[PATCH net-next 00/13] mlxsw: Add resource scale tests

by Petr Machata

There are a number of tests that check features of the Linux networking stack. By running them on suitable interfaces, one can exercise the mlxsw offloading code. However none of these tests attempts to push mlxsw to the limits supported by the ASIC. As an additional wrinkle, the "limits supported by the ASIC" themselves may not be a set of fixed numbers, but rather depend on a profile that determines how the ASIC resources are allocated for different purposes. This patchset introduces several tests that verify capability of mlxsw to offload amounts of routes, flower rules, and mirroring sessions that match predicted ASIC capacity, at different configuration profiles. Additionally they verify that amounts exceeding the predicted capacity can *not* be offloaded. These are not generic tests, but ones that are tailored for mlxsw specifically. For that reason they are not added to net/forwarding selftests subdirectory, but rather to a newly-added drivers/net/mlxsw. Patches #1, #2 and #3 tweak the generic forwarding/lib.sh to support the new additions. In patches #4 and #5, new libraries for interfacing with devlink are introduced, first a generic one, then a Spectrum-specific one. In patch #6, a devlink resource test is introduced. Patches #7 and #8, #9 and #10, and #11 and #12 introduce three scale tests: router, flower and mirror-to-gretap. The first of each pair of patches introduces a generic portion of the test (mlxsw-specific), the second introduces a Spectrum-specific wrapper. Patch #13 then introduces a scale test driver that runs (possibly a subset of) the tests introduced by patches from previous paragraph.

[PATCH net-next 0/4] Fixes for running mirror-to-gretap tests on veth

by Petr Machata

The forwarding selftests infrastructure makes it possible to run the individual tests on a purely software netdevices. Names of interfaces to run the test with can be passed as command line arguments to a test. lib.sh then creates veth pairs backing the interfaces if none exist in the system. However, the tests need to recognize that they might be run on a soft device. Many mirror-to-gretap tests are buggy in this regard. This patch set aims to fix the problems in running mirror-to-gretap tests on veth devices. In patch #1, a service function is split out of setup_wait(). In patch #2, installing a trap is made optional. In patch #3, tc filters in several tests are tweaked to work with veth. In patch #4, the logic for waiting for neighbor is fixed for veth.

[PATCH v9 0/7] Centralize and unify usage of preempt/irq tracepoints

by Joel Fernandes

From: "Joel Fernandes (Google)" <joel(a)joelfernandes.org> This is a posting of v9 preempt/irq tracepoint clean up series rebased onto v4.18-rc2. No changes in the series, just a rebase + repost. All patches have a Reviewed-by tags now from reviewers. This series has been well tested and is a simplification/refactoring of existing code, along with giving a speed-up for tracepoints using the rcu-idle API. With this our users will find it easier to use tools depending on existing preempt tracepoints since it simplifies the configuration for them. Future enhancements/fixes I am developing for preempt-off tracer will depend on these patches, so I suggest prioritizing these well reviewed and tested patches for that reason as well. Introduction to the series: The preempt/irq tracepoints exist but not everything in the kernel is using it whenever they need to be notified that a preempt disable/enable or an irq disable/enable has occurred. This makes things not work simultaneously (for example, only either lockdep or irqsoff trace-events can be used at a time). This is particularly painful to deal with, since turning on lockdep breaks tracers that install probes on IRQ events, such as the BCC atomic critical section tracer [1]. This constraint also makes it impossible to use synthetic events to trace irqsoff sections with lockdep simulataneously turned on. This series solves that, and also results in a nice clean up of relevant parts of the kernel. Several ifdefs are simpler, and the design is more unified and better. Also as a result of this, we also speeded performance all rcuidle tracepoints since their handling is simpler. [1] https://github.com/iovisor/bcc/blob/master/tools/criticalstat_example.txt v8->v9: - Small style changes to tracepoint code (Mathieu) - Minor style fix to use PTR_ERR_OR_ZERO (0-day bot) - Minor fix to test_atomic_sections to use unsigned long. - Added Namhyung's, Mathieu's Reviewed-by to some patches. - Added Acks from Matsami v7->v8: - Refactored irqsoff tracer probe defines (Namhyung) v6->v7: - Added a module to simulate an atomic section, a kselftest to load and and trigger it which verifies the preempt-tracer and this series. - Fixed a new warning after I rebased in early boot, this is because early_boot_irqs_disabled was set too early, I moved it after the lockdep initialization. - added back the softirq fix since it appears it wasn't picked up. - Ran Ingo's locking API selftest suite which are passing with this series. - Mathieu suggested ifdef'ing the tracepoint_synchronize_unregister function incase tracepoints aren't enabled, did that.

Hi Thomas- Something went wrong when you applied the patch mentioned above. The original patch is here: https://lore.kernel.org/lkml/d4c4d9985fbe64f8c9e19291886453914b48caee.15239… but somehow it got applied with huge offset -- the same exact change was made, but it was made to the entirely wrong function! I'm a little nervous about sending a fixup patch because there are three copies of that code in the file, and I don't want to just move the problem around. What's the right thing to do here? Clearly this needs to get fixed somehow, and the fix should go to -stable. --Andy -- To unsubscribe from this list: send the line "unsubscribe linux-kselftest" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

[PATCH net-next 0/6] Multipath tests for tunnel devices

by Petr Machata

This patchset adds a test for ECMP and weighted ECMP between two GRE tunnels. In patches #1 and #2, the function multipath_eval() is first moved from router_multipath.sh to lib.sh for ease of reuse, and then fixed up. In patch #3, the function tc_rule_stats_get() is parameterized to be useful for egress rules as well. In patch #4, a new function __simple_if_init() is extracted from simple_if_init(). This covers the logic that needs to be done for the usual interface: VRF migration, upping and installation of IP addresses. Patch #5 then adds the test itself. Additionally in patch #6, a requirement to add diagrams to selftests is documented.
