truss: add support for decoding Netlink messages

2026-04-03T06:52:29Z

Netlink usage is growing in FreeBSD. This patch adds support to `truss(1)` to decode Netlink headers in sendmsg/recvmsg calls, making debugging network configuration tools significantly easier. Changes: libsysdecode: Add `sysdecode_netlink()` to parse struct `nlmsghdr`. truss: Detect `AF_NETLINK` sockets and decode the message payload.

truss: Properly display first argument to nmount

2025-10-31T16:15:06Z

The first argument to nmount(2) is an nvlist in the form of an iovec, which truss already knows how to decode. Set the correct flag so this happens automatically. MFC after: 1 week PR: 290667
