Further it adds flexibility in establishing paths and from both ends of MPTCP connections. v6: -Dropped framework and functionality around the use of kernel listening sockets for receiving MPJs. v7: -Fixed bug caught by the CI build. v8: -Fixed logic to achieve the desired outcome of not responding to address advertisements when a userspace PM is offline. -Factored out minor changes to mptcp_pm_is_userspace() to be squashed into an earlier commit. Kishen Maloor (6): Squash-to: mptcp: Bypass kernel PM when userspace PM is enabled mptcp: bypass in-kernel PM restrictions for non-kernel PMs mptcp: store remote id from MP_JOIN SYN/ACK in local ctx mptcp: reflect remote port (not 0) in ANNOUNCED events mptcp: establish subflows from either end of connection mptcp: expose server_side attribute in MPTCP netlink events include/uapi/linux/mptcp.h | 1 + net/mptcp/options.c | 4 ++-- net/mptcp/pm.c | 21 +++++++++++++++++---- net/mptcp/pm_netlink.c | 24 +++++++++++++++++++++--- net/mptcp/protocol.c | 5 +---- net/mptcp/protocol.h | 22 ++++++++++++++++------ net/mptcp/subflow.c | 5 ++++- 7 files changed, 62 insertions(+), 20 deletions(-) base-commit: 2a9f09777d24fc18cc62762b398054d3961ad8bf --- 2.31.1
