| | | | | | | * RDMA/nes: Fix crash in nes_accept()Faisal Latif2009-12-092-28/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While running IMP_EXT's window test, we saw a crash in nes_accept(). Here is the sequence of what happened: (1) In MVAPICH2, connect request is received for port #0. FIX: Add a nes_connect() check to make sure local or remote tcp port is not 0. (2) Remote node's (passive) TCP stack sends a reset when it gets a connect request because of port = 0. Active side set the connect error to IW_CM_EVENT_STATUS_REJECTED when it received the RST from remote node. FIX: The corect error code is -ECONNRESET. (3) Wrong error code of IW_CM_EVENT_STATUS_REJECTED causes the core to destroy its listener ports. Here there are connections that may have sent an MPA request up and waiting for accept or reject. But the listener and its cm_nodes have been freed already causing the crash noticed. FIX: The cm_node is freed only if its state is not NES_CM_STATE_MPAREQ_RCVD. If cm_node's state is NES_CM_STATE_MPAREQ_RCVD then its new state is set to NES_CM_STATE_LISTENER_DESTROYED and it is not freed. When nes_accept() or nes_reject() is received, its state is checked for NES_CM_STATE_LISTENER_DESTROYED and in this case the cm_node is freed and error is returned.

| | | | | | * | IB/mlx4: Remove limitation on LSO header sizeEli Cohen2009-11-122-13/+13

This patch removes this limitation by setting the WQE RR for large headers thus allowing LSO headers of any size. The extra buffer reserved for MLX4_IB_QP_LSO QPs has been doubled, from 64 to 128 bytes, assuming this is reasonable upper limit for header length. Also, this patch will cause IB_DEVICE_UD_TSO to be set only for HCA FW versions that set MLX4_DEV_CAP_FLAG_BLH; e.g. FW version 2.6.000 and higher.

* | walk system ram rangeKAMEZAWA Hiroyuki2009-09-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally, walk_memory_resource() was introduced to traverse all memory of "System RAM" for detecting memory hotplug/unplug range. For doing so, flags of IORESOUCE_MEM|IORESOURCE_BUSY was used and this was enough for memory hotplug. But for using other purpose, /proc/kcore, this may includes some firmware area marked as IORESOURCE_BUSY | IORESOUCE_MEM. This patch makes the check strict to find out busy "System RAM". Note: PPC64 keeps their own walk_memory_resouce(), which walk through ppc64's lmb informaton. Because old kclist_add() is called per lmb, this patch makes no difference in behavior, finally. And this patch removes CONFIG_MEMORY_HOTPLUG check from this function. Because pfn_valid() just show "there is memmap or not* and cannot be used for "there is physical memory or not", this function is useful in generic to scan physical memory range.

Fixed up trivial conflicts: - arch/x86/include/asm/socket.h converted to <asm-generic/socket.h> in the x86 tree. The generic header has the same new #define's, so that works out fine. - drivers/net/tun.c fix conflict between 89f56d1e9 ("tun: reuse struct sock fields") that switched over to using 'tun->socket.sk' instead of the redundantly available (and thus removed) 'tun->sk', and 2b980dbd ("lsm: Add hooks to the TUN driver") which added a new 'tun->sk' use.
