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.

[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 1574270] Re: applications segfault systematically with tsocks
There is a (vey old!) related bug in the Debian bug tracker: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=576301 There are two patches floating in that bug report, but they were never made part of any tsocks relase: https://bugs.debian.org/cgi-bin/bugreport.cgi?msg=5;att=1;filename=tsocks_fixpoll.patch;bug=576301 https://bugs.debian.org/cgi-bin/bugreport.cgi?filename=fix_poll.patch;att=1;bug=576301;msg=15 However, of the two patches, it is not obvious which is the correct solution; besides, they touch the exact same part of the code...
