[PATCH net v3 0/2] mptcp: Prevent tcp_push() crash and selftest temp file buildup

From: Mat Martineau <hidden>
Date: 2021-09-01 17:15:48
Also in: mptcp

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
