The branch releng/15.0 has been updated by cperciva: URL: https://cgit.FreeBSD.org/src/commit/?id=9c148488a0f15b440d0992bc3e01430f69c1e44e commit 9c148488a0f15b440d0992bc3e01430f69c1e44e Author: Michael Tuexen <tuexen@FreeBSD.org> AuthorDate: 2025-10-20 21:21:47 +0000 Commit: Colin Percival <cperciva@FreeBSD.org> CommitDate: 2025-10-28 01:58:05 +0000 UDP: let udp_pcblist() support UDP and UDP-Lite Provide the IPPROTO_UDP in the arg2 parameter of udp_pcblist() and use this to determine the inpcbinfo. This allows the same function to be used in an upcoming commit to provide the list of pcbs for UDP-Lite just by providing IPPROTO_UDPLITE in the arg2 parameter.
