Pbap object and session are splitted in this patch. Reason is that
obex firstly makes disconnect of service_data, which corresponds to
session in pbap, and than it closes object, which also corresponds
to session in pbap.
When the session is disconnected, it also deallocates memory. When
obex closes the object, it is trying to dereference the deallocated
memory in order to free pbap->buffer data.
Here object and session are separated, while pointers are created to
make one-to-one mapping. Pbap object is created in vobject_..._open
functions. Session and object are handled separately when freed.

The patch has been pushed upstream. Thanks.

Object and session data is separated in PBAP plugin. Reason is that
when OBEX session firstly makes disconnect of service_data, which
corresponds to session in pbap.c, it than closes object, which also
corresponds to session in pbap.c.
Memory is deallocated after PBAP session is disconnected. When OBEX
driver closes the object, it is trying to dereference the deallocated
memory in order to free pbap->buffer data.
Here object and session are separated, while pointers are created to
make one-to-one mapping. pbap_object is created in vobject_..._open
functions after query to tracker submitted. Session and object are
handled separately when freed.

1.7.0.4
Object and session data is separated in PBAP plugin. Reason is that
when OBEX session firstly makes disconnect of service_data, which
corresponds to session in pbap.c, it than closes object, which also
corresponds to session in pbap.c.
Memory is deallocated after PBAP session is disconnected. When OBEX
driver closes the object, it is trying to dereference the deallocated
memory in order to free pbap->buffer data.
Here object and session are separated, while pointers are created to
make one-to-one mapping. pbap_object is created in vobject_..._open
functions after query to tracker submitted. Session and object are
handled separately when freed.
