[PATCH v3 2/2] kprobes: initialize probed_mod to NULL

When check_kprobe_address_safe() return fail, the probed_mod should be set to NULL, because no module refcount held. And we initialize probed_mod to NULL in register_kprobe() for the same reason. Signed-off-by: Zhou Chengming --- kernel/kprobes.c | 3 ++- 1 file

[PATCH v3 1/2] kprobes: avoid the kprobe being re-registered

Changes: - We should put the modifies of the kprobe after the re-reg check. - And then the address_safe check. Old code use check_kprobe_rereg() to check if the kprobe has been registered already, but check_kprobe_rereg() will release the kprobe_mutex then, so maybe two paths will pass the check

Sorry but I messed up sending the patch and it ended up with two entries in the From header field, which git am will parse as: "Author: sa...@posteo.net " rather than: "Author: Eduard Sanou " The right From header should be the one seen in this email.
