[PATCH net-next v3 6/7] selftests: net: lib: Add kill_process

by Petr Machata

A number of selftests run processes in the background and need to kill them afterwards. Instead for everyone to open-code the kill / wait / redirect mantra, add a helper in net/lib.sh. Convert existing open-code sites.

[PATCH net-next v3 5/7] selftests: net: lib: Move checks from forwarding/lib.sh here

by Petr Machata

For logging to be useful, something has to set RET and retmsg by calling ret_set_ksft_status(). There is a suite of functions to that end in forwarding/lib: check_err, check_fail et.al. Move them to net/lib.sh so that every net test can use them. Existing lib.sh users might be using these same names for their functions. However lib.sh is always sourced near the top of the file (checked), and whatever new definitions will simply override the ones provided by lib.sh.

[PATCH net-next v3 4/7] selftests: net: lib: Move tests_run from forwarding/lib.sh here

It would be good to use the same mechanism for scheduling and dispatching general net tests as the many forwarding tests already use. To that end, move the logging helpers to net/lib.sh so that every net test can use them. Existing lib.sh users might be using the name themselves.

[PATCH net-next v3 3/7] selftests: net: lib: Move logging from forwarding/lib.sh here

by Petr Machata

Many net selftests invent their own logging helpers. These really should be in a library sourced by these tests. Currently forwarding/lib.sh has a suite of perfectly fine logging helpers, but sourcing a forwarding/ library from a higher-level directory smells of layering violation. In this patch, move the logging helpers to net/lib.sh so that every net test can use them. Together with the logging helpers, it's also necessary to move pause_on_fail(), and EXIT_STATUS and RET. Existing lib.sh users might be using these same names for their functions or variables. However lib.sh is always sourced near the top of the file (checked), and whatever new definitions will simply override the ones provided by lib.sh.

[PATCH v7 0/5] selftests: kvm: s390: Add ucontrol memory selftests

by Christoph Schlameuss

This patch series adds a some not yet picked selftests to the kvm s390x selftest suite. The additional test cases are covering: * Assert KVM_EXIT_S390_UCONTROL exit on not mapped memory access * Assert functionality of storage keys in ucontrol VM * Assert that memory region operations are rejected for ucontrol VMs Running the test cases requires sys_admin capabilities to start the ucontrol VM. This can be achieved by running as root or with a command like: sudo setpriv --reuid nobody --inh-caps -all,+sys_admin \ --ambient-caps -all,+sys_admin --bounding-set -all,+sys_admin \ ./ucontrol_test --- The patches in this series have been part of the previous patch series. The test cases added here do depend on the fixture added in the earlier patches. From v5 PATCH 7-9 the segment and page table generation has been removed and DAT has been disabled. Since DAT is not necessary to validate the KVM code. https://lore.kernel.org/kvm/20240807154512.316936-1-schlameuss@linux.ibm.co… v7: - skip uc_skey test when execution is in vsie v6: - add instruction intercept handling for skey specific instructions (iske, sske, rrbe) in addition to kss intercept to work properly on all machines - reorder local variables - fixup some method comments - add a patch correcting the IP.b value length a debug message v5: - rebased to current upstream master - corrected assertion on 0x00 to 0 - reworded fixup commit so that it can be merged on top of current upstream v4: - fix whitespaces in pointer function arguments (thanks Claudio) - fix whitespaces in comments (thanks Janosch) v3: - fix skey assertion (thanks Claudio) - introduce a wrapper around UCAS map and unmap ioctls to improve readability (Claudio) - add an displacement to accessed memory to assert translation intercepts actually point to segments to the uc_map_unmap test - add an misaligned failing mapping try to the uc_map_unmap test v2: - Reenable KSS intercept and handle it within skey test. - Modify the checked register between storing (sske) and reading (iske) it within the test program to make sure the. - Add an additional state assertion in the end of uc_skey - Fix some typos and white spaces. v1: - Remove segment and page table generation and disable DAT. This is not necessary to validate the KVM code.

[PATCH] kunit: string-stream: Fix a UAF bug in kunit_init_suite()

by Jinjie Ruan

In kunit_debugfs_create_suite(), if alloc_string_stream() fails in the kunit_suite_for_each_test_case() loop, the "suite->log = stream" has assigned before, and the error path only free the suite->log's stream memory but not set it to NULL in string_stream_destroy(), so the later string_stream_clear() of suite->log in kunit_init_suite() will cause below UAF bug. Set stream pointer to NULL after free in string_stream_destroy() to fix it.
