Subject: perl 5.24 segfaults during a dpkg -i of cmanager (and other packages)

Date: Fri, 21 Apr 2017 13:10:44 -0400

Package: perl
Version: 5.24.1-2


When installing packages right after a fresh stretch install, perl started to
segfault.

EG:

Setting up cgmanager (0.41-2) ...

I used dpkg + wget, downgraded via --force-all both perl and perl-base to jessie's version.

The problem went away, and I was able to install cmanager without a segfault.

System can be down a few days, so I've left it in this state.  I can test / debug / etc.

Thanks

Hi Brad,

Thanks for filing this bug.

Could you perhaps include the following information:

 * Which architecture are you using?  If you have multi-arch enabled,
   please list the architecture of the perl packages (e.g. in the form
   of "dpkg -l" if you don't mind including a list of all packages
   installed)

 * Does perl segfault in general or does it "only" happen when you run
   dpkg/apt?
   - e.g. try running "dpkg-architecture" (if you have dpkg-dev
     installed)

 * If you can reproduce the segfault directly, can you provide a
   backtrace with symbols? NB: you will probably need to download some
    of the debug symbols from the new debug archive (see [1])

Thanks,
~Niels

PS: Please keep me CC'ed in replies.

You mention "other packages" in your bug report; do you happen to
remember which ones?
Do the problems persist if you upgrade to stretch's perl again?

amd64, nothing else.

So far, only when running apt/dpkg.  And, only at specific times (more to
follow, as per Gregor's request)

I can't directly, and strace wasn't very helpful in tracing perl via
dpkg -- even with -f.

EG:

strace -s10024 -f -i -y  -o /tmp/bah dpkg -D10000 -i cgmanager_0.41-2_amd64.deb

4848  read(4, "package strict;\n\n$strict::VERSION = \"1.11\";\n\nmy ( %bitmask, %explicit_bitmask );\n\nBEGIN {\n

As per Gregor's request, here's what happened:

- installed a fresh copy of stretch on an older generation (fully amd64 capable) AMD box

- install went fine.  Installed it today, using V3 of the installer

- tasksel was ONLY 'ssh' and below it 'standard system utilities'

- post boot, modified /etc/network/interfaces, then:

- apt-get installed vim lsof

- installed moreutils

- installed inetutils-tools

- purged inetutils-tools

- installed net-tools

- created /etc/apt/preferences.d/systemd, with contents:

Package: systemd
Pin: release *
Pin-Priority: -1


Package: *systemd*
Pin: release *
Pin-Priority: -1

Package: systemd:i386
Pin: release *
Pin-Priority: -1

Package: systemd:amd64

- apt-get install sysvinit-core

This also did:

Remove: systemd-sysv:amd64 (232-22), libpam-systemd:amd64 (232-22)

During install:

- at this point, I "did a few things".  EG, dmesg, looked at logs, did an apt-get update...

- after more mucking about, did: mv /etc/apt/preferences.d/systemd /
  (just some place to stash it for temp)

(EG, quite a few more packages were pulled in)

- did dpkg -i --force-all perl-base_5.20.2-3+deb8u6_amd64.deb, segfault gone, as:

strace -s10024 -f -i -y  -o /tmp/bah dpkg -D10000 -i cgmanager_0.41-2_amd64.deb

succeeded.



Just now, as per your request, I restored 5.24 of both packages.

*Everything is fine now*.

Since I have just installed this system, I can very easily to a
re-install.  I can also do some tests, but before I do, I'll see of the
above kicks any ideas into mind.

If we do more tests, I'll try to get a list of files -- see if 5.20 ->
5.24 left anything extra behind, etc....

Thanks

Hi,

Can you reproduce the segfault reliably by running:

 "deb-systemd-helper unmask cgmanager.service >/dev/null"

With Perl 5.24?

Thanks,
~Niels

Hmm.

root@newoldbe:/var/cache/apt/archives# deb-systemd-helper unmask
cgmanager.service >/dev/null /usr/bin/deb-systemd-helper was not called
from dpkg. Exiting.

No segfault.

....

Now that my system is working, I just completed the apt-get -f, made sure
sysvinit was installed, removed systemd, purged it and such.

I then did a purge of cgmanager and others (they were pulled in for some
reason with sysvinit), and tried a fresh install.  It's fine.

deb-systemd-helper still says the same as the above, with no segfault.

Please close this bug.

This box has been in service for a long time, with zero issues.

After a fresh install of stretch, this issue with perl exhibited itself.

After, all seemed quite well.  However, a week later?  SSH connections
started dropping with checksum errors.

A memtest86+ run, of 2 *days* finally showed RAM errors.  It wasn't until
the 10th or 12th run through, that they appeared.

This box had an uptime of -- well, a year prior to this upgrade.  It
seemed fine, and was a stable runner.  The bad memory was very specific
to a small part of one DIMM, so I can only assume that luck resulted in
that memspace not being used for anything I noticed.  

Sorry for the issue guys, very sorry to waste your time.

And thanks for the help.
