2023-02-13selftests: find echo binary to use -ne optionsGuillaume Tucker
Find the actual echo binary using $(which echo) and use it for formatted output with -ne. On some systems, the default echo command doesn't handle the -e option and the output looks like this (arm64 build): -ne Emit Tests for alsa -ne Emit Tests for amd-pstate -ne Emit Tests for arm64 This is for example the case with the KernelCI Docker images e.g. kernelci/gcc-10:x86-kselftest-kernelci. With the actual echo binary (e.g. in /bin/echo), the output is formatted as expected (x86 build this time): Emit Tests for alsa Emit Tests for amd-pstate Skipping non-existent dir: arm64 Only the install target is using "echo -ne" so keep the $ECHO variable local to it.

Use $(KHDR_INCLUDES) as lookup path for installed kernel headers rather than using kernel headers in include/uapi from the source kernel tree kernel headers. Remove bogus ../../../../include/ from the search path, because kernel source headers are not needed by those user-space selftests, and it causes issues because -I paths are searched before -isystem paths, and conflicts for files appearing both in kernel sources and in uapi headers with incompatible semantics (e.g. types.h).

2023-02-10selftests: forwarding: Add MDB dump test casesIdo Schimmel
The kernel maintains three markers for the MDB dump: 1. The last bridge device from which the MDB was dumped. 2. The last MDB entry from which the MDB was dumped. 3. The last port-group entry that was dumped. Add test cases for large scale MDB dump to make sure that all the configured entries are dumped and that the markers are used correctly. Specifically, create 2 bridges with 32 ports and add 256 MDB entries in which all the ports are member of. Test that each bridge reports 8192 (256 * 32) permanent entries. Do that with IPv4, IPv6 and L2 MDB entries. On my system, MDB dump of the above is contained in about 50 netlink messages.

2023-02-10selftests/bpf: Split SAN_CFLAGS and SAN_LDFLAGSIlya Leoshkevich
Memory Sanitizer requires passing different options to CFLAGS and LDFLAGS: besides the mandatory -fsanitize=memory, one needs to pass header and library paths, and passing -L to a compilation step triggers -Wunused-command-line-argument. So introduce a separate variable for linker flags. Use $(SAN_CFLAGS) as a default in order to avoid complicating the ASan usage.

2023-02-10selftests/bpf: Quote host toolsIlya Leoshkevich
Using HOSTCC="ccache clang" breaks building the tests, since, when it's forwarded to e.g. bpftool, the child make sees HOSTCC=ccache and "clang" is considered a target. Fix by quoting it, and also HOSTLD and HOSTAR for consistency.

2023-02-09selftests: fib_rule_tests: Test UDP and TCP connections with DSCP rules.Guillaume Nault
Add the fib_rule6_send and fib_rule4_send tests to verify that DSCP values are properly taken into account when UDP or TCP sockets try to connect(). Tests are done with nettest, which needs a new option to specify the DS Field value of the socket being tested. This new option is named '-Q', in reference to the similar option used by ping.

2023-02-09perf stat: Avoid merging/aggregating metric counts twiceIan Rogers
The added perf_stat_merge_counters combines uncore counters. When metrics are enabled, the counts are merged into a metric_leader via the stat-shadow saved_value logic. As the leader now is passed an aggregated count, it leads to all counters being added together twice and counts appearing approximately doubled in metrics. This change disables the saved_value merging of counts for evsels that are merged. It is recommended that later changes remove the saved_value entirely as the two layers of aggregation in the code is confusing.

Thorsten reported build issue with command line that defined extra HOSTCFLAGS that were not passed into 'prepare' targets, but were used to build resolve_btfids objects. This results in build fail when these objects are linked together: /usr/bin/ld: /build.../tools/bpf/resolve_btfids//libbpf/libbpf.a(libbpf-in.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE \ object; recompile with -fPIE Fixing this by passing HOSTCFLAGS in EXTRA_CFLAGS as part of HOST_OVERRIDES variable for prepare targets.
