Patch 2 sets the expected poll() events on SEND_SHUTDOWN. Patch 3 fixes a retranmit crash and unneeded retransmissions. Patch 4 fixes possible uninitialized data on the error path during socket creation. Patch 5 addresses a problem with MPTCP window updates. Patch 6 fixes a case where MPTCP retransmission can get stuck. Paolo Abeni (6): mptcp: deliver ssk errors to msk mptcp: fix poll after shutdown mptcp: fix spurious retransmissions mptcp: init mptcp request socket earlier mptcp: better msk receive window updates mptcp: add a missing retransmission timer scheduling net/mptcp/options.c | 10 +++--- net/mptcp/protocol.c | 55 +++++++++++++++++++---------- net/mptcp/protocol.h | 18 ++++------ net/mptcp/subflow.c | 83 +++++++++++++++++++++++++++++++------------- 4 files changed, 107 insertions(+), 59 deletions(-) base-commit: 8a28af7a3e85ddf358f8c41e401a33002f7a9587
