[PATCH v1] kobject: make sure parent is not released before children

by Brendan Higgins

From: Heikki Krogerus <heikki.krogerus(a)linux.intel.com> Previously, kobjects were released before the associated kobj_types; this can cause a kobject deallocation to fail when the kobject has children; an example of this is in software_node_unregister_nodes(); it calls release on the parent before children meaning that children can be released after the parent, which may be needed for removal. So, take a reference to the parent before we delete a node to ensure that the parent is not released before the children. Reported-by: Naresh Kamboju <naresh.kamboju(a)linaro.org> Fixes: 7589238a8cf3 ("Revert "software node: Simplify software_node_release() function"") Link: https://lore.kernel.org/linux-kselftest/CAFd5g44s5NQvT8TG_x4rwbqoa7zWzkV0TX… Co-developed-by: Brendan Higgins <brendanhiggins(a)google.com> Signed-off-by: Brendan Higgins <brendanhiggins(a)google.com> --- This patch is based on the diff written by Heikki linked above.

[PATCH v9 0/3] mm/hmm/test: add self tests for HMM

by Ralph Campbell

This series adds basic self tests for HMM and are intended for Jason Gunthorpe's rdma tree since I believe he is planning to make some HMM related changes that this can help test. Changes v8 -> v9: Rebased to linux-5.7.0-rc1. Moved include/uapi/linux/test_hmm.h to lib/test_hmm_uapi.h Added calls to release_mem_region() to free device private addresses Applied Jason's suggested changes for v8. Added a check for no VMA read access before migrating to device private memory. Changes v7 -> v8: Rebased to Jason's rdma/hmm tree, plus Jason's 6 patch series "Small hmm_range_fault() cleanups". Applied a number of changes from Jason's comments. Changes v6 -> v7: Rebased to linux-5.6.0-rc6 Reverted back to just using mmu_interval_notifier_insert() and making this series only introduce HMM self tests. Changes v5 -> v6: Rebased to linux-5.5.0-rc6 Refactored mmu interval notifier patches Converted nouveau to use the new mmu interval notifier API Changes v4 -> v5: Added mmu interval notifier insert/remove/update callable from the invalidate() callback Updated HMM tests to use the new core interval notifier API Changes v1 -> v4: https://lore.kernel.org/linux-mm/20191104222141.5173-1-rcampbell@nvidia.com Ralph Campbell (3): mm/hmm/test: add selftest driver for HMM mm/hmm/test: add selftests for HMM MAINTAINERS: add HMM selftests MAINTAINERS | 3 + lib/Kconfig.debug | 13 + lib/Makefile | 1 + lib/test_hmm.c | 1175 ++++++++++++++++++++ lib/test_hmm_uapi.h | 59 + tools/testing/selftests/vm/.gitignore | 1 + tools/testing/selftests/vm/Makefile | 3 + tools/testing/selftests/vm/config | 2 + tools/testing/selftests/vm/hmm-tests.c | 1359 ++++++++++++++++++++++++ tools/testing/selftests/vm/run_vmtests | 16 + tools/testing/selftests/vm/test_hmm.sh | 97 ++ 11 files changed, 2729 insertions(+) create mode 100644 lib/test_hmm.c create mode 100644 lib/test_hmm_uapi.h create mode 100644 tools/testing/selftests/vm/hmm-tests.c create mode 100755 tools/testing/selftests/vm/test_hmm.sh -- 2.25.2

[PATCH v3] selftests/harness: Add support for argc and argv.

by Kuniyuki Iwashima

Currently tests are often written in C and shell script. In many cases, the script passes some arguments to the C program. However, the helper functions do not support arguments, so many tests are written without helper functions. This patch introduces two function macros: ARG_SETUP and ARG_TEARDOWN. The 'argc' and 'argv' are exposed as the member of the 'arg'. We can parse them and populate/cleanup the 'arg->data' in ARG_SETUP/ARG_TEARDOWN. The 'arg' is passed to TEST, TEST_*, and FIXTURE_* so that we can write tests more flexibly with helper functions.

[PATCH v3 0/7] firmware: add partial read support in request_firmware_into_buf

by Scott Branden

This patch series adds partial read support in request_firmware_into_buf. In order to accept the enhanced API it has been requested that kernel selftests and upstreamed driver utilize the API enhancement and so are included in this patch series. Also in this patch series is the addition of a new Broadcom VK driver utilizing the new request_firmware_into_buf enhanced API. Changes from v2: - remove unnecessary code and mutex locks in lib/test_firmware.c - remove VK_IOCTL_ACCESS_BAR support from driver and use pci sysfs instead - remove bitfields - remove Kconfig default m - adjust formatting and some naming based on feedback - fix error handling conditions - use appropriate return codes - use memcpy_toio instead of direct access to PCIE bar - Scott Branden (7): fs: introduce kernel_pread_file* support firmware: add offset to request_firmware_into_buf test_firmware: add partial read support for request_firmware_into_buf firmware: test partial file reads of request_firmware_into_buf bcm-vk: add bcm_vk UAPI misc: bcm-vk: add Broadcom VK driver MAINTAINERS: bcm-vk: add maintainer for Broadcom VK Driver MAINTAINERS | 7 + drivers/base/firmware_loader/firmware.h | 5 + drivers/base/firmware_loader/main.c | 52 +- drivers/misc/Kconfig | 1 + drivers/misc/Makefile | 1 + drivers/misc/bcm-vk/Kconfig | 41 + drivers/misc/bcm-vk/Makefile | 12 + drivers/misc/bcm-vk/bcm_vk.h | 406 +++++ drivers/misc/bcm-vk/bcm_vk_dev.c | 1179 ++++++++++++++ drivers/misc/bcm-vk/bcm_vk_legacy.c | 89 ++ drivers/misc/bcm-vk/bcm_vk_msg.c | 1420 +++++++++++++++++ drivers/misc/bcm-vk/bcm_vk_msg.h | 215 +++ drivers/misc/bcm-vk/bcm_vk_sg.c | 271 ++++ drivers/misc/bcm-vk/bcm_vk_sg.h | 60 + drivers/misc/bcm-vk/bcm_vk_tty.c | 323 ++++ drivers/soc/qcom/mdt_loader.c | 7 +- fs/exec.c | 96 +- include/linux/firmware.h | 8 +- include/linux/fs.h | 20 + include/uapi/linux/misc/bcm_vk.h | 99 ++ lib/test_firmware.c | 144 +- .../selftests/firmware/fw_filesystem.sh | 80 + 22 files changed, 4487 insertions(+), 49 deletions(-) create mode 100644 drivers/misc/bcm-vk/Kconfig create mode 100644 drivers/misc/bcm-vk/Makefile create mode 100644 drivers/misc/bcm-vk/bcm_vk.h create mode 100644 drivers/misc/bcm-vk/bcm_vk_dev.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_legacy.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_msg.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_msg.h create mode 100644 drivers/misc/bcm-vk/bcm_vk_sg.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_sg.h create mode 100644 drivers/misc/bcm-vk/bcm_vk_tty.c create mode 100644 include/uapi/linux/misc/bcm_vk.h -- 2.17.1

' # %s: Unknown error: %d lib/kunit/try-catch.c 58 void kunit_try_catch_run(struct kunit_try_catch *try_catch, void *context) 59 { 60 DECLARE_COMPLETION_ONSTACK(try_completion); 61 struct kunit *test = try_catch->test; 62 struct task_struct *task_struct; 63 int exit_code, time_remaining; 64 65 try_catch->context = context; 66 try_catch->try_completion = &try_completion; 67 try_catch->try_result = 0; 68 task_struct = kthread_run(kunit_generic_run_threadfn_adapter, 69 try_catch, 70 "kunit_try_catch_thread"); 71 if (IS_ERR(task_struct)) { 72 try_catch->catch(try_catch->context); 73 return; 74 } 75 76 time_remaining = wait_for_completion_timeout(&try_completion, 77 kunit_test_timeout()); 78 if (time_remaining == 0) { 79 kunit_err(test, "try timed out\n"); ^^ The kunit_log() macro adds its own newline. Most of the callers add a newline. It should be the callers add a newline because that's how everything else works in the kernel. The dev_printk() stuff will sometimes add a newline, but never a duplicate newline. In other words, it's slightly complicated. But basically the caller should add a newline. 80 try_catch->try_result = -ETIMEDOUT; 81 } 82 83 exit_code = try_catch->try_result; 84 85 if (!exit_code) 86 return; 87 88 if (exit_code == -EFAULT) 89 try_catch->try_result = 0; 90 else if (exit_code == -EINTR) 91 kunit_err(test, "wake_up_process() was never called\n"); ^^ 92 else if (exit_code) 93 kunit_err(test, "Unknown error: %d\n", exit_code); ^^ 94 95 try_catch->catch(try_catch->context); 96 } regards, dan carpenter
