| |
Hi All, Based on the feedback obtained from the community, I have have address the below issues in the Kprobes.
1) When patching the original instruction with the break instruction, we need to preserve the original qualifying predicate for all instruction except for some special instruction like (qp) cmp.crel.ctype p1,p2=r1,r2 where ctype == unc, which always needs to be emulated irrespective of original qp.
2) Fail register_kprobes() for unsupported instruction. Currently Kprobes of some speculation chk instruction and mov r1=ip kind of instructions are not supported. Hence when user tries to register kprobes on these instruction, fail register_kprobe() instead of handling badly.
Comments welcome.
Thanks, Anil Keshavamurthy --
