I'm announcing the release of the 5.1.4 kernel.
All users of the 5.1 kernel series must upgrade.
The updated 5.1.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-5.1.y
and can be browsed at the normal kernel.org git web browser:
https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary
thanks,
greg k-h

The mitigation is invoked in prepare_exit_to_usermode() which covers

+ all but one of the kernel to user space transitions. The exception
+ is when we return from a Non Maskable Interrupt (NMI), which is
+ handled directly in do_nmi().
- - Non Maskable Interrupt (NMI):
-
- Access to sensible data like keys, credentials in the NMI context is
- mostly theoretical: The CPU can do prefetching or execute a
- misspeculated code path and thereby fetching data which might end up
- leaking through a buffer.
-
- But for mounting other attacks the kernel stack address of the task is
- already valuable information. So in full mitigation mode, the NMI is
- mitigated on the return from do_nmi() to provide almost complete
- coverage.
-
- - Double fault (#DF):
-
- A double fault is usually fatal, but the ESPFIX workaround, which can
- be triggered from user space through modify_ldt(2) is a recoverable
- double fault. #DF uses the paranoid exit path, so explicit mitigation
- in the double fault handler is required.
-
- - Machine Check Exception (#MC):
-
- Another corner case is a #MC which hits between the CPU buffer clear
- invocation and the actual return to user. As this still is in kernel
- space it takes the paranoid exit path which does not clear the CPU
- buffers. So the #MC handler repopulates the buffers to some
- extent. Machine checks are not reliably controllable and the window is
- extremly small so mitigation would just tick a checkbox that this
- theoretical corner case is covered. To keep the amount of special
- cases small, ignore #MC.
-
- - Debug Exception (#DB):
-
- This takes the paranoid exit path only when the INT1 breakpoint is in
- kernel space. #DB on a user space address takes the regular exit path,
- so no extra mitigation required.
+ (The reason that NMI is special is that prepare_exit_to_usermode() can
+ enable IRQs. In NMI context, NMIs are blocked, and we don't want to
+ enable IRQs with NMIs blocked.)
