Hi Todd,
I love your patch! Perhaps something to improve:
[auto build test WARNING on staging/staging-testing]
[also build test WARNING on v4.19-rc1 next-20180828]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system]

this. This is for 4.18.0.
It is a very trivial patch, but this is my first actu

This is an extension of commit b506a9d08bae ("x86: code clarification patch
to Kprobes arch code"). As that commit explains, even though
kprobe_running() can't be called with preemption enabled, you don't have to
disable preemption - if preemption is on, you can't be in a kprobe.
Also, use X86_TRA
This is the third version of "[RFC PATCH 1/2] x86: WARN() when uaccess
helpers fault on kernel addresses".
Changes since v2:
- patch 1: avoid unnecessary branch on return value and split up the
checks (Borislav Petkov)
- patch 5: really plumb the error code through to the handlers (Andy)
- p
Currently, most fixups for attempting to access userspace memory are
handled using _ASM_EXTABLE, which is also used for various other types of
fixups (e.g. safe MSR access, IRET failures, and a bunch of other things).
In order to make it possible to add special safety checks to uaccess fixups
(in p
The opaque plumbing of #GP from do_general_protection() through
notify_die() into kprobe_exceptions_notify() makes it hard to understand
what's going on.

This removes the call into exception fixup that was added in
commit c28f896634f2 ("[PATCH] kprobes: fix broken fault handling for
x86_64").
On X86, kprobe_fault_handler() is called from two places:
do_general_protection() (for #GP) and kprobes_fault() (for #PF).
In both paths, the fixup_exception(
There have been multiple kernel vulnerabilities that permitted userspace to
pass completely unchecked pointers through to userspace accessors:
- the waitid() bug - commit 96ca579a1ecc ("waitid(): Add missing
access_ok() checks")
- the sg/bsg read/write APIs
- the infiniband read/write APIs
Test whether the kernel WARN()s when, under KERNEL_DS, a bad kernel pointer
is used as "userspace" pointer. Should normally be used in "DIRECT" mode.
