| | | | * | | | | | | | | | | | | | | | | torture: Save "make allmodconfig" .config filePaul E. McKenney2022-04-201-0/+1

No harm done in that it is just passed as an argument to the /init program in initrd, but this commit nevertheless removes it. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>

Although this allows much more flexibility from a single kernel binary, it means that the current rcutorture scenarios won't find build errors that happen only when preemption is fully disabled at build time. This commit therefore adds CONFIG_PREEMPT_DYNAMIC=n to several scenarios, and while in the area switches one from CONFIG_PREEMPT_NONE=y to CONFIG_PREEMPT_VOLUNTARY=y to add coverage of this Kconfig option.

The processors are numbered that way on POWER8. $ sudo ppc64_cpu --smt=8 $ lscpu | grep '^NUMA node' NUMA node(s): 2 NUMA node0 CPU(s): 0-79 NUMA node8 CPU(s): 80-159 This causes the heuristic to detect the number threads per core, looking for the number after the first comma, to fail, and QEMU aborts because of invalid arguments. $ lscpu | grep '^NUMA node0' | sed -e 's/^[^,-]*(,|\-)\([0-9]*\),.*$/\1/' NUMA node0 CPU(s): 0-79 But the lscpu command shows the number of threads per core: $ sudo ppc64_cpu --smt=8 $ lscpu | grep 'Thread(s) per core' Thread(s) per core: 8 $ sudo ppc64_cpu --smt=off $ lscpu | grep 'Thread(s) per core' Thread(s) per core: 1 This commit therefore directly uses that value and replaces use of grep with "sed -n" and its "p" command.

The changes required are to the appropriate Makefile and Kconfig file, plus a directory whose name begins with "X" must be added to the rcutorture/configs file. This new directory's name can then be passed in via the kvm.sh script's --torture parameter. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>

As its name suggests, it controls the frequency of statistics printing, but it also controls the rcu_torture_writer() stall timeout. The current setting of 15 seconds works surprisingly well. However, given that the RCU tasks stall-warning timeout is ten -minutes-, 15 seconds is too short for TASKS02, which runs a non-preemptible kernel on a single CPU. This commit therefore adds checks for per-scenario specification of the rcutorture.stat_interval module parameter. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>

This unnecessarily increases kernel size. This commit therefore decouples the presence of rcutorture from the presence of RCU Tasks Trace. However, there is a need to select CONFIG_TASKS_TRACE_RCU for testing purposes. Except that casual users must not be bothered with questions -- for them, this needs to be fully automated. There is thus a CONFIG_FORCE_TASKS_TRACE_RCU that selects CONFIG_TASKS_TRACE_RCU, is user-selectable, but which depends on CONFIG_RCU_EXPERT.

Because CONFIG_TASKS_RCU=y is needed only in kernels doing tracing of one form or another, this commit moves from TASKS_RCU deciding when it should be enabled to the tracing Kconfig options explicitly selecting it. This allows building preemptible kernels without TASKS_RCU, if desired. This commit also updates the SRCU-N and TREE09 rcutorture scenarios in order to avoid Kconfig errors that would otherwise result from CONFIG_TASKS_RCU being selected without its CONFIG_RCU_EXPERT dependency being met.

When building the selftests using its own Makefile directly, such as via the following command run in a kernel tree: One receives an error such as the following: make: Entering directory '/root/linux/tools/testing/selftests' make --no-builtin-rules ARCH=x86 -C ../../.. headers_install make[1]: Entering directory '/root/linux' INSTALL ./usr/include make[1]: Leaving directory '/root/linux' make[1]: Entering directory '/root/linux/tools/testing/selftests/vm' make[1]: *** No rule to make target 'vm.c', needed by '/root/linux/tools/testing/selftests/vm/vm_64'.

By default, ping_group_range is set to '1 0', which forces ping to use an ip raw socket. Let's replay the ping tests by allowing 'ping' to use the ip icmp socket. After the previous patch, ipv4 tests results are the same with both kinds of socket. For ipv6, there are a lot a new failures (the previous patch fixes only two cases).

The point is that hardware can't offload that police action, so not specifying "conform-exceed" was always wrong, even though the command used to work in hardware (but not in software) until the kernel started adding validation for it. Fix the command used by the selftest by making the policer drop on exceed, and pass the packet to the next action (goto) on conform.

Since riscv doesn't have a second serial port in its device description, we have to use virtio's vport. This is actually the same situation on ARM, but we were previously hacking QEMU up to work around this, which required a custom QEMU. Instead just do the vport trick on ARM too.

This means that by the time the PVID is changed, br1 is already operational and configured with an IPv6 link-local address. When the test is run with netdevs registered by mlxsw, changing the PVID is vetoed, as changing the VID associated with an existing L3 interface is forbidden. This restriction is similar to the 8021q driver's restriction of changing the VID of an existing interface. Fix this by taking br1 down and bringing it back up when it is fully configured. With this fix, the test reliably passes on top of both the SW and HW data paths (emulated or not).

This means that trying to read from stdin now throws SIGTTIN when stdin is a TTY, which breaks some seccomp selftests that try to use read(0, NULL, 0) as a dummy syscall. The simplest way to fix that is probably to just use -1 instead of 0 as the dummy read()'s FD.
