[PATCH net] mptcp: sendmsg: reset iter on error redux

2020-08-16 Thread Florian Westphal
This fix wasn't correct: When this function is invoked from the retransmission worker, the iterator contains garbage and resetting it causes a crash. As the work queue should not be performance critical also zero the msghdr struct. Fixes: 35759383133f64d "(mptcp: sendmsg: reset iter on error)" Si
