[PATCH v1] kunit: tool: fix --alltests flag

by Brendan Higgins

Alltests flag evidently stopped working when run from outside of the root of the source tree, so fix that. Also add an additional broken config to the broken_on_uml config.

While running kselftest ftracetest on i386 the kernel crash reported on linux next tag 5.9.0-rc5-next-20200921.

[PATCH 0/6] kselftest: arm64/mte: Tests for user-space MTE

by Amit Daniel Kachhap

These patch series adds below kselftests to test the user-space support for the ARMv8.5 Memory Tagging Extension present in arm64 tree [1]. 1) This test-case verifies that the memory allocated by kernel mmap interface can support tagged memory access. It first checks the presence of tags at address[56:59] and then proceeds with read and write. The pass criteria for this test is that tag fault exception should not happen. 2) This test-case crosses the valid memory to the invalid memory. In this memory area valid tags are not inserted so read and write should not pass. The pass criteria for this test is that tag fault exception should happen for all the illegal addresses. This test also verfies that PSTATE.TCO works properly. 3) This test-case verifies that the memory inherited by child process from parent process should have same tags copied. The pass criteria for this test is that tag fault exception should not happen. 4) This test checks different mmap flags with PROT_MTE memory protection. 5) This testcase checks that KSM should not merge pages containing different MTE tag values. However, if the tags are same then the pages may merge. This testcase uses the generic ksm sysfs interfaces to verify the MTE behaviour, so this testcase is not fullproof and may be impacted due to other load in the system. 6) Fifth test verifies that syscalls read/write etc works by considering that user pointer has valid/invalid allocation tags. To simplify the testing, a copy of the patchset on top of a recent linux tree can be found at [2].

[RFC PATCH 00/11] Introduce Simple atomic and non-atomic counters

by Shuah Khan

This patch series is a result of discussion at the refcount_t BOF the Linux Plumbers Conference. In this discussion, we identifed a need for looking closely and investigating atomic_t usages in the kernel when it is used strictly as a counter wothout it controlling object lifetimes and state changes. There are a number of atomic_t usages in the kernel where atomic_t api is used strictly for counting and not for managing object lifetime. In some cases, atomic_t might not even be needed. The purpose of these counters is twofold: 1. clearly differentiate atomic_t counters from atomic_t usages that guard object lifetimes, hence prone to overflow and underflow errors. It allows tools that scan for underflow and overflow on atomic_t usages to detect overflow and underflows to scan just the cases that are prone to errors. 2. provides non-atomic counters for cases where atomic isn't necessary. Simple atomic and non-atomic counters api provides interfaces for simple atomic and non-atomic counters that just count, and don't guard resource lifetimes. Counters will wrap around to 0 when it overflows and should not be used to guard resource lifetimes, device usage and open counts that control state changes, and pm states. Using counter_atomic to guard lifetimes could lead to use-after free when it overflows and undefined behavior when used to manage state changes and device usage/open states. This patch series introduces Simple atomic and non-atomic counters. Counter atomic ops leverage atomic_t and provide a sub-set of atomic_t ops. In addition this patch series converts a few drivers to use the new api. The following criteria is used for select variables for conversion: 1. Variable doesn't guard object lifetimes, manage state changes e.g: device usage counts, device open counts, and pm states. 2. Variable is used for stats and counters. 3. The conversion doesn't change the overflow behavior. Please review and let me know if non-stat conversions e.g: probe_count, deferred_trigger_count make sense. Shuah Khan (11): counters: Introduce counter and counter_atomic counters selftests:lib:test_counters: add new test for counters drivers/base: convert deferred_trigger_count and probe_count to counter_atomic drivers/base/devcoredump: convert devcd_count to counter_atomic drivers/acpi: convert seqno counter_atomic drivers/acpi/apei: convert seqno counter_atomic drivers/android/binder: convert stats, transaction_log to counter_atomic drivers/base/test/test_async_driver_probe: convert to use counter_atomic drivers/char/ipmi: convert stats to use counter_atomic drivers/misc/vmw_vmci: convert num guest devices counter to counter_atomic drivers/edac: convert pci counters to counter_atomic Documentation/core-api/counters.rst | 158 +++++++++ MAINTAINERS | 8 + drivers/acpi/acpi_extlog.c | 5 +- drivers/acpi/apei/ghes.c | 5 +- drivers/android/binder.c | 41 +-- drivers/android/binder_internal.h | 3 +- drivers/base/dd.c | 19 +- drivers/base/devcoredump.c | 5 +- drivers/base/test/test_async_driver_probe.c | 23 +- drivers/char/ipmi/ipmi_msghandler.c | 9 +- drivers/char/ipmi/ipmi_si_intf.c | 9 +- drivers/edac/edac_pci.h | 5 +- drivers/edac/edac_pci_sysfs.c | 28 +- drivers/misc/vmw_vmci/vmci_guest.c | 9 +- include/linux/counters.h | 343 +++++++++++++++++++ lib/Kconfig | 10 + lib/Makefile | 1 + lib/test_counters.c | 283 +++++++++++++++ tools/testing/selftests/lib/Makefile | 1 + tools/testing/selftests/lib/config | 1 + tools/testing/selftests/lib/test_counters.sh | 5 + 21 files changed, 897 insertions(+), 74 deletions(-) create mode 100644 Documentation/core-api/counters.rst create mode 100644 include/linux/counters.h create mode 100644 lib/test_counters.c create mode 100755 tools/testing/selftests/lib/test_counters.sh -- 2.25.1

[PATCH v5 bpf-next 0/6] bpf: add helpers to support BTF-based kernel data display

by Alan Maguire

This series attempts to provide a simple way for BPF programs (and in future other consumers) to utilize BPF Type Format (BTF) information to display kernel data structures in-kernel. The use case this functionality is applied to here is to support a snprintf()-like helper to copy a BTF representation of kernel data to a string, and a BPF seq file helper to display BTF data for an iterator. There is already support in kernel/bpf/btf.c for "show" functionality; the changes here generalize that support from seq-file specific verifier display to the more generic case and add another specific use case; rather than seq_printf()ing the show data, it is copied to a supplied string using a snprintf()-like function. Other future consumers of the show functionality could include a bpf_printk_btf() function which printk()ed the data instead. Oops messaging in particular would be an interesting application for such functionality. The above potential use case hints at a potential reply to a reasonable objection that such typed display should be solved by tracing programs, where the in-kernel tracing records data and the userspace program prints it out. While this is certainly the recommended approach for most cases, I believe having an in-kernel mechanism would be valuable also. Critically in BPF programs it greatly simplifies debugging and tracing of such data to invoking a simple helper. One challenge raised in an earlier iteration of this work - where the BTF printing was implemented as a printk() format specifier - was that the amount of data printed per printk() was large, and other format specifiers were far simpler. Here we sidestep that concern by printing components of the BTF representation as we go for the seq file case, and in the string case the snprintf()-like operation is intended to be a basis for perf event or ringbuf output. The reasons for avoiding bpf_trace_printk are that 1. bpf_trace_printk() strings are restricted in size and cannot display anything beyond trivial data structures; and 2. bpf_trace_printk() is for debugging purposes only. As Alexei suggested, a bpf_trace_puts() helper could solve this in the future but it still would be limited by the 1000 byte limit for traced strings. Default output for an sk_buff looks like this (zeroed fields are omitted): (struct sk_buff){ .transport_header = (__u16)65535, .mac_header = (__u16)65535, .end = (sk_buff_data_t)192, .head = (unsigned char *)0x000000007524fd8b, .data = (unsigned char *)0x000000007524fd8b, .truesize = (unsigned int)768, .users = (refcount_t){ .refs = (atomic_t){ .counter = (int)1, }, }, } Flags can modify aspects of output format; see patch 3 for more details. Changes since v4: - Changed approach from a BPF trace event-centric design to one utilizing a snprintf()-like helper and an iter helper (Alexei, patches 3,5) - Added tests to verify BTF output (patch 4) - Added support to tests for verifying BTF type_id-based display as well as type name via __builtin_btf_type_id (Andrii, patch 4). - Augmented task iter tests to cover the BTF-based seq helper. Because a task_struct's BTF-based representation would overflow the PAGE_SIZE limit on iterator data, the "struct fs_struct" (task->fs) is displayed for each task instead (Alexei, patch 6). Changes since v3: - Moved to RFC since the approach is different (and bpf-next is closed) - Rather than using a printk() format specifier as the means of invoking BTF-enabled display, a dedicated BPF helper is used. This solves the issue of printk() having to output large amounts of data using a complex mechanism such as BTF traversal, but still provides a way for the display of such data to be achieved via BPF programs. Future work could include a bpf_printk_btf() function to invoke display via printk() where the elements of a data structure are printk()ed one at a time. Thanks to Petr Mladek, Andy Shevchenko and Rasmus Villemoes who took time to look at the earlier printk() format-specifier-focused version of this and provided feedback clarifying the problems with that approach. - Added trace id to the bpf_trace_printk events as a means of separating output from standard bpf_trace_printk() events, ensuring it can be easily parsed by the reader. - Added bpf_trace_btf() helper tests which do simple verification of the various display options. Changes since v2: - Alexei and Yonghong suggested it would be good to use probe_kernel_read() on to-be-shown data to ensure safety during operation. Safe copy via probe_kernel_read() to a buffer object in "struct btf_show" is used to support this. A few different approaches were explored including dynamic allocation and per-cpu buffers. The downside of dynamic allocation is that it would be done during BPF program execution for bpf_trace_printk()s using %pT format specifiers. The problem with per-cpu buffers is we'd have to manage preemption and since the display of an object occurs over an extended period and in printk context where we'd rather not change preemption status, it seemed tricky to manage buffer safety while considering preemption. The approach of utilizing stack buffer space via the "struct btf_show" seemed like the simplest approach. The stack size of the associated functions which have a "struct btf_show" on their stack to support show operation (btf_type_snprintf_show() and btf_type_seq_show()) stays under 500 bytes. The compromise here is the safe buffer we use is small - 256 bytes - and as a result multiple probe_kernel_read()s are needed for larger objects. Most objects of interest are smaller than this (e.g. "struct sk_buff" is 224 bytes), and while task_struct is a notable exception at ~8K, performance is not the priority for BTF-based display. (Alexei and Yonghong, patch 2). - safe buffer use is the default behaviour (and is mandatory for BPF) but unsafe display - meaning no safe copy is done and we operate on the object itself - is supported via a 'u' option. - pointers are prefixed with 0x for clarity (Alexei, patch 2) - added additional comments and explanations around BTF show code, especially around determining whether objects such zeroed. Also tried to comment safe object scheme used. (Yonghong, patch 2) - added late_initcall() to initialize vmlinux BTF so that it would not have to be initialized during printk operation (Alexei, patch 5) - removed CONFIG_BTF_PRINTF config option as it is not needed; CONFIG_DEBUG_INFO_BTF can be used to gate test behaviour and determining behaviour of type-based printk can be done via retrieval of BTF data; if it's not there BTF was unavailable or broken (Alexei, patches 4,6) - fix bpf_trace_printk test to use vmlinux.h and globals via skeleton infrastructure, removing need for perf events (Andrii, patch 8) Changes since v1: - changed format to be more drgn-like, rendering indented type info along with type names by default (Alexei) - zeroed values are omitted (Arnaldo) by default unless the '0' modifier is specified (Alexei) - added an option to print pointer values without obfuscation. The reason to do this is the sysctls controlling pointer display are likely to be irrelevant in many if not most tracing contexts. Some questions on this in the outstanding questions section below... - reworked printk format specifer so that we no longer rely on format %pT<type> but instead use a struct * which contains type information (Rasmus). This simplifies the printk parsing, makes use more dynamic and also allows specification by BTF id as well as name. - removed incorrect patch which tried to fix dereferencing of resolved BTF info for vmlinux; instead we skip modifiers for the relevant case (array element type determination) (Alexei). - fixed issues with negative snprintf format length (Rasmus) - added test cases for various data structure formats; base types, typedefs, structs, etc. - tests now iterate through all typedef, enum, struct and unions defined for vmlinux BTF and render a version of the target dummy value which is either all zeros or all 0xff values; the idea is this exercises the "skip if zero" and "print everything" cases. - added support in BPF for using the %pT format specifier in bpf_trace_printk() - added BPF tests which ensure %pT format specifier use works (Alexei).

[PATCH 00/15] selftests/seccomp: Refactor change_syscall()

by Kees Cook

Hi, This refactors the seccomp selftest macros used in change_syscall(), in an effort to remove special cases for mips, arm, arm64, and xtensa, which paves the way for powerpc fixes. I'm not entirely done testing, but all-arch build tests and x86_64 selftests pass. I'll be doing arm, arm64, and i386 selftests shortly, but I currently don't have an easy way to check xtensa, mips, nor powerpc. Any help there would be appreciated! (FWIW, I expect to take these via the seccomp tree.) Thanks, -Kees Kees Cook (15): selftests/seccomp: Refactor arch register macros to avoid xtensa special case selftests/seccomp: Provide generic syscall setting macro selftests/seccomp: mips: Define SYSCALL_NUM_SET macro selftests/seccomp: arm: Define SYSCALL_NUM_SET macro selftests/seccomp: arm64: Define SYSCALL_NUM_SET macro selftests/seccomp: mips: Remove O32-specific macro selftests/seccomp: Remove syscall setting #ifdefs selftests/seccomp: Convert HAVE_GETREG into ARCH_GETREG/ARCH_SETREG selftests/seccomp: Convert REGSET calls into ARCH_GETREG/ARCH_SETREG selftests/seccomp: Avoid redundant register flushes selftests/seccomp: Remove SYSCALL_NUM_RET_SHARE_REG in favor of SYSCALL_RET_SET selftests/seccomp: powerpc: Fix seccomp return value testing selftests/seccomp: powerpc: Set syscall return during ptrace syscall exit selftests/clone3: Avoid OS-defined clone_args selftests/seccomp: Use __NR_mknodat instead of __NR_mknod .../selftests/clone3/clone3_selftests.h | 16 +- tools/testing/selftests/seccomp/seccomp_bpf.c | 313 ++++++++++-------- 2 files changed, 184 insertions(+), 145 deletions(-) -- 2.25.1
