Ok, legat de la picarea testului de insmod, ai zis ca ar putea fi deoarece
eu interceptez exit_group(), si insmod returneaza o prostie. Similar pot
gandi ca si grep va retruna prostii(si pica toate testele, desi log-ul e
bun).
Totusi, interceptarea o fac ceva de genul asta:
long (*old_exit_group)(int) = NULL;
asmlinkage long my_exit_group(int error_code){
//[...]
return old_exit_group(error_code);
}
//[...]
static int sci_init(void)
{
//[...]
old_exit_group = sys_call_table[__NR_exit_group];
sys_call_table[__NR_exit_group] = my_exit_group;
//[...]
}
Nu ar trebui ca apelul catre old_exit_group sa functioneze normal?
