 are difficult, low bandwidth, fragile, and are considered low risk.
 
+Note that, despite "Bounds Check Bypass" name, Spectre variant 1 is not
+only about user-controlled array bounds checks.  It can affect any
+conditional checks.  The kernel entry code interrupt, exception, and NMI
+handlers all have conditional swapgs checks.  Those may be problematic

+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+   An attacker can train the branch predictor to speculatively skip the
+   swapgs path for an interrupt or exception.  If they initialize
+   the GS register to a user-space value, if the swapgs is speculatively
+   skipped, subsequent GS-related percpu accesses in the speculation
+   window will be done with the attacker-controlled GS value.  This
+   could cause privileged memory to be accessed and leaked.
+
+   For example:
+

+         swapgs
+     mov %gs:<percpu_offset>, %reg
+     mov (%reg), %reg1

+   When coming from user space, the CPU can speculatively skip the
+   swapgs, and then do a speculative percpu load using the user GS
+   value.  So the user can speculatively force a read of any kernel
+   value.  If a gadget exists which uses the percpu value as an address
+   in another load/store, then the contents of the kernel value may
+   become visible via an L1 side channel attack.

 1. Kernel mitigation
 ^^^^^^^^^^^^^^^^^^^^
 
+Spectre variant 1
+~~~~~~~~~~~~~~~~~
+
    For the Spectre variant 1, vulnerable kernel code (as determined
    by code audit or scanning tools) is annotated on a case by case
    basis to use nospec accessor macros for bounds clipping :ref:`[2]
    <spec_ref2>` to avoid any usable disclosure gadgets. However, it may
    not cover all attack vectors for Spectre variant 1.
 
+   Copy-from-user code has an LFENCE barrier to prevent the access_ok()
+   check from being mis-speculated.  The barrier is done by the
+   barrier_nospec() macro.
+
+   For the swapgs variant of Spectre variant 1, LFENCE barriers are
+   added to interrupt, exception and NMI entry where needed.  These
+   barriers are done by the FENCE_SWAPGS_KERNEL_ENTRY and
+   FENCE_SWAPGS_USER_ENTRY macros.
