[PATCH 0/4] rseq selftests updates

by Mathieu Desnoyers

Hi Shuah, This series contains updates to the rseq selftests. * A typo in the Makefile prevents the basic_percpu_ops_mm_cid_test to use the mm_cid field. * Fix load-acquire/store-release macros which were buggy on arm64. (this depends on commit "Implement rseq_unqual_scalar_typeof"). * The change "Use rseq_unqual_scalar_typeof in macros" is not a fix per se, but improves the assembler generated. Can you pick these in the selftests tree please ? Thanks, Mathieu Mathieu Desnoyers (4): selftests/rseq: Fix CID_ID typo in Makefile selftests/rseq: Implement rseq_unqual_scalar_typeof selftests/rseq: Fix arm64 buggy load-acquire/store-release macros selftests/rseq: Use rseq_unqual_scalar_typeof in macros tools/testing/selftests/rseq/Makefile | 2 +- tools/testing/selftests/rseq/compiler.h | 26 ++++++++++ tools/testing/selftests/rseq/rseq-arm.h | 4 +- tools/testing/selftests/rseq/rseq-arm64.h | 58 ++++++++++++----------- tools/testing/selftests/rseq/rseq-mips.h | 4 +- tools/testing/selftests/rseq/rseq-ppc.h | 4 +- tools/testing/selftests/rseq/rseq-riscv.h | 6 +-- tools/testing/selftests/rseq/rseq-s390.h | 4 +- tools/testing/selftests/rseq/rseq-x86.h | 4 +- 9 files changed, 70 insertions(+), 42 deletions(-) -- 2.25.1

[PATCH bpf-next v3 0/7] Add SO_REUSEPORT support for TC bpf_sk_assign

by Lorenz Bauer

We want to replace iptables TPROXY with a BPF program at TC ingress. To make this work in all cases we need to assign a SO_REUSEPORT socket to an skb, which is currently prohibited. This series adds support for such sockets to bpf_sk_assing. I did some refactoring to cut down on the amount of duplicate code. The key to this is to use INDIRECT_CALL in the reuseport helpers. To show that this approach is not just beneficial to TC sk_assign I removed duplicate code for bpf_sk_lookup as well. Changes from v1: - Correct commit abbrev length (Kuniyuki) - Reduce duplication (Kuniyuki) - Add checks on sk_state (Martin) - Split exporting inet[6]_lookup_reuseport into separate patch (Eric) Joint work with Daniel Borkmann. Signed-off-by: Lorenz Bauer <lmb(a)isovalent.com> --- Changes in v3: - Fix warning re udp_ehashfn and udp6_ehashfn (Simon) - Return higher scoring connected UDP reuseport sockets (Kuniyuki) - Fix ipv6 module builds - Link to v2: https://lore.kernel.org/r/20230613-so-reuseport-v2-0-b7c69a342613@isovalent… --- Daniel Borkmann (1): selftests/bpf: Test that SO_REUSEPORT can be used with sk_assign helper Lorenz Bauer (6): udp: re-score reuseport groups when connected sockets are present net: export inet_lookup_reuseport and inet6_lookup_reuseport net: document inet[6]_lookup_reuseport sk_state requirements net: remove duplicate reuseport_lookup functions net: remove duplicate sk_lookup helpers bpf, net: Support SO_REUSEPORT sockets with bpf_sk_assign include/net/inet6_hashtables.h | 84 ++++++++- include/net/inet_hashtables.h | 77 +++++++- include/net/sock.h | 7 +- include/net/udp.h | 8 + include/uapi/linux/bpf.h | 3 - net/core/filter.c | 2 - net/ipv4/inet_hashtables.c | 70 +++++--- net/ipv4/udp.c | 88 ++++----- net/ipv6/inet6_hashtables.c | 73 +++++--- net/ipv6/udp.c | 98 ++++------ tools/include/uapi/linux/bpf.h | 3 - tools/testing/selftests/bpf/network_helpers.c | 3 + .../selftests/bpf/prog_tests/assign_reuse.c | 197 +++++++++++++++++++++ .../selftests/bpf/progs/test_assign_reuse.c | 142 +++++++++++++++ 14 files changed, 676 insertions(+), 179 deletions(-) --- base-commit: 970308a7b544fa1c7ee98a2721faba3765be8dd8 change-id: 20230613-so-reuseport-e92c526173ee Best regards, -- Lorenz Bauer <lmb(a)isovalent.com>

[PATCH v3 0/9] cgroup/cpuset: Support remote partitions

by Waiman Long

v3: - [v2] https://lore.kernel.org/lkml/20230531163405.2200292-1-longman@redhat.com/ - Change the new control file from root-only "cpuset.cpus.reserve" to non-root "cpuset.cpus.exclusive" which lists the set of exclusive CPUs distributed down the hierarchy. - Add a patch to restrict boot-time isolated CPUs to isolated partitions only. - Update the test_cpuset_prs.sh test script and documentation accordingly. v2: - [v1] https://lore.kernel.org/lkml/20230412153758.3088111-1-longman@redhat.com/ - Dropped the special "isolcpus" partition in v1 - Add the root only "cpuset.cpus.reserve" control file for reserving CPUs used for remote isolated partitions. - Update the test_cpuset_prs.sh test script and documentation accordingly. This patch series introduces a new cpuset control file "cpuset.cpus.exclusive" which must be a subset of "cpuset.cpus" and the parent's "cpuset.cpus.exclusive". This control file lists the exclusive CPUs to be distributed down the hierarchy. Any one of the exclusive CPUs can only be distributed to at most one child cpuset. Unlike "cpuset.cpus", invalid input to "cpuset.cpus.exclusive" will be rejected with an error. This new control file has no effect on the behavior of the cpuset until it turns into a partition root. At that point, its effective CPUs will be set to its exclusive CPUs unless some of them are offline. This patch series also introduces a new category of cpuset partition called remote partitions. The existing partition category where the partition roots have to be clustered around the root cgroup in a hierarchical way is now referred to as local partitions. A remote partition can be formed far from the root cgroup with no partition root parent. While local partitions can be created without touching "cpuset.cpus.exclusive" as it can be set automatically if a cpuset becomes a local partition root. Properly set "cpuset.cpus.exclusive" values down the hierarchy are required to create a remote partition. Both scheduling and isolated partitions can be formed in a remote partition. A local partition can be created under a remote partition. A remote partition, however, cannot be formed under a local partition for now. Modern container orchestration tools like Kubernetes use the cgroup hierarchy to manage different containers. And it is relying on other middleware like systemd to help managing it. If a container needs to use isolated CPUs, it is hard to get those with the local partitions as it will require the administrative parent cgroup to be a partition root too which tool like systemd may not be ready to manage. With this patch series, we allow the creation of remote partition far from the root. The container management tool can manage the "cpuset.cpus.exclusive" file without impacting the other cpuset files that are managed by other middlewares. Of course, invalid "cpuset.cpus.exclusive" values will be rejected and changes to "cpuset.cpus" can affect the value of "cpuset.cpus.exclusive" due to the requirement that it has to be a subset of the former control file.
