The isomorphism neg_if_exp negates the test of a ?: conditional, making it unnecessary to have an explicit case for a negated test with the branches inverted. At the same time, we can disable neg_if_exp in cases where a different API function may be more suitable for a negated test. Finally, in the non-patch cases, E matches an expression with parentheses around it, so there is no need to mention () explicitly in the pattern. The () are still needed in the patch cases, because we want to drop them, if they are present. Signed-off-by: Julia Lawall <Julia.Lawall@inria.fr>

Pull x86 kvm updates from Paolo Bonzini: "x86: - KVM currently invalidates the entirety of the page tables, not just those for the memslot being touched, when a memslot is moved or deleted. This does not traditionally have particularly noticeable overhead, but Intel's TDX will require the guest to re-accept private pages if they are dropped from the secure EPT, which is a non starter. Actually, the only reason why this is not already being done is a bug which was never fully investigated and caused VM instability with assigned GeForce GPUs, so allow userspace to opt into the new behavior. - Advertise AVX10.1 to userspace (effectively prep work for the "real" AVX10 functionality that is on the horizon) - Rework common MSR handling code to suppress errors on userspace accesses to unsupported-but-advertised MSRs This will allow removing (almost?) all of KVM's exemptions for userspace access to MSRs that shouldn't exist based on the vCPU model (the actual cleanup is non-trivial future work) - Rework KVM's handling of x2APIC ICR, again, because AMD (x2AVIC) splits the 64-bit value into the legacy ICR and ICR2 storage, whereas Intel (APICv) stores the entire 64-bit value at the ICR offset - Fix a bug where KVM would fail to exit to userspace if one was triggered by a fastpath exit handler - Add fastpath handling of HLT VM-Exit to expedite re-entering the guest when there's already a pending wake event at the time of the exit - Fix a WARN caused by RSM entering a nested guest from SMM with invalid guest state, by forcing the vCPU out of guest mode prior to signalling SHUTDOWN (the SHUTDOWN hits the VM altogether, not the nested guest) - Overhaul the "unprotect and retry" logic to more precisely identify cases where retrying is actually helpful, and to harden all retry paths against putting the guest into an infinite retry loop - Add support for yielding, e.g. to honor NEED_RESCHED, when zapping rmaps in the shadow MMU - Refactor pieces of the shadow MMU related to aging SPTEs in prepartion for adding multi generation LRU support in KVM - Don't stuff the RSB after VM-Exit when RETPOLINE=y and AutoIBRS is enabled, i.e. when the CPU has already flushed the RSB - Trace the per-CPU host save area as a VMCB pointer to improve readability and cleanup the retrieval of the SEV-ES host save area - Remove unnecessary accounting of temporary nested VMCB related allocations - Set FINAL/PAGE in the page fault error code for EPT violations if and only if the GVA is valid. If the GVA is NOT valid, there is no guest-side page table walk and so stuffing paging related metadata is nonsensical - Fix a bug where KVM would incorrectly synthesize a nested VM-Exit instead of emulating posted interrupt delivery to L2 - Add a lockdep assertion to detect unsafe accesses of vmcs12 structures - Harden eVMCS loading against an impossible NULL pointer deref (really truly should be impossible) - Minor SGX fix and a cleanup - Misc cleanups Generic: - Register KVM's cpuhp and syscore callbacks when enabling virtualization in hardware, as the sole purpose of said callbacks is to disable and re-enable virtualization as needed - Enable virtualization when KVM is loaded, not right before the first VM is created Together with the previous change, this simplifies a lot the logic of the callbacks, because their very existence implies virtualization is enabled - Fix a bug that results in KVM prematurely exiting to userspace for coalesced MMIO/PIO in many cases, clean up the related code, and add a testcase - Fix a bug in kvm_clear_guest() where it would trigger a buffer overflow _if_ the gpa+len crosses a page boundary, which thankfully is guaranteed to not happen in the current code base. Add WARNs in more helpers that read/write guest memory to detect similar bugs Selftests: - Fix a goof that caused some Hyper-V tests to be skipped when run on bare metal, i.e. NOT in a VM - Add a regression test for KVM's handling of SHUTDOWN for an SEV-ES guest - Explicitly include one-off assets in .gitignore. Past Sean was completely wrong about not being able to detect missing .gitignore entries - Verify userspace single-stepping works when KVM happens to handle a VM-Exit in its fastpath - Misc cleanups" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (127 commits) Documentation: KVM: fix warning in "make htmldocs" s390: Enable KVM_S390_UCONTROL config in debug_defconfig selftests: kvm: s390: Add VM run test case KVM: SVM: let alternatives handle the cases when RSB filling is required KVM: VMX: Set PFERR_GUEST_{FINAL,PAGE}_MASK if and only if the GVA is valid KVM: x86/mmu: Use KVM_PAGES_PER_HPAGE() instead of an open coded equivalent KVM: x86/mmu: Add KVM_RMAP_MANY to replace open coded '1' and '1ul' literals KVM: x86/mmu: Fold mmu_spte_age() into kvm_rmap_age_gfn_range() KVM: x86/mmu: Morph kvm_handle_gfn_range() into an aging specific helper KVM: x86/mmu: Honor NEED_RESCHED when zapping rmaps and blocking is allowed KVM: x86/mmu: Add a helper to walk and zap rmaps for a memslot KVM: x86/mmu: Plumb a @can_yield parameter into __walk_slot_rmaps() KVM: x86/mmu: Move walk_slot_rmaps() up near for_each_slot_rmap_range() KVM: x86/mmu: WARN on MMIO cache hit when emulating write-protected gfn KVM: x86/mmu: Detect if unprotect will do anything based on invalid_list KVM: x86/mmu: Subsume kvm_mmu_unprotect_page() into the and_retry() version KVM: x86: Rename reexecute_instruction()=>kvm_unprotect_and_retry_on_failure() KVM: x86: Update retry protection fields when forcing retry on emulation failure KVM: x86: Apply retry protection to "unprotect on failure" path KVM: x86: Check EMULTYPE_WRITE_PF_TO_SP before unprotecting gfn ...

The values of the variables xres and yres are placed in strbuf. These variables are obtained from strbuf1. The strbuf1 array contains digit characters and a space if the array contains non-digit characters. Then, when executing sprintf(strbuf, "%ux%ux8", xres, yres); more than 16 bytes will be written to strbuf. It is suggested to increase the size of the strbuf array to 24.

A translated paper describing it is available at https://master.dl.sourceforge.net/project/tomoyo/docs/nsf2003-en.pdf/nsf2003-en.pdf?viasf=1 Although that attempt failed due to mapping problem between inode and pathname, TOMOYO remains as an access restriction tool due to ability to write custom policy by individuals. I was delivering pure LKM version of TOMOYO (named AKARI) to users who cannot afford rebuilding their distro kernels with TOMOYO enabled. But since the LSM framework was converted to static calls, it became more difficult to deliver AKARI to such users. Therefore, I decided to update TOMOYO so that people can use mostly LKM version of TOMOYO with minimal burden for both distributors and users" * tag 'tomoyo-pr-20240927' of git://git.code.sf.net/p/tomoyo/tomoyo: tomoyo: fallback to realpath if symlink's pathname does not exist tomoyo: allow building as a loadable LSM module tomoyo: preparation step for building as a loadable LSM module

Misc cleanups: - Convert devm_cxl_add_root() to return using ERR_CAST() - cxl_test use dev_is_platform() instead of open coding - Remove duplicate include of header core.h in core/cdat.c - use scoped resource management to drop put_device() for cxl_port - Use scoped_guard to drop device_lock() for cxl_port - Refactor __devm_cxl_add_port() to drop gotos - Rename cxl_setup_parent_dport to cxl_dport_init_aer and cxl_dport_map_regs() to cxl_dport_map_ras() - Refactor cxl_dport_init_aer() to be more concise - Remove duplicate host_bridge->native_aer checking in cxl_dport_init_ras_reporting() - Fix comment for cxl_query_cmd()" * tag 'cxl-for-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: (21 commits) cxl: Add documentation to explain the shared link bandwidth calculation cxl: Calculate region bandwidth of targets with shared upstream link cxl: Preserve the CDAT access_coordinate for an endpoint cxl: Fix comment regarding cxl_query_cmd() return data cxl: Convert cxl_internal_send_cmd() to use 'struct cxl_mailbox' as input cxl: Move mailbox related bits to the same context cxl: move cxl headers to new include/cxl/ directory cxl/region: Remove lock from memory notifier callback cxl/pci: simplify the check of mem_enabled in cxl_hdm_decode_init() cxl/pci: Check Mem_info_valid bit for each applicable DVSEC cxl/pci: Remove duplicated implementation of waiting for memory_info_valid cxl/pci: Fix to record only non-zero ranges cxl/pci: Remove duplicate host_bridge->native_aer checking cxl/pci: cxl_dport_map_rch_aer() cleanup cxl/pci: Rename cxl_setup_parent_dport() and cxl_dport_map_regs() cxl/port: Refactor __devm_cxl_add_port() to drop goto pattern cxl/port: Use scoped_guard()/guard() to drop device_lock() for cxl_port cxl/port: Use __free() to drop put_device() for cxl_port cxl: Remove duplicate included header file core.h tools/testing/cxl: Use dev_is_platform() ...
