  • b26f9b994   RDMA/cma: Pass QP type into rdma_create_id() ... Browse Code »

    The RDMA CM currently infers the QP type from the port space selected
    by the user. In the future (eg with RDMA_PS_IB or XRC), there may not
    be a 1-1 correspondence between port space and QP type. For netlink
    export of RDMA CM state, we want to export the QP type to userspace,
    so it is cleaner to explicitly associate a QP type to an ID.

    Modify rdma_create_id() to allow the user to specify the QP type, and
    use it to make our selections of datagram versus connected mode.

  • 5c635e09c   RPCRDMA: Fix FRMR registration/invalidate handling. ... Browse Code »

    When the rpc_memreg_strategy is 5, FRMR are used to map RPC data.
    This mode uses an FRMR to map the RPC data, then invalidates
    (i.e. unregisers) the data in xprt_rdma_free. These FRMR are used
    across connections on the same mount, i.e. if the connection goes
    away on an idle timeout and reconnects later, the FRMR are not
    destroyed and recreated.

    This creates a problem for transport errors because the WR that
    invalidate an FRMR may be flushed (i.e. fail) leaving the
    FRMR valid. When the FRMR is later used to map an RPC it will fail,
    tearing down the transport and starting over. Over time, more and
    more of the FRMR pool end up in the wrong state resulting in
    seemingly random disconnects.

    This fix keeps track of the FRMR state explicitly by setting it's
    state based on the successful completion of a reg/inv WR. If the FRMR
    is ever used and found to be in the wrong state, an invalidate WR
    is prepended, re-syncing the FRMR state and avoiding the connection loss.

  • bd7ea31b9   RPCRDMA: Fix to XDR page base interpretation in marshalling logic. ... Browse Code »

    The RPCRDMA marshalling logic assumed that xdr->page_base was an
    offset into the first page of xdr->page_list. It is in fact an
    offset into the xdr->page_list itself, that is, it selects the
    first page in the page_list and the offset into that page.

    The symptom depended in part on the rpc_memreg_strategy, if it was
    FRMR, or some other one-shot mapping mode, the connection would get
    torn down on a base and bounds error. When the badly marshalled RPC
    was retransmitted it would reconnect, get the error, and tear down the
    connection again in a loop forever. This resulted in a hung-mount. For
    the other modes, it would result in silent data corruption. This bug is
    most easily reproduced by writing more data than the filesystem
    has space for.

    This fix corrects the page_base assumption and otherwise simplifies
    the iov mapping logic.

    * Create and use svc_rdma_wq instead of using the system workqueue and
    flush_scheduled_work(). This workqueue is necessary to serve as
    flushing domain for rdma->sc_work which is used to destroy itself
    and thus can't be flushed explicitly.

    * Replace cancel_delayed_work() + flush_scheduled_work() with
    cancel_delayed_work_sync().

    * Implement synchronous connect in xprt_rdma_connect() using
    flush_delayed_work() on the rdma_connect work instead of using
    flush_scheduled_work().

    This is to prepare for the deprecation and removal of
    flush_scheduled_work().

  • b432e6b3d   svcrdma: Change DMA mapping logic to avoid the page_address kernel API ... Browse Code »

    There was logic in the send path that assumed that a page containing data
    to send to the client has a KVA. This is not always the case and can result
    in data corruption when page_address returns zero and we end up DMA mapping
    zero.

    This patch changes the bus mapping logic to avoid page_address() where
    necessary and converts all calls from ib_dma_map_single to ib_dma_map_page
    in order to keep the map/unmap calls symmetric.

  • b48fa6b99   sunrpc: centralise most calls to svc_xprt_received ... Browse Code »

    svc_xprt_received must be called when ->xpo_recvfrom has finished
    receiving a message, so that the XPT_BUSY flag will be cleared and
    if necessary, requeued for further work.

    This call is currently made in each ->xpo_recvfrom function, often
    from multiple different points. In each case it is the earliest point
    on a particular path where it is known that the protection provided by
    XPT_BUSY is no longer needed.

    However there are (still) some error paths which do not call
    svc_xprt_received, and requiring each ->xpo_recvfrom to make the call
    does not encourage robustness.

    So: move the svc_xprt_received call to be made just after the
    call to ->xpo_recvfrom(), and move it of the various ->xpo_recvfrom
    methods.

    This means that it may not be called at the earliest possible instant,
    but this is unlikely to be a measurable performance issue.

    Note that there are still other calls to svc_xprt_received as it is
    also needed when an xprt is newly created.

  • 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

    …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.
