Thanks for pointing this out, probably this was the problem, I'll try
later because for now, I switched to 32-bit jid_t and that part works
but there's other similar problem now:
+int
+setjlimit(struct thread *td, struct setjlimit_args *uap)
+{
+ struct jobentry *jp;
+
+ /* sanity check */
+ if (uap->resource>= JLIMIT_NLIMITS) {
+ td->td_retval[0] = -1;
+ return (EINVAL);
+ }
...
The rest is just generated code with make sysent.
I call this with resource parameter set to JLIMIT_NUMPROC (whose value
is 3) and then inside the function it is seen as 869787392, so I always
get EINVAL. In this case resource is just a normal int so I don't know
what's going wrong.
