2020-11-04selftests: mptcp: add ADD_ADDR timeout test caseGeliang Tang2-24/+80
This patch added the test case for retransmitting ADD_ADDR when timeout occurs. It set NS1's add_addr_timeout to 1 second, and drop NS2's ADD_ADDR echo packets. Here we need to slow down the transfer process of all data to let the ADD_ADDR suboptions can be retransmitted three times. So we added a new parameter "speed" for do_transfer, it can be set with fast or slow. We also added three new optional parameters for run_tests, and dropped run_remove_tests function. Since we added the netfilter rules in this test case, we need to update the "config" file.

2020-11-03tools kvm headers: Update KVM headers from the kernel sourcesArnaldo Carvalho de Melo6-1/+82
Some should cause changes in tooling, like the one adding LAST_EXCP, but the way it is structured end up not making that happen. The new SVM_EXIT_INVPCID should get used by arch/x86/util/kvm-stat.c, in the svm_exit_reasons table. The tools/perf/trace/beauty part has scripts to catch changes and automagically create tables, like tools/perf/trace/beauty/kvm_ioctl.sh, but changes are needed to make tools/perf/arch/x86/util/kvm-stat.c catch those automatically.

2020-11-03perf tools: Remove broken __no_tail_call attributePeter Zijlstra3-20/+5
The GCC specific __attribute__((optimize)) attribute does not what is commonly expected and is explicitly recommended against using in production code by the GCC people. Unlike what is often expected, it doesn't add to the optimization flags, but it fully replaces them, loosing any and all optimization flags provided by the compiler commandline. The only guaranteed upon means of inhibiting tail-calls is by placing a volatile asm with side-effects after the call such that the tail-call simply cannot be done. Given the original commit wasn't specific on which calls were the problem, this removal might re-introduce the problem, which can then be re-analyzed and cured properly.

2020-11-03perf vendor events: Fix DRAM_BW_Use 0 issue for CLX/SKXJin Yao2-2/+2
Ian reports an issue that the metric DRAM_BW_Use often remains 0. The metric expression for DRAM_BW_Use on CLX/SKX: "( 64 * ( uncore_imc@cas_count_read@ + uncore_imc@cas_count_write@ ) / 1000000000 ) / duration_time" The counts of uncore_imc/cas_count_read/ and uncore_imc/cas_count_write/ are scaled up by 64, that is to turn a count of cache lines into bytes, the count is then divided by 1000000000 to give GB. However, the counts of uncore_imc/cas_count_read/ and uncore_imc/cas_count_write/ have been scaled yet. The scale values are from sysfs, such as /sys/devices/uncore_imc_0/events/cas_count_read.scale. It's 6.103515625e-5 (64 / 1024.0 / 1024.0). So if we use original metric expression, the result is not correct. But the difficulty is, for SKL client, the counts are not scaled. The metric expression for DRAM_BW_Use on SKL: "64 * ( arb@event\\=0x81\\,umask\\=0x1@ + arb@event\\=0x84\\,umask\\=0x1@ ) / 1000000 / duration_time / 1000" root@kbl-ppc:~# perf stat -M DRAM_BW_Use -a -- sleep 1 Performance counter stats for 'system wide': 190 arb/event=0x84,umask=0x1/ # 1.86 DRAM_BW_Use 29,093,178 arb/event=0x81,umask=0x1/ 1,000,703,287 ns duration_time 1.000703287 seconds time elapsed The result is expected. So the easy way is just change the metric expression for CLX/SKX. This patch changes the metric expression to: "( ( ( uncore_imc@cas_count_read@ + uncore_imc@cas_count_write@ ) * 1048576 ) / 1000000000 ) / duration_time" 1048576 = 1024 * 1024.

2020-11-03perf tools: Remove LTO compiler options when building perl supportJustin M. Forbes1-0/+1
To avoid breaking the build by mixing files compiled with things coming from distro specific compiler options for perl with the rest of perf, i.e. to avoid this: `.gnu.debuglto_.debug_macro' referenced in section `.gnu.debuglto_.debug_macro' of /tmp/build/perf/util/scripting-engines/perf-in.o: defined in discarded section `.gnu.debuglto_.debug_macro[wm4.stdcpredef.h.19.8dc41bed5d9037ff9622e015fb5f0ce3]' of /tmp/build/perf/util/scripting-engines/perf-in.o Noticed on Fedora 33.

2020-11-02selftests: add test script for bareudp tunnelsGuillaume Nault3-0/+546
Test different encapsulation modes of the bareudp module: * Unicast MPLS, * IPv4 only, * IPv4 in multiproto mode (that is, IPv4 and IPv6), * IPv6. Each mode is tested with both an IPv4 and an IPv6 underlay. v2: * Add build dependencies in config file (Willem de Bruijn). * The MPLS test now uses its own IP addresses. This minimises the amount of cleanup between tests and simplifies the script. * Verify that iproute2 supports bareudp tunnels before running the script (and other minor usability improvements).

2020-11-02selftests/net: timestamping: add ptp v2 supportGrygorii Strashko1-13/+34
The timestamping tool is supporting now only PTPv1 (IEEE-1588 2002) while modern HW often supports also/only PTPv2. Hence timestamping tool is still useful for sanity testing of PTP drivers HW timestamping capabilities it's reasonable to upstate it to support PTPv2. This patch adds corresponding support which can be enabled by using new parameter "PTPV2".
