| * sunrpc: move the close processing after do recvfrom methodWei Yongjun2009-08-27
| | | | | | | | | | | | | | | | | | | | | | sunrpc: "Move close processing to a single place" (d7979ae4a050a45b78af51832475001b68263d2a) moved the close processing before the recvfrom method. This may cause the close processing never to execute. So this patch moves it to the right place. Signed-off-by: Wei Yongjun <yjwei@cn.fujitsu.com> Signed-off-by: J.

| * sunrpc: reply AUTH_BADCRED to RPCSEC_GSS with unknown serviceWei Yongjun2009-08-25
| | | | | | | | | | | | | | | | | | | | | | | | When an RPC message is received with RPCSEC_GSS with an unknown service (not RPC_GSS_SVC_NONE, RPC_GSS_SVC_INTEGRITY, or RPC_GSS_SVC_PRIVACY), svcauth_gss_accept() returns AUTH_BADCRED, but svcauth_gss_release() subsequently drops the response entirely, discarding the error. Fix that so the AUTH_BADCRED error is returned to the client. Signed-off-by: Wei Yongjun <yjwei@cn.fujitsu.com> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
| * knfsd: Replace lock_kernel with a mutex in nfsd pool stats.Ryusei Yamaguchi2009-08-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lock_kernel() in knfsd was replaced with a mutex. The later commit 03cf6c9f49a8fea953d38648d016e3f46e814991 ("knfsd: add file to export stats about nfsd pools") did not follow that change. This patch fixes the issue. Also move the get and put of nfsd_serv to the open and close methods (instead of start and stop methods) to allow atomic check and increment of reference count in the open method (where we can still return an error).

| | | | | | | | | | | | | | | | | | | | | | | | | | | When we look up an entry in the uid->gidlist cache, we take a reference to the content but don't drop the reference to the cache entry.

| | | | | | | | | | | | | | | | | | | | | | | | | | | If cache_defer_req did not leave the request on a queue, then it could possibly have waited long enough that the cache became valid.

| * | sunrpc/cache: make sure deferred requests eventually get revisited.NeilBrown2009-08-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While deferred requests normally get revisited quite quickly, it is possible for a request to remain in the deferral queue when the cache item is discarded. We can easily make sure that doesn't happen by calling cache_revisit_request just before the final 'put'. Also there is a small chance that a race would cause one thread to defer a request against a cache item while another thread is failing to queue an upcall for that item. So when the upcall fails, make sure to revisit all deferred requests. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>

| * | SUNRPC: handle IPv6 PKTINFO when extracting destination addressChuck Lever2009-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PKTINFO is needed to scrape the caller's IP address off the socket so RPC datagram replies are routed correctly. Fill in missing pieces in the kernel RPC server's UDP receive path to request IPv6 PKTINFO and correctly parse the IPv6 cmsg header. Without this patch, kernel RPC services drop all incoming requests on UDP on IPv6.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The NFSv4 and NFSv4.1 protocols both allow for the redirection of a client from one server to another in order to support filesystem migration and replication. For full protocol support, we need to add the ability to convert a DNS host name into an IP address that we can feed to the RPC client. We'll reuse the sunrpc cache, now that it has been converted to work with rpc_pipefs. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| | * | | SUNRPC: Allow the cache_detail to specify alternative upcall mechanismsTrond Myklebust2009-08-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For events that are rare, such as referral DNS lookups, it makes limited sense to have a daemon constantly listening for upcalls on a channel. An alternative in those cases might simply be to run the app that fills the cache using call_usermodehelper_exec() and friends. The following patch allows the cache_detail to specify alternative upcall mechanisms for these particular cases. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
| | * | | SUNRPC: Remove the global temporary write buffer in net/sunrpc/cache.cTrond Myklebust2009-08-09

This patch therefore replaces the static buffer 'write_buf', which can only be used by one writer at a time, with use of the page cache as the temporary buffer for downcalls. We still fall back to using the the old global buffer if the downcall is larger than PAGE_CACHE_SIZE, since this is apparently needed by the SPKM security context initialisation. It then replaces the use of the global 'queue_io_mutex' with the inode->i_mutex in cache_read() and cache_write(). Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to allow rpc_pipefs to create directories with different types of subtrees, it is useful to allow the caller to customise the subtree filling process. In order to do so, we separate out the parts which are specific to making an RPC client directory, and put them in a separate helper, then we convert the process of filling the directory contents into a callback.

Another point is that if we open code __rpc_lookup_path() here, then we can avoid looking up the entire parent directory path over and over again: it doesn't change.
