git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx Pull still more SPDX updates from Greg KH: "Another round of SPDX updates for 5.2-rc6 Here is what I am guessing is going to be the last "big" SPDX update for 5.2. It contains all of the remaining GPLv2 and GPLv2+ updates that were "easy" to determine by pattern matching. The ones after this are going to be a bit more difficult and the people on the spdx list will be discussing them on a case-by-case basis now. Another 5000+ files are fixed up, so our overall totals are: Files checked: 64545 Files with SPDX: 45529 Compared to the 5.1 kernel which was: Files checked: 63848 Files with SPDX: 22576 This is a huge improvement. Also, we deleted another 20000 lines of boilerplate license crud, always nice to see in a diffstat" * tag 'spdx-5.2-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx: (65 commits) treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 507 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 506 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 505 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 504 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 503 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 502 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 501 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 500 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 499 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 498 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 497 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 496 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 495 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 491 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 490 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 489 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 488 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 487 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 486 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 485 ...
2019-06-20KVM: nVMX: reorganize initial steps of vmx_set_nested_statePaolo Bonzini1-12/+20
Commit 332d079735f5 ("KVM: nVMX: KVM_SET_NESTED_STATE - Tear down old EVMCS state before setting new state", 2019-05-02) broke evmcs_test because the eVMCS setup must be performed even if there is no VMXON region defined, as long as the eVMCS bit is set in the assist page. While the simplest possible fix would be to add a check on kvm_state->flags & KVM_STATE_NESTED_EVMCS in the initial "if" that covers kvm_state->hdr.vmx.vmxon_pa == -1ull, that is quite ugly. Instead, this patch moves checks earlier in the function and conditionalizes them on kvm_state->hdr.vmx.vmxon_pa, so that vmx_set_nested_state always goes through vmx_leave_nested and nested_enable_evmcs.

2019-06-19KVM: x86: Modify struct kvm_nested_state to have explicit fields for dataLiran Alon1-21/+21
Improve the KVM_{GET,SET}_NESTED_STATE structs by detailing the format of VMX nested state data in a struct. In order to avoid changing the ioctl values of KVM_{GET,SET}_NESTED_STATE, there is a need to preserve sizeof(struct kvm_nested_state). This is done by defining the data struct as "data.vmx[0]". It was the most elegant way I found to preserve struct size while still keeping struct readable and easy to maintain. It does have a misfortunate side-effect that now it has to be accessed as "data.vmx[0]" rather than just "data.vmx". Because we are already modifying these structs, I also modified the following: * Define the "format" field values as macros. * Rename vmcs_pa to vmcs12_pa for better readability.
