NFS/SUNRPC: use transport protocol naming

2007-10-09T21:17:53Z

Instead of an { address family, raw IP protocol number }-tuple, use the newly-defined RPC identifier when creating clients in the upper layers. Signed-off-by: Tom Talpey Signed-off-by: Trond Myklebust

SUNRPC: Kill rpc_clnt->cl_oneshot

2007-07-11T03:40:29Z

Replace it with explicit calls to rpc_shutdown_client() or rpc_destroy_client() (for the case of asynchronous calls). Signed-off-by: Trond Myklebust

SUNRPC: RPC buffer size estimates are too large

2007-05-01T05:17:10Z

The RPC buffer size estimation logic in net/sunrpc/clnt.c always significantly overestimates the requirements for the buffer size. A little instrumentation demonstrated that in fact rpc_malloc was never allocating the buffer from the mempool, but almost always called kmalloc. To compute the size of the RPC buffer more precisely, split p_bufsiz into two fields; one for the argument size, and one for the result size. Then, compute the sum of the exact call and reply header sizes, and split the RPC buffer precisely between the two. That should keep almost all RPC buffers within the 2KiB buffer mempool limit. And, we can finally be rid of RPC_SLACK_SPACE! Signed-off-by: Chuck Lever Signed-off-by: Trond Myklebust

[PATCH] knfsd: export nsm_local_state to user space via sysctl

2006-10-04T14:55:18Z

Every NLM call includes the client's NSM state. Currently, the Linux client always reports 0 - which seems not to cause any problems, but is not what the protocol says. This patch exposes the kernel's internal variable to user space via a sysctl, which can be set at system boot time by statd.

[PATCH] knfsd: lockd: optionally use hostnames for identifying peers

2006-10-04T14:55:17Z

This patch adds the nsm_use_hostnames sysctl and module param. If set, lockd will use the client's name (as given in the NLM arguments) to find the NSM handle. This makes recovery work when the NFS peer is multi-homed, and the reboot notification arrives from a different IP than the original lock calls.

[PATCH] knfsd: lockd: make the nsm upcalls use the nsm_handle

2006-10-04T14:55:17Z

This converts the statd upcalls to use the nsm_handle This means that we only register each host once with statd, rather than registering each host/vers/protocol triple. Signed-off-by: Olaf Kirch Signed-off-by: Neil Brown Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] knfsd: lockd: introduce nsm_handle

2006-10-04T14:55:16Z

This patch introduces the nsm_handle, which is shared by all nlm_host objects referring to the same client. With this patch applied, all nlm_hosts from the same address will share the same nsm_handle. A future patch will add sharing by name. Note: this patch changes h_name so that it is no longer guaranteed to be an IP address of the host. When the host represents an NFS server, h_name will be the name passed in the mount call. When the host represents a client, h_name will be the name presented in the lock request received from the client. A h_name is only used for printing informational messages, this change should not be significant.

[PATCH] knfsd: hide use of lockd's h_monitored flag

2006-10-04T14:55:16Z

This patch moves all checks of the h_monitored flag into the nsm_monitor/unmonitor functions. A subsequent patch will replace the mechanism by which we mark a host as being monitored. There is still one occurence of h_monitored outside of mon.c and that is in clntlock.c where we respond to a reboot. The subsequent patch will modify this too.

[PATCH] namespaces: utsname: switch to using uts namespaces

2006-10-02T14:57:21Z

Replace references to system_utsname to the per-process uts namespace where appropriate. This includes things like uname. Changes: Per Eric Biederman's comments, use the per-process uts namespace for ELF_PLATFORM, sunrpc, and parts of net/ipv4/ipconfig.c [jdike@addtoit.com: UML fix] [clg@fr.ibm.com: cleanup] [akpm@osdl.org: build fix] Signed-off-by: Serge E.
