These are two fixes for the net tree, addressing separate issues. Patch 1 addresses a divide-by-zero crash seen in syzkaller and also reported by a user on the netdev list. This changes MPTCP code so tcp_push() cannot be called with an invalid (0) mss_now value. Patch 2 fixes a selftest temp file cleanup issue that consumes excessive disk space when running repeated tests. v3: Respin after net-next merge v2: Make suggested changes to lockdep check and indentation in patch 1 Matthieu Baerts (1): selftests: mptcp: clean tmp files in simult_flows Paolo Abeni (1): mptcp: fix possible divide by zero net/mptcp/protocol.c | 76 +++++++++---------- .../selftests/net/mptcp/simult_flows.sh | 4 +- 2 files changed, 37 insertions(+), 43 deletions(-) base-commit: 780aa1209f88fd96d40572b62df922662f2b896d -- 2.33.0
