ib_uverbs_ex_create_qp follows the extension verbs mechanism. New features (for example, QP creation flags field which is added in a downstream patch) could used via user-space libraries without breaking the ABI. Signed-off-by:

When calculating the minimum ird in c4iw_accept_cr(), we need to always have a value of at least 1 if the RTR message is a 0B read. The code was incorrectly using ep->ord for this logic which was incorrectly adjusting the ird and causing incorrect ord/ird negotiation when using MPAv2 to negotiate these values. Signed-off-by:

The INIT_UDATA() macro requires a pointer or unsigned long argument for both input and output buffer, and all callers had a cast from when the code was merged until a recent restructuring, so now we get core/uverbs_cmd.c: In function 'ib_uverbs_create_cq': core/uverbs_cmd.c:1481:66: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] This makes the code behave as before by adding back the cast to unsigned long.

ib_send_cm_sidr_rep could sometimes erase the node from the sidr (depending on errors in the process). Since ib_send_cm_sidr_rep is called both from cm_sidr_req_handler and cm_destroy_id, cm_id_priv could be either erased from the rb_tree twice or not erased at all. Fixing that by making sure it's erased only once before freeing cm_id_priv. Fixes: a977049d ('[PATCH] IB: Add the kernel CM implementation') Signed-off-by:

Haggai Eran authored
When discussing the patches to demux ids in rdma_cm instead of ib_cm, it was decided that it is best to use the P_Key value in the packet headers. However, the mlx5 and ipath drivers are currently unable to send correct P_Key values in GMP headers. They always send using a single P_Key that is set during the GSI QP initialization. Change the rdma_cm code to look at the P_Key value that is part of the packet payload as a workaround. Once the drivers are fixed this patch can be reverted.

The netdev checks recently added to RDMA CM expect a valid netdev to be found for both InfiniBand and RoCE, but the code that find a netdev is only implemented for InfiniBand. Currently RoCE doesn't provide an API to find the netdev matching a given set of parameters, so this patch just disables the netdev enforcement for each incoming connections when the link layer is RoCE.

Two enum members IB_DEVICE_RC_IP_CSUM and IB_DEVICE_RAW_IP_CSUM are added to ib_device_cap_flags. Device should set these two flags if they support insertion of UDP and TCP checksum on outgoing IPv4 messages and can verify the validity of checksum for incoming IPv4 messages, for RC IPoIB and RAW over Ethernet respectively. They are similar to IB_DEVICE_UD_IP_CSUM. Signed-off-by:
