In the next patch the hard-coded queue numbers are gonna be removed. So introduce some initial support for ethtool YNL and use it to enable header split. Also, tcp-data-split requires latest ethtool which is unlikely to be present in the distros right now. (ideally, we should not shell out to ethtool at all).

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.

2024-10-30tests: hsr: Increase timeout to 50 secondsYunshui Jiang
The HSR test, hsr_ping.sh, actually needs 7 min to run. Around 375s to be exact, and even more on a debug kernel or kernel with other network security limits. The timeout setting for the kselftest is currently 45 seconds, which is way too short to integrate hsr tests to run_kselftest infrastructure. However, timeout of hundreds of seconds is quite a long time, especially in a CI/CD environment. It seems that we need accelerate the test and balance with timeout setting. The most time-consuming func is do_ping_long, where ping command sends 10 packages to the given address. The default interval between two ping packages is 1s according to the ping Mannual. There isn't any operation between pings thus we could pass -i 0.1 to ping to make it 10 times faster. While even with this short interval, the test still need about 46.4 seconds to finish because of the two HSR interfaces, each of which is tested by calling do_ping func 12 times and do_ping_long func 19 times and sleep for 3s. So, an explicit setting is also needed to slightly increase the timeout. And to leave us some slack, use 50 as default timeout.

2024-10-29selftests: netfilter: nft_flowtable.sh: make first pass deterministicFlorian Westphal
The CI occasionaly encounters a failing test run. Example: # PASS: ipsec tunnel mode for ns1/ns2 # re-run with random mtus: -o 10966 -l 19499 -r 31322 # PASS: flow offloaded for ns1/ns2 [..] # FAIL: ipsec tunnel ... counter 1157059 exceeds expected value 878489 This script will re-exec itself, on the second run, random MTUs are chosen for the involved links. This is done so we can cover different combinations (large mtu on client, small on server, link has lowest mtu, etc). Furthermore, file size is random, even for the first run. Rework this script and always use the same file size on initial run so that at least the first round can be expected to have reproducible behavior. Second round will use random mtu/filesize. Raise the failure limit to that of the file size, this should avoid all errneous test errors. Currently, first fin will remove the offload, so if one peer is already closing remaining data is handled by classic path, which result in larger-than-expected counter and a test failure. Given packet path also counts tcp/ip headers, in case offload is completely broken this test will still fail (as expected). The test counter limit could be made more strict again in the future once flowtable can keep a connection in offloaded state until FINs in both directions were seen.

Instead of having a suite of dedicated cleanup functions, use the defer framework to schedule cleanups right as their setup functions are run.

2024-10-22selftests: forwarding: Add a fallback cleanup()Petr Machata
Consistent use of defers obviates the need for a separate test-specific cleanup function -- everything is just taken care of in defers. So in this patch, introduce a cleanup() helper in the forwarding lib.sh, which calls just pre_cleanup() and defer_scopes_cleanup(). Selftests are obviously still free to override the function. Since pre_cleanup() is too entangled with forwarding-specific minutia, the function cannot currently be in net/lib.sh.

2024-10-22selftests: net: lib: Introduce deferred commandsPetr Machata
In commit 8510801a9dbd ("selftests: drv-net: add ability to schedule cleanup with defer()"), a defer helper was added to Python selftests. The idea is to keep cleanup commands close to their dirtying counterparts, thereby making it more transparent what is cleaning up what, making it harder to miss a cleanup, and make the whole cleanup business exception safe. All these benefits are applicable to bash as well, exception safety can be interpreted in terms of safety vs. a SIGINT. This patch therefore introduces a framework of several helpers that serve to schedule cleanups in bash selftests: - defer_scope_push(), defer_scope_pop(): Deferred statements can be batched together in scopes. When a scope is popped, the deferred commands scheduled in that scope are executed in the order opposite to order of their scheduling. - defer(): Schedules a defer to the most recently pushed scope (or the default scope if none was pushed.) - defer_prio(): Schedules a defer on the priority track. The priority defer queue is run before the default defer queue when scope is popped. The issue that this is addressing is specifically the one of restoring devlink shared buffer threshold type. When setting up static thresholds, one has to first change the threshold type to static, then override the individual thresholds. When cleaning up, it would be natural to reset the threshold values first, then change the threshold type. But the values that are valid for dynamic thresholds are generally invalid for static thresholds and vice versa. Attempts to restore the values first would be bounced. Thus one has to first reset the threshold type, then adjust the thresholds. (You could argue that the shared buffer threshold type API is broken and you would be right, but here we are.) This cannot be solved by pure defers easily. I considered making it possible to disable an existing defer, so that one could then schedule a new defer and disable the original. But this forward-shifting of the defer job would have to take place after every threshold-adjusting command, which would make it very awkward to schedule these jobs. - defer_scopes_cleanup(): Pops any unpopped scopes, including the default one. The selftests that use defer should run this in their exit trap. This is important to get cleanups of interrupted scripts. - in_defer_scope(): Sometimes a function would like to introduce a new defer scope, then run whatever it is that it wants to run, and then pop the scope to run the deferred cleanups. The helper in_defer_scope() can be used to run another command within such environment, such that any scheduled defers run after the command finishes. The framework is added as a separate file lib/sh/defer.sh so that it can be used by all bash selftests, including those that do not currently use lib.sh. lib.sh however includes the file by default, because ideally all tests would use these helpers instead of hand-rolling their cleanups.
