| * | SUNRPC: setup rpcbind clients if service requires itStanislav Kinsbursky2011-10-251-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New function ("svc_uses_rpcbind") will be used to detect, that new service will send portmapper register calls. For such services we will create rpcbind clients and remove all stale portmap registrations. Also, svc_rpcb_cleanup() will be set as sv_shutdown callback for such services in case of this field wasn't initialized earlier. This will allow to destroy rpcbind clients when no other users of them left. Note: Currently, any creating service will be detected as portmap user. Probably, this is wrong. But now it depends on program versions "vs_hidden" flag. Signed-off-by: Stanislav Kinsbursky <skinsbursky@parallels.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| * | SUNRPC: introduce helpers for reference counted rpcbind clientsStanislav Kinsbursky2011-10-251-0/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | v6: 1) added write memory barrier to rpcb_set_local to make sure, that rpcbind clients become valid before rpcb_users assignment 2) explicitly set rpcb_users to 1 instead of incrementing it (looks clearer from my pow). v5: fixed races with rpcb_users in rpcb_get_local() This helpers will be used for dynamical creation and destruction of rpcbind clients. Variable rpcb_users is actually a counter of lauched RPC services. If rpcbind clients has been created already, then we just increase rpcb_users.

| * | NFS/sunrpc: don't use a credential with extra groups.NeilBrown2011-10-251-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sunrpc layer keeps a cache of recently used credentials and 'unx_match' is used to find the credential which matches the current process. However unx_match allows a match when the cached credential has extra groups at the end of uc_gids list which are not in the process group list. So if a process with a list of (say) 4 group accesses a file and gains access because of the last group in the list, then another process with the same uid and gid, and a gid list being the first tree of the gids of the original process tries to access the file, it will be granted access even though it shouldn't as the wrong rpc credential will be used.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When (de)configuring a vlan interface, the IFF_ALLMULTI ans IFF_PROMISC flags are cleared or set on the underlying interface. So, if these flags are changed on a vlan interface that is not up, the flags underlying interface might be set or cleared twice. Only propagating flag changes when a device is up makes sure this does not happen. It also makes sure that an underlying device is not set to promiscuous or allmulti mode for a vlan device that is down. Signed-off-by: Matthijs Kooijman <matthijs@stdin.nl> Signed-off-by: David S.

This is true for the ipv4 implementation, but not for the ipv6 one. Instead of changing the users, change the ipv6 implementation to behave like the ipv4 version by only providing the dst_entry result in the success case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The route lookup to find a previously auto-configured route for a prefixes used to use rt6_lookup(), with the prefix from the RA used as an address. However, that kind of lookup ignores routing tables, the prefix length and route flags, so when there were other matching routes, even in different tables and/or with a different prefix length, the wrong route would be manipulated. Now, a new function "addrconf_get_prefix_route()" is used for the route lookup, which searches in RT6_TABLE_PREFIX and takes the prefix-length and route flags into account.

Each time the netdevice_notifier is triggered, it'll do some stuff... including a lookup of its own pernet stuff with net_generic(). If the net_generic() call ever returns NULL, the caif code will BUG(). That doesn't seem *so* unreasonable, I suppose — it does seem like it should never happen. However, it *does* happen. When we clone a network namespace, setup_net() runs through all the pernet_operations one at a time. It gets to loopback before it gets to caif. And loopback_net_init() registers a netdevice... while caif hasn't been initialised. So the caif netdevice notifier triggers, and immediately goes BUG(). We could imagine a complex and overengineered solution to this generic class of problems, but this patch takes the simple approach. It just makes caif_device_notify() *not* go looking for its pernet data structures if the device it's being notified about isn't a caif device in the first place.
