* NFSv4: Don't use cred->cr_ops->cr_name in nfs4_proc_setclientid()Trond Myklebust2008-04-19
| | | | | | | | | With the recent change to generic creds, we can no longer use cred->cr_ops->cr_name to distinguish between RPCSEC_GSS principals and AUTH_SYS/AUTH_NULL identities. Replace it with the rpc_authops->au_name instead... Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NLM/lockd: Add a reference counter to struct nlm_rqstTrond Myklebust2008-04-19
| | | | | | | | When we replace the existing synchronous RPC calls with asynchronous calls, the reference count will be needed in order to allow us to examine the result of the RPC call. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Only increment the sequence id if the server saw itTrond Myklebust2008-04-19
| | | | | | | | | | | | It is quite possible that the OPEN, CLOSE, LOCK, LOCKU,... compounds fail before the actual stateful operation has been executed (for instance in the PUTFH call). There is no way to tell from the overall status result which operations were executed from the COMPOUND. The fix is to move incrementing of the sequence id into the XDR layer, so that we do it as we process the results from the stateful operation.

* SUNRPC: Fix up xprt_write_space()Trond Myklebust2008-04-19
| | | | | | | | | | | | | | | | | | The rest of the networking layer uses SOCK_ASYNC_NOSPACE to signal whether or not we have someone waiting for buffer memory. Convert the SUNRPC layer to use the same idiom. Remove the unlikely()s in xs_udp_write_space and xs_tcp_write_space. In fact, the most common case will be that there is nobody waiting for buffer space. SOCK_NOSPACE is there to tell the TCP layer whether or not the cwnd was limited by the application window. Ensure that we follow the same idiom as the rest of the networking layer here too. Finally, ensure that we clear SOCK_ASYNC_NOSPACE once we wake up, so that write_space() doesn't keep waking things up on xprt->pending. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* NFS: Save the values of the "mount*=" mount optionsChuck Lever2008-03-19
| | | | | | | | | | | | | Save the value of the mountproto= mountport= mountvers= and mountaddr= options so that these values can be displayed later via nfs_show_options(). This preserves the intent of the original mount options, should the file system need to be remounted based on what's displayed in /proc/mounts.

* NFS: Save the value of the "port=" mount optionChuck Lever2008-03-19
| | | | | | | | | | | | | | | | | | | | | | | During a remount based on the mount options displayed in /proc/mounts, we want to preserve the original behavior of the mount request. Let's save the original setting of the "port=" mount option in the mount's nfs_server structure. This allows us to simplify the default behavior of port setting for NFSv4 mounts: by default, NFSv2/3 mounts first try an RPC bind to determine the NFS server's port, unless the user specified the "port=" mount option; Users can force the client to skip the RPC bind by explicitly specifying "port=<value>". NFSv4, by contrast, assumes the NFS server port is 2049 and skips the RPC bind, unless the user specifies "port=". Users can force an RPC bind for NFSv4 by explicitly specifying "port=0". I added a couple of extra comments to clarify this behavior.

| * sched: improve affine wakeupsIngo Molnar2008-03-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | improve affine wakeups. Maintain the 'overlap' metric based on CFS's sum_exec_runtime - which means the amount of time a task executes after it wakes up some other task. Use the 'overlap' for the wakeup decisions: if the 'overlap' is short, it means there's strong workload coupling between this task and the woken up task. If the 'overlap' is large then the workload is decoupled and the scheduler will move them to separate CPUs more easily. ( Also slightly move the preempt_check within try_to_wake_up() - this has no effect on functionality but allows 'early wakeups' (for still-on-rq tasks) to be correctly accounted as well.)

I think its the following race: poll says netif_rx_complete poll calls enable_cb enable_cb opens the interrupt mask a new packet comes, an interrupt is triggered----\ enable_cb sees that there is more work | enable_cb disables the interrupt | . V . interrupt is delivered . skb_recv_done does atomic napi test, ok some waiting disable_cb is called->check fails->bang! . poll would do napi check poll would do disable_cb The fix is to let enable_cb not disable the interrupt again, but expect the caller to do the cleanup if it returns false. In that case, the interrupt is only disabled, if the napi test_set_bit was successful.

It's also currently creating a rather ugly alignment hole in struct dst. Therefore this patch moves it from there into struct rt6_info. Above patch changes the cache line alignment, especially member __refcnt. I did a testing by adding 2 unsigned long pading before lastuse, so the 3 members, lastuse/__refcnt/__use, are moved to next cache line. The performance is recovered. I created a patch to rearrange the members in struct dst_entry. With Eric and Valdis Kletnieks's suggestion, I made finer arrangement. 1) Move tclassid under ops in case CONFIG_NET_CLS_ROUTE=y. So sizeof(dst_entry)=200 no matter if CONFIG_NET_CLS_ROUTE=y/n. I tested many patches on my 16-core tigerton by moving tclassid to different place. It looks like tclassid could also have impact on performance. If moving tclassid before metrics, or just don't move tclassid, the performance isn't good. So I move it behind metrics. 2) Add comments before __refcnt. On 16-core tigerton: If CONFIG_NET_CLS_ROUTE=y, the result with below patch is about 18% better than the one without the patch; If CONFIG_NET_CLS_ROUTE=n, the result with below patch is about 30% better than the one without the patch. With 32bit 2.6.25-rc1 on 8-core stoakley, the new patch doesn't introduce regression. Thank Eric, Valdis, and David!

The problem is that dentries subtree of /proc/net directory has fancy revalidation rules to make processes living in different net namespaces see different entries in /proc/net subtree, but currently, tasks see in the /proc/net subdir the contents of any other namespace, depending on who opened the file first. The proposed fix is to turn /proc/net into a symlink, which points to /proc/self/net, which in turn shows what previously was in /proc/net - the network-related info, from the net namespace the appropriate task lives in. # ls -l /proc/net lrwxrwxrwx 1 root root 8 Mar 5 15:17 /proc/net -> self/net In other words - this behaves like /proc/mounts, but unlike "mounts", "net" is not a file, but a directory. Changes from v2: * Fixed discrepancy of /proc/net nlink count and selinux labeling screwup pointed out by Stephen. To get the correct nlink count the ->getattr callback for /proc/net is overridden to read one from the net->proc_net entry. To make selinux still work the net->proc_net entry is initialized properly, i.e. with the "net" name and the proc_net parent.
