This adds a ynl spec for the gtp genetlink family, a small driver fix it needed, and a selftest.
Patch 1: the GET and dump replies carried the family id in the command field, so ynl dropped them. Use GTP_CMD_GETPDP instead. Patch 2: the spec (NEWPDP/DELPDP/GETPDP/ECHOREQ), no uapi change. Patch 3: a selftest that adds, dumps and deletes PDP contexts. The multicast notifications are not in the spec: they reuse the request command values, which the ynl C generator can't express with the current uapi header. I can look at generator support as a follow-up. v5: - ynl: add CFLAGS_gtp so the generated code builds with older headers - spec: doc fixes (notifications, version 0, echoreq ms-address, ms-addr6 /64), min-len for the IPv6 attributes - selftest: only skip when GTP is unavailable, close the ynl handle v4: - spec: request/reply attributes now match the handlers - selftest: fix the gtp.ko autoload crash, check ENOENT, delete by TEI and by MS address v4: https://lore.kernel.org/netdev/[email protected]/ v3: https://lore.kernel.org/netdev/[email protected]/ v2: https://lore.kernel.org/netdev/[email protected]/ Anil Kaushik (3): gtp: set a valid genl command in PDP context get and dump replies netlink: specs: add genetlink-legacy spec for GTP selftests: net: add a test for the gtp netlink family Documentation/netlink/specs/gtp.yaml | 183 ++++++++++++++++++ MAINTAINERS | 2 + drivers/net/gtp.c | 4 +- tools/net/ynl/Makefile.deps | 1 + tools/testing/selftests/net/Makefile | 1 + tools/testing/selftests/net/config | 1 + tools/testing/selftests/net/gtp.py | 122 ++++++++++++ .../testing/selftests/net/lib/py/__init__.py | 5 +- tools/testing/selftests/net/lib/py/ynl.py | 8 +- 9 files changed, 322 insertions(+), 5 deletions(-) create mode 100644 Documentation/netlink/specs/gtp.yaml create mode 100755 tools/testing/selftests/net/gtp.py -- 2.25.1
