gre tests: Fix gcc warnings on gre netlink tests

2026-02-20T16:45:13+00:00

Avoid using `snl_add_msg_attr_ip` for now and directly use
`snl_add_msg_attr_ip4` to silence gcc warnings.

tests/netlink: fix flaky netlink_sockets:sizes

2025-09-28T14:49:31+00:00

The problem is that fullsocket() creates a socket that has both send and
receive buffers full and as we process messages from the receive buffer we
allow the kernel to continue processing of the send buffer and a new
message may arrive while the test expects that no new messages arrive.
Fix that by creating a socket that has several messages in the receive
buffer, but don't have any in the send buffer.

netlink: underscore snl_get_genl_family_info() to discourage its use

2025-01-20T20:53:37+00:00

This function uses already supposedly opaque struct _getfamily_attrs as
the argument and it fills it with pointers to volatile memory, which makes
it is unsafe for general use.  While here also underscore structures that
hang off the struct _getfamily_attrs.

Small programs like powerd(8) and RPC daemons are converted to use
snl_get_genl_mcast_group() and/or snl_get_genl_family().  The genl(1)
utility was fixed not to mix its own parsers with parsers declared in
netlink_snl_generic.h.
