Bug 139597 – Skype 1.3.0.30-rc1 issue (exec stacks?)

• Product: Gentoo Linux
• Status: RESOLVED WORKSFORME

[Description Jacopo 2006-07-07 13:30:13 UTC]

Seems like the new version of skype runs only under root account;
if used under normal user account it freezes trying to make a call.
Googling around and on skype forum seems like this is a common gentoo issue, while other distro are ok. I noticed this warning while emerging it:


QA Notice: the following files contain executable stacks
 Files with executable stacks will not work properly (or at all!)
 on some architectures/operating systems.  A bug should be filed
 at http://bugs.gentoo.org/ to make sure the file is fixed.
 For more information, see http://hardened.gentoo.org/gnu-stack.xml
 Please include this file in your report:
 /var/tmp/portage/skype-1.3.0.30-r1/temp/scanelf-execstack.log
"--- --- RWX opt/skype/skype"

I think this may be the case, anyway I already noticed this to skype people to see what they think about it.

We definitely can't fix the executable stacks, go ask upstream to do it. I really doubt it has anything to do w/ that, but rather could be caused by broken sound device permissions on your system.

[Comment 2 Gustavo Felisberto (RETIRED) 2006-07-07 17:41:49 UTC]

Can you please give more details? And links to those places (attention that skype 1.2 and 1.3 are very diferent in sound access).

Also you configured skype to use alsa or oss?

[Comment 3 gfdsa 2006-07-23 07:32:57 UTC]

configured to use alsa
did a lot of stracing, fixed all EACCs
checked limits
compared all I can find with a functional ubuntu installation
have no clue where to dig

doesn't really seem to be sound related, or more specific "alsa related"

Cant duplicate this.
