* svc: Clean up deferred requests on transport destructionTom Tucker2009-01-07
| | | | | | | | | | | | | | A race between svc_revisit and svc_delete_xprt can result in deferred requests holding references on a transport that can never be recovered because dead transports are not enqueued for subsequent processing. Check for XPT_DEAD in revisit to clean up completing deferrals on a dead transport and sweep a transport's deferred queue to do the same for queued but unprocessed deferrals.

* svc: Move kfree of deferral record to common codeTom Tucker2009-01-07
| | | | | | | | | | | | | | | The rqstp structure has a pointer to a svc_deferred_req record that is allocated when requests are deferred. This record is common to all transports and can be freed in common code. Move the kfree of the rq_deferred to the common svc_xprt_release function. This also fixes a memory leak in the RDMA transport which does not kfree the dr structure in it's version of the xpo_release_rqst callback.

* sunrpc: add sv_maxconn field to svc_serv (try #3)Jeff Layton2009-01-06
| | | | | | | | | | | | | | | | | | | | | | | | svc_check_conn_limits() attempts to prevent denial of service attacks by having the service close old connections once it reaches a threshold. This threshold is based on the number of threads in the service: (serv->sv_nrthreads + 3) * 20 Once we reach this, we drop the oldest connections and a printk pops to warn the admin that they should increase the number of threads. Increasing the number of threads isn't an option however for services like lockd. We don't want to eliminate this check entirely for such services but we need some way to increase this limit. This patch adds a sv_maxconn field to the svc_serv struct. When it's set to 0, we use the current method to calculate the max number of connections. RPC services can then set this on an as-needed basis. Signed-off-by: Jeff Layton <jlayton@redhat.com> Acked-by: Neil Brown <neilb@suse.de> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>

| * rpc: add service field to new upcallOlga Kornievskaia2008-12-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch extends the new upcall with a "service" field that currently can have 2 values: "*" or "nfs". These values specify matching rules for principals in the keytab file. The "*" means that gssd is allowed to use "root", "nfs", or "host" keytab entries while the other option requires "nfs". Restricting gssd to use the "nfs" principal is needed for when the server performs a callback to the client. The server in this case has to authenticate itself as an "nfs" principal. We also need "service" field to distiguish between two client-side cases both currently using a uid of 0: the case of regular file access by the root user, and the case of state-management calls (such as setclientid) which should use a keytab for authentication. (And the upcall should fail if an appropriate principal can't be found.) Signed-off: Olga Kornievskaia <aglo@citi.umich.edu> Signed-off-by: J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Two principals are involved in krb5 authentication: the target, who we authenticate *to* (normally the name of the server, like nfs/server.citi.umich.edu@CITI.UMICH.EDU), and the source, we we authenticate *as* (normally a user, like bfields@UMICH.EDU) In the case of NFSv4 callbacks, the target of the callback should be the source of the client's setclientid call, and the source should be the nfs server's own principal. Therefore we allow svcgssd to pass down the name of the principal that just authenticated, so that on setclientid we can store that principal name with the new client, to be used later on callbacks.

| * rpc: implement new upcall\"J. Bruce Fields\2008-12-23
| | | | | | | | | | | | | | | | | | | | | | | | Implement the new upcall. We decide which version of the upcall gssd will use (new or old), by creating both pipes (the new one named "gssd", the old one named after the mechanism (e.g., "krb5")), and then waiting to see which version gssd actually opens. We don't permit pipes of the two different types to be opened at once. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a global variable pipe_version which will eventually be used to keep track of which version of the upcall gssd is using. For now, though, it only keeps track of whether any pipe is open or not; it is negative if not, zero if one is opened. We use this to wait for the first gssd to open a pipe. (Minor digression: note this waits only for the very first open of any pipe, not for the first open of a pipe for a given auth; thus we still need the RPC_PIPE_WAIT_FOR_OPEN behavior to wait for gssd to open new pipes that pop up on subsequent mounts.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I can't see any reason we need to call this until either the kernel or the last gssd closes the pipe. Also, this allows to guarantee that open_pipe and release_pipe are called strictly in pairs; open_pipe on gssd's first open, release_pipe on gssd's last close (or on the close of the kernel side of the pipe, if that comes first). That will make it very easy for the gss code to keep track of which pipes gssd is using. Signed-off-by: J.

| * rpc: add an rpc_pipe_open method\"J. Bruce Fields\2008-12-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We want to transition to a new gssd upcall which is text-based and more easily extensible. To simplify upgrades, as well as testing and debugging, it will help if we can upgrade gssd (to a version which understands the new upcall) without having to choose at boot (or module-load) time whether we want the new or the old upcall. We will do this by providing two different pipes: one named, as currently, after the mechanism (normally "krb5"), and supporting the old upcall. One named "gssd" and supporting the new upcall version. We allow gssd to indicate which version it supports by its choice of which pipe to open. As we have no interest in supporting *simultaneous* use of both versions, we'll forbid opening both pipes at the same time. So, add a new pipe_open callback to the rpc_pipefs api, which the gss code can use to track which pipes have been open, and to refuse opens of incompatible pipes. We only need this to be called on the first open of a given pipe. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| * sunrpc: fix code that makes auth_gss send destroy_cred message (try #2)Jeff Layton2008-12-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a bit of a chicken and egg problem when it comes to destroying auth_gss credentials. When we destroy the last instance of a GSSAPI RPC credential, we should send a NULL RPC call with a GSS procedure of RPCSEC_GSS_DESTROY to hint to the server that it can destroy those creds. This isn't happening because we're setting clearing the uptodate bit on the credentials and then setting the operations to the gss_nullops. When we go to do the RPC call, we try to refresh the creds. That fails with -EACCES and the call fails. Fix this by not clearing the UPTODATE bit for the credentials and adding a new crdestroy op for gss_nullops that just tears down the cred without trying to destroy the context. The only difference between this patch and the first one is the removal of some minor formatting deltas.

| * optimize attribute timeouts for "noac" and "actimeo=0"Peter Staubach2008-12-23

I've been looking at a bugzilla which describes a problem where a customer was advised to use either the "noac" or "actimeo=0" mount options to solve a consistency problem that they were seeing in the file attributes. It turned out that this solution did not work reliably for them because sometimes, the local attribute cache was believed to be valid and not timed out. (With an attribute cache timeout of 0, the cache should always appear to be timed out.) In looking at this situation, it appears to me that the problem is that the attribute cache timeout code has an off-by-one error in it. It is assuming that the cache is valid in the region, [read_cache_jiffies, read_cache_jiffies + attrtimeo]. The cache should be considered valid only in the region, [read_cache_jiffies, read_cache_jiffies + attrtimeo). With this change, the options, "noac" and "actimeo=0", work as originally expected. This problem was previously addressed by special casing the attrtimeo == 0 case. However, since the problem is only an off- by-one error, the cleaner solution is address the off-by-one error and thus, not require the special case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Somehow, this escaped the previous purge. There should be no need to keep any extra locks in the XDR callbacks. The NFS client XDR code only writes into private objects, whereas all reads of shared objects are confined to fields that do not change, such as filehandles... Ditto for lockd, the NFSv2/v3 client mount code, and rpcbind. The nfsd XDR code may require the BKL, but since it does a synchronous RPC call from a thread that already holds the lock, that issue is moot.

Add a try_module_get call to the svc_addsock function for transport instances added by this function. Signed-off-by: Tom Tucker <tom@opengridcomputing.com> Signed-off-by: J.

| * | / SUNRPC: Fix a performance regression in the RPC authentication codeTrond Myklebust2008-11-20
| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a regression reported by Max Kellermann whereby kernel profiling showed that his clients were spending 45% of their time in rpcauth_lookup_credcache. It turns out that although his processes had identical uid/gid/groups, generic_match() was failing to detect this, because the task->group_info pointers were not shared. This again lead to the creation of a huge number of identical credentials at the RPC layer. The regression is fixed by comparing the contents of task->group_info if the actual pointers are not identical.
