netlink: specs: rt_addr: pull the ifa- prefix out of the names 2025-04-04T14:36:06+00:00 Jakub Kicinski kuba@kernel.org 2025-04-03T01:37:05+00:00 0c8e30252d9fe8127f90b7a0a293872b368ebf3c YAML specs don't normally include the C prefix name in the name of the YAML attr. Remove the ifa- prefix from all attributes in addr-attrs and specify name-prefix instead. This is a bit risky, hopefully there aren't many users out there.

selftests/net: Add selftest for IPv4 RTM_GETMULTICAST support 2025-02-11T10:26:53+00:00 Yuyang Huang yuyanghuang@google.com 2025-02-07T11:08:36+00:00 4f280376e5318f17f7388999f9a0098ccaae931d This change introduces a new selftest case to verify the functionality of dumping IPv4 multicast addresses using the RTM_GETMULTICAST netlink message. The test utilizes the ynl library to interact with the netlink interface and validate that the kernel correctly reports the joined IPv4 multicast addresses. To run the test, execute the following command: $ vng -v --user root --cpus 16 -- \ make -C tools/testing/selftests TARGETS=net \ TEST_PROGS=rtnetlink.py TEST_GEN_PROGS="" run_tests Cc: Maciej Żenczykowski <maze@google.com> Cc: Lorenzo Colitti <lorenzo@google.com> Signed-off-by: Yuyang Huang <yuyanghuang@google.com> Link: https://patch.msgid.link/20250207110836.2407224-2-yuyanghuang@google.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>
