* NFS: Expand server address storage in nfs_client structChuck Lever2008-01-301-1/+2
| | | | | | | | | | | Prepare for managing larger addresses in the NFS client by widening the nfs_client struct's cl_addr field. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Cc: Aurelien Charbon <aurelien.charbon@ext.bull.net> (Modified to work with the new parameters for nfs_alloc_client) Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFS: Increase size of cl_ipaddr field to hold IPv6 addressesChuck Lever2008-01-301-1/+1
| | | | | | | | | The nfs_client's cl_ipaddr field needs to be larger to hold strings that represent IPv6 addresses. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Cc: Aurelien Charbon <aurelien.charbon@ext.bull.net> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFS: Ensure NFSv4 SETCLIENTID send buffer is large enoughChuck Lever2008-01-301-6/+7
| | | | | | | | | Ensure that the RPC buffer size specified for NFSv4 SETCLIENTID procedures matches what we are encoding into the buffer. See the definition of struct nfs4_setclientid {} and the encode_setclientid() function. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Move universal address definitions to global headerChuck Lever2008-01-301-0/+39
| | | | | | | | | | Universal addresses are defined in RFC 1833 and clarified in RFC 3530. We need to use them in several places in the NFS and RPC clients, so move the relevant definition and block comment to an appropriate global include file.

| | | | | | | | | | | | | | | | | | | | | | | | Basically, this piece looks relatively easy. Namespace is already available on the dst entry via device and the device is safe to dereferrence.

| | | | | | | | | | | | | | | | | | | | | | Convert packet schedulers to use the netlink API. Unfortunately a gradual conversion is not possible without breaking compilation in the middle or adding lots of casts, so this patch converts them all in one step. The patch has been mostly generated automatically with some minor edits to at least allow seperate conversion of classifiers and actions.

| * [DST]: shrinks sizeof(struct rtable) by 64 bytes on x86_64Eric Dumazet2008-01-281-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On x86_64, sizeof(struct rtable) is 0x148, which is rounded up to 0x180 bytes by SLAB allocator. We can reduce this to exactly 0x140 bytes, without alignment overhead, and store 12 struct rtable per PAGE instead of 10. rate_tokens is currently defined as an "unsigned long", while its content should not exceed 6*HZ. It can safely be converted to an unsigned int. Moving tclassid right after rate_tokens to fill the 4 bytes hole permits to save 8 bytes on 'struct dst_entry', which finally permits to save 8 bytes on 'struct rtable' Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

| * [NETNS][FRAGS]: Make the pernet subsystem for fragments.Pavel Emelyanov2008-01-281-0/+1
| | | | | | | | | | | | | | | | | | | | On namespace start we mainly prepare the ctl variables. When the namespace is stopped we have to kill all the fragments that point to this namespace. The inet_frags_exit_net() handles it. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
| * [NETNS][FRAGS]: Make the LRU list per namespace.Pavel Emelyanov2008-01-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The inet_frags.lru_list is used for evicting only, so we have to make it per-namespace, to evict only those fragments, who's namespace exceeded its high threshold, but not the whole hash. Besides, this helps to avoid long loops in evictor. The spinlock is not per-namespace because it protects the hash table as well, which is global.

| * [NETNS][FRAGS]: Isolate the secret interval from namespaces.Pavel Emelyanov2008-01-282-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | Since we have one hashtable to lookup the fragment, having different secret_interval-s for hash rebuild doesn't make sense, so move this one to inet_frags. The inet_frags_ctl becomes empty after this, so remove it. The appropriate ctl table is kept read-only in namespaces. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
| * [NETNS][FRAGS]: Make thresholds work in namespaces.Pavel Emelyanov2008-01-281-2/+2
| | | | | | | | | | | | | | | | | | | | | | This is the same as with the timeout variable. Currently, after exceeding the high threshold _all_ the fragments are evicted, but it will be fixed in later patch. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
| * [NETNS][FRAGS]: Make the net.ipv4.ipfrag_timeout work in namespaces.Pavel Emelyanov2008-01-281-1/+3
| | | | | | | | | | | | | | | | | | | | | | Move it to the netns_frags, adjust the usage and make the appropriate ctl table writable. Now fragment, that live in different namespaces can live for different times. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
| * [NETNS][FRAGS]: Duplicate sysctl tables for new namespaces.Pavel Emelyanov2008-01-282-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | Each namespace has to have own tables to tune their different parameters, so duplicate the tables and register them. All the tables in sub-namespaces are temporarily made read-only. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
| * [NETNS][FRAGS]: Make the mem counter per-namespace.Pavel Emelyanov2008-01-283-4/+4

| * [NETNS][FRAGS]: Make the nqueues counter per-namespace.Pavel Emelyanov2008-01-283-3/+5
| | | | | | | | | | | | | | | | This is simple - just move the variable from struct inet_frags to struct netns_frags and adjust the usage appropriately. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
| * [NETNS][FRAGS]: Make the inet_frag_queue lookup work in namespaces.Pavel Emelyanov2008-01-283-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since fragment management code is consolidated, we cannot have the pointer from inet_frag_queue to struct net, since we must know what king of fragment this is. So, I introduce the netns_frags structure. This one is currently empty, but will be eventually filled with per-namespace attributes. Each inet_frag_queue is tagged with this one. The conntrack_reasm is not "netns-izated", so it has one static netns_frags instance to keep working in init namespace. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
| * [NETNS][FRAGS]: Move ctl tables around.Pavel Emelyanov2008-01-283-7/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a preparation for sysctl netns-ization. Move the ctl tables to the files, where the tuning variables reside. Plus make the helpers to register the tables. This will simplify the later patches and will keep similar things closer to each other. ipv4, ipv6 and conntrack_reasm are patched differently, but the result is all the tables are in appropriate files.
