[PATCH v18 00/15] arm64: untag user pointers passed to the kernel

by Andrey Konovalov

=== Overview arm64 has a feature called Top Byte Ignore, which allows to embed pointer tags into the top byte of each pointer. Userspace programs (such as HWASan, a memory debugging tool [1]) might use this feature and pass tagged user pointers to the kernel through syscalls or other interfaces. Right now the kernel is already able to handle user faults with tagged pointers, due to these patches: 1. 81cddd65 ("arm64: traps: fix userspace cache maintenance emulation on a tagged pointer") 2. 7dcd9dd8 ("arm64: hw_breakpoint: fix watchpoint matching for tagged pointers") 3. 276e9327 ("arm64: entry: improve data abort handling of tagged pointers") This patchset extends tagged pointer support to syscall arguments. As per the proposed ABI change [3], tagged pointers are only allowed to be passed to syscalls when they point to memory ranges obtained by anonymous mmap() or sbrk() (see the patchset [3] for more details). For non-memory syscalls this is done by untaging user pointers when the kernel performs pointer checking to find out whether the pointer comes from userspace (most notably in access_ok). The untagging is done only when the pointer is being checked, the tag is preserved as the pointer makes its way through the kernel and stays tagged when the kernel dereferences the pointer when perfoming user memory accesses. The mmap and mremap (only new_addr) syscalls do not currently accept tagged addresses. Architectures may interpret the tag as a background colour for the corresponding vma. Other memory syscalls (mprotect, etc.) don't do user memory accesses but rather deal with memory ranges, and untagged pointers are better suited to describe memory ranges internally. Thus for memory syscalls we untag pointers completely when they enter the kernel. === Other approaches One of the alternative approaches to untagging that was considered is to completely strip the pointer tag as the pointer enters the kernel with some kind of a syscall wrapper, but that won't work with the countless number of different ioctl calls. With this approach we would need a custom wrapper for each ioctl variation, which doesn't seem practical. An alternative approach to untagging pointers in memory syscalls prologues is to inspead allow tagged pointers to be passed to find_vma() (and other vma related functions) and untag them there. Unfortunately, a lot of find_vma() callers then compare or subtract the returned vma start and end fields against the pointer that was being searched. Thus this approach would still require changing all find_vma() callers. === Testing The following testing approaches has been taken to find potential issues with user pointer untagging: 1. Static testing (with sparse [2] and separately with a custom static analyzer based on Clang) to track casts of __user pointers to integer types to find places where untagging needs to be done. 2. Static testing with grep to find parts of the kernel that call find_vma() (and other similar functions) or directly compare against vm_start/vm_end fields of vma. 3. Static testing with grep to find parts of the kernel that compare user pointers with TASK_SIZE or other similar consts and macros. 4. Dynamic testing: adding BUG_ON(has_tag(addr)) to find_vma() and running a modified syzkaller version that passes tagged pointers to the kernel. Based on the results of the testing the requried patches have been added to the patchset. === Notes This patchset is meant to be merged together with "arm64 relaxed ABI" [3]. This patchset is a prerequisite for ARM's memory tagging hardware feature support [4]. This patchset has been merged into the Pixel 2 & 3 kernel trees and is now being used to enable testing of Pixel phones with HWASan. Thanks!

There is some minor clean-up as well". Changes in v17: - The "uaccess: add noop untagged_addr definition" patch is dropped, as it was merged into upstream named as "uaccess: add noop untagged_addr definition". - Merged "mm, arm64: untag user pointers in do_pages_move" into "mm, arm64: untag user pointers passed to memory syscalls". - Added "arm64: Introduce prctl() options to control the tagged user addresses ABI" patch from Catalin. - Add tags_lib.so to tools/testing/selftests/arm64/.gitignore. - Added a comment clarifying untagged in mremap. - Moved untagging back into mlx4_get_umem_mr() for the IB patch. Changes in v16: - Moved untagging for memory syscalls from arm64 wrappers back to generic code. - Dropped untagging for the following memory syscalls: brk, mmap, munmap; mremap (only dropped for new_address); mmap_pgoff (not used on arm64); remap_file_pages (deprecated); shmat, shmdt (work on shared memory). - Changed kselftest to LD_PRELOAD a shared library that overrides malloc to return tagged pointers. - Rebased onto 5.2-rc3. Changes in v15: - Removed unnecessary untagging from radeon_ttm_tt_set_userptr(). - Removed unnecessary untagging from amdgpu_ttm_tt_set_userptr(). - Moved untagging to validate_range() in userfaultfd code. - Moved untagging to ib_uverbs_(re)reg_mr() from mlx4_get_umem_mr(). - Rebased onto 5.1. Changes in v14: - Moved untagging for most memory syscalls to an arm64 specific implementation, instead of doing that in the common code. - Dropped "net, arm64: untag user pointers in tcp_zerocopy_receive", since the provided user pointers don't come from an anonymous map and thus are not covered by this ABI relaxation. - Dropped "kernel, arm64: untag user pointers in prctl_set_mm*". - Moved untagging from __check_mem_type() to tee_shm_register(). - Updated untagging for the amdgpu and radeon drivers to cover the MMU notifier, as suggested by Felix. - Since this ABI relaxation doesn't actually allow tagged instruction pointers, dropped the following patches: - Dropped "tracing, arm64: untag user pointers in seq_print_user_ip". - Dropped "uprobes, arm64: untag user pointers in find_active_uprobe". - Dropped "bpf, arm64: untag user pointers in stack_map_get_build_id_offset". - Rebased onto 5.1-rc7 (37624b58). Changes in v13: - Simplified untagging in tcp_zerocopy_receive(). - Looked at find_vma() callers in drivers/, which allowed to identify a few other places where untagging is needed. - Added patch "mm, arm64: untag user pointers in get_vaddr_frames". - Added patch "drm/amdgpu, arm64: untag user pointers in amdgpu_ttm_tt_get_user_pages". - Added patch "drm/radeon, arm64: untag user pointers in radeon_ttm_tt_pin_userptr". - Added patch "IB/mlx4, arm64: untag user pointers in mlx4_get_umem_mr". - Added patch "media/v4l2-core, arm64: untag user pointers in videobuf_dma_contig_user_get". - Added patch "tee/optee, arm64: untag user pointers in check_mem_type". - Added patch "vfio/type1, arm64: untag user pointers". Changes in v12: - Changed untagging in tcp_zerocopy_receive() to also untag zc->address. - Fixed untagging in prctl_set_mm* to only untag pointers for vma lookups and validity checks, but leave them as is for actual user space accesses. - Updated the link to the v2 of the "arm64 relaxed ABI" patchset [3]. - Dropped the documentation patch, as the "arm64 relaxed ABI" patchset [3] handles that. Changes in v11: - Added "uprobes, arm64: untag user pointers in find_active_uprobe" patch. - Added "bpf, arm64: untag user pointers in stack_map_get_build_id_offset" patch. - Fixed "tracing, arm64: untag user pointers in seq_print_user_ip" to correctly perform subtration with a tagged addr. - Moved untagged_addr() from SYSCALL_DEFINE3(mprotect) and SYSCALL_DEFINE4(pkey_mprotect) to do_mprotect_pkey(). - Moved untagged_addr() definition for other arches from include/linux/memory.h to include/linux/mm.h. - Changed untagging in strn*_user() to perform userspace accesses through tagged pointers. - Updated the documentation to mention that passing tagged pointers to memory syscalls is allowed. - Updated the test to use malloc'ed memory instead of stack memory. Changes in v10: - Added "mm, arm64: untag user pointers passed to memory syscalls" back. - New patch "fs, arm64: untag user pointers in fs/userfaultfd.c". - New patch "net, arm64: untag user pointers in tcp_zerocopy_receive". - New patch "kernel, arm64: untag user pointers in prctl_set_mm*". - New patch "tracing, arm64: untag user pointers in seq_print_user_ip". Changes in v9: - Rebased onto 4.20-rc6. - Used u64 instead of __u64 in type casts in the untagged_addr macro for arm64. - Added braces around (addr) in the untagged_addr macro for other arches. Changes in v8: - Rebased onto 65102238 (4.20-rc1). - Added a note to the cover letter on why syscall wrappers/shims that untag user pointers won't work. - Added a note to the cover letter that this patchset has been merged into the Pixel 2 kernel tree. - Documentation fixes, in particular added a list of syscalls that don't support tagged user pointers. Changes in v7: - Rebased onto 17b57b18 (4.19-rc6). - Dropped the "arm64: untag user address in __do_user_fault" patch, since the existing patches already handle user faults properly. - Dropped the "usb, arm64: untag user addresses in devio" patch, since the passed pointer must come from a vma and therefore be untagged. - Dropped the "arm64: annotate user pointers casts detected by sparse" patch (see the discussion to the replies of the v6 of this patchset). - Added more context to the cover letter. - Updated Documentation/arm64/tagged-pointers.txt.

Changes in v2: - Rebased onto 2d618bdf (4.17-rc3+). - Removed excessive untagging in gup.c. - Removed untagging pointers returned from __uaccess_mask_ptr. Changes in v1: - Rebased onto 4.17-rc1. Changes in RFC v2: - Added "#ifndef untagged_addr..." fallback in linux/uaccess.h instead of defining it for each arch individually. - Updated Documentation/arm64/tagged-pointers.txt. - Dropped "mm, arm64: untag user addresses in memory syscalls". - Rebased onto 3eb2ce82 (4.16-rc7).

[PATCH AUTOSEL 4.19 13/52] selftests/bpf: fix "bind{4, 6} deny specific IP & port" on s390

by Sasha Levin

[PATCH v3 00/11] Add arm64/signal initial kselftest support

by Cristian Marussi

Hi this patchset aims to add the initial arch-specific arm64 support to kselftest starting with signals-related test-cases. A common internal test-case layout is proposed which then it is anyway wired-up to the toplevel kselftest Makefile, so that it should be possible at the end to run it on an arm64 target in the usual way with KSFT. ~/linux# make TARGETS=arm64 kselftest New KSFT arm64 testcases live inside tools/testing/selftests/arm64 grouped by family inside subdirectories: arm64/signal is the first family proposed with this series. arm64/signal tests can be run via KSFT or standalone. Thanks Cristian Notes: ----- - further details in the included READMEs - more tests still to be written (current strategy is going through the related Kernel signal-handling code and write a test for each possible and sensible code-path) A few ideas in testcases/TODO.readme - a bit of overlap around KSFT arm64/ Makefiles is expected with this: https://lore.kernel.org/linux-arm-kernel/c1e6aad230658bc175b42d92daeff2e300… Changes: -------- v2-->v3: - rebased on v5.3-rc2 - better test result characterization looking for SEGV_ACCERR in si_code on SIGSEGV - using KSFT Framework macros for retvalues - removed SAFE_WRITE()/dump_uc: buggy, un-needed and unused - reviewed generation process of test_arm64_signals.sh runner script - re-added a fixed fake_sigreturn_misaligned_sp testcase and a properly extended fake_sigreturn() helper - added tests' TODO notes v1-->v2: - rebased on 5.2-rc7 - various makefile's cleanups - mixed READMEs fixes - fixed test_arm64_signals.sh runner script - cleaned up assembly code in signal.S - improved get_current_context() logic - fixed SAFE_WRITE() - common support code splitted into more chunks, each one introduced when needed by some new testcases - fixed some headers validation routines in testcases.c - removed some still broken/immature tests: + fake_sigreturn_misaligned + fake_sigreturn_overflow_reserved + mangle_pc_invalid + mangle_sp_misaligned -

[PATCH v4] kunit: fix failure to build without printk

by Brendan Higgins

Previously KUnit assumed that printk would always be present, which is not a valid assumption to make. Fix that by removing call to vprintk_emit, and calling printk directly. This fixes a build error[1] reported by Randy. For context this change comes after much discussion. My first stab[2] at this was just to make the KUnit logging code compile out; however, it was agreed that if we were going to use vprintk_emit, then vprintk_emit should provide a no-op stub, which lead to my second attempt[3]. In response to me trying to stub out vprintk_emit, Sergey Senozhatsky suggested a way for me to remove our usage of vprintk_emit, which led to my third attempt at solving this[4]. In my third version of this patch[4], I completely removed vprintk_emit, as suggested by Sergey; however, there was a bit of debate over whether Sergey's solution was the best. The debate arose due to Sergey's version resulting in a checkpatch warning, which resulted in a debate over correct printk usage. Joe Perches offered an alternative fix which was somewhat less far reaching than what Sergey had suggested and importantly relied on continuing to use %pV. Much of the debated centered around whether %pV should be widely used, and whether Sergey's version would result in object size bloat. Ultimately, we decided to go with Sergey's version.

Changes Since v3: Renamed kunit_print_level to kunit_printk, and changed the KERN_LEVEL macro parameter (in kunit_printk) to lvl, as suggested by Joe. --- include/kunit/test.h | 5 ++-- kunit/test.c | 57 +++++--------------------------------------- 2 files changed, 8 insertions(+), 54 deletions(-) diff --git a/include/kunit/test.h b/include/kunit/test.h index 8b7eb03d4971..dba48304b3bd 100644 --- a/include/kunit/test.h +++ b/include/kunit/test.h @@ -339,9 +339,8 @@ static inline void *kunit_kzalloc(struct kunit *test, size_t size, gfp_t gfp) void kunit_cleanup(struct kunit *test); -void __printf(3, 4) kunit_printk(const char *level, - const struct kunit *test, - const char *fmt, ...); +#define kunit_printk(lvl, test, fmt, ...) \ + printk(lvl "\t# %s: " fmt, (test)->name, ##__VA_ARGS__) /** * kunit_info() - Prints an INFO level message associated with @test. diff --git a/kunit/test.c b/kunit/test.c index b2ca9b94c353..c83c0fa59cbd 100644 --- a/kunit/test.c +++ b/kunit/test.c @@ -16,36 +16,12 @@ static void kunit_set_failure(struct kunit *test) WRITE_ONCE(test->success, false); } -static int kunit_vprintk_emit(int level, const char *fmt, va_list args) -{ - return vprintk_emit(0, level, NULL, 0, fmt, args); -} - -static int kunit_printk_emit(int level, const char *fmt, ...) -{ - va_list args; - int ret; - - va_start(args, fmt); - ret = kunit_vprintk_emit(level, fmt, args); - va_end(args); - - return ret; -} - -static void kunit_vprintk(const struct kunit *test, - const char *level, - struct va_format *vaf) -{ - kunit_printk_emit(level[1] - '0', "\t# %s: %pV", test->name, vaf); -} - static void kunit_print_tap_version(void) { static bool kunit_has_printed_tap_version; if (!kunit_has_printed_tap_version) { - kunit_printk_emit(LOGLEVEL_INFO, "TAP version 14\n"); + pr_info("TAP version 14\n"); kunit_has_printed_tap_version = true; } } @@ -64,10 +40,8 @@ static size_t kunit_test_cases_len(struct kunit_case *test_cases) static void kunit_print_subtest_start(struct kunit_suite *suite) { kunit_print_tap_version(); - kunit_printk_emit(LOGLEVEL_INFO, "\t# Subtest: %s\n", suite->name); - kunit_printk_emit(LOGLEVEL_INFO, - "\t1..%zd\n", - kunit_test_cases_len(suite->test_cases)); + pr_info("\t# Subtest: %s\n", suite->name); + pr_info("\t1..%zd\n", kunit_test_cases_len(suite->test_cases)); } static void kunit_print_ok_not_ok(bool should_indent, @@ -87,9 +61,7 @@ static void kunit_print_ok_not_ok(bool should_indent, else ok_not_ok = "not ok"; - kunit_printk_emit(LOGLEVEL_INFO, - "%s%s %zd - %s\n", - indent, ok_not_ok, test_number, description); + pr_info("%s%s %zd - %s\n", indent, ok_not_ok, test_number, description); } static bool kunit_suite_has_succeeded(struct kunit_suite *suite) @@ -133,11 +105,11 @@ static void kunit_print_string_stream(struct kunit *test, kunit_err(test, "Could not allocate buffer, dumping stream:\n"); list_for_each_entry(fragment, &stream->fragments, node) { - kunit_err(test, fragment->fragment); + kunit_err(test, "%s", fragment->fragment); } kunit_err(test, "\n"); } else { - kunit_err(test, buf); + kunit_err(test, "%s", buf); kunit_kfree(test, buf); } } @@ -504,20 +476,3 @@ void kunit_cleanup(struct kunit *test) kunit_resource_free(test, resource); } } - -void kunit_printk(const char *level, - const struct kunit *test, - const char *fmt, ...) -{ - struct va_format vaf; - va_list args; - - va_start(args, fmt); - - vaf.fmt = fmt; - vaf.va = &args; - - kunit_vprintk(test, level, &vaf); - - va_end(args); -} -- 2.23.0.187.g17f5b7556c-goog
