2018-09-01selftests: pmtu: detect correct binary to ping ipv6 addressesSabrina Dubroca1-1/+4
Some systems don't have the ping6 binary anymore, and use ping for everything. Detect the absence of ping6 and try to use ping instead.

2018-09-01selftests: pmtu: maximum MTU for vti4 is 2^16-1-20Sabrina Dubroca1-1/+1
Since commit 82612de1c98e ("ip_tunnel: restore binding to ifaces with a large mtu"), the maximum MTU for vti4 is based on IP_MAX_MTU instead of the mysterious constant 0xFFF8. This makes this selftest fail.

2018-08-30tc-testing: add test-cases for numeric and invalid control actionPaolo Abeni1-0/+48
Only the police action allows us to specify an arbitrary numeric value for the control action. This change introduces an explicit test case for the above feature and then leverage it for testing the kernel behavior for invalid control actions (reject).

2018-08-22kvm: selftest: add dirty logging testPeter Xu4-0/+356
Test KVM dirty logging functionality. The test creates a standalone memory slot to test tracking the dirty pages since we can't really write to the default memory slot which still contains the guest ELF image. We have two threads running during the test: (1) the vcpu thread continuously dirties random guest pages by writting a iteration number to the first 8 bytes of the page (2) the host thread continuously fetches dirty logs for the testing memory region and verify each single bit of the dirty bitmap by checking against the values written onto the page Note that since the guest cannot calls the general userspace APIs like random(), it depends on the host to provide random numbers for the page indexes to dirty.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: - Restructure of lockdep and latency tracers This is the biggest change. Joel Fernandes restructured the hooks from irqs and preemption disabling and enabling. He got rid of a lot of the preprocessor #ifdef mess that they caused. He turned both lockdep and the latency tracers to use trace events inserted in the preempt/irqs disabling paths. But unfortunately, these started to cause issues in corner cases. Thus, parts of the code was reverted back to where lockdep and the latency tracers just get called directly (without using the trace events). But because the original change cleaned up the code very nicely we kept that, as well as the trace events for preempt and irqs disabling, but they are limited to not being called in NMIs. - Have trace events use SRCU for "rcu idle" calls. This was required for the preempt/irqs off trace events. But it also had to not allow them to be called in NMI context. Waiting till Paul makes an NMI safe SRCU API. - New notrace SRCU API to allow trace events to use SRCU. - Addition of mcount-nop option support - SPDX headers replacing GPL templates. - Various other fixes and clean ups. - Some fixes are marked for stable, but were not fully tested before the merge window opened. * tag 'trace-v4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (44 commits) tracing: Fix SPDX format headers to use C++ style comments tracing: Add SPDX License format tags to tracing files tracing: Add SPDX License format to bpf_trace.c blktrace: Add SPDX License format header s390/ftrace: Add -mfentry and -mnop-mcount support tracing: Add -mcount-nop option support tracing: Avoid calling cc-option -mrecord-mcount for every Makefile tracing: Handle CC_FLAGS_FTRACE more accurately Uprobe: Additional argument arch_uprobe to uprobe_write_opcode() Uprobes: Simplify uprobe_register() body tracepoints: Free early tracepoints after RCU is initialized uprobes: Use synchronize_rcu() not synchronize_sched() tracing: Fix synchronizing to event changes with tracepoint_synchronize_unregister() ftrace: Remove unused pointer ftrace_swapper_pid tracing: More reverting of "tracing: Centralize preemptirq tracepoints and unify their usage" tracing/irqsoff: Handle preempt_count for different configs tracing: Partial revert of "tracing: Centralize preemptirq tracepoints and unify their usage" tracing: irqsoff: Account for additional preempt_disable trace: Use rcu_dereference_raw for hooks from trace-event subsystem tracing/kprobes: Fix within_notrace_func() to check only notrace functions ...

The reason for this is in the python interface, that allows a script to pass arbitrary cpu number, which is then used to access struct perf_evlist::mmap array. That's obviously wrong and works only when if all cpus are available and fails if some cpu is missing, like in the example above. This patch makes pyrf_evlist__read_on_cpu() search the evlist's maps array for the proper map to access. It's linear search at the moment. Based on the way how is the read_on_cpu used, I don't think we need to be fast in here. But we could add some hash in the middle to make it fast/er. We don't allow python interface to set write_backward event attribute, so it's safe to check only evlist's mmaps.

2018-08-20perf tools: Add is_compressed callback to compressions arrayJiri Olsa4-3/+33
Add is_compressed callback to the compressions array, that returns 0 if the file is compressed or != 0 if not. The new callback is used to recognize the situation when we have a 'compressed' object, like: /lib/modules/.../drivers/net/ethernet/intel/igb/igb.ko.xz but we need to read its debug data from debuginfo files, which might not be compressed, like: /root/.debug/.build-id/d6/...c4b301f/debug So even for a 'compressed' object we read debug data from a plain uncompressed object. To keep this transparent, we detect this in decompress_kmodule() and return the file descriptor to the uncompressed file.

2018-08-20perf parser: Improve error message for PMU address filtersJack Henschel1-10/+10
This is the second version of a patch that improves the error message of the perf events parser when the PMU hardware does not support address filters. Previously, the perf returned the following error: $ perf record -e intel_pt// --filter 'filter sys_write' --filter option should follow a -e tracepoint or HW tracer option This implies there is some syntax error present in the command line, which is not true. Rather, notify the user that the CPU does not have support for this feature. For example, Intel chips based on the Broadwell micro-archticture have the Intel PT PMU, but do not support address filtering. Now, perf prints the following error message: $ perf record -e intel_pt// --filter 'filter sys_write' This CPU does not support address filtering Signed-off-by: Jack Henschel <jackdev@mailbox.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Acked-by: Jiri Olsa <jolsa@kernel.org> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/20180704121345.19025-1-jackdev@mailbox.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2018-08-20perf tools: Disable parallelism for 'make clean'Rasmus Villemoes1-2/+2
The Yocto build system does a 'make clean' when rebuilding due to changed dependencies, and that consistently fails for me (causing the whole BSP build to fail) with errors such as | find: '[...]/perf/1.0-r9/perf-1.0/plugin_mac80211.so': No such file or directory | find: '[...]/perf/1.0-r9/perf-1.0/plugin_mac80211.so': No such file or directory | find: find: '[...]/perf/1.0-r9/perf-1.0/libtraceevent.a''[...]/perf/1.0-r9/perf-1.0/libtraceevent.a': No such file or directory: No such file or directory | [...] | find: cannot delete '/mnt/xfs/devel/pil/yocto/tmp-glibc/work/wandboard-oe-linux-gnueabi/perf/1.0-r9/perf-1.0/util/.pstack.o.cmd': No such file or directory Apparently (despite the comment), 'make clean' ends up launching multiple sub-makes that all want to remove the same things - perhaps this only happens in combination with a O=... parameter. In any case, we don't lose much by explicitly disabling the parallelism for the clean target, and it makes automated builds much more reliable.
