Pull audit updates from Paul Moore: "We've got a reasonably broad set of audit patches for the v5.2 merge window, the highlights are below: - The biggest change, and the source of all the arch/* changes, is the patchset from Dmitry to help enable some of the work he is doing around PTRACE_GET_SYSCALL_INFO. To be honest, including this in the audit tree is a bit of a stretch, but it does help move audit a little further along towards proper syscall auditing for all arches, and everyone else seemed to agree that audit was a "good" spot for this to land (or maybe they just didn't want to merge it? dunno.). - We can now audit time/NTP adjustments. - We continue the work to connect associated audit records into a single event" * tag 'audit-pr-20190507' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit: (21 commits) audit: fix a memory leak bug ntp: Audit NTP parameters adjustment timekeeping: Audit clock adjustments audit: purge unnecessary list_empty calls audit: link integrity evm_write_xattrs record to syscall event syscall_get_arch: add "struct task_struct *" argument unicore32: define syscall_get_arch() Move EM_UNICORE to uapi/linux/elf-em.h nios2: define syscall_get_arch() nds32: define syscall_get_arch() Move EM_NDS32 to uapi/linux/elf-em.h m68k: define syscall_get_arch() hexagon: define syscall_get_arch() Move EM_HEXAGON to uapi/linux/elf-em.h h8300: define syscall_get_arch() c6x: define syscall_get_arch() arc: define syscall_get_arch() Move EM_ARCOMPACT and EM_ARCV2 to uapi/linux/elf-em.h audit: Make audit_log_cap and audit_copy_inode static audit: connect LOGIN record to its syscall record ...

arch/tlb: Clean up simple architectures

2019-04-03T08:32:54Z

For the architectures that do not implement their own tlb_flush() but do already use the generic mmu_gather, there are two options: 1) the platform has an efficient flush_tlb_range() and asm-generic/tlb.h doesn't need any overrides at all. 2) the platform lacks an efficient flush_tlb_range() and we select MMU_GATHER_NO_RANGE to minimize full invalidates. Convert all 'simple' architectures to one of these two forms. alpha: has no range invalidate -> 2 arc: already used flush_tlb_range() -> 1 c6x: has no range invalidate -> 2 hexagon: has an efficient flush_tlb_range() -> 1 (flush_tlb_mm() is in fact a full range invalidate, so no need to shoot down everything) m68k: has inefficient flush_tlb_range() -> 2 microblaze: has no flush_tlb_range() -> 2 mips: has efficient flush_tlb_range() -> 1 (even though it currently seems to use flush_tlb_mm()) nds32: already uses flush_tlb_range() -> 1 nios2: has inefficient flush_tlb_range() -> 2 (no limit on range iteration) openrisc: has inefficient flush_tlb_range() -> 2 (no limit on range iteration) parisc: already uses flush_tlb_range() -> 1 sparc32: already uses flush_tlb_range() -> 1 unicore32: has inefficient flush_tlb_range() -> 2 (no limit on range iteration) xtensa: has efficient flush_tlb_range() -> 1 Note this also fixes a bug in the existing code for a number platforms. Those platforms that did: tlb_end_vma() -> if (!full_mm) flush_tlb_*() tlb_flush -> if (full_mm) flush_tlb_mm() missed the case of shift_arg_pages(), which doesn't have @fullmm set, nor calls into tlb_*vma(), but still frees page-tables and thus needs an invalidate. The new code handles this by detecting a non-empty range, and either issuing the matching range invalidate or a full invalidate, depending on the capabilities. No change in behavior intended.

KVM: export and iif KVM is supported

2019-03-28T16:27:42Z

I do not see any consistency about headers_install of and . According to my analysis of Linux 5.1-rc1, there are 3 groups: [1] Both and are exported alpha, arm, hexagon, mips, powerpc, s390, sparc, x86 [2] is exported, but is not arc, arm64, c6x, h8300, ia64, m68k, microblaze, nios2, openrisc, parisc, sh, unicore32, xtensa [3] Neither nor is exported csky, nds32, riscv This does not match to the actual KVM support. At least, [2] is half-baked. Nor do arch maintainers look like they care about this. For example, commit 0add53713b1c ("microblaze: Add missing kvm_para.h to Kbuild") exported to user-space in order to fix an in-kernel build error. We have two ways to make this consistent: [A] export both and for all architectures, irrespective of the KVM support [B] Match the header export of and to the KVM support My first attempt was [A] because the code looks cleaner, but Paolo suggested [B]. So, this commit goes with [B]. For most architectures, was moved to the kernel-space. I changed include/uapi/linux/Kbuild so that it checks generated asm/kvm_para.h as well as check-in ones. After this commit, there will be two groups: [1] Both and are exported arm, arm64, mips, powerpc, s390, x86 [2] Neither nor is exported alpha, arc, c6x, csky, h8300, hexagon, ia64, m68k, microblaze, nds32, nios2, openrisc, parisc, riscv, sh, sparc, unicore32, xtensa Signed-off-by: Masahiro Yamada Acked-by: Cornelia Huck Signed-off-by: Paolo Bonzini
