Detail

In the Linux kernel, the following vulnerability has been resolved:

RDMA/siw: Fix duplicated reported IW_CM_EVENT_CONNECT_REPLY event

If siw_recv_mpa_rr returns -EAGAIN, it means that the MPA reply hasn't been received completely, and should not report IW_CM_EVENT_CONNECT_REPLY in this case. This may trigger a call trace in iw_cm. A simple way to trigger this:
server: ib_send_lat
client: ib_send_lat -R

The call trace looks like this:

kernel BUG at drivers/infiniband/core/iwcm.c:894!
invalid opcode: 0000 [#1] PREEMPT SMP NOPTI
