[PATCH net-next] selftests: mptcp: interpret \n as a new line

by Matthieu Baerts

In case of errors, this message was printed: (...) balanced bwidth with unbalanced delay 5233 max 5005 [ fail ] client exit code 0, server 0 \nnetns ns3-0-EwnkPH socket stat for 10003: (...) Obviously, the idea was to add a new line before the socket stat and not print "\nnetns". The commit 8b974778f998 ("selftests: mptcp: interpret \n as a new line") is very similar to this one. But the modification in simult_flows.sh was missed because this commit above was done in parallel to one here below.

[PATCH v2 00/11] Introduce Simple 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 identified a need for looking closely and investigating atomic_t usages in the kernel when it is used strictly as a counter without 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 to 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. Simple atomic counters api provides interfaces for simple atomic counters that just count, and don't guard resource lifetimes. Counter 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 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. Changes since Patch v1 -- Thanks for reviews and reviewed-by, and Acked-by tags. Updated the patches with the tags. -- Addressed Kees's and Joel's comments: 1. Removed dec_return interfaces (Patch 1/11) 2. Removed counter_simple interfaces to be added later with changes to drivers that use them (if any) (Patch 1/11) 3. Comment and Changelogs updates to Patch 2/11 Kees, if this series is good, would you like to take this through your tree or would you like to take this through mine? Changes since RFC: -- Thanks for reviews and reviewed-by, and Acked-by tags. Updated the patches with the tags. -- Addressed Kees's comments: 1. Non-atomic counters renamed to counter_simple32 and counter_simple64 to clearly indicate size. 2. Added warning for counter_simple* usage and it should be used only when there is no need for atomicity. 3. Renamed counter_atomic to counter_atomic32 to clearly indicate size. 4. Renamed counter_atomic_long to counter_atomic64 and it now uses atomic64_t ops and indicates size. 5. Test updated for the API renames. 6. Added helper functions for test results printing 7. Verified that the test module compiles in kunit env. and test module can be loaded to run the test. 8. Updated Documentation to reflect the intent to make the API restricted so it can never be used to guard object lifetimes and state management. I left _return ops for now, inc_return is necessary for now as per the discussion we had on this topic. -- Updated driver patches with API name changes. -- We discussed if binder counters can be non-atomic. For now I left them the same as the RFC patch - using counter_atomic32 -- Unrelated to this patch series: The patch series review uncovered improvements could be made to test_async_driver_probe and vmw_vmci/vmci_guest. I will track these for fixing later.

[PATCH] selftests/vm: 10x speedup for hmm-tests

by John Hubbard

This patch reduces the running time for hmm-tests from about 10+ seconds, to just under 1.0 second, for an approximately 10x speedup. That brings it in line with most of the other tests in selftests/vm, which mostly run in < 1 sec. This is done with a one-line change that simply reduces the number of iterations of several tests, from 256, to 10. Thanks to Ralph Campbell for suggesting changing NTIMES as a way to get the speedup.

[PATCH bpf-next v4 0/6] bpf: BTF support for ksyms

by Hao Luo

v3 -> v4: - Rebasing - Cast bpf_[per|this]_cpu_ptr's parameter to void __percpu * before passing into per_cpu_ptr. v2 -> v3: - Rename functions and variables in verifier for better readability. - Stick to logging message convention in libbpf. - Move bpf_per_cpu_ptr and bpf_this_cpu_ptr from trace-specific helper set to base helper set. - More specific test in ksyms_btf. - Fix return type cast in bpf_*_cpu_ptr. - Fix btf leak in ksyms_btf selftest. - Fix return error code for kallsyms_find(). v1 -> v2: - Move check_pseudo_btf_id from check_ld_imm() to replace_map_fd_with_map_ptr() and rename the latter. - Add bpf_this_cpu_ptr(). - Use bpf_core_types_are_compat() in libbpf.c for checking type compatibility. - Rewrite typed ksym extern type in BTF with int to save space. - Minor revision of bpf_per_cpu_ptr()'s comments. - Avoid using long in tests that use skeleton. - Refactored test_ksyms.c by moving kallsyms_find() to trace_helpers.c - Fold the patches that sync include/linux/uapi and tools/include/linux/uapi. rfc -> v1: - Encode VAR's btf_id for PSEUDO_BTF_ID. - More checks in verifier. Checking the btf_id passed as PSEUDO_BTF_ID is valid VAR, its name and type. - Checks in libbpf on type compatibility of ksyms. - Add bpf_per_cpu_ptr() to access kernel percpu vars. Introduced new ARG and RET types for this helper. This patch series extends the previously added __ksym externs with btf support. Right now the __ksym externs are treated as pure 64-bit scalar value. Libbpf replaces ld_imm64 insn of __ksym by its kernel address at load time. This patch series extend those externs with their btf info. Note that btf support for __ksym must come with the kernel btf that has VARs encoded to work properly. The corresponding chagnes in pahole is available at [1] (with a fix at [2] for gcc 4.9+). The first 3 patches in this series add support for general kernel global variables, which include verifier checking (01/06), libpf support (02/06) and selftests for getting typed ksym extern's kernel address (03/06). The next 3 patches extends that capability further by introducing helpers bpf_per_cpu_ptr() and bpf_this_cpu_ptr(), which allows accessing kernel percpu variables correctly (04/06 and 05/06). The tests of this feature were performed against pahole that is extended with [1] and [2]. For kernel BTF that does not have VARs encoded, the selftests will be skipped.

It's got Scott's firmware and IMA patches ported and everything tests cleanly for me (even with CONFIG_IMA_APPRAISE=y), and now appears to pass 0day. :) The intention is for this to go via Greg's tree since Scott's driver code will depend on it.

[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 identified a need for looking closely and investigating atomic_t usages in the kernel when it is used strictly as a counter without 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. Changes since RFC: -- Thanks for reviews and reviewed-by, and Acked-by tags. Updated the patches with the tags. -- Addressed Kees's comments: 1. Non-atomic counters renamed to counter_simple32 and counter_simple64 to clearly indicate size. 2. Added warning for counter_simple* usage and it should be used only when there is no need for atomicity. 3. Renamed counter_atomic to counter_atomic32 to clearly indicate size. 4. Renamed counter_atomic_long to counter_atomic64 and it now uses atomic64_t ops and indicates size. 5. Test updated for the API renames. 6. Added helper functions for test results printing 7. Verified that the test module compiles in kunit env. and test module can be loaded to run the test. 8. Updated Documentation to reflect the intent to make the API restricted so it can never be used to guard object lifetimes and state management. I left _return ops for now, inc_return is necessary for now as per the discussion we had on this topic. -- Updated driver patches with API name changes. -- We discussed if binder counters can be non-atomic. For now I left them the same as the RFC patch - using counter_atomic32 -- Unrelated to this patch series: The patch series review uncovered improvements could be made to test_async_driver_probe and vmw_vmci/vmci_guest. I will track these for fixing later.
