[RFC 0/7] selftests: kselftest_harness: use common result printing helper

by Jakub Kicinski

Add a common result printing helper and always include test name in the result line. Previously when SKIP or XPASS would happen we printed: ok 1 # SKIP unknown without the test name. Now we'll print: ok 1 global.no_pad # SKIP unknown This appears to be more inline with: https://docs.kernel.org/dev-tools/ktap.html and makes parsing results easier. First 3 patches rearrange kselftest_harness to use exit code as an enum rather than separate passed/skip/xfail members. Rest of the series builds a ksft_test_result_code() helper.

[PATCH net-next v2 0/4] selftests: kselftest_harness: support using xfail

by Jakub Kicinski

Hi! When running selftests for our subsystem in our CI we'd like all tests to pass. Currently some tests use SKIP for cases they expect to fail, because the kselftest_harness limits the return codes to pass/fail/skip. Clean up and support the use of the full range of ksft exit codes under kselftest_harness. Merge plan is to put it on top of -rc4 and merge into net-next. That way others should be able to pull the patches without any networking changes. v2: - fix alignment v1: https://lore.kernel.org/all/20240213154416.422739-1-kuba@kernel.org/ Jakub Kicinski (4): selftests: kselftest_harness: pass step via shared memory selftests: kselftest_harness: use KSFT_* exit codes selftests: kselftest_harness: support using xfail selftests: ip_local_port_range: use XFAIL instead of SKIP tools/testing/selftests/kselftest_harness.h | 67 ++++++++++++++----- .../selftests/net/ip_local_port_range.c | 2 +- 2 files changed, 52 insertions(+), 17 deletions(-) -- 2.43.0

[PATCH v10 00/25] security: Move IMA and EVM to the LSM infrastructure

by Roberto Sassu

From: Roberto Sassu <roberto.sassu(a)huawei.com> IMA and EVM are not effectively LSMs, especially due to the fact that in the past they could not provide a security blob while there is another LSM active. That changed in the recent years, the LSM stacking feature now makes it possible to stack together multiple LSMs, and allows them to provide a security blob for most kernel objects. While the LSM stacking feature has some limitations being worked out, it is already suitable to make IMA and EVM as LSMs. The main purpose of this patch set is to remove IMA and EVM function calls, hardcoded in the LSM infrastructure and other places in the kernel, and to register them as LSM hook implementations, so that those functions are called by the LSM infrastructure like other regular LSMs. This patch set introduces two new LSMs 'ima' and 'evm', so that functions can be registered to their respective LSM, and removes the 'integrity' LSM. integrity_kernel_module_request() was moved to IMA, since deadlock could occur only there. integrity_inode_free() was replaced with ima_inode_free() (EVM does not need to free memory). In order to make 'ima' and 'evm' independent LSMs, it was necessary to split integrity metadata used by both IMA and EVM, and to let them manage their own. The special case of the IMA_NEW_FILE flag, managed by IMA and used by EVM, was handled by introducing a new flag in EVM, EVM_NEW_FILE, managed by two additional LSM hooks, evm_post_path_mknod() and evm_file_release(), equivalent to their counterparts ima_post_path_mknod() and ima_file_free(). In addition to splitting metadata, it was decided to embed the evm_iint_inode structure into the inode security blob, since it is small and because anyway it cannot rely on IMA anymore allocating it (since it uses a different structure). On the other hand, to avoid memory pressure concerns, only a pointer to the ima_iint_cache structure is stored in the inode security blob, and the structure is allocated on demand, like before. Another follow-up change was removing the iint parameter from evm_verifyxattr(), that IMA used to pass integrity metadata to EVM. After splitting metadata, and aligning EVM_NEW_FILE with IMA_NEW_FILE, this parameter was not necessary anymore. The last part was to ensure that the order of IMA and EVM functions is respected after they become LSMs. Since the order of lsm_info structures in the .lsm_info.init section depends on the order object files containing those structures are passed to the linker of the kernel image, and since IMA is before EVM in the Makefile, that is sufficient to assert that IMA functions are executed before EVM ones. The patch set is organized as follows. Patches 1-9 make IMA and EVM functions suitable to be registered to the LSM infrastructure, by aligning function parameters. Patches 10-18 add new LSM hooks in the same places where IMA and EVM functions are called, if there is no LSM hook already. Patch 19 moves integrity_kernel_module_request() to IMA, as a prerequisite for removing the 'integrity' LSM. Patches 20-22 introduce the new standalone LSMs 'ima' and 'evm', and move hardcoded calls to IMA, EVM and integrity functions to those LSMs. Patches 23-24 remove the dependency on the 'integrity' LSM by splitting integrity metadata, so that the 'ima' and 'evm' LSMs can use their own. They also duplicate iint_lockdep_annotate() in ima_main.c, since the mutex field was moved from integrity_iint_cache to ima_iint_cache. Patch 25 finally removes the 'integrity' LSM, since 'ima' and 'evm' are now self-contained and independent. The patch set applies on top of lsm/next, commit 97280fa1ed94 ("Automated merge of 'dev' into 'next'"). Changelog: v9: - Add new Reviewed-by/Acked-by - Rewrite documentation of ima_kernel_module_request() (suggested by Stefan) - Move evm_inode_post_setxattr() registration after evm_inode_setxattr() (suggested by Stefan) v8: -

Move integrity_kernel_module_request() to IMA in a separate patch (suggested by Mimi) - Compile ima_kernel_module_request() if CONFIG_INTEGRITY_ASYMMETRIC_KEYS is enabled - Remove ima_inode_alloc_security() and ima_inode_free_security(), since the IMA integrity metadata is not fully embedded in the inode security blob -

Move integrity_kernel_module_request() to ima_main.c (renamed to ima_kernel_module_request()) - Split the integrity_iint_cache structure into ima_iint_cache and evm_iint_cache, so that IMA and EVM can use disjoint metadata and reserve space with the LSM infrastructure - Reserve space for the entire ima_iint_cache and evm_iint_cache structures, not just the pointer (suggested by Paul) - Introduce ima_inode_get_iint() and evm_inode_get_iint() to retrieve respectively the ima_iint_cache and evm_iint_cache structure from the security blob -

[PATCH 07/10] selftests/sched: Add a test to verify that DL server works with core scheduling

by Joel Fernandes (Google)

This test verifies that DL server infrastructure gives CFS tasks a fixed bandwidth even when RT tasks are being "core scheduled" on a core. Verify that they are getting the expected bandwidth (and thus not being starved). Also verified that not having core scheduling fixes makes the test fail as the CFS task gets no bandwidth. Sample output: # Runtime of PID 97 is 4.440000 seconds # Runtime of PID 98 is 4.560000 seconds # Runtime of PID 99 is 4.550000 seconds ok 1 PASS Notes about test that generated the sample output: The test runs for 12 seconds. We check the runtimes at 9 seconds. We expect the CFS task (PID 7) to get ~50% of the 9 seconds. The DL server is configured for 50% bandwidth. The RT tasks (PID 98, 99) each get 50% as well, because they run concurrently on 2 hyperthreads of a core.

[PATCH v4 0/7] Split a folio to any lower order folios

by Zi Yan

From: Zi Yan <ziy(a)nvidia.com> Hi all, File folio supports any order and multi-size THP is upstreamed[1], so both file and anonymous folios can be >0 order. Currently, split_huge_page() only splits a huge page to order-0 pages, but splitting to orders higher than 0 is going to better utilize large folios. In addition, Large Block Sizes in XFS support would benefit from it[2]. This patchset adds support for splitting a large folio to any lower order folios and uses it during file folio truncate operations. For Patch 6, Hugh did not like my approach to minimize the number of folios for truncate[3]. I would like to get more feedback, especially from FS people, on it to decide whether to keep it or not. The patchset is on top of mm-everything-2024-02-13-01-26. Changelog === Since v3 --- 1. Excluded shmem folios and pagecache folios without FS support from splitting to any order (per Hugh Dickins). 2. Allowed splitting anonymous large folio to any lower order since multi-size THP is upstreamed. 3. Adapted selftests code to new framework. Since v2 --- 1. Fixed an issue in __split_page_owner() introduced during my rebase Since v1 --- 1. Changed split_page_memcg() and split_page_owner() parameter to use order 2. Used folio_test_pmd_mappable() in place of the equivalent code Details === * Patch 1 changes split_page_memcg() to use order instead of nr_pages * Patch 2 changes split_page_owner() to use order instead of nr_pages * Patch 3 and 4 add new_order parameter split_page_memcg() and split_page_owner() and prepare for upcoming changes. * Patch 5 adds split_huge_page_to_list_to_order() to split a huge page to any lower order. The original split_huge_page_to_list() calls split_huge_page_to_list_to_order() with new_order = 0. * Patch 6 uses split_huge_page_to_list_to_order() in large pagecache folio truncation instead of split the large folio all the way down to order-0. * Patch 7 adds a test API to debugfs and test cases in split_huge_page_test selftests. Comments and/or suggestions are welcome.

[PATCH v3 0/7] of: populate of_root node if bootloader doesn't

by Stephen Boyd

Arch maintainers, please ack/review patches. This is a resend of a series from Frank last year[1]. I worked in Rob's review comments to unconditionally call unflatten_device_tree() and fixup/audit calls to of_have_populated_dt() so that behavior doesn't change. I need this series so I can add DT based tests in the clk framework. Either I can merge it through the clk tree once everyone is happy, or Rob can merge it through the DT tree and provide some branch so I can base clk patches on it. Changes from Frank's series[1]: * Add a DTB loaded kunit test * Make of_have_populated_dt() return false if the DTB isn't from the bootloader * Architecture calls made unconditional so that a root node is always made Changes from v2 (https://lore.kernel.org/r/20240130004508.1700335-1-sboyd@kernel.org): * Reorder patches to have OF changes largely first * No longer modify initial_boot_params if ACPI=y * Put arm64 patch back to v1 Changes from v1 (https://lore.kernel.org/r/20240112200750.4062441-1-sboyd@kernel.org): * x86 patch included * arm64 knocks out initial dtb if acpi is in use * keep Kconfig hidden but def_bool enabled otherwise Frank Rowand (2): of: Create of_root if no dtb provided by firmware of: unittest: treat missing of_root as error instead of fixing up Stephen Boyd (5): of: Always unflatten in unflatten_and_copy_device_tree() um: Unconditionally call unflatten_device_tree() x86/of: Unconditionally call unflatten_and_copy_device_tree() arm64: Unconditionally call unflatten_device_tree() of: Add KUnit test to confirm DTB is loaded arch/arm64/kernel/setup.c | 3 +- arch/um/kernel/dtb.c | 14 ++++---- arch/x86/kernel/devicetree.c | 24 +++++++------- drivers/of/.kunitconfig | 3 ++ drivers/of/Kconfig | 11 ++++++- drivers/of/Makefile | 4 ++- drivers/of/empty_root.dts | 6 ++++ drivers/of/fdt.c | 64 +++++++++++++++++++++++++++--------- drivers/of/of_test.c | 48 +++++++++++++++++++++++++++ drivers/of/platform.c | 3 -- drivers/of/unittest.c | 16 +++------ include/linux/of.h | 25 ++++++++------ 12 files changed, 158 insertions(+), 63 deletions(-) create mode 100644 drivers/of/.kunitconfig create mode 100644 drivers/of/empty_root.dts create mode 100644 drivers/of/of_test.c Cc: Anton Ivanov <anton.ivanov(a)cambridgegreys.com> Cc: Brendan Higgins <brendan.higgins(a)linux.dev> Cc: Catalin Marinas <catalin.marinas(a)arm.com> Cc: David Gow <davidgow(a)google.com> Cc: Frank Rowand <frowand.list(a)gmail.com> Cc: Johannes Berg <johannes(a)sipsolutions.net> Cc: Richard Weinberger <richard(a)nod.at> Cc: Rob Herring <robh+dt(a)kernel.org> Cc: Will Deacon <will(a)kernel.org> Cc: Thomas Gleixner <tglx(a)linutronix.de> Cc: Ingo Molnar <mingo(a)redhat.com> Cc: Borislav Petkov <bp(a)alien8.de> Cc: Dave Hansen <dave.hansen(a)linux.intel.com> Cc: <x86(a)kernel.org> Cc: "H.

[KTAP V2 PATCH v3] ktap_v2: add test metadata

by Rae Moar

Add specification for test metadata to the KTAP v2 spec. KTAP v1 only specifies the output format of very basic test information: test result and test name. Any additional test information either gets added to general diagnostic data or is not included in the output at all. The purpose of KTAP metadata is to create a framework to include and easily identify additional important test information in KTAP. KTAP metadata could include any test information that is pertinent for user interaction before or after the running of the test. For example, the test file path or the test speed. Since this includes a large variety of information, this specification will recognize notable types of KTAP metadata to ensure consistent format across test frameworks. See the full list of types in the specification. Example of KTAP Metadata: KTAP version 2 #:ktap_test: main #:ktap_arch: uml 1..1 KTAP version 2 #:ktap_test: suite_1 #:ktap_subsystem: example #:ktap_test_file: lib/test.c 1..2 ok 1 test_1 #:ktap_test: test_2 #:ktap_speed: very_slow # test_2 has begun #:custom_is_flaky: true ok 2 test_2 # suite_1 has passed ok 1 suite_1 The changes to the KTAP specification outline the format, location, and different types of metadata. Reviewed-by: David Gow <davidgow(a)google.com> Signed-off-by: Rae Moar <rmoar(a)google.com> --- Changes since v2: - Change format of metadata line from "# prefix_type: value" to "#:prefix_type: value". - Add examples of edge cases, such as diagnostic information interrupting metadata lines and lines in the wrong location, to the example in the specification. - Add current list of accepted prefixes. - Add notes on indentation and generated files. - Fix a few typos.

[PATCH v9 00/25] security: Move IMA and EVM to the LSM infrastructure

by Roberto Sassu

From: Roberto Sassu <roberto.sassu(a)huawei.com> IMA and EVM are not effectively LSMs, especially due to the fact that in the past they could not provide a security blob while there is another LSM active. That changed in the recent years, the LSM stacking feature now makes it possible to stack together multiple LSMs, and allows them to provide a security blob for most kernel objects. While the LSM stacking feature has some limitations being worked out, it is already suitable to make IMA and EVM as LSMs. The main purpose of this patch set is to remove IMA and EVM function calls, hardcoded in the LSM infrastructure and other places in the kernel, and to register them as LSM hook implementations, so that those functions are called by the LSM infrastructure like other regular LSMs. This patch set introduces two new LSMs 'ima' and 'evm', so that functions can be registered to their respective LSM, and removes the 'integrity' LSM. integrity_kernel_module_request() was moved to IMA, since deadlock could occur only there. integrity_inode_free() was replaced with ima_inode_free() (EVM does not need to free memory). In order to make 'ima' and 'evm' independent LSMs, it was necessary to split integrity metadata used by both IMA and EVM, and to let them manage their own. The special case of the IMA_NEW_FILE flag, managed by IMA and used by EVM, was handled by introducing a new flag in EVM, EVM_NEW_FILE, managed by two additional LSM hooks, evm_post_path_mknod() and evm_file_release(), equivalent to their counterparts ima_post_path_mknod() and ima_file_free(). In addition to splitting metadata, it was decided to embed the evm_iint_inode structure into the inode security blob, since it is small and because anyway it cannot rely on IMA anymore allocating it (since it uses a different structure). On the other hand, to avoid memory pressure concerns, only a pointer to the ima_iint_cache structure is stored in the inode security blob, and the structure is allocated on demand, like before. Another follow-up change was removing the iint parameter from evm_verifyxattr(), that IMA used to pass integrity metadata to EVM. After splitting metadata, and aligning EVM_NEW_FILE with IMA_NEW_FILE, this parameter was not necessary anymore. The last part was to ensure that the order of IMA and EVM functions is respected after they become LSMs. Since the order of lsm_info structures in the .lsm_info.init section depends on the order object files containing those structures are passed to the linker of the kernel image, and since IMA is before EVM in the Makefile, that is sufficient to assert that IMA functions are executed before EVM ones. The patch set is organized as follows. Patches 1-9 make IMA and EVM functions suitable to be registered to the LSM infrastructure, by aligning function parameters. Patches 10-18 add new LSM hooks in the same places where IMA and EVM functions are called, if there is no LSM hook already. Patch 19 moves integrity_kernel_module_request() to IMA, as a prerequisite for removing the 'integrity' LSM. Patches 20-22 introduce the new standalone LSMs 'ima' and 'evm', and move hardcoded calls to IMA, EVM and integrity functions to those LSMs. Patches 23-24 remove the dependency on the 'integrity' LSM by splitting integrity metadata, so that the 'ima' and 'evm' LSMs can use their own. They also duplicate iint_lockdep_annotate() in ima_main.c, since the mutex field was moved from integrity_iint_cache to ima_iint_cache. Patch 25 finally removes the 'integrity' LSM, since 'ima' and 'evm' are now self-contained and independent. The patch set applies on top of lsm/dev, commit f1bb47a31dff ("lsm: new security_file_ioctl_compat() hook"). The linux-integrity/next-integrity at commit c00f94b3a5be ("overlay: disable EVM") was merged. Changelog: v8: - Restore dynamic allocation of IMA integrity metadata, and store only the pointer in the inode security blob - Select SECURITY_PATH both in IMA and EVM - Rename evm_file_free() to evm_file_release() - Unconditionally register evm_post_path_mknod() - Introduce the new ima_iint.c file for the management of IMA integrity metadata - Introduce ima_inode_set_iint()/ima_inode_get_iint() in ima.h to respectively store/retrieve the IMA integrity metadata pointer - Replace ima_iint_inode() with ima_inode_get() and ima_iint_find(), with same behavior of integrity_inode_get() and integrity_iint_find() - Initialize the ima_iint_cache in ima_iintcache_init() and call it from init_ima_lsm() - Move integrity_kernel_module_request() to IMA in a separate patch (suggested by Mimi) - Compile ima_kernel_module_request() if CONFIG_INTEGRITY_ASYMMETRIC_KEYS is enabled - Remove ima_inode_alloc_security() and ima_inode_free_security(), since the IMA integrity metadata is not fully embedded in the inode security blob - Fixed the missed initialization of ima_iint_cache in process_measurement() and __ima_inode_hash() - Add a sentence in 'evm: Move to LSM infrastructure' to mention about moving evm_inode_remove_acl(), evm_inode_post_remove_acl() and evm_inode_post_set_acl() to evm_main.c - Add a sentence in 'ima: Move IMA-Appraisal to LSM infrastructure' to mention about moving ima_inode_remove_acl() to ima_appraise.c v7: - Use return instead of goto in __vfs_removexattr_locked() (suggested by Casey) - Clarify in security/integrity/Makefile that the order of 'ima' and 'evm' LSMs depends on the order in which IMA and EVM are compiled - Move integrity_iint_cache flags to ima.h and evm.h in security/ and duplicate IMA_NEW_FILE to EVM_NEW_FILE - Rename evm_inode_get_iint() to evm_iint_inode() and ima_inode_get_iint() to ima_iint_inode(), check if inode->i_security is NULL, and just return the pointer from the inode security blob - Restore the non-NULL checks after ima_iint_inode() and evm_iint_inode() (suggested by Casey) - Introduce evm_file_free() to clear EVM_NEW_FILE - Remove comment about LSM_ORDER_LAST not guaranteeing the order of 'ima' and 'evm' LSMs - Lock iint->mutex before reading IMA_COLLECTED flag in __ima_inode_hash() and restored ima_policy_flag check - Remove patch about the hardcoded ordering of 'ima' and 'evm' LSMs in security.c - Add missing ima_inode_free_security() to free iint->ima_hash - Add the cases for LSM_ID_IMA and LSM_ID_EVM in lsm_list_modules_test.c - Mention about the change in IMA and EVM post functions for private inodes v6: - See v7 v5: - Rename security_file_pre_free() to security_file_release() and the LSM hook file_pre_free_security to file_release (suggested by Paul) - Move integrity_kernel_module_request() to ima_main.c (renamed to ima_kernel_module_request()) - Split the integrity_iint_cache structure into ima_iint_cache and evm_iint_cache, so that IMA and EVM can use disjoint metadata and reserve space with the LSM infrastructure - Reserve space for the entire ima_iint_cache and evm_iint_cache structures, not just the pointer (suggested by Paul) - Introduce ima_inode_get_iint() and evm_inode_get_iint() to retrieve respectively the ima_iint_cache and evm_iint_cache structure from the security blob -

Introduce the evm_post_path_mknod() to set the IMA_NEW_FILE flag - Register the inode_alloc_security LSM hook in IMA and EVM to initialize the respective integrity metadata structures - Remove the 'integrity' LSM completely and instead make 'ima' and 'evm' proper standalone LSMs - Add the inode parameter to ima_get_verity_digest(), since the inode field is not present in ima_iint_cache - Move iint_lockdep_annotate() to ima_main.c (renamed to ima_iint_lockdep_annotate()) - Remove ima_get_lsm_id() and evm_get_lsm_id(), since IMA and EVM directly register the needed LSM hooks - Enforce 'ima' and 'evm' LSM ordering at LSM infrastructure level v4: - Improve short and long description of security_inode_post_create_tmpfile(), security_inode_post_set_acl(), security_inode_post_remove_acl() and security_file_post_open() (suggested by Mimi) -
