2012-03-21SUNRPC: Kill compiler warning when RPC_DEBUG is unsetChuck Lever1-2/+2
Loads of these: linux/net/sunrpc/rpcb_clnt.c:942:2: warning: suggest braces around empty body in ‘do’ statement [-Wempty-body] show up when I unset CONFIG_PROC_SYSCTL.

2012-03-20SUNRPC/NFS: Add Kbuild dependencies for NFS_DEBUG/RPC_DEBUGTrond Myklebust1-1/+1
This allows us to turn on/off the dprintk() debugging interfaces for those distributions that don't ship the 'rpcdebug' utility. It also allows us to add Kbuild dependencies. Specifically, we already know that dprintk() in general relies on CONFIG_SYSCTL. Now it turns out that the NFS dprintks depend on CONFIG_CRC32 after we added support for the filehandle hash.

2012-03-03SUNRPC: Use RCU to dereference the rpc_clnt.cl_xprt fieldTrond Myklebust1-0/+13
A migration event will replace the rpc_xprt used by an rpc_clnt. To ensure this can be done safely, all references to cl_xprt must now use a form of rcu_dereference(). Special care is taken with rpc_peeraddr2str(), which returns a pointer to memory whose lifetime is the same as the rpc_xprt.

2012-02-16SUNRPC: Use KERN_DEFAULT for debugging printk'sChuck Lever1-1/+5
Our dprintk() debugging facility doesn't specify any verbosity level for it's printk() calls, but it should. The default verbosity for printk's is KERN_DEFAULT. You might argue that these are debugging printk's and thus the verbosity should be KERN_DEBUG. That would mean that to see NFS and SUNRPC debugging output an admin would also have to boost the syslog verbosity, which would be insufferably noisy.

2012-02-15SUNRPC: Ensure that we can trace waitqueues when !defined(CONFIG_SYSCTL)Trond Myklebust1-0/+3
The tracepoint code relies on the queue->name being defined in order to be able to display the name of the waitqueue on which an RPC task is sleeping.

2009-12-15sunrpc: Clean never used include filesBoaz Harrosh1-3/+0
Remove include of two headers never used by this file. Doing so exposed a missing #include <linux/types.h> in include/linux/sunrpc/rpc_rdma.h. I did not see any other users dependency but if exist they should be fixed since these headers are totally irrelevant to here. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> Signed-off-by: J.

2008-02-02svc: Make svc_sock the tcp/udp transportTom Tucker1-1/+0
Make TCP and UDP svc_sock transports, and register them with the svc transport core. A transport type (svc_sock) has an svc_xprt as its first member, and calls svc_xprt_init to initialize this field.

2008-02-02svc: Add an svc transport classTom Tucker1-0/+1
The transport class (svc_xprt_class) represents a type of transport, e.g. udp, tcp, rdma. A transport class has a unique name and a set of transport operations kept in the svc_xprt_ops structure. A transport class can be dynamically registered and unregisterd. The svc_xprt_class represents the module that implements the transport type and keeps reference counts on the module to avoid unloading while there are active users. The endpoint (svc_xprt) is a generic, transport independent endpoint that can be used to send and receive data for an RPC service. It inherits it's operations from the transport class. A transport driver module registers and unregisters itself with svc sunrpc by calling svc_reg_xprt_class, and svc_unreg_xprt_class respectively.

2007-11-27SUNRPC: remove NFS/RDMA client's binary sysctlsJames Lentini1-5/+0
Support for binary sysctls is being deprecated in 2.6.24. Since there are no applications using the NFS/RDMA client's binary sysctls, it makes sense to remove them. The patch below does this while leaving the /proc/sys interface unchanged. Please consider this for 2.6.24.

This implements the configuration and building of the core transport switch implementation of the rpcrdma transport. Stubs are provided for the rpcrdma protocol handling, and the infiniband/iwarp verbs interface. These are provided in following patches.

2007-05-01SUNRPC: introduce rpcbind: replacement for in-kernel portmapperChuck Lever1-0/+1
Introduce a replacement for the in-kernel portmapper client that supports all 3 versions of the rpcbind protocol. This code is not used yet. Original code by Groupe Bull updated for the latest kernel, with multiple bug fixes. Note that rpcb_clnt.c does not yet support registering via versions 3 and 4 of the rpcbind protocol. That is planned for a later patch. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2005-09-23[PATCH] RPC: allow RPC client's port range to be adjustableChuck Lever1-0/+2
Select an RPC client source port between 650 and 1023 instead of between 1 and 800. The old range conflicts with a number of network services. Provide sysctls to allow admins to select a different port range. Note that this doesn't affect user-level RPC library behavior, which still uses 1 to 800. Based on a suggestion by Olaf Kirch <okir@suse.de>. Test-plan: Repeated mount and unmount. Destructive testing. Idle timeouts.

2005-09-23[PATCH] RPC: transport switch function namingChuck Lever1-0/+1
Introduce block header comments and a function naming convention to the socket transport implementation. Provide a debug setting for transports that is separate from RPCDBG_XPRT. Eliminate xprt_default_timeout(). Provide block comments for exposed interfaces in xprt.c, and eliminate the useless obvious comments. Convert printk's to dprintk's.

2005-04-17Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+99
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
