2021-12-25selftests: mptcp: Remove the deprecated config NFT_COUNTERMa Xinjian
NFT_COUNTER was removed since 390ad4295aa ("netfilter: nf_tables: make counter support built-in") LKP/0Day will check if all configs listing under selftests are able to be enabled properly. For the missing configs, it will report something like: LKP WARN miss config CONFIG_NFT_COUNTER= of net/mptcp/config - it's not reasonable to keep the deprecated configs. - configs under kselftests are recommended by corresponding tests. So if some configs are missing, it will impact the testing results Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Ma Xinjian <xinjianx.ma@intel.com> Signed-off-by: David S.

2021-11-01selftests: mptcp: more stable simult_flows testsPaolo Abeni
Currently the simult_flows.sh self-tests are not very stable, especially when running on slow VMs. The tests measure runtime for transfers on multiple subflows and check that the time is near the theoretical maximum. The current test infra introduces a bit of jitter in test runtime, due to multiple explicit delays. Additionally the runtime is measured by the shell script wrapper. On a slow VM, the script overhead is measurable and subject to relevant jitter. One solution to make the test more stable would be adding more slack to the expected time; that could possibly hide real regressions. Instead move the measurement inside the command doing the transfer, and drop most unneeded sleeps.

2021-10-16mptcp: increase default max additional subflows to 2Paolo Abeni
The current default does not allowing additional subflows, mostly as a safety restriction to avoid uncontrolled resource consumption on busy servers. Still the system admin and/or the application have to opt-in to MPTCP explicitly. After that, they need to change (increase) the default maximum number of additional subflows. Let set that to reasonable default, and make end-users life easier. Additionally we need to update some self-tests accordingly.

2021-09-18selftests: mptcp: add mptcp getsockopt test casesFlorian Westphal
Add a test program that retrieves the three info types: 1. mptcp meta information 2. tcp info for subflow 3. subflow endpoint addresses For all three rudimentary checks are added. 1. Meta information checks that the logical mptcp sequence numbers advance as expected, based on the bytes read (init seq + bytes_received/sent) and the connection state (after close, we should exect 1 extra byte due to FIN). 2. TCP info checks the number of bytes sent/received vs. sums of read/write syscall return values. 3. Subflow endpoint addresses are checked vs. getsockname/getpeername result. Tests for forward compatibility (0-initialisation of output-only fields in mptcp_subflow_data structure) are added as well.

2021-04-02selftests: mptcp: launch mptcp_connect with timeoutMatthieu Baerts
'mptcp_connect' already has a timeout for poll() but in some cases, it is not enough. With "timeout" tool, we will force the command to fail if it doesn't finish on time. Thanks to that, the script will continue and display details about the current state before marking the test as failed. Displaying this state is very important to be able to understand the issue. Best to have our CI reporting the issue than just "the test hanged". Note that in mptcp_connect.sh, we were using a long timeout to validate the fact we cannot create a socket if a sysctl is set. We don't need this timeout. In diag.sh, we want to send signals to mptcp_connect instances that have been started in the netns. But we cannot send this signal to 'timeout' otherwise that will stop the timeout and messages telling us SIGUSR1 has been received will be printed. Instead of trying to find the right PID and storing them in an array, we can simply use the output of 'ip netns pids' which is all the PIDs we want to send signal to.

2021-03-30selftests: mptcp: avoid calling pm_nl_ctl with bad IDsMatthieu Baerts
IDs are supposed to be between 0 and 255. In pm_nl_ctl, for both the 'add' and 'get' instruction, the ID is casted in a u_int8_t. So if we give 256, we will delete ID 0. Obviously, the goal is not to delete this ID by giving 256. We could modify pm_nl_ctl and stop if the ID is negative or higher than 255 but probably better not to increase the number of lines for such things in this tool which is only used in selftests. Instead, we use it within the limits. This modification also means that we will no longer add a new ID for the 2nd entry. That's why we removed an expected entry from the dump and introduced with commit dc8eb10e95a8 ("selftests: mptcp: add testcases for setting the address ID"). So now we delete ID 9 like before and we add entries for IDs 10 to 255 that are deleted just after. Note that this could be seen as a fix but it was not really an issue so far: we were simply playing with ID 0/1 once again. With the following commit ("selftests: mptcp: add addr argument for del_addr"), it will be different because ID 0 is going to required an address. We don't want errors when trying to delete ID 0 without the address argument.

2021-02-12selftests: mptcp: display warnings on one lineMatthieu Baerts
Before we had this in case of SYN retransmissions: (...) # ns4 MPTCP -> ns2 (10.0.1.2:10034 ) MPTCP (duration 1201ms) [ OK ] # ns4 MPTCP -> ns2 (dead:beef:1::2:10035) MPTCP (duration 1242ms) [ OK ] # ns4 MPTCP -> ns2 (10.0.2.1:10036 ) MPTCP ns2-60143c00-cDZWo4 SYNRX: MPTCP -> MPTCP: expect 11, got # 13 # (duration 6221ms) [ OK ] # ns4 MPTCP -> ns2 (dead:beef:2::1:10037) MPTCP (duration 1427ms) [ OK ] # ns4 MPTCP -> ns3 (10.0.2.2:10038 ) MPTCP (duration 881ms) [ OK ] (...) Now we have: (...) # ns4 MPTCP -> ns2 (10.0.1.2:10034 ) MPTCP (duration 1201ms) [ OK ] # ns4 MPTCP -> ns2 (dead:beef:1::2:10035) MPTCP (duration 1242ms) [ OK ] # ns4 MPTCP -> ns2 (10.0.2.1:10036 ) MPTCP (duration 6221ms) [ OK ] WARN: SYNRX: expect 11, got 13 # ns4 MPTCP -> ns2 (dead:beef:2::1:10037) MPTCP (duration 1427ms) [ OK ] # ns4 MPTCP -> ns3 (10.0.2.2:10038 ) MPTCP (duration 881ms) [ OK ] (...) So we put everything on one line, keep the durations and "OK" aligned and removed duplicated info to short the warning.

2021-02-12selftests: mptcp: dump more info on errorsPaolo Abeni
Even if that may sound completely unlikely, the mptcp implementation is not perfect, yet. When the self-tests report an error we usually need more information of what the scripts currently report. iproute allow provides some additional goodies since a few releases, let's dump them.

2021-02-06selftests: mptcp: add command line arguments for mptcp_join.shGeliang Tang
Since the mptcp_join script is becoming too big, this patch splits it into several smaller chunks, each of them has been defined in a function as a individual test group for several related testcases. Using bash getopts function to parse command line arguments, and invoke each function to do the individual test group. Here are all the arguments: -f subflows_tests -s signal_address_tests -l link_failure_tests -t add_addr_timeout_tests -r remove_tests -a add_tests -6 ipv6_tests -4 v4mapped_tests -b backup_tests -p add_addr_ports_tests -c syncookies_tests -h help Run mptcp_join.sh with no argument will execute all testcases.

2021-02-02selftests: mptcp: add testcases for ADD_ADDR with portGeliang Tang
This patch adds testcases for ADD_ADDR with port and the related MIB counters check in chk_add_nr. The output looks like this: 24 signal address with port syn[ ok ] - synack[ ok ] - ack[ ok ] add[ ok ] - echo [ ok ] - pt [ ok ] syn[ ok ] - synack[ ok ] - ack[ ok ] syn[ ok ] - ack [ ok ] 25 subflow and signal with port syn[ ok ] - synack[ ok ] - ack[ ok ] add[ ok ] - echo [ ok ] - pt [ ok ] syn[ ok ] - synack[ ok ] - ack[ ok ] syn[ ok ] - ack [ ok ] 26 remove single address with port syn[ ok ] - synack[ ok ] - ack[ ok ] add[ ok ] - echo [ ok ] - pt [ ok ] syn[ ok ] - synack[ ok ] - ack[ ok ] syn[ ok ] - ack [ ok ] rm [ ok ] - sf [ ok ] Signed-off-by: Geliang Tang <geliangtang@gmail.com> Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
