SUNRPC: cleanup ida information when removing sunrpc module

2017-01-24T20:29:24+00:00

After removing sunrpc module, I get many kmemleak information as, unreferenced object 0xffff88003316b1e0 (size 544): comm "gssproxy", pid 2148, jiffies 4294794465 (age 4200.081s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [] kmemleak_alloc+0x4a/0xa0 [] kmem_cache_alloc+0x15e/0x1f0 [] ida_pre_get+0xaa/0x150 [] ida_simple_get+0xad/0x180 [] nlmsvc_lookup_host+0x4ab/0x7f0 [lockd] [] lockd+0x4d/0x270 [lockd] [] param_set_timeout+0x55/0x100 [lockd] [] svc_defer+0x114/0x3f0 [sunrpc] [] svc_defer+0x2d7/0x3f0 [sunrpc] [] rpc_show_info+0x8a/0x110 [sunrpc] [] proc_reg_write+0x7f/0xc0 [] __vfs_write+0xdf/0x3c0 [] vfs_write+0xef/0x240 [] SyS_write+0xad/0x130 [] entry_SYSCALL_64_fastpath+0x1a/0xa9 [] 0xffffffffffffffff I found, the ida information (dynamic memory) isn't cleanup.

SUNRPC: rpc_clnt_add_xprt setup function for NFS layer

2016-09-19T17:08:36+00:00

Use a setup function to call into the NFS layer to test an rpc_xprt for session trunking so as to not leak the rpc_xprt_switch into the nfs layer. Search for the address in the rpc_xprt_switch first so as not to put an unnecessary EXCHANGE_ID on the wire. Signed-off-by: Andy Adamson Signed-off-by: Anna Schumaker

NFSv4: Cap the transport reconnection timer at 1/2 lease period

2016-08-05T23:22:22+00:00

We don't want to miss a lease period renewal due to the TCP connection failing to reconnect in a timely fashion. To ensure this doesn't happen, cap the reconnection timer so that we retry the connection attempt at least every 1/2 lease period. Signed-off-by: Trond Myklebust

sunrpc: Advertise maximum backchannel payload size

2016-05-17T19:47:57+00:00

RPC-over-RDMA transports have a limit on how large a backward direction (backchannel) RPC message can be. Ensure that the NFSv4.x CREATE_SESSION operation advertises this limit to servers. Signed-off-by: Chuck Lever Tested-by: Steve Wise Signed-off-by: Anna Schumaker
