2020-02-21selftests/vm: add missed tests in run_vmtestsSeongJae Park1-0/+33
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. This commit adds those in the script. 'gup_benchmark' and 'transhuge-stress' are also not included in the 'run_vmtests', but this commit does not add those because those are for performance measurement rather than pass/fail tests.

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.

2020-02-16selftests: forwarding: use proto icmp for {gretap, ip6gretap}_mac testingHangbin Liu1-12/+13
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.

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.

2020-02-10selftests: fix too long argumentJiri Benc1-10/+13
With some shells, the command construed for install of bpf selftests becomes too large due to long list of files: make[1]: execvp: /bin/sh: Argument list too long make[1]: *** [../lib.mk:73: install] Error 127 Currently, each of the file lists is replicated three times in the command: in the shell 'if' condition, in the 'echo' and in the 'rsync'. Reduce that by one instance by using make conditionals and separate the echo and rsync into two shell commands. (One would be inclined to just remove the '@' at the beginning of the rsync command and let 'make' echo it by itself; unfortunately, it appears that the '@' in the front of mkdir silences output also for the following commands.) Also, separate handling of each of the lists to its own shell command. The semantics of the makefile is unchanged before and after the patch. The ability of individual test directories to override INSTALL_RULE is retained.

2020-02-10selftests: allow detection of build failuresJiri Benc1-2/+10
Commit 5f70bde26a48 ("selftests: fix build behaviour on targets' failures") added a logic to track failure of builds of individual targets. However, it does exactly the opposite of what a distro kernel needs: we create a RPM package with a selected set of selftests and we need the build to fail if build of any of the targets fail. Both use cases are valid. A distribution kernel is in control of what is included in the kernel and what is being built; any error needs to be flagged and acted upon. A CI system that tries to build as many tests as possible on the best effort basis is not really interested in a failure here and there. Support both use cases by introducing a FORCE_TARGETS variable. It is switched off by default to make life for CI systems easier, distributions can easily switch it on while building their packages.

While running the ftracetests, the pid filter test failed because the instance "foo" existed, and it was using it to rerun the test under a instance named foo. The collision caused the test to fail as the mkdir failed as the name already existed. As of commit b5b77be812de7 ("selftests: ftrace: Allow some tests to be run in a tracing instance") all a selftest needs to do to be tested in an instance is to set the "instance" flag. There's no reason a selftest needs to create an instance to run its test in an instance directly.

2020-02-07selftests/bpf: Test freeing sockmap/sockhash with a socket in itJakub Sitnicki1-0/+74
Commit 7e81a3530206 ("bpf: Sockmap, ensure sock lock held during tear down") introduced sleeping issues inside RCU critical sections and while holding a spinlock on sockmap/sockhash tear-down. There has to be at least one socket in the map for the problem to surface. This adds a test that triggers the warnings for broken locking rules. Not a fix per se, but rather tooling to verify the accompanying fixes. Run on a VM with 1 vCPU to reproduce the warnings.

Turns out that when we accept a new subflow, the newly created inet_sk(tcp_sk)->pinet6 points at the ipv6_pinfo structure of the listener socket.

2020-02-02selftests: net: Add FIN_ACK processing order related latency spike testSeongJae Park4-0/+189
This commit adds a test for FIN_ACK process races related reconnection latency spike issues. The issue has described and solved by the previous commit ("tcp: Reduce SYN resend delay if a suspicous ACK is received"). The test program is configured with a server and a client process. The server creates and binds a socket to a port that dynamically allocated, listen on it, and start a infinite loop. Inside the loop, it accepts connection, reads 4 bytes from the socket, and closes the connection. The client is constructed as an infinite loop. Inside the loop, it creates a socket with LINGER and NODELAY option, connect to the server, send 4 bytes data, try read some data from server. After the read() returns, it measure the latency from the beginning of this loop to this point and if the latency is larger than 1 second (spike), print a message.

Fix the gup benchmark flags to use the symbolic FOLL_WRITE, instead of a hard-coded "1" value. Also, clean up the filtering of gup flags a little, by just doing it once before issuing any of the get_user_pages*() calls. This makes it harder to overlook, instead of having little "gup_flags & 1" phrases in the function calls.
