Hello.
I tried ckrm (Class-based Kernel Resource Management) patch. I am very interested in ckrm.
However, I found the following problems.
1) Both of ckcpu and ckmem could not be applied at the same time.
I corrected the patch by hand. Is it impossible to use both at the same time?
2) When rbcemod of the module is compiled, "ckrm_cpu_change_class" becomes an undeclared symbol.
I modified kernel source kernel/class.c and export "ckrm_cpu_change_class": EXPORT_SYMBOL(ckrm_cpu_change_class);
3) The bash process newly executed dies one after another when rbadmin is executed.
The value of the argument "cls" of the "ckrm_cpu_change_class" function might be NULL. Therefore, the NULL pointer dereference occurs when it starts changing the class of the bash process.
best regards, NIWA
