+Spectre variant 1 (swapgs)
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ 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:
+
+ ::
+
+ if (coming from user space)
+ 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.
+
+ A similar attack exists when coming from kernel space. The CPU can
+ speculatively do the swapgs, causing the user GS to get used for the
+ rest of the speculative window.
+

+
+ A spectre variant 2 attacker can :ref:`poison <poison_btb>` the branch
target buffer (BTB) before issuing syscall to launch an attack.

+~~~~~~~~~~~~~~~~~
+
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

+
+ For the swapgs variant of Spectre variant 1, LFENCE barriers are
+ added to interrupt, exception and NMI entry where needed. These
