To clarify, did you only test those versions, or did you also try older versions and they worked? Thanks for testing different kernel versions. This issue was reported in IRC too, but we didn't manage to trace it down to kernel differences yet. > Looking at the code there is a few functions that assume UNIX sockets: > > pa_iochannel_write_with_creds() > pa_iochannel_write_with_fds() Or rather, the functions assume that setting creds works ("works" as in doesn't result in an error) on IP sockets as well (or at least pa_iochannel_write_with_creds() assumes that - I haven't looked at the call paths for pa_iochannel_write_with_fds()). It seems that the kernel has stopped accepting creds for IP sockets? That behaviour would make sense to me, although it might be against the "never break userspace" rule that the kernel tries to follow. In any case, I'll write a patch that avoids calling the aforementioned functions on IP sockets.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
