2020-02-26selftests: nft_concat_range: Add test for reported add/flush/add issueStefano Brivio1-4/+39
Add a specific test for the crash reported by Phil Sutter and addressed in the previous patch. The test cases that, in my intention, should have covered these cases, that is, the ones from the 'concurrency' section, don't run these sequences tightly enough and spectacularly failed to catch this. While at it, define a convenient way to add these kind of tests, by adding a "reported issues" test section. It's more convenient, for this particular test, to execute the set setup in its own function. However, future test cases like this one might need to call setup functions, and will typically need no tools other than nft, so allow for this in check_tools(). The original form of the reproducer used here was provided by Phil.

The commits introducing 'mlock-random-test'[1], 'map_fiex_noreplace'[2], and 'thuge-gen'[3] have not added those in the 'run_vmtests' script and thus the 'run_tests' command of kselftests doesn't run those.

Add append value operator "+=" support to bootconfig syntax. With this operator, user can add new value to the key as an entry of array instead of overwriting. For example, foo = bar ... foo += baz Then the key "foo" has "bar" and "baz" values as an array.

2020-02-21bootconfig: Prohibit re-defining value on same keyMasami Hiramatsu1-0/+6
Currently, bootconfig adds a new value on the existing key to the tail of an array. But this looks a bit confusing because an admin can easily rewrite the original value in the same config file. This rejects the following value re-definition. key = value1 ... key = value2 You should rewrite value1 to value2 in this case.

A value node can not co-exist with subkey node under some key node, e.g. key = value key.subkey = another-value This is not be allowed because bootconfig API is not designed to handle such case.

2020-02-20bootconfig: Add bootconfig magic word for indicating bootconfig explicitlyMasami Hiramatsu2-12/+33
Add bootconfig magic word to the end of bootconfig on initrd image for indicating explicitly the bootconfig is there. Also tools/bootconfig treats wrong size or wrong checksum or parse error as an error, because if there is a bootconfig magic word, there must be a bootconfig. The bootconfig magic word is "#BOOTCONFIG\n", 12 bytes word. Thus the block image of the initrd file with bootconfig is as follows. [Initrd][bootconfig][size][csum][#BOOTCONFIG\n] Link: http://lkml.kernel.org/r/158220112263.26565.3944814205960612841.stgit@devnote2 Suggested-by: Steven Rostedt <rostedt@goodmis.org> Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org> Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>

2020-02-20selftests: Install settings files to fix TIMEOUT failuresMichael Ellerman5-1/+9
Commit 852c8cbf34d3 ("selftests/kselftest/runner.sh: Add 45 second timeout per test") added a 45 second timeout for tests, and also added a way for tests to customise the timeout via a settings file. For example the ftrace tests take multiple minutes to run, so they were given longer in commit b43e78f65b1d ("tracing/selftests: Turn off timeout setting"). This works when the tests are run from the source tree. However if the tests are installed with "make -C tools/testing/selftests install", the settings files are not copied into the install directory. When the tests are then run from the install directory the longer timeouts are not applied and the tests timeout incorrectly. So add the settings files to TEST_FILES of the appropriate Makefiles to cause the settings files to be installed using the existing install logic.

Implemented small fix so that the script changes work directories to the root of the linux kernel source tree from which kunit.py is run. This enables the user to run kunit from any working directory. Originally considered using os.path.join but this is more error prone as we would have to find all file path usages and modify them accordingly. Using os.chdir ensures that the entire script is run within /linux.

2020-02-18libbpf: Sanitise internal map names so they are not rejected by the kernelToke Høiland-Jørgensen1-1/+7
The kernel only accepts map names with alphanumeric characters, underscores and periods in their name. However, the auto-generated internal map names used by libbpf takes their prefix from the user-supplied BPF object name, which has no such restriction. This can lead to "Invalid argument" errors when trying to load a BPF program using global variables. Fix this by sanitising the map names, replacing any non-allowed characters with underscores.

2020-02-16ipv6: Fix route replacement with dev-only routeBenjamin Poirier1-0/+6
After commit 27596472473a ("ipv6: fix ECMP route replacement") it is no longer possible to replace an ECMP-able route by a non ECMP-able route. For example, ip route add 2001:db8::1/128 via fe80::1 dev dummy0 ip route replace 2001:db8::1/128 dev dummy0 does not work as expected. Tweak the replacement logic so that point 3 in the log of the above commit becomes: 3. If the new route is not ECMP-able, and no matching non-ECMP-able route exists, replace matching ECMP-able route (if any) or add the new route. We can now summarize the entire replace semantics to: When doing a replace, prefer replacing a matching route of the same "ECMP-able-ness" as the replace argument. If there is no such candidate, fallback to the first route found.

For tc ip_proto filter, when we extract the flow via __skb_flow_dissect() without flag FLOW_DISSECTOR_F_STOP_AT_ENCAP, we will continue extract to the inner proto. So for GRE + ICMP messages, we should not track GRE proto, but inner ICMP proto. For test mirror_gre.sh, it may make user confused if we capture ICMP message on $h3(since the flow is GRE message). So I move the capture dev to h3-gt{4,6}, and only capture ICMP message.

2020-02-13wireguard: device: use icmp_ndo_send helperJason A. Donenfeld1-0/+11
Because wireguard is calling icmp from network device context, it should use the ndo helper so that the rate limiting applies correctly. This commit adds a small test to the wireguard test suite to ensure that the new functions continue doing the right thing in the context of wireguard. It does this by setting up a condition that will definately evoke an icmp error message from the driver, but along a nat'd path. Signed-off-by: Jason A.

More detail: https://www.gnu.org/software/make/manual/html_node/Implicit-Variables.html LDFLAGS Extra flags to give to compilers when they are supposed to invoke the linker, ‘ld’, such as -L. Libraries (-lfoo) should be added to the LDLIBS variable instead. LDLIBS Library flags or names given to compilers when they are supposed to invoke the linker, ‘ld’. LOADLIBES is a deprecated (but still supported) alternative to LDLIBS. Non-library linker flags, such as -L, should go in the LDFLAGS variable.

Pull tracing fixes from Steven Rostedt: "Various fixes: - Fix an uninitialized variable - Fix compile bug to bootconfig userspace tool (in tools directory) - Suppress some error messages of bootconfig userspace tool - Remove unneded CONFIG_LIBXBC from bootconfig - Allocate bootconfig xbc_nodes dynamically. To ease complaints about taking up static memory at boot up - Use of parse_args() to parse bootconfig instead of strstr() usage Prevents issues of double quotes containing the interested string - Fix missing ring_buffer_nest_end() on synthetic event error path - Return zero not -EINVAL on soft disabled synthetic event (soft disabling must be the same as hard disabling, which returns zero) - Consolidate synthetic event code (remove duplicate code)" * tag 'trace-v5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Consolidate trace() functions tracing: Don't return -EINVAL when tracing soft disabled synth events tracing: Add missing nest end to synth_event_trace_start() error case tools/bootconfig: Suppress non-error messages bootconfig: Allocate xbc_nodes array dynamically bootconfig: Use parse_args() to find bootconfig and '--' tracing/kprobe: Fix uninitialized variable bug bootconfig: Remove unneeded CONFIG_LIBXBC tools/bootconfig: Fix wrong __VA_ARGS__ usage
