9b06d5b9 - selftests: net/{lib,openvswitch}: extend CFLAGS to keep options from environment

Thu, 23 Jan 2025 12:38:51 +0000

selftests: net/{lib,openvswitch}: extend CFLAGS to keep options from environmentPackage build environments like Fedora rpmbuild introduced hardeningoptions (e.g. -pie -Wl,-z,now) by passing a -spec option to CFLAGSand LDFLAGS.Some Makefiles currently override CFLAGS but not LDFLAGS, which leadsto a mismatch and build failure, for example: /usr/bin/ld: /tmp/ccd2apay.o: relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIE /usr/bin/ld: failed to set dynamic section sizes: bad value collect2: error: ld returned 1 exit status make[1]: *** [../../lib.mk:222: tools/testing/selftests/net/lib/csum] Error 1openvswitch/Makefile CFLAGS currently do not appear to be used, butfix it anyway for the case when new tests are introduced in future.Fixes: 1d0dc857b5d8 ("selftests: drv-net: add checksum tests")Signed-off-by: Jan Stancek Acked-by: Matthieu Baerts (NGI0) Reviewed-by: Hangbin Liu Link: https://patch.msgid.link/3d173603ee258f419d0403363765c9f9494ff79a.1737635092.git.jstancek@redhat.comSigned-off-by: Jakub Kicinski List of files: /linux-6.15/tools/testing/selftests/net/lib/Makefile

a6e263f1 - selftests: net: lib: Introduce deferred commands

Thu, 17 Oct 2024 09:45:43 +0000

selftests: net: lib: Introduce deferred commandsIn commit 8510801a9dbd ("selftests: drv-net: add ability to schedulecleanup 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 itharder to miss a cleanup, and make the whole cleanup business exceptionsafe. All these benefits are applicable to bash as well, exception safetycan be interpreted in terms of safety vs. a SIGINT.This patch therefore introduces a framework of several helpers that serveto 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 beused by all bash selftests, including those that do not currently uselib.sh. lib.sh however includes the file by default, because ideally alltests would use these helpers instead of hand-rolling their cleanups.Signed-off-by: Petr Machata Signed-off-by: Paolo Abeni List of files: /linux-6.15/tools/testing/selftests/net/lib/Makefile

1d0dc857 - selftests: drv-net: add checksum tests

Tue, 07 May 2024 15:40:58 +0000

selftests: drv-net: add checksum testsRun tools/testing/selftest/net/csum.c as part of drv-net.This binary covers multiple scenarios, based on arguments given,for both IPv4 and IPv6:- Accept UDP correct checksum- Detect UDP invalid checksum- Accept TCP correct checksum- Detect TCP invalid checksum- Transmit UDP: basic checksum offload- Transmit UDP: zero checksum conversionThe test direction is reversed between receive and transmit tests, sothat the NIC under test is always the local machine.In total this adds up to 12 testcases, with more to follow. Forconciseness, I replaced individual functions with a function factory.Also detect hardware offload feature availability using Ethtoolnetlink and skip tests when either feature is off. This need may becommon for offload feature tests and eventually deserving of a thinwrapper in lib.py.Missing are the PF_PACKET based send tests ('-P'). These usevirtio_net_hdr to program hardware checksum offload. Which requireslooking up the local MAC address and (harder) the MAC of the next hop.I'll have to give it some though how to do that robustly and wherethat code would belong.Tested: make -C tools/testing/selftests/ \ TARGETS="drivers/net drivers/net/hw" \ install INSTALL_PATH=/tmp/ksft cd /tmp/ksft sudo NETIF=ens4 REMOTE_TYPE=ssh \ REMOTE_ARGS="root@10.40.0.2" \ LOCAL_V4="10.40.0.1" \ REMOTE_V4="10.40.0.2" \ ./run_kselftest.sh -t drivers/net/hw:csum.pySigned-off-by: Willem de Bruijn Link: https://lore.kernel.org/r/20240507154216.501111-1-willemdebruijn.kernel@gmail.comSigned-off-by: Jakub Kicinski List of files: /linux-6.15/tools/testing/selftests/net/lib/Makefile

b86761ff - selftests: net: add scaffolding for Netlink tests in Python

Fri, 05 Apr 2024 02:45:22 +0000

selftests: net: add scaffolding for Netlink tests in PythonAdd glue code for accessing the YNL library which lives undertools/net and YAML spec files from under Documentation/.Automatically figure out if tests are run in tree or not.Since we'll want to use this library both from net anddrivers/net test targets make the library a target as well,and automatically include it when net or drivers/net areincluded. Making net/lib a target ensures that we end upwith only one copy of it, and saves us some path guessing.Add a tiny bit of formatting support to be able to output KTAPfrom the start.Reviewed-by: Petr Machata Signed-off-by: Jakub Kicinski Signed-off-by: David S.
