Segmentation fault when running ipkg after updating to latest glibc-opt_2.25-1_i686.ipk

[mitzone]

Using ipkg bootstrap on a syno i686.
Thanks,
Mihai.

Hi Mihai,

ipkg is a static binary, so it doesn't depend on glibc-opt, or any other shared libraries, so glibc-opt version doesn't matter at all here. ipkg should work on any x86 (or x86_64) Linux 3.2+ (what's the output of uname -a on your box?). Also, if it worked prior to the upgrade, I don't see how any library upgrade could break ipkg. btw, I have an Intel Syno too (DS412+), and I'm not experiencing any segfaults.

Hello,
Thanks for your reply.
I manually installed libnsl - 2.21-3 and glibc-opt - 2.21-4. Keeping those at this version does not brake things.

Here's the output f uname -a:

Linux corevault-1 3.10.102 #15152 SMP Fri Oct 6 18:13:57 CST 2017 x86_64 GNU/Linux synology_bromolow_3615xs

Also, I attached the list of packages currently installed. Everything works fine. I'll test an ipkg upgrade tomorrow and will let you know. Any idea if ldd will be available?

Mihai,

Can you please be more specific as to what segfaults exactly? Like I said, ipkg doesn't rely on libnsl or glibc-opt, so it's not ipkg, right? Some other package? Nothing segfaults on my side.

ldd is available in the feeds: it's a bash script for glibc targets.

If I install libnsl and glibc-opt (latest versions available) then just by running ipkg with no options, I get a Segmentation fault (core dumped) error. As I said, I installed the previous N-1 versions of those 2 packages and it's working as expected. Maybe it's just on my side if noone but me said anything until now. Cheers, Mihai.

Hm, looks like you're using some dynamically linked ipkg. Maybe, it's old Optware ipkg? Let's try the current bootstrap script:

wget -O - http://ipkg.nslu2-linux.org/optware-ng/bootstrap/buildroot-i686-bootstrap.sh | sh

It installs static ipkg:

# file /opt/bin/ipkg
/opt/bin/ipkg: ELF 32-bit LSB executable, Intel 80386, version 1 (GNU/Linux), statically linked, for GNU/Linux 2.6.32, stripped

I think you are corect. I have a bootstrap script I always used. I just changed the sources to point to yours after the script ran. I'll give it a go and will let you know. Thanks, Mihai.

It's OK to use old Optware bootstrap script to do platform-specific things (like adding rc scenario to mount /volume1/@optware as /opt that syno-i686 bootstrap script does), but you should run Optware-ng bootstrap afterwards, which simply unpacks Optware-ng static ipkg (which is opkg actually) to /opt.

Hello,
I confirm that using the old script, then the new one fixes it.
Those are the steps I followed, maybe those will help others as well :

1. Ran the script located here http://ipkg.nslu2-linux.org/feeds/optware/syno-i686/cross/unstable/syno-i686-bootstrap_1.2-7_i686.xsh
   That makes sure /etc/rc.local gets updated, /opt is mounted at boot, etc, things specific to syno
2. Ran the new script located at http://ipkg.nslu2-linux.org/optware-ng/bootstrap/buildroot-i686-bootstrap.sh
3. Edit /opt/etc/ipkg/cross-feed.conf and delete the old sources.
4. Ran ipkg update, made sure only optware-ng sources are used.
5. Installed my ipkg packages.

Thanks again for your help.

Hi Mihai,

Your steps look god except that step 3. is not needed: /opt/etc/ipkg/cross-feed.conf is not used, you can either ignore it, or delete it altogether.

You're welcome 😃
