* nfsd: use nfs client rpc callback programBenny Halevy2008-09-29
| | | | | | | | | | | | | | | since commit ff7d9756b501744540be65e172d27ee321d86103 "nfsd: use static memory for callback program and stats" do_probe_callback uses a static callback program (NFS4_CALLBACK) rather than the one set in clp->cl_callback.cb_prog as passed in by the client in setclientid (4.0) or create_session (4.1). This patches introduces rpc_create_args.prognumber that allows overriding program->number when creating rpc_clnt. Signed-off-by: Benny Halevy <bhalevy@panasas.com> Signed-off-by: J.

* nfsd: do_probe_callback should not clear rpc statsBenny Halevy2008-09-29
| | | | | | | | | | | | | | | | | | | Now that cb_stats are static (since commit ff7d9756b501744540be65e172d27ee321d86103) there's no need to clear them. Initially I thought it might make sense to do that every callback probing but since the stats are per-program and they are shared between possibly several client callback instances, zeroing them out seems like the wrong thing to do. Note that that commit also introduced a bug since stats.program is also being cleared in the process and it is not restored after the memset as it used to be.

* SUNRPC: Clean up debug messages in rpcb_clnt.cChuck Lever2008-09-29
| | | | | | | | | | | | | | | | The RPCB XDR functions are used for multiple procedures. For instance, rpcb_encode_getaddr() is used for RPCB_GETADDR, RPCB_SET, and RPCB_UNSET. Make the XDR debug messages more generic so they are less confusing. And, unlike in other RPC consumers in the kernel, a single debug flag enables all levels of debug messages in the RPC bind client, including XDR debug messages. Since the XDR decoders already report success or failure in this case, remove redundant debug messages in the mid-level rpcb_register_call() function.

* SUNRPC: Fix up svc_unregister()Chuck Lever2008-09-29
| | | | | | | | | | | | | | | | | With the new rpcbind code, a PMAP_UNSET will not have any effect on services registered via rpcbind v3 or v4. Implement a version of svc_unregister() that uses an RPCB_UNSET with an empty netid string to make sure we have cleared *all* entries for a kernel RPC service when shutting down, or before starting a fresh instance of the service. Use the new version only when CONFIG_SUNRPC_REGISTER_V4 is enabled; otherwise, the legacy PMAP version is used to ensure complete backwards-compatibility with the Linux portmapper daemon.

* SUNRPC: Use short-hand IPv6 ANYADDR for RPCB_SETChuck Lever2008-09-29
| | | | | | | | | | | | | | | Clean up: When doing an RPCB_SET, make the kernel's rpcb client use the shorthand "::" for the universal form of the IPv6 ANY address. Without this patch, rpcbind will advertise: 0000:0000:0000:0000:0000:0000:0000:0000.x.y This is cosmetic only. It cleans up the display of information from /sbin/rpcinfo.

* SUNRPC: Register both netids for AF_INET6 serversChuck Lever2008-09-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TI-RPC is a user-space library of RPC functions that replaces ONC RPC and allows RPC to operate in the new world of IPv6. TI-RPC combines the concept of a transport protocol (UDP and TCP) and a protocol family (PF_INET and PF_INET6) into a single identifier called a "netid." For example, "udp" means UDP over IPv4, and "udp6" means UDP over IPv6. For rpcbind, then, the RPC service tuple that is registered and advertised is: [RPC program, RPC version, service address and port, netid] instead of [RPC program, RPC version, port, protocol] Service address is typically ANYADDR, but can be a specific address of one of the interfaces on a multi-homed host. The third item in the new tuple is expressed as a universal address. The current Linux rpcbind implementation registers a netid for both protocol families when RPCB_SET is done for just the PF_INET6 version of the netid (ie udp6 or tcp6). So registering "udp6" causes a registration for "udp" to appear automatically as well. We've recently determined that this is incorrect behavior. In the TI-RPC world, "udp6" is not meant to imply that the registered RPC service handles requests from AF_INET as well, even if the listener socket does address mapping. "udp" and "udp6" are entirely separate capabilities, and must be registered separately. The Linux kernel, unlike TI-RPC, leverages address mapping to allow a single listener socket to handle requests for both AF_INET and AF_INET6. This is still OK, but the kernel currently assumes registering "udp6" will cover "udp" as well. It registers only "udp6" for it's AF_INET6 services, even though they handle both AF_INET and AF_INET6 on the same port. So svc_register() actually needs to register both "udp" and "udp6" explicitly (and likewise for TCP). Until rpcbind is fixed, the kernel can ignore the return code for the second RPCB_SET call.

* SUNRPC: Support IPv6 when registering kernel RPC servicesChuck Lever2008-09-29
| | | | | | | | | | | | | | | | | | In order to advertise NFS-related services on IPv6 interfaces via rpcbind, the kernel RPC server implementation must use rpcb_v4_register() instead of rpcb_register(). A new kernel build option allows distributions to use the legacy v2 call until they integrate an appropriate user-space rpcbind daemon that can support IPv6 RPC services. I tried adding some automatic logic to fall back if registering with a v4 protocol request failed, but there are too many corner cases. So I just made it a compile-time switch that distributions can throw when they've replaced portmapper with rpcbind. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J.

* SUNRPC: Simplify rpcb_register() APIChuck Lever2008-09-29
| | | | | | | | | | | | | | | Bruce suggested there's no need to expose the difference between an error sending the PMAP_SET request and an error reply from the portmapper to rpcb_register's callers. The user space equivalent of rpcb_register() is pmap_set(3), which returns a bool_t : either the PMAP set worked, or it didn't. Simple. So let's remove the "*okay" argument from rpcb_register() and rpcb_v4_register(), and simply return an error if any part of the call didn't work.

* SUNRPC: Set V6ONLY socket option for RPC listener socketsChuck Lever2008-09-29
| | | | | | | | | | | | | | | | | | | | My plan is to use an AF_INET listener on systems that support only IPv4, and an AF_INET6 listener on systems that can support IPv6. Incoming IPv4 packets will be posted to an AF_INET6 listener with a mapped IPv4 address. Max Matveev <makc@sgi.com> says: Creating a single listener can be dangerous - if net.ipv6.bindv6only is enabled then it's possible to create another listener in v4 namespace on the same port and steal the traffic from the "unifed" listener. You need to disable V6ONLY explicitly via a sockopt to stop that. Set appropriate socket option on RPC server listener sockets to prevent this.

* lockd: don't depend on lockd main loop to end graceJ. Bruce Fields2008-09-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | End lockd's grace period using schedule_delayed_work() instead of a check on every pass through the main loop. After a later patch, we'll depend on lockd to end its grace period even if it's not currently handling requests; so it shouldn't depend on being woken up from the main loop to do so. Also, Nakano Hiroaki (who independently produced a similar patch) noticed that the current behavior is buggy in the face of jiffies wraparound: "lockd uses time_before() to determine whether the grace period has expired. This would seem to be enough to avoid timer wrap-around issues, but, unfortunately, that is not the case. The time_* family of comparison functions can be safely used to compare jiffies relatively close in time, but they stop working after approximately LONG_MAX/2 ticks. nfsd can suffer this problem because the time_before() comparison in lockd() is not performed until the first request comes in, which means that if there is no lockd traffic for more than LONG_MAX/2 ticks we are screwed. "The implication of this is that once time_before() starts misbehaving any attempt from a NFS client to execute fcntl() will be received with a NLM_LCK_DENIED_GRACE_PERIOD message for 25 days (assuming HZ=1000). In other words, the 50 seconds grace period could turn into a grace period of 50 days or more. "Note: This bug was analyzed independently by Oda-san <oda@valinux.co.jp> and myself." Signed-off-by: J.

* locks: allow lockd to process blocked locks during grace periodJ. Bruce Fields2008-09-29
| | | | | | | | | | | | The check here is currently harmless but unnecessary, since, as the comment notes, there aren't any blocked-lock callbacks to process during the grace period anyway. And eventually we want to allow multiple grace periods that come and go for different filesystems over the course of the lifetime of lockd, at which point this check is just going to get in the way.

* knfsd: allocate readahead cache in individual chunksJeff Layton2008-09-29
| | | | | | | | | | | | | | | | | | | I had a report from someone building a large NFS server that they were unable to start more than 585 nfsd threads. It was reported against an older kernel using the slab allocator, and I tracked it down to the large allocation in nfsd_racache_init failing. It appears that the slub allocator handles large allocations better, but large contiguous allocations can often be problematic. There doesn't seem to be any reason that the racache has to be allocated as a single large chunk. This patch breaks this up so that the racache is built up from separate allocations.

* nfsd: permit unauthenticated stat of export rootJ. Bruce Fields2008-09-29
| | | | | | | | | | | | | | | | | | | | | | | | RFC 2623 section 2.3.2 permits the server to bypass gss authentication checks for certain operations that a client may perform when mounting. In the case of a client that doesn't have some form of credentials available to it on boot, this allows it to perform the mount unattended. (Presumably real file access won't be needed until a user with credentials logs in.) Being slightly more lenient allows lots of old clients to access krb5-only exports, with the only loss being a small amount of information leaked about the root directory of the export. This affects only v2 and v3; v4 still requires authentication for all access.

| * | mmc_test: initialize mmc_test_lock staticallyAkinobu Mita2008-09-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mutex mmc_test_lock is initialized at every time mmc_test device is probed. Probing another mmc_test device may break the mutex, if the probe function is called while the mutex is locked. This patch fixes it by statically initializing mmc_test_lock.
