Rao <naveen.n.rao@linux.vnet.ibm.com> # Date: Wed May 19 16:17:17 2021 +0530 # # powerpc/kprobes: Fix validation of prefixed instructions across page boundary # # When checking if the probed instruction is the suffix of a prefixed # instruction, we access the instruction at the previous word. If the # probed instruction is the very first word of a module, we can end up # trying to access an invalid page. # # Fix this by skipping the check for all instructions at the beginning of # a page. Prefixed instructions cannot cross a 64-byte boundary and as # such, we don't expect to encounter a suffix as the very first word in a # page for kernel text. Even if there are prefixed instructions crossing # a page boundary (from a module, for instance), the instruction will be # illegal, so preventing probing on the suffix of such prefix instructions # isn't worthwhile. # # Fixes: b4657f7650ba ("powerpc/kprobes: Don't allow breakpoints on suffixes") # Cc: stable@vger.kernel.org # v5.8+ # Reported-by: Christophe Leroy <christophe.leroy@csgroup.eu> # Signed-off-by: Naveen N.
