<h3>Description</h3>

<p>Use KEMI cfgutils.lock() and cfgutils.unlock().</p>
<p>Expect native behaviour of lock() unlock().</p>
<p>Instead segfault.</p>
<h3>Troubleshooting</h3>
<p>The KEMI wrappers do not have leading sip_msg_t* argument.</p>
<p>Wrapper for lock() is cfg_lock()</p>
<p>Prototype for cfg_lock() is static int cfg_lock(str *lkey). Notice the missing sig_msg_t * first argument.</p>
<h4>Reproduction</h4>
<p>Call cfgutils.lock() cfgutils.unlock() from scripting language</p>
<h4>Debugging Data</h4>
<p>#0  0x00007fdc6e7eff32 in core_case_hash (s1=0x7fdcb88ac1a0, s2=0x0, size=16) at ../../core/hashes.h:317<br>
317                     v=(ch_icase(*p)<<24)+(ch_icase(p[1])<<16)+(ch_icase(p[2])<<8)</p>
<p>s1 is actually the sip_msg_t* not the lock key string.<br>
*s1 can actually be deferenced as <em>(sip_msg_t</em>) s1</p>
<h4>Log Messages</h4>
<h4>SIP Traffic</h4>
<h3>Possible Solutions</h3>
<p>KEMI wrappers for cfgutils.c should include dummy sip_msg_t* argument.</p>
