由 Ted Kim 提交于
Problem reported by: Ted Kim <ted.h.kim@oracle.com>: We have a case where a Linux system and a non-Linux system are trying to interoperate. The Linux host is the active side and starts the connection establishment, but later decides to not go through with the connection setup and does rdma_destroy_id(). The rdma_destroy_id() eventually works its way down to cm_destroy_id() in core/cm.c, where a REJ is sent. The non-Linux system has some trouble recognizing the REJ because of: A. CM states which can't receive the REJ B. Some issues about REJ formatting (missing comm ID) ISSUE A: That part of the spec says, a Consumer Reject REJ can be sent for a connection abort, but it goes further and says: can send a REJ message with a "Consumer Reject" Reason code if they are in a CM state (i.e. REP Rcvd, MRA(REP) Sent, REQ Rcvd, MRA Sent) that allows a REJ to be sent (lines 35-38). Of the states listed there in that sentence, it would seem to limit the active side to using the Consumer Reject (for the abort case) in just the REP-Rcvd and MRA-REP-Sent states. That is basically only after the active side sees a REP (or alternatively goes down the state transitions to timeout in which case a Timeout REJ is sent). As a fix, in cm-destroy-id() move the IB-CM-MRA-REQ-RCVD case to the same as REQ-SENT. Essentially, make a REJ sent after getting an MRA on active side a timeout rather than Consumer- Reject, which is arguably more correct with the CM state diagrams previous to getting a REP.

Commit d4988623 ("IB/qib: use arch_phys_wc_add()") adjusted mtrr inititialization to use the new interface. Unfortunately, the new interface returns a signed value and the patch tested the unsigned wc_cookie. Fix the issue by changing the type of wc_cookie to int. For the success case the ret left at zero to avoid a warning from the caller. For failure wc_cookie is used as the ret.

For listening endpoints bound to the wildcard address, we need to pass the wildcard address mapping to iwpm_get_remote_info() instead of the mapped address of the new child connection. Without this fix, and with iwarp port mapping enabled, each iw_cxgb4 connection that is spawned from a listening endpoint bound to the wildcard address, will generate an annoying dmesg entry about failing to find the remote address mapping info, and the connection state displayed in debugfs under /sys/kernel/debug/iw_cxgb4/<pci-slot-no>/eps will not have the peer's address/port mapping info. The connection still works though.

This driver already makes use of ioremap_wc() on PIO buffers, so convert it to use arch_phys_wc_add(). The qib driver uses a mmap() special case for when PAT is not used, this behaviour used to be determined with a module parameter but since we have been asked to just remove that module parameter this checks for the WC cookie, if not set we can assume PAT was used. If its set we do what we used to do for the mmap for when MTRR was enabled. The removal of the module parameter is OK given that Andy notes that even if users of module parameter are still around it will not prevent loading of the module on recent kernels.

While unmapping an ODP writable page, the dirty bit of the page is set. In order to do so, the head of the compound page is found.

Currently the iw_cxgb4 implementation requires the qp and cq qid densities to match as well as the qp and cq id ranges. So fail a device open if the device configuration doesn't meet the requirements. The reason for these restictions has to do with the fact that IQ qid X has a UGTS register in the same bar2 page as EQ qid X. Thus both qids need to be allocated to the same user process for security reasons. The logic that does this (the qpid allocator in iw_cxgb4/resource.c) handles this but requires the above restrictions.
