2025-11-27selftests: complete kselftest include centralizationBala-Vignesh-Reddy
This follow-up patch completes centralization of kselftest.h and ksefltest_harness.h includes in remaining seltests files, replacing all relative paths with a non-relative paths using shared -I include path in lib.mk Tested with gcc-13.3 and clang-18.1, and cross-compiled successfully on riscv, arm64, x86_64 and powerpc arch.

2025-10-06selftests: net: unify the Makefile formatsJakub Kicinski
We get a significant number of conflicts between net and net-next because of selftests Makefile changes. People tend to append new test cases at the end of the Makefile when there's no clear sort order. Sort all networking selftests Makefiles, use the following format: VAR_NAME := \ entry1 \ entry2 \ entry3 \ # end of VAR_NAME Some Makefiles are already pretty close to this.

2025-06-03selftest/net/ovpn: fix TCP socket creationAntonio Quartulli
TCP sockets cannot be created with AF_UNSPEC, but one among the supported family must be used. Since commit 944f8b6abab6 ("selftest/net/ovpn: extend coverage with more test cases") the default address family for all tests was changed from AF_INET to AF_UNSPEC, thus breaking all TCP cases. Restore AF_INET as default address family for TCP listeners. Fixes: 944f8b6abab6 ("selftest/net/ovpn: extend coverage with more test cases") Signed-off-by: Antonio Quartulli <antonio@openvpn.net>
2025-05-15selftest/net/ovpn: extend coverage with more test casesAntonio Quartulli
To increase code coverage, extend the ovpn selftests with the following cases: * connect UDP peers using a mix of IPv6 and IPv4 at the transport layer * run full test with tunnel MTU equal to transport MTU (exercising IP layer fragmentation) * ping "LAN IP" served by VPN peer ("LAN behind a client" test case) Signed-off-by: Antonio Quartulli <antonio@openvpn.net>
2025-05-15selftest/net/ovpn: fix crash in case of getaddrinfo() failureAntonio Quartulli
getaddrinfo() may fail with error code different from EAI_FAIL or EAI_NONAME, however in this case we still try to free the results object, thus leading to a crash. Fix this by bailing out on any possible error. Fixes: 959bc330a439 ("testing/selftests: add test tool and scripts for ovpn module") Signed-off-by: Antonio Quartulli <antonio@openvpn.net>
2025-04-17testing/selftests: add test tool and scripts for ovpn moduleAntonio Quartulli
The ovpn-cli tool can be compiled and used as selftest for the ovpn kernel module. [NOTE: it depends on libmedtls for decoding base64-encoded keys] ovpn-cli implements the netlink and RTNL APIs and can thus be integrated in any script for more automated testing. Along with the tool, a bunch of scripts are provided that perform basic functionality tests by means of network namespaces. These scripts take part to the kselftest automation. The output of the scripts, which will appear in the kselftest reports, is a list of steps performed by the scripts plus some output coming from the execution of `ping`, `iperf` and `ovpn-cli` itself. In general it is useful only in case of failure, in order to understand which step has failed and why. Please note: since peer sockets are tied to the userspace process that created them (i.e. exiting the process will result in closing the socket), every run of ovpn-cli that created one will go to background and enter pause(), waiting for the signal which will allow it to terminate. Termination is accomplished at the end of each script by issuing a killall command.
