmentation fault - test dlopen failed

[Pintu Kumar]

Dear Greg,

Please let me know how to disable "dlopen" test in xenomai-next.

I even tried, without dlopen parameter during ./configure but still I
get the same issue.
#  ./configure --enable-smp

We did not face this issue earlier on xenomai-3 stable branch.
So, I am planning to disable it right now.
Please help!


Thanks,
Pintu

[Greg Gallagher]

Hi,
  I'll take a look at this tonight.  I'll confirm if this test  is
crashing on all platforms or just BB.  To disable I believe you'll
have to recompile the tests.

Re: [Xenomai] beaglebone: arm: xeno-test gives segmentation fault - test dlopen failed

[Pintu Kumar]

Ok Greg thanks a lot.

Yes, I can recompile it, but for now I want to get rid of this dlopen
to pass rest of xeno-test.
Please let me know how to disable it from configure.ac

Thanks,
Pintu

Re: [Xenomai] beaglebone: arm: xeno-test gives segmentation fault - test dlopen failed

[Pintu Kumar]

One more thing,
On x86 xeno-test works fine even with dlopen.

This problem is seen only of arm and arm64 boards.

Re: [Xenomai] beaglebone: arm: xeno-test gives segmentation fault - test dlopen failed

[Pintu Kumar]

Dear Henning,

I saw your commit regarding dlopen here:
https://xenomai.org/pipermail/xenomai/2018-February/038351.html

We are facing dlopen error with xeno-test on arm (beagle bone) and
arm64 (hikey) boards.
Segmentation fault
/usr/xenomai/bin/smokey: test dlopen failed: Unknown error -1

Do you have any clue regarding this issue.
Earlier xeno-test worked for us, but after this commit xeno-test is failing.

Currently we dont need dlopen test.
So, please let us know how to disable dlopen test to pass the xeno-test report.


Thanks,
Pintu

Re: [Xenomai] beaglebone: arm: xeno-test gives segmentation fault - test dlopen failed

[Henning Schild]

Hi Pintu,

i guess you might be using v3.0.6. There are a couple of commits on top
of that
https://gitlab.denx.de/Xenomai/xenomai/commit/aa008686091484c88cbb809bc190133a98769a30
and 2 parents
All three are in v3.0.7, which hopefully solves your problem.

regards,
Henning

Re: [Xenomai] beaglebone: arm: xeno-test gives segmentation fault - test dlopen failed

[Pintu Kumar]

Hi,

One doubt, how do we clone 3.0.7 ?
Is it part of the following branches?
  remotes/origin/next
  remotes/origin/stable/v3.0.x

I could not find any branch with the name 3.0.7.

Is all 3 patches important, or only this is fine:
build: link dlopen libs with "nodelete"
smokey/dlopen: fix testcase

Sorry, but can you list down all 3 commits.


Thanks,
Pintu



Thanks,
Pintu

Re: [Xenomai] beaglebone: arm: xeno-test gives segmentation fault - test dlopen failed

[Pintu Kumar]

Hi,

Sorry, but both the below patches are already applied to my xenomai-next repo:
build: link dlopen libs with "nodelete"
smokey/dlopen: fix testcase

Still I am facing dlopen issue.
Is there any other patches I am missing?


Thanks,
Pintu

Re: [Xenomai] beaglebone: arm: xeno-test gives segmentation fault - test dlopen failed

[Greg Gallagher]

I'm not that familiar with autotools (still learning), but I removed
this from configure.ac :

diff --git a/configure.ac b/configure.ac
index 4f9b1f9..a84dd14 100644
--- a/configure.ac
+++ b/configure.ac
@@ -881,7 +881,6 @@ AC_CONFIG_FILES([ \
        testsuite/spitest/Makefile \
        testsuite/smokey/Makefile \
        testsuite/smokey/arith/Makefile \

        testsuite/smokey/sched-quota/Makefile \
        testsuite/smokey/sched-tp/Makefile \
        testsuite/smokey/setsched/Makefile \

And I don't see the dlopen tests being built.  This may get you past
the test failing for now.  I'll add to the to do llist to test this
with the latest version of the stable branch.

Re: [Xenomai] beaglebone: arm: xeno-test gives segmentation fault - test dlopen failed

[Henning Schild]

Hi,

could you please try v3.0.7 (733a32b71f77dfb3e7a64039d0692e6c9d5d1cfe)
this is a tag not a branch. Or use branch "stable/v3.0.x".
The commit from "next" you mentioned does not exist anymore, one of the
pleasures of using git ... do not use "next" unless you really have to!

If you are not using dlopen just drop "--enable-dlopen-libs" from your
configure options.

Henning

How to clone 3.0.7 as a git repo (not the tar)?

Ok, will try with stable on Beaglebone. But as I see stable also
contains the same dlopen fixes.

I guess, arm64 support is present only on "next" branch.
Since we want to maintain single kernel for all (x86, arm, arm64) we
choose next branch.
And AFAIK, next branch should always contain all the patches from
previous stable branch.

Yes, I did not use this, but still I get dlopen error on ARM - beaglebone.
I just used:
# ./configure --enable-smp

Also, on x86, it works if I just use:
# ./configure

But same dlopen error if I use:
# ./configure --enable-dlopen-libs

And, I wanted to know how to disable this config from xenomai-3 - configure.ac
CONFIG_XENO_LIBS_DLOPEN

Re: [Xenomai] beaglebone: arm: xeno-test gives segmentation fault - test dlopen failed

[Henning Schild]

Hi,

i had a closer look. You might want to revert the following commit
https://gitlab.denx.de/Xenomai/xenomai/commit/408c93e26438c83c08f216a2c8bd7079253cf71a

It does include the testcase in the build even if the feature is
disabled.

I don't think so. It includes the testcase in the source distribution
allowing "make distcheck" to succeed, even if the test has not be built
in the smokey driver, which fixes a build regression introduced by
dlopen. Tests built in the executable must be listed in COBALT_SUBDIRS,
which dlopen isn't unless --enable-dlopen-libs has been given.

If you want to exclude the dlopen test from the test series at runtime,
you can pass "--exclude=dlopen" on the command line to smokey, as
mentioned in the help strings (smokey --help).

Yes, you are right. I just saw a "+= dlopen" in the resulting Makefile
but that should not cause the problem.

Pintu: Please build in a completely fresh environment i.e. "git clean
-dfx; autoreconf -i; ./configure". And now give me

grep dlopening -A1 config.log
grep am__append_1 testsuite/smokey/Makefile
autoreconf --version

Ideally with a hash i can find on gitlab.denx.de.

OK. Thank you so much.
I will try this on Monday and let you know.

OK. Thanks for this info. However, when I run xeno-test it
automatically includes smokey test.
How do I exclude from xeno-test itself ?
We have a criteria to attach xeno-test report as the success result.

Re: beaglebone: arm: xeno-test gives segmentation fault - test dlopen failed

[Pintu Agarwal]

Dear Henning, Greg and all,

Sorry, re-checking after a long time.

The dlopen test is still failing on Beagle Bone black with xenomai-3.
Yesterday, I just freshly cloned the xenomai-3 repo, build and install
on beagle bone black, then run xeno-test/smokey test.
Found that dlopen test is still crashing. I though this issue is
already fixed, but not.

Here are the results:

~/xenomai-3# cat .git/config
url = https://git.xenomai.org/xenomai-3.git

~/xenomai-3# git branch
* master

./configure --with-pic --with-core=cobalt --enable-smp --disable-tls
--enable-dlopen-libs
make
make install

:/usr/xenomai/bin# ./smokey --run
arith OK
bufp skipped (no kernel support)
cpu_affinity OK
fpu_stress OK
iddp skipped (no kernel support)
leaks OK
memory_coreheap OK
memory_heapmem OK
memory_tlsf OK
net_packet_dgram skipped (no kernel support)
net_packet_raw skipped (no kernel support)
net_udp skipped (no kernel support)
posix_clock OK
posix_cond OK
posix_fork OK
posix_mutex OK
posix_select OK
rtdm skipped (no kernel support)
sched_quota skipped (no kernel support)
sched_tp skipped (no kernel support)
setsched OK
sigdebug skipped (no kernel support)
timerfd OK
tsc OK
vdso_access OK
xddp skipped (no kernel support)
Segmentation fault
./smokey: test dlopen failed: Unknown error -1

~/xenomai-3# /usr/xenomai/bin/dlopentest
Segmentation fault

So, basically, dlopentest results into Segmentation Fault on arm.

Note:
Disabling dlopen from "configure" does not cause this issue, and
xeno-test/smokey test pass successfully.
But I am wondering why dlopen test may fail on arm (on x86 it works).

So, it some packages or configuration that I am missing on my Beagle Bone ?
Can anybody describe the root cause (if already investigated earlier)...

Thanks,
Pintu

Hi,

I am investigating this issue.
Currently I found that normal "dlopen" tests is working fine on Beagle Bone.
There is some crash happening in: my_dlopen()

Hopefully, I might be able to fix this issue and release a patch, in 2
weeks times.

Thanks,
Pintu

Re: beaglebone: arm: xeno-test gives segmentation fault - test dlopen failed

[Pintu Agarwal]

Hi,

What is the problem with "rt_queue_create" in the below code:

static size_t def_mem_pool_size = 1024 * 1024;
int libalchemy_func(void)
{
        RT_QUEUE queue;
        int ret=0;

        printf("%s called..\n", __func__);

 //       ret = rt_queue_create(&queue, "q0", def_mem_pool_size,
 //                     Q_UNLIMITED, Q_FIFO);
        if (ret) {
                printf("rt_queue_create - failed...\n");
                return ret;
        }
//      ret = rt_queue_delete(&queue);

        return ret;
}

xenomai-3/testsuite/smokey/dlopen# ./dlopentest
Segmentation fault

The dlopentest gives Segmentation Fault only if rt_queue_create is
invoked, else it works.
However, libposix-test.so works without any issue.

Any clue on this?

Thanks,
Pintu

Re: beaglebone: arm: xeno-test gives segmentation fault - test dlopen failed

[Pintu Agarwal]

Dear Greg,

If you have any comments about dlopentest failure (both x86/arm)
please let me know.

Currently, we found that if we include "localmem=tlsf" option in
configure, the dlopen test is passing.
./configure --with-pic --with-core=cobalt --enable-smp
--enable-dlopen-libs --with-localmem=tlsf
make
make install
#testsuite/smokey/dlopen# ./dlopentest
done....

For this I have few questions:
1) What is this tlsf memory type ?
2) Where can I find some documentation about it ? How does it works?
3) Why dlopentest (with Xenomai lib/API) is working only with tlsf memory type?
4) How to make this test successful normally without any localmem?
5) Currently, if there is any issue with dlopen, please point me. I
can work on it....


Thanks,
Pintu
