6 mds_user_clear.
7
8 The mitigation is invoked in prepare_exit_to_usermode() which covers
9 - most of the kernel to user space transitions. There are a few exceptions
10 - which are not invoking prepare_exit_to_usermode() on return to user
11 - space. These exceptions use the paranoid exit code.
12 + all but one of the kernel to user space transitions. The exception
13 + is when we return from a Non Maskable Interrupt (NMI), which is
14 + handled directly in do_nmi().
15
16 - - Non Maskable Interrupt (NMI):
17 -
18 - Access to sensible data like keys, credentials in the NMI context is
19 - mostly theoretical: The CPU can do prefetching or execute a
20 - misspeculated code path and thereby fetching data which might end up
21 - leaking through a buffer.
22 -
23 - But for mounting other attacks the kernel stack address of the task is
24 - already valuable information. So in full mitigation mode, the NMI is
25 - mitigated on the return from do_nmi() to provide almost complete
26 - coverage.
27 -
28 - - Double fault (#DF):
29 -
30 - A double fault is usually fatal, but the ESPFIX workaround, which can
31 - be triggered from user space through modify_ldt(2) is a recoverable
32 - double fault. #DF uses the paranoid exit path, so explicit mitigation
33 - in the double fault handler is required.
34 -
35 - - Machine Check Exception (#MC):
36 -
37 - Another corner case is a #MC which hits between the CPU buffer clear
38 - invocation and the actual return to user. As this still is in kernel
39 - space it takes the paranoid exit path which does not clear the CPU
40 - buffers. So the #MC handler repopulates the buffers to some
41 - extent. Machine checks are not reliably controllable and the window is
42 - extremly small so mitigation would just tick a checkbox that this
43 - theoretical corner case is covered. To keep the amount of special
44 - cases small, ignore #MC.
45 -
46 - - Debug Exception (#DB):
47 -
48 - This takes the paranoid exit path only when the INT1 breakpoint is in
49 - kernel space. #DB on a user space address takes the regular exit path,
50 - so no extra mitigation required.
51 + (The reason that NMI is special is that prepare_exit_to_usermode() can
52 + enable IRQs. In NMI context, NMIs are blocked, and we don't want to
53 + enable IRQs with NMIs blocked.)
