break.b always sets cr.iim to 0 and the current code tries to get the break_num by decoding instruction. However, their seems to be a race condition while reading the regs->cr_iip, as on other cpu the break.b at regs->cr_iip might have been replaced with the original instruction as a result of unregister_kprobe() and hence decoding instruction to obtain break_num will result in wrong value in this case. Also includes changes to kprobes.c which now has to handle break number zero. Signed-off-by: Anil S Keshavamurthy <anil.s.keshavamurthy@intel.com> Signed-off-by: Tony Luck <tony.luck@intel.com> |
