From: Asbjørn Sloth Tønnesen Date: Wed, 11 Sep 2024 09:10:02 +0000 (+0000) Subject: netlink: specs: mptcp: fix port endianness X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=09a45a5553792bbf20beba0a1ac90b4692324d06;p=users%2Fjedix%2Flinux-maple.git netlink: specs: mptcp: fix port endianness The MPTCP port attribute is in host endianness, but was documented as big-endian in the ynl specification. Below are two examples from net/mptcp/pm_netlink.c showing that the attribute is converted to/from host endianness for use with netlink. Import from netlink: addr->port = htons(nla_get_u16(tb[MPTCP_PM_ADDR_ATTR_PORT])) Export to netlink: nla_put_u16(skb, MPTCP_PM_ADDR_ATTR_PORT, ntohs(addr->port)) Where addr->port is defined as __be16. No functional change intended.
