Summary: sofsip-cli core dumps processing "fake" nua_i_notify
Initial Comment:
sofsip-cli-0.10.1:
If there is no NOTIFY received after SUBSCRIBE, the
sofia sip core triggers "fake" nua_i_notify "Early
Subcsription Timeouts" (after 32 seconds). The client
is not able to process the event due to the sip
parameter dereferenced before assert, as the parameter
value is NULL in this case.
void ssc_i_notify(nua_t *nua, ssc_t *ssc,
nua_handle_t *nh, ssc_oper_t *op, sip_t const
*sip,
tagi_t tags[])
{
sip_from_t const *from = sip->sip_from;
sip_event_t const *event = sip->sip_event;
sip_content_type_t const *content_type =
sip->sip_content_type;
sip_payload_t const *payload = sip->sip_payload;
assert(sip);
if (op)
....
To prevent the seg. fault sip parameter should be
checked before (like in the following example):
void ssc_i_notify(nua_t *nua, ssc_t *ssc,
nua_handle_t *nh, ssc_oper_t *op, sip_t const
*sip,
tagi_t tags[])
{
if (!sip) {
printf("%s: NOTIFY
sip=%p,nh=%p,op=%p\n",ssc->ssc_name, sip, nh, op);
return;
}
sip_from_t const *from = sip->sip_from;
sip_event_t const *event = sip->sip_event;
sip_content_type_t const *content_type =
sip->sip_content_type;
sip_payload_t const *payload = sip->sip_payload;
if (op)
....

Michal Matyska
