Pull kvm updates from Paolo Bonzini: "The bulk of the changes here is a largish change to guest_memfd, delaying the clearing and encryption of guest-private pages until they are actually added to guest page tables. This started as "let's make it impossible to misuse the API" for SEV-SNP; but then it ballooned a bit. The new logic is generally simpler and more ready for hugepage support in guest_memfd. Summary: - fix latent bug in how usage of large pages is determined for confidential VMs - fix "underline too short" in docs - eliminate log spam from limited APIC timer periods - disallow pre-faulting of memory before SEV-SNP VMs are initialized - delay clearing and encrypting private memory until it is added to guest page tables - this change also enables another small cleanup: the checks in SNP_LAUNCH_UPDATE that limit it to non-populated, private pages can now be moved in the common kvm_gmem_populate() function - fix compilation error that the RISC-V merge introduced in selftests" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: KVM: x86/mmu: fix determination of max NPT mapping level for private pages KVM: riscv: selftests: Fix compile error KVM: guest_memfd: abstract how prepared folios are recorded KVM: guest_memfd: let kvm_gmem_populate() operate only on private gfns KVM: extend kvm_range_has_memory_attributes() to check subset of attributes KVM: cleanup and add shortcuts to kvm_range_has_memory_attributes() KVM: guest_memfd: move check for already-populated page to common code KVM: remove kvm_arch_gmem_prepare_needed() KVM: guest_memfd: make kvm_gmem_prepare_folio() operate on a single struct kvm KVM: guest_memfd: delay kvm_gmem_prepare_folio() until the memory is passed to the guest KVM: guest_memfd: return locked folio from __kvm_gmem_get_pfn KVM: rename CONFIG_HAVE_KVM_GMEM_* to CONFIG_HAVE_KVM_ARCH_GMEM_* KVM: guest_memfd: do not go through struct page KVM: guest_memfd: delay folio_mark_uptodate() until after successful preparation KVM: guest_memfd: return folio from __kvm_gmem_get_pfn() KVM: x86: disallow pre-fault for SNP VMs before initialization KVM: Documentation: Fix title underline too short warning KVM: x86: Eliminate log spam from limited APIC timer periods

uretprobe: change syscall number, again

2024-08-02T13:18:49Z

Despite multiple attempts to get the syscall number assignment right for the newly added uretprobe syscall, we ended up with a bit of a mess: - The number is defined as 467 based on the assumption that the xattrat family of syscalls would use 463 through 466, but those did not make it into 6.11. - The include/uapi/asm-generic/unistd.h file still lists the number 463, but the new scripts/syscall.tbl that was supposed to have the same data lists 467 instead as the number for arc, arm64, csky, hexagon, loongarch, nios2, openrisc and riscv. None of these architectures actually provide a uretprobe syscall. - All the other architectures (powerpc, arm, mips, ...) don't list this syscall at all. There are two ways to make it consistent again: either list it with the same syscall number on all architectures, or only list it on x86 but not in scripts/syscall.tbl and asm-generic/unistd.h. Based on the most recent discussion, it seems like we won't need it anywhere else, so just remove the inconsistent assignment and instead move the x86 number to the next available one in the architecture specific range, which is 335.

selftests: mptcp: join: check backup support in signal endp

2024-07-30T08:27:30Z

Before the previous commit, 'signal' endpoints with the 'backup' flag were ignored when sending the MP_JOIN. The MPTCP Join selftest has then been modified to validate this case: the "single address, backup" test, is now validating the MP_JOIN with a backup flag as it is what we expect it to do with such name. The previous version has been kept, but renamed to "single address, switch to backup" to avoid confusions. The "single address with port, backup" test is also now validating the MPJ with a backup flag, which makes more sense than checking the switch to backup with an MP_PRIO. The "mpc backup both sides" test is now validating that the backup flag is also set in MP_JOIN from and to the addresses used in the initial subflow, using the special ID 0. The 'Fixes' tag here below is the same as the one from the previous commit: this patch here is not fixing anything wrong in the selftests, but it validates the previous fix for an issue introduced by this commit ID.

selftests: mptcp: join: validate backup in MPJ

2024-07-30T08:27:30Z

A peer can notify the other one that a subflow has to be treated as "backup" by two different ways: either by sending a dedicated MP_PRIO notification, or by setting the backup flag in the MP_JOIN handshake. The selftests were previously monitoring the former, but not the latter. This is what is now done here by looking at these new MIB counters when validating the 'backup' cases: MPTcpExtMPJoinSynBackupRx MPTcpExtMPJoinSynAckBackupRx The 'Fixes' tag here below is the same as the one from the previous commit: this patch here is not fixing anything wrong in the selftests, but it will help to validate a new fix for an issue introduced by this commit ID.
