[PATCH v11 0/8] cgroup/cpuset: cpu partition code enhancements

by Waiman Long

v11: - Fix incorrect spacing in patch 7 and include documentation suggestions by Michal. - Move partition_is_populated() check to the last one in list of conditions to be checked. v10: - Relax constraints for changes made to "cpuset.cpus" and "cpuset.cpus.partition" as suggested. Now almost all changes are allowed. - Add patch 1 to signal that we may need to do additional work in the future to relax the constraint that tasks' cpumask may need some adjustment if child partitions are present. - Add patch 2 for miscellaneous cleanups. This patchset include the following enhancements to the cpuset v2 partition code. 1) Allow partitions that have no task to have empty effective cpus. 2) Relax the constraints on what changes are allowed in cpuset.cpus and cpuset.cpus.partition. However, the partition remain invalid until the constraints of a valid partition root is satisfied. 3) Add a new "isolated" partition type for partitions with no load balancing which is available in v1 but not yet in v2. 4) Allow the reading of cpuset.cpus.partition to include a reason string as to why the partition remain invalid. In addition, the cgroup-v2.rst documentation file is updated and a self test is added to verify the correctness the partition code. The code diff from v10 is listed below.

[PATCH net-next] selftests: forwarding: ethtool_extended_state: Convert to busywait

by Petr Machata

Currently, this script sets up the test scenario, which is supposed to end in an inability of the system to negotiate a link. It then waits for a bit, and verifies that the system can diagnose why the link was not established. The wait time for the scenario where different link speeds are forced on the two ends of a loopback cable, was set to 4 seconds, which exactly covered it. As of a recent mlxsw firmware update, this time gets longer, and this test starts failing. The time that selftests currently wait for links to be established is currently $WAIT_TIMEOUT, or 20 seconds. It seems reasonable that if this is the time necessary to establish and bring up a link, it should also be enough to determine that a link cannot be established and why. Therefore in this patch, convert the sleeps to busywaits, so that if a failure is established sooner (as is expected), the test runs quicker. And use $WAIT_TIMEOUT as the time to wait.

[net-next v3 0/4] seg6: add support for SRv6 Headend Reduced Encapsulation

by Andrea Mayer

This patchset adds support for SRv6 Headend behavior with Reduced Encapsulation. It introduces the H.Encaps.Red and H.L2Encaps.Red versions of the SRv6 H.Encaps and H.L2Encaps behaviors, according to RFC 8986 [1]. In details, the patchset is made of: - patch 1/4: add support for SRv6 H.Encaps.Red behavior; - Patch 2/4: add support for SRv6 H.L2Encaps.Red behavior; - patch 2/4: add selftest for SRv6 H.Encaps.Red behavior; - patch 3/4: add selftest for SRv6 H.L2Encaps.Red behavior. The corresponding iproute2 patch for supporting SRv6 H.Encaps.Red and H.L2Encaps.Red behaviors is provided in a separated patchset. [1] - https://datatracker.ietf.org/doc/html/rfc8986 v2 -> v3: - Keep SRH when HMAC TLV is present; - Split the support for H.Encaps.Red and H.L2Encaps.Red behaviors in two patches (respectively, patch 1/4 and patch 2/4); - Add selftests for SRv6 H.Encaps.Red and H.L2Encaps.Red. v1 -> v2: - Fixed sparse warnings; - memset now uses sizeof() instead of hardcoded value; - Removed EXPORT_SYMBOL_GPL. Andrea Mayer (4): seg6: add support for SRv6 H.Encaps.Red behavior seg6: add support for SRv6 H.L2Encaps.Red behavior selftests: seg6: add selftest for SRv6 H.Encaps.Red behavior selftests: seg6: add selftest for SRv6 H.L2Encaps.Red behavior include/uapi/linux/seg6_iptunnel.h | 2 + net/ipv6/seg6_iptunnel.c | 138 +++- .../net/srv6_hencap_red_l3vpn_test.sh | 742 ++++++++++++++++++ .../net/srv6_hl2encap_red_l2vpn_test.sh | 674 ++++++++++++++++ 4 files changed, 1554 insertions(+), 2 deletions(-) create mode 100755 tools/testing/selftests/net/srv6_hencap_red_l3vpn_test.sh create mode 100755 tools/testing/selftests/net/srv6_hl2encap_red_l2vpn_test.sh -- 2.20.1
