[PATCH v2 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 v2 that addresses issues pointed out in the first version that was posted as an RFC: https://lore.kernel.org/lkml/20220519092343.2776414-1-javierm@redhat.com/ [0]: https://github.com/ostreedev/ostree [1]: https://github.com/ostreedev/ostree/issues/1649 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] selftest/powerpc/pmu/ebb: remove fixed_instruction.S

by Madhavan Srinivasan

Commit 3752e453f6ba ("selftests/powerpc: Add tests of PMU EBBs") added selftest testcases to verify EBB interface. instruction_count_test.c testcase needs a fixed loop function to count overhead. Instead of using the thirty_two_instruction_loop() in fixed_instruction_loop.S in ebb folder, file is linked with thirty_two_instruction_loop() in loop.S from top folder. Since fixed_instruction_loop.S not used, patch removes the file.

[PATCH bpf-next 0/4] bpf: verifier: remove redundant opcode checks

by Shung-Hsi Yu

This patch set aims to remove opcode checks in BPF verifier that have become redundant since commit 5e581dad4fec ("bpf: make unknown opcode handling more robust"), either remove them entirely, or turn them into comments in places where the redundancy may not be clear. The exceptions here are opcode check for BPF_LD_{ABS,IND} and BPF_JMP_{JA,CALL,EXIT}; they cover opcode validation not done in bpf_opcode_in_insntable() so is not removed. After apply the patch set test_verifier passes and does not need further modification: Summary: 1348 PASSED, 635 SKIPPED, 0 FAILED Also, add comments at places that I find confusing while working on the removal, namely: 1. resolve_pseudo_ldimm64() also validates opcode 2. BPF_SIZE check in check_ld_imm() guards against JMP to the 2nd BPF_LD_IMM64 instruction 3. reason behind why ld_imm64 test cases should be rejected by the verifier Shung-Hsi Yu (4): bpf: verifier: update resolve_pseudo_ldimm64() comment bpf: verifier: explain opcode check in check_ld_imm() bpf: verifier: remove redundant opcode checks selftests/bpf: add reason of rejection in ld_imm64 kernel/bpf/verifier.c | 33 ++++++++----------- .../testing/selftests/bpf/verifier/ld_imm64.c | 20 ++++++----- 2 files changed, 25 insertions(+), 28 deletions(-) base-commit: 68084a13642001b73aade05819584f18945f3297 -- 2.36.1
