hi guys,
I am writing a kernel module where I am trying to
access the task_structs. Now I have tried this using
various mathods.
1) Using the pidhash array.
Here when I do a insmod I get a unresolved
symbol. I have included sched.h and also done an
extern on struct task_struct pidhash[PIDHASH_SZ] as it
is declared in fork.c
2) Directly accessing the location of pidhash as
seen in System.map.
Here when the pidhash_fn hashes the supplied
pid, the particular location into which it indexes is
NULL. I obtain the pid of the process after a "ps
-aux"
3) Starting from the init_task.
Here the next task after the init task is found
to be NULL.
Could some one help me in this matter.
-vangough.
