2020-04-12MAINTAINERS: sort field names for all entriesLinus Torvalds1-1974/+1974
This sorts the actual field names too, potentially causing even more chaos and confusion at merge time if you have edited the MAINTAINERS file. But the end result is a more consistent layout, and hopefully it's a one-time pain minimized by doing this just before the -rc1 release. This was entirely scripted: ./scripts/parse-maintainers.pl --input=MAINTAINERS --output=MAINTAINERS --order Requested-by: Joe Perches <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
2020-04-12MAINTAINERS: sort entries by entry nameLinus Torvalds1-820/+820
They are all supposed to be sorted, but people who add new entries don't always know the alphabet. Plus sometimes the entry names get edited, and people don't then re-order the entry. Let's see how painful this will be for merging purposes (the MAINTAINERS file is often edited in various different trees), but Joe claims there's relatively few patches in -next that touch this, and doing it just before -rc1 is likely the best time. Fingers crossed. This was scripted with /scripts/parse-maintainers.pl --input=MAINTAINERS --output=MAINTAINERS but then I also ended up manually upper-casing a few entry names that stood out when looking at the end result.

It addressed the case where a KVM guest triggers a split lock #AC and KVM reinjects it into the guest which is not prepared to handle it.

2020-04-11KVM: VMX: Extend VMXs #AC interceptor to handle split lock #AC in guestXiaoyao Li1-3/+34
Two types of #AC can be generated in Intel CPUs: 1. legacy alignment check #AC 2. split lock #AC Reflect #AC back into the guest if the guest has legacy alignment checks enabled or if split lock detection is disabled. If the #AC is not a legacy one and split lock detection is enabled, then invoke handle_guest_split_lock() which will either warn and disable split lock detection for this task or force SIGBUS on it. [ tglx: Switch it to handle_guest_split_lock() and rename the misnamed helper function. ] Suggested-by: Sean Christopherson <[email protected]> Signed-off-by: Xiaoyao Li <[email protected]> Signed-off-by: Sean Christopherson <[email protected]> Signed-off-by: Thomas Gleixner <[email protected]> Signed-off-by: Borislav Petkov <[email protected]> Acked-by: Paolo Bonzini <[email protected]> Link: https://lkml.kernel.org/r/[email protected]
2020-04-11KVM: x86: Emulate split-lock access as a write in emulatorXiaoyao Li1-1/+11
Emulate split-lock accesses as writes if split lock detection is on to avoid #AC during emulation, which will result in a panic(). This should never occur for a well-behaved guest, but a malicious guest can manipulate the TLB to trigger emulation of a locked instruction[1]. More discussion can be found at [2][3].

2020-04-11x86/split_lock: Provide handle_guest_split_lock()Thomas Gleixner2-5/+34
Without at least minimal handling for split lock detection induced #AC, VMX will just run into the same problem as the VMWare hypervisor, which was reported by Kenneth. It will inject the #AC blindly into the guest whether the guest is prepared or not. Provide a function for guest mode which acts depending on the host SLD mode. If mode == sld_warn, treat it like user space, i.e. emit a warning, disable SLD and mark the task accordingly. Otherwise force SIGBUS.
