* Input: wm97xx - enable sub-drivers by defaultMark Brown2008-07-29
| | | | | | | | | | | | | Currently the support for each WM97xx touchscreen model is compiled out by default, meaning that the default configuration when the driver is built is for it to support no hardware. This is suboptimal and leads to problems like distribution kernels shipping a non-functional driver. Change the default to support all controllers and update the help text to reflect this.

| | | * svcrdma: Limit ORD based on client's advertised IRDTom Tucker2008-07-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When adapters have differing IRD limits, the RDMA transport will fail to connect properly. The RDMA transport should use the client's advertised inbound read limit when computing its outbound read limit. For iWARP transports, there is currently no standard for exchanging IRD/ORD during connection establishment so the 'responder_resources' field in the connect event is the local device's limit. The RDMA transport can be configured to use a smaller ORD by writing the desired number to the /proc/sys/sunrpc/svc_rdma/max_outbound_read_requests file.

A "loose" mask (SHUTDOWN_SIGS) that it uses when receiving network requests, and then a more "strict" mask (ALLOWED_SIGS, which is just SIGKILL) that it allows when doing the actual operation on the local storage. This is apparently unnecessarily complicated. The underlying filesystem should be able to sanely handle a signal in the middle of an operation. This patch removes the signal mask handling from knfsd altogether. When knfsd is started as a kthread, all signals are ignored. It then allows all of the signals in SHUTDOWN_SIGS. There's no need to set the mask as well. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>

This problem can also occur after memory pressure on the server, particularly when the client side is quiet for some time." This occurs because the filehandle points to a directory whose parents are no longer in the dentry cache, and we're attempting to reconnect the directory to its parents without adequate permissions to perform lookups in the parent directories. We can therefore fix the problem by acquiring the necessary capabilities before attempting the reconnection. We do this only in the no_subtree_check case, since the documented behavior of the subtree_check export option requires the server to check that the user has lookup permissions on all parents. The subtree_check case still has a problem, since reconnect_path() unnecessarily requires both read and lookup permissions on all parent directories. However, a fix in that case would be more delicate, and use of subtree_check is already discouraged for other reasons.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Initialize the value used for the confounder to a random value rather than starting from zero. Allow for confounders of length 8 or 16 (which will be needed for AES). Signed-off-by: Kevin Coffman <kwc@citi.umich.edu> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
