019baf63 - selftests/binderfs: use the Makefile's rules, not Make's implicit rules

Fri, 03 May 2024 01:58:20 +0000

selftests/binderfs: use the Makefile's rules, not Make's implicit rulesFirst of all, in order to build with clang at all, one must first applyValentin Obst's build fix for LLVM [1]. Once that is done, then whenbuilding with clang, via: make LLVM=1 -C tools/testing/selftests...the following error occurs: clang: error: cannot specify -o when generating multiple output filesThis is because clang, unlike gcc, won't accept invocations of thisform: clang file1.c header2.hWhile trying to fix this, I noticed that:a) selftests/lib.mk already avoids the problem, andb) The binderfs Makefile indavertently bypasses the selftests/lib.mkbuild system, and quitely uses Make's implicit build rules for .c filesinstead.The Makefile attempts to set up both a dependency and a source file,neither of which was needed, because lib.mk is able to automaticallyhandle both. This line: binderfs_test: binderfs_test.c...causes Make's implicit rules to run, which builds binderfs_testwithout ever looking at lib.mk.Fix this by simply deleting the "binderfs_test:" Makefile target andletting lib.mk handle it instead.[1] https://lore.kernel.org/all/20240329-selftests-libmk-llvm-rfc-v1-1-2f9ed7d1c49f@valentinobst.de/Fixes: 6e29225af902 ("binderfs: port tests to test harness infrastructure")Cc: Christian Brauner Signed-off-by: John Hubbard Reviewed-by: Christian Brauner Signed-off-by: Shuah Khan List of files: /linux-6.15/tools/testing/selftests/filesystems/binderfs/Makefile

75abec73 - selftests: add binderfs selftests

Thu, 17 Jan 2019 11:48:54 +0000

selftests: add binderfs selftestsThis adds the promised selftest for binderfs. It will verify the followingthings:- binderfs mounting works- binder device allocation works- performing a binder ioctl() request through a binderfs device works- binder device removal works- binder-control removal fails- binderfs unmounting worksThe tests are performed both privileged and unprivileged. The latterverifies that binderfs behaves correctly in user namespaces.Cc: Todd Kjos Signed-off-by: Christian Brauner Acked-by: Shuah Khan Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/tools/testing/selftests/filesystems/binderfs/Makefile
