2023-12-01selftests/bpf: Add test that uses fsverity and xattr to sign a fileSong Liu5-8/+280
This selftests shows a proof of concept method to use BPF LSM to enforce file signature. This test is added to verify_pkcs7_sig, so that some existing logic can be reused. This file signature method uses fsverity, which provides reliable and efficient hash (known as digest) of the file. The file digest is signed with asymmetic key, and the signature is stored in xattr. At the run time, BPF LSM reads file digest and the signature, and then checks them against the public key. Note that this solution does NOT require FS_VERITY_BUILTIN_SIGNATURES. fsverity is only used to provide file digest. The signature verification and access control is all implemented in BPF LSM.

Add selftests for two new filesystem kfuncs: 1. bpf_get_file_xattr 2. bpf_get_fsverity_digest These tests simply make sure the two kfuncs work. Another selftest will be added to demonstrate how to use these kfuncs to verify file signature. CONFIG_FS_VERITY is added to selftests config. However, this is not sufficient to guarantee bpf_get_fsverity_digest works. This is because fsverity need to be enabled at file system level (for example, with tune2fs on ext4). If local file system doesn't have this feature enabled, just skip the test.

The main changes are: 1) Add initial TX metadata implementation for AF_XDP with support in mlx5 and stmmac drivers. Two types of offloads are supported right now, that is, TX timestamp and TX checksum offload, from Stanislav Fomichev with stmmac implementation from Song Yoong Siang. 2) Change BPF verifier logic to validate global subprograms lazily instead of unconditionally before the main program, so they can be guarded using BPF CO-RE techniques, from Andrii Nakryiko. 3) Add BPF link_info support for uprobe multi link along with bpftool integration for the latter, from Jiri Olsa. 4) Use pkg-config in BPF selftests to determine ld flags which is in particular needed for linking statically, from Akihiko Odaki. 5) Fix a few BPF selftest failures to adapt to the upcoming LLVM18, from Yonghong Song. * tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (30 commits) bpf/tests: Remove duplicate JSGT tests selftests/bpf: Add TX side to xdp_hw_metadata selftests/bpf: Convert xdp_hw_metadata to XDP_USE_NEED_WAKEUP selftests/bpf: Add TX side to xdp_metadata selftests/bpf: Add csum helpers selftests/xsk: Support tx_metadata_len xsk: Add option to calculate TX checksum in SW xsk: Validate xsk_tx_metadata flags xsk: Document tx_metadata_len layout net: stmmac: Add Tx HWTS support to XDP ZC net/mlx5e: Implement AF_XDP TX timestamp and checksum offload tools: ynl: Print xsk-features from the sample xsk: Add TX timestamp and TX checksum offload support xsk: Support tx_metadata_len selftests/bpf: Use pkg-config for libelf selftests/bpf: Override PKG_CONFIG for static builds selftests/bpf: Choose pkg-config for the target bpftool: Add support to display uprobe_multi links selftests/bpf: Add link_info test for uprobe_multi link selftests/bpf: Use bpf_link__destroy in fill_link_info tests ... ==================== Conflicts: Documentation/netlink/specs/netdev.yaml: 839ff60df3ab ("net: page_pool: add nlspec for basic access to page pools") 48eb03dd2630 ("xsk: Add TX timestamp and TX checksum offload support") https://lore.kernel.org/all/[email protected]/ While at it also regen, tree is dirty after: 48eb03dd2630 ("xsk: Add TX timestamp and TX checksum offload support") looks like code wasn't re-rendered after "render-max" was removed.

2023-11-30kselftest/vDSO: Use ksft_print_msg() rather than printf in vdso_test_abiMark Brown1-2/+2
There are a couple of raw printf() calls in vdso_test_abi which result in non KTAP conforment output such as [vDSO kselftest] VDSO_VERSION: LINUX_2.6 Convert them to use ksft_print_msg() so that they don't cause confusion for parsers.

2023-11-30kselftest/vDSO: Fix message formatting for clock_id loggingMark Brown1-1/+1
When logging the ID of the currently tested clock vdso_test_clock() puts a spurious newline at the start of the format string resulting in output such as # clock_id: CLOCK_BOOTTIME which is a valid but empty KTAP informational message followed by a non conferment output line. Remove the initial newline to create a more KTAP friendly # clock_id: CLOCK_BOOTTIME Signed-off-by: Mark Brown <[email protected]> Signed-off-by: Shuah Khan <[email protected]>
2023-11-30kselftest/vDSO: Make test name reporting for vdso_abi_test tooling friendlyMark Brown1-30/+36
The test results from vdso_abi_test are all formatted using a series of macros: #define VDSO_TEST_PASS_MSG() "\n%s(): PASS\n", __func__ #define VDSO_TEST_FAIL_MSG(x) "\n%s(): %s FAIL\n", __func__, x #define VDSO_TEST_SKIP_MSG(x) "\n%s(): SKIP: Could not find %s\n", __func__, x which don't play nicely with automated KTAP parsers since the actual KTAP lines are in the form ok 1 with no test name and we get an additional log line such as vdso_test_gettimeofday(): PASS with no preceeding # as KTAP requires. The lack of a test name means that many automation systems will have a hard time distinguishing between the different tests or correlating results between runs, the lack of # is less severe but could potentially cause confusion. Fix these issues by rewriting all the result reporting to include both the vDSO function name being tested and (where there is one) the name of the clock being tested in the main KTAP line. Since we have tests both with and without a specific clock we abandon the helper macros and just put the format strings used directly in the ksft_ API calls. When we fail to look up the relevant vDSO symbol we add a separate print statement explaining why the skip is being done. This gives output such as: ok 1 __vdso_gettimeofday # clock_id: CLOCK_REALTIME # The time is 1700673118.58091596 ok 2 __vdso_clock_gettime CLOCK_REALTIME which is much easier for test automation to work with.

2023-11-30selftests:x86: Fix Format String Warnings in lam.cangquan yu1-2/+2
This commit addresses compiler warnings in lam.c related to the usage of non-literal format strings without format arguments in the 'run_test' function. Warnings fixed: - Resolved warnings indicating that 'ksft_test_result_skip' and 'ksft_test_result' were called with 't->msg' as a format string without accompanying format arguments. Changes made: - Modified the calls to 'ksft_test_result_skip' and 'ksft_test_result' to explicitly include a format specifier ("%s") for 't->msg'. - This ensures that the string is safely treated as a format argument, adhering to safer coding practices and resolving the compiler warnings.

2023-11-30selftests/breakpoints: Fix format specifier in ksft_print_msg in ↵angquan yu1-1/+1
step_after_suspend_test.c In the function 'tools/testing/selftests/breakpoints/run_test' within step_after_suspend_test.c, the ksft_print_msg function call incorrectly used '$s' as a format specifier. This commit corrects this typo to use the proper '%s' format specifier, ensuring the error message from waitpid() is correctly displayed. The issue manifested as a compilation warning (too many arguments for format [-Wformat-extra-args]), potentially obscuring actual runtime errors and complicating debugging processes. This fix enhances the clarity of error messages during test failures and ensures compliance with standard C format string conventions.

2023-11-30selftests:breakpoints: Fix Format String Warning in breakpoint_testangquan yu1-2/+2
This commit resolves a compiler warning regardingthe use of non-literal format strings in breakpoint_test.c. The functions `ksft_test_result_pass` and `ksft_test_result_fail` were previously called with a variable `msg` directly, which could potentially lead to format string vulnerabilities. Changes made: - Modified the calls to `ksft_test_result_pass` and `ksft_test_result_fail` by adding a "%s" format specifier. This explicitly declares `msg` as a string argument, adhering to safer coding practices and resolving the compiler warning. This change does not affect the functional behavior of the code but ensures better code safety and compliance with recommended C programming standards. The previous warning is "breakpoint_test.c:287:17: warning: format not a string literal and no format arguments [-Wformat-security] 287 | ksft_test_result_pass(msg); | ^~~~~~~~~~~~~~~~~~~~~ breakpoint_test.c:289:17: warning: format not a string literal and no format arguments [-Wformat-security] 289 | ksft_test_result_fail(msg); | " Signed-off-by: angquan yu <[email protected]> Signed-off-by: Shuah Khan <[email protected]>
