__ib_umem_release calls dma_unmap_sg with a different number of sg_entries than ib_umem_get uses for dma_map_sg. This might cause trouble for implementations that merge sglist entries and results in the following dma debug complaint: DMA-API: device driver frees DMA sg list with different entry count [map count=2] [unmap count=1] Fix it by using the correct value.

The array ib_mad_mgmt_class_table.method_table has MAX_MGMT_CLASS (80) elements. Hence compare the array index with that value instead of with IB_MGMT_MAX_METHODS (128). This patch avoids that Coverity reports the following: Overrunning array class->method_table of 80 8-byte elements at element index 127 (byte offset 1016) using index convert_mgmt_class(mad_hdr->mgmt_class) (which evaluates to 127).

The function usnic_ib_qp_grp_get_chunk only returns an ERR_PTR value or a valid pointer, never NULL. The same is true of get_qp_res_chunk, which just returns the result of calling usnic_ib_qp_grp_get_chunk. Simplify IS_ERR_OR_NULL to IS_ERR in both cases. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression t,e; @@ t = \(usnic_ib_qp_grp_get_chunk(...)\|get_qp_res_chunk(...)\) ... when != t=e - IS_ERR_OR_NULL(t) + IS_ERR(t) @@ expression t,e,e1; @@ t = \(usnic_ib_qp_grp_get_chunk(...)\|get_qp_res_chunk(...)\) ... when != t=e ?- t ?

Hans Westgaard Ry authored
from "InfiBand Architecture Specifications Volume 1": A QP is said to have a stale connection when only one side has connection information. A stale connection may result if the remote CM had dropped the connection and sent a DREQ but the DREQ was never received by the local CM. Alternatively the remote CM may have lost all record of past connections because its node crashed and rebooted, while the local CM did not become aware of the remote node's reboot and therefore did not clean up stale connections. and: A local CM may receive a REQ/REP for a stale connection. It shall abort the connection issuing REJ to the REQ/REP. It shall then issue DREQ with "DREQ:remote QPN” set to the remote QPN from the REQ/REP. This patch solves a problem with reuse of QPN. Current codebase, that is IPoIB, relies on a REAP-mechanism to do cleanup of the structures in CM. A problem with this is the timeconstants governing this mechanism; they are up to 768 seconds and the interface may look inresponsive in that period. Issuing a DREQ (and receiving a DREP) does the necessary cleanup and the interface comes up.

Currently when calling mlx5_add_flow_rule we accept only one flow destination, this commit allows to pass multiple destinations. This change forces us to change the return structure to a more flexible one. We introduce a flow handle (struct mlx5_flow_handle), it holds internally the number for rules created and holds an array where each cell points the to a flow rule. From the consumers (of mlx5_add_flow_rule) point of view this change is only cosmetic and requires only to change the type of the returned value they store. From the core point of view, we now need to use a loop when allocating and deleting rules (e.g given to us a flow handler).

When adding a new rule, if we can match it with compare_match_value and flow tag we might be able to insert the rule to the same fte. In order to do that, there must be an overlap between the actions of the fte and the new rule. When updating the action of an existing fte, we must tell the firmware we are doing so.

An fte status becomes FS_FTE_STATUS_EXISTING only after it was created in HW. We can use this in order to simplify the logic on what firmware command to use.

TSAR (stands for Transmit Scheduling ARbiter) is a hardware component that is responsible for selecting the next entity to serve on the transmit path. The arbitration defines the QoS policy between the agents connected to the TSAR. The TSAR is a consist two main features: 1) BW Allocation between agents: The TSAR implements a defecit weighted round robin between the agents. Each agent attached to the TSAR is assigned with a weight and it is awarded transmission tokens according to this weight. 2) Rate limer per agent: Each agent attached to the TSAR is (optionally) assigned with a rate limit. TSAR will not allow scheduling for an agent exceeding its defined rate limit. In this patch we implement the API of manipulating the TSAR.

Pull x86 bugfix from Thomas Gleixner: "A single bugfix for the recent changes related to registering the boot cpu when this has not happened before prefill_possible_map(). The main problem with this change got fixed already, but we missed the case where the local APIC is not yet mapped, when prefill_possible_map() is invoked, so the registration of the boot cpu which has the APIC bit set in CPUID will explode. I should have seen that issue earlier, but all I can do now is feeling embarassed" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/smpboot: Init apic mapping before usage
