2009-11-19RDMA/cm: fix loopback address supportSean Hefty2-4/+4
The RDMA CM is intended to support the use of a loopback address when establishing a connection; however, the behavior of the CM when loopback addresses are used is confusing and does not always work, depending on whether loopback was specified by the server, the client, or both. The defined behavior of rdma_bind_addr is to associate an RDMA device with an rdma_cm_id, as long as the user specified a non- zero address. (ie they weren't just trying to reserve a port) Currently, if the loopback address is passed to rdam_bind_addr, no device is associated with the rdma_cm_id. Fix this. If a loopback address is specified by the client as the destination address for a connection, it will fail to establish a connection. This is true even if the server is listing across all addresses or on the loopback address itself. The issue is that the server tries to translate the IP address carried in the REQ message to a local net_device address, which fails. The translation is not needed in this case, since the REQ carries the actual HW address that should be used. Finally, cleanup loopback support to be more transport neutral. Replace separate calls to get/set the sgid and dgid from the device address to a single call that behaves correctly depending on the format of the device address. And support both IPv4 and IPv6 address formats.

2009-10-30RDS: Fix potential race around rds_i[bw]_allocationAndy Grover2-6/+8
"At rds_ib_recv_refill_one(), it first executes atomic_read(&rds_ib_allocation) for if-condition checking, and then executes atomic_inc(&rds_ib_allocation) if the condition was not satisfied. However, if any other code which updates rds_ib_allocation executes between these two atomic operation executions, it seems that it may result race condition. (especially when rds_ib_allocation + 1 == rds_ib_sysctl_max_recv_allocation)" This patch fixes this by using atomic_inc_unless to eliminate the possibility of allocating more than rds_ib_sysctl_max_recv_allocation and then decrementing the count if the allocation fails. It also makes an identical change to the iwarp transport. Reported-by: Shin Hong <hongshin@gmail.com> Signed-off-by: Andy Grover <andy.grover@oracle.com> Signed-off-by: David S.

2009-10-30RDS: Add GET_MR_FOR_DEST sockoptAndy Grover3-0/+28
RDS currently supports a GET_MR sockopt to establish a memory region (MR) for a chunk of memory. However, the fastreg method ties a MR to a particular destination. The GET_MR_FOR_DEST sockopt allows the remote machine to be specified, and thus support for fastreg (aka FRWRs). Note that this patch does *not* do all of this - it simply implements the new sockopt in terms of the old one, so applications can begin to use the new sockopt in preparation for cutover to FRWRs.

2009-10-18inet: rename some inet_sock fieldsEric Dumazet1-4/+4
In order to have better cache layouts of struct sock (separate zones for rx/tx paths), we need this preliminary patch. Goal is to transfert fields used at lookup time in the first read-mostly cache line (inside struct sock_common) and move sk_refcnt to a separate cache line (only written by rx path) This patch adds inet_ prefix to daddr, rcv_saddr, dport, num, saddr, sport and id fields. This allows a future patch to define these fields as macros, like sk_refcnt, without name clashes. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

The big differences between RDS 3.0 and 3.1 are protocol-level flow control, and with 3.1 the header is in front of the data. The header always ends up in the header buffer, and the data goes in the data page. In 3.0 our "header" is a trailer, and will end up either in the data page, the header buffer, or split across the two. Since 3.1 is backwards- compatible with 3.0, we need to continue to support these cases. This patch does that -- if using RDS 3.0 wire protocol, it will copy the header from wherever it ended up into the header buffer.

2009-04-21FRV: Fix the section attribute on UP DECLARE_PER_CPU()David Howells1-1/+1
In non-SMP mode, the variable section attribute specified by DECLARE_PER_CPU() does not agree with that specified by DEFINE_PER_CPU(). This means that architectures that have a small data section references relative to a base register may throw up linkage errors due to too great a displacement between where the base register points and the per-CPU variable. On FRV, the .h declaration says that the variable is in the .sdata section, but the .c definition says it's actually in the .data section. The linker throws up the following errors: kernel/built-in.o: In function `release_task': kernel/exit.c:78: relocation truncated to fit: R_FRV_GPREL12 against symbol `per_cpu__process_counts' defined in .data section in kernel/built-in.o kernel/exit.c:78: relocation truncated to fit: R_FRV_GPREL12 against symbol `per_cpu__process_counts' defined in .data section in kernel/built-in.o To fix this, DECLARE_PER_CPU() should simply apply the same section attribute as does DEFINE_PER_CPU(). However, this is made slightly more complex by virtue of the fact that there are several variants on DEFINE, so these need to be matched by variants on DECLARE.
