2024-11-14selftest: extend test_rss_context_queue_reconfigure for action additionEdward Cree
The combination of ntuple action (ring_cookie) and RSS context can cause an ntuple rule to target a higher queue than appears in any RSS indirection table or directly in the ntuple rule, since the two numbers are added together. Verify the logic that prevents reducing the queue count in this case.

2024-11-14selftest: validate RSS+ntuple filters with nonzero ring_cookieEdward Cree
Test creates an ntuple filter with 'action 2' and an RSS context whose indirection table has entries 0 and 1. Resulting traffic should go to queues 2 and 3; verify that it never hits queues 0 and 1.

2024-11-14tools/net/ynl: add async notification handlingDonald Hunter
The notification handling in ynl is currently very simple, using sleep() to wait a period of time and then handling all the buffered messages in a single batch. This patch adds async notification handling so that messages can be processed as they are received. This makes it possible to use ynl as a library that supplies notifications in a timely manner. - Add poll_ntf() to be a generator that yields 1 notification at a time and blocks until a notification is available. - Add a --duration parameter to the CLI, with --sleep as an alias. ./tools/net/ynl/cli.py \ --spec <SPEC> --subscribe <TOPIC> [ --duration <SECS> ] The cli will report any notifications for duration seconds and then exit. If duration is not specified, then it will poll forever, until interrupted. Here is an example python snippet that shows how to use ynl as a library for receiving notifications: ynl = YnlFamily(f"{dir}/rt_route.yaml") ynl.ntf_subscribe('rtnlgrp-ipv4-route') for event in ynl.poll_ntf(): handle(event) Signed-off-by: Donald Hunter <donald.hunter@gmail.com> Link: https://patch.msgid.link/20241113090843.72917-3-donald.hunter@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Instead a new poll_ntf() will be added in a separate patch.

2024-11-12selftests: hugetlb_dio: fixup check for initial conditions to skip in the startDonet Tom
This test verifies that a hugepage, used as a user buffer for DIO operations, is correctly freed upon unmapping. To test this, we read the count of free hugepages before and after the mmap, DIO, and munmap operations, then check if the free hugepage count is the same. Reading free hugepages before the test was removed by commit 0268d4579901 ('selftests: hugetlb_dio: check for initial conditions to skip at the start'), causing the test to always fail. This patch adds back reading the free hugepages before starting the test. With this patch, the tests are now passing.

2024-11-11net: ipv4: Cache pmtu for all packet paths if multipath enabledVladimir Vdovin
Check number of paths by fib_info_num_path(), and update_or_create_fnhe() for every path. Problem is that pmtu is cached only for the oif that has received icmp message "need to frag", other oifs will still try to use "default" iface mtu. An example topology showing the problem: | host1 +---------+ | dummy0 | 10.179.20.18/32 mtu9000 +---------+ +-----------+----------------+ +---------+ +---------+ | ens17f0 | 10.179.2.141/31 | ens17f1 | 10.179.2.13/31 +---------+ +---------+ | (all here have mtu 9000) | +------+ +------+ | ro1 | 10.179.2.140/31 | ro2 | 10.179.2.12/31 +------+ +------+ | | ---------+------------+-------------------+------ | +-----+ | ro3 | 10.10.10.10 mtu1500 +-----+ | ======================================== some networks ======================================== | +-----+ | eth0| 10.10.30.30 mtu9000 +-----+ | host2 host1 have enabled multipath and sysctl net.ipv4.fib_multipath_hash_policy = 1: default proto static src 10.179.20.18 nexthop via 10.179.2.12 dev ens17f1 weight 1 nexthop via 10.179.2.140 dev ens17f0 weight 1 When host1 tries to do pmtud from 10.179.20.18/32 to host2, host1 receives at ens17f1 iface an icmp packet from ro3 that ro3 mtu=1500. And host1 caches it in nexthop exceptions cache. Problem is that it is cached only for the iface that has received icmp, and there is no way that ro3 will send icmp msg to host1 via another path. Host1 now have this routes to host2: ip r g 10.10.30.30 sport 30000 dport 443 10.10.30.30 via 10.179.2.12 dev ens17f1 src 10.179.20.18 uid 0 cache expires 521sec mtu 1500 ip r g 10.10.30.30 sport 30033 dport 443 10.10.30.30 via 10.179.2.140 dev ens17f0 src 10.179.20.18 uid 0 cache So when host1 tries again to reach host2 with mtu>1500, if packet flow is lucky enough to be hashed with oif=ens17f1 its ok, if oif=ens17f0 it blackholes and still gets icmp msgs from ro3 to ens17f1, until lucky day when ro3 will send it through another flow to ens17f0.

2024-11-11selftests: net: Add busy_poll_testJoe Damato
Add an epoll busy poll test using netdevsim. This test is comprised of: - busy_poller (via busy_poller.c) - busy_poll_test.sh which loads netdevsim, sets up network namespaces, and runs busy_poller to receive data and socat to send data. The selftest tests two different scenarios: - busy poll (the pre-existing version in the kernel) - busy poll with suspend enabled (what this series adds) The data transmit is a 1MiB temporary file generated from /dev/urandom and the test is considered passing if the md5sum of the input file to socat matches the md5sum of the output file from busy_poller. netdevsim was chosen instead of veth due to netdevsim's support for netdev-genl. For now, this test uses the functionality that netdevsim provides. In the future, perhaps netdevsim can be extended to emulate device IRQs to more thoroughly test all pre-existing kernel options (like defer_hard_irqs) and suspend.

2024-11-11ipv6: Fix soft lockups in fib6_select_path under high next hop churnOmid Ehtemam-Haghighi
Soft lockups have been observed on a cluster of Linux-based edge routers located in a highly dynamic environment. Using the `bird` service, these routers continuously update BGP-advertised routes due to frequently changing nexthop destinations, while also managing significant IPv6 traffic. The lockups occur during the traversal of the multipath circular linked-list in the `fib6_select_path` function, particularly while iterating through the siblings in the list. The issue typically arises when the nodes of the linked list are unexpectedly deleted concurrently on a different core—indicated by their 'next' and 'previous' elements pointing back to the node itself and their reference count dropping to zero. This results in an infinite loop, leading to a soft lockup that triggers a system panic via the watchdog timer. Apply RCU primitives in the problematic code sections to resolve the issue. Where necessary, update the references to fib6_siblings to annotate or use the RCU APIs. Include a test script that reproduces the issue. The script periodically updates the routing table while generating a heavy load of outgoing IPv6 traffic through multiple iperf3 clients. It consistently induces infinite soft lockups within a couple of minutes.

KVM x86 and selftests fixes for 6.12: - Increase the timeout for the memslot performance selftest to avoid false failures on arm64 and nested x86 platforms. - Fix a goof in the guest_memfd selftest where a for-loop initialized a bit mask to zero instead of BIT(0). - Disable strict aliasing when building KVM selftests to prevent the compiler from treating things like "u64 *" to "uint64_t *" cases as undefined behavior, which can lead to nasty, hard to debug failures. - Force -march=x86-64-v2 for KVM x86 selftests if and only if the uarch is supported by the compiler. - When emulating a guest TLB flush for a nested guest, flush vpid01, not vpid02, if L2 is active but VPID is disabled in vmcs12, i.e. if L2 and L1 are sharing VPID '0' (from L1's perspective). - Fix a bug in the SNP initialization flow where KVM would return '0' to userspace instead of -errno on failure.
