Yes, you must allocate with pkg, because at the end
those chunks are
freed, once the new message is built. You can also look at how other
operations with data lumps are done inside the textops module.

I assigned a const sdp string to it just for checking. Does it matter to
allocate new memory for newbody?

Hello,
how do you set newbody.s and newbody.len?

Not yet, because it is under developing, i could
paste it here right
away.
{
.
.
.
body.s = get_body(msg);
if (body.s == 0) {
LM_ERR("failed to get the message body\n");
return -1;
}
body.len = msg->len - (int) (body.s - msg->buf);
// body.len = strlen(body.s);
if (body.len == 0) {
LM_DBG("message body has zero length\n");
return -1;
}
l = del_lump(msg, body.s - msg->buf, body.len, 0);
if (!l) {
LM_ERR("del_lump failed\n");
return -1;
}
if (!insert_new_lump_after(l, newbody.s, newbody.len, 0)) {
LM_ERR("insert_new_lump_after failed\n");
return -1;
}
}
I asked related issue in this regards in Kamailio developer forum,
before. let me paste it at below. The means of other_process function
is above code.
In during developing new module in Kamailio, I encountered with
strange behaviour. I used htable module instead of linked list for
save some temporary data during call process.dependencies module to
save some information. the skeleton of my code is like thus:
if (SIP_REQUEST &METHOD_INVITE) {
insert_data_htable("some data");
other_process(msg);
}else if(SIP_REPLY){
get_data_htable("some data");
other_process(msg);
}
In other_process function i have some changes in msg's body with
message
lump.
But after i make first call in kamailio. The
kamailio was crashed.What
is it's problem?
In additional if i comment either insert/get_data_htable function or
othet_process function, i dont have this issue.
With best regards.

-- Hello,
likely you didn't allocate the pointer inserted in data lump list. Is
the code using data lumps available to look at on git?
Cheers,
Daniel
