[RFC][PATCH 0/4] x86, mpx: Support larger address space (MAWA)

Kirill is chugging right along getting his 5-level paging[1] patch set ready to be merged. I figured I'd share an early draft of the MPX support that will to go along with it. Background: there is a lot more detail about what bounds tables are in the changelog for fe3d197f843. But, basically

[RFC][PATCH 2/4] x86, mpx: update MPX to grok larger bounds tables

As mentioned repeatedly, larger address spaces mean larger MPX bounds tables. The MPX code in the kernel needs to walk these tables in order to populate them on demand as well as unmap them when memory is freed. This updates the bounds table walking code to understand how to walk the larger

[PATCH V2 1/2] netfilter: ctnetlink: Fix regression in CTA_STATUS processing

The libnetfilter_conntrack userland library always sets IPS_CONFIRMED when building a CTA_STATUS attribute. If this toggles the bit from 0->1, the parser will return an error. On Linux 4.4+ this will cause any NFQA_EXP attribute in the packet to be ignored. This breaks conntrackd's userland

[PATCH V2 2/2] netfilter: ctnetlink: Fix regression in CTA_HELP processing

Prior to Linux 4.4, it was usually harmless to send a CTA_HELP attribute containing the name of the current helper. That is no longer the case: as of Linux 4.4, if ctnetlink_change_helper() returns an error from the ct->master check, processing of the request will fail, skipping the NFQA_EXP
