Bug#318189: asterisk-oh323: chan_oh323.so cannot find symbol and Asterisk crashes

[Juan Jose Comellas]

Package: asterisk-oh323
Version: 0.6.6pre3-3
Severity: grave
Justification: renders package unusable

The asterisk-oh323 package version 0.6.6pre3-3 was linked expecting the
ast_smoother_feed symbol to be in the /usr/sbin/asterisk executable. The
problem is that the symbol is present as __ast_smoother_feed and thus
chan_oh323.so does not find it. Because of this, when Asterisk starts
and tries to load the chan_oh323.so module it aborts because the symbol
cannot be found.

The following error message is logged to /var/log/asterisk/messages when
this happens:

Jul 13 19:37:26 WARNING[2373]: /usr/lib/asterisk/modules/chan_oh323.so:
undefined symbol: ast_smoother_feed
Jul 13 19:37:26 WARNING[2373]: Loading module chan_oh323.so failed!

The problem can be seen by running these commands:

# objdump -T /usr/sbin/asterisk | grep ast_smoother_feed
08054698 g    DF .text  000001bd  Base        __ast_smoother_feed

~# objdump -T /usr/lib/asterisk/modules/chan_oh323.so | grep
ast_smoother_feed
00000000      D  *UND*  00000000              ast_smoother_feed

Looking at the Asterisk headers it looks like the asterisk package is at
fault, because in line 378 of /usr/include/asterisk/frame.h the
function's prototype is:

extern int ast_smoother_feed(struct ast_smoother *s, struct ast_frame *f);

A workaround to this problem without uninstalling asterisk-oh323 is to
add the following line to /etc/asterisk/modules.conf:

noload => chan_oh323.so
