[Bug 1574270] Re: applications segfault systematically with tsocks
All, Thanks to the testers; thanks to the up-voters! It feels good not to be alone! ;-) However, I'm not sure what to do with this bug report now... The maintainer is in Cc, the Ubuntu Review Team is in Cc, the last uploader is in Cc. Yet, no reply so far. I know the tsocks code base is, to say the least, not the best I had to deal with; yet the reasons are pretty well explained and the patch itself pretty simple. It's a wonder the bug did not get exposed until only recently; it's been latent for all those years. I *am* ready to rework the patch if it is deemed to be not correct, but I can't do that without feedback. Heck, I would even consider volunteering to handle this package for the foreseable future if that would help (but I am not used to packaging; I'd need directions quite often). Quid? Regards, Yann E. MORIN. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1574270 Title: applications segfault systematically with tsocks To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/tsocks/+bug/1574270/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Markus, All, Weird that it did not work for you. I retested it just right now, and it worked for me. Note however that I did a mistake when typing the command in the report: dpkg-buildpacakge is misspelled, it should be dpkg-buildpackage. Regards, Yann E.

Dear Tamas, Dear Ubuntu Review Team, It's been more than a month that I have posted a proposal to fix this bug. In the meantime, I have tested this extensively (as *everything* gets out of my machine via tsocks) and I have had no issue at all. with the proposed patch. Can we at least get a status on this bug, even it is just a "won't fix" or "don't care" or whatever, please? ;-) Thanks! Regards, Yann E. MORIN PS.

Brendan, That's because the attached patch expects the bundled patches are already applied. Here's how I did (as non-root): $ sudo apt-get build-dep tsocks [--snip--] $ apt-get source tsocks [--snip--] $ cp 07_init.dpatch tsocks-1.8beta5/debian/patches/ $ cd tsocks-1.8beta5/ $ dpkg-buildpacakge -us -uc [--snip--] $ cd .. $ sudo apt-get purge tsocks $ sudo dpkg --install tsocks_1.8beta5-9.3_amd64.deb Also, to avoid tsocks being re-installed from the repository every time I run "make dist-upgrade", I simply uninstalled it before installing my locally-built tsocks (hence the "apt-get purge tsocks in the commands above). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1574270 Title: applications segfault systematically with tsocks To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/tsocks/+bug/1574270/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1574270] Re: applications segfault systematically with tsocks
Mario, The "official" upstream tsocks has not done any release since October 2002, that is almost 14 years ago. Besides, there does nto seem to be any publicly available repository of any kind (no svn, no cvs or anything that was current at the time). I'm not sure it makes sense to send a patch to a dead project. If we were to consider Debian as the new upstream, I can't really report a bug there, as I don't use Debian so can't check if the bug also applies to them... However, the maintainer for this package in Ubuntu is also the maintainer for the same package in Debian. So, hopefully, he'd notice this bug! ;-) (Cc-ing Tamas now, so he does notice it.) In the meantime, it would be nice if you could also test on your side with your use-cases, so as to get a bit more confidence in the patch (which I only tested in my own use-case, and only lightly tested at that...).

[Bug 1574270] Re: applications segfault systematically with tsocks
I managed to make it work with the attached patch. This is probably not a correct patch, but it at least makes it work, and can serve as a base for a correct patch. In the end, it happens that some libraries (like openssl) are initialised before those in LD_PRELOAD (which is really weird as ld.so does not document this behaviour). So, tsocks not being initialised, the wrapper functions were calling functions via un-initialised function pointers. ** Attachment added: "Be sure to always intialise function pointers" https://bugs.launchpad.net/ubuntu/+source/tsocks/+bug/1574270/+attachment/4653856/+files/07_init.dpatch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1574270 Title: applications segfault systematically with tsocks To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/tsocks/+bug/1574270/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1574270] Re: applications segfault systematically with tsocks
After a bit more investigation, I hacked tsocks to spit out debug log in its _init() function: FILE *f = fopen( "/home/me/tsocks.msg", "a+" ); fprintf( "[%s] Hello world\n", program_invocation_name ); fclose( f ); However, when running: $ tsocks ssh machine Segmentation fault The .msg file is *not* created at all! So, it seems something is trying to initialise openSSL before calling the _init() from tsocks... So, I tried with another program *not* linked with openSSL. I used curl, which is linked with GnuTLS: $ curl https://example.com/ [works!] Conclusion: openSSL does get initialised before tsocks. That's really weird, as tsocks is in LD_PRELOAD, so should come before any shared library from a NEEDED tag. /me is now investigating the linker documentation to understand what's goign on... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1574270 Title: applications segfault systematically with tsocks To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/tsocks/+bug/1574270/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1082906] [NEW] hibernate item does not show up in menu when no swap active
Public bug reported:
When no swap is active, the 'hibernate' item does not show up in the
/system/ menu.
I manually verified that hibernation works on my machine (using pm-
hibernate), and it does.
As I am using an SSD, I do not use any swap at all (I have enough RAM).
However, I have an inactive swap partition that gets activated by a pm hook:
cat /etc/pm/sleep.d/00-swap
#!/bin/sh
swap_device=$( awk '$0 ~ /^#/ { next; }
$3==swap {
printf( %s\n, $1 );
}' /etc/fstab )
case ${1} in
hibernate)
# Create and activate a clean swap
mkswap ${swap_device}
swapon ${swap_device}
;;
thaw)
swapoff ${swap_device}
# Forget the old SWSUSP image after resuming
dd if=/dev/zero of=${swap_device} bs=1048576 count=4
;;
esac
Note: I need to cleanup the previous SWSUSP image, so the kernel does
not pick it up after a normal, non-hibernate boot.
If I manually activate the swap partition, then 'hibernate' shows up in
the system menu. If the swap partition is not active, but only
formatted, hibernate is not available; the swap has to be active.
It somehow makes sense to disable hibernate if there is no swap, but
using swap on an SSD risks wearing out the SSD very fast.
