2006-09-27[PATCH] Really ignore kmem_cache_destroy return valueAlexey Dobriyan2-6/+5
* Rougly half of callers already do it by not checking return value * Code in drivers/acpi/osl.c does the following to be sure: (void)kmem_cache_destroy(cache); * Those who check it printk something, however, slab_error already printed the name of failed cache. * XFS BUGs on failed kmem_cache_destroy which is not the decision low-level filesystem driver should make.

2006-09-25[NetLabel]: make the CIPSOv4 cache spinlocks bottom half safePaul Moore1-8/+8
The CIPSOv4 cache traversal routines are triggered both the userspace events (cache invalidation due to DOI removal or updated SELinux policy) and network packet processing events. As a result there is a problem with the existing CIPSOv4 cache spinlocks as they are not bottom-half/softirq safe. This patch converts the CIPSOv4 cache spin_[un]lock() calls into spin_[un]lock_bh() calls to address this problem. Signed-off-by: Paul Moore <paul.moore@hp.com> Signed-off-by: David S.

2006-09-25[NetLabel]: correct improper handling of non-NetLabel peer contextsPaul Moore2-15/+56
Fix a problem where NetLabel would always set the value of sk_security_struct->peer_sid in selinux_netlbl_sock_graft() to the context of the socket, causing problems when users would query the context of the connection. This patch fixes this so that the value in sk_security_struct->peer_sid is only set when the connection is NetLabel based, otherwise the value is untouched.

2006-09-22SUNRPC: export new RPC client functions with _GPLChuck Lever1-5/+5
This patch is optional. It has been suggested that the RPC client internal functions used by upper layer protocols (such as NFS) be exported via EXPORT_SYMBOL_GPL. This patch does that.

2006-09-22SUNRPC: Eliminate xprt_create_proto and rpc_create_clientChuck Lever4-125/+1
The two function call API for creating a new RPC client is now obsolete. Remove it. Also, remove an unnecessary check to see whether the caller is capable of using privileged network services. The kernel RPC client always uses a privileged ephemeral port by default; callers are responsible for checking the authority of users to make use of any RPC service, or for specifying that a nonprivileged port is acceptable.

2006-09-22SUNRPC: use sockaddr + size when creating remote transport endpointsChuck Lever2-0/+136
Prepare for more generic transport endpoint handling needed by transports that might use different forms of addressing, such as IPv6. Introduce a single function call to replace the two-call xprt_create_proto/rpc_create_client API. Define a new rpc_create_args structure that allows callers to pass in remote endpoint addresses of varying length. Test-plan: Compile kernel with CONFIG_NFS enabled.

2006-09-22SUNRPC: Use "sockaddr_storage" for storing RPC client's remote peer addressChuck Lever3-7/+13
IPv6 addresses are big (128 bytes). Now that no RPC client consumers treat the addr field in rpc_xprt structs as an opaque, and access it only via the API calls, we can safely widen the field in the rpc_xprt struct to accomodate larger addresses.

2006-09-22SUNRPC: Create API for displaying remote peer addressChuck Lever1-0/+13
Provide an API for formatting the remote peer address for printing without exposing its internal structure. The address could be dynamic, so we support a function call to get the address rather than reading it straight out of a structure. Test-plan: Destructive testing (unplugging the network temporarily). Probably need to rig a server where certain services aren't running, or that returns an error for some typical operation.

2006-09-22SUNRPC: Introduce transport switch callout for pluggable rpcbindChuck Lever3-4/+5
Introduce a clean transport switch API for plugging in different types of rpcbind mechanisms. For instance, rpcbind can cleanly replace the existing portmapper client, or a transport can choose to implement RPC binding any way it likes. Test plan: Destructive testing (unplugging the network temporarily). Connectathon with UDP and TCP. NFSv2/3 and NFSv4 mounting should be carefully checked.

2006-09-22SUNRPC: Make RPC portmapper use per-transport storageChuck Lever3-61/+106
Move connection and bind state that was maintained in the rpc_clnt structure to the rpc_xprt structure. This will allow the creation of a clean API for plugging in different types of bind mechanisms. This brings improvements such as the elimination of a single spin lock to control serialization for all in-kernel RPC binding. A set of per-xprt bitops is used to serialize tasks during RPC binding, just like it now works for making RPC transport connections. Test-plan: Destructive testing (unplugging the network temporarily). Connectathon with UDP and TCP. NFSv2/3 and NFSv4 mounting should be carefully checked.
