Bug 100697 – asterisk fails to load modules when compiled with ssp

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Roy Marples (RETIRED) 2005-07-29 05:52:26 UTC]

Asterisk fails to load modules when compiled with ssp (default for hardened
profile). Compiling without ssp via gcc-config makes things work.

The issue appears to be that adsi.h does not mark it's functions as weak references.

Here's a sample log message

Jul 29 13:09:32 WARNING[3540]: /usr/lib/asterisk/modules/res_features.so:
undefined symbol: adsi_available
Jul 29 13:09:32 WARNING[3540]: Loading module res_features.so failed!

Created attachment 64611 [details, diff]
asterisk-weak-reference.patch

This patch marks extern functions in adsi.h as weak, which enables the module
to load correctly when compiled with ssp

took some time to get a hardened chroot up and running,
works fine here too, applied to 1.0.8 and 1.0.9, thanks a lot for discovering
the root cause and creating the patch :)

Thanks should really goto solar as he kinda pointed me in the right direction :)
