Hello,
using internal msg flags is one solution for now. Probably you can push
quickly a patch starting from current code, instead of reverting --
there were few related/similar commits, as I could spot.
When I get a chance I will push a function that can tell if a pointer is
in shared memory. Still the flag could be safer to know if the value has
to be freed (pkg/shm) or not at all.
Cheers,
Daniel

Hey Daniel,
You are correct. Apologies, can you revert that commit and I will look
into it. While this works for not freeing pkg mem on a shm clone - I
see it will break in the other case. I suspect the only way to do it
now is to use msg flags?
Cheers
Jason

Hello,
the condition to do pkg_free() or not for msg->path_vec.s doesn't
seem correct. You check if path_vec.s points inside SIP message
buffer, but that doesn't happen at all. Path vector is taken from
usrloc record in cloned in pkg for sip_msg structure.
Did I misunderstand something?
Cheers,
Daniel
