Changes for v5: * Actually include the revamp for TARGET_TAGGED_ADDRESSES, which got lost at some point before posting v4. Patches lacking review are only the new ones: 0011-exec-Introduce-cpu_untagged_addr.patch 0012-exec-Use-cpu_untagged_addr-in-g2h-split-out-g2h_u.patch 0013-linux-user-Explicitly-untag-memory-management-sys.patch 0014-linux-user-Use-guest_range_valid-in-access_ok.patch 0015-exec-Rename-guest_-addr-range-_valid-to-_untagged.patch 0016-linux-user-Use-cpu_untagged_addr-in-access_ok-spl.patch 0017-linux-user-Move-lock_user-et-al-out-of-line.patch 0018-linux-user-Fix-types-in-uaccess.c.patch 0019-linux-user-Handle-tags-in-lock_user-unlock_user.patch Changes for v4: * Revamp "Add support for TARGET_TAGGED_ADDRESSES". There are now two sets of functions in include/exec/, one for tagged and one for untagged addresses. The former takes a CPUState, and does not assume current_cpu is a thing. So much for the generic bits... However, use of current_cpu remains, pushed down to lock_user. Changing everything that touches that, or get/put_user, is daunting. * Fix tbi0 vs tbi1 for linux-user. This had a number of cascading effects. * Adjust when async errors are noticed. Changes for v3: * Split out type changes to separate patches. * Add doc comments; tweak alloc so that the !PAGE_VALID case is clear. * Do not overlap PAGE_TARGET_2 with PAGE_RESERVED. * Use syndrome.h, arm_deliver_fault. r~ Richard Henderson (31): tcg: Introduce target-specific page data for user-only linux-user: Introduce PAGE_ANON exec: Use uintptr_t for guest_base exec: Use uintptr_t in cpu_ldst.h exec: Improve types for guest_addr_valid linux-user: Check for overflow in access_ok linux-user: Tidy VERIFY_READ/VERIFY_WRITE bsd-user: Tidy VERIFY_READ/VERIFY_WRITE linux-user: Do not use guest_addr_valid for h2g_valid linux-user: Fix guest_addr_valid vs reserved_va exec: Introduce cpu_untagged_addr exec: Use cpu_untagged_addr in g2h; split out g2h_untagged linux-user: Explicitly untag memory management syscalls linux-user: Use guest_range_valid in access_ok exec: Rename guest_{addr,range}_valid to *_untagged linux-user: Use cpu_untagged_addr in access_ok; split out *_untagged linux-user: Move lock_user et al out of line linux-user: Fix types in uaccess.c linux-user: Handle tags in lock_user/unlock_user linux-user/aarch64: Implement PR_TAGGED_ADDR_ENABLE target/arm: Improve gen_top_byte_ignore target/arm: Use the proper TBI settings for linux-user linux-user/aarch64: Implement PR_MTE_TCF and PR_MTE_TAG linux-user/aarch64: Implement PROT_MTE target/arm: Split out syndrome.h from internals.h linux-user/aarch64: Pass syndrome to EXC_*_ABORT linux-user/aarch64: Signal SEGV_MTESERR for sync tag check fault linux-user/aarch64: Signal SEGV_MTEAERR for async tag check error target/arm: Add allocation tag storage for user mode target/arm: Enable MTE for user-only tests/tcg/aarch64: Add mte smoke tests bsd-user/qemu.h | 9 +- include/exec/cpu-all.h | 47 ++++- include/exec/cpu_ldst.h | 39 ++-- include/exec/exec-all.h | 2 +- linux-user/aarch64/target_signal.h | 3 + linux-user/aarch64/target_syscall.h | 13 ++ linux-user/qemu.h | 76 +++----- linux-user/syscall_defs.h | 1 + target/arm/cpu-param.h | 3 + target/arm/cpu.h | 32 ++++ target/arm/internals.h | 249 +------------------------ target/arm/syndrome.h | 273 ++++++++++++++++++++++++++++ tests/tcg/aarch64/mte.h | 60 ++++++ accel/tcg/translate-all.c | 32 +++- accel/tcg/user-exec.c | 57 +++--- bsd-user/main.c | 4 +- linux-user/aarch64/cpu_loop.c | 38 +++- linux-user/elfload.c | 18 +- linux-user/flatload.c | 2 +- linux-user/hppa/cpu_loop.c | 39 ++-- linux-user/i386/cpu_loop.c | 6 +- linux-user/i386/signal.c | 5 +- linux-user/main.c | 4 +- linux-user/mmap.c | 86 +++++---- linux-user/ppc/signal.c | 4 +- linux-user/syscall.c | 165 +++++++++++++---- linux-user/uaccess.c | 82 +++++++-- target/arm/cpu.c | 25 ++- target/arm/helper-a64.c | 4 +- target/arm/mte_helper.c | 39 +++- target/arm/tlb_helper.c | 15 +- target/arm/translate-a64.c | 25 +-- target/hppa/op_helper.c | 2 +- target/i386/tcg/mem_helper.c | 2 +- target/s390x/mem_helper.c | 4 +- tests/tcg/aarch64/mte-1.c | 28 +++ tests/tcg/aarch64/mte-2.c | 45 +++++ tests/tcg/aarch64/mte-3.c | 51 ++++++ tests/tcg/aarch64/mte-4.c | 45 +++++ tests/tcg/aarch64/pauth-2.c | 1 - tests/tcg/aarch64/Makefile.target | 6 + tests/tcg/configure.sh | 4 + 42 files changed, 1126 insertions(+), 519 deletions(-) create mode 100644 target/arm/syndrome.h create mode 100644 tests/tcg/aarch64/mte.h create mode 100644 tests/tcg/aarch64/mte-1.c create mode 100644 tests/tcg/aarch64/mte-2.c create mode 100644 tests/tcg/aarch64/mte-3.c create mode 100644 tests/tcg/aarch64/mte-4.c
