<julien.grall@xxxxxxxxxx> Date: Fri Feb 2 14:19:25 2018 +0000 xen/arm32: entry: Document the purpose of r11 in the traps handler It took me a bit of time to understand why __DEFINE_TRAP_ENTRY is storing the original stack pointer in r11. It is working in pair with return_traps_entry where sp will be restored from r11. This is fine because per the AAPCS r11 must be preserved by the subroutine. So in return_from_trap, r11 will still contain the original stack pointer. Add some documentation in the code to point the 2 sides to each other.

We use the same hack as for A12/A17 to perform the vector decoding. This is based on Linux patch from the kpti branch in [1].

This patch adds initiatial skeleton code behind a new Kconfig option to enable implementation-specific mitigations against these attacks for CPUs that are affected. Most of mitigations will have to be applied when entering to the hypervisor from the guest context. Because the attack is against branch predictor, it is not possible to safely use branch instruction before the mitigation is applied. Therefore this has to be done in the vector entry before jump to the helper handling a given exception. However, on arm32, each vector contain a single instruction. This means that the hardened vector tables may rely on the state of registers that does not hold when in the hypervisor (e.g SP is 8 bytes aligned). Therefore hypervisor code running with guest vectors table should be minimized and always have IRQs and SErrors masked to reduce the risk to use them. This patch provides an infrastructure to switch vector tables before entering to the guest and when leaving it. Note that alternative could have been used, but older Xen (4.8 or earlier) doesn't have support. So avoid using alternative to ease backporting. This is part of XSA-254.
