kbuild problem: ERROR: modpost: missing MODULE_LICENSE() in drivers/iio/afe/iio-rescale.o

by Randy Dunlap

Hi, In March I reported that a randconfig build complained: ERROR: modpost: missing MODULE_LICENSE() in drivers/iio/afe/iio-rescale.o (https://lore.kernel.org/all/16509fb6-e40c-e31b-2c80-264c44b0beb9@infradead.…) I am still seeing this problem so I tried to dig into it a bit. However, I don't see why get_next_modinfo() and friends don't find the MODULE_LICENSE() since it is in the iio-rescale.o file. (BTW, I see this build error on many different $ARCH [around 15 tested] and with 2 different versions of GCC.) Q1: Is modpost checking both vmlinux and iio-rescale.o for modinfo license strings? It looks like it is, because it appears (?) that modpost is looking at drivers/iio/test/iio-test-rescale.o (<<<<< a kunit test, which is builtin in my .config) and at drivers/iio/afe/iio-rescale.o (which is built as a loadable module). Is this confusing modpost? I renamed drivers/iio/afe/iio-rescale.c to afe-rescale.c and changed its Makefile entry accordingly and the MODULE_LICENSE error goes away. Is this a modpost error or is kunit messing things up? thanks for looking. -- ~Randy

[PATCH seccomp] selftests/seccomp: Fix compile warning when CC=clang

by YiFei Zhu

clang has -Wconstant-conversion by default, and the constant 0xAAAAAAAAA (9 As) being converted to an int, which is generally 32 bits, results in the compile warning: clang -Wl,-no-as-needed -Wall -isystem ../../../../usr/include/ -lpthread seccomp_bpf.c -lcap -o seccomp_bpf seccomp_bpf.c:812:67: warning: implicit conversion from 'long' to 'int' changes value from 45812984490 to -1431655766 [-Wconstant-conversion] int kill = kill_how == KILL_PROCESS ?

[PATCH v1] selftests/kselftest: Make failed tests exit with 1

by Mickaël Salaün

To check that tests are passing we must parse the kselftest runner output. It is much more convenient to check the return value of the runner instead: 0 is OK, and 1 implies one or more errors. This has an impact on the kselftest's gen_tar bundle and the run_tests make target. Backporting this change would be useful to consistently test older kernels as well.

[PATCH v3 0/3] fat: add support for the renameat2 RENAME_EXCHANGE flag

by Javier Martinez Canillas

Hello, This series add support for the renameat2 system call RENAME_EXCHANGE flag (which allows to atomically replace two paths) to the vfat filesystem code. There are many use cases for this, but we are particularly interested in making possible for vfat filesystems to be part of OSTree [0] deployments. Currently OSTree relies on symbolic links to make the deployment updates an atomic transactional operation. But RENAME_EXCHANGE could be used [1] to achieve a similar level of robustness when using a vfat filesystem. Patch #1 is just a preparatory patch to introduce the RENAME_EXCHANGE support in patch #2 and finally patch #3 adds some kselftests to test it. This is a v3 that addresses issues pointed out in the second version posted: https://lkml.org/lkml/2022/5/24/137 [0]: https://github.com/ostreedev/ostree [1]: https://github.com/ostreedev/ostree/issues/1649 Changes in v3: - Add a .gitignore for the rename_exchange binary (Muhammad Usama Anjum). - Include $(KHDR_INCLUDES) instead of hardcoding a relative path in Makefile (Muhammad Usama Anjum). Changes in v2: - Only update the new_dir inode version and timestamps if != old_dir (Alex Larsson). - Add some helper functions to avoid duplicating code (OGAWA Hirofumi). - Use braces for multi-lines blocks even if are one statement (OGAWA Hirofumi). - Mention in commit message that the operation is as transactional as possible but within the vfat limitations of not having a journal (Colin Walters). - Call sync to flush the page cache before checking the file contents (Alex Larsson). - Drop RFC prefix since the patches already got some review.

[PATCH v2] selftests/net: enable lo.accept_local in psock_snd test

by Yun Lu

From: luyun <luyun(a)kylinos.cn> The psock_snd test sends and recieves packets over loopback, and the test results depend on parameter settings: Set rp_filter=0, or set rp_filter=1 and accept_local=1 so that the test will pass. Otherwise, this test will fail with Resource temporarily unavailable: sudo ./psock_snd.sh dgram tx: 128 rx: 142 ./psock_snd: recv: Resource temporarily unavailable For most distro kernel releases(like Ubuntu or Centos), the parameter rp_filter is enabled by default, so it's necessary to enable the parameter lo.accept_local in psock_snd test. And this test runs inside a netns, changing a sysctl is fine. v2: add detailed description.
