Subject: mptcp: pm: kernel: flush: do not reset ADD_ADDR limit
|
|
|
|
A flush of the MPTCP endpoints should not affect the MPTCP limits. In
|
|
other words, 'ip mptcp endpoint flush' should not change 'ip mptcp
|
|
limits'.
|
|
|
|
But it was the case: the MPTCP_PM_ATTR_RCV_ADD_ADDRS (add_addr_accepted)
|
|
limit was reset by accident. Removing the reset of this counter during a
|
|
flush fixes this issue.
